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.

Gear used:

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).

More Surprises in Florida

7 Comments

by Teri (KO4WFP)

It is Friday, December 29th and my winter-break POTA trip is drawing to a close. My brother Joseph and I are spending Friday and Saturday nights at an Airbnb after six days of camping. However, before we do that, I have two more parks to activate today – Green Swamp Wilderness Preserve (K-5330) and Lake Apopka North Shore (K-8353).

Google Maps

Overnight, a cold front began its march through Florida. We woke to temperatures in the low 50’s and a brief glimpse of the rising sun before clouds took over the sky again.

The drive to our first park – Green Swamp Wilderness Preserve – was a pleasant one. The preserve is divided into five management districts. We ended up in the West Tract as that is what I chose in Apple Maps. There are 65 miles of hiking trails though the tract is also used for hunting, canoeing, fishing, camping, and equestrian activities. There is a variety of habitats in the preserve – sandhills, flatwoods, oak hammocks, river swamp, and cypress ponds.

I chose an oak tree just inside the West Tract entrance perfect for the Tufteln EFRW antenna. A sunny location was necessary as the temperature was chilly in the breezy conditions. As I set up, two ladies rode in with their horses. Salty, a red roan, was unsure of Daisy and I at first. However, he eventually settled down enough to walk by and check out my POTA flag. Being a horse owner previously, I have a soft spot for these intelligent and sensitive creatures.

Salty and his owner

When Salty moseyed on, Daisy and I got down to business. I went straight to 20 meters which had no noise at all. In 35 minutes, I had 20 contacts. I needed to wrap up the activation soon to have sufficient time to fit in the second activation today but thought I’d check 17 meters for any DX contacts. I had four contacts on that band including Etor FH4MN in France!

QSO Map for Green Swamp Wilderness Preserve http://tools.adventureradio.de/analyzer/

In short order, I packed up my equipment and we headed to Lake Apopka with a stop at Costco for gas. On the drive, we saw five sandhill cranes. I had heard sandhill cranes at Little Manatee River State Park while walking Daisy one day. But I never spied them. These cranes were wary of me and the pictures I snapped weren’t great.

We finally arrived at Lake Apopka North Shore which features an 11-mile wildlife drive. The park reminded me of the Savannah National Wildlife Refuge back home in which I’ve spent some time. Lake Apopka is the headwaters of the Ocklawaha Chain of Lakes. The North Shore area consists of former farmlands that are now used to clean up Lake Apopka’s waters by circulating the lake water through restored wetlands thereby filtering it before it is returned to the lake. Those former farmlands polluted the lake with phosphorous which caused a host of problems. Continue reading More Surprises in Florida →

Kneeboard SOTA: INSANE DX with my smallest, most compromised antenna!

15 Comments

I walked out of my front door on the morning of Friday, September 29, 2023, knowing I was going to do an activation, but I had no idea where that might be.

I certainly had no idea it would be one of my most memorable activations ever–!

I knew I had a five hour window to play radio somewhere not too far from my daughters’ classes near the Asheville Airport.

I really wanted to do a SOTA (Summits On The Air) activation, but I’d pulled a muscle in my back and was nursing it a bit.  I knew that an invigorating hike on a long, gnarly trail was not really in the books.

After dropping off my daughters, I sat in the parking lot running through the activation options in my head. There were 5 or so parks within an easy drive. I knew a POTA activation probably made the most sense since it wouldn’t require hiking or carrying a heavy pack.

Then again, I really wanted to do a SOTA activation–the weather was so amazing, I didn’t want to miss out on an opportunity to take in a summit.

I decided that if I took a minimal amount of gear and activated an “easy” summit, then maybe I could get away with a little SOTA without hurting my back. I thought this might be the perfect excuse to do a SOTA activation pairing my Elecraft KX2 and AX2 antenna. I had a lightweight chair and my kneeboard, so in theory, I could set up anywhere on the summit with my entire station on my knee.

Next, I only needed to find the right summit and one came to mind almost immediately…

Black Balsam Knob (W4C/CM-005)

The last time I activated Black Balsam was with my buddy, Monty, in 2021. I remembered that it was an easy hike with stunning vistas of Pisgah Forest (K-4510) and the Blue Ridge Parkway (K-3378).

This it the Mountain Ash (Sorbus Americana) with bright red fruit!

I drove 55 minutes to the trailhead and was happy that there weren’t too many cars in the parking area yet that morning. Black Balsam is one of the most popular summits on the Blue Ridge Parkway, so sometimes it can be a challenge to find a parking space…especially with stunning weather like this!

The hike was very pleasant and my GoRuck GR1 backpack was pretty light.

I knew I’d chosen the right summit hike.

The views from the Art Loeb Trail do not disappoint. (Click images to enlarge.)

In fact, if anything, I wish this hike were just a little longer because I enjoyed the scenery so much!

It’s only 3/4 of a mile one way, so it goes by quickly. Still… it’s why I chose this particular summit. I knew it would be gentle on my back (and it was).

Once I reached the summit, I started searching for a spot to set up. There were quite a lot of folks on the summit that morning, so I looked for a site just slightly off of the main trail.

I found an area on a side trail that provided just enough room to set up my folding chair without disturbing the flora.

Snagging a little POTA QRP DX with the Chelegance MC-750 and Xiegu G106

3 Comments

Over the past couple of months, I’ve been trying to give the Xiegu G106 a thorough workout in the field. This little HF QRP radio is on loan to me from Radioddity who has very kindly been quite flexible about the loan period.

I want to give the G106 a fair shake-out because I believe it must be the least expensive multi-mode, full HF coverage transceiver on the market. Field ops are always looking for portable, affordable, effective radios to take to the field so many are considering the G106.

Of course, you simply can’t get benchmark performance out of a low-cost leader.

My full review of the Xiegu G106 will be in the May 2023 issue of The Spectrum Monitor magazine. It’s one of the longest reviews I’ve published in TSM because I try to fully explore the pros and cons of this pint size rig in order that pretty much anyone can make a purchase decision based on their own preferences and requirements.

POTA Plan B

On Saturday, March 18, 2023, I  decided to take the G106 out for a very brief activation during a return trip to my QTH.

My park of choice was Tuttle Educational State Forest (K-4861) because it’s conveniently located, is an excellent POTA site, and I wanted to fit in a quick hike as well. Tuttle’s two mile loop fit the bill perfectly.

When I arrived at the park entrance, however, the gates were closed. I had double checked Tuttle’s schedule in advance and was under the impression that they had started opening the park on Saturdays again for the season.

I really wanted to fit in a decent hike so the next logical park choice was Lake James State Park. It didn’t require a major detour and I was certain it would be open.

Lake James State Park (K-2739)

Lake James has two major access points: the Paddy’s Creek Access and Catawba River Access.

I prefer the Catawba River Access even though it’s much smaller than Paddy’s Creek. For one thing, it’s always less busy and they’ve better spots to set up for POTA (since I like hanging wires trees more often than not). Although the Catawba River access lacks the trail network found at Paddy’s Creek, they do have a few trails that can be stitched together for a nice workout.

Lake James State Park Map Catawba River Access

After arriving at the park, I put on my hiking boots and walked the Fox Den Loop and a bit of the Lake Channel Overlook.

I hiked back to my car, ate a bite of lunch, then grabbed my radio gear for some cheap POTA fun!

Higher Bands

The great thing about the G106 compared with some of my more affordable QRP radios (MTR-3B, SW-3B, R4020, TR-35, etc.) is that it’s not limited to CW and it covers all bands from 80 to 10 meters. Continue reading Snagging a little POTA QRP DX with the Chelegance MC-750 and Xiegu G106 →

Video: DL1DN’s amazing QRP DX and being aware of uSDR clones

5 Comments

Many thanks to Steve (MW0SAW) who shares the following video of DL1DN making a very enthusiastic contact with VK5MAZ–Germany to Australia–QRP SSB pedestrian mobile:

What an amazing accomplishment! I think I felt as excited as David did in his video. The reception of VK5MAZ was simply phenomenal, too!

uSDR clones

David (DL1DN) mentions at the end of his video that he had been in touch with Manuel (DL2MAN) who is the designer of the incredibly affordable uSDR transceiver project. David had featured a Chinese clone version of the uSDR in some of his previous videos. These days, it’s difficult to know if you’re ordering a clone or the original item because often the clone so closely mimics the original.

As I understand it, the uSDR is completely open source and, at least at time of posting, there is no comprehensive kit version available. However, all of the information needed for gathering parts and building the uSDR are public and free.

Manuel (DL2MAN) made the uSDR project open source with the condition that it cannot be used for commercial purposes (in other words, produced by another party and sold as a product). Of course, it was very quickly cloned by manufacturers in China and is now available on eBay.

David shared a link to Manuel’s recent video speaking about the differences between the two units:

You’ll note that I try to steer clear of clones on QRPer.com. I do this mainly because I like supporting the original developers and designers of radios and kits when possible. I feel like by doing this, I’m supporting the innovators in our community as opposed to taking money away from them.

On that note, I’m in the market for an M0NKA mcHF transceiver!

642 Miles Per Watt with the new Icom IC-705 QRP transceiver

5 Comments

Thursday, I set out to test how long the Icom IC-705 could operate during a Parks On The Air (POTA) activation with one fully-charged Icom BP-272 Li-ion battery pack. This, following my listening endurance test.

I knew conditions were pretty terrible Thursday in terms of propagation, but that didn’t really matter. I intended to call “CQ POTA” in CW until the ‘705 finally shut down due to low voltage. In my head, I imagined this wouldn’t take much longer than 1.5 to 2 hours and during that time, despite propagation, surely I’d work 10 stations to validate the activation, right–?

Sandy Mush Game Lands (K-6949)

I picked Sandy Mush Game Lands as my test site. Since I’d been there before, I knew there were ample trees to hang the Vibroplex EFT-MTR end-fed antenna, and I knew I’d likely be the only one in the parking area as this site is secluded and this was not a designated hunting day.

The Vibroplex/End-Fedz EFT-MTR antenna

Setup at the site was pretty straight-forward. I quickly deployed the EFT-MTR antenna–using my arborist throw line–in a “V” shape hanging over a high tree branch.

I picked the EFT-MTR because it’s resonant on my three favorite POTA bands: 40, 30, and 20 meters. Note that the IC-705 does not have an internal ATU.

Although I have an mAT-705 external ATU on loan to test, I didn’t take it to this first activation–I wanted to keep the set up simple for testing battery endurance.

On the Air

I started calling CQ at 16:30 UTC on the 40 meter band and set the IC-705 to beacon mode call “CQ POTA K4SWL.” No replies for 10 minutes. At that point, I discovered the POTA spots website was down for a scheduled upgrade (I have impeccable timing!), so I posted my spot on the POTA Facebook page.

Then my buddy Mike (K8RAT) sent a text message stating that the Reverse Beacon Network (RBN) had spotted me, but with a very low signal report. Hmmm….why would that be?

Turns out, I still had the IC-705 power level set to “0” watts (this story might sound familiar). Doh!

Note to IC-705 owners: zero watts is not zero watts!

I turned up the power to 5 watts (the max the IC-705 will achieve on a 7.4V battery pack) and was greeted by an instant CW pile-up.

What a blast! I started on 40 meters in CW, but eventually worked both 40 and 20 meters in SSB and CW. I then lowered the antenna, removed the SMA cap on the EFT-MTR coil, and worked 30 meters CW for the remainder of my time.

I logged my first contact at 16:28, my last at 18:18 UTC. So 1 hour 50 minutes of near constant operating.

Remaining battery capacity after 1:50 of operating.

The IC-705 battery pack was still going strong and had about 40% capacity left, but I simply ran out of time as I needed to run an errand in town, so had to shut down the radio and pack up.

I must admit: the IC-705 is doing a much better job managing battery usage than I would have expected. I’m guessing I could have operated for 3 hours or so at 5 watts without needing to recharge the BP-272 1880 mAh Li-ion battery pack.

I do believe I’ll invest in the larger BP-307 battery pack which has a capacity of 3100 mAh. It’s a pricey battery, though, at $130 US.

How does the IC-705’s battery endurance compare with the Elecraft KX2? I’m not sure yet, but I’m guessing the KX2 will have even better longevity as its current drain is less than half that of the IC-705. The KX2 will operate at 10 watts output for about 1 hour 15 minutes with the internal battery pack, before decreasing to 5 watts output. I’ve never tried a battery endurance test with the KX2 at only 5 watts.

Of course, with an external 12 volt battery, the IC-705 will pump out a full 10 watts of power as well.

Five watts and a wire–wow!

The biggest surprise of the day?

I worked stations from Oregon, and Saskatchewan to the Azores…in single sideband!

Here’s a map of my contacts–red signal paths are SSB, CW in green (click to enlarge):

This was one activation where 5 watts SSB actually snagged more DX than CW. Great fun!

While I’d like to think it was a little IC-705 “mojo” on its first field outing, in truth it had everything to do with the EFT-MTR antenna and what must have been a moment of propagation stability.

This was also my maiden voyage with the CW Morse Single Lever paddle. CW Morse sent this paddle, along with their double lever paddle and a selection of straight keys, for me to evaluate. If you’ve been considering an affordable, portable single-lever paddle, this is a brilliant one. I really enjoyed using it and the action is very easy to adjust.

I’m already regretting the decision to send it to my buddy Eric (WD8RIF) for a proper evaluation. (Just kidding, Eric! (Maybe.)) He only uses a single lever paddle for his numerous field radio adventures.

Eric will give this single-lever paddle a proper workout and give us a full report.

I must admit, I had a lot of fun with the IC-705/EFT-MTR antenna combo.

Of course, I’ll be taking the IC-705 to the field a lot in the coming weeks.

IC-705 Questions?

Feel free to comment and ask any questions you may have about the IC-705. I’ll do my best to answer them.

While I love QRP and ham radio in general, I must admit that I’m not much of a DXer. I love the idea of DX, but at this point in my life, it’s hard to make time for it and, frankly, my CW skills are somewhat lacking.

I owe many thanks, though, to my good friend, Vlado (N3CZ), who sat with me yesterday at his QTH and coached me through working K1N on 15 meters CW. It was a bit like learning from a Jedi Master…er, Jedi Elmer. At any rate, it felt good to see my call in the K1N log and to know that I worked a station that may not reappear for another 25 years.

If you have the time and patience, you might try working K1N soon.  I understand the K1N team announced earlier today that they intend to tear down their stations starting this Saturday.  They will go QRT Sunday morning.

BBC World Service interviews Paul (N6PSE)who is attempting to organize a DXpedition to North Korea

Leave a comment

(Source: BBC World Service)

A small group of US ham radio enthusiasts have been in North Korea recently to ask for permission to set up a ‘pop up’ ham radio station there. Paul Ewing is one of them; he wants to lead a group to set up a call sign for two weeks, to make contacts around the world from perhaps the most isolated society in the world. The BBC’s Dan Damon asked Paul to explain.
