THE TECHNICAL COORDINATOR
Jeff Kopcak – TC

DSCF5081 K8JTKHey gang,

As Technical Coordinator for the Ohio Section, I oversee the section’s group of Technical Specialists. The Specialists and I are here to promote technical advances and the experimentation side of 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 within the section. When called upon, serve as advisors for RFI issues and work with ARRL officials and other appointees for technical advice.

Technical Specialists are a cadre of qualified and competent individuals here for the “advancement of the radio art,” a profound obligation incurred under the rules of the FCC. TS’s support myself and the section in two main areas of responsibility: Radio Frequency Interference (RFI) and Technical Information. They can specialize in certain areas or be generalists in those areas of responsibility. Those responsibilities include serving as consultants or advisors to local hams or speaking at local club meetings on popular topics.

In the Ohio Section, there are 14 qualified specialists able and willing to assist. EMI/RFI includes harmful interference that seriously degrades, obstructs, or repeatedly interrupts a radio communication service such as ham radio or public service agencies. RFI sources range from bad power insulators, industrial control systems, other transmitters or poorly made transmitters, personal devices like computers, monitors, printers, game consoles, to grow lights, failing transformers, and poorly made transformers – including one’s hams brag about getting from China for a few dollars. I die a little inside when I hear this. Our Technical Specialists can offer advice to help track down interference or locate bozo stations. Technical information is a wide-ranging category including everything from antennas to Zumspots.

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

  • Antennas (fixed, portable, and emergency operation type) and feedlines
  • Antenna systems such as towers, guying, coax, and baluns
  • RF and tower safety
  • Grounding
  • Propagation
  • Electronics and circuits
  • Tube technology, aka boat anchors
  • Voice and data modes – including D-STAR, DMR, Fusion, NXDN, P25, APRS, IGates, packet, MT63, FT8/4, Olivia, PSK, and using programs like Fldigi
  • NBEMS – Narrow Band Emergency Messaging System
  • Computers, Windows and Linux, Raspberry Pi
  • Embedded devices
  • Networking: IP networks, AMPRNet, routers, firewalls, security, mesh, and microwave
  • Repeaters, controllers, and high-profile systems
  • Internet and VoIP linking systems – Echolink, AllStar, HamVoIP, DVSwitch, and PBX/Asterisk
  • RFI detection from power lines and consumer devices including working with governmental agencies to track down interference
  • Professional certifications such as Motorola Certified Technicians, Certified Journeyman Electronics Technician, General Radiotelephone Operator License (GROL), and Society of Broadcast Engineers (SBE) affiliations

This impressive list of qualifications is an available resource to all in the Ohio Section. Looking for guidance in one or more of these areas? Need a program for your club meeting? How about a technical talk or forum at your hamfest? Assistance or direction on a project? Feel free to contact myself. My contact info is near my picture and on the arrl-ohio.org website. I’ll assist getting you in touch with an appropriate Technical Specialist. If you’re interested in being a Technical Specialist, take a look at the description on the ARRL site and get in contact with me. I’ll keep you in mind when a spot opens up.

One of the activities that got canceled over the last year-and-a-half was the West Chester Amateur Radio Association’s (WCARA) trip to K3LR’s contest station. The station is not far into Pennsylvania on I-80. You’ve likely seen it if you’re taking the turnpike into PA and look to the right about a mile after crossing the border. I decided to get out of the house and have my second tour of this marvelous station. For me, it’s only about an hour and a half drive. The rest of the club came fr

K3LR operating positions

om just north of Cincinnati, closer to 5+ hours each way with breaks and food. Tim is an excellent host as always and an amazing engineer. He built the station over 35 years and has one of the quietest noise floors you’ll ever see. As he’ll tell you, it didn’t come easy. He’s got really good stories including one involving a late-night party. I’ll leave that one for him to tell! It was great to get out of the house for a day and hang out at a superstation with the guys from VOA.

Above the clouds – antenna changeout view (YouTube)

Speaking of towers, if you’re like me and wonder what it’s like to work at a commercial tower site or TV tower, I came across a half hour video of tower work from the crew’s prospective. This video documents the entire changeout of the antenna from removing the old one to putting the new one in place. The tower crew and air-crane crew replace the television transmitting antenna for WTVX in West Palm Beach, Florida. You get to see what it is like to be working on a 1,500′ tower. It’s quite impressive with breathtaking views but one of the riskiest jobs in the world.

Field Day is completed by the time you read this. Keep this in mind for next year. Sending 10 messages over RF from your site gets you 100 bonus 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 – to my station. Field Day rules state messages must leave via [ham radio] RF from the site (7.3.6). It does not state “formal messages” be in any particular format or utilize any particular network. A message to the SM or SEC must be in radiogram format and leave via RF or no credit will be given (7.3.5). Copies of messages are included with the submitted Field Day report.

With July around the corner, if you’re looking to do something while flipping burgers at your 4th of July picnic, my favorite event is the 13 Colonies Special Event which will be on the air July 1st (9AM) – July 7th (midnight). There is an additional France bonus station this year, TM13COL. This is in addition to the bonus stations WM3PEN and GB13COL. A station does not need to work all 13 colonies to receive a certificate. The three bonus stations do not need to be contacted for a clean sweep.

DSCF5081 K8JTKHey gang,

KA6LMS Special Event – Going QRT with a bang! … most certainly lived up to the name. Last Man Standing is a television sitcom starring Tim Allen. Tim plays Mike Baxter, a married father of three daughters and grandfather to a grandson. His character is an executive for a chain of sporting goods stores called “Outdoor Man.” John Amodeo – AA6JA is the producer of the show. As John tells the story, when the character of Mike Baxter was being developed, an aspect to this character was the ability to live “off the grid” in addition to fishing, hunting, and camping. John, being a licensed ham radio operator, proposed the idea of using ham radio to fill part of the character profile, and it was ultimately included in parts of the show.

This led to the factitious callsign for Mike, KA0XTT. The XTT was a throwback to one Tim’s former shows “Home Improvement” being formally (or ex) Tim Taylor, XTT. A small number of episodes included ham radio plots. Though shots of radio gear, QSL cards, and ARRL books are seen in the background of Mike’s office in nearly every episode. Ham gear seen in his office was fully functional according to Amodeo. Also seen on occasion was a setup in his basement and it was the focus of one episode.

Featuring ham radio on the show lead to interest and resulted in a number of cast and crew members becoming licensed hams, including Tim Allen and Jet Jurgensmeyer – who was the second cast member to play Boyd on the show. I heard recently that Tim plans to use ham radio as backup communications in case of emergency between properties he owns. I can’t imagine Tim getting on the air and not causing a pile-up! With all those licensed operators, a club was formed by the cast and crew called the Last Man Standing ARC, KA6LMS.

The show was originally carried on ABC stating October of 2011. Then unceremoniously canceled after six seasons despite being one of the highest rated shows on the network. ABC said it didn’t want to pick up the production costs but many believe it was canceled because – well, Mike Baxter was right leaning politically, the media’s least favorite candidate just became president. You put 2 and 2 together. The show returned in 2018 on Fox, where it ran for three more seasons and is scheduled to end its nine-season run on May 20, 2021. Unfortunately, in the transition, many cast members signed onto other projects and a good number of cast members were replaced or given recurring roles.

There were many criticisms by hams about the show including the lack of ham radio themed episodes. Episodes that featured ham radio came with complaints: ‘they were illegally transmitting and not identifying correctly.’ I love it that hams think ham radio appeals to everyone and that the world revolves around ham radio. When you talk TV shows it’s all about ratings – how many people are watching your show? To have a couple million viewers per episode is not going to cut it. There are not even a million licensed hams in the United States. The producers need to appeal to wider audiences of about 7 million viewers, otherwise there wouldn’t be any show at all. I’m thankful for the publicity we did receive. Want to make a prime-time TV show on a major network about ham radio? Do it. Let me know how that works out for you.

Over the years, AA6JA made many appearances on podcasts promoting the show, letting the ham radio community know the show loves ham radio and the ham community let him know we loved the show. For the many years of support, John wanted to do something special for hams as the show is winding down its final season. His idea became one of the biggest special events that many have ever seen and certainly the biggest where I had been involved.

The Last Man Standing Special Event started March 24, 2021 and ran through March 30th. This coincided with the taping of the final episode which also concluded on the 30th. All call districts were represented, KA6LMS/0 through KA6LMS/9. There was KA6LMS/On-Stage, KA6LMS/VE3, KA6LMS/VE7, and bonus stations of K6L, K6M, K6S, W6L, W6M, W6S (suffixes spelling out L-M-S) were all run by celebrity ham radio operators, contesters, and podcasters. This event covered HF, HF digital, VHF/UHF, VoIP digital, moonbounce, packet, and satellite. It was an all mode, all band special event. Final stats from the KA6LMS special event site:

LMS is in space! Over 134 Moon Bounce (with pile ups) and over 100 Satellite contacts including 7 packet QSOs through the ISS!

LMS had over 88,056 QSOs! 50 States, 139 Countries, 1,864 Counties, 1,187 Grids, 9,840 Grids(6)

The AmateurLogic.TV podcast has been using my Digital VoIP Multimode Interlink System (DVMIS) for their Tuesday evening net. They asked early in the planning if they could use my system for a multimode QSO party as part of the Last Man Standing special event. Of course! At first, I didn’t think much of it because I had been a part of D-STAR/DMR/Echolink special event stations in the past. For the number of contacts made, I would have only considered those events to be moderately successful. No one anticipated what happened the night of March 27th.

AllStar Link connection graph during the event. Blue is my system, white are public nodes, pink are private nodes.

As the start of the QSO Party drew closer, more, and more, and more, and more stations were connecting to reflectors that are part of my system. I was able to count 300 stations connected into my system and wouldn’t be too farfetched to believe it was more like 500 total stations were connected! Taking into account where I could not determine number of connected stations (Brandmeister, TGIF) and other Echolink Conferences that linked into mine. Internet traffic send and received was close to 20 GB.

The event was WAY more popular than anticipated. The ALTV guys thought the QSO party would run 3-4 hours. It ran for just under 8.5 hours! and still had stations wanting to check in. The whole event was streamed live on YouTube. I don’t know how long the video will remain up but as of this writing it was still available.

We learned some things:

1) Stations really need to listen and follow instruction. If you’ve worked any contest, DX, or special event, this is nothing new. When the net controller says ‘we’re going to pass it over to the net controller to begin,’ that is not the time for everyone to start throwing out their callsign where the net controller couldn’t break in for nearly 5 minutes.

2) Stations, mostly Echolink, need to eliminate courtesy tones, squelch tails, hang times, and the like from going out over the network. That caused problems where stations just ping-ponged back and forth. One transmitted their courtesy tone, then another with its hang time, etc. to over 500 Internet connected links. Set the repeater to use TX PL only when a signal is active on the repeater input and link radio to use RX PL COS to transmit audio.

3) AllStar gave me fits. The program segfaulted on me a couple times early on. For those not in computers/programming segfaults are very bad and often result in crashing the program or system. Haven’t gotten any advice how to troubleshot, but I have a couple things to try.

4) Wires-X stations got frustrated because they thought the link “wasn’t working” or had “one-way audio.” Being the proprietary closed-source implementation that Wires-X is, not being able to link that system using free and open source packages results in additional buffering that happens on the network, to the tune of 3 seconds. When a Wires-X transmission originates from that network, it is 3 seconds before the transmission is heard on the rest of the system. IF someone, within that 3 seconds, keys on any other mode – the Wires-X transmission is completely bumped from the system. Do I need to refer back to the ping-ponging mentioned above? In addition to being a popular event, it was almost guaranteed someone else keyed up before a Wires-X station could break in. If my system is used for a QSO party that large in the future, I would recommend not using Wires-X as a result and having those stations find alternative means.

Aside from those issues, my system handled the load without breaking much of a sweat. Wow, what an accomplishment! That’s going to be one I remember and talk about for a long time. It was a long day for me too as I had an early upgrade at work and by the time I went to bed, had been up for 24 hours. Closer to the end of the LMS event, the Amateur Television Network (ATN) linked into my system and transmitted around the world via ATN and on YouTube, all while working stations.

Thanks to the Amateur Logic.TV guys for their QSO party. Thanks to John Amodeo – AA6JA, everyone that put this event together and used their stations to make this event possible. Of course, thanks to everyone that participated making this event 88 thousand contacts successful! Certificates are now available for download on the special event website: http://gsbarc.org/lms/. John hopes to keep the Last Man Standing ARC and KA6LMS call on the air by doing other special events in the future.

Last but certainly not least this month, I would like to thank the Portage County Amateur Radio Service (PCARS) for having me at their meeting March 8th. They asked me to give a presentation on ham radio voice over IP (VoIP) and my interlink system. It was great to get out and travel to a meeting in person, though those who wanted could attend virtually. If you would like to have a VoIP presentation and demonstration of my interlink system, contact me at my email found at the beginning of this article. Already there have been new things added since the presentation.

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

DSCF5081 K8JTKHey gang,

Not quite one year after the OpenSPOT 2 was released, the OpenSPOT 3 made an appearance on the SharkRF website. I suspected the OS2 was not selling very well. A quick look at the Brandmeister Dashboard shows 7.4% are using the OS1 and 2.5% are using the OS2. These are number of hotspots connected to the Brandmeister network on the evening of March 24th and does not include other networks.

Maybe low usage is a result of the six-month lag since stopping production of the blue box OpenSPOT 1 and when the OpenSPOT 2 arrived on the market. Maybe it was making the announcement to discontinue the OS1 right after Dayton (two years ago) upsetting customers who just spent money at the show on a now obsolete device. By obsolete, I mean can’t purchase the device new (no longer in production) and there’s been maybe a single firmware update since it was discontinued. I get it, they’re a small company out of Estonia but their business and design decisions upset customers.

Not to mention vendors. The blue box could be obtained from many ham retailers. They too probably felt burned after the OpenSPOT 1 to the point where I don’t see any retailers carrying the 2 or 3. Purchasing from a retailer meant users could forego the international transaction fees and shipping, or they were just included in the price.

OpenSPOT 1

I love the OpenSPOT 1 and think it’s a solid device. It beat all other offerings at the time and one of the first devices to offer cross mode support (DMR <-> YSF). At the time, Pi-STAR wasn’t a thing. The DV4Mini was one of the first multimode offerings but it stank-on-ice (it became usable recently with an MMDVM application). The DVMega and other devices around the same time were solid hardware but getting a working image (software) was a challenge. The problem with the OpenSPOT 1, it was wired Ethernet, didn’t offer a Wi-Fi option, and required USB power. A wireless bridge such as the TP-Link N300 made it Wi-Fi capable, via a wireless bridge, allowing the device to be paired with a cell phone hot spot or other Wi-Fi link. I was able to make a similar setup work on my Linux laptop acting as a NAT (network access translation – same as home Internet connections). Had a script to setup the DHCP server on wired Ethernet (where the OpenSPOT 1 would be connected) and iptables rules allowing communication from the wired Ethernet to the wireless interface (where the cell phone or hotel Wi-Fi would be connected). USB power could be a portable USB battery pack or plugged into the laptop USB. These setups worked but most found it not great for portability and keeping track of multiple devices.

I skipped the OpenSPOT 2. Shortly after release came reports of both Wi-Fi and radio range issues. To improve on design, SharkRF internalized the 440 MHz antenna as well as adding Wi-Fi capability, also removed the wired Ethernet. Apparently, the device had to be very close to Wi-Fi access points and the digital radio couldn’t be very far away either. It would work great in small areas like a car but it wasn’t winning bonus points for range. Coming out with another successor in less than a year was likely an acknowledgment of these problems.

OpenSPOT 3 (sharkrf.com)

Picked up the OpenSPOT 3 on a Christmas special from SharkRF and had a few months to use it. The OpenSPOT 3 is probably the most advanced digital hotspot available for ham radio, and also the most expensive. Cost came to €243 EUR including shipping, $288 US. For what it is, it’s a great device. Comparing it to a device with an external antenna, you’ll be disappointed.

It comes with a built-in Lithium-ion battery, built in radio and Wi-Fi antenna, USB-C for fast charging (though battery life seemed short under heavy usage), it has the same solid web interface as the OS1 with some nicely added tweaks including the ability to play audio from the web interface. Overall, it is fast. The web interface doesn’t lag and time to connect from power off is under 10 seconds. In comparison, my Pi-STAR on a Raspberry Pi Zero-W takes a couple minutes to boot and nearly 50 seconds to save and change any settings. Setup was easy with any web browser, including mobile. It offers the ability to work all current digital modes: DMR, D-STAR, NXDN, P25, and YSF. Also offers POCSAG and APRS-IS forwarding.

For the ham-on-the-go, this is the best option for a digital hotspot. The OS3 features a built-in hardware AMBE chip for transcoding, including D-STAR to other network types. This is the first and only hotspot with D-STAR cross-mode functionality built in and was the most requested feature that I saw on the forums. That means a D-STAR radio can work on DMR, C4FM (YSF), and NXDN networks. Likewise, a DMR radio can access D-STAR, C4FM, and NXDN networks. This is the perfect option for a traveling ham that wants access to digital while on the road but doesn’t want to bring all the radios. Table below notes which radios will be able to work which networks.

Radio/transceiver Networks
Hardware cross mode support
DMR D-STAR, C4FM, NXDN
D-STAR DMR, C4FM, NXDN
C4FM DMR, D-STAR, NXDN
NXDN DMR, C4FM, D-STAR
Software cross mode support
C4FM P25
P25 C4FM

I don’t know how bad the antenna issues were on the OS2 but I can’t imagine them being much worse than with the 3. I have always run hotspots on the lowest power setting because the lowest gave more range than I ever needed, however they all used external antennas. Depending on interference from nearby computers, I had some trouble with the device falling out of radio and Wi-Fi range. On average it would cover the footprint of the house. I bumped the power up to 20% and still have reliability issues of it hearing me or me to hearing it from out in the shack – with an external antenna. I’m a little disappointed by that. Another issue, P25 sounds better on the Pi-STAR for some reason – even after doing a calibration on the OpenSPOT.

Someone wanting a feature packed device for traveling, this is currently the best option. If you want range, stick with a hotspot that has an external antenna.

KA6LMS QSL card

By the time the Section Journal goes to press, most of the event will be completed – but there’s still time! The Last Man Standing special event is well underway. It commemorates the last week of taping for the TV show Last Man Standing which is ending its 9-season run. The special event will cease operation 3/30/21 at 23:59 UTC, so you still have some time. This event is everywhere: SSB, CW, FT8, D-STAR, DMR, YSF, NXDN, P25, Hamshack Hotline, Echolink, Satellite, EME, AllStar, ATV and probably a few more I’ve forgotten. Everyone including Technicians can get on board. There are promo videos and an information site with details about call signs, log sheets, how to send QSL cards, and the certificate. Look for KA6LMS/1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 as well as K6L, K6M, K6S, W6L, W6M, and W6S bonus stations. My multi-link system will be part of the event that happened on the 27th. I should have stats and info on how that activation played out next month. After the 30th, Last Man Standing will be QRT.

Lastly, something I didn’t know existed. RFC 1149 defines an experimental standard to encapsulate IP traffic using avian carriers (IPoAC). That’s right, IP packets via carrier pidgins! It is really useful in Metropolitan Area Networks (MANs). Devices in your home are connected to a Local Area Network (LAN). These LANs would be connected to larger regional networks called MANs. “Avian carriers can provide high delay, low throughput, and low altitude service.” They also have collision avoidance systems increasing reliability. Unlike packet radio, these communications are not limited to line-of-sight. Format is very easy to understand and follow:

The IP datagram is printed, on a small scroll of paper, in hexadecimal, with each octet separated by whitestuff and blackstuff. The scroll of paper is wrapped around one leg of the avian carrier. A band of duct tape is used to secure the datagram’s edges. The bandwidth is limited to the leg length. The MTU is variable, and paradoxically, generally increases with increased carrier age. A typical MTU is 256 milligrams. Some datagram padding may be needed.

Upon receipt, the duct tape is removed and the paper copy of the datagram is optically scanned into a electronically transmittable form.

Wonder if I have to install a landing pad or birdhouse to have these messages delivered?

 

April fools! Emile – KE5QKR was talking about this after taping one of the Amateur Logic shows and I had to look it up. It really does exist but once I saw the April 1, 1990 date – I knew it was an April Fools’ prank. There’s your early April Fools’ joke for later this week!That’s about it for this month.Thanks for reading and 73… de Jeff – K8JTK

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,

Where to start?  Lot has gone on the last month.  First up was the Cleveland Hamfest on the 27th.  The weather was great for a change – which, I thought, brought more people.  Seemed to be more flea market and vendor spaces taken up which is always good.  I heard from HAC that it was a successful hamfest this year.  I got to say howdy to a few in the Ohio Section cabinet.  I know I’ll forget someone but thanks to everyone that said hi and congratulated me.  Helped out with some of the local clubs, organizations, and shot the breeze with them.  Spent a couple of bucks too, mostly on connectors and accessories I was looking for.  You can always use more connectors.  Had just as much fun at the after party.

You didn’t know there is an after party?  Oh, there is… just some of my closest buddies getting together afterwards for some lunch.

The following day, I gave my Raspberry Pi presentation for the Geauga Amateur Radio Club and had a blast!  If you’re on the east side of Cleveland, be sure to check them out.  Made for a long day with work but was totally worth it!  There are two versions of this presentation available for viewing on my website at http://K8JTK.org.

The Northern Ohio Amateur Radio Society (NOARS, Lorain Co.) has asked me to put on the Pi presentation for their group too.  I’m scheduled to be the presenter at the November 16 meeting.  If you haven’t seen this thing yet, don’t miss it!  More info: noars.net.

Welcome to Dave KD8TWG as the newest Technical Specialist!  I’ve known Dave since about the time he became licensed because he’s been very active.  In addition to being AEC for Geauga County, he is into embedded systems, computers, and networking.  He plays around with APRS a lot too.

Aside from all that goodness, QSL cards and certificates are coming in from the 13 Colonies and Katrina 10th Anniversary special event stations.  I just dropped off certificate requests and QSL cards for the Route 66 and Pope Francis special event stations.  Groups really put in a lot of work doing these special event stations and do a great job getting the certificates and reply QSL cards out quickly.  The certificates really make great wallpaper for your shack too!  I find special event stations by watching Ham Nation or spots on DX clusters.

The Hurricane Watch Net is celebrating 50 years of service.  It was started in Cleveland by Jerry Murphy – K8YUW as an informal net to provide communication to affected areas.  They activate on the HF bands anytime a hurricane is expected to make landfall.  They can be heard on 14.325 MHz and 7.268 MHz.  Remember to stay clear of these frequencies while the net is activated.  More info: http://hwn.org.

LEARA is in line for a Yaesu Fusion repeater under their promotional deal.  We are eagerly awaiting the arrival of the box and can’t wait to get it on the air.  The promotional deal is a great opportunity for your club to replace aging repeater equipment or experiment with digital modes.  I can’t tell you how excited members of the club are to get into System Fusion.  From the other clubs that have contacted me regarding Fusion, the excitement is contagious.  Give it a shot!  The repeater can be configured: full digital (digital in – digital out only), full analog (analog in – analog out only), or auto detect (eg: analog or digital in – analog out, digital in – digital out, analog in – analog out).

Yaesu has extended the promotion once again until the end of the year, so you or your club has some time to decide.  Details and application are available through yeasu.com -> select Products -> click Digital.  Click DR-1X (model of the repeater).  Click the Files tab -> click “DR-1X Installation Program Application form.”

Thanks for reading
