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

THE TECHNICAL COORDINATOR
Jeff Kopcak – TC

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
