Conrad Tests the Elecraft AX3 at Silver Sands State Park

Elecraft AX3 Field Report

By: Conrad Trautmann (N2YCH)

My new Elecraft AX3 antenna arrived in the mail. The weather when it arrived was 73° F and sunny with a slight breeze. Space weather was calm.  It seemed like the perfect recipe for a POTA expedition to the unofficial antenna testing range at Silver Sands State Park (US-1716) here in Connecticut on the Northern shoreline of Long Island Sound to try out the AX3. Given that this antenna is specifically designed to be light and portable, I chose my Elecraft KX2 to pair it with, which is also light and portable.

The AX3 operates on six bands. Out of the box, it can do 30,20,17,15,12 and 10 meters. With the optional AXE1 adapter, you can add 40 meters as well. Elecraft says an ATU is required, which I have built into my KX2. I tested using FT8 on 30/20/17 & 15 meters, the four positions labeled on the front “jumper block.” Using FT8, I was able to use the PSKreporter.info website to get a sense of where my signals were being received. This antenna is capable of handling 30 watts, which is amazing for its size. I ran 10 watts from the KX2.

Unlike the AX1, which needs something to hold it in place such as a tripod or the optional bipod, the AX3 comes with three legs to turn the base into a tripod.

At the park, I tried using the legs which lasted all of 30 seconds before the Long Island Sound breeze blew it right over on its side. Anticipating that it might be too breezy down at the shoreline, I brought a slightly heavier tripod along. The good news is that the bottom of the antenna is tapped with a ¼-20 hole to connect to any standard camera tripod. The heavier tripod did the trick.

I used a three foot piece of coax as recommended and I had no problem with RFI into the radio or the computer. The KX2 was able to tune to 1.0:1 SWR on all bands except for 17 meters, which was right around 2.0:1. I should note that I had the 13’ counterpoise laying on the ground for this test.

I began on 20 meters and in 20 minutes, I had the 10 QSO’s needed to activate the park.

Next I QSY’d up to 17 meters.

Here, I had plenty of spots, yet I struggled to get two in the log before I gave up and QSY’d to 15 meters. Changing frequency is as simple as pulling the jumper block out and moving the arrow to the correct frequency.

Thankfully, 15 was open and my first QSO was with a station in Ukraine and my second was in California.

I made contacts on 20, 17 and 15 meters. Could I manage something on 30? I tried but to no avail. I was spotted by stations on PSKreporter, but after calling for some time, I figured that midday in Connecticut was just not the best time for that band. Before I packed up for the day, I went back to 17 meters which was definitely better than earlier and I logged three more for a total of five on the band.

I took the opportunity to go back to Silver Sands a few days later to try the antenna on 12 and 10 meters, which I did not do on the first trip out. I also wanted to see how elevating the counterpoise might affect the performance. It was downright windy, so I brought along a camera tripod this time to provide more stability. Obviously, the extra weight carrying a full size tripod wouldn’t be ideal for a SOTA activation, but for my test, I brought it along.

The high band propagation was miserable when I went out, I was wondering if I’d be able to make any contacts at all. I was pleased to see that elevating the counterpoise allowed 17 meters to easily match to the antenna with a 1.0:1 SWR. I then tried 15, 12 and 10 meters which also tuned right up and I made contacts on all bands.  10 and 12 meters were open to my south. I made QSO’s with Belize, Mexico, Ecuador, the Dominican Republic and Puerto Rico.

The AX3 did not disappoint.

Making QSO’s from California to the Ukraine and down into South America while sitting at a picnic table in a park in Connecticut with just 10 watts using such a small antenna is simply amazing to me. I like the AX1, which I used primarily on 20 meters. Having the multi-band flexibility of the AX3 is very nice, especially now that the upper bands are active, and it provides more flexibility for operating portable and being able to change bands on the spot to adapt to the ever changing band conditions.

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.

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!

First Look at the HF Signals zBitx QRP Transceiver

When life gives you lemons, you make lemonade!

by Vince (VE6LK)

Dear readers, it’s been a hot minute since I’ve had time to activate POTA and write about it, and today I tried to activate a park, but a combination of equipment issues and nobody responding to my calls ended my activation. Anyways … when life gives you lemons you make lemonade, and accordingly the activation article is now a radio review article instead! <grin>

That radio is the HF Signals zBitx. An SDR radio, it was spoken about at 2024 Four Days In May and it opened up for orders on December 25 2024 – a Christmas present, if you will. Thomas and I both jumped on the ordering queue (two numbers apart, no less) as well as 248 others around the world. I thought to myself “an all-mode 80-10m QRP radio with a waterfall and weighing under 1 pound for under $200USD shipped? SIGN ME UP!” and pressed the order button. Honestly I thought about it for less than 45 seconds once I read the specs. I also thought to myself that it was an “experimenter’s radio” and not a fully finished product, meaning you can tweak it if you wish to dig into the bowels of the code on the built-in Raspberry Pi.

The 250 original orders were snapped up in two days and then the purchase button was turned off on the website. There were some shipping delays from the original date, as HF Signals discovered the Chinese New Year holiday of 3 weeks where, it seems, everything is shut down. I also discovered this with the Morse Tutor Kits my buddy and I sell, and we couldn’t ship product for a month as we could not get parts.

The radio arrived on March 31, about 4 weeks beyond the original estimate, and I was excited to open it up. I mean, who doesn’t like new radio day after all? I was so excited that I did an unboxing and first look video on YouTube and showed off a few quick things about the radio. TOP SECRET – it took me 5 takes to shoot, so it wasn’t quite a first look!

The radio promises much and delivers a lot. It transmits on 80 through 10 meters at around 5 watts driven by a pair of 18650 cells, or your 6 to 9V four amp power supply. It has two microprocessors, one is a Raspberry Pi Zero W and one is a Pi Pico to drive the display. It has integrated AM, SSB, CW, FT8, touch screen, built-in electret mic, built in CW keyer and keyboard, and weighing just 460g / 1 pound including the batteries. This radio seriously has lots to offer especially at the price point.

The author’s radio with a customized faceplate and VFO knob. The triangular slice in the waterfall display is a photographic artifact.

The source code, schematics and 3D print files are all available on a Github, and indeed I customized the front panel and replaced the knob with one that has a dimple on it, if only to spin the VFO more easily.

You must be made aware that I was really excited to get this radio. It has a history of many other Bitx radios before it. But I’m also aware that there’s the old axiom about “too good to be true” so I tempered my expectations. You must also be made aware that I really want this radio to work as its small form factor, low cost and integrated waterfall make it exciting an exciting prospect in my limited fleet of QRP rigs. And, for the record, I have nowhere near the QRP rig count that our gracious host has, nor are they individually named.

Besides all of that, it is the only HF radio I plan to pack for Hamvention 2025 so it’s gotta be right for that trip.

However, the zBitx may be best described as an early release and/or a work in progress. Continue reading First Look at the HF Signals zBitx QRP Transceiver →

Magnetic Declination Matters: Tips from W7UDT

8 Comments

Azimuth Maps & Magnetic Declination Corrections in the Field.

by Randall Tom (W7UDT)

According to the USGS website (which is wrong!), in the United States, the current magnetic declination can be found below.

Here’s the USGS link:  https://www.outdoors.org/resources/amc-outdoors/outdoor-resources/what-is-declination/

Did you know that magnetic north changes over time?  And with that, magnetic declination changes over time!  The link below is from the organization Alpine Savvy.  Apparently, both have change dramatically.

https://www.alpinesavvy.com/blog/find-the-correct-declination-for-anywhere. 

Their website has a chart showing the change at Portland Oregon.  It illustrates a dramatic change since 1900 to today, from 14° East to 22° East (currently), a full 8° difference over time.

Bear in mind, magnetic declination has a greater, more exaggerated variance and effect closer to the equator.

So what does it mean for the Ham rotating a large beam?  Everything.  Everything should be based on current data, specific for their location.  It matters.

For the correct current magnetic declination information on your location, go to:   https://www.magnetic-declination.com

Many of the online references, even those at the USGS website are incorrect.  Printed maps, topographic maps, are often incorrect.

Accordingly, you’ll need to orient your Azimuth map, and your antenna orientation!  In my case, 12° 52′ East in Boise… Not 15° East as shown on USGS references.

It may not seem as important in HF field operations, given many field operators utilize wire antennas and therefore antennas orientation is less impacted by precise magnetic declination.  But you need to understand these changes, in declination and magnetic north are, in some way, connected to the Sun and its influence on radio propagation, and the earth’s geomagnetic fields.

As an example… In WW2, the US Navy torpedoes often failed to detonate properly due to their magnetic proximity fuse detonators.  The problem:  They were not properly calibrated to their respective lat/long declinations.  A simple oversight, or a misunderstanding with profound implications. Its costs were incalculable and directly affected the war effort.

Per my previous post, “The World is flat!  Just ask any Ham!” I’d encourage you to visit NS6T.net, print out a correct azimuth map for your location, and get your current magnetic declination, and adjust accordingly.

Well then, there ya go… Shoot straight, Good DX, and 72!

VA3EKR’s Experiments in Capturing Clean Audio in the Field

Many thanks to Scott (VA3EKR) who shares the following guest post which was originally posted on his blog:

Mar. 29, 2025, Troubleshooting Audio Capture with Voice Recorder

by Scott (VA3EKR)

When I activate a park for POTA, I always use HAMRS, running on a tablet as I get better battery life than a laptop, and I confess I still like the confirmation from QRZ that you have the correct contact, or that it at least matches the state you think it is. Still, sometimes I do not have internet connectivity, and additionally, I often neglect to put in the proper RST of the QSO in the fields (POTA doesn’t actually require it), as the tablet is not terrific about hopping between fields.

A nice solution to this is audio capture, where I can fix a broken call sign, fix the RST before submitting to QRZ/LOTW. I am too self-conscious to video myself, so I use an audio recorder. It is pictured below. It was only about CAD $100, and has a nice line-in and a line-out so that I can record while I listen.

Next to the recorder is a toroid I had as extra when I made a transformer last summer, and a relatively long audio cable that I coiled as many times as I could around the toroid.

This is an example of the audio quality before troubleshooting the problem. Just the first few seconds demonstrate the issue.

Audio Player

The received audio is reasonable, and it is when I am sending that the problem shows itself. It was unclear what the problem was, perhaps one of:

  1. Bad audio levels, either the gain on the recorder, or the monitor level of the KX2.
  2. Stray RF being coming back from the antenna on transmission
  3. The audio input cable acting as an antenna picking up transmission

I did not think it was bad audio levels, as I had done some playing-about, though not in a terribly rigorous fashion. The stray RF was my largest suspicion, as I had only started noticing the problem when I started using a Ham Stick in my car during the winter months. Inside the car, there are a series of LEDs on the transmission shifter that indicate what gear the car presently is engaged. I noticed that when I transmit, the “drive” LED flickered a LOT, and this worried me. I had not bothered to ground the HamStick to the car chassis, but did run a 17-foot counterpoise that I clipped to the antenna shield, and I hoped this would be sufficient. As corroboration, I have been able to hit France, Spain, Norway, Oregon and Idaho with the setup.

After a very chilly and rainy day at the horse barn, I was tempted to do an activation, but I decided to stay in the warm house and do some experimentation. I set up in the living room with my AlexLoop that I got in Dayton last year. This gave me the opportunity to try another configuration, and see if the audio was the same as when using the Ham Stick in the car. Indeed it was.

I tuned the loop for maximum noise on 20m, and tuned with the internal ATU of the KX2. I found a POTA activation in North Carolina, and he gave me a 599 with 5 W! I love getting surprising performance with obviously bad operating conditions, like from the interior of a brick house! And the antenna was oriented for east-west, not south! But the audio was still terrible when transmitting.

I spent some more time adjusting the monitor level, and recorder gain. Still nothing sounded good.

I next wanted to see if perhaps the common-mode current was the issue, so I used a LDG 1:1 UnUn, shown below. I was really hoping it was not this, since when you add the BNC connectors and the additional cable, the added size is about the size of a KH1!

After putting the transformer in line with the antenna, the audio was not appreciably different.

The last experiment, corresponding with the last theory, was to put in an audio cable that had better shielding from HF.

This seemed to really do the trick! Here’s the resulting audio with a QSO to North Carolina from inside my living room. There is an initial try at the beginning, and then another successful QSO at the 1:17 mark.

I hope that if anyone else encounters similar issues recording from their radio, that this might prove useful.

QSO Party, POTA, and a Touch of Winter: Bob and Alanna’s Radio Adventures on the Outer Banks

Radio Adventures on the Outer Banks of North Carolina

by Bob K4RLC & Alanna K4AAC     

February 2025

My YL Alanna K4AAC had been advocating for a trip to the Outer Banks of North Carolina for some time. She had never been there to see its incredible natural beauty, and I had not been in decades. In planning, we needed to go in the off-season, especially when it was a bit chilly, as she is a “bug magnet” and that can ruin her vacation. Not being totally unselfish, I wanted our visit to coincide with a radio event.

We first tried for Winter Field Day at the end of January, but Eastern North Carolina was socked in with five to seven inches of snow in places where it never snows. We rescheduled the trip for a month later at the end of February, to coincide with the North Carolina QSO Party. Just so happens, Eastern North Carolina got another freak snowstorm of several inches, but we only had to put the trip off one day. Even then, parts of the roads going down east were still covered in snow and ice.

The drive is only a bit over 3 hours straight down US Highway 64 to the Outer Banks, where it dead ends in a T intersection with infamous North Carolina Hwy 12. Locals call the intersection “Whalebone Junction.” Going either north or south of this intersection, within a few miles one can explore lots of really beautiful natural areas, including six (6) POTA sites! Eight miles south of the intersection is the Oregon Inlet Campground on Bodie Island, part of the Cape Hatteras National Seashore (US-0682), where we camped. That time of year, the campground was really deserted with only a few other campers including a few brave souls tent camping. It is a flat area campground that backs up to huge dunes, separating you from some of the most beautiful but austere beaches on the Atlantic coast. A word of caution though, there are no trees or light poles to secure a mast for an antenna.

We took our Winnebago Solis again. The Solis is a wonderful camper van on a Dodge ProMaster chassis that sleeps three, has a propane powered furnace and two burner stove, and a refrigerator that can be powered either by propane or by the 140 W solar panels on top of the van, loading up two 100 amp hour AGM batteries.  You can boondock for days, or enjoy the luxury of “shore power.”

As the North Carolina QSO Party was Sunday, we wanted to explore the islands Saturday. About 20 miles north of the campground is the incredible Wright Brothers National Memorial, commemorating the first flight ever, and also POTA site: US-0797.  This is part of the National Park Service, on 428 acres with an interactive Visitor Center whose exhibits include a full-scale reproduction of the Wright Brothers 1903 flyer. We particularly enjoyed climbing to the Wright Brothers Monument standing 60-feet tall atop Kill Devil’s Hill, a 90 foot high grass-stabilized sand dune. The original runway is there with First Flight Boulder and Markers charting the short distances of the first four flights. Incredibly, a few yards over and parallel is an actual 3000 foot First Flight Airstrip where pilots from all over the world fly in to celebrate their flying heritage. I decided to take the KH1 up to the top of the Monument, a steep but accessible walk for almost anyone. The day was clear and sunny; the white granite monument was gleaming against the Carolina blue sky.

It was a beautiful day to set up on the wall around the monument. Unfortunately, the temperatures were in the 40’s, and I didn’t realize there would be a 20-25 knot wind blowing. The beautiful thing about the KH1 is that it is so easy to deploy. Some have complained about the stock key in cold weather, but for me the problems are not the key but old, cold fingers. To help a little bit, I set up the AX1 on a small camera tripod and threw one 13 ft radial over the wall into the field. This modification worked really well when I operated at a Greek Navy lighthouse in the Aegean Sea. For some reason, the KH1 was fussy that day, and would not hold a tune consistently on 20 CW. Nevertheless, I pounded away until I got the minimum number of contacts about the same time my fingers just wouldn’t work anymore.

Alanna, with freezing extremities after fully exploring the monument and taking pictures of me operating, hiked off to explore a bronze sculpture garden which recreates the scene of the historic 1903 flight. This included a sandy plot with a life-size bronze replica of the original Wright Brothers airplane (being piloted by Orville laying on his stomach), along with bronze sculptures depicting the guys from the Hatteras Life Saving Station who were there to support Orville and Wilbur, help them launch their flyer, and capture a photo of the First Flight. The memorial was gifted by the State of North Carolina to the NPS,  and dedicated at the Centennial of the First Flight in 2003, by then Governor Mike Easley. Alanna and I were both really cold and tired after hiking in the chilly weather at the park, so we sought out one of the few open seafood restaurants there and were treated to an incredibly tasty buffet.

Weather Sunday morning was milder so with a strong cup of coffee from the French press coffee maker our daughter gave us, I set up on the picnic table with my trusty old ICOM IC – 706MkIIG at about 60 watts on 20 CW. I do have a trailer hitch mount for the Solis that can hold a 30 foot fiberglass mast, but I knew we were going to be traveling that day. So I set up my trustee default of a 17 foot whip on a 4 x 7′ piece of aluminum screen wire from Lowe’s. With one CQ, the calls started coming in, with the first one being from HA9RE in Hungary.

Christian’s 100th POTA Activation at Tsatelet Nature Reserve

My 100th POTA Activation at the Place It All Began

by Christian (IX1CKN)

Mathematics is a finite science. So, for a while, I knew that my 100th POTA activation was coming. The only thing left was to decide how to organize and experience it. Initially, I considered activating a new reference (paradoxically, I still have quite a few left to do in Valle d’Aosta). However, with snow covering everything above 1500–1600 meters, I reconsidered my plan.

In the end, I asked myself—what’s the beauty of this program? It’s in the experiences it awards. From discovering forgotten places or ones you’ve never visited to the strong sense of community among participants—friends who, even on your 20th activation at the same park, are still happy to log you. So, I thought it was only natural that this activation would be from IT-0120, the Tsatelet Nature Reserve. It’s the closest to home, the place where I’ve learned the most about field operating, and also where it all began for me (back in November 2022).

I started early in the morning of Sunday 9th March 2025, following my wife’s advice (she knows me too well): “Have breakfast at McDonald’s”—because while she may not like their burgers, those croissants and coffee do make sense.

It was just after sunrise, but not too cold—3°C in the air suggested that once I reached the reserve, I wouldn’t be freezing. And so it was when I arrived at about 800 meters, on the promontory between Aosta and Saint-Christophe.

I decided to take things slow and fully appreciate the memories that these two years of POTA have given me.

I had my G90, a 15Ah battery (thankfully, the hike wasn’t endless, and my back thanked me), and a 40m half-wave end-fed antenna (by Ricky IU1PZC). I didn’t bring my vertical—I wanted nearby Italian operators to have a better chance of making contact.

I started on 7 MHz at 08:32 local time. The band was responsive, and by the time I switched to 20m, I already had over 30 QSOs in the log. 20 meters weren’t performing as usual, likely due to the K-index at 5, which signaled less-than-ideal propagation. It came in waves, though—not entirely bad. In one of these, I logged Don G0RQL. As strong as ever, he told me, “I wish I had logged you all 100 times, but I was there for quite a few of them”.

He was right—if I had to guess, I’d say at least 30–40 times. Funny enough, I saw his QTH in Devonshire on vacation before I even joined the POTA family. The band continued its ups and downs, but I logged several park-to-park contacts, including an eclectic group from IT-0135 (I ended up logging three of them). Shoutout to Austrian colleagues OE3BIY, OE4JHW, and OE4ENU, who were even live on YouTube.

I also took the time to enjoy the scenery and the moment—especially when a lively group of Scouts arrived. After all, this is their place, and I’m the guest. Tsatelet is known as Quota BP, named after Sir Baden-Powell, the founder of Scouting, who is honored with a plaque in the reserve.

Back on 40m, I managed a somewhat challenging QSO with Dario IZ3QFG (sadly, no luck with Andrea IW0HK today). But something special happened—I heard a female voice calling me, and I almost couldn’t believe my ears: Helga IN3FHE, had picked up the microphone again. She said, “I know you’re having fun, but this morning, have the most fun, okay?” Mission accomplished! You can’t hear hugs on the radio, but I swear today’s felt real.

Back on 20m, the conditions remained unpredictable, but the QSO flow continued. I logged several French stations (mainly from the north), two new YL hunters (one in Wales, the other in England), and a mobile operator in Richmond Park, London—we had a laugh about how it’s Mick Jagger’s neighborhood (another “Sir”…).

A couple of local IX1 stations called in—there aren’t many of us with this prefix, but we do exist, and sometimes there’s more than just two of us in HF at the same time! Looking at my log pages, I suspected this might be one of my most productive activations ever—but in that moment, the numbers didn’t matter. I kept going because the thrill was in communicating, answering, and finding other people out in the middle of nowhere with just a radio and an antenna, sometimes barely holding together.

Spanish stations stood out—some of them are regulars in my log (EA2DT, EA5W, EA2CPG, EA6FM, and many others), and they always have a strong presence. Their enthusiasm is infectious, and they always deserve the “abrazo” and “suerte” that close every QSO with them. 15m wasn’t too promising, but on 10m, some stations from the South America contest came through. I called them, skeptical about my 15 watts, but I still logged two Brazilians, one Argentinian, and two Turkish stations. There it was—the DX!

At 12:03 local time, after 3 hours and 31 minutes, I had relived practically all the highlights of my time as an operator. It was enough—but what a fantastic activation. I packed up, hiked down, and headed home.

Then came the logbook surprise:

  • 136 QSOs
  • 21 park-to-park contacts
  • ODX: LT3E (Argentina) at 11,454 km—a new personal best from Tsatelet! (My previous record was 135 QSOs.)

If someone had asked me how I wanted my 100th activation to be, my answer wouldn’t have been far from this.

Now, onwards to the next 100! But not before saying thank you to everyone who makes this program so special.
