How I worked the #19 most wanted CW DXCC as a pedestrian mobile station

by Leo (DL2COM)

A couple of months ago, I started using the app HamAlert to keep track of interesting DXpeditions and rare call signs just to check if I would be able to copy their signal on my home-made WebSDR at a location outside of the city. This helped me a great deal in understanding propagation and pile-up dynamics as I began to develop a strong interest for expedition-like operating from exotic regions.

One of the stations I had tracked for a while is Monk Iakovos Kutlumusian SV2RSG/A – the only licensed operator in Mount Athos which is currently #19 most wanted CW DXCC according to Clublog. Mount Athos is an autonomous orthodox monk republic under Greek sovereignty and located on a peninsula in the North-East of Greece (locator KN20CG). More info on Mount Athos can be found here (Wikipedia) and a trailer for an upcoming documentary here (Youtube).

The priorities of the community in Mount Athos understandably lie on their theological work. So I think it is a big commitment that Monk Iakovos (QTH: Koutloumousiou Monastery one of 20 monasteries in Mount Athos) is able to make some contacts in his free time outside his monastic duties as he writes on his QRZ page.

Very experienced DXers from Berlin once told me how they worked Mount Athos many moons ago on 80m in the middle of the night only by chance and that it is almost impossible to log this super rare DXCC.

Impossible? Hold my beer.

I had noticed that during May and June 2024 Monk Iakovos was on the air more frequently but each time only working 4-5 stations in a couple of minutes before disappearing again for days. The only two consistencies I found was that he was active on 20m CW and most of the time during local evening hours.

Whoops there he is again – Hamalert notification on the Garmin Instinct 2 watch

I took the photo above a couple of days before to inform a friend that SV2RSG/A was active again (btw the HamAlert notification feature on my watch comes in very handy).

Then on Sunday, June 16th 2024, I was sitting on the couch reading when my watch vibrated and showed his call sign again on RBN at about 20:56 UTC (22:56 local time, 23:56 DX time).

I was in absolutely no position to make a QSO as I live in a very urban neighborhood in central Berlin City and I cannot have antennas at my QTH. Also the location brings along a high degree of man-made QRM and all the tall townhouses act as blockers for any kind of RF. Far from ideal for HF operation which is the reason 100% of me operating is portable or from the car.

In addition, we had just returned from a weekend trip to the countryside and I was enjoying the fact that our kids were sound asleep. So I only took out my phone and checked if I could hear this station again online.

To my surprise, this time it wasn’t the immediate and very intense “red ocean” simplex pile-up that I had witnessed multiple times during the weeks before. Maybe it was due to the fact that a big DX contest was coming to an end or most tired OPs were just off the air already on a late Sunday evening. Who knows? Or maybe it was just plain luck…..

Should I? Or should I not? I knew that I needed to be outside if I wanted to have the slightest chance to work this station. There is also a tiny park about 200 meters from our house which would improve my situation a little due to better “sky access” and takeoff angels towards Greece. But I thought by the time I could be set up the pile-up would already be too big for my QRP signal or the station would already be gone as it was the case each time before.

Still I ran over to our utility room, ripped open my backpack and got the KX-2 pouch out. I took the transceiver, slapped the AX-1 whip on, grabbed a key and dumped the counterpoise wire in my pocket.

Don’t let the shoe situation mess up your TTQ stats (time-to-QRV)

Have you ever wanted to take out the trash and then ran into a “shoe situation” at the front door with your hands full?

With my wife’s sneakers slipped half on I staggered out on the street all while trying to secure the end of the counterpoise to one of the bottom screws on the KX-2’s case and nearly falling down the stairs. Time-to-QRV (TTQ is that an official metric? if not it should be imho) maybe 80-100 seconds….no kidding.

Outside I dialed in 14.004 and immediately heard SV2RSG/A still calling CQ at a relaxed pace and then working a station. The signal in my “street canyon” was weak but a 100% copy.

Elecraft KX-2 and AX-1 whip antenna
Elecraft KX-2 and AX-1 whip antenna got me on the air in no time (I need to set the internal clock again)

I quickly send my call sign only to get a “QRZ?” back. OMG did he really just hear my signal? Apparently my field strength was too weak on his end because he started calling CQ again.

So I sprinted towards the park (dragging along the counterpoise behind me) and I noticed that his signal was coming on stronger and stronger. After about 100 meters I stopped and again called “DL2COM”. This time I heard “DL2?” but then a very loud OP blasting his signal right on top of me.

I repeated my call another two times and couldn’t believe my ears when SV2RSG/A came back with my true full call and a 599 report. With shaking hands I somehow managed to reply R 599 TU and then we exchanged 73s. I simply couldn’t believe what had just happened.

When I walked back to the front door one of my neighbors was standing there looking somewhat irritated. He paused his phone call for a second and asked “ARE WE SAFE?”.

“Oh yes! For now, very safe!” I told him that I had just communicated with a monk in Greece in morse code (“you know the stuff they used on ships back in the day”) and that this story probably needed more context over a beer.

I then noticed that I had pulled the counterpoise wire through a pile of dog droppings with everything happening so quickly. Of course I did! How can this not happen on the streets of Berlin. A sacrifice I was happy to make for this very special contact and btw cleaned easily in under 2 minutes.

Thanks to QSL manager SV1GRM I did not have to wait long for this card

How did this work? Being on the air so quickly and the fact that 20m was on fire that night certainly helped. But then again is it also the idea to just dare and get out there operating. If you don’t cast a line there won’t be any fish…right?

You never know which exciting DX station might be just around the corner during a special band opening.

While Greece isn’t particularly hard to reach from Germany it was more the overall circumstances (very rare, short and erratic operating times of this station, usage of callsign by pirates, urban QTH, compromised antenna, simplex pile-up with QRP signal) that made this contact highly unlikely but as I now know also totally possible. Blessings to Mt. Athos and their ongoing work for the DX-community! I am very grateful that I got the chance to log them.

p.s. as of the day of publishing this article, Monk Iakovos has not been active since I worked him on June 16th (according to RBN).

W2AEW’s Trapped EFHW Antenna Tutorial: Building a Smaller, More Versatile Solution for Portable Operations

8 Comments

Many thanks to Alan (W2AEW) for the following guest post:

Trapped EFHW antenna story (it’s all Vince’s fault)

by Alan (W2AEW)

One of my favorite antennas to use for POTA activations is a 40m EFHW wire.  When properly tuned and deployed, it can be used on 40, 20, 15 and 10m without the use of a tuner (although, I really don’t mind using a tuner when I need to).  Most of my activations are on 40 and 20m, so those bands are covered easily.  It can be used successfully as a sloper, an inverted vee, or a combination of these (whatever the trees or support structures allow).  It is efficient, inexpensive to build, lightweight and effective.

There are a few downsides to this antenna.  The first is that it is approximately 68 feet (almost 21 meters) long.  That’s a lot of wire to get in the air.  Some POTA sites just don’t have that much room or support structures to effectively use this antenna.  Another downside is that it doesn’t naturally support operation on the 30m band, another favorite of mine.

A few weeks ago, I watched a video from my friend Vince VE6LK entitled: “Discover the secret ingredients to build a trapped EFHW antenna”. This piqued my interest…

The video introduces a design for a 40/30/20m trapped EFHW.  The fact that it covers the three bands I use the most, and would be shorter than my trusty full-sized 40m, and give me 30m to boot, got me excited to learn more.

Vince used a pair of traps (30m and 20m) that are offered in kit form by Tim Sherry, N7KOM.  Here is a link to kit on Etsy.

Image Source: Tim Sherry, N7KOM

These are exclusively for use at QRP power levels – perfect for my application.  I placed my order immediately after watching the video.  The build instructions are very detailed, including how to tune the traps, which is critical in getting the antenna to work.

Image source: SparkPlugGear

He also used a 49:1 UNUN from SparkPlugGear.  I’ve had one of these in my POTA kit for a while, but only used it occasionally.  This was another good reason to proceed with this antenna build.

Of course, you could also use the QRP UNUN kit from KM4CFT that I made a video about earlier this year.

I created a video that showed how to assemble and tune the traps.  Tuning can be a little tricky, and then stabilizing the turns/spacing to preserve the tuning is critical – not hard, just takes a bit of patience.

With the traps built and tuned, the next step would be to build and tune the antenna itself.

I was able to find the time this weekend to do just that, and make a video of the process.

Details of the resulting wire segment lengths are in the video.  It is important to note that if you decide to build this antenna, your wire lengths will likely vary from mine.  Several factors will effect the resulting lengths (details of the UNUN used, the trap construction, etc.).  My video goes through the process I used to build, tune and test the antenna.

“The proof is in the pudding” as they say.  It was time to actually run a POTA activation with this antenna.  The overall length of the antenna was about 43 feet (about 13.1 meters), which is about 2/3rds the length of the 40m EFHW.  This opens the possibility of using my 12 meter Spiderbeam mast (video review) as a support rather than just relying on a tree branch.

The weather here in NJ has been oppressively hot and humid with heat indexes over 100F, so I opted for a morning activation, before the heat really built up.  The intent was to get some contacts on all three bands, even though 20m probably wouldn’t be very active.

I setup at my “home” park – Washington Rock State Park, US-1635.  I decided to setup the Spiderbeam mast as the support for the new antenna:

The rig was my trusty KX2 with the BamaTech TP-III paddles:

I only had about an hour to dedicate to operating before the family activities for the day, so I figured I’d start on 40m and get most of the “ten” there first, then move on to pick up a few on 30m and 20m.

I was able to put 14 contacts in the log, under “so-so” band conditions, which at least a few on each band, several of which were park-to-park contacts.

Here’s the map of the “reach” that the new antenna had during this short activation:

Overall I am quite pleased with the antenna’s performance.  The near ideal band coverage for my typical activations, and the ease of deployment compared to the full-sized 40m EFHW make this antenna a great addition to my POTA kit.  I suspect it will get a lot of use!

Where the Heck is the POTA Babe?

7 Comments

by Teri (KO4WFP)

Okay. Y’all haven’t heard much from me lately and may be wondering, “What the heck is the POTA Babe up to?” Actually, a lot!

Earlier this year, I asked QRPer readers for suggestions as to parks to visit for a summer POTA trip to either North Carolina and/or Virginia. I appreciate all the suggestions I received. In evaluating the time I have and that I’ll be driving by myself, I have opted to visit North Carolina. I’ll be on the road for eight days mid-July camping with Daisy. I hope to activate ten to eleven parks as well as successfully complete four SOTA activations. It is a lot to bite off but then I enjoy being challenged.

I originally planned for a twelve-day trip but decided to nix the second week near the Charlotte area due to obligations at home. I am bummed at missing out on those parks. (Thank you Bob K4RLC for the recommendations in that area.) However, now I’ll have those parks to activate on a future trip.

Preparing for this trip is no slap-dash endeavor. At least not for this POTA Babe. As I mentioned in the articles of my last trip to southwest Georgia, I am tweaking my camping equipment as well as how I organize and access those items.

An item I’ve added is a fan because camping in July might be a bit toasty, even in western North Carolina. My partner Glenn W4YES came across a helpful video on the CheapRVLiving Youtube Channel discussing USB-charged devices. The Koonie 8” rechargeable fan was mentioned. As it received favorable reviews on Amazon and I can charge it using my Jackery, it is now in my arsenal for summer camping.

I also added an ultralight shelter I may use on a summit or for POTA in general. While researching summits to activate, I came across a picture on the SOTlas website and reached out to that op as to information about the tarp he was using for shade. Patrick WW4D introduced me to Mountain Laurel Designs, a company that makes ultralight shelters (tarps and tents). They aren’t inexpensive, but then I’ve learned to purchase good quality where I can. In a shelter, good quality counts.

I purchased the Trailstar. It can be used as a tent or a shelter. Before the trip, I need to seal the seams. What I didn’t realize until the other day is that I will also need to cut the guylines as well as figure out what knots to use in securing the guylines to the stakes included. Then I have to learn how to set it up using my hiking poles. The learning never ends, does it?

I couldn’t believe how light the Trailstar is having never experienced a shelter like it. It will be a welcome addition to my SOTA backpack since it weighs hardly anything.

I’ve also undertaken re-waterproofing my tent. Sierra Designs sent me instructions and information about the products they recommend which I ordered. I thought to myself “how hard could it be to re-waterproof a tent?” Those of you who have done this know it is a time-consuming process! You have to remove the old waterproofing substances before applying the new ones. The substances used for waterproofing fabric are meant to not come off easily, especially after being on there for 30 years (the age of my tent). I’ve spent more time in the bathtub scrubbing and smelling rubbing alcohol than I care to admit. However, when this process is finished, my tent and its rainfly will be clean and good to go for another eight years or so.

I am also researching how to do a SOTA activation. I’ve found quite a few helpful videos on Youtube and plan to reference them in a future article. For my pack, I am using a Six Moons Designs ultralight pack (the Flight 30 Ultra) I purchased about four years ago. As it was not being used, I’ve been employing it as my POTA pack for several months now.  Given I’ll be hiking to activate summits, I need to rethink what I’ll take in the pack since, in addition to ham gear, I’ll need emergency supplies one should take when hiking.

While preparing for this trip, I’ve had a new addition to my shack that is sharing my focus as of late. Nearly two years ago, I ordered a Frattini Magnetic Evolution bug. I didn’t hear anything further for the longest time and figured it wouldn’t ever arrive. Then, about four weeks ago, Alberto Frattini sent me an email the key was ready and, oh by the way, was I still interested in it? You bet I was! “The Frattini” (as I call it) is now in my shack and I am resuming my pursuit of the Straight Key Century Club’s (SKCC) Triple Key Award. (When I’m not scrubbing the tent, mind you.) My fist is a work in progress but what a great challenge!

my Frattini Magnetic Evolution bug
Hummer on the Frattini plate – a nice touch given my POTA Babe logo also has a hummingbird on it

My goal is to run at three speeds eventually – 16, 20, and 25 wpm. Right now I am concentrating on 16 wpm as that is a good speed for SKCC QSOs. At that speed, I am more relaxed and the more relaxed I am, the better I can focus on making my characters correctly with good spacing. My goal with the Frattini is that the dits and dahs be proportional and timed well enough it doesn’t sound like I am using a bug. With continued practice off and on the air, I will eventually get there.

One thing I’ve found that helps is having either Word List Trainer up and running or my Morserino in the shack. Just like a choir conductor will play a note on a pitch pipe for a choir, I’ll play the letter “o” at 16 wpm to get that dah cadence in my head before I get on the air. Eventually, I’ll fall into that rhythm naturally at that speed but in the meantime, I find that trick extremely helpful with my timing of the dahs.

If you’d like to hear my bug fist (a work in progress, mind you), click on the video link here to access it on Youtube.  Also, if you’d like to follow my progress on earning bug QSOs for the Triple Key award, check out the goals section on my QRZ page.

Well, there you have it – my ham radio related doings since my southwest Georgia POTA trip. For those interested in hunting me while I’m in North Carolina, I will not release my itinerary in advance for safety reasons. However, Glenn or I will schedule my activations each morning so keep an eye out on the POTA and SOTA Watch pages beginning July 14 if you are keen to work me and support the trip.

I am a little nervous about the trip.  I’m going to be out of my comfort zone and sure to make mistakes. However, this is how we learn – making mistakes. This is a part of ham radio and such a trip – the unknown! Who knows what I’ll learn and discover along the way. I hope to work many of you that week and look forward to sharing with you those adventures on QRPer.com after my return. But before I leave next Sunday, I plan a POTA activation Monday, July 8 to get my head back in the game. What park will I pick? Stay tuned…

Friedrichshafen: POTA Across Borders

by Christian (IX1CKN)

The Friedricshafen fair is one of the most interesting events for its social aspects, where you can finally put a face to colleagues whose voices you’ve only ever heard. Among the various OM (radio amateurs) I met this year was Gabriele IT9RGY, a flagbearer of the Italian Contest Club. When he recognized Andrea IW0HK and me, he said, referring to our respective SOTA/POTA activities: “You two are the real deal.”

I found that to be a very powerful statement, and I am grateful to him for it. Personally, I try to document each outing to capture the sensations it gave me, but also in the hope of inspiring someone. Andrea is more succinct than I am (if we were all the same, the world would be boring), but his spirit is identical. Parks on the Air (POTA) is a state of mind. It was no coincidence that, being in Germany for the Hamradio Messe, we had planned a series of activations.

Our schedule was tight and ambitious, and just completing it was a source of happiness, but there’s more to tell. In Germany, dinner time isn’t synchronized with Roman schedules. So, on Friday evening, after leaving the restaurant (for dinner with the Summits On The Air group) at 20:23, I looked at Hotel-Kilo and said, “If I go to bed now, I’ll digest in a week; let’s go activate a reserve!”

The easiest option in the area (after a disastrous experience last year in DE-0156, the park in the town center hosting the fair) was DE-0766, the Seewald Landscape Reserve. It’s near the FRN airport (and thus not far from the fairgrounds), in a fully bucolic setting. A narrow road cuts through meadows, with footpaths and bike paths leading into a wooded area.

We parked the car in one of these spots. It took only a moment to set up the vertical antenna in the field, but the presence of a swarm of mosquitoes as big as F-18 Hornets advised us to operate from inside the car to save our skin (literally).

Andrea turned on the KX-3 (10 watts would be our fixed power for this trip), and the 14 MHz calls began. Right away, a very strong IZ3QFG Dario (just 380 km from us) answered, highlighting an unusually short skip.

We logged 20 QSOs in 30 minutes… Many were from Italy (Spartaco from Grosseto at full scale, Mauro I1JQJ always active, and Beppe I1WKN a constant), with two “park to park” contacts. A classic for many OMs in the area, but also a great mood booster and a tasty appetizer for the next day… Continue reading Friedrichshafen: Christian and Andrea’s Multi-Country POTA Rove →

QRP SOTA: Lee pairs the KH1 and MPAS 2.0 to activate High Willhayes (G/DC-001)

SOTA CW Activation on High Willhayes Dartmoor

by Lee (M0VKR)

It was an overcast and breezy morning when wife Joanne and myself Lee, M0VKR set out on our latest SOTA (Summits on the Air) activation adventure. Our destination was High Willhays, the highest point in Devon UK – SOTA G/DC001, Dartmoor is well known for its rugged beauty and challenging terrain.

We parked the car a short distance up the road from the army camp, slung our packs over our backs and set off. The gravel tracks leading to the summit stretched out before us and took a winding path through the moorland.

A few sheep and cattle grazed in the rough grass as we made our way upwards on the gentle slope. It was a breezy morning and we had had rain a short while earlier. Despite the weather our spirits were high, and we were eager to reach the top and get on the air with the Elecraft KH1.

In my pack was my now trusty Elecraft KH1 and an MPAS 2.0 vertical antenna, with the KX3 as backup, a reliable setup for such expeditions. I’m pretty sure I could halve the weight in my pack, but as it’s not a huge walk to the summit I don’t mind ferrying the extra gear to the top. The weather, though overcast, was adding a touch of drama to the landscape, and the breeze kept us cool as we trekked upward.

Joanne, ever the supportive partner, helped carry some of the cooking equipment and victuals and she kept the mood light with her cheerful conversation.

After a brisk hike, we reached the summit of High Willhays. The view, even under the Grey sky, was breathtaking. Rolling green hills and expansive moorland stretched out as far as the eye could see.

I set about preparing the station, using the MPAS 2.0 vertical antenna, which is quick to deploy and ideal for the variable conditions we faced. Despite the less-than-ideal propagation conditions, I was determined to make the activation a success.

Although the MPAS in vertical form isn’t very efficient on 40, I prefer to take advantage of the quick setup that it offers, one of these days I will look at adding a top section to make 40 more efficient, perhaps as a sloping inverted L or something similar, more reading of the manual required!

With everything set up, I made the first call on the 40m band. My Friend Matt MW0KAX answered, he was essentially line of sight from Wales, so his signal was strong. That was the first and last contact on 40m. I changed to 20 meters, where the MPAS was more efficient for the little KH1 and it was able to breathe a bit easier. The tuner in the KH1 is nothing short of amazing, and quite happily tuned 40 meters in a few seconds.

The static crackled, and for a moment, there was silence. Then, a faint reply came through. The thrill of making that first contact was palpable. It still amazes me every time I make those first few contacts that QRP does work, even with a compromised antenna system. Despite the challenging conditions, My limited skill, Plenty of luck and the reliability of the equipment began to shine. All the equipment I was using was off the shelf, I hadn’t made a single thing myself, maybe one day.

One by one, contacts started to come in. Each short QSO contact was a small victory, a testament to perseverance and the joy of ham radio. It is necessary to persevere as a newer CW operator and use QRP power levels and poor propagation conditions. It’s non-negotiable after driving for 2 hours, and a 4km hike that we go home empty handed. I logged each contact meticulously, my excitement growing with every successful connection. Joanne watched on slightly bemused but very supportive of the hobby, sharing in the triumphs that each contact brings and providing much-needed encouragement.

By the end of the activation, We had made several QSOs. While the propagation conditions had been far from ideal, the activation was undeniably a success. We had achieved what we set out to do: connect with fellow hams across the airwaves from the summit of High Willhays for a SOTA activation.

As we packed up our gear, the breeze picked up, and the clouds began to clear slightly, offering a glimpse of blue sky. The trek back down was filled with reflections on the day’s achievements and plans for future activations. We both felt a deep sense of accomplishment. We had braved the elements, navigated the challenging RF conditions, and emerged victorious.

This activation, like many before it, was a reminder of the joys of ham radio, CW and QRP operation and the adventure it can bring. For me and my wife Joanne, High Willhays would always hold a special place in our memories, not just for its height, but for the heights that we reached together on the airwaves.

Take care and Speak soon, 72,

WN5C: Notes from a homebrew POTA adventure

Many thanks to Sam (WN5C) who shares the following guest post:

Notes from a homebrew POTA adventure

Sam (WN5C)

I recently wrote about the homebrew transceiver I built to operate on a month-long trip through the American Southwest. Upon arriving back in Oklahoma here’s the final outcome: 27 days, 40 parks, and 669 QSOs. I honestly can’t believe that the rig went the distance, or that I made so many contacts on 2 watts or less!

The priority of this trip wasn’t radio, though. I’m an archaeologist and I’m starting a new research project that marries my historical interests with my love of two-way communication. In short, I’m studying the effects of how communication technology aided the American colonization and transformation of the western United States around the turn of the twentieth century. This means I walked and mapped single-wire telephone lines strung up in pine trees in northern New Mexico (used to connect fire lookouts with Forest Service ranger stations), a fascinating story of dramatic changes in land management. I also visited heliograph (sun-mirror signaling) stations established in southeastern Arizona by the U.S. Army Signal Corps in 1886 to assist in apprehending Geronimo.

Working Fort Bowie NHS (US-0815) in Arizona. The peak in the distance, Helen’s Dome, had a heliograph station on top. From the fort telegraph lines would have connected remote operations to the rest of the Army’s 1880s communication network. Next time I’m climbing up on top!

I look forward to relocating and studying the artifacts from more of these heliograph sites (mostly on remote peaks) to reconstruct this communication network and understand the lives of both the soldiers and the Apache, and how this novel surveillance system altered the battlefield. Based on the artifacts I’ve seen so far there are many cans of Army-issued proto-Spam and beer bottles surrounding the signaling station where American Morse Code would have been sent and received via flashes of sunlight. The original Field Day?

But back to radio. I covered a lot of ground and activated parks in Oklahoma, Texas, New Mexico, Arizona, Utah, Colorado, and Kansas.

The POTA sites that I activated (click image to enlarge).

At some locations I was camping so I was able to do multiple long activations and work the lower bands well into the evening. These were some of my favorite moments of the trip, being the only spot on the POTA app and leisurely working with no time or weather-based worries. It also gave me a chance to hear callsigns I was unfamiliar with, essentially exploring a new area of the country.

Working closer states after hours on 30 and 40 meters at Colorado NM (US-0918).

For other times, due to time constraints or weather (thunderstorms or that it was unbearably hot), I got my 10 contacts and moved on. Sometimes I packed the equipment for a long hike, often carried it from the car to a picnic table, and a few times deployed my antenna and operated from my vehicle.

Not every activation was a grand adventure. Sometimes, like here at Rocky Mountain Arsenal NWR (US-0226) in Colorado, I worked from the passenger seat in the car.

Every activation was memorable in its own way. I worked folks from 44 states, five Canadian provinces, and an unforgettable contact from Italy.

A map of the contacts I made (not including those in northern British Columbia, Alaska, and Italy).

The radio held up surprisingly well. Aside from it looking like a Dalí painting as the 3D printed box continued to deform in the heat, and some hot glue remelting, the electronic components worked as they should. I look forward to printing a stronger case and making some upgrades going into the fall. I do now have a real respect for the engineering that goes into designing field radios, especially those that are thrown into a pack!

Setting up a portable shack on Vail Pass in the White River NF in Colorado (US-4410). This was near the end of the trip, the plastic case was looking pretty bad.

After I began feeling less anxious about the homebrew radio (it kept turning on!) I could start focusing on the trip itself: an amazing POTA adventure with an often-uncooperative sun. Here’s a few themes I noted. Continue reading WN5C: Notes from a homebrew POTA adventure →

Coffee, Cobblestones and Contacts – Portable in Portugal

by Scott Schillereff, (VO1DR), St. John’s, NL, Canada

On a recent trip throughout Portugal (May 29 – June 12), I operated /P QRP CW at five locations, with varying success.  Here are some details and pictures that you might find interesting.

Portugal and /P sites

Figure 1 shows a map of Portugal and the five locations where I operated.  On this trip, we were on the move a lot, so radio was tucked in here and there when I found some free time.

I was packing the following gear in a small compartmented zip bag:

  • ATS-V5 CW transceiver for 15, 12, and 10 m (small-run kit from Steve Weber, KD1JV; fits into lid-less Altoids tin).  My max P(out) was 1.7 W on 15 m rising to 2.3 W on 10 m.
  • Homebrew whip antenna system.  2.54 m telescoping whip on top of a 2 m camera monopod; raised radial (coiled up to preset lengths to resonate on each band); no ATU; directly wired via 5 m of RG174 coax to choke at rig.
  • Homebrew common mode choke – RG174 coax threaded through five FT37-43 toroids and coiled around a larger unknown ferrite core (scavenged from TV).
  • Homebrew resistive SWR bridge – common design to null out an LED at low SWR; max tuning SWR 2:1; switchable in and out of Tx circuit; direct BNC connector to rig
  • 30,000 mA-hr Lithium-ion battery– car jump-starter; lightweight (284 g); 15V and 5V no-load outputs; 15V output through voltage controller to rig.  One charge did entire trip.
  • Homebrew Voltage Controller – simple design based on LM317T regulator and small V-A display (see article in SPRAT #195, p.24).  Vin max 40V; Vout 1.2-37V; Iout up to 1.5A.
  • Homebrew single paddle key, made with popsicle stick inside a plastic screw-top vial.

I chose a whip- versus a wire-based antenna system because I anticipated setups on hotel balconies, beaches or in city parks, not “off in the woods”.  Wire antennas are certainly more portable and could be taken in carry-on without worry, but might be more noticeable during setups in city parks.  Wire antennas are also not much good on beaches or balconies (without distant anchor points).  I wanted to be less conspicuous, and didn’t need to worry about weight.

Air travel with radio gear

I put all my QRP gear and antenna in my checked bag and had no trouble anywhere.  I added a note in English and Portuguese stating that this was amateur radio gear for hobby use, and included a copy of my Canadian licence. I probably could have taken the works in carry-on, but I was a bit uncertain about the metal monopod and whip (might be perceived as a weapon) so I just checked it all.

1. Lisbon Old Town

Due to a *two-day* travel disruption on the way to Portugal (thanks to Air Canada at Toronto Pearson airport; another story), we only had one night in Lisbon. Our hotel was a four-storey concrete and steel building in a narrow street. Our 3rd storey room had two little balconies about 3 m apart, with metal rails. To test the waters, I mounted the monopod and whip on one balcony and tied off the radial to the other balcony. The antenna impedance match was fine but, either due to band conditions, night time, or metal in the buildings, all three bands (15-10 m) were dead. Not a single signal; not even the ghoulish drone of digital signals; a total bust. Not a great start, but things improved later – read on!

2. Faro (Algarve Region)

We travelled by wonderful inter-city Portuguese train to Faro in the Algarve.  Faro is a hub city in this sun-drenched and slow-moving southern region of Portugal; a region where everyone seems to be in second gear, and quite content there. Being a coastal city, I had hopes of good propagation.  Our schedule meant I could only play radio at our hotel late one afternoon. I set up in a quiet corner of a concrete-walled, 2nd storey courtyard with an open roof.  The top of the whip extended ~1 m above the concrete wall, but the radial was deployed entirely within the courtyard.  An improvement on the air – I could hear a number of stations, mainly on 15 m, and worked LY2NK (Lithuania, 3,119 km).  I was amazed at what 1.7 W and a whip antenna with a single raised radial could do!

3. Porto and Foz do Duoro (“mouth of the Duoro”)

We travelled on a delightful high-speed train (complete with coffee and snacks trolley down the aisle!) up to Porto in the north of Portugal.  Porto has a much different vibe than the Algarve.  A more working-class, energetic, commercial feel, and steeped in the wine- and port-making industry along the picturesque Duoro River. The Duoro Valley is a huge viticulture region and, yes, they still stomp grapes with bare feet on harvest day (don’t worry – in the making of port, fortification with 60% alcohol (aguardente) abruptly stops sugar fermentation and kills every living microbe in the batch!).

One afternoon, we took a clattering electric tram from downtown Porto west to Foz do Duoro, a seaport town 6 km away where the Duoro R. empties into the Atlantic.  After an espresso in an outdoor café, I set up the radio in a city park adjacent to the ocean – monopod lashed to a park bench and a radial tied off to a palm tree.  Figure 5 shows my park bench set up with a sea wall and Atlantic in the distance.  In QRP radio, as in real estate, “localização, localização, localização”!  Conditions were great here and I worked these stations on 15 m:  TM56JO (France; 1,087 km); HA0DD (Hungary; 2,476 km); OU5U (Denmark; 2,146 km); LY2PX (Lithuania, 2,903 km); and 9A2N (Croatia, 2,119 km).  Very exciting! And, again, passers-by  took no notice.

Clockwise from L to R: paddle key in clear plastic vial; blue floss container with volume control for ear buds; ATS-V5 rig (green cover) in bottom of Altoids tin; oltage controller in bright blue Altoids tin; Li-ion battery pack (black rectangle); common mode choke (red sleeve); resistive SWR bridge (silver top with LED). Zippered back for this gear is immediately to right. The whip collapses to about 14 in and fits inside the camera monopod for transport.

4. Madeira

Air travel is fairly cheap within Portugal, so we detoured to Madeira, an autonomous Portuguese island in the Atlantic ocean ~1,000 km southwest of Lisbon.  The main city (Funchal) is about even with Casablanca on the Moroccan coast.  Madeira is a very rugged volcanic island with its highest point (Pico Ruivo) 1,862 m (6,109 ft) above sea level.  We were based in Funchal and toured around to see the sweeping vistas, mountain-scapes, and steep coastal cliffs.

Experimenting during Field Day 2024

6 Comments

by Vince (VE6LK)

Field Day 2024 started out with the best of plans to be spent with the best of friends and ended up totally different – and, unexpectedly, I had a hoot! With my carefully made plan behind me, my new last-minute plan was to run solo for Field Day in the backcountry of Kananaskis Country and bring along my new-to-me Nikon D3400 and lenses and rekindle my interest in (D)SLR photography at the same time as doing some experimentation with radio gear.

I grew up in a home with a scratch-built enlarger and a darkroom, so a love of taking pictures has been with me for a long time. My Father taught me patience to get the shot as he would set up a 120 format bellows camera on an air-triggered remote release to get closeups of chipmunks while we were camping, a process that took hours and yielded excellent results. My Brother, AG7GM, has attempted to instill within me the basics of composition, rule of threes and such and his wonderful skill in editing both stills and live video. While I have plenty of patience, with composition I think I’m fair to middling at best.

Thus photography has always been on my mind.

With a recent sale of a few ham radio related items, I had fun money, so just for fun I started looking [on Thursday before I activated] at used DSLRs and was shocked at how much camera I can get for such a relatively low cost compared to new. I had said once, 25 years ago when I divested out my 35mm kit, that when I could get a DSLR with a 25 to 300mm lens for <$500 I’d jump in… and finally that day is here, even if it means carrying two lenses. Of course, I started looking on the day before Field Day for deals – and scored them too! 🙂 Around these parts, good quality pre-owned consumer grade DSLRs are easily available. I purchased this as much for still photography as for ability in shooting high-quality video for my YouTube channel.

These peaks form part of the border between Alberta and British Columbia to the west

For me, Field Day has always been about the experimentation rather than chasing points. Trying new things. Changing up from the normal way I operate in the field. Comparing, analyzing and making notes as I go.

For example, and as a tribute to Chip Margelli K7JA (SK) after corresponding with his brother David, last year I attempted to wet a piece of string and see if the KX3’s tuner would match it and radiate a signal. Chip was known for many things, among them his proficiency in CW as he demonstrated on The Tonight Show with Jay Leno in 2005. David told me that he and Chip would do crazy and fun experiments like loading up clotheslines and wet string to experiment .. and it fostered a new direction I could take each FD and on some days between. The string experiment was a failure last year but I haven’t given up yet!

This year, I wanted to work with a few different antennas and a Charmast 100W battery pack from Amazon along with a USB-C PD 12v power cable for my KX3 [note: Amazon affiliate links!].

I wanted to know, in no uncertain terms, that the Charmast would or wouldn’t be as quiet as my trusty Talentcell LiFePO4 pack. The Charmast is also used in my field soldering kit with a Pinecil as it delivers USB-C PD. What better way to test this out than to head as far away from noise sources as possible, see the Canadian Rockies in their early summer glory with snow on the peaks, rivers running high (and cold) and the sun in the sky? Just for grins I would ensure that I was in POTA entities while doing Field Day.

M0VKR’s Lewesdon Hill SOTA activation with the Elecraft KH1

3 Comments

Many thanks to Lee (M0VKR) who shares the following field report and video:

Activating Lewesdon Hill with the Elecraft KH1

by Lee (M0VKR)

After taking a day off from work my wife Joanne and I pondered about what we could do. “Shall we go over to Dorset to that hill you have spoken about and take your new radio?” There is no need to ask me twice to get outside and activate so we were quickly packed.

The KH1 came as the Edgewood package, so everything is contained in its own pack, ready for moments just like this. I grabbed it off the shelf in the shack, along with a KX3 as backup.

Within 10 minutes we had our labradors Toby and Konnie in the car and set off on a new CW ham radio adventure to activate Lewesdon Hill in Dorset for a SOTA activation. It was mid-morning by this point and things looked promising for a perfect day of outdoor radio operation.

With my Elecraft KH1 and KX3 as a backup snugly packed, along with my trusty home brew antennas, we embarked on the journey. The drive was scenic, with the rolling hills of the Dorset countryside providing a beautiful backdrop, Traffic was light too – Perfect.

After 45 minutes or so we arrived at the base of Lewesdon Hill. I took a moment to appreciate the tranquility of the area, breathing in the fresh air. The only downside was no nearby carpark, so we parked the car in a layby making sure it wasn’t going to be in the way of any farm traffic.

Finding the right spot to set up was the first small challenge.

Lewesdon Hill is only 279 meters (915 feet) to the summit, not exactly a mountain but it is the highest point in Dorset. We set off up the concrete driveway to a local farm, then turned right through a gateway and began ascending. The ascent is marked as a footpath and is pretty much through woodland until you get to the summit. It is a relatively steep climb, and we stopped every so often to take in the expanding view of the countryside through the trees.

Joanne had completed a 10K run a few days before so was happy to stretch her legs.

We arrived at the summit in good time. I needed a location with good elevation and a clear view to maximize my reach.

After a brief walk 1KM’ish, Joanne found the perfect spot—a clearing with a panoramic view of the surrounding area and a fallen tree which made the perfect workstation. I could already feel the anticipation building as I began unpacking my gear.

Setting up the antenna is always a mix of art and science, but mostly just plain luck. Today, I was using my favourite home brew random wire, which had served me well in previous activations. I found a stone to act as a weight and tossed the wire into a tree on the first shot and with a few quick adjustments, it was up and ready. Next came the radios.

The Elecraft KH1 and KX3 are compact yet powerful, ideal for portable operations like this. Because the KH1 had been configured already at home and previous activations, I hit the tune button. It tuned the random wire within a second or so and I double checked the keyer speed and set it to 16 WPM. Luckily, there was good phone service, so I sent out a spot on the SOTA website and I was ready to start.

The band conditions were not exactly favourable, however the clear blue skies hinted at a good run. I powered up the KH1 and began calling CQ. A station in Northern Ireland came back instantly and exploded out of the speaker, at a lovely cadence. One by one, contacts started rolling in. Each successful connection was a small victory, a testament to the power of CW communication and the effectiveness of my setup and of course the superb performance of the Elecraft KH1.

The weather was kind, with a gentle breeze keeping things cool. Throughout the activation, I logged 4 contacts, each one a story in itself. Notable among them was a contact from my good friend Steve MW0SAW from across the Bristol Channel in Wales, a testament to the reach of my modest setup. Steve and I had been in the same CWOPS class last year, so it’s always great to get him on air, even though we speak most days on the phone.

By the end of the session, I had made 4 contacts. I was really satisfied and could have sat for longer working the bands but, content, we decided to pack up and go grab some lunch from the nearby bakery in the village of Beaminster. The KH1 had performed flawlessly, and the homebrew wire antenna had once again proven its worth and overall, it had been a successful activation.

Reflecting on the day’s achievements as we hiked back down, the sun now a little higher in the sky, I couldn’t help but feel a sense of accomplishment. Having just completed a 10 week comprehensive ICR course with CW innovations and being a relatively new CW operator, I was pleased that the contacts had come back at a predictable pace. This made copying the callsigns easy. As I complete more activations, I am finding each activation is a unique experience, and today with the Elecraft KH1 was no exception. We are looking forward to the next adventure, with new challenges and new stories to tell.

Back at home, I reviewed the logs and relived the day through the video footage I had been encouraged to make by my family and friends. For those who want to see the activation in action, you can check out this video on my YouTube channel:

73 and see you on the airwaves!

Bletchley Park

Most readers of this blog are probably familiar with Bletchley Park and the significance of this place in breaking the codes used by the axis military forces during the second world war.

The electromechanical systems developed and used here to aid the codebreakers in their daily work led directly to the electronic digital computers of the mid-twentieth century, and then to the modern world as we know it.

After boarding the London Northwestern Railway at Euston station, the hour long train journey took us from central London, through the suburbs, then the pastoral English countryside to the station at Bletchley, just south of Milton Keynes.

Bletchley Park is a five minute walk from the train station at Bletchley, the town of the same name. In keeping with the formerly clandestine nature of the work at Bletchley Park, there are no loud signs to welcome you, just the Union Jack flying over the nondescript visitor center in Block C.

Exiting the visitor center, any ham will quickly spot the three-element SteppIR Yagi perched atop a roof-mounted tower. Also from the tower, a folded dipole extends over the the Block B building which houses the Alan Turing museum exhibits. The other end of this antenna farm is plugged into GB3RS, the amateur radio station for the National Radio Centre of the RSGB.

The friendly and helpful staff of amateurs at the NRC played a crucial role in my hoped-for plan of activating Bletchley Park for Parks On The Air.

Surprisingly, the POTA page for GB-0507 showed only a handful of activations of this iconic location. Seeing as this is a heritage site, I sent an email to the NRC about week before my visit asking for advice on how to be a welcome guest POTA operator.

Note, the NRC is colocated on the grounds of the museum but they are not a part of Bletchley Park. The NRC is a separate organization.

Martyn G0GMB, the Director of the NRC, kindly responded to my enquiry and informed me that individual amateur radio activity is not generally permitted on the grounds of Bletchley Park due to the number of visitors they receive and concerns about RF safety. This could explain the low number of activations.

The sharp eyed will spot the GB3RS beam across the pond.

Martyn suggested I could set up in the overflow car park few minutes walk down the road from the visitor center. While not on the grounds of Bletchley Park proper, the parking lot operation would still be in the spirit of POTA and would reasonably count as a valid activation location.

When I arrived at Bletchley Park on Friday afternoon, I was met by Mervyn G4KLE who was expecting me thanks to a note left by OM G0GMB. Mervyn asked where all my equipment was and I motioned to the pack on my back.

Because my radio and antenna was a low impact, minimal footprint QRP setup, I was told that I could make use of the picnic table just out the side door of the GB3RS shack, with my antenna setup just beside it. This dead-end spot was not on any of the paths frequented by park visitors and my antenna would not be easily visible.

The antenna is low profile

This was a much better arrangement than trying to activate from a car park without a car! I quickly deployed a GRA-GNT micro tripod with center spike pushed easily into the soft ground. The GRA-7350T loaded vertical and a set of short radials provided an SWR of 1.05 to 1.

I chose the QMX as a travel radio while in Britain because with it, the overall kit is very lightweight and compact. With the exception of the tripod the whole kit fits in my carry-on. The GRA-GNT antenna mounting kit has to fly in checked baggage due to several aggressive looking spikes that would certainly be flagged by airport security. Continue reading UK POTA Rain and Shine →
