DD5LP/P – April 12th 2022 – HEMA – DL/HAM-002 Rösenau Kreuz.

Preparation:

The weather had been very changeable – not uncommon for April but the radio propagation had also been very noisy with the K Index peaking over 6! When the opportunity came for a day out in the sunshine with good radio conditions, I decided to jump at the chance.

I decided to activate my closest summit, as I have not activated it this year as yet. My hope was for a nice warm and sunny morning with contacts around Europe and some DX. The standard equipment would be used – the Xiegu G90, 6m mast and SOTABeams linked dipole, which I have added a link into, to allow it to operate on 17m.

As the summit is a 20-25 minute drive from home my rucksack was prepared and with the mast and the screw-in sun umbrella base, left ready to pick up on Tuesday morning with an around 8 am local time (0600 UTC) planned.

The Activation

The trip to the car parking spot for the summit was uneventful. The walk up to the summit area as well, so by 06:45 UTC (8:45 am local). I was set up and ready to try for contacts on 20m. I was a little earlier than I had told Ernie VK3DET, so I sent him a message via the Signal messenger and when I got no reply decided to tune around. At which point I heard Dave VK5MRD in Adelaide South Australia, booming in and called and had a nice short conversation with him. The band was well open as I was also hearing VK4 and VK2 stations, unfortunately, others in Europe and the US were also hearing them and I had little chance to contact them. At this point, I got a reply from Ernie, who was heading for his radio shack. After searching to find a clear frequency at both ends we eventually managed an easy contact and we decided to try 17 metres as well. Mike 2E0YYY was also monitoring via the hack green WebSDR. Mike could hear Ernie but not me on 20m, which is the usual situation when the skip is long. He could hear neither of us when we went to 17m and indeed we also had some difficulties but managed a basic exchange with Ernie being 5-3 with me and I, 4-3 with him. After we finished on 17 metres I checked the band and there were NO other SSB stations audible on the band, so I think we were very lucky with the timing of our contact! I’m happy that the new link for 17 metres in the dipole works fine and Ernie is looking forward to when he will have his log-periodic beam up again (this contact was made using his 20m beam). 

Mike then suggested I try 40 metres to give some HEMA chasers a chance at this rare summit. Mike reported he was hearing me very strong on 40m into the UK however I hit the problem that is becoming more and more common in Europe these days. The band was full end-to-end with signals, many of them splattering over large sections of the band. Once I found a free frequency there was no guarantee that I would be able to keep it with stations simply starting up on top of other stations without listening first. I managed one Swedish, one German and one Italian contact on 40 metres, all of whom were booming 59++ signals but others had no chance of getting through. I am fairly sure that I heard at least one UK station but as soon as I started to understand their call sign the splatter from a mega-station a couple of kHz away would wipe them out.

After an hour and a half on the summit and the temperature not rising from about +2°C, I decided it was futile trying to get any more contacts on 40 metres and decided to pack up and head home, happy with the easy VK contacts on 20m at the start of the activation and very happy with the contact with Ernie on 17 metres.

Conclusions:

  • While the weather was sunny (which lifts the spirits) it remained cold which was a disappointment however I do not regret going out as the next days looked like they would be a lot worse both weather and radio conditions wise. It’s good to be able to “grab and go” when the opportunity arises.
  • I was really happy with the 17metre contact with Ernie VK3DET and the ease of the contacts with Dave VK5MRD and Ernie VK3DET on 20 metres.
  • Thanks to Mike 2E0YYY who rounded up HEMA chasers for me but the QRM from other stations on 40m made it impossible for me to hear them.
  • It’s time to re-check the solder joints on the linked dipole as at one point it gave a high VSWR for no apparent reason.

73 ’til the next summit.
