Dayton Hamvention 2026: Day 3, Friday, May 15 – Forums

May 24, 2026 By Dan KB6NU Leave a Comment

The forums at this year’s Hamvention were pretty good—and I’m not just saying this because I was on the schedule. I spent most of Friday morning cruising the vendor booths and schmoozing with people I know. I stopped by the CWops booth, the Amateur Radio Digital Communication (ARDC) booth, and the Youth on the Air (YOTA) booth. In the afternoon, though, I spent most of my time attending the forums.

The first talk I attended was the Long Island CW Club (LICW) presentation, “Our CW Journeys.” I was interested in this talk because I’m in the process of updating my CW book and wanted to learn more about their process.

The presentation consisted of several “testimonials” from members how they learned Morse code by taking LICW classes and participating in LICW activities. The stories were very intriguing, and kudos to LICW for helping people have fun with Morse code.

Next, I stopped by the “Amateur Radio and the Law” forum to say a quick hello to Fred, K1VR, and Bob, K3RF. I didn’t stop to hear the talk, though, as my next stop was the “Hackers in Ham Radio” forum.

This forum was a panel discussion, led by Jeremy, KD8TUO. The discussion was a bit unorganized, but they did talk about how the hacker and ham radio communities intersect. I think that these two communities should intersect even more, and as part of Ham Radio Village, I’m helping to do that. Hackers are the kind of people that we want in ham radio.

The final forum of the day for me was “The Latest from ARDC: Grants and 44Net.” At this forum, folks from ARDC talked a great deal about their latest development, 44Net Connect. It’s taken ARDC a while to get to this point, but it looks to me like they’ve made connecting to 44Net a lot easier than it has been in the past, and I’m looking forward to see what use hams make of it.

There were also short presentations by a couple of their grantees, including the Digital Library of Amateur Radio and Communications (DLARC) and AMSAT. It’s always great to hear what other grantees are doing. ARDC has made a real difference in amateur radio, and I’m happy to say that it looks like they will continue to do so.

Dayton Hamvention 2026: Day 3, Friday, May 15

I feel a little guilty. I haven’t paid for a Hamvention ticket in several years. When I worked for ARDC, I had a vendor pass. That was nice because I could park in the vendor parking lot directly behind the fairground buildings. Last year, I finagled a media badge as a member of the ICQ Podcast. This year, I was issued a speaker’s badge (more about my talk in an upcoming post).

Not having to pay for a badge is not what makes me feel guilty, though. Aside from perhaps the media badge, I certainly gave back to Hamvention in some way. They got their money’s worth.

What does make me feel a little guilty is not having to wait in line until 9 am to get in. When you have a speaker badge or vendor badge, you can just walk right in.

This year, I arrived at the Greene County Expo Center a little before 8:00 am, parked my car, walked right up to the speaker/vendor window and picked up my badge, then walked right into the fairgrounds. How cool is that?

This worked out really well. A friend of mine wanted me to visit the HRO booth and purchase a radio for him, and since I got in early, I was able to beat the crowds. The guys behind the counter were a little miffed at first as they weren’t quite ready for customers, but they accommodated me, and I was very thankful to them for that.

Next, I stopped by the Linux in the Ham Shack booth. This has become a tradition with me, and I always enjoy saying hello to Cheryl, W5MOO; Bill, NE4RD; and in the past, Russ, K5TUX. Unfortunately, Russ is no longer with us, but it was still nice to check in with Bill and Cheryl.

After visiting with the LHS crew, I tromped around the flea market for a bit. I wasn’t looking for anything in particular, but I always like to see what people are selling.

I was kind of interested in a device that one guy was selling – a Gonset Model 3022 3-Way Code Oscillator. I’d never seen one of these before. It’s really a multi-purpose station accessory. It can be used as a code practice oscillator, but also as a CW sidetone generator or an AM phone monitor. The guy was asking $30 for it, though, and it was still pretty early, so despite his heavy sales pitch, I passed on it. I told him that I might be by later to see if he still had it.

I found another guy who was selling ham radio coffee mugs. There were a couple of those that I found amusing, including one that read “FT8” inside the international no symbol. He also had one that read, “Education is important, but ham radio is importanter.” Since I knew that my wife would kill me if I brought home another coffee mug, I passed on those, too.

Other than that, I didn’t really find anything that I wanted to buy in the flea market. Perhaps one reason is that there seemed to be fewer flea market vendors this year. There were big gaps between vendors in some of the aisles. I’m thinking that with such high gas prices this year, many sellers decided to skip Hamvention altogether.

More about Day 3 in my next blog post.

Dayton Hamvention 2026: Day 2, Thursday, May 14

May 20, 2026 By Dan KB6NU Leave a Comment

Four Days in May is an activity of QRP-ARCI.

Day 2 started out pretty early. The Four Days in May (FDIM) seminar starts at 8 am!

After a short drive from my hotel, I arrived at the DoubleTree Hotel a little after 7:30 am, expecting to sail in and claim a seat. I was, however, was surprised to see a line snaking down one of the hallways. Apparently, they weren’t letting people in yet.

As I walked down the hallway to take my place at the end of the line, I came across my friend Tom, W8TJB, who graciously let me take cuts. As it turned out, there were plenty of seats, though, so that was not a big deal. Here’s a short description of the talks I heard:

A Homebrewer’s Journey: How I got to where I am. Harold Smith, KE6TI, gave the first presentation of the day. He detailed his journey, from his high school days in the early 1960s to today. Harold’s talk included a lot of useful tips, but my big takeaway was, “When you’re homebrewing, you’re building for yourself.” With that in mind, Harold advised to not worry so much about how a project looks, or even how well it works. Focus on the enjoyment you had building something and what you learned from working on it.
Life is NOT Too Short for QRP if You Know a Few Tricks. Anthony Luscre, K8ZT, was responsible for this talk. He provided many, many tips for successfully operating QRP including how to select equipment, what antenna to use, what bands top operate, what modes to operate, and what times to operate. He also gave quite a few tips on operating technique. One tip that I plan to follow up on is his tip to use the 4X4XM Propagation Tools to better understand propagation.
The CFT1: the design philosophy and lessons in good user interface. Jonathan Kayne, KM4CFT, a young ham who recently graduated from Virginia Tech, told us the story of how he came to design the CFT1, a five-band, QRP transceiver. In this very interesting talk, he detailed his reason for designing the radio (a very noisy QTH which drove him to operate portable) and the entire design process. I enjoyed this talk so much that I thought that I might even buy one of his radios, but the kit cost $320, and since I still haven’t finished building my QMX, I decided not to.
Post-Hurricane Helene: The Role of Practical Preparedness and Community in Emergency Communications. Well-known QRPer, Thomas Witherspoon, K4SWL, lives in the mountains in western North Carolina, right in the path of Hurricane Helene. He spoke about how the hurricane affected him and his family, but perhaps more importantly, how the people of his community bonded to get through the crisis. As he was talking to an audence made up of hams, he talked quite a bit about the importance of communications in keeping that community together. “In a disaster,” he said, “communications is not just about passing information. It’s about holding a community together when everything else falls apart.”
Learn CW Like a Boss. In this talk, Jerry Weisskohl, AC4BT, gave us some tips on how to improve our ability to send and receive Morse code. He strongly recommended the use of Morse Runner and detailed how he used the program to get better at receiving.
Vibe (AI) Coding for Radio Amateurs. AI is all the rage these days, and Dr. Stewart Bryant, G3YSX, showed us how we might use it for developing software for amateur radio projects. After introducing some of the concepts behind the current AI chatbots, he gave some examples of its use, including coding a VFO using an AD9851 and developing a GNU Radio script to display the spectrum of an audio input. Bryant is very big on the technology and urged us all to try it. I may just do that.

I say this every year, but FDIM really inspires me to be more of a builder/homebrewer/hacker. Maybe if I get more serious about it, I could even give a talk next year.

Let’s hit the park!

After sitting through these six talks, I was getting a little antsy, and seeing that the last two talks didn’t really interest me all that much, I decided to escape and activate a park. The park that looked the most promising was the Dayton Aviation Heritage National Historical Park (US-0732). At first I was a bit confused about the actual location of the park. The park actually consists of a couple of different locations, including the Wright-Dunbar Interpretive Center and the Huffman Prairie Flying Field. The POTA map shows the location of the Huffman Prairie Flying Field, which is out near Fairborn. Fortunately, I chose to go to the Wright-Dunbar Interpretive Center, which is in the Germantown section of Dayton. There is a nice, little park there next to the museum, which is perfect for POTA.

As I pulled into the small parking lot, I noticed a ham (whose call I don’t remember, unfortunately) there already. I got out of the car and walked over. He was trying to make some contacts with an Elecraft KH1 and and AX-1 antenna. He said that he wasn’t having much success but encouraged me to set up and give it a try, so I went back to my car and got my stuff. We chatted a bit more while I was setting up, and he seemed interested in my doublet antenna. After I got on the air and made a couple of contacts, he left.

Not long after, a group of four hams—N3AIR, N3VQH, K3MET, and KC3RMC—exited the museum and walked over. They had driven in from Pennsylvania and were taking in the sights. They were a fun bunch. We did the HT thing, and I got a park-to-park QSO with all of them on both 2 meters and 70 cm. Then, one of them took the picture above. I wish I’d gotten a selfie with them all.

We were joined by another ham—a W6—and they chatted while I operated. Like the first fellow, I didn’t have a whole lot of luck on 20 meters, but when I switched to 40 meters, I started making quite a few contacts. That’s one advantage of having a full-size antenna like my doublet.

After the Pennsylvania contingent took off, I operated a while longer by myself. All in all, I managed to make 45 contacts in about an hour and a half. Not a bad afternoon’s work.

Meeting the CWops

Two older men and a woman smiling at the camera. — At the CWops Dinner, I met, Howard, W1HRB, and his wife, Barbara.

My next stop was the CWops dinner. I met a lot of great operators there, many of whom I’ve worked on the air and/or swapped email with. Just before dinner was served, I found a seat between Steve, KJ5T, and Howard, W1HRB. Howard, and his wife, Barbara are shown in the photo above.

Howard, as it turns out, lives not very far from me, and I tried to recruit him to operate at one of our Field Day stations. He was unsure of his availability for Field Day, but said that he’d try to come to one of our club meetings. I think he’d make a great ARROW member, so I really do hope he comes to a meeting.

The dinner broke up about 9:30, and I head back to the hotel to get some rest for Hamvention the following day.

Dayton Hamvention 2026: Day 1, Wednesday, May 13

May 18, 2026 By Dan KB6NU 2 Comments

Last Wednesday, I began my annual trek to the Dayton Hamvention. I live pretty close (three and a half hours driving), but I like to attend QRP-ARCI‘s Four Days in May on Thursday, so I head down early. I used to actually leave verrrry early on Thursday morning to get there by 8 am (and not have to pay for a night in a hotel), but I gave that up several years ago.

A couple of years ago, I started doing Parks on the Air (POTA), so I take the opportunity to stop at a couple of parks on the way. My first stop is Van Buren State Park, which is just north of Findlay. It’s right off the freeway (I-75) and very accessible. I arrived about 11:30 am.

I set up in the picnic shelter (shown above) that’s near the entrance to the park. This was my third activation, and there’s never been anyone else using the shelter when I’ve operated from there. I set up my 66-ft. doublet at the far end of the shelter, by the trees.

That was my first mistake. I was in a bit of a hurry, since I wanted to get set up quickly, so that I could eat lunch while i was operating. In my haste, however, I didn’t anchor the mast very well, and it was very windy that morning. So, of course, the antenna blew over. Not only that, one leg of the antenna got caught in one of the trees that you can see in the picture. This particular tree sported some big thorns, which made disentangling the wire a bit of a challenge.

I did manage to get the antenna back in the air—and eat my lunch—but it was very chilly with the wind and all. I squeezed out 12 contacts in about 45 minutes, then decided to tear down and hit the road.

In 2024 and 2025, my next stop was Grand Lake St. Mary’s State Park near Celina, Ohio. It’s a lovely park, which oddly enough, has a small lighthouse on it. It’s more than 20 miles east of I-75, though, so I thought I’d try a different park this year for my second activation. That honor fell to Kiser Lake State Park.

Beautiful view of a lake. — It was kind of cloudy at Kiser Lake State Park when I got there.

Getting there was a bit of an adventure. Like many people, I use Google Maps for navigation. After leaving Van Buren State Park, I got back on I-75 for about 20 miles, at which point Google decided to direct me to the back roads. The closer I got to Kiser Lake State Park, the narrower the roads became. At one point, the road was so narrow that there wasn’t even a center line. The directions were true, though, and I arrived in good time.

It was still windy and chilly, though. I set up in a picnic shelter near the park entrance, making sure this time to securely anchor the mast. I was able to make 14 contacts in about 45 minutes, and then decided to call it quits.

The nice thing about operating from Kiser Lake State Park is that the route from there to Fairborn, where I was staying is short and takes the back roads, avoiding I-75. I got to the hotel in about 45 minutes. I headed over to the FDIM hotel, picked up my badge and then headed out to dinner. Overall, this was a great start to my Dayton 2026 adventure.

Zero Retries Digital Conference to be held on Saturday, September 13, 2025 in Everett, WA

August 15, 2025 By Dan KB6NU Leave a Comment

I should have posted this sooner. My bad. If you’re in the Northwest and are interested in digital communications, please consider attending this conference in person. If you’re not, you can still sign up to attend the sessions virtually. There’s even an option for your club to attend virtually….Dan

We are pleased to invite you to the Zero Retries Digital Conference (ZRDC) that will be on Saturday, September 13, 2025 at the Edward Hansen Conference Center in Everett, WA. Due to the pandemic and other reasons, there has not been an in-person Amateur Radio digital conference for several years or any known plans for upcoming conferences. With GNU Radio hosting their conference at the same venue the week prior to ZRDC, Zero Retries seized the opportunity to bring back the in-person Amateur Radio Digital Conference to the Pacific Northwest. However, if people are unable to travel, there are alternative means to participate on the conference page link below and on the registration form.

About Zero Retries

Zero Retries is a unique independent newsletter that promotes technological innovations in Amateur Radio. The Editor, Steve Stroh N8GNJ, writes the majority of the newsletter with an occasional submission by one of his readers. Steve refers to Amateur Radio as, literally, a license to experiment with and learn about radio technology. He often jokes, but is serious, that radios are now computers… with antennas.

About the ZRDC

Planned presentations and demonstrations will be designed to enhance the skills and knowledge of the participants with topics such as but not limited to the IP400 Networking Project, M17 Digital Voice/Data system, MMDVM-TNC data system, ARDC’s 44Net VPN, software defined radio (SDR) and AREDN, HamWAN and other Amateur Radio microwave networking. Attendees will have the opportunity to connect with peers, and discover innovative technologies that are shaping the future of Amateur Radio. A call for papers has been sent, which will provide the opportunity to learn from leading experts. The ZRDC 2025 will highlight the resilience and adaptability of the Amateur Radio community in the Pacific Northwest by embracing new platforms and technology that continue to foster the passion for radio communication.

In closing, I have created various ticket prices and multiple ways to participate. Please share this information as you see fit with others that might be interested. I have included the links below for registration and the conference. If you have any questions, please don’t hesitate to contact me. Thank you for your time and consideration and hope to see you at the conference.

Sincerely,

Operating Notes: 40-meter DX, two Ohio POTA activations

May 23, 2025 By Dan KB6NU 1 Comment

Recently, there have been some complaints about propagation on the HF bands. Last night, however, propagation was pretty good on the 40-meter band. I managed to work four DX stations, including one LU (Argentina), one YT (Serbia), and two HAs. All of them were S6-S7 and very good copy.

The two stations from Hungary were both from the same town (Miskolc). I’m wondering if the first one called up the second and let him know that propagation was good to the U.S.

Finally got Ohio in the POTA log

Last year, on my way down to the Dayton Hamvention, I activated two parks: Van Buren State Park and Grand Lake St. Marys State Park. Unfortunately, those logs never got uploaded. As I was leaving the second park, my phone died. And, it wasn’t just that the battery needed recharging. It was completely dead. I lost both logs, and when I got to Dayton, I had to buy a new phone.

This time, I had much better luck. Van Buren State Park is right off the I-75 freeway. As soon as you get off the freeway, you’re in the town of Van Buren. Drive through town (about four or five blocks) and you come to the park. I set up in a shelter close to the entrance because there was a possibility of rain. Despite complaints about poor band conditions, I made 30 contacts in an hour, including a couple of DX contacts. I would have stayed longer, but that evening, I was meeting some people for dinner, so I packed up and headed to the second park.

Lighthouse next to a lake. — Even though it’s an inland lake, Grand Lake St. Mary’s is so big that has a lighthouse.

The second park I activated was Grand Lake St. Mary’s State Park. I like this park because, even though it’s an inland lake, it has a lighthouse (see above). So, I get both a park activation and a lighthouse activation.

Grand Lake St. Marys is a man-made lake that was constructed in the early 19th century as a reservoir for the Miami and Erie Canal, which connected the Ohio River with Lake Erie. At one time the lake was the world’s largest man-made lake.

The threat of rain was even more real here, so I found another shelter to set up in. That kept me nice and dry. Unfortunately, the shelter I decided on was very close to some homes near the lake. The problem with that was that it was very noisy there. I managed to make 15 contacts in about an hour, but I know I missed at least one because he was down in the noise. I would have been able to make that contact if I’d been at Van Buren State Park.

After I packed up, it was off to Dayton. This time, my phone didn’t flake out on me, and I made it to the hotel in plenty of time to get ready for dinner. Overall, it was a great way to kick off my Dayton 2025 trip.

Why aren’t electronic badges more of a thing in #hamradio?

August 19, 2024 By Dan KB6NU 6 Comments

Electronic circuit board with LED screen and buttons. — DEF CON 32 electronic badge.

I attended DEF CON 32 a week or so ago, and like many “hacker” conferences, attendees got an electronic badge. This year’s badge was built around the new Raspberry PI microcontroller, the RP2350. It actually works like a GameBoy, and you can add games like you would a GameBoy. Here are a couple of videos that talk about the DEF CON 32 electronic badge:

Some of the “villages” or special interest groups, such as the Aerospace Village created their own badges.

At DEF CON, I attended a talk by a fellow who’s created an open-source design—both hardware and software—upon which you can build a badge for your event. He calls his badge OpenTaxus, and you can find the documentation here.

Since these things are so popular at hacker conferences, I wonder why they aren’t more popular at amateur radio events? Is it because hams are just too cheap to buy something like this? Or, maybe, it’s because hams are just not as “creative” as hackers.

At any rate, I’m thinking about coming up with some kind of electronic badge for the 2025 Dayton Hamvention. If any of you have ideas for the badge—or would perhaps be interested in working on the badge hardware or software—let me know. If we are going to do a badge, it would probably be a good idea to get started on it now.

Hamfests are as much about meeting people as they are about selling stuff

March 18, 2024 By Dan KB6NU Leave a Comment

From L to R, KB6NU, KW1L, and K8BMA at the 2024 TMRA Hamfest.

Yesterday, my friends Paul KW1L, Rick K8BMA, and I drove down to Toledo for the Toledo Mobile Radio Association (TMRA) hamfest. This is generally a well-attended event, so I schlepped a bunch of stuff down there. Some of it was my junk, some of it odds and ends from the estates I agreed to liquidate.

We had a lot of fun, and I managed to net about $250 from the stuff I sold. More importantly, though, I met some great people. One fellow came up to me to thank me for publishing my study guides. I always enjoy meeting readers, and as always, I told him to call me should he ever hear me on the air.

Another fellow, who purchased a copy of my Tech study guide, mentioned that he had let his Extra Class license expire and now wanted to get back into the hobby. I told that should be easy enough, now that all he is required to do is to pass the Tech test. In addition to selling him the book, I gave him my card and told him to contact me if he had any questions about any of the material.

Towards the end of the event, a kid I guess to be 15 or 16, came up to the table with his father and expressed some interest in the RD-5R DMR radio and another analog HT that I had. I had priced the RD-5R at $25 and the other radio at $10. He shyly said something like, “I don’t want to offend you, but would you take $22 for both radios?”

When I replied, “Well, how about $25 for both of them?” he said, “Well, I only have $22 left.”

At that, his father said, “I’ll front you the extra three dollars,” and pulled out his wallet. And, as it turned out, the kid only had $21, so the total sale amounted to $24. Paul, Rick, and I got a laugh out of that.

As he collected the radios, I asked him what his call sign was. He replied that he hadn’t gotten his license yet, but he was going to take the test soon. I gave him my card and told him to make sure to get a copy of my free study guide. And, once he gets his license, to call me if he ever heard me on the air.

I was about his age when I went to my first ham radio swap meet. I hope that he has as much fun with ham radio as I’ve had over the years.

Hamvention 2023 was a blast again (Part 1)

May 23, 2023 By Dan KB6NU 7 Comments

Writing about an event like Hamvention is a daunting task, which is why I put off doing it. What I’ve decided to do is to cover it in several post instead of one big post. Here goes…

Driving to Dayton

I’m really fortunate in that it takes less than three and a half hours for me to drive to Dayton. I have even left very early in the morning some years to avoid having to pay for an extra night in a hotel room.

This year’s drive was very pleasant. The weather was great (as it would be for the entire Hamvention), and there was very little construction along the way to delay me. I left about 9:00 am and arrived at the Greene County Expo Center about 12:30 pm.

Along the way, I listened to podcasts. My listening habits are quite eclectic. The podcasts that I had downloaded for the trip included:

By the way, I use the AntennaPod podcast app on my Android tablet to manage my podcast subscriptions. It’s a great open source app. I’ve even donated to the developers to encourage them to continue developing and improving the app.

Poor band conditions :(

In recent years, I’ve had either an exhibitor badge or a forum presenter badge, which gives me access to the fairgrounds before the general public. I really enjoy wandering around the fairgrounds and watching Hamvention take shape. One of the stops I always make is the Linux in the Ham Shack booth to kibitz with Russ K5TUX, Sheryl W5MOO, and Bill NE4RD.

After I’d harassed them enough, I decided to set up my KX-3 out in the flea market and try my luck on the bands. There’s a great spot underneath a couple of trees there. Last year, I had great success operating from that spot. This year, not so much. The bands were just terrible, and I gave up after scratching out just two contacts.

After wandering around a bit more, I decided to head over to the hotel, check in, and have some dinner. I also caught a short nap before heading over to the QRP-ARCI Four Days in May Vendor Night.

Two new radios at Vendor Night

There were two radios that people seemed to be excited about there. The first was QRP Labs QMX 5-band digital transceiver. The QMX features include:

80-meter, 60-meter, 40-meter, 30-meter, and 20-meter bands
5W output
embedded SDR receiver,
24-bit 48 ksps USB sound card
CAT control
synthesized VFO with TCXO reference

The QMX can only run CW and single-tone FSK modes currently, including everything in WSJT-X, JS8Call, some fldigi modes e.g. RTTY, Olivia and more. On CW, the QMX has click-reducing RF envelope shaping. It is not suitable for phase shift keyed modes such as PSK31 or modes involving multiple concurrent tones such as WinLink.

The price is only $95! It’s kind of amazing that QRP Labs can offer these kits for that price.

The second radio was the sBitx v2 from HF Signals, home of the μBitx. This radio costs $500, but it is completely assembled and outputs 40 W. Other features include:

Modes: FT8, SSB, CW, RTTY, PSK31 and others out of the box (no computer required)
Compact 10″x 6″x 2″ size, slips into the backpack
Raspberry Pi inside, all preconfigured software & source code on-board
Hackable, tinkerable, scriptable
Integrates logging, logbook, spotting in one compact box
High Performance Hybrid SDR with passive front-end
Brick wall crystal filter 8 crystals
Fully electronic T/R and band switching
Open source, documented
Can be powered from an external 11.1v LiPo batteries for field ops

This looks like it could be a fun radio to play with. I like the 40W output capability and the open source software. I may have to buy one of each. :)

That was about all I could handle for one day. After vendor night, it was back to the hotel to crash and get ready for Friday at Dayton.
