DD5LP/P – June 3rd 2022 – HEMA – DL/HCG-005 & SOTA DL/CG-094 Ratzinger Höhe.

Preparation:

Having activated a SOTA summit last time and a GMA one before that, it was time to get to activate a HEMA summit again. I looked on the map for the next one that I haven’t yet activated and came up with Ratzinger Höhe which overlooks Chiemsee in the east of Bavaria. I was looking for a summit to the east of Munich so that I could activate with Rob DM1CM and as Rob can only do limited climbing this summit looked ideal. The downside was that it wasn’t very close, taking between 90 and 120 minutes to get there depending upon the time of day as I have to drive around Munich, where the traffic can be horrendous at times. As I wanted to start off the activation with a contact with Ernie VK3DET, down in Australia, I would need to be operational by 0700 UTC going by previous experiences. Unfortunately, the radio conditions on the days coming up to the planned Friday were not good and so this might be a case of only European contacts to qualify the summit, which would be my first summit in the DL/HCG region of HEMA and the first time that it had been activated in HEMA at all.

I still need to test out my vertical Moxon antenna on 15m, but with the band conditions the way they were, I was not hopeful however I would take it along in case things were good and the MUF was over 21 MHz.

When looking at the map to find parking and access tracks, I realised that this was also a SOTA summit – this is another case of a sub 150m prominence (actually 136m) being in the p150m SOTA region for historical reasons. As Rob prefers to activate SOTA summits, this would fit well. I would also activate the summit in SOTA after I had finished my HEMA activation as I have not been to this summit before, let alone activated it.

There is also a Gasthaus “Weingarten” (a small hotel with a restaurant open to the public) close by so that would fit very well as a way to round off the activation before heading back home. 

Given the long drive and possibility of unexpected delays, I planned to set off by 06:45 am local time, which meant rising at 05:30, so the plan was to load everything into the car the previous evening so that I could get away with the minimum delay and noise in the morning.

The Activation

The drive took 95 minutes so a good run and the “wanderparkplatz” was easy to find. On arriving, Rob had arrived before me, so at this point, I decided what equipment I would carry up the last part of the hill. The parking spot is actually well within the activation zone, so one could activate from the field by the car parking spot and hence come back easily to the cars for any extra needed equipment. There was also a port-a-loo here should it be needed, not something you expect in a country walkers car park. I decided however to leave the 15m Moxon and also the large tripod and 10 metre mast in the car as I thought band conditions would not be suitable for 15 metres. I later found out that assumption to be true, however, had I been able to arrive 30 minutes earlier, the 15m band was actually open for DX.

In any case, my decision was to take my usual rucksack and equipment (radio, 6-metre mast, screw-in base, etc) and set up with the linked dipole running north-south with the hope of managing a contact on 20 and perhaps 17m into VK.

On walking up the hill through the house and farm shown on the map as “Berg” we passed a small path off to a couple of seats at a lookout spot but continued on to where the coordinates say the real summit it. This was somewhat of a surprise as a bee-keepers club have put their hives and a meeting hut on this spot and several bees were busy leaving and returning to the hives across the public right-of-way. This was obviously not going to be suitable for our activation and so we decided to head back down the road to the first lookout point which indeed carried the Ratzinger Höhe name sign. The lookout spot has two benches under some trees opened out into a relatively flat field and while Rob set up his equipment close to the trees with his small tripod and Komunica Power HF-PRO2-PLUS-T multi-band loaded vertical, I moved further into the field and set up the mast and linked dipole. At this point, I contacted Mike 2E0YYY/P in the UK and Ernie VK3DET in Australia via the Signal App that we use as our “back channel”. I had agreed with Rob that I would start on 20m and he would start on 40 metres and then we would switch. One interesting fact from this activation was that although we were only about 20 metres away from each other neither of us caused the other any interference when using the 20 & 40m bands.

After several tries, I was unable to hear Ernie in VK3 but I did make a contact with Mike who was using the special 2Q0YYY call sign for the Queen’s Platinum Jubilee. As Mike was willing, I then suggested we try 17 or 15 metres – both bands were unfortunately dead however and trying to operate on 15m while Rob was transmitting on 40 metres was impossible as he wiped out the whole band. So another point learnt, the second harmonic of a 40m signal on 20m is not a problem however the third harmonic on 15 metres certainly is!

After working Mike on 20m, I also worked another three stations on 20 metres under the HEMA activation. Rob, who had been activating the summit under its SOTA number on 40 metres then agreed to switch to 20m so that I could get some HEMA chasers who were waiting for me on 40m. After working another 5 stations under the HEMA summit code, I then switched to using the SOTA code and went on to work 14 SOTA chasers on 40m.

After things slowed down, Rob and I agreed to call it a day. It had been quite hot in the sunshine and a nice cold beer was calling from the Gasthaus not far away!

After packing up and bringing everything back to the cars, it was a 2-minute drive to the restaurant, where they hadn’t yet started serving food but cold Weißbier was certainly available. The service was friendly and our waitress understood a lot of English. We were sat in the garden area with a wonderful view into the valley and out to the lake Chiemsee. The food was good quality Bavarian fair and it was a nice way to complete the morning’s radio activities before setting off home. the journey back took longer with delays on the Mittlerer Ring around Munich but after two hours I was back home just before the rains started.

Conclusions:

  • This is a nice (easy) summit with space to test antennas but it is too far to drive to catch the long path DX window into Australia.
  • The two G90s worked remarkedly well close together on 20 & 40 metres (but not on 40 and 15m).
  • The difference between the HF-PRO2 on a small tripod and the linked dipole on a 5-6 metre mast is not as great as I would have expected. We both covered Europe and into the UK.
  • We both used Eremit 4Ah LifePO4 batteries and had no problems with them.
  • The ability to compare similar sets of equipment is very useful when the operation takes place around the same time and from the same location.

73 ’til the next summit.
