Trans-Atlantic S2S Event - 4th November 2023 - post-event reports

That was fun!
We must have got some pre-storm enhancement, I did not expect such fine signals on 10m. 50 QSO with lots of NA chasers, 5 x NA S2S on 15m, 5 x NA S2S on 10m and even got called by a LW2DO on 10.

WA7JTM, K9PM/P & N6AN were all nice signals on 10m, Dave N6AN very impressive for 5w with his Half Square.

I used KX2 with internal ATU and 10.9m Inverted L. which is an excellent antenna on 10m.

I activated GM/WS-018 earlier in the day then GM/WS-014 for the S2S event. A successful day with 107 CW Qs between the two summits.

Thanks for all the activity and S2S.

Due to the weather we didn’t activate but did go up to our quiet field and stomped around in the rain and mud.
10m was buzzing, although for personal reasons (maybe more on that in a different topic later) , I actually SWL’d most of the event, although I couldn’t resist keying the mic on a couple of occasions :slight_smile: I very much doubt that anyone failed to qualify their summit due to me not wanting to make a qso.

On returning home and looking up some of the summits, I had to smile at W5N/EL-001 at 2633m activated by K5TFL (I didn’t work them). The EL region of W5N is named Eastern New Mexico flatlands. The lowest/smallest/least height summit in that region is at 1506m which is higher than anything in the UK. Even the differential between the tallest and shortest at 1127m is higher than most in the UK. doesn’t sound very flat to me :slight_smile:

One surprise, was that everyone seemed to cram themselves into the space between 28.3Mhz and 28.45 mhz which on a very busy band had its issues. With 1Mhz (except 28.680 for SSTV) to play with between 28.3mhz and 29.3mhz and an efficient way of telling interested parties what frequencies you were on some of the interference problems could have been avoided. Maybe we are not used to having such space to operate in :slight_smile:

Thanks to all who did get out and especially the ones braving the poor weather. Thanks to K6ARK and AJ2I for the qso on 10m and GM4JXP/P on 40m while I was cosy in the car.

The rain finally stopped here at lunchtime and I was able to make it to my local 1-pointer, Abbey Hill EI/IW-082 by 1525z, less than 90 minutes before local sunset. I risked an untested vertical wire with the IC-705 but it worked out pretty well. 37 contacts 10-12-15m, 21 transatlantic, 8 S2S (2 on phone), furthest S2S was AA6XA on W6/NC-191 (12m cw).

The bands were hopping and I could have stayed longer but I was pushing my luck on time. Headtorch assistance was needed on the descent. It was pitch dark by the time I made it to the car. A very enjoyable event - hopefully wx will be better for the next one.

It was brilliant to be part of this event!

As the weather was expected to be terrible (lots of rain and strong winds) I was looking for a plan B. So I went to the nearby summit HB/BL-015, which has a hut within the activation zone. Unfortunately, you can’t get into the hut, but it has some benches on two sides with a roof that gives enough shelter from the rain and wind. The temperature was around 6C and during my activation I sometimes heard a tree fall due to gusts of wind.
Compared to the previously chosen summit, the take-off is not so good and transmitting from the middle of a wet forest doesn’t help on higher bands either, but it’s better than staying at home!

I was running 10W and carrying four antennas, three of which were set up: a vertical EFHW for 10m, a ground mounted vertical for 10-20m and a compact EFHW for 10/20/40m setup on a 5m pole as inverted-L with a broadband coupler. In the end, 90% of the contacts were made with my tried and tested multiband EFHW.

The result was 69 SSB contacts with many S2S, some of which were DX: 3 to the USA (California, Arizona and New Mexico), Puerto Rico, Brazil and the Canary Islands.

The DX signals were not very strong, probably due to being surrounded by wet trees.
Paul @W6PNG had a very stable signal, mostly peaking 55, but even after maybe 20 S2S tries at different times, he couldn’t copy me. Well, I guess his 65W helped him to be heard better.

Thanks to all!

BTW: For those interested in an updated call/name CSV for portable activation, e.g. for VK port-a-log, I just uploaded a new names.csv file. Please note that I deliberately don’t link to the file directly, as a new upload path is created every month.

That’s a pity. I have to say that most of the chasers I experienced on this event (an average of 1 QSO/2 mins for 2 hrs which doesn’t include time out for band changes and drinks) were very considerate when I called for S2S stations.
It’s been a while since I worked a pile up like that experienced on 20m.
Thanks gents

Someone will correct me if I am wrong, but I think that the concentration on that slice of the band is because it is available to US technicians on phone, making it the optimum choice for transatlantic chases. Activity was scattered up to over 29MHz but that slice was beautifully active! For me the stand-out USA station was K6ARK, who was a good couple of S points stronger than any other activator and on a par with the in-the-shack Americans.

Yes Brian. See this ARRL free pdf of bandplans and access permissions for US stations.

He was the loudest portable station I heard on 10m. Fixed stations on 10m like KF9D were 599 to me and Randy was 579 running 5W but he has a 4ele beam on 10m.

Sorry I couldn’t hear you! Andy @MM0FMF tried also with no luck. My K3s has excellent “ears” but the band wasn’t entirely noise free.

I wonder if propagation was asymmetric as the difference between 10w and 65w is somewhere between 1 S unit and 1.5 S unit. I got a lot of reports from the UK of 57 and sometimes 59 (maybe all the opts had 7 element Yagis!). If propagation had been symmetrical then 10w should have been 54, 55 etc and copyable.

Anyway fun time and sorry we didn’t make a S2S.

That’s correct. When I get on 10m, I try to stay within the Tech portion so those guys can play too.

I got to my summit fairly late, around 3pmEST (aka GMT-4). I started on 10m, but got no responses and moved onto other bands. I was really hoping for some high band T-A S2S action, but it was just too late in the day.

The Transatlantic S2S event coincided with my fall vacation in the Caribbean this year. So an activation on Saturday was a must!
I was lucky with the weather: little wind and only about 15 minutes of rain. On El Yunque there are many telecom facilities, so I took the IC-705 with me, which seems to be a bit more robust against strong HF signals than the KX2, at least I had no problems with local QRM.
My horizontally polarized Oblong antenna certainly improved the immunity to local interference as well.
I was on the summit for just under two hours and was able to make 66 QSOs, 53 of which were DX to Europe and 13 DX-S2S.
Thanks to everyone who activated at home in the really bad weather - it was great fun!

Hi everyone,

My first trans-Atlantic S2S event, what an experience!

Due to other commitments I knew I could only be on the air from 15:00 UTC onwards (the sun sets a bit before 17:00z, so not much time). Still, I didn’t want to miss such an event, so I packed my stuff and headed to one of the quickest peaks I have close to my home: Pic del Vent (EA3/BC-063).

As I was approaching the summit, I started seeing the top of a pole with a wire hanging from it. Yes, had not been the only one that thought about that summit: there I had the pleasure to meet @EA3IKB for the first time! We need to do more activations together, buddy!

I deployed my 100ft doublet as quick as I could, switched on my KX2, and started CQing. I stayed in 10/12/15 for most of the time, and only moved to lower bands in the last minutes of the activation, almost in the dark, mostly to work those Europeans that I might have missed in higher bands.

At the end, 45 QSOs were made (16 of them across the Atlantic) including 9 S2S, in the slightly more than 1h that I could be on the air (or maybe I should say “on the wind”). A pleasure to work @WB2FUV, @KX0R, @AA6XA, @NA6MG, @K6ARK, @AC1Z and @VA3EO, @YO8AGQ and @EA2BD, from their respective summits. Amazing what can be done with <10w and a piece of wire!

Again, thanks to all the chasers and see you in the next one!

Amazing coincidence Roger, yesterday, in the Pic del Vent! Definitively we need to do more activations together!
My plan to work higher bands with my Xiegu X6100 went South because of front-end overloading and I had to resort to my QCX 20m mono band. I bagged a handful of EU contacts including some S2S.
Yet Roger was so kind that allowed me to use his rig and I managed to get a S2S with Arizona! My first ever S2S with NA! That was fun!
When is next NA/US S2S event? Do we really have to wait for one year? Hopefully not! :crossed_fingers:

I had hoped to be running 40W, but the PTT cable has a break in it somewhere. So it was 10W from my KX3 to a linked dipole. Got 9 S2S, 5 of which were to Europe. And, the GM and OE summits were new DXCC’s for me! @EI3KA @EA3M @OE5EEP @HB9DQM @G4OIG
10, 12, and 15 meters were the best from northern California for DX.

Got a nice sunrise while walking up as well

13th Trans-Atlantic S2S event, 4th November 2023

I chose Arthur’s Seat GM/SS-272 close to the centre of Edinburgh for the event primarily because of convenience and I needed to activate the summit to further my goal of activating all the GM/SS summits south of the Glasgow - Edinburgh line. If I’d have thought about it rationally I would have never chosen this summit for a protracted stay as climbing it is one of the “things to do” when visiting Edinburgh. But this was November… surely there couldn’t be that many people up there could there, even though it was a Saturday? Hmm…

After dropping off the XYL close to edge of the main shopping area, I parked up at the St Margaret’s Loch car park at 1030z. It wasn’t very busy… a good sign perhaps? To check out the situation on the hill, I decided to approach the summit from the east which gave me a side-on view of the main path coming up from the direction of the city centre. The path was absolutely crammed with people, both ascending and descending. Arghh, what had I been thinking? However it didn’t seem so bad when I joined the masses on the final pull up to the summit.

When activating this summit Phil G4OBK had used a gorse bush on the east side of the hill to get some screening from public view, but could I find it? There was no option, but to find my own spot. At the summit, the trig point on top of the rocky outcrop was surrounded by about 20 people. No chance to top-out, especially with a 15kg pack on my back. I felt overdressed in my waterproof walking gear and 3 season boots. There were at least 50 across the summit area, with more arriving all the time, virtually all wearing trainers and jeans.

On the north side there is a sharp drop off, but I was pleased to see there was enough of a flattish area for me to set up on… and it was clear of people. Once I had found a suitable spot to operate from, I used an app on my phone to check I was well within the AZ. Setting up the pole on the steep slope needed care and there was only just enough space before the drop off for the radials to fit in down the slope. As I was setting up, a young lady approached me to ask what I was doing. I tried to explain, but I’m not sure she fully understood. A few minutes later another young lady approached me. Thinking I was going to get asked the same question, I was completely surprised when she said, “is this amateur radio?” She introduced herself as the daughter of Simon VK3ELH… and there he was on a video call on her mobile phone! We had a brief chat and I explained what I was up to. The chance of that happening must be infinitessimally small.

Expecting further enquiries as to what I was doing, I decided to run the KX3 barefoot to keep the power down. I started on 20m CW and soon found Scott N1AIA for the first S2S of the day at 12:50z. A thought then entered my head… could I qualify the summit on Trans-Atlantic S2S contacts alone and with KX3 without the amp? SOTAwatch revealed more action on 15m CW, so I retuned the antenna and soon Roy WN3F and Mike WB2FUV were in the bag. Then up to 10m CW to catch Eric VA2EO. Deed done! The Slidewinder wasn’t tuning well above 28.1MHz as the wire is cut a little longer than it should be, but I wasn’t going to drop the mast and invite more questions from the public. The morse key and headphones seemed to keeping them at bay.

At 14:00z with 6 in the log I plugged in the amp and ran 30 watts… the public were staying away. Up until 15:00z I didn’t call CQ, but just went up and down between 20m and 10m slowly picking up S2S contacts. I did look at 17m and 12m, but those bands seemed to be overflowing with signals, so in the end I avoided them. On all the bands my position on the hill was definitely limiting signals from EU. My first 10 contacts were all Trans-Atlantic S2S, with only a quick call to say Hi to Simon GM4JXP/P on 10m SSB for my sole EU S2S contact and sole SSB contact. I had to queue for quite a while to work Fredi KP4/KY0T on 10m CW as he was suffering QRM.

My first CQ session was on 15m CW. This netted the 5 EU chaser contacts that I made, 2 US chaser contacts and 3 more Trans-Atlantic S2S. After this run I was having a snack when up popped Dale AA7OY on the frequency I had been using. Hey ho, another in the log. Moving to 10m CW at 15:55z, Paul K9PM/P was first of the session which netted 3 US chasers, 6 Trans-Atlantic S2S and a second band for Dale AA7OY.

By 16:30z I was starting to get damp from the dew, really chilled and aware my XYL would have spent up some time since, I went QRT. I texted my XYL about my intentions and was on my way down to the car at 16:55z. On the descent I got away without having to use my headtorch, the light pollution from the city providing enough light… and I wasn’t the last to leave the summit. I actually passed someone ascending in the dark.

So, 19 Trans-Atlantic S2S plus the second contact with Dale AA7OY.

N1AIA 20m, WN3F 15m, WB2FUV 15m, VA2EO 10m, VA2YZX 20m, WN2G 20m, WA7JTM 10m, VA2NM 10m, KP4/KY0T 10m, W7CBK 15m, AA6XA 15m, KX0R 15m, AA7OY 15m, K9PM/P 10m, K6EL 10m, NM3A 10m, AA7OY 10m, AB1WX 10m, N6AN 10m, W6ARW 10m.

5 Trans-Atlantic chasers in AZ, MN, CA, OR and NV.

1 EU S2S GM4JXP/P 10m SSB.

5 EU chasers in EA, GM, HB9, US3 and OH.

The getaways were mainly on 10m SSB where I wasn’t heard, probably due to my antenna, although the auto-ATU did tune it okay. I actually ran two auto-ATUs, that in the KX3 ensuring a good match to the amp input circuitry.

So just 31 in the log, but WOW what a log!

Many thanks to everyone that made this event such a success. Special thanks to Pete WA7JTM for rustling up a veritable army of support in W7A. When I first suggested we try this event back in 2016 little did I know how popular it would become. Naturally conditions helped this time, but we still need backsides on summits to make this event viable. Well done all. See you in the Spring.

Hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha takes breath, hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha :wink:

Sorry I didn’t hear you. Would have been a simple QSO as I could see your summit from mine. I could hear Simon GM4JXP working Paul W6PNG on 10m, I think it was backscatter as he was kind of rough sounding.

OK…FINAL WA7JTM W7A/CS-031 RESULTS… I THINK.

95 Q’s:
43 USA
52 Europe
1 South America

22 s2s QSO’s
13 USA
9 Europe

94 CW QSO,
1 FM QSO

BAND BREAKDOWN:
10 M 80 QSO’S
15M 6 QSO’S
40M 8 QSO’S
2M 1 QSO

Some really big signals from Europe this year, and I am sure I missed a number of weaker s2s stations in Europe…at times the QRM was a real problem on 10 Meters.

Additionally I had to QSY MANY TIMES when I had a pileup, because someone decided to take my frequency. As I result I figure I missed working a number of SOTA EU stations due to the QSY…

Maybe operating ABOVE 28.100 for this event in the future might help?

Anyhow, great time, great opening, great results, and lot’s of fun for sure.

Looking forward to next year when conditions are even better!

THANKS TO ALL!!!
