DD5LP/P – May 30th. 2017 – DL/EW-001 Wank.

Preparation:

Wank is an easy access summit. As you will have seen from my earlier posts, I like summits that my wife can accompany me on and that means access with a cable car to a summit with a restaurant on it. This one has two restaurants on top of it. I was surprised to realise that the last time I activated Wank was in 2014. I have no idea how I missed this summit in 2015 and 2016. If you have read my last couple of reports, you’ll know that I have had problems with both of my HF dipole antennas. I managed to break the centre feed insulator on my SOTABeams Band Hopper linked dipole antenna and the wires coming out of both sides of the BALUN on my Aerial-51 404-UL OCF were frayed. Both antennas have been repaired and this activation will be used to test out the repaired antennas. I also still want to try to get some 2m SOTA contacts just using a HT with my new RH770 antenna, so I’ll be taking that along as well.

Looking back at my report from 2014, I saw that I had some problems finding somewhere to support my mast, so this time I decided to take my sun umbrella screw-in base with me with the hope of finding some softer ground.

The rest of the kit will be the usual FT-817ND plus my 25/35w amplifier and my 6m LambdaHalbe fibreglass mast and as noted above the Wouxun HT and antenna will also be packed.

The Location:

The Wank mountain is located above Garmish Partenkirchen on the Bavaria / Austria border about an hour and a quarter from my home QTH. The cable car takes about twenty minutes to get from the valley to the summit. Technically interesting is the fact that the 4-seat cabins actually run on two cable car systems changing from one to the other at the middle station. You don’t need to move from one car to another, the car changes over between the systems. So to reach the summit, stay in the car, don’t get out when the door opens at the middle station. From the mountain station (where the Sonnenalm panorama restaurant is located) it’s a short walk and about 40 metres climb up to the actual summit, where as well as the Wankhaus restaurant, there is also the Cross and several transmitter stations and their antennas. There’s actually an amateur radio repeater in one of these huts.

The Activation:

My in-car GPS is a couple of years old now and has reported non existent speed cameras around Garmish Partenkirchen the last couple of times I have driven through there, so I had updated the speed cameras file on the card and, even though I knew the route, I let the GPS Navi, tell me the way there and indeed, no more false warnings! I also tuned into the American Forces radio station (Garmish is one of the last remaining locations for the American forces in Germany, kept as a rest and recuperation resort in the most part for soldiers returning from conflicts before going home). It seems they have reduced their 90.3 MHz FM transmitter power down to 50 watts so that it only now covers the base and the town. Previously I could receive it from a lot further away than I can now (or perhaps VHF propagation was a lot better the last time I came through?). Interesting for a change in style of broadcasting compared to the German stations in any case.

The drive down was uneventful and thankfully, this being a week day, the cable car was not busy and I got a cabin to myself both for the trip up and down, allowing me to take some photos using my smart phone (see below). I arrived pretty well on schedule and sought out a spot on the very summit (although there is a large area within the activation zone if others come to activate on a busy day). Indeed here I found what I found last time – only brush wood – none of it strong enough to support the mast, so I took out the sun umbrella base and found some soil where I could screw it in, with enough room at each side to run the antenna out without it obstructing any of the paths. Although there are also some nice bench seats on the summit, none were near enough for the antenna lead, so I got out the trusty painters sheet (a thick PVC sheet) and put it down on the rough rocks and then pulled out and set up the rest of the gear.

Although this summit is high, it seems none of the towers are a cell phone repeater and Internet access was patchy. I tried both of my Networks, Deutche Telekom and Vodafone. I suspect the problem was, that being so close to the Austrian border, the phone was switching back and forwards between roaming mode to an Austrian phone network and my local cell networks.

My first transmit test unfortunately showed that my amplifier wasn’t going onto transmit. I use RF triggering, rather than a PTT line to switch the amplifier into circuit and at the time I thought that it could be something in this circuit that had failed. After getting everything home and taking a look inside the amplifier however I found the main fuse had blown, which is the past has been caused by one of the two push-pull power transistors shorting power to earth. I will need to confirm this and repair it before my next activation. For now however, on the summit, I took the amplifier out of circuit and packed it away, connecting the lead from the SOTABeams linked dipole antenna which I had put up, directly to the FT-817 and ran the whole activation at 5 watts. Even the unsuccessful (no calls) two metre part of the activation was at 5 watts as that’s what the Wouxun HT puts out on 145MHz. So this was a true QRP activation on all bands used.

Given that I made 26 contacts across 40m and 20m in about 45 minutes, I think even at only 5 watts I was still getting out, albeit some people were having more difficulty than usual in copying me.

As is often the case, I had one couple come up to me and ask what I was doing, they were interested to hear that our hobby and technology exists but I don’t think they will be looking any further into it. It was a nice short chat in any case.

The bottom half of the 40m band was full of interference, I suspect from one or more of the microwave transmitters on the summit. 20m was clear of interference and the easier band to operate this time around.

All in all a nice activation and at around 1pm local, I was already back in the cable car heading down the mountain, to both miss the forecast incoming storms (that never came) and also to be able to take care of some chores when I got home.

For those visiting southern Germany, this is a nice summit to visit, easy to activate and even nice for any non-radio people coming long. I certainly wont be waiting another 3 years before activating this summit again.

Conclusions:

A nice activation weather wise, luckily the threatened storms never arrived.

The repaired SOTABeams band-hopper worked perfectly which is more than can be said for my amplifier but as long as the FT817 continues to work, even 5w gets out when there are a lot of chasers looking for you. The repaired Aerial-51 still needs testing, that’ll have to wait for the next activation.

Two metres was a disappointment again, despite this really great location. Sad but it seems 2m SOTA is not very popular in Southern Germany.

73 ’til the next Summit!

DD5LP – SOTA EUROPE – June 8th. 2014 – DL/EW-001 Wank

Preparation:

I had the Wank mountain on my list for some time, as it is one fed with a cable car, with a nice restaurant on top of it with the ability to sit outside in the fresh air and admire the views (all pre-requesits for my wife to accompany me). Yes, easy access makes the activation easier for me as well but I tend to keep these summits for when my wife wishes to come along.

The name of the mountain has an unfortunate meaning in English but who is going to change the name of a mountain, just because the Brits and Yanks don’t like it?

The Location:

Wank is one of the mountains close to Garmish-Partenkirchen near to the Bavaraian border with Austria. It’s around an hours drive to the valley station of the cable car from where I am currently living, depending upon traffic. It actually took an hour and a half because of heavy traffic into Garmish but we had allowed a lot of time in any case. The cable car is one of the older ones with small 4 seater cabins and the ride takes about 20 minutes which meant that we were on the Summit, about 30 vertical metres above where the cable car stops within 2 hours of leaving home.

The Activation:

As Glenn VK3YY was in the UK on business and intending to activate Shining Tor (G/SP-004) I have made a provisional sked for 1200 UTC on 40m SSB. Tony VK3CAT on a canal boat in France might also be available for a contact around the same time if we were lucky. We were already at the summit well before this and so had a leisurely lunch before I went to set-up.

Setting up did not go to plan as I wanted to run my dipole roughly NE to SW however on all the land around the summit putting my antenna up in anything like this direction would mean the wires either crossing a walking track (of which there were several, all being well used) or it would mean I would have to climb down one side of the mountain to attach the end of the dipole/guy wire. In some locations both would be needed. The only place I found where it was safe to set up the antenna was alongside a walking track where there were some bushes. This meant that the dipole antenna ended up running roughly NW-SE meaning it would be almost end-on to both Glenn and Tony. However I had no choice in the matter. This is one situation an Alex Loop Antenna would have been very useful.

There was lots of activity on 40m in general and I hit again the problem that strong signals on adjacent frequencies made it difficult to work weaker stations (hopefully I’l be able to get an IF filter for the 817 at a reasonable price at Friedrichshafen in a few weeks time). I managed 4 Summit to Summit contacts in the hour that I was operational and one of those was indeed with Glenn M/VK3YY/P after we moved to 20m where there was less QRM and conditions good for inter-Europe contacts. I worked 22 stations in all (log below). The contact with Glenn was also special as it was my second G summit and that has pushed me to Silver award level in the Mountain Hunter award – thanks Glenn.

Conclusions:

All in all this turned out to be a very successful activation. The icing on the cake was that my wife asked if she could come along to another activation, possibly next Saturday if the weather stays fine!.

Lessons learned – take some Amateur Radio hobby brochures along, There were lots of  people asking me what I was doing and seemed genuinely interested. There was also a German amateur stopped by (sorry I didn’t note his call sign down), who used to work HF but after moving found to much QRM at home and now only operates VHF/UHF repeaters and a little HF mobile. I think after seeing me he may look into SOTA or at least portable operation in his local park.

73 ’til the next Summit!
