DD5LP/P – April 28th 2022 – HEMA – DL/HAM-015 & SOTA DL/AM-156 Schneidberg.

Preparation:

As conditions between EU and VK are so good at the moment, I decided to head out early to another summit and try out 17m as well as 20 & 40m (possibly even 15m).

As explained last time HEMA strictly adheres to its rule of including only summits with a prominence greater than 100 metres and less than 150 metres. For historical reasons, SOTA summits are not always over the SOTA rule of a minimum of 150m prominence.  Schneidberg is another such summit with a prominence of 103m.

With the long path window to VK, starting earlier and earlier, this would be an early start, getting up at 5:30 am to be on the summit by 8:30 am.  

The plan was to activate the summit as a HEMA summit for 30 minutes and then switch to SOTA. Alongside this, as this would be a Thursday morning we would try to get the “Comms Testers” net together. This consists of Mike 2E0YYY in the UK and Ernie VK3DET and Ian VK3YFD (both in Victoria, Australia) and myself in Germany. Mike also said he would go out portable to add to the fun.

I would again stick with the now tried and true configuration of my Xiegu G90 radio and linked dipole antenna on the 6m mast with everything fitting into or onto the medium-sized (40L) rucksack.

The Activation

The weather warnings were for frost however a bigger problem was fog which slowed the drive and caused me to miss a turn near the end of the trip, causing me to lose time. Despite that and the long walk from where I park the car, up to the summit, I did manage to be there, with all equipment set up by 08:15 am local time (06:15 UTC).

The activation did not start well. It’s not just the continental operators who need to go back to radio school one Welsh station forced his way onto a 20m frequency I had been on for 10 minutes and was in a QSO with Ernie VK3DET on. He could hear me telling him the frequency was in use and deliberately kept calling CQ over the top of Ernie and me. This is unacceptable behaviour and had the attitude of I have a 1KW amplifier and a big beam so you can go away and find a different frequency. What was really silly was after two contacts, he decided to go for his breakfast at which time Ernie was already on a different frequency. 

Putting that behind us, on the new frequency, I managed contacts with Ernie, VK3DET, Ian VK3YFD and Mike 2E0YYY/P – so we had the net complete and I had three of the four contacts that I needed to qualify the HEMA summit. Duncan MM5AJN/M on Aberdeen Beach then joined us and I had my needed four contacts. Rather than just continuing on 20m however, we decided to try 17m, so the mast came down and the links came out for 17m and up went the antenna again. Contacts with Ernie and Ian were again reasonably straightforward as they were both putting strong signals into Germany. Try as I may though, I could not get Mike into the log on 17m. Mike was hearing and able to work the guys in VK though, so I left them and went off to find another frequency, spotted myself on the SOTA cluster and see if I could qualify the SOTA summit just with contacts on 17m.

First was Jack from Finland OH3GZ and then with much stronger signals came Ron VK2AFW and Colin VK3GTV, both of whom I have probably not worked for over 5 years – that was a nice surprise.

As no more calls came I went back to the group to find that they were now moving up to try 15m. While I don’t have a “true” 15m link in my dipole I do have some 1 micro-henry plug-in links that should make it possible to use the linked dipole on 15m while it is set to 40m, by substituting both links at the 20m stages with these extra inductances. When I set up my antenna this way, although I could hear some stations on the band, I could hear nothing from Bernie or Ian. I put this down to conditions (apparently the Kp Index had gone up to 4 which can easily suppress the MUF). I was wrong, while setting up to go back to 20m, I realised that I had not closed one of the 17m links, so it’s no wonder it didn’t work! I couldn’t ask the guys to go back to 15m again so I left it for another day and we had a short QSO back on 20m again.  

At this point, Mike texted me that a lot of SOTA chasers in the UK were waiting for me on 40m, so I agreed to move to 40m and hope to find a free frequency (something that as it was getting close to 10 am would not be easy). 

My first contact on 40m was an S2S call from special event station TM2IF/P on F/CR-216. I only found out later that this was a special event station in memory of a recently lost to Cancer and much loved Spanish SOTA activator, Guru EA2IF. I wish I had realised it at the time. Congratulations to Alain F5ODQ for organising the special call sign and I hope that through its use we will all be reminded about all the good things that Guru did for the hobby before he was taken, far too young, from us. 

I then continued to work three more stations on 40m but although I could hear Mike 2E0YYY/P, he could not hear me. The reason became apparent when I was packing up the station. I had managed this time to leave one of the 20m links open when moving to 40m, so the antenna was one half 40m quarter-wave and one half eighth wave, no wonder it was not working well! The ATU in the G90 matches just about anything, so I didn’t notice a horrible SWR which would have been apparent if I had been using a radio without an inbuilt ATU. 

At 10:10 am local time, I packed up and headed back down to the car as with the winds increasing, the temperature had been dropping with the wind-chill factor taking the temperature back down towards zero centigrade.

Conclusions:

  • The weather got colder as time went on, due to the cold winds increasing.
  • The main purpose of the activation – was to try out 17m and indeed that went well, even though 20 & 40m were fraught with QRM and idiots. 17m does seem to be a better band to use for DX communications when open.
  • I had two times when I accidentally left one of the links in the dipole open when it should have been closed. I need to find some way to be able to see this from the ground as the radio matches into anything when asked and hence the usual “bad VSWR” that would tip me off to a problem is hidden.

73 ’til the next summit.
