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.

 

 

 

 

 

 

 

DD5LP/P – June 15th 2021 – HEMA – DL/HAM-002 Rösenau Kreuz.

Preparation:

The DL association of HEMA came into existence on April 5th after my surveyed summits were accepted. I have been trying to get out and activate the first HEMA DL Summit since then. With equipment problems, COVID lockdowns, bad weather and illness delaying my attempt, I determined to get to this – my closest HEMA summit at last!

Since my last portable operation, I have bought myself a new radio. A XIEGU G90 – I have written a review on it which can be found here.  So this was to be a “trial of fire” for the new radio as well.

I had already visited the summit twice, taking two different approaches. The first was when there was still a lot of snow on the ground and was a long access route. The second visit and this one got my car much closer to the summit, leaving just a 10-15 minute walk up prepared tracks to get to the summit.

The Activation

The trip down to Hohenfurch (the nearest village to the summit) is straightforward using the B17 main road. It wouldn’t have been a few weeks earlier as the whole road is being resurfaced and improved. Further south on this road the main large bridge over the Lech River is closed for a month for upgrades (something to remember as I normally travel over that bridge to get to many of my favourite SOTA summits). As far as I was going all roadworks are complete and after leaving Hohenfirth, I took the road to North Schongau and immediately turned off it onto single track roads to take me to the closest parking point for the summit at (47.83556, 10.91673). Parking at the holy cross next to the ram-shackle farm it’s only a short 10-15 minute walk up the track to the summit. Just keep taking the track that goes upwards and then takes you under the high voltage electricity pylons and you are there. There is no local name for this summit, a lower one close by is the 774m high Schwalbenstein but if you end up there you have gone past the higher 780m summit, which, as it is over Rösenau on the River Lech and there is a small stone cross on it, (at 47.83556, 10.91673) I have called the HEMA summit Rosenau Kreuz. Hopefully, the sequence of photos below will guide future activators to the summit.

The summit area itself is fairly flat and so it’s possible to choose a location in the woods or on the open grassland. I arrived to find that the farmer had his cows grazing but they were in fenced-off areas below the power lines. I did have some pulsed noises on 20 metres during my activation and I wonder if this was coming from the power lines but generally this seems to be a very quiet location and the view down into the Fuchstal valley is amazing. A short walk through the forest gets you to the “LechErlebnisWeg” walking trail that is part of the famous JakobsWeg pilgrim’s way and gives lovely views down to the River Lech. 

I think the combination of the fact that HEMA is a much smaller community than SOTA and a contact with a German portable station, isn’t of a lot of interest to most watching the DX Cluster in Europe, is what made contacts hard to come by.

I was thankful to have contacts with Mike 2E0YYY/P from HEMA summit G/HSP-021 Overmoor on both 40 and 20m. My first H2H contact and the first into the new DL association!

For its first trip out, the new XIEGU G90 performed well. It still suffered from an inexperienced user though. All but my last contact on 20m were made with the attenuator on and the preamp off. Despite that, the few signals that were on the band were strong enough and once the preamp was turned on I still had an S0 noise level! Apart from some annoying pulse noise which could have been coming from the nearby 33KV power lines, both 40 & 20m were very quiet – unfortunately, that also meant not many signals. I was happy to find that the speech compressor in the rig performed a lot better than the one in the X108G which distorts speech when set at any value above 2 out of 10. I actually managed to be able to read the display the whole time, even in sunlight and didn’t have to revert to my external (Android smartphone) display.

I did hear one VK6 station but he was in a net with several other stations and I had no chance of getting in. I was hearing the VK6 at S1 and that was partially due to having the attenuator engaged – I guess he may have been S3 without the attenuator and with the preamp on.

I managed contacts with 5 different stations in all and so I had qualified my first HEMA summit.

  All in all, an enjoyable morning out!

Conclusions:

  • The band conditions were not good and a HEMA summit does not attract as many callers as a SOTA one does, so getting contacts were difficult.
  • The new radio performed well (especially when I turned the attenuator off!).

73 ’til the next summit.
