Chasing from the University Club Station DK0PT in the 2026 VHF/UHF Challenge

Dear reflector,

I wanted to write about this for a long time, and I figured that reaching 500 unique chased summits this week was as good a reason as any! We’re also already about two-thirds of the way through the 2026 VHF/UHF Challenge - so this time, I’m actually making a post! :joy:

My goal with this post is to share some of my activity as a chaser and, hopefully, motivate others to give VHF/UHF a try over the next four months if they haven’t done so yet. You might be surprised by just how much is possible!
I’ll save the long story for a possible final post after the challenge. For now, I just want to tell you the following after showing you the following plot, which I will explain in more detail later.

I’m lucky to be able to use the university club station DK0PT spontaneously most of the time. Over time, I gradually started to realize the potential of 2 m and began working stations in the Alps, around 150–200 km away, on 2 m FM. But there was always the same struggle. We have a large directional antenna on the roof, but all of its benefit is lost on FM because of the different polarization. It has happened many times and still happens today on SSB, that I hear absolutely nothing from an activator. Then they switch polarization to horizontal for me, which can be as simple as holding the FM handheld horizontally, and suddenly I hear them loud and clear!
One of these 2m chases before the challenge in particular stands out. On 12 December 2025, I was at the station chasing some shortwave when I noticed a spot from Adam @OM2ADM on 2 m SSB from OM/TN-001, 480 km away. Without a doubt, this summit is a top location, but I thought there was absolutely no chance of making the QSO. But if there’s one thing I’ve learned in amateur radio, it’s that it’s always worth a try. So I switched on the other radio and heard him immediately - even though the antenna was pointing away from him. When I turned it around, he was booming at 57! :fire: This must have been some above-average tropo conditions, and it became one of my most memorable QSOs of 2025.
I continued chasing SOTA stations in the Alps, often struggling to hear the FM stations because of the different polarization, while dreaming of SOTA activators using horizontal antennas paired with SSB and CW. And what can I say - without even knowing it, my dream was about to come true when I heard about some kind of VHF/UHF Challenge being announced towards the end of 2025! :heart_eyes:

Now I have to be careful, because there are way too many activators I would like to thank! But for now, I’ll just tell you the beginning of the story.
I wasn’t able to access the club station during the winter break, but on 3 January 2026, I made my very first Challenge QSO with Michael @OE5HKT, whom I already knew from 2m FM. Towards the end of 2025, he had always been up for trying horizontal polarization for a sked with me. And countless SSB QSOs with him have followed since then this very first one. :blush:
On the same day, Sebastian @DL8MEK, Peter @DC6PK and Armin @DF1AI were activating the little hill Högl DL/CG-107 together, booming in on 2 m SSB from 142 km away. That was the moment when I finally realized just how much potential this challenge opens up.
On 9 January 2026, my first 2m CW QSO followed with Alex @DL5AZZ. And soon after, on 13 January, I worked Arthur @HB9CEV on CW for the first of many times - the QSO I consider my first 2m DX SOTA chase!
This was soon followed by the first of many 2m CW QSO with Chris @DL1CR on a small hill in DM/NS, breaking the 400 km mark for the first time!
I could write multiple pages about all the QSOs I’ve made this year, but the time for that might - or might not - come.

Meanwhile, I’ve worked 513 unique summits in the challenge this year. 389 of them were worked from DK0PT, and 189 were worked as S2S QSOs (with some overlap of course). The plot above shows all the QSOs I’ve made from DK0PT this year. I’m incredibly grateful to be able to use such an amazing antenna with 4 × 12 elements for 2m almost every day. I really feel like I’m in just the right place at just the right time! :face_with_hand_over_mouth:

I’m really looking forward to seeing what the final four months of the Challenge will bring! I’m hoping to get at least one I and one OM summit into the log from DK0PT (I worked both for a S2S) - and maybe even a F summit to add to the FL ones I’ve already chased. :italy: :slovakia: :france:

I want to encourage everyone to give 2 m VHF/UHF from a summit a try this year! You can make some amazing contacts, especially during the contests, when there are plenty of DX stations on the band. And if anyone is interested, I’m always happy to try a sked with you! Preferably on 2 m CW with some kind of directional antenna - the bigger, the better! :blush: :joy:

Great speaking with you this week. I look forward to many more while I am here in DM/BW.

Earlier this year, a fellow hobbyist remarked that this 2m SSB/CW challenge was something for older gentlemen with their even older equipment.

Congrats, Thomas, you’re proving that wrong. You’re young, and your equipment is even newer. It’s your passion for this topic and at the same time your patience that make such a wealth of interesting experience possible. The challenge is not my thing, I have to admit, but I’m happy for your success!

Thank you for beeing a smal part in this big challenge.

Since I don’t have a suitable location for 2m chasing, my best chases are S2S.

That is impressive. Thankfully the honor roll list is divided into countries :slight_smile:

My 55 unique does pale in comparison, but for a UK based amateur its a good haul. 95% of my qso are all vertical polarisation with an omnidirectional white stick. I have managed to work into Italy (non summit) using this setup during an E’s opening earlier this year.

I’m now finding that getting new uniques is the thrill and trying to eek out a qso to summits that are just on the edge of my range (around 200km)

Its a shame some people think this way ( I know this isnt your thoughts Markus). Most of my qsos have used equipment less than 10years old (the white stick on the roof is the oldest). I’m in my mid 50’s and consider myself to be at the younger end of the majority of amateurs.

Hopfully people like Thomas and their enthusiasm can ecourange more younger people into the hobby.

Great story, Thomas!
Your optimism and willingness to experiment have definitely been contagious. At the beginning of the challenge I thought “2m SSB probably won’t work anyway” – especially from the low wooded hills in my vicinity. Now I’m always happy to give it a try, and especially enjoy our CW QSOs.

Thanks for at least a dozen QSOs on VHF and for being a big part of the challenge!

Sorry I was not yet able to answer yet. I am quite busy this week. But I want to share a little update here.

A few months ago, I was browsing sotl.as, when I realized that the line of red summits in the Alps stretches all the way to the Mediterranean coast. Especially the summits in the Southeast of my following screenshot should have an amazing takeoff in my direction, at around 30°.

Some time ago, I sent an email to Beppe, I1WKN, after noticing that he had activated a few Italian summits on 2m SSB and had already made SOTA CW QSOs before. I asked him if he would be up for a 2m CW sked sometime in the future.
Time went by, but on Saturday I noticed that he was now active in exactly that region. Then, yesterday, on September 2nd, I happened to spot him on 40m SSB. During our QSO, he told me that he would later be QRV from another summit with his 6-element Yagi.
I was curious to try. This was the chance. There is not much SOTA activity on these summits. Especially no other 2m activator with a Yagi and knowledge of CW! :eyes:

In fact, he was able to hear me later from I/PM-172 on 2m SSB, but I wasn’t able to read him. He was only running just 4 W into the Yagi. I must have been a bit annoying, as I asked for CW a few times. I was wondering why he didn’t want to switch to CW right away.
When we finally started the QSO on CW, I was able to hear him relatively well, but I realized, that CW was probably not his typical mode. In fact I checked his profile later and noticed, that he logged just a little over 50 CW QSOs compared to 30000 SSB QSOs! Considering that, I am even more thankful that we gave CW a try, and he did a really good job copying my RST and, especially, the 6-digit LOC, which I found challenging at the beginning of this year!
This QSO will definitely stay in my memories, as it was my first SOTA chase of an Italian summit from DK0PT and, at the same time, my all-time SOTA 2m ODX. For the first time, I broke the 600 km mark, with an amazing distance of 618 km according to the SOTA database! :italy: :partying_face:

And then something even more impressive happened. I told Kevin DK5KMA already before, that I will try a QSO with Beppe I1WKN, who is on a very good summit for us with a Yagi! After our QSO, Beppe switched back to SSB and I told him to leave his antenna pointed towards Germany for now. I wasn’t really able to hear Kevin, and especially not Beppe, on SSB for most of the time. But then I suddenly realized, that Kevin was sending his report and locator! For a short time, I was even able to read Beppe on SSB, while he was in the QSO with Kevin, whitnessing this absolutely stunning 2m SSB SOTA chase with a distance of 722 km! Congratulations! :exploding_head:

I made this plot, to see, which mode I used to chased summits at which distance. This plot does not just include the QSOs I made from DK0PT, but also all other 2m SOTA chases, which are moslty S2Ss and also multiple contacts with the same summit.

There are two things in this plot that I want to point out in particular. You can see the big number of QSOs between 125 and 225 km with DL and OE alpine summits. 2m activity in these regions is high and many operators are taking part in the challenge. Especially the summits in the first row of the alps provide great opportunity for 2m!
And you can see the power of CW, which becomes the dominating mode for me for distances of 350 km and more. All opeartors I know are able to work SSB, but not all are able to work CW. At these distances, CW often made the decisive difference! I want to encourage everyone to give CW a try :grin:

Thanks for the many great QSOs during the last week. With your setup of the Yagi paired with 50 W, we have already been able to make SSB QSOs of up to 400 km! :partying_face: But of course CW would yield better rapports and make the communication more stable with the same setup.

Thank you for your kind words, Markus. I think this challenge proves, that 2m is still contemporary. And while one a summit, it just makes sense to make use 2m! I would have loved to work you on 2m this year. Especially as you would be able to try 2m CW with me, where I had great success this year with Arthur @HB9CEV so far, but I always enjoy working you on shortwave, too! :blush:

Here I want to point out, that I don’t want to compare my results in the challenge with anyone in the sense of seeing “who is better”. My chasing from the club station can not be compared to anyone chasing from home. And 2m is absolutely not comparable between places being apart some distance.
What I love to compare though is technical things like that Kevin was able to work Beppe I1WKN with a distance of 100 km more than me on SSB, while I did not have a chance to make a SSB contact. Kevin has an amazing takeoff from his QTH to the south, which most probably made the difference here. :slight_smile:

Congratulations to the Es QSO. A great contact even if it’s not a SOTA chase! I was not able to work Es yet. I am hoping for the coming years. And working summits up to 200 km away on a vertical is also a great achievement. The most important part is having fun while sitting in front of the radio. :flexed_biceps:

You are right. I even chose low SOTA hills as my QTHs for some contests recently with trees on top to have some shade during the hottest time of the year. And I was surprised what’s possible! After all, these summits are good locations for 2m compared to stations at home. And it seems like a few trees don’t hurt that much with horizontal polarization. :smiley:

I am looking forward to a S2S with you on the weekend, Roman!
