DSCF5081 K8JTKHey gang,
I’ve been playing around with a couple new radios. With the holidays approaching, these will make great gift ideas.

Cheap radios for new or young hams are hard to come by. Many opted for the under $30 Baeofung (or Pofung) UV-5R and for good reason. They’re cheap. Perfect options for new hams, young hams, or public service events were radios are prone to damage and misuse. Destroy it and its $30 vs a couple hundred, or 7, to replace. Cheap radios could replace older radios that maybe didn’t have PL, were lower power, or single band. You got what you paid for though. Inconsistencies in firmware versions lead to differing sets of features, programming software wasn’t easy to use, neither was installing the programming cable, complaints about the lack of support, and lack of a usable manual. I stopped using these radios because of the many tests proving they were good about transmitting everywhere at once (across the entire band). As hams we are given plenty of leeway in how we use our frequencies. It’s up to each of us to make sure our radios comply with Part 97 and do not interfere with other licensed radio services. The ARRL published their findings in a November 2015 QST article. Ohio Section Technical Specialist Dave – KD8TWG demonstrated this with a couple of radios he had purchased: https://kd8twg.net/2015/10/17/a-quick-and-unscientific-spectral-analysis-of-two-baofeng-radios/.

Ok, so don’t use these radios. What radio, that meets Part 97 requirements, is available for the price? This was a problem. There was no real option. About the cheapest dual-band radio was $150. DMR radios competed on price and features but, until recently, were only single band. I finally found a better option. Unfortunately, the company has “Baofeng” in the name which makes things even more confusing. A company called “Baofeng Tech” or BTech, is a US based company offering a similar radio called the UV-5X3 for under $60.

The radio looks and acts like a UV-5R. Baofeng Tech updates the firmware, modifies the radio installing better filtering on the transmitter, and includes an easy-to-read nicely printed 85 page manual. The UV-5X3 comes with all the same accessories including belt clip, antennas, charger, and ear piece. All original Baofeng accessories work too. To my surprise, they even squeezed in the 220 MHz (1.25m) band! Baofeng Tech assured me their radios meet spectral requirements for Part 97. I had mine tested at the Cleveland Hamfest by KD8TWG. On VHF the 3rd harmonic was a little higher than 40db down, UHF was spot-on. The CHRIP free programming software is the only programmer that currently works with this radio. RT Systems UV-5R programmer for the original Baofeng radios does not work with the UV-5X3.

Now there’s no excuse to get a very reasonably priced radio compliant with Part 97 spectral requirements. It even comes with free shipping if bought through Amazon. For someone looking to play around with 220, this is a great tri-bander radio. Check out this radio as an option, from a US company, for new or young hams: https://baofengtech.com/uv-5×3. Product images from Baofeng Tech.

I’ve wanted to install a dual-band DMR mobile radio in the shack. Yeah, all the DMR repeaters in the area are UHF. I like to have the flexibility of a dual-band. Connect Systems was one for the first, if not the first, to release a dual-band DMR mobile radio earlier this year. Talking with Jerry at Dayton (President of Connect Systems), they had just shipped the first batch of CS800D radios and were expecting to get another batch ‘in a couple months.’ I heard very good things from hams that have purchased from Jerry’s company previously. Connect Systems is accessible via email and social media for support, they worked to fully resolve product issues, fixed issues with firmware quickly, and let customers try out their new equipment while seeking feedback. I didn’t hesitate to get on the waiting list.

I finally got the radio at the beginning of August and I like it a lot. The radio itself looks like a Motorola CM300D or nearly identical in layout, including microphone, to the Kenwood TM-281A. Radio covers VHF: 136-174 @ 50W, UHF: 400-470 @ 45W. The head and microphone are removable and extendable with a cat5 Ethernet cable. It will hold 4,000 channels and 130,000 contacts with firmware updates – more contacts than the ENTIRE DMR-MARC user database! It’s got a couple quarks which I’m told are to be fixed in future firmware releases. Biggest annoyance being the display doesn’t always update after a button is pressed. The programming software is straight forward if you’ve ever programmed a DMR radio before. The Ohio Section website has a pre-built codeplug: http://arrl-ohio.org/digital/digital.html. N0GSG makes a great codeplug editor and codeplug converter that I found useful: http://n0gsg.com/contact-manager/. His editor now supports the CS800D, TYT MD2017 & MD9600.

The Connect Systems CS800D was a little pricey when I bought it ($399 + $15 for the programming cable) but has since dropped in price to $299. I feel this radio could have been more popular if the radio was not released in batches. Jerry was great about communicating and explaining the situation. Like any distributor, they were beholden to the timetables from their manufacturer. Nothing they could do about it. I think that allowed other options to enter the market sooner and resulted in lost potential sales. It’s a great radio and recommended for someone looking for a dual-band DMR mobile radio from a US based company. CS800D product page: http://www.connectsystems.com/products/top/radios%20CS800D.htm.

Technical Specialist reports

Dave – KD8TWG has been busy as usual. In addition to testing radios at the Cleveland Hamfest, he tackled the issue of “operational security.” This has been a topic of discussion in the area as of late and on social media. He was seeing arguments that operational frequencies needed to be obscured for the purposes of “securing” an operation. Without encryption, there is no such thing. As Dave points out, any modern scanner can scan VHF and UHF bands within seconds. It’s even easier with SDR receivers that allow you to look at the entire band scope at once. Check out his post about Hiding Frequencies for “Operational Security”: https://kd8twg.net/2017/08/14/opsec/.

In October, another Section Technical Specialist, Jason – WG8B, gave a presentation to the Dayton Amateur Radio Association about his area of expertise: bike mobile operations. Jason provided feedback on his program:

The briefing focused on using bike mobile capabilities to support public service events and covered topics such as

  • Suitable antennas. Bikes are not good ground planes, and dual band antennas are important when supporting public service events from a bike since carrying extra antennas and swapping them out is not easy.
  • Speakers and microphones that work while bicycling while allowing you to safely operate a bike.
  • Properly mounting equipment to not only protect the equipment but also protect the bicycle and rider.
  • APRS operations from a bicycle

Most of the questions revolved around antennas. I won’t repeat specific questions to protect the innocent so to speak, so I’ll just clarify what I think good antenna requirements are for VHF/UHF bicycle mobile operations. First and especially when supporting public service events, omnidrectional antennas are absolutely required. On a bike, there is no practical way to steer antennas with directional patterns whether they be gain antennas or magnetic loops. You will be changing direction quite frequently, and you need to hit repeaters from any aspect. Second, high-Q antennas such as magnetic loops require precise tuning, something that’s not possible while on a bicycle. Stick to an antenna that does not require tuning. Your radio should be working for you while on a bike during public service events not the other way around. There’s already enough going on, and safety is first. Third, any antenna bigger or longer than a bicycle flag is not likely safe. There are balance issues with weight above the bike’s center-of-gravity, and just about the worst shape aerodynamically is an antenna. So how hard do you want to pedal? Also, I’ve had problems with low hanging branches with just a bicycle flag. Anything taller is going to be problematic. My recommendation is still to use a dual band J pole like Ed Fong’s DBJ-2 taped to a bike flag or a single band half wave dipole like Larson’s NMO 150B HW. While not the absolutely best antennas performance-wise, they will still hit every repeater in my local area and then some with a 5W HT. And these are very simple and small form factor antennas that just work and won’t get in the way when on a bike.

Finally, if you would like to see the briefing, I’ve made it accessible here: https://drive.google.com/open?id=0B2Yn-_hki2v0blFnNVVRbW9kc3c

Jason’s presentation has lots of tips and pictures for making a bicycle mobile installation a success. If you would like to have Jason at your meeting, drop him a note!

DSCF5081 K8JTKHey gang,

October is National Cyber Security Awareness Month. I either made your eyes roll because security can be complicated or piqued your interest because of the TWO Equifax breaches. I can certainly get into the weeds with data and cybersecurity because it’s an interest of mine – as a user and programmer. Realizing that most readers won’t have a background in programming or system administration, I’ll set aside the technical details. I’ll briefly cover some cybersecurity issues and give tips anyone reading this article can use.

The whole concept of computing is built on trust. The list of things we trust is infinitely long: trust programmers of the operating system and program developers are following good practices. Trust the company stands behind their product, fixing problems and issues. Trust “Information Security Officers” of a company actually have a background in information security. Trust audits are taking place to uncover problems. Trust customer data is being stored in accordance with good security practices. Trust the website you’re browsing to is really CompanyWebsite.com. Trust “[insert name of company here] Free Wi-Fi” is really that company’s free Wi-Fi. Trust that devices in your home aren’t spying on you. You start to get the idea.

Security is a tradeoff between safety and convenience. Computing could be made very secure but those systems would be completely unusable due to the layers of security. There is no such thing as a “completely secure” system or device – it just means the mistakes, problems, and bugs haven’t been found yet. “Shellshock” is considered to be a very severe security bug. Disclosure came in September of 2014. This bug affected millions of servers connected to the internet. It was determined the bug, in some form, had existed in the UNIX (and Linux) command-line interface since 1989.
Humans program computers. Humans use computers. Humans make mistakes.

Hackers leverage these mistakes and use them to their advantage, often to gain unauthorized access. The word “hacker” has two meanings. “White-hat hackers” are the ones who experiment with and modify devices and software to make it work better. Hams are examples of these because we take commercial gear and make repeaters or use off-the-shelf routers for things like Mesh networking. “Black-hat hackers” are the bad guys and the ones we hear about on the news stealing credit card data from Target and personal data from Equifax. These are the ones I will be referring to.

Hollywood gives us the perception that hackers are in some 3rd-world country or in a dark basement, no lights, and only the glow of their computer screens. Hackers come from all parts of the world and sometimes are acting on a government’s behalf. In fact, legitimate companies exist solely to sell their black-hat hacking tools. They have buildings, employees, call centers, and help desks – as does any legitimate company.

What’s the motivation behind hacking?

Money. It’s hard not to tie everything back to money. The first reference to malicious hacking was “phreaking” (pronounced freaking. AKA: phone hacking) where one of the goals was to manipulate the public phone system and use it to make long-distance calls when it was very expensive to call around the world. More recent financial examples include everything from disrupting nation-states (economic), blackmail, and ransom payments for access to data. Ransomware encrypts all documents and pictures. It demands payment before it will (hopefully) decrypt your files allowing you to use those files again. Ransomware utilizes the same technology, strong encryption, which you use to securely transact with your bank online.

My social media, computer, or online account has no value [to me] / I only check email / I don’t store anything on my computer / why would anyone want access to my email or computer?

I hear these alot. Many of us don’t realize all the things a bad guy can do with computer access or an email account. Brian Krebs is a blogger who covers computing security and cybercrime on his website Krebs on Security. He is known for infiltrating underground cybercrime rings and writes about his experiences. His site is highly recommended reading for anyone with an interest in cybersecurity.

Brian posted two articles titled “The Value of a Hacked Email Account” and “The Scrap Value of a Hacked PC…” When signing up for any online service, an email address is almost always required. In 2013, according to Brian’s article, hackers who have access to email accounts can subsequently gain access to other services such as iTunes and sell that access for $8 each. FedEx, Continental, United accounts go for $6. Groupon, $5. Hosting and service accounts like GoDaddy, AT&T, Sprint, Verizon Wireless, and T-Mobile, $4 apiece. Facebook and Twitter accounts were $2.50/ea.

Aside from the monetary value, bad guys have access to family pictures, work documents, chat history, can change billing and deposit addresses on banking accounts, drain financials like 401K, bank or stock accounts, and target other individuals like family members. In 2012, a hacker went after Wired journalist Mat Honan locking him out of his digital life. The attacker used flaws in Amazon and Apple’s services, which helped them gain access to Mat’s Gmail and ultimately his Twitter account.

Access to a personal computer can be gained through a number of schemes including: fake ‘you have an out-of-date plugin/flash version’ on a webpage, receive an email about a past due invoice, notification of a problem with some shipment, or by innocently installing a program thought to be legitimate. A recent example of a compromised program was the widely popular PC maintenance program, CCleaner. Untold millions of people unknowingly downloaded a malicious version of the program from the vendor’s site.

A hacked PC can be used for: generating email spam, harvesting other accounts (see above), gain access to a work network, steal online game keys and characters, be part of a Denial of Service attack, infect other devices on the network (like DVRs), create fake eBay auctions, host child porn, capture images from web-cams or network cameras and use them for extortion purposes.

What can I do to protect myself?

Unfortunately in situations of compromise like Target and Equifax, there was nothing you could do – other than not use a credit card at Target or not apply for any kind of credit reported to Equifax. Unlikely for many. You can only react after-the-fact by closing accounts with fraudulent charges and place credit warnings or freezes on your credit.

The SANS Institute, which specializes in information security and cybersecurity training, offers a “monthly security awareness newsletter for everyone” called “Ouch!” Their October 2017 newsletter outlines five steps to help anyone overcome fears and securely use today’s technology. Check the newsletter for more information on these points.

  1. Social Engineering: is an old technique which creates a sense of urgency to tick people into giving up information they shouldn’t: someone needs money quickly, boss needs a password, the IRS is filing suit against you, Microsoft Tech Support calls you about a “virus” on your computer, etc. Never give a password, any personal information, or remote access to any solicitor.
  2. Passwords: Create unique, strong passwords for all online devices and online accounts. Use a password manager which will assist in creating strong passwords. LastPass utilizes a web interface and cloud storage, KeePass is an application and stores the database locally on your computer. Both are excellent solutions for a password manager.
    If you’re uncomfortable with a password manager, use pass-phrases which are passwords made up of multiple words. Passphrases can be written down, but store these in a secure location. Use two-step verification, often called two-factor authentication. Two-factor authentication (2FA) is a combination of something you know (your password) and something you have (a smartphone). A list of services offering 2FA with instructions can be found at: twofactorauth.org. Note: text messages are NOT a secure two-factor method because the cellphone network is not secure and attackers have been able to re-route text messages.
  3. Patches: Put all devices connected to the Internet behind a firewall (router) and keep all systems connected to the internet up-to-date. This includes home routers, computers, smartphones, tablets, streaming media devices, thermometers, Raspberry PIs, lights, automation systems, speakers, and video cameras. If devices are not being updated by the vendor, potentially dangerous mistakes are not being fixed. It’s time to consider better devices.
  4. Anti-virus: can protect you when you accidentally click on the thing you shouldn’t have and infected your system. It won’t protect against every form of infection. Windows Defender, available for all current Windows operating systems, is sufficient.
  5. Backups: I cannot stress this enough, backup, backup, backup! Many times I’m asked something similar to: ‘how can I recover my daughter’s wedding pictures from my computer’s crashed drive?’ Maybe you can, but often not. ‘I lost my phone, didn’t have cloud backup enabled, and had vacation pictures on there.’ Yea, they’re really gone. Backups serve as a way to recover from your own mistakes like accidentally deleted files and ransomware cyberattacks. A “3-2-1 backup strategy” includes 3 copies of your data, 2 on different media, 1 off-site. For most of us, this means: the original data is the 1st copy, an external hard drive (disconnected when not copying data) or network storage drive houses the 2nd copy, and a copy on a USB flash drive stored at work or backed up using a cloud backup solution – is the off-site 3rd copy.

A layered approach to security is considered best practice. As an example, creating strong passwords AND using two-factor authentication. The more layers the better, but more layers means less convenience. Brian Krebs also offers his “Tools for a Safer PC” which includes switching to OpenDNS in your home router. DNS is the service that turns human-readable URLs into IP address. OpenDNS blocks communication with known malware sites.

Hopefully this information has grabbed your attention and guided you to take steps to become safer online. Thanks for reading and 73… de Jeff – K8JTK

DSCF5081 K8JTKHey gang,

Last couple articles have been features so this month is a lot of odds-and-ends…

System Fusion

Last month’s article covering many System Fusion issues sparked some feedback as one might imagine. It was split.

One group in the section was using an external controller and was having a DR-1X repeater lock-up problem. They troubleshot the issue and with “additional circuity” resolved their issue. One disputed my assertion the repeater is two FTM-400 radios, but didn’t provide any details to the contrary. Having opened up LEARA’s DR-1X and upgraded the firmware, one radio looks exactly like the 400 (minus the speaker). Additionally, the firmware upgrade process was identical to my 400. Arguably, the transmit radio could be different but it’s hard to really tell with the heatsink mounted on top.

On the opposite end, a club in the section is completely frustrated with how Yaesu treated them as customers. They’ve attempted to call and email no less than 6 Yaesu representatives asking for details on promotions, hardware specifications, or answer to questions but never heard a word. They believe ‘Yaesu has lost any competitive edge they had by flooding the market with Fusion gear.’ Though I agree, I have not experienced this particular problem with my inquiries to support. My emails have been answered within a day or so – usually confirming suspicions I heard elsewhere. Seemingly ignoring customers is bad for business. Though customers feel they are being ignored, it may be a management attempt to better coordinate internal communication before going public. You’re doing it wrong, but it is a possibility. As pointed out previously, statements of fact made countless times are suddenly reversed and changed at release.

To clarify a point, the FTM-400 radio does operate both A & B sides of the radio simultaneously. My issue is, for their high-end offering of a mobile radio, it should be able to operate Fusion from both A & B sides of the radio at the same time. It does not. The A side can operate Fusion digital or FM. B only operates FM. Operating Fusion digital from both sides is one nice feature of the FT2D.

It didn’t take long before I started hearing the DMR arguments. DMR does have issues too but I see them as growing pains. It’s not: ‘this crashes, this locks up in transmit, this doesn’t work until you get a factory upgrade, need to spend $$$ to work around a shortcoming, upgrade to get the full power output, something can’t be fixed because there is no published specification…’ the list goes on. I’ve covered DMR issues here before and have noted most of them in my DMR Terminology and Programming a Code Plug learning series: http://www.k8jtk.org/category/amateur-radio/dmr-in-amateur-radio/.

Background checks, public service, & saving lives

The era of submitting to a background and credit check before helping out with fund-raising public service events is upon us. The local Multiple Sclerosis Society in Cleveland hosts a 150 mile (or so) bike ride every year. This used to be called “Pedal to the [Cedar] Point” but was renamed “Buckeye Breakaway” when the ride changed destinations to Ashland University. Last year, the MS society pushed for all volunteers to run a full background check. This included all ham, SAG (Support and Gear), and medical units – whether they were mobile or stationary at rest stops. Failing to complete the required check or failing the check would mean that person couldn’t volunteer or participate. This request was sprung on the ham and medical coordinators a few weeks out form the event. Citing time constraints and the amount of push back from volunteers, eventually the required check was no longer required but not after some had already completed the investigation.

This year, the MS society required a background investigation and proof of liability insurance for SAG drivers. Though I was not transporting riders, I too had to submit because I was the shadow of an MS staff person for the event. The investigation service stated a ‘credit check’ would be part of the reporting, though the society said it would not be a factor for eligibility.

Like many organizations, the MS Society is going through its share of layoffs, reorganizations, and centralization. The Cleveland chapter had little recourse since the background check was mandated from HQ. I suspect this will become the norm rather than the exception in the legal, CYA, society we live in. It sure takes the fun out of doing a public service event and not sure I want to give up that much personally identifiable information again for a fundraiser event. Then again, Equafax hands out PII data to anyone who can gain access to their systems.

That issue aside, a real life threatening event happened. Ham and medical volunteers dealt with a roll-over accident involving one of the cyclists in the event, a utility pole, and a parked car – all because of an impatient driver. This happened in Medina County near Valley City. The accident was radioed in by a ham volunteer. Other hams were on scene along with the Northeast Ohio Medical Response Corps to triage the situation. NEOMRC is a group of volunteers who provide medial support services for events and nearly all are licensed hams. The injured cyclist was life-flighted to a nearby hospital. The driver, who caused the accident, left the scene. By late afternoon, the story was all over the local news: http://fox8.com/2017/08/05/cyclist-struck-by-car-during-race-in-medina-county/. Fortunately, no one was killed. Img: Brunswick Hills Firefighters.

ISS SSTV

To commemorate the 20th anniversary of Amateur Radio on the International Space Station (ARISS), a slow scan TV event was held July 20th and ran for 3 days. During these events, SSTV transmissions originate from the International Space Station as it orbits in space. No special setup is required to copy the images. To receive the best images, Yagi antennas on a tracking tripod is best. I just use my external VHF antenna and let the radio listen for transmissions. Images sent featured different ARISS activities over the past 20 years. Check out the images 34 images I received: http://www.k8jtk.org/2017/08/03/sstv-transmissions-from-the-international-space-station-july-2017-edition/. If you want to get started in SSTV, check out the links to my getting started tutorial of MMSSTV in that post. I will also be giving my SSTV presentation at the Geauga Amateur Radio Association meeting on September 25, 2017 at 7:30 in the Geauga County Emergency Operations Center. More on the meeting: https://geaugaara.org/.

2017 Eclipse & WSPR

I contributed to the radio sciences taking place around the solar eclipse. I didn’t get to travel to an area of totality or even take off work. Instead I worked a number of the special event stations in the surrounding days. Still have to send away for my certificate. Since I didn’t take off work or do anything unusual, my contribution to the “eclipse QSO party” was to leave WSPR decoding signals and upload the spots. Scientists are hoping to learn more about eclipses and effects they have on the atmosphere and radio propagation from those spots.

WSPR stands for Weak Signal Propagation Reporting Network. If you have WSJT-X installed, WSPR is included in that package. WSPR is intended to be a QRP mode because each receive and transmit window is 2 minutes. It works like a beacon network based on timed transmissions like JT65, JT9, and FT8. Each band has 200 Hz of bandwidth designated for WSPR. A transmitting station will digitally transmit their call sign, grid square, and dBm (power output). Similar to the JT’s, the signal report (DB), time difference between the two clocks, and drift are calculated by the receiving station. Decoded signals are uploaded as spots to the WSPR Net website. The data is crunched and used to draw real-time maps of propagation. More: http://wsprnet.org/

Technical Specialist Reports

In Technical Specialist news, Dave – KD8TWG held a “Test and Tune” night for LEARA. Communications and spectrum analyzers were brought in to tune radios that might be off frequency or show how much those Baofeng radios do transmit everywhere at once. Contact Dave or a section Specialist to bring this educational and eye-opening experience to your club meeting.

In addition, KD8TWG would like to thank everyone who came out and worked the 195th Great Geauga County Fair. Dave was in charge of the communications and networking for golf cart drivers who transported fair goers to and from their cars. Golf carts were equipped with APRS for location tracking. A WiFi network based on the Mikrotik NV2 protocol was built for two weeks. NV2 is a proprietary WiFi protocol based on TDMA in the 5.1-5.8 GHz range. The advantage of TDMA wireless is better throughput and lower latency in point-to-point or point-to-multipoint networks. Traditional WiFi is built on a Carrier sensed collision avoidance system where nodes transmit only when they sense the channel is idle. Dave points out, this is NOT mesh. Over the wireless network, they ran a phone system and IP cameras. The Sherriff’s Office was impressed with the video coverage and wants to run more cameras next year. By the numbers: 60 volunteers worked 1,284 hours, with just under 700 golf cart transports. Dave ate approximately 47,000 calories in fried food. Imgs: KD8TWG.

Technical Regulation Reform

An ARNewsline report (#2080) points out the FCC Technical Advisory Council is looking for opinions and suggestions to update existing technical regulations or to adopt new ones. “The FCC wants the council to single out any rules that are obsolete or in need of being brought up-to-date. The Council also wants comments on how the agency’s regulatory process on specific technical rules could become more efficient. The agency stresses that the issues being considered are those of a technical nature.” Thoughts or opinions can be filed in ET Docket 17-215 or with the ARRL. October 30th is the deadline.

Foxhunts

I’ve only participated in two Fox Hunts. The first time, I came in dead last. Second time, came in second. No idea how that happened because no skills were honed at all. The Ham Radio 360 podcast had an episode with Larry Jacobs – WA7ZBO talking all about Fox Hunts. Surprising to me was the Tape measure antenna is very popular even among serious hunters. As for gear, an antenna, attenuator, and radio are needed. In the absence of an attenuator, your body could be used to attenuate signals. Larry talked about some dos and don’ts. He encouraged hamfests to hold hunts to ‘whet the appetite.’ The most popular hunts are races with mileage and time restrictions to keep things safe. Don’t make the hunt too hard where participants get discouraged and don’t want to ever participate again. Always use public property. Use common sense and don’t be a wise guy. For example, a convention had the fox located near the hotel pool. When someone asked what everyone was doing with antennas around the hotel, someone responded with ‘a Soviet Satellite with a radioactive payload went down near here.’ Guests couldn’t check out of the hotel fast enough. The hotel asked this group not to return. While funny, don’t be that guy. Instead have ARRL handouts and pamphlets about ham radio when someone asks.

Last Man Standing & Frequency TV shows

Many have heard by now the Tim Allen show “Last Man Standing” was canceled by ABC and possibly looking for a new home. Tim Allen plays a fictional ham radio operator using the call sign KA0XTT. The show was popular among politically conservative individuals and ham radio operators. According to ARNewsline (#2069), talks fell through for the show and it will not be returning with new episodes. The show will soon be removed from Netflix as 20th Century Fox struck a deal with Hulu for exclusive rights to their catalog, which includes Last Man Standing. Hulu is a premium service for streaming TV and moves. Channels carrying reruns include: CMT, Hallmark, Freeform, and The CW. Also on CW was the TV spinoff of the move Frequency, it too was canceled.

TYT MD-2017 Broken Antenna Connectors

If you purchased an early Tytera MD-2017 DMR dual-band radio and the antenna connector broke, contact your dealer. This appears to be a first-run issue and TYT has shipped replacement connector parts to their dealers. Replacing the connector requires opening the radio and soldering. If you’re not comfortable, ask if the dealer will do the work or swap the radio.

DSCF5081 K8JTKHey gang,

Yaesu and System Fusion. I’ve talked about it before and mentioned the DR-1X repeater promotion some time ago. My recent dealings are leaving me more disappointed in the quality of the offering. With the announcement of System Fusion II, I hope they take time to finally fix problems with their implementation.

Around the beginning of 2015, Yaesu, in an effort to get their digital mode into the ham radio market, offered a promotional deal for their Fusion repeater at a cost of $500 (~$1,700 retail). The logic behind this is the shaver and blade principal: sell the repeater for cheap and make up the cost in selling radios. The repeater is dual-mode capable (C4FM digital and analog) featuring high power (50W) transmitter, switched commercial power and battery backup, integration with an existing repeater controller, all in a standard 2U rack unit. Not only could a club or individual purchase a digital repeater for cheap, it wasn’t a requirement of the promotion to enable any of the digital Fusion features. This meant it could replace aging analog repeaters. I’ve even heard old tube repeaters were being replaced as a result. Now, I’m sure they hoped owners utilized the Fusion features but either way, the program ended up being a huge success. In the Cleveland area, there are about 10 in operation that I’m aware of. Yaesu brought affordable and a somewhat-hackable (AllStar, MMDVM) repeater package to the market.

Then came the complaints. First being the DR-1X is two FTM-400 mobile radios linked with a basic controller. For some reason, many are surprised by this setup and thought better radios should be used. This is a common design that D-STAR and DMR commercial repeaters also rely on. However, this setup had a problem; the radios used were not designed to operate high power. Either through component design or improper cooling, the radios are not capable of operating 100% duty cycle at 50W. I have not heard of this being a wide-spread problem with D-STAR and DMR repeaters running high power. Yaesu updated their promotional form and website to say “Duty cycle is 50% at 50 Watts, 100% at 20 Watts in a climate controlled environment.” To get 50 watts or more, external amplifiers are needed.

Automatic Mode Select was one of the great selling points – a single repeater could switch between digital and analog depending on the signal. But reports of repeaters in AMS where locking up in a transmit state. It was discovered when the repeater had a signal on the input (digital or analog), if another signal was detected of the opposite type, the repeater would lockup in transmit. To reset, the power had to be cycled. A work around was to set the repeater in either analog or digital only mode or install a remote power switch. To my knowledge, this was never acknowledged and was deemed to be “environmental site issues.” That might be true or related to reports of poor selectivity on the front-end of the repeater. Filters and firmware upgrades helped solve some of these issues.

Other known problems include: external controller support is complicated – at best, receive PL decode problems, repeater identifications being cut-off, and the firmware. The firmware is absurd. There are three firmware “channels” (or tracks) for the DR-1X repeater. Each completely separate and not compatible with the other – that is you cannot upgrade the repeater firmware from one channel to another. For reference, these are the 1.00b, 1.00f, and 1.10D channels. Upgrading to a newer version (on the same channel) requires taking the machine out of the cabinet, unscrew about 18 screws to access the data port inside, upgrade the firmware, and put it all back. It is nearly a two person job as the thing weights 22 lbs.

My club in Cleveland, LEARA, purchased a DR-1X. I got it on the air with some help from Bill K8SGX (a section TS). It was on the air at 20 watts in digital only mode. We didn’t have any issues. One of the club members suggested “let’s connect this to the internet.” This is where my perception of Fusion got much worse. As confirmed by Yaesu support, to directly connect an HRI-200 Wires-X node, the DR-1X must have firmware 1.10J or later. Owners with 1.00-anything firmware MUST ship the DR-1X back to Yaesu for an upgrade at owner’s expense. 22 lbs shipping plus box and insurance, it was not cheap. Specific situations may vary and return shipping is covered. They will not let you swap anything yourself because they felt upgrades where beyond most owners’ ability. Owners on the 1.10D channel just need to apply firmware upgrades.

To be fair, an RF link to the repeater can be established with any firmware version. This entails setting up a HRI-200 on a Windows PC with an additional FTM-100 or FTM-400 radio at a location with a strong signal into the repeater. This setup acts like a local user of the repeater. Transmissions from the Internet are transmitted on the repeater’s input. Local repeater transmissions are relayed to the Internet by listening to the repeater’s output frequency. LEARA decided to directly link the HRI-200 Wires-X device to the repeater. Other devices like an OpenSpot or MMDVM could be used but would not provide Wires-X access as it is a closed network.

I haven’t followed the radio issues too closely. There have been 2nd generations of two Fusion radios this far. The FT1-DR was replaced by the FT1-XDR and FTM-400 by the FTM-400XDR because the GPS chip used had problems locking on to signals. I have the FTM-400XDR and picked up a FT2DR at Dayton. Both radios work and get the job done but I’m not blown away by either radio. To put the 400 over the top, it would need to operate Fusion from both A & B sides of the radio, at the same time. I’m underwhelmed by the FT2 screen as it’s not very sharp. I’ve always found Yaesu menu groupings and labeling confusing. The much-loved bank link feature of their analog radios, such as the VX-8, is missing.

Word of warning to anyone using Yaesu Fusion radios and is especially important for repeater owners and Wires-X node operators, keep up-to-date with firmware and program updates! It has been confirmed in the Yahoo Group, every time an FT-70 radio is keyed on a Wires-X node with software version v1.2 or earlier, the Wires-X node will crash.

In addition to all these issues, no full specification has been released for Fusion or Wires-X. Meaning if Wires-X gets shutdown, all nodes are offline. With an open source specification, a new network could be developed or rolled into the FCS reflector or YSFReflector networks. In true hacker fashion, much of Fusion has been reverse engineered so it’s probably more of a reality than I know.

A Reddit posting appeared proclaiming “System Fusion II” is coming with an accompanying info graphic and FAQ posted on the Yaesu System Fusion Yahoo Group. The info graphic states ‘firmware upgrades will enable System Fusion II compatibility with all existing C4FM products.’ I gather this doesn’t mean the radio needs to be sent back to Yaesu. The FT1-(X)DR is discontinued but the FAQ reiterates all existing radios will receive a Fusion II firmware upgrade.

At the center is the new DR-2X repeater – which supposedly resolves most problems of the 1X – and includes many new features. Originally, Wires-X was not supported at all on the DR-2X. This was stated many times by Yaesu. The FAQ indicates the 2X will support the HRI-200 (direct connect) OR IMRS (Internet Multi-site Repeater link) option. It will not support both. The IMRS option sounds a lot like DMR IP Site Connect where repeaters are linked over the Internet using Talk group-like functionality. There is another promotional program offering a trade-in path from a DR-1X to a DR-2X for $300 without the site linking option and $500 with site linking. See the Yahoo Group as I don’t see this promotion information anywhere else.

DSQ (Digital Squelch, squelch code) is replaced by DG-ID (digital group ID). DSQ has caused controversy even locally because it is a global setting in the radio, not per channel. This is a real pain if two repeaters in the area choose different DSQ codes. I left it disabled on LEARA’s allowing any Fusion user to use the repeater. A DG-ID use-case example on a repeater: use the repeater locally might be DG-ID 71. To use two IMRS sites might be DG-ID 90, and all sites DG-ID 99. A DP-ID is a priority override or used for remote control of the system on the 2X only.

Fusion up to this point seems rushed, untested, and like most companies today, driven by marketing. The mentality being: ‘get it out now, fix it later.’ I really hope Yaesu gets their act together soon if they want Fusion to survive. This will likely require drastic business and management changes within the company. As I see it, Fusion survival requires fixing its perception, fixing the software issues, producing better quality devices/radios including extensive testing, and showing commitment to the community and developers by releasing protocol specifications or open-sourcing the technology.

DSCF5081 K8JTKHey gang,

Have you recently built something? Came up with a solution to a problem in the shack? Achieved a milestone? Now, ask your club newsletter editor if they are looking for content from club members. I’ll bet they say “yes!” Hams are interested in good articles written by club members sharing their experiences with projects and adventures. You’ll be surprised to find out how many other people are interested in the same thing or how it will motivate others to experiment with something similar. Believe me, it happens. One of the reasons you see me here in the OSJ is because of articles Ken – KG8DN asked me to write for the LEARA newsletter a few years ago. If you don’t write articles as part of a job or for fun, the last time many of us wrote anything was probably in school. Those writing technique brain cells were fried long ago. I will cover techniques, ideas, and some lessons learned to assist you in putting together a fantastic article for the club’s newsletter.

First and most important, meet with the newsletter editor or shoot them an email letting them know the topic you want to write about and get an idea of their requirements. Requirements such as: how much space will I have, will there be room for pictures and diagrams, when is the deadline to have everything turned in. Page requirements will help you focus the article emphasizing certain topics and provide detail versus insignificant points that don’t fit with the rest of the story. The editor may have some general questions to help jump-start the process. This works too as stories wrote themselves with a question or three. Note these questions and refer back to them if you have writer’s block. If the topic isn’t exactly ham related or different than the usual type of articles found in the newsletter (ie: more public service than technical), ask about that too or write it with a technical focus.

With the editors’ requirements in mind, make an outline (bullet point list) of general topics to cover. What do you see as the major milestones of the project? Maybe something like: design considerations, building, and operating. Once the main points are established, include a few detail points. For a build project, this might look something like:

  • Design
    • Power source (AC, DC, USB, car, battery)
    • Inputs (radio audio, computer audio)
    • Outputs (radio audio, computer audio, line monitor)
    • Connections (speakers, headphones, USB)
    • Indicators (LED: power, audio level, PTT)
  • Build
    • Placement of components (circuit board, level adjustments mounted on the side)
    • Connectors (USB, serial, audio)
    • Sizes (hidden switch, large lighted switch, large LEDs)
    • Housing (Altoids tin, wooden box, oil pan, baking tray, hobby store find)
    • Mounting (wall, portable, back of radio)
  • Operation
    • Testing (digital net, friend over the radio)
    • Tweaking (changed component values)
    • Adjustments (audio level knobs in front, manual pot inside)
    • Anticipated results (clean audio on PSK)
    • Actual results (splattered across the entire band – only kidding)

After the general outline is assembled, it’s time to start thinking about the details. People have different writing styles. Some plan the entire article top to bottom and write as such. Others start with the detail points and form a story around it. Some just write their stream-of-consciousness then add or delete details in revisions. Whatever your style, introductory paragraph should have generalizations about the topic giving the reader something they can relate to: “have you ever heard…,” “did you ever wonder about…,” “I first learned about…,” “while I was doing X, I heard about Y,” “when I first got my license I was thinking what about doing Z.” The first paragraph or two should illustrate the topic in “broad brush strokes.” No specific details about the topic, yet. Quaky antidotes are always good. The last sentence should setup the specific topics covered in the article. This is referred to as the thesis. The thesis can outline specific topics: “I’m going to talk about experiences designing, building, and operating my new widget.” Or general: “here’s how I got this project off-the-ground” with specific topics detailed in the article. Either way, the main bullet points created earlier should form the thesis and drive the main topics covered in the article.

After topics are established for the reader, start by first talking about the problem you were trying to solve. Talk about things like: “I wanted to add JT65 capability to my QRP rig,” “I’ve used available interfaces before and wanted mine to do A and B because C,” “I wanted to learn Linux so I used a Raspberry Pi to make a portable NBEMS station,” “I wanted to learn Python and now the club’s station can be operated remotely.” Fill in the details about how you went from a problem to a working solution using the detail bullet points outlined earlier as a guide. Was the solution similar to another design found online or did you create one from scratch? Why did this solution work for you? What value did it add for you? What lessons did you learn about your chosen path? What problems did you incur and how did you solve them? Describe to the reader the functions of different pieces or purposes of the different stages. Example: “this stage takes the audio from the radio and amplifies the level for the computer,” “this takes the computer audio and drops the level for the radio.” When in doubt, answer the 5Ws: who, what, when, where, why.

It’s incredibly easy to get wrapped up or focused on the details. Remember your reader probably doesn’t have the same level of experience and is only mildly interested in your project. Bombard them with minute details and their head will explode. Give them some table scraps, they’ll find something interesting and keep reading. Don’t rattle off specifications like: ‘I choose the ARM v5 blah blah processor because flux capacitor blahs blahs +1,000,000,000V than the equivalent direct-conversion Arduino ATmega2560 16 MHz blah blah PWM at 4097 bit encryption…’ No one cares. Concise descriptions in (mostly) plan English are always better: “I wanted an audio path between the radio and computer that keyed the transmitter from the software. It must be isolated to prevent buzzing and hum noises from potential ground loops.” Most hams know what those terms mean. If some technical detail is paramount to the story, relate it to something most non-technical hams would understand: “the Raspberry Pi hard drive is an SD card, which is the same type of storage used in nearly all cell phones and digital cameras.”

If space allows, note any other solutions researched and discuss reasons those alternative methods where abandoned. Take a position then argue with yourself: here’s my idea, here were other possible solutions and why I didn’t accept them or why they didn’t work. An absence of supporting facts shows a lack of critical thinking and understanding of the subject. The closer the audience is to a subject, more convincing and disproving other theories will be required. Use of snarky comments shows arrogance, so leave them out.

Finally, wrap it up. Include anecdotes, accomplishments, funny stores, or final comments about the project. Were you happy with the results? What do you use the device for? Did you find other or different uses for the project than you envisioned?

Pheew! Now I’m done right? Well, far from it. The article is written, now revise, revise, and revise. Re-read your work to make spelling, grammar, and context corrections all while making sure it flows well together – does anything I wrote make sense? The free LibreOffice Writer is great but Microsoft Word has a phenomenally better grammar checker. For me, it works best to print the entire article, read it, make revisions on paper as I go along, enter them into the computer, print it out again, make more revisions, put it down for a few days – repeating this process about 5 or 6 times. Printing takes me away from the computer allowing me to focus on the article. I picked up this habit in grad school when I got a C on a paper. I knew if I spent more time revising, my grade could have been better. Whether I’m not in the right mindset, got a lot going on, stressed, or not committed, my revision regiment eventually produces something I’m proud of. If you’re not good with revising, ask a buddy or spouse to help you out.

The newsletter editor is there to give you some direction. Don’t expect them to do all the work. They have enough to do. Unlike news or publishing organizations that have paid staff to scrutinize the article, the editor probably has little experience or standing with your topic. If they offer to proof read and make suggestions or comments, utilize it. Don’t expect them to validate every detail, statement, correct every spelling mistake or grammar error. Don’t take offense to their feedback either. They’re trying to help by providing constructive criticism while making the newsletter appealing to readers. Don’t send them a bunch of pictures without relating them to the work. It will be embarrassing when they put the wrong picture in the wrong section because ya didn’t make it clear!

For images, designs, or facts found elsewhere, give credit to the source of that information. You wouldn’t like it if someone stole your design and claimed it as theirs. In school, they made this big deal about using specific style guides for a bibliography. I haven’t used any of that stuff. I’ll make a note, usually with a website or URL, in line with the text or put a section at the end giving credit for their hard work.

Personally, I love to see pictures of the device in operation, installed, or the person working on it. Leave out anything more than basic diagrams and schematics. Details in those images will be lost when sized for the copy. Detailed images, documents, diagrams, and videos can be uploaded to a website, if available, or use a free online storage service like Google Drive or Dropbox. Both have provisions to create a shared directory that others can only view (that is important!). Link to that folder or specific file at the end of the article: “for more pictures, a more detailed write-up, or schematics, go to this URL.” Videos are good if they’re kept to about 2-4 minutes in length showing the person using their project and talking a little about it. These can be uploaded to YouTube for exposure or to the online storage folder. Longer detailed videos or build videos should be separate. If the viewer wants to learn more, they can check-out the longer versions.

While the examples provided here were geared toward a build project, this outline can be used for sharing knowledge on a software defined radio dongle you picked up, a new digital mode you learned, operating adventure, or new toy many have yet to see. If you’re still looking for more methodology ideas, grab any issue of QST and follow the format of a similar article to yours. With a little work, you can become a published author and help your club out in the process!

DSCF5081 K8JTKHey gang,

Another Dayton Hamvention is in the books. Yes, despite the arguments – ‘it’s not in Dayton anymore blah blah blah’ – the program guide still says “Dayton Hamvention.”

My dad, N8ETP and I have been attending Hamvention consecutively for the past 3 years. I’ve gone down a couple years by myself, stayed at numerous hotels in the area, bummed rides off friends, taken bus trips, and even stayed at the dorms on the University of Dayton’s campus. Returning back each year quickly brings back memories of routes in and out of the arena along with familiar eating and travel destinations. The layout inside rarely changed. You knew where the prize booth was located along with favorite dealers, vendors, clubs and organizations. The entire back parking lot was the flea market. There was the usual selection of arena eats – burgers, nachos, hot dogs, pizza, and ice cream – that often benefited a local school or community organization.

Now, everything is different.

The Hamvention committee should be commended for the monumental task of moving the event from the now closed Hara Arena to the Greene County Fair Grounds in Xenia, Ohio within 9 months. I can’t even imagine what it takes to setup an event that draws 25-30,000 people let alone move it to another location quickly.

Buildings at the new location are less than 20 years old. They were rebuilt after a tornado hit the fairgrounds in 2000. RV parking and an on-site bathhouse were available. There was ample parking on the grounds and at three remote locations with shuttle transportation. Quite different compared to the dilapidated arena where there always seemed to be a haze indoors due to the lack of air flow, falling ceiling tiles with mold and probably 30-year-old dust, and septic system with a propensity to explode.

Atmosphere of was more “fair” than “convention” because vendors and exhibitors were spread out over separated buildings (themed Maxim, Tesla, Marconi, and Hertz), displays were in outside tents, and an abundance of food trucks and carts similar to that of any county fair was seen. More eating area was needed compared to the amount we were used to at Hara. There were long lines and the limited seating, for maybe 50, filled quickly. I had an enjoyable standing lunch with members of the Wood County ARC.

If you were lucky enough to be there Friday, you were greeted by the “Welcome to Xenia” signs quickly followed by break lights and miles of cars waiting to get into the fairgrounds. Even the shuttles were stuck in traffic. The reason was discovered once we arrived. Cars were being parked at a rate of nearly one-at-a-time. Time was wasted waiting to see which isles were full and which ones had room for additional cars. This was quickly remedied Saturday as cars were being parked in multiple locations at once, effectively eliminating the traffic issue from Friday. Scratch that issue off the list.

In general, Hamvention is smaller. I knew this going in from vendors indicating they weren’t going to have the space they were used to. Vendors made the most of it and generally seemed to work. As a result, vendors couldn’t bring the usual amount of stock. Show specials for things like the very popular TYT MD-380, you could purchase one but couldn’t leave with one. In one case, it would be shipped and arrive the following Tuesday. Kinda a bummer as many hoped to leave with a new toy. Vendors in the outside display tent got washed out with storms that rolled through. Not good for computers, sensitive radio equipment, and video cameras I saw out there. I was not able to find Mendelsons – a long time staple of the Hara flea market. I heard others asking too if they had been spotted.

Lastly, mud. The flea market and parking lots were in grassy areas, or at least started out that way. Friday wasn’t bad as the ground was soft in a few areas of the flea market. Saturday morning, with the help of overnight storms, large farm tractors used for transporting patrons were contributing to the problem of turning the grassy parking lot into a mud pit. After everyone took shelter for even more storms Saturday morning, allll bets were off. The flea market isles were mud tracks. A good pair of rain boots were needed to help manage. It was funny watching rented scooters trying to manage a couple inches of mud. Not wanting to get our clothes dirty, we headed out about 3pm on Saturday and learned the parking lot suffered the same fate as the flea market. The committee, I think, anticipated this because they had rope and skid loaders for cars that needed assistance. We exited without assistance but still need to get our car washed twice to get MOST of the mud off.

All-in-all, I’ll call it a success. Out of the things that could go wrong, these issues were the harder ones to plan and tackle. The traffic issue was resolved the next day. This shows they are already learning from the problems that came up during the show. It was a suitable location for a venue change in 9 months. Anyone who is thinking of going next year, you should make your reservations now. The camaraderie, meet and greets, and running into fellow hams was as exciting as ever. If any of the planning committee is reading, I have an idea for a bigger location… just sayin’.

If you didn’t catch the June 7th episode of Ham Nation, Michael Kalter – W8CI was the featured guest for the Hamvention recap. They talked issues and plans for the future. If you think they’re only working on minor changes, you’d be wrong. More: https://twit.tv/shows/ham-nation/episodes/303

There wasn’t a ton of major announcements at Hamvention. Some of the more technical things I did pick up on:

  • ICOM had a prototype of their latest direct-sampling SDR transceiver, the IC-7610. It resembles the IC-7600 with the SDR features of the IC-7300. They’re looking at late summer availability once approved by the FCC.
  • Kenwood featured their TH-D74 APRS & D-STAR 144/220/430 HT. This radio has been out for some time but were touting D-STAR has seen a resurgence because of this radio. I don’t think people are going to start putting up D-STAR repeaters again because of one radio. Kenwood is looking for feedback from customers to see if there is interest creating an equivalent mobile radio to the D74.
  • 220 MHz DV access point (DVAP) for the D74 and 4 new “DV AIR” devices by Robin AA4RC. AIR series are embedded devices supporting the DV Dongle, DV3K, and DVAP eliminating the configuration and need of a Raspberry Pi to make those devices portable.
  • Yaesu had their new DR-2X repeater on display.
  • Flex Radio has four new SDR radios. Two models integrate the Maestro control panel (touch screen and controls) into the radio. If you ever thought ‘real radios have knobs,’ there you go.
  • Just before Dayton, Connect Systems shipped the first batch of CS800D DMR dual band mobile radios. There is a waiting list for the next around assuming no issues with the first. Check the Connect Systems store and look for the ‘CS800D waiting list’ option for instructions.

The 300th episode of Ham Nation was the week before Dayton. I attended the Ham Nation forum which was still standing room only in the new room. I got to be apart of the forum promoting the D-STAR After Show net. Show hosts and net controllers were invited to the ARRL booth afterward to get our picture taken with Tom Gallagher – NY2RF.

With the highlights and festivities around Dayton Hamvention, the special event commemorating 300 episodes of Ham Nation kicked off the following Wednesday with episode 301. For one week, show hosts, after show net controllers, many with 1 x 1 special event call signs where on the HF bands and digital modes. With nearly an estimated 10,000 contacts made, digital didn’t get the numbers we hoped. There were pileups for the nets but quickly dropped off for the remainder of the week. The idea for digital was to involve more hams that don’t have privileges or means for an HF setup. Those that participated were happy digital was involved.

If you participated in Ham Nation 300, send your QSL card with an SASE to the stations worked. A commemorative card will be returned. The logs are being compiled for the certificates which will be available in the future, catch the show for details. Lastly, the points challenge is going on until August so you still have time to get involved if you missed the special event stations.

Last month, I started out with an introductory series on terminology used in ham radio DMR. I finished a second writeup on programming a code plug from scratch. Programming is focused around the TYT MD-380 but should apply to other CPSes too. It covers a fictitious repeater example, hotspot configuration (even for the DV4Mini), and simplex operation. Check it out and get familiar with your DMR radio by programming it! http://www.k8jtk.org/2017/06/11/dmr-in-amateur-radio-programming-a-code-plug/

Not at Dayton but shortly after, I saw a hands-on review of the new Tytera (TYT) MD-2017 DMR dual band hand held on Ham Radio 2.0. You heard right, a DUAL BAND DMR HT! I was excited for this radio even though there are not many VHF DMR repeaters – unless you’re in New England it seems. The review indicated the channel selector knob was replaced with a Blackberry Curve-style roller trackball. My enthusiasm quickly deflated. WHY??!! I had a BB Curve. The trackball was a nice idea at the time but it was overly sensitive, got gummed up quickly – especially in a dirty environment, was hard to clean, and had to be replaced about once a year. The radio itself is similar to the MD-380 but differences include programming cable, software, code plugs, and a VFO. An MD-380 code plug won’t open in the MD-2017 CPS. I’m sure a hacked program will be available to load code plugs on different radios. Seemed like a good radio otherwise, though I won’t be getting one.

The next big ham holiday, Field Day, is right around the corner. Get out and join your club or find a club to join if you’re not a member of one. It’s a great time to bring friends and get them excited about ham radio. Hams that come out get bitten by the bug to expand their station or learn a new mode. Check the Field Day Locator for operations taking place near you: http://www.arrl.org/field-day-locator. Sending 10 messages over RF from your site gets you 100 points – including Winlink messages. I love to receive messages about your setup, stations operating, or social activities taking place. These can be sent via the National Traffic System (NTS) or Winlink – K8JTK at Winlink.org. Winlink post: https://winlink.org/content/field_day_send_11_winlink_messages_200_points

With July around the corner, the 13 Colonies special event is coming up (http://www.13colonies.net/) along with the RAC Canada Day contest (http://wp.rac.ca/rac-canada-day-contest-rules-2017/).

DSCF5081 K8JTKHey gang,

DMR: you’re hearing a ton about it from the Ohio Section and the number of repeaters has exploded with nearly 60 in the state. DMR saw growth due to inexpensive offerings of quality radios at last year’s show. I suspect this year will be no different with new offerings from vendors, possibility of dual band radios around the corner, and many more groups supporting DMR.

How many of you know the terminology and could program a DMR radio from scratch? Passing around a code plug makes the mode seem plug-and-play and it’s a great way to get started. Relying on existing code plugs leaves most of us unable to change the configuration of our own radios or even know how it works. What happens if you need to change programming, add a repeater, the code plug information is old, or wrong?

When I started last year, I found there was very little information available on DMR in ham radio. I learned DMR by doing a couple things. First, I looked at the code plug I downloaded for my TYT MD-380. I got a lot of knowledge playing around with that. There were a couple things I wasn’t quite sure about. When I got together with a buddy who was interested in DMR, we further played around with the software, tried different settings, and I filled in those gaps.

With the continued support from the Ohio Section, one of our Technical Specialists, Dave – KD8TWG has been giving training presentations on radio programming and he created a DMR Learning Series explaining terminology and etiquette: https://kd8twg.net/category/dmr/dmr-learning-series/.

I put together a paper with the goal of explaining DMR to the person just starting out and include some more technical descriptions. It started as an idea to write an article or two for the OSJ around Dayton time so anyone jumping in would have good information. After starting the project, it quickly became much bigger.

The first writing talks about the DMR standard and compares it to other made-for-ham-radio modes like D-STAR and Fusion. One topic that might be of interest is the section on ‘is it legal?’ I’ve heard this question come up frequently and even clubs in the section are questioning the legality. Radios, CPS, code plugs, registering for a DMR ID are all discussed. I talk about repeaters, c-Bridges, networks, and some of the issues one might encounter. Terminology covered includes time slots, talk groups, reflectors, contacts, RX Group Lists, channels, zones, scan lists, and hotspots: http://www.k8jtk.org/2017/05/10/dmr-in-amateur-radio-terminology/.

The second will deal with creating a sample code plug for a factitious repeater, tying all the terminology together. Afterwards, you will be able to create and update your own code plugs! Stay tuned to next month. DMR repeaters in Ohio: https://www.repeaterbook.com/repeaters/feature_search.php?state_id=39&type=DMR.

At the request of Cuyahoga County Skywarn, Technical Specialist Dave – KD8TWG has installed a Sage EAS ENDEC device on the 146.76 repeater in Cleveland. 146.76 is the primary Skywarn repeater for Cuyahoga County. The device is the same used by radio and television stations to broadcast Emergency Alert System messages. It monitors NOAA weather radio frequencies and broadcasts tornado watches/warnings, thunderstorm watches/warnings – for Cuyahoga County, and the weekly EAS test. It’s been performing flawlessly!

The data and attention tones are the same everyone is familiar with. These are the same one would hear tuning to a broadcast radio or TV station during an event. In order to not clobber an existing QSO, the device will delay playing the alert until the repeater is free. DTMF tones are available to Skywarn NCS’s to disable the alerts if it begins to interfere with the net. Some innovative working being done here. Thanks for the hard work Dave.

Anthony – K8ZT, our ASM for Educational Outreach, shared some links with me from his site. He has put together lists of great resources for doing projects, ideas for the class room, training classes, and build projects a group my want to coordinate:

After my write up of podcasts last May (http://www.k8jtk.org/2016/05/15/ohio-section-journal-the-technical-coordinator-may-2016-edition/), I try to catch ones that feature a ham in the Ohio section. QSO Today episode 144 featured John Ackermann – N8UR. John was a past president of TAPR (which I’m a member) and is a big proponent of open source hardware and software (openly sharing designs that make the community better). Eric and John talked about his usage of SDR radios and this collection of test equipment. He’s done alot of experimenting with APRS and shares some of his lessons learned. I especially liked his idea that hams can achieve much greater data transfer speeds in the 3 GHz portion of our spectrum. Maybe others in the section will develop technology to utilize that spectrum more than we are currently. The podcast is available on your favorite podcast app by searching for “QSO Today” or by going to: http://www.qsotoday.com/podcasts/n8ur.

Don’t forget #HamNation300 special event is starting the Wednesday following Dayton. There will be stations operating D-STAR, DMR, Echolink, possibly Fusion, P25 and anything else we can get our hands on – in addition to SSB. I will be doing D-STAR, JT65, and maybe PSK too for some HF digital contacts. Points challenge is available for those who enjoy the social aspect of a special event. Tune in to Ham Nation (twit.tv/hn) every Wednesday evening. Details can be found on our event page: https://www.hamnationdstar.net/2017/04/05/ham-nation-300-special-event/. I will also be participating in the Ham Nation forum at Hamvention on Saturday, 10:30a in Room 1.

The show featured the digital net controllers this past Wednesday (5/10). My ugly mug was featured along with my good friend Andrew- WA8LIV from the DMR net and Dave – N3NTV from the Echolink net. You can watch the segment if you dare: https://youtu.be/afWX5kQSBAg?t=1h11m27s or download it at: https://twit.tv/shows/ham-nation/episodes/299. There’s a reason (more than one?) I stayed behind the camera when I worked TV production. I kid, check it out and join in the fun of #HamNation300.

That’s about it for this month. I’m looking forward to meeting all of you at Dayton (er, Xenia) this year. I’ve heard there were a record number of ticket pre-orders which I hope means a successful year for Hamvention. One thing I can guarantee for this year: it will be different for all of us. I’m excited to see what’s in store at this new venue. Get your shopping lists ready…. and see you at Dayton! Thanks for reading and 73… de Jeff – K8JTK

DSCF5081 K8JTKHey gang,

Since the last couple months have been feature articles, this month will be odds-n-ends.

Maker Spaces & Faires

I got positive comments on last month’s article about Makerspaces and Maker Faires. I hope it gave clubs and groups ideas to get younger makers into our hobby. Not only did the January edition of QST have the article on Maker Faires but it was the focus of ARRL CEO Tom Gallagher – NY2RF’s note in April. I’m happy to say these types of things are on the radar of the League and they’re focusing efforts on this new generation of Ham Radio operators. According to Tom, the ARRL plans to be at the three national maker events this year.

AllStar

I learned the creator of AllStar Link, Jim Dixon – WB6NIL, passed away at the end of last year. Jim is the creator of “app_rpt” which allowed the open source PBX system, Asterisk, to function as a repeater controller. In doing so, created one of the most impressive and versatile solutions for VoIP (Voice over Internet Protocol) in ham radio. Having played around with AllStar on my own node, nodes can be linked together directly through the public Internet, private network, point-to-point network, or really any combination of methods. Hubs are systems with greater bandwidth allowing for multiple simultaneous connections – like “reflectors” on IRLP or “conferences” on Echolink. One of my buddies who spoke with Jim commented that he was the smartest, nicest guy you’d meet and [he] would be doing well if he retained even half of what they talked about. Jim will be missed but the AllStar project will live on. AllStar Link: https://allstarlink.org/, Raspberry Pi & BeagleBone image: https://hamvoip.org/

Fldigi & Flmsg

W1HKJ and the contributors to the Fldigi project have been busy (http://www.w1hkj.com/). A new major release of Fldigi was made available at the end of March. This brings both Fldigi & Flmsg up to version 4.0.1. Technical Specialist Bob – K8MD messaged me about the update. My response: ‘crap, I just updated the screen shots from the previous changes the weekend before’ (3.22.x). I was hoping there were no new changes. Of course there were! Now my newly updated instructions are dated again! Those instructions were getting stale because of significant program option changes since I made them available about two years ago. They are on my site (up to Fldigi v3.23.21 and Flmsg 4.0.1) at http://www.k8jtk.org/2015/04/16/getting-started-with-fldigi-including-flmsg-and-flwrap/. Written for the LEARA Digital Net, they do focus on NBEMS operation.

Check them out and do some practice nets. From experience, it’s best if ALL participating stations are using the same program versions. There are fewer issues with forms because newer forms are included in later Flmsg versions that were not in earlier ones and everyone can be on the same page when going through settings.

Over that same weekend, I wrote up tutorials and hacks you can do with Flmsg. We’ve all been there. You missed receiving part of an Flmsg message because of being off frequency (radio or waterfall), in the wrong mode, or not paying attention. The issue is quickly corrected and most of the message is still received. However, Fldigi doesn’t know what to do with the form because some of the headers are missing. When headers are missed, Fldigi can’t open the form because the message won’t checksum. The checksum is used to verify the entire message was received. I wrote up a tutorial how to recover a partially missed message: http://www.k8jtk.org/2017/03/25/recovering-a-partially-received-flmsg-message/.

The last is more of an Flmsg hack. When an Flmsg form is received, NBEMS standard is to have the ‘open in browser’ option enabled. As expected, this will open the received form in the default browser. Many don’t realize that any web programming code (HTML, CSS, JavaScript) sent as part of the form will be interpreted by the browser. This means you can send clickable links, link to an image, redirect to websites, and change background colors. Just about anything that can be done on a webpage can be sent as part of an Flmsg form and rendered when opened in the browser. Find out how at http://www.k8jtk.org/2017/03/25/flmsg-forms-rendered-as-web-pages/. Standard squid disclaimer for both: this is for fun and not NBEMS compliant.

OpenSpot

If you have an OpenSpot hotspot, there was a major firmware update for the device in February and subsequent update in March to bring the current version to 108. The changelong has – in the neighborhood of – 80 (yes, eighty) fixes and enhancements. Previously, I wasn’t using this device to run the Ham Nation D-STAR After Show net. However, since they added a nice web interface with call log and export feature, it’s now my device for running the net. If you’re looking for a ham radio digital mode hotspot, check out the SharkRF OpenSpot: https://www.sharkrf.com/products/openspot/

One of the SharkRF connector options is their own IP Connector Protocol Server (https://github.com/sharkrf/srf-ip-conn-srv). The Connector Server is used to create a network of OpenSpot devices and it can be implemented in other hardware/software as it is open source. Like AllStar, it can accept public internet connections, run on a private network, or mesh network. I haven’t tried but it may even compile and run on a Raspberry Pi.

The Connector Server repeats any digital transmission sent to it. All modes can even be simultaneously connected. D-STAR connected clients will only hear D-STAR transmissions because there is no transcoding of D-STAR data streams. DMR and Fusion streams can be transcoded. DMR streams are transmitted to modems set to DMR and converted by the OpenSpot to Fusion for Fusion modems. Similarly, a Fusion stream is transmitted to modems sent to Fusion and converted to DMR for DMR modems.

I’ve setup a Connector Server that is open and there to mess around with. In the OpenSpot configuration:

  • In Connectors: under Edit Connector, select “SharkRF IP Connector Client.”
  • Click “Switch to selected.”
  • Once changed, enter your TX/RX frequencies.
  • Server address: srf-ip-conn-srv.k8jtk.org
  • Port number is in ‘Advanced mode’ but is the default, 65100.
  • ID, use your CCS7 DMR ID.
  • No password.
  • Enter your Callsign.
  • Click “Save.”
  • In the Modem options, select the desired mode.

The dashboard is: http://srf-ip-conn-srv.k8jtk.org/. The server will remain online if it continues to see use. Otherwise, it could disappear at any time without use 🙂

Ham Nation 300 (#HamNation300)

Last but certainly not least, yours truly has been on the planning committee for the Ham Nation 300th special event. Ham Nation is an audio and video podcast recorded live and available at https://twit.tv/shows/ham-nation. The program records at 9:00 p.m. eastern time every Wednesday evening. Following each episode are the “after show nets” which are round tables discussing the show or ham radio. These nets include: 20m, 40m, D-STAR, DMR, and Echolink.

After each 100 episodes, a special event is planned to commemorate another 100 episodes. In the past, these have been geared around HF. The show is not only for the General/Extra class licensees and not everyone has the ability or desire to operate HF. This year’s festivities have something for everyone including the chance to make digital contacts for the special event and a summer long challenge.

Ham Nation 300th special event runs the week following Dayton, May 24-31, 2017. Full details can be found on any of the 1×1 special event callsigns on QRZ or at https://www.hamnationdstar.net/2017/04/05/ham-nation-300-special-event/. Please join in and help make this event successful. Follow it on social media: https://twitter.com/hashtag/hamnation300 and https://www.facebook.com/HNonTwit.

That’s about it for this month. Thanks for reading and 73… de Jeff – K8JTK

Jeff Kopcak – TC

DSCF5081 K8JTKHey Gang,

Ever heard of a makerspace? I hadn’t until one of the podcasts I follow, Hak5, talked about the concept and visited a couple. Following that, the “QSO Today” podcast (episode 75) talked about a connection to ham radio and the January 2017 edition of QST gave ideas for clubs participating in “Maker Faires.” Makerspaces, sometimes referred to as hackerspaces, hackspaces, or fablabs are shared resources for creative DIY types where people can gather to create, invent, and learn. Sound familiar? It should. Those are the foundations of Amateur Radio.

“These spaces combine manufacturing equipment, community, and education for the purposes of enabling community members to design, prototype and create manufactured works that wouldn’t be possible to create with the resources available to individuals working alone” states makerspace.com. Makerspaces are a relatively new idea with a leaning toward younger individuals. Spaces can be setup by a group of individuals, nonprofit company, or for-profit company who host spaces in rented buildings, schools, universities, libraries, or anywhere else the community decides to meet.

The business model is similar to that of a gym membership where users of the space pay a monthly membership fee – somewhere in the neighborhood of $30-$50. This gives members access to the facility and its resources. Those resources may include: machine shop, wood shop, welding shop, electronics lab, 3D printer, laser engraver, art supplies, blacksmithing, molding and casting, robotics lab, CAD software, glass blowing, space for experiments, and even entrepreneurship classes. The possibilities are endless. This model works because purchasing even one piece of equipment will run an individual more than the cost of a membership fee. Experts and instructors are available to help others learn how to use the equipment – on-site or through training classes.

When you think about it, hams have been doing this for decades: borrowing radios, borrowing test equipment, and pulling knowledge from the larger community to accomplish a task. The community, as a whole, is a much more powerful resource when each individual shares their own knowledge with the community and builds encouragement for others. Look at all the aspects of the ham radio hobby. Some hams are good at soldering, surface mount, climbing towers, programming, tuning repeaters, fabrication, digital operation, software defined radios, Internet linking, portable operation, award chasing, DX, CW, QRP, building antennas – no one ham can do it all. It’s the reason most of us join clubs. Contribute to the community and learn from others.

Getting ham clubs affiliated with makerspaces will promote the maker mentality of ham radio in a space where people who make stuff are already gathering. A club could hold licensing classes or a build project in the space. Others would see those sessions posted around the space, promoted on the website or Facebook group, or in an email to the makerspace members and community inviting others to join in. One club in our section is doing just that. The Wood County Amateur Radio Club has partnered with the BiG Fab Lab in Bowling Green, Ohio. I am a Life member of the WCARC and joined this club while attending BGSU in 2002.

About the BiG Fab Lab from their website:
BiG Fab Lab, LLC is an open-access 24/7 workshop (or “Maker Space”) that serves people in the Northwest Ohio region. We provide the equipment, classes, private storage and studio space, and personal assistance to a membership community that allows them to prototype and develop any idea they can imagine. We are targeting people, schools, and businesses who have an interest in hands-on skills in a variety of crafting, design, manufacturing areas, and business incubation. We also provide retail space so that our members can test market and sell their creations! … Could you imagine the power of bringing business, students (K-12 & university), and community members together into one place? No walls, no silos, each sharing and collaborating with others to innovate, educate, and collaborate. Perhaps we could transform our region and maybe the world!

Located in the Woodland Mall off North Main Street, the $40 membership fee gives access to: a wood shop, machine shop, engravers, 3D printers, plotters, laser engravers, an arts and crafts space for ceramics, large cafeteria style meeting room, and they’re not done yet! Training classes are held for each piece of equipment in the lab. Once a member is trained and demonstrates the ability to safely operate the equipment, an achievement is added to their member swipe-card giving them access to that equipment 24/7.

The BiG Fab Lab will be featured in an episode of the PBS show “The American Woodshop.” Scott Phillips, host of The American Woodshop, and the crew from WBGU-TV (a former employer of mine), taped episode 2409 set to air this month (March 2017). If you missed the show or it’s not carried by your local PBS station, past episodes can be found at http://www.wbgu.org/americanwoodshop/ and look for “Watch Episodes” near the bottom.

In one of my return trips to visit the club, I got a tour from Bob Boughton – N1RB and Bob Willman – WB8NQW to see how this partnership came to be. Mark Bowlus, Founder and Director of the BiG Fab Lab, wanted to strengthen the presence of electronics in the lab. Doing some research, he reached out to the Wood County Amateur Radio Club. Over the past few years, the two have partnered and are developing a relationship promoting electronics and ham radio. The club established a station at the Fab Lab which and will include VHF/UHF station and HF station. Of course, the work is never done and more is being added all the time.

WCARC couldn’t be happier about the cooperation they are receiving from the Fab Lab. To date, there have been two ham radio licensing classes; one Technician and one General. A second Technician class was started in February of this year. The turnout has been better than expected because the BiG Fab Lab is promoting these classes on their calendar and Facebook group. Participants come as far away as Michigan. Students are charged $30 for the training manual, exam fee, and a monetary fee charged by the lab to use the space.

Future plans include building out the electronics area with test equipment. The club hopes to offer regular electronics and license training classes. Once the training classes are in place, the Fab Lab has offered to waive the lab membership free for WCARC members! Additionally, the club plans to use the station as a base of operations, being more out in the public, in case of an emergency.

Issues the WCARC had to address are: legal agreements and unauthorized access to the station. Legal agreements are incredibly important. Their agreement spells out and covers both the lab and club should either entity disband, dissolve, or go out-of-business; for example, what happens to the Club’s equipment. A club seeking to do the same would need legal counsel or know one willing to do pro bono work to write up a legal agreement.

The BiG Fab Lab is a 24-hour facility. Having a station control operator at all times is unreasonable. The club, with the help of a partnering company, developed a method to allow the equipment to be turned on for anyone to listen. To inhibit transmitting, the microphone port will be disabled by default. Once a lab member becomes licensed or holds a valid amateur license, that achievement will be added to their access card just as if they were qualified on any other piece of equipment. When the member swipes the card with that achievement, the microphone port will be enabled allowing that licensee to transmit.

Having access to a full shop is an amazing resource and opportunity to get ham radio out in front of like-minded people. If a similar shop is not nearby, opportunities for clubs to participate in “Maker Faires” are available too. The article in QST describes them as “one part festival, one part flea market, one part rock concert.” Makers are brought together in a hamfest-like environment to display their projects including: 3D printing, electronics and microcontrollers, robotics and drones, music and dance, homemade electric vehicles, art and textiles, cooking, science, woodworking, and blacksmithing.

One theme that kept popping-up in the article: focus on making, not operating. Visitors are not interested in watching a ham making contacts or ‘get licensed’ pamphlets. Take an indirect approach to ham radio. Makers want to see Wi-Fi and Bluetooth used for wireless data links, long-range data systems (data modes, packet), microcomputers and inexpensive tablets, ADS-B, weather satellite receivers, spectrum analyzers, cable and antenna sweepers, and SDR – to name a few. Makers are already familiar with these technologies. Promote these topics – which lead to discussions on getting licensed. Explain ways ham radio can add value to their projects. A new wide area network technology called LoRa has makers really excited to be able to send bidirectional wireless data between 0.3 kpbs and 50 kbps over long ranges. Hams have been doing similar networking with packet and mesh.

Each year, do a different project to keep people coming back. Some examples of projects include demonstration on the relationship between wavelength, frequency, and changes in VSWR. Explain how communication efforts in a recent natural disaster could have benefited by building an NVIS antenna for a particular band. Have a display prepared on antenna resonance with some hands-on activities. An SDR, antenna, and computer could show different signals on a spectrum display. Bring lots of Raspberry Pis, Arduinos, and circuit boards. Be patient as it may take some time to get a maker licensed. Who knows, they may become your club’s most active member.

I challenge clubs to contact these organizations and form a partnership with a local makerspace or participate in a maker faire. I found a number of maker spaces throughout the section including the Columbus Idea Foundry, dubbed “the largest makerspace on the planet” by Tech Crunch. Doing some searching on the Internet leads to maker faires in different parts of the state. Not only is the Wood County Amateur Radio Club pioneering in the maker arena, the Alliance and Massillon Amateur Radio Clubs are involved with the University of Akron Wayne College 3 (UAWC3) Lab.

Efforts to get ham radio into schools for younger adults is great. I think the buy-in from administrators is far too high because it does not fit into their method of teaching to the standardized tests. I’ve been a part of conversations where the feeling that recruitment in scouting programs has not been as favorable as anticipated. Efforts could be better utilized by sharing our hobby with makers, who tend to be younger adults and college aged students with a similar mindset.

THE TECHNICAL COORDINATOR
Jeff Kopcak – TC
k8jtk@arrl.net

DSCF5081 K8JTKHey Gang,

On Sunday, February 12, I connected up with the Central Ohio Radio Club located in, you guessed it, central Ohio! They have a Tech Net most Sunday evenings at 7:30pm. They asked me to be the featured guest on one of their nets. Some of you might realize this causes a problem since I live in the Cleveland area. Enter the technical side of the hobby and IRLP. IRLP (Internet Radio Linking Project) is a service that connects amateur stations together using Voice over Internet Protocol (VoIP). Different from other ham radio VoIP services, IRLP requires the Internet link be connected to an RF link, usually a repeater or simplex node. Using the LEARA 146.880 repeater in Cleveland (a club which I’m Vice President and a bunch of other stuff) and Internet linking technology, I was able to join their net as if I were local to Columbus.

The CORC Tech Net contacted me looking for information on technical resources available in the section. I got the chance to do an introduction about myself – we’ll quickly move past that 😉 Then I talked about how the technical resources fit into the ARRL organizational structure. If you’re new or haven’t looked at it before, at the top are the ARRL Officers: president, first & second vice presidents, COO, etc. The ARRL Board Committees include the Executive Committee, Administration & Finance, Programs & Services, Public Relations, DX, LoTW, etc. Then Divisions, of which there are 15 total, with Director and Vice Director positions. In Ohio, we’re included in the Great Lakes Division. Finally, our section is the Ohio Section where Scott – N8SY is our fearless leader and Section Manager (SM).

Below the SM are their appointees who may or may not include (depending on the section): Section Traffic Manager (STM), Section Emergency Coordinator (SEC), Assistant Section Manager (ASM), Official Observer Coordinator (OOC), Technical Coordinator (TC), Affiliated Club Coordinator (ACC), Public Information Coordinator (PIC), State Government Liaison (SGL), Section Youth Coordinator (SYC). If you’re reading this, the people above and below me in this Journal make up this list. I won’t spend too much time here as details can be found on the “About ARRL” page at http://www.arrl.org/about-arrl.

As the Technical Coordinator, I’m responsible for the Technical Specialists. The Specialists and I are here to promote technical advances and experimentation in the hobby. We encourage amateurs in the section to share their technical achievements with others in QST, at club meetings, in club newsletters, hamfests, and conventions. We’re available to assist program committees in finding or providing suitable programs for local club meetings, ARRL hamfests, and conventions in the section. When called upon, serve as advisors in RFI issues and work with ARRL officials and appointees for technical advice.

The Technical Specialists really make all this happen. In the Ohio Section, there are about 20 qualified and competent Specialists willing to help. They meet the obligation of advancing the radio art bestowed to us by the FCC. The TSes support the Section in two main areas of responsibility: Radio Frequency Interference and technical information. RFI can include harmful interference (interference that seriously degrades, obstructs, or repeatedly interrupts a radiocommunication service) from bad insulators on telephone poles to grow lights and poorly made transformers, RFI direction finding, or assist in locating bozo stations. Technical information is everything else from building antennas, repeaters and controllers, digital, computers, networking, and embedded devices.

How can we help? The knowledge and abilities of your Technical Specialists are quite impressive. Here are some examples of the knowledge the Technical Specialists provide:

  • Documentation and training.
  • VHF/UHF portable operation.
  • Antennas (fixed, portable, and mobile).
  • Batteries and emergency power.
  • Experts in RFI from powerline and consumer devices.
  • VHF/UHF/SHF contesting.
  • Experts in test equipment.
  • Automotive electronic compatibility (EMC) and interference (EMI).
  • Repeaters.
  • Digital modes (D-STAR, DMR, Fusion, P25, APRS & IGates. HF: MT63, JT65, Olivia, PSK).
  • Computers and networking (VoIP – AllStar link, software engineering, embedded systems – Raspberry Pi, Arduino).
  • Society of Broadcast Engineers (SBE) members knowledgeable in interference problems.

This impressive list of qualifications is available to all in the Ohio Section. Looking for help in one of these areas? Feel free to contact myself. My contact info is near my picture and on the arrl-ohio.org website. I’ll try to assist or get some more information from you and put you in touch with an appropriate Technical Specialist. One of the Specialists might hear a plea for help and reach out to you as well. If you would like to add your talents, check out the description at the ARRL site: http://www.arrl.org/technical-specialist and talk to Scott or myself.

Thanks again to CORC (http://corc.us/) for inviting me as the featured guest on their Tech Net and LEARA (http://www.leara.org/) for the use of the IRLP node to make this connection possible.

That’s about it for this month. Stay tuned for next month’s article, got something good planned. Thanks for reading and 73… de Jeff – K8JTK
