Overcoming Band Conditions: A Challenging (But Rewarding) POTA Activation at Scioto Trail State Park!

On the morning of Wednesday, May 15, 2024, I woke up, grabbed breakfast, and headed to Strouds Run State Park in Athens, Ohio. (You can read about that activation in my previous field report.)

Once I returned to Eric’s (WD8RIF) QTH, Eric, his son Miles (KD8KNC), and I packed up the car for the drive to Dayton—roughly 2.5 hours from Athens. En route, we decided on an activation of Scioto Trail State Park (US-1990) which also happens to be a two-fer with Scioto Trail State Forest (US-5448).

I’d hoped band conditions would remain as favorable as they were in the morning, but the sun had other plans! (Indeed, this would become a recurring theme throughout the following week.)

Scioto Trail State Park (US-1990) and Forest (US-5448)

We arrived at Scioto Trail around 2:00 PM, under scattered clouds and after passing through some rain. We hoped the weather would hold!

I’d never been to Scioto before and was pleased to see a small island on the lake accessible by a footbridge.  It had a gazebo, perfect for a POTA station.

Reunited

A highlight of this trip was giving Eric a chance to operate my Index Labs QRP Plus. Eric had owned one for 13 years as his first field radio. In fact, as I’ve mentioned before, when I first met Eric in 1997, it was while he was operating a QRP Plus during FYBO!

Since the QRP Plus is better suited for tabletop use, I recommended Eric set up in the gazebo.

I provided my Chelegance MC-750 for him to operate on 20M.

POTA in the Shade

I set up under a tree at the edge of the island—as far from Eric as possible to minimize interference. In reality, the island is small, so I was only about 15 meters away—not ideal!

The tree offered some shade and potential rain protection. I deployed my Helinox Chair, my “no-transformer, no feedline” Tufteln random wire antenna, the Elecraft KX2, and my Tufteln/N0RNM kneeboard.

When I turned on the radio, I could hear Eric’s signal bleeding through on 30 meters (a band I chose to avoid harmonic interference with 20M).

The KX2 is sensitive, so this wasn’t unexpected. Eric never experienced interference from my station, likely due to the QRP Plus’s less sensitive receiver.

On the air

This turned out to be an activation where I’d really put my KX2 ATU to work! Continue reading Overcoming Band Conditions: A Challenging (But Rewarding) POTA Activation at Scioto Trail State Park!

QRP POTA with Friends: Two Park Activations with VE6LK, NJ7V, WD8RIF, and KD8KNC!

Sunday, May 21, 2023, was the final day of Hamvention.

I traveled to Hamvention with my buddies Eric (WD8RIF) and his son Miles (KD8KNC). We decided in advance that instead of attending Hamvention that Sunday (after having spent all day Friday and Saturday there) we’d opt for a relaxing day playing POTA near Dayton/Xenia.

We weren’t, in fact, the only ones who skipped Hamvention that Sunday–our friends Vince (VE6LK or AI7LK State-side) and Charlie (NJ7V) did as well, so we decided to play POTA together!

Both Charlie and Vince were leaving the Dayton area that afternoon, so they needed to finish up their activations by noon at the latest. We decided we could fit in two activations that morning before Charlie and Vince headed back, then Eric, Miles, and I would hit a third park in the afternoon. Actually, Miles never planned to hop on the air, but he was both our ride and valuable POTA support!

Vince and Charlie in the rear view mirror!

Charlie and Vince met us at our hotel around 9:00 AM and we drove to the first of two parks we’d activate together.

The weather was beautiful that day, but the space weather, much less so. We knew in advance that it would be a struggle based on the propagation forecast and numerous reports from other activators.

Vince set up his Elecraft KX3-based station in the trunk/boot of his rental car.

He deployed his “low-slung” wire antenna (read more about that here) and hit the air.

Vince’s low-slung antenna

Eric described the POTA station he deployed in his field report on WD8RIF.com:

Eric found a shady, level spot near the parking lot, strapped his 31′ Jackite telescoping fiberglass pole to his folding camp-chair, deployed his 28½’ wire vertical on the pole, set up his Elecraft KX3 on the camp-chair’s flip-up table, and was on the air at 1412 UTC. Eric began his operation with a lovely touch-paddle which he had unexpectedly been given as a gift from the builder, Brian Manley, K3ES

Eric’s station

Note that Eric carefully documents each and every one of his field activations and field contests on his website. His field reports date back to Field Day in 1995!

I found a spot to set up next to the lake under the shade of a large tree. I deployed my Tufteln no-transformer 28.5 foot end-fed random wire.  This antenna is simply two lengths of 28.5′ wire: one wire for the radiator and one for the counterpoise. The KX2’s internal ATU does all of the heavy lifting. Continue reading QRP POTA with Friends: Two Park Activations with VE6LK, NJ7V, WD8RIF, and KD8KNC!

Why I’m skipping Hamvention this year

I made a tough choice a few weeks ago.

Since last year, I’ve been planning to attend the 2022 Hamvention and the Four Days In May (FDIM) evenings.

Hamvention weekend is one of the big highlights of my year and–until the pandemic–I hadn’t missed a single on in more than a decade.

I was really looking forward to this year if for no other reason than to connect with friends I only see at Hamvention.

My buddy Eric (WD8RIF), his son Miles (KD8KNC), and sometimes our good friend Mike (K8RAT) attend Hamvention together. We split accommodation, car pool, and fit in park activations before, during, and after. We also fit in an annual pilgrimage to the USAF museum. It’s incredibly fun.

As fun as Hamvention is–which is insanely fun–I realized that it was going to be a pricey 3-4 night excursion when I already have some pretty epic, much-anticipated travels planned this summer with my family.

Since I had literally no items on my Hamvention shopping list (Eric didn’t either) and since I wanted to funnel all of my travel monies into the amazingness that awaits us this summer, I had a hard time justifying the costs of the trip.

So I reached out to Eric who, turns out, was feeling much the same way.

We hatched an alternate plan that ended up winning us over. Continue reading Why I’m skipping Hamvention this year

Hamvention 2021 has been cancelled

The following note was posted on the Dayton Hamvention website:

Unfortunately, several setbacks in the recovery from the COVID-19 pandemic make necessary the difficult decision to cancel Hamvention 2021. Hundreds of volunteers have been working to do everything necessary to bring this Hamvention to the many amateur radio enthusiasts and vendors who support the Dayton Hamvention.

Vaccine distribution both in the United States and around the world is lagging behind what was planned. In addition, the emergence of a more communicable form of the COVID-19 virus increases the potential for further public health problems in the next few months. We make this difficult decision for the safety of our guests and vendors.

Those who had their tickets, inside booths or flea market spaces deferred last year will be deferred again. Those who purchased 2021 tickets, inside booths or flea market spaces will also be deferred. If you desire a refund instead please email [email protected] and we will contact you.

Stay tuned for information about a QSO party for the 2021 Hamvention weekend. We are looking forward to the 2022 Hamvention!!!

QRP Labs new QCX+ QRP CW/WSPR transceiver kit

Many thanks to Pete (WB9FLW) who writes:

Hi Thomas,

QRP Labs has just announced the QCX+ which as the name implies is an upgraded version of the very popular QCX line of transceivers

To date almost 10,000 kits have been sold, here’s a brief overview of the the differences and new features made to this popular Transceiver.

The QCX+ is the almost same circuit as the QCX, with two very minor changes. QCX+ runs the same firmware as QCX, and has identical operational and performance characteristics. QCX/QCX+ firmware will always be compatible with both the QCX and QCX+. The evolution of QCX to QCX+ provides several improved features in physical layout, as follows:

1) Physical layout of controls and connectors

2) Optional enclosure

3) Additional and changed connectors

4) More spacious PCB, more than double the board area, with less densely packed components, and more test/modification points

5) Improved heatsinking

6) Three minor circuit changes

7) No microswitch key

Price has gone up slightly to $55, still no other QRP Transceiver on the market today comes close to the features offered by the QCX+ at this price point.

More Info:

Thank you so much Pete! You’re an enabler! Since I’m not at Hamvention right now, those radio bucks are burning a hole in my pocket. The QCX+ looks like a fun transceiver to build! Thanks for the tip.

Missing Hamvention? Yeah, me too.

My friend Piero Begali (I2RTF) winner of the 2019 Hamvention Technical Achievement Award.

Note that I originally published this post on the SWLing Post:

If we weren’t all in the midst of a global pandemic, today I would be at the first day of the 2020 Hamvenion in Xenia, OH.

Since I would not be hosting a table for ETOW this year, I was going to Hamvention for the first time on Press credentials. While I absolutely loved hosting the ETOW table with my friends and fellow volunteers, I was certainly looking forward to being a bit of a free agent this year and visiting vendors and friends with no time pressures. This would have also given me much more time to do live postings.

For me, Hamvention is first and foremost an excuse to hang with good friends I only typically see once a year. Between Hamvention and several other associated events like the QRPARCI’s Four Days In May, I connect with hundreds of people. It can be a bit daunting–even draining to this “socially adept” introvert–but I still love it and look forward to it every year.

One of my favorite things to do at Hamvention is to see what new innovations individuals and companies have introduced. As I’ve mentioned before, I love the “mom-and-pop” innovators in our radio community and Hamvention is certainly one of those places where they showcase their goods.

Of course, I love the Hamvention flea market–easily one of the largest outdoor hamfest flea markets in the world. Although I have found some outstanding deals at the Hamvention flea market in the past–like my BC-348-Q ($40) and Panasonic RF-2200 ($70)–I’m more likely to find that obscure rig or accessory I’ve been looking for rather than a proper bargain.

This year, I would have kept my eye out for a Kenwood TR-9000 or TR-9130 VHF transceiver.

The Kenwood “Trio” TR-9130

I’ve seen the TR-9000 and TR-9130 at past Hamvention flea markets–a near ideal place to locate vintage transceivers like these. (On that note, contact me if you have one you’d like to sell!) 🙂

I would have also been on the lookout for classic shortwave portables, of course, and accessories like enclosures, antennas, Powerpole connectors, coax, ladder line, and wire. Many of these I would only buy new.

2020 might not have been a great flea market year anyway. The weather forecast calls for quite a bit of rain and possibly thunder storms over the weekend. Likely, the flea market grounds would have been a bit wet and muddy thus less vendors would have shown up.

See you next year!

Calling off Hamvention made sense this year. Even if state restrictions would have allowed for a gathering of 30,000 people, I imagine turnout would have been anemic at best. The typical Hamvention attendee also happens to be the target demographic of the Coronavirus. Many would have not wanted to take the risk. I doubt there would have much of any international attendees or vendors there either.

You can bet I’ll be at Hamvention next year and you can bet I’ve already started my shopping list! If the pandemic is no longer an issue, I willing to bet Hamvention might have a record year in 2021. I look forward to finding out in person!

National Parks On The Air (NPOTA) activations today

IMG_20160519_105823050_HDR

En route to the 2016 Dayton Hamvention, I’m doing a few National Parks On The Air (NPOTA) activations with my my buddy, Eric (WD8RIF).

Eric is currently the number one activator in the state of Ohio.

NPOTA is a great excuse to get outdoors and play radio.

For me, it’s a great excuse to test the LNR Precision LD-11 and my new QRP Ranger portable power pack.

IMG_20160519_101759179

I am loving the new QRP Ranger power pack–it is the solution I decided on after publishing this post a few weeks ago. It’s a little pricey, but it’s built like a tank, very lightweight, includes a charge controller made specifically for the LiFePo cells, and made here in the USA. It also had a very readable LED display that my buddy Eric says is, “reminiscent of the displays on the Apollo 11 module.” He’s kind of right!

It’s so nice to have both a volmeter and ammeter on the front panel.

IMG_20160519_111039495

 

We just finished activating the Hopewell Culture National Historical Park (I’m writing this post while Eric drives us to our next activation). I made 12 contacts running SSB at 8 watts. Eric made 16 contacts via CW at 5 watts.

We have planned two more activations this afternoon:

  • Charles Young Buffalo Soldiers National Monument at 16:30 UTC
  • Dayton Aviation Herital National Historical Park at 21:00 UTC

I’ll be calling CQ on 14.290 MHz and 7.290 MHz +/-.

Please hop on the air listen and/or answer my call if you’re a ham!

Of course, tomorrow through Sunday, you can find us at the Dayton Hamvention in booth SA0359 in the Silver Arena.

Hope to see you there!

The Ten-Tec Patriot: an open-source SSB/CW/Digital transceiver

507-Patriot-low-res

Today at the QRP ARCI conference, Four Days in May, Ten-Tec is showing off their latest open-source transceiver: the Model 507 Patriot.

507 Patriot 001

Building on the concepts behind the Model 506 Rebel, released last year, the Patriot is open-source and firmly targeted at the makers and experimenters amongst the amateur radio crowd. Like the Rebel, the Patriot is spartan by design, leaving it to the maker to develop the transceiver’s character via crowd-sourcing.

The Ten-Tec Patriot at my QTHUnlike the CW-only Rebel, the Patriot has SSB and digital modes in addition to CW.

Mic and line levels are adjustable by recessed pots on the right side of the Patriot
Mic and line levels are adjustable by recessed pots on the right side of the Patriot

The Patriot arrives as a fairly bare-bones 20/40 meter transceiver, but with all of the essential functions pre-loaded, including:

  • AF gain
  • RIT
  • Bandwidth selection
  • Tuning step selection
  • Band selection (20 or 40 meters)
  • Tuning knob/encoder
  • Mic Level
  • Line Level in/out
  • CW Speed

I’ve had the Patriot’s progenitor for about a week now, and have had it on the air a bit. But as this is a very early beta version, I can’t comment on much other than to say that audio reports have been quite good on SSB. I’ll dive into the digital modes after the Hamvention.

Ten-Tec Patriot

Of course, when I receive an actual production unit of the Patriot, I’ll give a more thorough overview.

In a nutshell?  I like this direction for Ten-Tec and am happy to see that they are growing a new line from the seed planted by the Rebel. By producing basic, open-source, and relatively affordable radios, Ten-Tec may actually be blazing a path to transceivers with benchmark performance and crowd-sourced firmware. I have no idea if Ten-Tec is contemplating this, but I’m sure many manufacturers are–it’s a great direction for any company.  Meanwhile, stay tuned for more on the Patriot!
