Three Generations of CW Ops: Battleship North Carolina Activation and a Family Legacy

12 Comments

by Micah (N4MJL)

It’s not every day that I get the chance to do a POTA activation from the radio room of a battleship. But thanks to the Azalea Coast Amateur Radio Club, I was able to do a POTA activation of US-6831 from the radio room of (BB-55) USS North Carolina in Wilmington, NC.

If you would like the chance to be a guest radio operator for the BB-55, check out http://ac4rc.org to set up your activation.

The below-deck self-guided tour takes you through Radio Central. The radio room that the radio club utilizes can be seen from Radio Central; however, it is separated from public access by a clear plexiglass bulkhead door. Because the public can watch from the other side of the glass, be aware that it can be very noisy.

To make things more distracting, there is a loudspeaker in the radio room central playing pre-recorded Morse code for ambiance.

Radio Central is located a couple of floors down in the belly of the iron-armored beast, so be sure to schedule your activation on the POTA page. There is no cell phone reception below decks.

The radio club has an IC-756 Pro III available for use. I am not sure about the status of the other WWII vintage radios. I definitely recommend you bring your own key! They had a Bencher paddle thrown in the filing cabinet; it was not usable due to the contacts being bent way out of position. Fortunately, I brought my BaMakey TP-III key with me. If you are using a 3.5mm stereo plug, make sure to bring a 1/4” plug adapter for use with the IC-756 key/headset jacks.

The radio club has the IC-756 and external tuner hooked up to one of the battleship’s original long wire antennas. During the activation, I only operated on 20M. I did attempt to tune 17m and 15m, but I was unsuccessful in getting a match. However, that may have been operator error on my end since I was unfamiliar with the radio and that particular external tuner.

After a minute or so of calling CQ, the Reverse Beacon Network did its magic, and I was blown away by an insane pileup. I realized that I am used to operating QRP with somewhat compromised antennas. In sheer panic, I started looking to see how to turn the power down from 100 watts to, say, 2 watts!!!!

In that moment, I saw a vision of a seasoned Navy Radio OP sitting beside me. He reached over and smacked me on the back of my head and said, “Listen, kid, you’re not some hippie tree hugger operating QRP on some windswept mountaintop. You are operating from the battleship USS North Carolina. She has participated in every major naval offensive in the Pacific area of operation during WWII. Now stand tall, run full power, and work ’em all!”

With that old-school counseling session complete, I began to work the pileup. After being on the air for one hour and fifty-three minutes, I worked 67 stations, with two duplicates and one busted call sign (that I know about). Eventually, no one responded back to my CQ, and I sent “Last call fer POTA de N4MJL” twice. After no one responded to my second message, I quickly sent QRT and started breathing again!!!!!!

In addition to working SA4BLM from Sweden, one of the coolest contacts I got that day was from my dad, AC0UT, located in Missouri.

It’s not every ham that can say that their dad called them using CW while on a battleship.

CW actually runs in my family. I am a third-generation CW op. Continue reading Three Generations of CW Ops: Battleship North Carolina Activation and a Family Legacy →

QRP with Friends: Brian (K3ES) Joins Me for a Two-Fer POTA Activation!

3 Comments

On the activator side of things, Parks On The Air is often a solitary pursuit for me. I typically squeeze in activations as my schedule allows—usually at random times during the day in parks that happen to be along my daily route.

But every once in a while, the stars align and I get the chance to activate with a friend. When that happens, it only amplifies the radio fun. Saturday, March 22, 2025, was one of those special days. My dear friend—and frequent field report contributor—Brian (K3ES), along with his amazing wife and photographer, Becky, stopped by Asheville en route to the Outer Banks.

I was so happy everything came together and we were able to meet up for a short, relaxed, and thoroughly enjoyable activation.

Two-Fer Time!

When out-of-state activators come through the area, I always try to offer them the option of a two-fer—activating two parks at once—to maximize their POTA opportunities. I’m not sure Brian had strong feelings about this either way, but it was simply too easy to pair the Blue Ridge Parkway (US-3378) with the Mountains-to-Sea Trail (US-8313). Since we were meeting at the Folk Art Center, all it took was picking the right picnic table near the MST.

In my rush to leave the QTH that morning, I realized halfway down the driveway that I’d forgotten to pack my antenna. I could’ve turned around, but I knew Brian would have a few antenna options stowed in his field kit—and of course, he did!

He chose to deploy a homebrew end-fed random wire with a 29.5’ radiator and 17’ counterpoise. We paired it with my Elecraft K1 transceiver–a radio I knew Brian had never operated.

The only drawback of this particular picnic table is its proximity to the Mountains-to-Sea Trail. When deploying a wire antenna, you have to be careful not to obstruct the path for hikers. We positioned the wire in a near-vertical configuration above the table and kept the throw line tucked away on the opposite side from the trail.

We were also quite conspicuous—another reason I usually avoid this picnic table when activating solo. On a busy day, it’s not unusual to have a dozen people stop by to ask what you’re up to. It’s a great outreach opportunity, but a string of interruptions can make it difficult to complete exchanges—especially while sending CW. Sadly, my internal CPU isn’t optimized for multitasking!

Right to Left: Brian (K3ES) and Thomas (K4SWL)

But when there are two of you taking turns at the key, it works beautifully—one person can handle the questions while the other shows just how cool Morse code still is in the 21st century.

It was a fairly quiet day at the Folk Art Center, but one curious family did stop by to chat with us during Brian’s turn at the key—and I really enjoyed the interaction.

Philip’s Field Impressions of the Xiegu G106

5 Comments

Many thanks to Philip (KA4KOE) who shares the following report:

Xiegu G106 Report

by Philip (KA4KOE)

Recent developments and other drivers pushed me to purchase a Xiegu G106.

This radio has dropped significantly in price recently. I figured, “Why not?!” given the paltry sum Radioddity was asking.

I will not delve deeply into the technical aspects of this radio, as others have covered this subject in great detail. In my opinion, the G106 is a viable QRP radio and excels at CW and FT8. I also made contacts using SSB, but given the lack of speech processing, I found the effort, shall we say, challenging. The firmware on my particular radio is Version 1.3.

I checked the spectral purity using the panadapter on my Flex 6300. I realize the Flex is not a lab-quality instrument, but the serious spurs and other trash around the carrier, noted by others, on a 5-watt CW signal appear to be minimal now and compliant with current FCC regulations.

Some get all caught up in demanding the absolute best specifications, performance, looks, etc., or whatever you find important in your personal metrics for a radio. As an engineer, I approach this philosophy from a different mindset. Often, striving for those final few percentage points of improvement is only noticeable under the most stringent of band conditions. The situation is essentially a cost/benefits analysis. So, my personal rationale is “good enough.”

Indeed, the Xiegu G106 is “good enough” for QRP field activations, provided one also deploys a good antenna. Here’s an analogy: will a steel sledgehammer or solid gold one (ignore gold’s softness in this example), of the same mass, both do the same job? The answer is “yes.”

The only issue I have noted, as have others, is that the radio’s AGC recovery isn’t quite correct. Occasionally, the audio will “pop” when switching from transmit to receive. Hopefully, the G106 will improve if Xiegu issues firmware updates beyond Version 1.3. The radio doesn’t exhibit this annoying behavior every time one switches from TX to RX.

I recently activated US-2190, Magnolia Springs State Park, near Augusta, Georgia.

Band conditions degraded over the course of the day due to coronal holes present on the earthward-facing side of the sun. I did manage to make 25 CW and 8 SSB contacts on 40 and 20 meters using a sloping 40–10 meter N9SAB End Fed Half Wave, supported on one end from a 32’ carbon fiber pole. See the QSO map below:

Here’s my activation video:

Bottom line: I like the G106.

Thank you for your kind consideration and attention.

Experimenting My Way to the POTA Kilo Award

8 Comments

by Thomas (DM1TBE)

Some time before Easter I noticed that I am close to 1000 QSOs at my favourite place at the “Kalte Feld”, a POTA and SOTA activation zone and would soon qualify for the POTA Kilo Award. I like the Kalte Feld for the quiet, spacious area with a hut that is vending traditional basic food and beverages – which in Germany usually means good beer and different sausage types (and other stuff – to be fair). I already wrote some articles about the history of the area and my activations.

The conditions at the activation zone are quite good. I have made 2 activations there with more than 100 QSOs (and many smaller), so I thought it should not be too difficult to complete the required QSOs in one day.

DAY 1

The weather for the Easter weekend was expected to be one of the first warm and sunny days this year. So, on Easter Sunday, I headed to the area to get the last missing 49 QSOs for my POTA Kilo Award. Easter hiking has a centuries long history in Germany. This and the nice weather made the area quite crowded. The close airfield for gliders was busy and the whole time while operating there they were in the air above.

The barbecue places and outdoor seating around the mountain hut were busy but happily the bench some meters away that I am normally using, was still available.

I wanted to start with an end-fed half-wave antenna for the 20m band, tied to a 10 meter (33 ft) fiberglass mast. This is a very easy and quick to deploy antenna and I like it, especially if there is not too much space for antennas with a larger footprint. Since it’s a straight vertical, it also has a higher chance for DX contacts – when the conditions allow that. The antenna is Open Hardware and you can find further details on GitHub.

The mast was tied to the bench and the antenna was raised. Besides the comfort, the possibility to tie a mast to it is the second reason why I am always looking for benches.

The conditions were far from being perfect, and it took me 40 minutes to get 18 CW QSOs on the 20-meter band. Switching to SSB wasn’t a big help either, and I soon gave up with only 3 additional SSB QSOs in the log.

I had brought another antenna with me that I wanted to try. The 10 meter (33 Ft) fiberglass mast also has the perfect height for a ¼ wave vertical on the 40-meter band. So I cut 5 wires to a length of about 10 meters (33 ft) and connected 4 of them together at one end with a cable lug and attached another cable lug to the vertical element.

I then used the basis of the JPC-7 antenna for the coax plug and for connecting the vertical element and the radials. There are a lot of articles and videos about ¼ wave vertical antennas. But the information is usually about either elevated and resonant radials or random length ground radials. I wanted to have resonant radials, but I could not be bothered with carrying all the stuff nearly 2 miles to a summit for elevating 4 x 10m (33 ft) wires, so I simply left them on the ground.

My idea was to try a full size vertical for the 40 meters band with resonant radials that still is portable and fits to my existing equipment.

The SWR was quite nice being close to 1.0 : 1 at the CW portion of the band, so I started operating.

The conditions were similarly difficult as on the 20-meter band. It took me 25 minutes for another 18 QSOs.

As it became increasingly cloudy, I checked on my mobile and saw that rain was approaching fast. Since I had roughly 2km or 1.5 miles descent ahead of me, I stopped abruptly with just 10 QSOs short of the POTA Kilo Award.

A bit disappointed, I called it a day.

DAY 2

I could not leave the missing 10 QSOs for long. The very next day, Easter Monday, was a public holiday in Germany. And as the weather started nice, I again made my way to the activation zone. Continue reading Experimenting My Way to the POTA Kilo Award →

From the Badlands to Mesa Verde: QRP Across America’s National Parks

Activating on the Road:  National Parks

by Brian (K3ES)

This article continues my series from our 2024 road trip across the United States (Six Weeks and 7300 Miles:  Activating on the Road).  I hope to wrap up the series with one last article soon.  In this report, I will cover the six National Parks (NPs) that we visited during our trip.  I activated five of them for the Parks on the Air (POTA) program using CW mode at 5 watts.  A previous report on Stealth Activating with the KX1 Antenna System provided activation details for three of the parks (Badlands NP, Yellowstone NP, and Grand Canyon NP), so I will not reproduce activation details here, but I will include more of Becky’s pictures.

Each of these NPs is spectacular in its own right, and also distinctly different from each of the others.  We were able to see some of the sights, but by no means had enough time to do them justice.  In fact, as we completed our drive through Yellowstone NP, Becky and I committed ourselves to going back again and spending much more time to see its wonders.

As I reflect on our visits to NPs on our trip, it occurs to me how beneficial it was to buy an Annual America the Beautiful National Parks and Federal Recreational Lands Pass before we left on our trip.

The pass costs $80 for a year, and generally covers the admission of one vehicle and its occupants.  We were able to save on admission costs several times over, making this one of the best NP values going.  Having now completed 62 trips around the sun, when we next visit NPs, I am eligible for an even better value, the $80 Senior Lifetime America the Beautiful Pass.

Badlands NP

The first NP we visited on our trip was Badlands NP in South Dakota.  We spent a couple of nights and days based nearby in the town of Wall, so we were able to take two drives through the park.  There is a stark transition from rolling plateau north of the park to the spectacular peaks and canyons of the badlands.  Rapid erosion has been shaping the terrain for about 500,000 years with the Cheyenne and White Rivers cutting their way through the terrain.  The resulting landscape is both beautiful and severe.

While visiting the park, we were privileged to see a variety of wildlife.  We saw a number of bison, ranging from small herds grazing in fields along the road, to an individualist who took a liking to the taste of grass beside one of the overlook parking areas.  There were also bighorn sheep and pronghorn antelope wandering other parts of the park.  There was abundant bird life, from a disoriented prairie chicken that accepted water from concerned visitors, to birds of prey soaring high above.  Becky particularly enjoyed the frenetic activity of the residents of Roberts Prairie Dog Town.

This bison had no problem napping in the middle of the Prairie Dog Town
This prairie chicken appreciated shade and water in the parking lot

During our visit, we stopped at an overlook parking area for Becky to take pictures of the spectacular scenery, including the aforementioned bison.  While she was doing this, I took the opportunity to do a stealth activation of the park, which is documented in an earlier Field Report here on QRPer.com, linked as K3ES:  Stealth activating with the AX1 Antenna System.

I managed to catch the photographer in action during a lull in my activation
Of course, Becky caught me in action, too

Yellowstone NP

We knew when planning our trip, that we would not have time for a proper visit to Yellowstone NP.  In fact, we intended to hold off on visiting until we had time for a dedicated trip.  But throughout our drive, Becky kept searching the available maps for opportunities and possibilities.  As we traveled through Montana, she noticed that we could fit in an abbreviated trip through Yellowstone and Grand Teton NPs if we adjusted our route.  Consequently, we found ourselves spending the next night in Gardiner, MT, just outside the north entrance to the park.

First Field Outing with My New-to-Me Elecraft K1!

4 Comments

In the chaos of the past two months, I managed to post a few field reports out of chronological order. I’m probably the only one who notices—these aren’t sequential stories, after all—but since I was there for each activation, it feels odd when the timeline’s off.

Case in point: you might recall this recent post where I shared how I finally landed an Elecraft K1 field-portable transceiver. I’d been hunting for a K1 for years, so I was thrilled when this one popped up locally in North Carolina.

Last month, I published this field report where I paired the K1 with my AX1 antenna for a low-profile (but high-performance) activation in Pisgah National Forest.

But here’s the thing: that was actually my second activation with the venerable K1. The first one? It took place along the Blue Ridge Parkway on February 24, 2025.

Taking the K1 to the Field!

It’s always exciting to take a new radio to the field—especially one I’d been chasing for so long. I purchased the K1 back in August of last year. As soon as it arrived, I tested it and realized it was in serious need of alignment.

I brought it over to my friend Vlado (N3CZ), hoping to use his signal generator to sort it out. Unfortunately, we didn’t have time that day, so I left the rig at his QTH. Then Hurricane Helene hit, and… well, suddenly it was 2025.

We finally got around to the alignment in February. As soon as it was dialed in, I hit the field.

Blue Ridge Parkway (US-3378)

I made my way to a familiar spot along the Blue Ridge Parkway—the Folk Art Center—and set up the K1.

Mine is a four-bander (40, 30, 20, and 15 meters) with both the optional internal ATU and AA battery pack. To give the internal tuner a little workout, I paired it with my trusty Tufteln 9:1 End-Fed Random Wire antenna.

Once deployed, I hit the ATU button, and the K1 quickly found a solid 1:1 match. With logs at the ready, it was time to hit the airwaves!

Field Report: N2YCH’s POTA Activation with a Magnetic Loop Antenna

17 Comments

By Conrad Trautmann (N2YCH)

I tried using an Alpha Antenna 100w 10-40m mag-loop antenna for a POTA activation. I operated on FT8 so I could monitor where my signal was being received by using the PSKreporter.info real-time signal reports from stations that spotted my transmission. I really didn’t know what to expect or how a loop antenna would perform in the park compared to a vertical or wire antenna. Did it work? You bet. Would I recommend it? I’ll share my observations and results below and let you know at the end.

I bought this antenna used on QRZ.com’s swapmeet. It was clear to me upon receiving it that the prior owner had taken very good care of the antenna. I set it up on my patio for a quick test before heading to a park.

Mag Loop Test from the N2YCH QTH

It sets up quickly. The tuning is a little challenging to learn at first but there’s no doubt when you get it right, since the received signal is easy to peak once you find resonance. The tuning knob has three turns from 40m up to 10m. Moving it slowly from the bottom of the HF band up to the top, you’ll find the sweet spot and you can peak the received signal on your radio’s S-meter. I checked it with my RigExpert antenna analyzer and as you’d expect, the bandwidth was very narrow, but it was resonant and the SWR was 1.4:1.

The Alpha mag loop can do 100 watts SSB but only 5 watts on digital modes. I fired up my KX3, set it for 5 watts and called CQ. I made three quick contacts and was satisfied that the antenna was working. I checked the spots on pskreporter,info and found it interesting to see a narrow band of stations from Minnesota and Wisconsin down to Florida spotting me.

Pskreporter.info map of spots from Mag Loop

On to the park: Indian Well, US-1684 in Shelton, Connecticut

Knowing that the antenna was working, I brought it out to one of my favorite places to activate, Indian Well State Park (US-1684). Again, set up was fast and I was able to tune up on 20 meters pretty easily.

Alpha Magnetic Loop Antenna at Indian Well State Park in Connecticut

The antenna was receiving the FT8 signals at S-9 with the KX3’s pre-amp off and you can see below that I was decoding nearly 50 stations per FT8 cycle. If you look closely at the JTAlert screenshot below, you can see I was receiving stations from all over the US as well as Canada, South America and Europe. There’s no doubt the mag-loop can hear very well.

Forty-seven stations are being received and decoded. POTA stations in the bottom right pane

I called CQ and had a few responses right away. However, I was finding it challenging to get stations to reply. It took almost an hour for me to get my 10 contacts to activate the park, which is unusual. I should mention that the space weather was acceptable, sitting just below Kp3, so that wasn’t the reason.

Once again, I checked Pskreporter.info. Interestingly, it had the same pattern of spots that I saw when testing the antenna at home, a band from Minnesota to Georgia. Of the first 10 contacts I made, four were in North Carolina, two in Florida and the rest were coming from within that narrow band who could hear me.

Spots from US-1684 using the Mag Loop

I understand that a mag loop is directional, so I tried moving it 90 degrees to see if it made a difference. Not really. The spot map looked the same after the change in direction. I was able to receive a few more EU stations after I moved it. I did have to re-tune the antenna after I turned it, the SWR had gone through the roof.

For comparison, after struggling to make contacts on the loop, I decided to set up my “go-to” antenna of a 17’ telescoping whip on a 10’ mast with a counterpoise.

Buddipole with 17’ telescoping whip and elevated counterpoise

I unplugged the mag loop and plugged in the vertical using the same transceiver set at 5 watts. Take a look at the stations who could spot me on PSKreporter now…

PSKReporter Spots with vertical antenna on 20m QRP

Clearly, that same 5 watts from the KX3 had better coverage on the vertical than using the mag loop.

Here’s a screenshot of WSJT-X on the vertical (click image to enlarge):

WSJT-X and JTAlert reception using 17’ vertical with counterpoise

Once I switched to the vertical, I knocked out 10 more contacts in just 20 minutes.

So, after all that, what do I think?

The Mag Loop sets up quickly, uses very little space and finding resonance isn’t difficult to do. It receives very well, of course this is one of the true advantages of mag loops, is their inherent ability to receive well in noisy environments.

As an antenna to use for transmission? Well, I think this is where the challenge lies, for me anyway. It was certainly hearing stations way down in the noise from far away. However, as you can see by my real-time reception reports, it did not give me the wide transmission coverage that I’m used to with the vertical. Maybe this would be different on SSB with 100 watts, but it’s a difficult to measure SSB reception like you can with digital.

Can you activate a park with it?  Yes, indeed. Would it be my first choice for POTA? Probably not. If you were using this on SSB, the antenna itself (not the radio) would need to be re-tuned for every frequency change (if you were hunting), which is not convenient. If you are the activator, then you could tune up for the frequency you selected and it would be good to go.

My next test with this antenna is to try tuning it to a WSPR frequency and comparing spots it receives to my other antennas. I suspect this it where it will shine.

Stay tuned!

The POTA Babe Loses Weight

9 Comments
By Teri KO4WFP

I love living in the state of Georgia. The state contains diverse natural spaces – mountains and valleys in the north, rolling hills and forests in the middle, and a plain extending to the coast with wetlands, marshes, and forests.

source: Georgia DNR
source: GA DNR

The Georgia State Parks on the Air event celebrates and draws attention to state parks scattered throughout these spaces. For this year’s event (April 5th and 6th), I signed up to activate George L. Smith State Park (US-2179), a park located a little over an hour from my home. I’ve activated this park several times in the past – for POTA as well as the K2D special event.

To do something different and to qualify for the hike-in bonus (100 points) for the event, I planned to hike the Deer Run Trail. This trail runs past the historic mill on site and through a wooded area on the southeast corner of the park. To qualify for the bonus, I had to hike at least 1 mile from my vehicle so I walked a section of the outer loop trail.

The hike was pleasant. Daisy and I walked through a forested area bordered by cypress bottomlands and farmland. Several benches along the path offered hikers a quiet place to relax. I was surprised by how many people we encountered.

the trail is well marked

We finally reached the junction of the loop and .7 mile trail, the latter having a power line running along it. Here was another bench set admist a mixture of pines and hardwoods. A tall pine directly across from the bench had a branch about 30 feet high, just perfect for the dipole antenna I brought, that is if I could reach it.

I removed my throw bag, arbor line, and throw weight, and tossed the line to see how close I could come to that branch. My line and weight ran over a broken branch forming a notch about 10 feet lower. I tugged to remove them and stared in amazement when the line abruptly broke free and fell at my feet…WITHOUT the weight attached. Oh crap! I was so gung-ho to nail that branch that I forgot to securely tie the weight to the line. (doh!)

my throw weight lodged in the notch

I stared in amazement, my mind slowly processing my situation. I did not bring an additional weight because I stopped carrying it since I never needed it (until now that is) and wanted to travel light for today’s hike. Shoot! Now what?

I spent the next 15 minutes trying to find a branch long enough to reach that spot as well as throw sticks at the weight. Nothing came close to dislodging it.

Well, I could just throw in the towel. But POTA Babes don’t give up that easily. I had an obligation to the event as I signed up to activate this park and hunters would be looking for me.

The only items in my pack I could attach to the arbor line and throw were an insect repellant bottle and my Nalgene water bottle. The insect repellant bottle I rejected because of its spray trigger which could definitely get stuck on a branch. But the Nalgene bottle might work. Daisy and I drank some water to lighten it. I tied the arbor line to the lid, found a branch about 15 feet up in the air, and tossed the bottle. Would this even work?

Nalgene bottle

It did! I know you antenna purists out there are shuddering. However, I figured a lower antenna was better than no antenna at this point. I brought two antennas with me for this activation: the Tufteln EFRW and a home-brew linked dipole I built roughly three years ago. A dipole is an amazing antenna, even if homebrewed. I figured my signal needed all the help it could get with the lower height and power lines nearby so I chose to use the dipole.

homebrew linked dipole antenna (40-30-20 meters)

Daisy and I settled across the trail in the understory to shade ourselves from the sun. One leg of the dipole ran across the hiking trail. To give the antenna as much help as I could, I secured both ends of the dipole roughly 6 feet up in foliage. Where it crossed the trail, it was high enough anyone would pass easily underneath it.

I took a breath, pressed the ATU button to activate the internal antenna tuner, cleared a frequency, and began calling CQ. I had no idea what to expect. Continue reading The POTA Babe Loses Weight →

Ham Radio Workbenches On The Air Field Report: Part 2

1 Comment

As promised, here’s Part 2 of my extended HRWBOTA activation report from March 16, 2025!

(US-6856)

As I mentioned in Part 1 of this activation, I’d planned to operate for the full four-hour window of the March 16th Ham Radio Workbenches On The Air (HRWBOTA) event—a rare luxury for me. Most of my field activations typically last anywhere from 30 to maybe 90 minutes at most. So, sitting in one spot and operating for four full hours definitely stretched me a bit—but in a good way!

After two hours of non-stop CW with the Elecraft KX3, I took a brief break, swapped radios, and continued the activation with my Penntek TR-45L.

This portable rig is one of my favorite minimalist CW transceivers, and I thought it was a perfect fit for the second half of the HRWBOTA event. I used it to work 20, 30, and 40 meters in CW (in that order).

One nice bonus of using the TR-45L is that mine has a built-in Z-match ATU, which allowed me to easily find a match on 30 meters, even though the Spooltenna EFHW isn’t resonant on that band. The antenna was the same excellent 40-meter EFHW prototype from Rob (KO4HUI) that I featured in Part 1.

The only other minor change during this segment of the activation was behind the camera. Since I was filming in real-time for four straight hours, I had to pause at one point to connect my action camera to a portable battery pack which then limited my ability to use wireless microphones with wind screens. The gusty wind will be more noticeable in this portion of the activation video as a result—but, hey, it’s all part of the field experience!

Now, let’s dive into Part 2 of the gear and activation details…

As I mentioned in Part 1, this was a longer activation, and since I needed to submit electronic logs to HRWBOTA admin Mark (N6MTS), I skipped paper logging—a true rarity for me.

Instead, I logged directly into AC Log on my Microsoft Surface Go, just as I would during Field Day.

During this second part of the event, I started on 20 meters and spent a little over an hour working a steady stream of contacts. Continue reading Ham Radio Workbenches On The Air Field Report: Part 2 →

Ham Radio Workbenches On The Air Field Report: Part 1

6 Comments

Many of you likely know that I’m on the crew of the Ham Radio Workbench podcast and that, in December 2023, we hosted the first Ham Radio Workbenches On The Air (HRWBOTA) event.

Unfortunately, I had one scheduling conflict I couldn’t change, which meant starting the event with my KH1 in a downtown Asheville parking lot before heading to Lake James State Park for a couple of hours of solid pileups with my Icom IC-705. I posted a field report and video of the event—it was a blast! Click here to check it out.

On March 16, 2025, we held our second HRWBOTA event, and this time, I was better prepared with a clear schedule and a plan to operate for the full four hours!

Zebulon Vance Birthplace (US-6856)

Of course, even the best-laid plans can run into hiccups, and mine did. I was delayed due to some chainsaw work I wanted to complete before leaving home. As a result, I arrived at US-6856 just as the event was starting (14:00 local).

No worries, though! I turned on the camera and wasted no time deploying my antenna and setting up my radio gear.

The Spooltenna!

For this activation, I used a prototype of the Spooltenna, designed by Rob (KO4HUI).

Rob, a fellow North Carolinian, had been in touch with me about his antenna idea for months. Back in February, when my daughter interviewed for a scholarship at NC State University (which she was later awarded!), I met up with Rob on campus, and he handed me an early prototype of the Spooltenna. He had just completed the build that very morning.

It’s a unique design based on his own needs for a field antenna. From his website:

SPOOLTENNA is a compact, lightweight antenna designed for portable amateur radio operations like Parks on the Air® (POTA) and Summits on the Air™ (SOTA). Its innovative spool form factor is intended to ensure efficient deployment, teardown, and storage, providing a frustration-free operating experience that doesn’t compromise performance.

The design is also Open Source under a Creative Commons Attribution-ShareAlike 4.0 International License.

The Spooltenna he gave me is a 40-meter end-fed half-wave (EFHW). Before this activation, I had only set it up at home to check resonance on 40, 20, 15, and 10 meters. I deployed it as a sloper, with the transformer at the highest point.

The Spooltenna is quick to deploy–by placing a pencil, tent stake, or screwdriver in the center hole–and the spool design ensures a tangle-free wind-up. The components feel very high-quality. Rob is also producing high-quality cable assemblies, which were included in the package he gave me.

Rob has rapidly turned this idea into a side business involving his whole family. In just two months, his wife Christi has launched a website, ordered inventory, and—just a week ago—even set up an affiliate program and coupon code offering free shipping to QRPer.com readers.

Rob will be at the Raleigh Amateur Radio Society hamfest this weekend. He plans to attend FDIM and Hamvention in Dayton next month with inventory.

UPDATE: Rob tells me that he will have some inventory at RARSfest this weekend and will even temporarily open up his website for Spooltenna orders tomorrow (Saturday, April 4, 2025) during the RARSfest. 

Again, I’m most impressed with all that he and his wife have accomplished in a few months.

Deploying the Spooltenna was easy, though I had to adjust my setup. I originally planned to support the transformer with a tree next to the picnic shelter, but that tree had been blown down during Hurricane Helene.

No worries! I set it up as a sloper with the transformer close to the ground—similar to many of my EFHW deployments.

My HRWBOTA Activation Plan

I planned to use two radios during this activation—first my Elecraft KX3, then my Penntek TR-45L on the lower bands.

To maximize the chance for HRWB listeners to work me:

  • I did not spot myself on POTA.app, even though I was giving all contacts POTA credit. I knew that if I spotted myself, the normal weekend POTA pileups might make it harder for HRWBOTA participants to contact me.
  • I started on 10 meters and slowly worked my way down.
  • If time allowed, I planned to work SSB on at least one band (spoiler alert: CW kept me too busy!).

First up was the Elecraft KX3! I set up the radio and wasted no time getting on the air.
