DD5LP/P – May 19th 2020 – DM/BW-078 Römerstein & DM/BW-484 Bussen.

Preparation:

Wanting to get back into the activating frame of mind now that the weather has got somewhat better and after a couple of cancelled attempts (because of the weather), I was planning an activation of Schwarzer Berg DL/MF-082 but it is quite a long drive away from my home. If I could link up another summit with it that would make it more worthwhile but as the cable cars and seat lifts are all still stopped because of the Coronavirus, (UPDATE: they will start again on June 1st) there was no easy second summit to include. I then started thinking, that if I was to invest an extra 15 minutes over 1hr 30mins in driving time to get to the bottom of this 1 point summit, I could go in the opposite direction into the DM/BW or DM/BM regions which tend to have easier to access and higher scoring summits than in the DL association.

I have activated Römerstein previously and for a 10 point summit, it is easy. I knew I hadn’t activated it this year but when I took a look, I saw I hadn’t activated it since 2017 – so in 2018 and 2019, I had missed out on these easy 10 point activations. While looking at the approach to Römerstein I found a new car park and track coming up from the other side of the hill which was a lot shorter. What I was to find out later was that it was shorter because it was steeper – but more of that later.

So if I’m travelling so far, why not combine a second summit with Römerstein to make the journey worthwhile? Previously I have combined Teck which is relatively close to Römerstein however as the summit is covered by Castle Teck which is closed due to COVID-19 and it is highly likely the car park and the track up to the castle are also closed. This is probably not the best choice, therefore. I had combined Bussen with Römerstein before as Bussen is “sort of”  on the way home (only on the map is it sort of en-route but you certainly would not normally take a route past Bussen from Römerstein as it’s all slow windy country roads in contrast to the mostly Autobahn route I would take to go to Römerstein). In any case with the fact that Bussen would be open as it has a church and other facilities on it that are now allowed to be visited, Bussen (DM/BW-484) it would be.

As I now have the portable amplifier “tamed”, I wanted to use it along with the Xiegu X108G and the repaired-again linked dipole as being a good strong station. Should the bands be bad the extra power helps as does the dipole antenna. I had also scheduled a possible contact with Ian VK3YFD in Australia. To make sure the antenna could bring the most advantage it could I packed the 10m mast and the Surveyors tripod as its support, but I decided to take the 6m mast as a backup as well. You can probably see where this is going …. far, far too much weight to carry to these summits even before I had the surprise of the steeper than expected path up to Römerstein!

In any case, in order to get a good start, all the gear was loaded into the car the previous evening to enable an 8:30 start. My calculations indicated a full day returning before 6pm.

The Activations:

The alarm didn’t get a chance to go off as I awoke 10 minutes before and turned it off. I was on the road by 8:20 am local time – my target was to be set-up and operational by 11am local (0900 UTC). The GPS Navi in the car told me I would need 1 hr and 45 minutes to get to the village of Römerstein – the GPS wouldn’t recognise the actual summit, but I had programmed the new car park’s location into my phone in Google maps in case I got lost. The trip did not follow the route I expected. Just before Ulm it diverted me off the Autobahn onto a B-road that I would follow almost all the way to Römerstein. I would have preferred to stay on the Autobahn network longer and turn off later but the GPS system believed going down this B-road would be quicker. There were no major delays and indeed I arrived in Römerstein pretty well on schedule.

DM/BW-078 Römerstein:

As I had been in the area before, I knew that the Römerstein summit and lookout tower is close to the road from the Römerstein Village to the Donnstetten village. So I programmed Donnstetten as my next destination and I was soon on the road that I recognised and finding the new (to me) car park on the K6704 road was straight forward.

After unpacking the completely filled rucksack and the surveyor’s tripod in which I had also packed the 10 metre fibreglass mast from the car it was time to set off up the track. The start is not bad and the route is signposted so there is no danger of taking the wrong route. Then the track started to get steeper and both the tripod and rucksack started to weigh on my shoulders. Perhaps I should not have packed the kitchen sink and anvil?

Eventually, I saw the tower and realised I was approaching it from the rear. I had expected to be coming up past a scouting hut but that must be another access route. Perhaps I should try that one next time.

As I arrived on the parkland in front of the tower another small family group arrived and took up residence near the fireplace where they would later cook their lunchtime meal. I went ahead and set up the tripod and mast followed by the rest of the station – which I sat on a convenient wooden camping table of which there are several around the place. All was looking good. I sent out an email to Ian VK3YFD to let him know I was almost ready and which frequency I had found free on 40 metres (where I had decided to start). Something didn’t sound right though. Although while tuning around I could receive strong stations and they were very clear, when I tuned off the stations there was no static noise and the radio sounded almost as if it didn’t have an antenna on it. I checked all antenna connections and ran without the amplifier turned on. I decided to put out a call anyway and a couple of stations came back telling me that the audio was very difficult to understand. I wondered if the internal speech compressor was on – it wasn’t – I took the amplifier out of circuit – still the same problem. Then while checking cables I lost power a couple of times. What’s going on? Have I travelled all this way only to find the radio has major problems? I located the power problem. A new fuse holder which I had installed on a direct lead to the radio from the battery box along with a bad connection to the back of the radio had combined to create this problem. I performed some more moving of cables and unplugging / re-plugging with the hope of at least temporarily fixing the problem. This resulted in the wire inside the new fuse holder breaking off completely – this was not a wire which I had soldered to the fuse holder – it came with it’s leads already attached (not very well it seems!). So now what? I had a small glimmer of hope, among all the things that I had brought, ( most of which I didn’t need to), had I perhaps left the old power lead for the rig in my rucksack??? Yes! Someone is on my side, the lead was there and once plugged in the power was stable again.

So one problem solved but why is there an audio problem on transmit and why is the receive performance so bad? The penny dropped. This rig has three filters a 500Hz one for CW, a 2.4KHz one for SSB and a 6kHz one for AM. It seems these filters are used on both receive and transmit, as when I switched filters (by pressing what I hoped was the right button as the sun was out by now and I could only just see the OLED screen’s lettering), the receiver sprung back to life and when I checked with a couple of SOTA chasers, the audio was now fine as well with or without the amplifier but they preferred the signal with the 70 watts from the amplifier rather than without!

OK, the problems were fixed, but I had lost lots of time in the process. Time to make some contacts! 50 contacts in 35 minutes later, the pile-up had died away. All reports were fine. I think everything is working correctly again. I had no time to try 20 metres as I needed to get packed up and moving to the next summit, Bussen. While packing up I was approached by a visitor who showed some interest and cost me about 20 more minutes that I didn’t need to lose but – so be it. I wasn’t going to be rude and he did seem interested. I gave him a DARC brochure which he then read from cover to cover while having his lunch. Once I had just about everything packed, I realised that I hadn’t taken any of my standard station and antenna photos but I wasn’t going to set-up again just for those photos, so on this summit, you just get to see the area not the station in the slideshow below.

The trip down the track to the car park was quite hurried but as I arrived at the car, I found that I was only about 5 minutes behind schedule on my (very conservative) plan, so perhaps I could make the time up en-route to Bussen which was about an hour’s drive away.

DM/BW-484 Bussen: The trip from Römerstein to Bussen, was thankfully quite straight forward.

I knew it was going to be a “slog” up the road/path from the car park and so removed some items from the backpack – it was still too heavy, however. The tripod and 10m mast, while being a heavy load I can justify as it gives flexibility as to where I can set up my antenna. Indeed this allowed me to pick a point in the park between the church and the castle ruins, quite close to the trig-point stone, so I knew I was correctly located on the summit. The station set-up went quite quickly but then, HORROR of HORRORS – the filter problem was back! The receiver was dead and now, as this was after midday, the OLED display on the X108G was totally unreadable. I ended up laying on the floor with my jacket over my head and the radio, peering as hard as I could to try to make out the writing on the screen. I eventually managed to see what appeared to be “FIL” and pressed the button alongside it to change the filter from 500Hz to 2.3kHz and the radio burst into life again. This is becoming a major problem which I can’t get around by using my remote control Android program PocketRxTx as the Xiegu does not allow filer changes via the CiV command set. After getting home, I found a solution to this particular problem, however. The multi-function microphone has a button to change the filter setting!! Should this problem occur again, I should be able to resolve it using this button. I wish I had known this earlier!

I started operations at Bussen on 40 metres again and found the band now to be very noisy with what sounded like a distant storm creating electrical crashes across the band. I once again found a free frequency and emailed Ian in Australia asking him to listen for me. Unfortunately, once again, this contact wasn’t to be, so I spotted myself on SOTAWatch and started working chasers. There were fewer chasers on this summit, possibly due to the fact that signals would suddenly drop 5 or more S-points in QSB before coming slowly back up again. The 40m band was in a poor state now. Rather than labour the band, I switched the rig and antenna over to 20 metres and worked a few of the stations who couldn’t get through on 40 metres.

As I was thinking of calling it a day with 22 contacts in the log at Bussen a lady walked up and asked me what I was doing. Another 15 minutes conversation and another DARC brochure given out and then it really was time to pack up and head home.

The journey home was two thirds on country roads and was made more interesting in that a B-road on my route had been completely closed for road works and while a diversion was signposted, the GPS-Navi constantly wanted to direct me back to the point where I had been forced to leave the road onto an even smaller one for the diversion. Eventually, I got back to the same B-road only further down its length and the Navi was happy again.

I arrived home at just before 5:30 pm about 30 minutes earlier than my conservative plan, with some repairs and modifications to look into and a lot of log entries to enter into the SOTA database!

DM/BW-078 Römerstein (50 contacts):

DM/BW-484 Bussen (22 contacts):

Conclusions:

  • The weather was wonderful for a change!
  • The amount of “reserve” equipment that I took AND carried up to the summit and did not need – was far greater than I should have had.
  • I am happy that I DID leave one power cable in my pack from earlier as it was needed, however.
  • The filter setting changing problem is difficult to resolve when you can’t see the X108G screen (Xiegu do not support changing filter settings via CiV commands, so I cant add this function to the PocketRxTX) – however … what I have realised after returning home, is that the multi-function microphone has the ability to change filter settings! In fact, perhaps it’s the microphone that is causing the incorrect setting in the first place by the small button being caught perhaps?
  • The repaired linked-dipole works fine however after adding the 1:1 balun the feed point feels more fragile than the old one that I have used for years. Maybe I should go back to the old – no-Balun solution or find some way to strengthen this feed-point.?
  • I knew that the steep climb up to Bussen is unavoidable but I may return to my longer (but not so steep) access route to Römerstein tower the next time that I activate there.
  • My new lightweight headphones simply work and are comfortable.
  • I had planned to try out the speech processors internal & external but after the other problems, I left well alone as I would have been even later leaving Römerstein and most chasers are not interested in such tests in any case – I was very happy with the help that I DID get in locating the bad audio being the filter problem.
  • The bands were not conducive to DX contacts, so despite my hope that I might get a contact with Ian VK3YFD – it was not to be, despite the amplifier working correctly this time (bias issue corrected).

73 ’til the next summit.

DD5LP/P – May 8th 2019 – DL/AM-180 Berndorfer Buchet.

Preparation:

With the mobility restrictions from the COVID-19 pandemic lock-down being lifted to days earlier, this was my first chance to get out onto a SOTA summit again.

On the 7th. I had worked Ron, ZL4RMF from his superstation in Dunedin from my home QTH at 05:20 UTC and so I sent him an email asking if he might be on the following day about the same time (long path time for New Zealand to Europe contacts) and he kindly said he would be happy to listen out for me. Given the early time, I needed a close summit and Berndorfer Buchet is my closest summit and while only one point, I hadn’t actually activated it this year as yet.

During the lock-down, I had investigated why I was getting RF into the audio of my portable rig (the Xiegu X108G) when using it with my portable 70w RF amplifier. I tried everything to screen all inputs but in the end, it turned out not to be RF ingress (although it sounded like that). The problem was in fact that the Chinese amplifier module that I had set-up exactly to the provided instructions was not running in class AB1 as it was supposed to be but when in use was going into class B or even class C amplification which of course distorts badly an SSB signal!

The problem was found, corrected and then tested firstly local into a dummy load and then via a WebSDR in the days before this activation, so the activation would be the proof of whether indeed now everything was OK.

Berndorfer Buchet is just 30 minutes drive away from home but to make sure I would not be too late for the possibly ZL contact, everything was packed into the car, the night before – including a spare antenna and small tripod.

So the equipment to be used would be the Xiegu X108G, the 70w portable amplifier, the 10m mast and surveyors tripod to support it plus I would also take a new external speech processor to test out if I had time, alongside the built-in one. As always the rucksack had the linked dipole and the 40m OCF antenna (just in case). The extra antenna and tripod I mentioned above are the Konumica HF-Pro2 loaded vertical and a photo tripod, which stays in the new rucksack in any case. Given that Berndorfer Buchet has a forest on top of it, having to revert to using a vertical antenna would be a last resort.

So all packed for what should be an easy activation with the small chance of a nice contact to Ron in New Zealand again.

The Activation:

The trip across to Burndorfer Buchet went without any problems and I arrived at the parking area about 10 minutes ahead of my schedule. Ten minutes that I would need later.

The walk from the road up the forest track while a little cool is nice in the morning. A small deer ran across about 10 metres in front of me – no fear, that is simply the way it goes to get to its feeding area or whatever. The last part of the climb and often covered in leaves and twigs that are easy to fall through, but this time a large forestry vehicle had been part of the way up the slope and made a really muddy mess, that I had to work my way around with my new “Mountaintop” rucksack on my back (appropriate name HI) and the large surveyor’s tripod with the 10m fibreglass mast packed inside it over one shoulder.

Suffice to say when I got to the summit, I was somewhat out of breath! After a slug of water and a quick check around, I started by putting the tripod and thee mast up ready to take the antenna. Then out came the thick green plastic sheet and all of the equipment including the linked-dipole antenna which I intended to use. On taking it out of its plastic bag, I got an unfortunate surprise. One complete leg of the antenna was no longer attached to the feed-point. I considered whether I could somehow work out a way to fasten it together but as the antenna wire also forms the guy rope for the mast, I decided that might not be such a good idea. I always have a second antenna with me and I’m not talking about the loaded vertical HF-Pro2 – I had left that in the car as it would not have radiated with all the trees soaking up the radiation. I’m talking about the Aerial-51 404-UL off centre fed dipole. This antenna has the advantage that it will work on multiple bands without having to be taken down. It has the disadvantage of having to have a 4:1 balun which is additional weight at the top of the mast. In any case, I was glad I had the antenna in the rucksack and that became the antenna for this 40-metre activation.

Once I had all the equipment connected up and turned ion, I started tuning around 40 metres as Ron had told me around what frequencies he normally tried to operate on. The band was electrically noisy, which is strange as there are no buildings anywhere near this summit – so the interference was coming down from the Ionosphere. The signals that I could hear on the band (and there were lots of those) were varying dramatically with QSB. I was starting to doubt whether I would manage any contact with Ron from my portable set-up. In any case, I wanted to try out the amplifier, so rather than immediately calling for SOTA, I went and did some search and pounce but wasn’t able to get any contacts so I put up a spot and called for SOTA contacts. My first reply now was not a SOTA chaser at all – it was Peter G8HBS who had simply heard me calling CQ and called me. We exchanged similar 55 / 56 reports and then I moved on and Terry from York G0VWP called me and again we exchanged similar reports, this time 57 both ways. No one was complaining about my signal being distorted, all was OK with the amplifier – that’s one item off the to-do list completed. I then had a call from Leonardo in Italy IW0QO and this time the signals were not balanced with me giving Leonardo a 59 and getting just a 52 – but that’s OK, the Italians tend to run LOTS of power.

As the SOTA contacts dried up, I went hunting for Ron again and came across a UK station who was also looking for him while talking to some other UK station – so I knew that conditions were perhaps not good enough yet for New Zealand or perhaps simply not good enough, full stop. While tuning around I came across Peter near Belfast in Northern Ireland MI0AIH and had a bit of a chat with him and then tested how well he could hear me without the amplifier so I went down from 70w and turned up the Xiegu to its maximum 20w. result? Peter could hear I was there without the amplifier but could no longer understand what I was saying because of QRM. With the amplifier on, we exchanged 59/57 reports.

By this time I had just about given up on getting any contact with Ron when  I came across that UK station – Rob, M0KPD/M who had been looking for Ron as well. When he finished talking with Per DK7LJ I gave him a call to ask if he had found Ron ZL4RMF. Instead of Rob coming back to me, Per did and once he recognised my callsign, he said that he had worked Ron and Ron had been looking for me. Per checked and indeed Ron was still listening on frequency and Ron and I managed a contact. Not nearly as good as from my home station the day before but despite conditions being worse we did manage a 54 / 45 contact – so the contact was made. When Ron had to go, I carried on talking with Per in Keil in North Germany and he has TWO 40 metre capable beams – one with 3 elements on 40m and one with 4 elements – unreal! No wonder he can get through to Ron in New Zealand on most days!!

The short activation ended very nicely in the end. I didn’t manage to test the speech processors but that’s now something for the next activation.

  • Xiegu X108G.
  • Battery box (2 x 5000maH hardcase LIPOs).
  • SOTABeams linked dipole and Aerial-51 404-UL OCF dipole.

  • 10 metre DX-Wire fibreglass portable mast.
  • Thick plastic painters sheet.
  • Smartphone PocketRxTx App and USB cable.

Log:

Conclusions:

The portable amplifier is working well. When I dropped it off-line as a test with the station in Northern Ireland he noticed a difference immediately. I “guesstimate” 2-S-points improvement using the amplifier over the 20w from the X108G on its own.

My very quick test with the internal speech compressor proved nothing and I need to test how this should be set (and whether the external DYC-817 is any better) on an activation where I am not in a rush to pack up and leave. as was the case on Berndorfer Buchet as we had a short family outing planned for 10am.

The fact that the linked-dipole broke as I was taking it out of its bag was just unlucky and in the meantime, it is repaired and ready for use again.

The contact with Ron in Dunedin, New Zealand is 90% down to his great station and the help from Per DK7LJ letting Ron know that I was there, but contact was made, the radio waves travelled half the way around the world and back again and this on 40 metres at the bottom of the solar cycle!

73 ’til the next Summit!

DD5LP/P – March 20th 2020 – DL/AL-149 Blender & DL/AL-281 Urserberg.

Preparation:

With the likelihood for a mobility ban to slow the spread of the COVID-19 virus imminent, and the weather being still sunny for another day before winter-like weather was forecast to return, I wanted to pack these two summits into the log before the winter bonus points stop at the end of March.

Unlike the last two summits, these two ARE near to each other and easy to navigate between. They are located just outside of Kempten in East Allgau with the first summit, Blender, hosting the TV transmitter tower for the area.

Preparation apart from mapping work (noting junctions to turn on paper) to make sure I took my known route to the summits was to pack the equipment which going to be the same as the previous four summits – the X108G plus the Komunica HF-PRO2  and photo tripod. As that configuration has been working reliably I decided not to pack the surveyor’s tripod and DX-Wire 10m portable mast. Meaning that I am now down to just one rucksack to carry to the summit. It’s still about 17 kilos though, so some more work is required to reduce this down for future usage. When I intend trying for specific DX locations, the heavier, larger kit will be needed but for the current summits, where I just want to bag a few European contacts, this simplified set-up seems to be working well.

The Activation:

When I woke, it was a little overcast to start with but would turn into another nice morning. I casually loaded the Rucksack and HF-Pro2 in its tube into the car and was on the road around 9am. I had no rush to get to the summits, knowing as it got closer to midday it would get warmer and be more pleasant to operate. Both of these summits are “relatively” easy summits although the walk from the car is about 10 minutes in both cases, with the first summit needing a somewhat steep climb however compared to summits earlier in the week, these are easy to get to.

DL/AL-149 Blender: When approaching blender by the road a good tip is to look out for the VW sales garage in Wegschiedel and turn right there, and not take the earlier right turn from the ST2376 road and end up in the wrong place as I did this time! I only lost a couple of minutes though and as soon as I saw the VW garage, I remembered, that’s where I should turn. Although marked as locals-only, access to a hotel along the same road is allowed and hence public usage is not forbidden. Turn left in Eschachberg (the road up to the Blender TV tower) and I park at the point where the road goes off to the hotel and walk from there as there is enough space by the bench seat without impacting access on the road.

From the parking spot simply head up the road and field towards the transmitter tower. Any of this area is well within the AZ but going off to the left and through the turnstile, there is a nice area with another seat and flat area to set-up the antenna.

As the seat was taken up by two cyclists I simply set up on a plastic sheet on the ground and out up the Komunica HF-PRO2, photo-tripod and radial wires and fired up the rig – plenty of noise and stations on the band, so no re-occurrence of the fauöltx antenna cable issue of a few activations ago (I replaced the short length of coax that comes from the rig out of the rucksack, so it would be strange if the new cable was also faulty).

After trying a couple of frequencies, I found a usable one, self-spotted and settled back to pulling 25 stations out of the pile-up. There was a little QSB but apart from that, this operation went quite well.

Once the flow of calls dried up, I packed everything back into the rucksack and headed back down the hill to the car.

DL/AL-281 Urserberg: The trip from Blender to Urserberg is fairly straight forward. Drive back to the main road and at the VW garage, turn left and then take the small road which is the next right and signposted to Eschachreid. In Eschachreid at the T-junction turn right and follow the OA20 road through Eschach and up to the car park for the local lake, the “Eschacher Weiher”. From the end of the car park, there is a farm road which goes up the hill to Urserberg. A point of reference is the tops of the ski-lifts as Urserberg is above those. To be really accurate, the very summit lies within the forest on the top of this hill, however, the grassy area in front of it is within the Activation Zone (AZ) and far more practical to set up a vertical antenna on, rather than within the forest.

I was surprised to find the car park quite full (usually there is one abandoned car and my car in it) and cars were also parked alongside the road (outside of the car park). I presume all the locals were taking advantage of the nice day and heading down to the beach at the lake.

I could see some darker clouds heading my way, so I decided to get up to the summit and get the activation completed before the sun went in. The walk up the road is quite long but the views on the way up are also quite awe-inspiring. Despite the sunshine, there was still some snow at the side of the road as I walked up. Beware of mountain bikers on this road, it appears to be a favourite route for them and they come down the road at quite a speed.

Once I got to the corner before the start of the forest, I went through the open gap in the fence and up into the grassed area. This is obviously a farmers field however there are several tracks across it, and in winter it is most likely a skiing area, so as there are no signs to say otherwise, I believe it to be public access.

After setting up the gear, which is happening quicker and quicker as I have my routine sorted out, I soon had my rucksack with radio and battery box still inside and Android phone display and control on top of it and the HF-PRO2 antenna set up on its tripod and I was ready to operate.

All went well with stronger signals on this summit than the last one but also with deeper QSB making a couple of contacts difficult but in general, a relaxed activation – that was until I saw the farmer coming up the hill will his tractor with the tank and muck-spreader attachment heading up the road. He was going to come into the field but when he saw me, he turned and started with a lower field but I could see he wanted to do the whole area, so I tried to get the calls finished and the station shut-down but more and more chasers kept calling. Eventually, I managed to get a gap when there were no more callers and started packing everything up. As I got finished and started to walk down from my operating position, I saw the farmer coming back up with a refilled tank of slurry and heading to where I had been, so I had cleared just in time. Add to that time limit that those clouds had arrived and covered the sun so it had got clod quite quickly. On arriving back at the car in the car park, I turned the radio on and heard live, the surprise announcement from the Bavarian prime minister, that a lock-down was going to be put in place from Midnight. So I had got my last two activations for a while in, just in time!

DL/AL-281 Urserberg:

Conclusions:

  • The weather was wonderful – the timing just right!
  • The “rapid deployment” (lighter) kit continues to work well but I do still need to remove some weight and possibly also locate the rig better so that the loudspeaker is not obstructed.
  • The two climbs still had me pausing for breath but with the views, it was worth the effort.
  • I had planned to try out the speech processor on Urserberg however the approaching farmer with muck-spreader meant that I decided to leave that for another day (perhaps I can try it out from home while under the “lock-down” order?).

73 ’til the next summit – whenever that may be!

DD5LP/P – March 18th 2020 – DL/AL-170 Zwieselberg & DL/AL-172 Senkelelkopf.

Preparation:

These two activations were originally planned to be part of my activation two days earlier as they are in the general same area as Falkenstein and Zwolferkopf however they would have been too much and so got left.

With the continuing good weather and increasing threat of a lock-in (where no-one would be allowed to leave their homes) because of the Coronavirus, I decided to go and complete these two summits which are located close to each other. Well, that needs some qualification – they are close “as the crow flies” but getting between them via road is more difficult!

One part of my preparation was to see if I could find a shorter route between them to save me some time. I gave Google Maps™ the task and it came back with a route using farm roads, which as I was to find out later, were only legally accessible by farm or forestry traffic. I had suspected this might be the case and in the event had the car’s Navi pre-programmed for it to take me the long way around using normal roads. It’s an interesting area with small villages or actually hamlets, hidden away down small roads in the hills and valleys and what looks like a wonderful lake to go to one summers day some time to enjoy nature.

In any case, preparation apart from the mapping work was to pack the same equipment as for the previous summits – the X108G plus the Komunica HF-PRO2  and photo tripod plus I also packed the two dipoles and the surveyors tripod and DX-Wire 10m portable mast just in case I decided the effort was worth carrying the extra weight to put up a more effective antenna.

The Activation:

I woke to another nice looking day, loaded the gear into the car and was on the road before 9am. I had deliberately not started too early as these are “relatively” easy summits and as the day goes on the temperatures would rise. I was not looking for any DX  stations and as it turned out propagation was poor. This time I was not plagued with closed roads on the journey down and I deliberately avoided the closed road I knew about on the way back.

DL/AL-170 Zwieselberg: It always seems a little bit strange driving to my parking spot for Zweiselberg as the group of houses there have declared independence from the local government authorities (see the first picture in slideshow below). Also, I have to drive up through what is a farmyard between the houses, however, as the sign says, private road use at your own risk, rather than no entry, all seems legal to use it and I have never had any problems. One should watch out for kids who are often playing there though.

After parking in the car park on a bit of a slope, putting the hand brake fully on, leaving the car in gear and putting something under the rear wheel (yes it was that steep a spot). I unpacked the new rucksack containing the radio gear, put the tube containing the Komunica HF-PRO2 antenna on the side of the rucksack and decided to leave the heavy tripod and mast in the car. At this point, you can see how steep the track is and the particular problem here is that the track has been covered with stones to help keep it stable for the farmer’s tractor in winter but for a walker, the stones can easily slip away from you under-foot. Hence the long, steep climb with a heavy rucksack on my back was taken slowly with lots of stops to catch my breath and take some photos of the amazing views. As I approach the holy cross near the summit trig point stone the hut that I remember being there, now has a nice garden with some outside cooking facility added, so it looks like the locals may come up here for their parties.

The cross itself is in a fenced-in enclosure with a long bench and an information table. I set up the antenna at one end of the bench and the rig, in the rucksack on the bench. With my first contact, I was informed that my audio had a problem and it was most likely because of this closeness I think (after all I was standing on the radial wires!). In any case, after moving the radio and battery box a little further away from the antenna, it seems things were fine again.

The views were wonderful from Zweiselberg and  I would have quite happily simply sat there in the sunshine for a couple of hours, but I was there to qualify the summit, so I’d better get three more contacts into the log. I ended up with 24 contacts in the log before the pile-up came to an end.

Time to pack up and head back down the track to the car and then head off to Senkelekopf, the next summit. After packing the gear into the car I got out the instructions from Google Maps and set off following those instructions but also with the car’s Navi turned on. It wasn’t long until I came to where I was supposed to turn off according to Google – while one could have driven a car down the road, there was a sign stating (as I had expected) that “normal” motor vehicles were not supposed to use the road, only farm or forestry traffic. So I gave up on the instructions printed out from Google Maps and concentrated on following the directions given by the ladies voice in the cars Navigation system. It took over 20 minutes to get to the same car parking spot near a small chapel in Oberlangegg that I  remember from the last time I activated this summit.

DL/AL-172 Senkelekopf: From the rough ground where I park my car, it’s a short walk across to the chapel building and from there one follows first the fence up the side of the field to the stile and then the slopes become clear where the tracks go, always heading upwards and a little to the right and eventually you come to what appears to be a farm building (called Senekle Alpe on maps) and alongside it on a small hill to the left is a holy cross, but it is fenced in so that you can’t get to it. Heading off past the building,  to the right, the ground rises up to Senkelekopf where I set up my station. This last rise is less than 25 vertical metres so you could set up anywhere on the flatter ground and still be within the activation zone.

Before I started operating from here, it was time for lunch and a chance to sit in the sunshine and admire the views! I was really enjoying these two activations. The climbs at Zweiselberg and Senkelekopf are strenuous but it’s worth it.

This Summit bagged 25 contacts in all. All on 40m SSB and without a re-occurrence of the bad audio problem as on this summit I made sure to not set up on top of the antenna!

Conclusions:

  • The weather was wonderful again! – I can get used to this!
  • The “rapid deployment” (lighter) kit appears to work well apart from when I set up too close to the antenna. It’s not as “light” as it needs to be though!
  • The two steep climbs exhausted me but the summits were worth the effort.
  • It still had some issues with some SOTA chasers being over-eager but nothing like the problems, two days earlier.
  • I would have liked to have tried out the speech processor (which I had with me) but with the RF feedback happening on Zweiselberg, I decided better of it and just concentrated on getting the two activations into the log.

73 ’til the next summit!

DD5LP/P – March 16th 2020 – DL/AL-167 Falkenstein & DL/AL-166 Zwolferkopf.

A day of blockages, diversions and re-routing – but at least it was warm & sunny!

Preparation:

This activation was originally planned to cover 4 summits, the two 4-pointers listed in the title plus two other 2 pointers that were not too far away. Even at the planning stage, this looked like it may not be possible time-wise as access to Falkenstein and Zwolferkopf is via a single track road with sheer drops at the side which only opens in each direction at certain times to avoid traffic meeting each other with possible “unfortunate consequences”. I, therefore, changed my alerts the day prior to the activations to indicate that I was concentrating on the first two activations and one of the other two would only be attempted should I be well advanced time-wise from the first activations. This turned out not to be the case and that third alert got deleted from the second summit as it was not going to happen (it’s nice to be able to edit and delete alerts via the SOTLAS website now).

Falkenstein has limited space to set up an antenna and Zwolferkopf is a long steep walk from the road, so in both cases, I decided I would use my “rapid deployment” set-up using the loaded mobile whip antenna rather than taking a mast and wire dipole. While I was still thinking of activating the third summit, that one would have had the mast and dipole set-up, so that was also packed into the car.

In any case, a reasonably early start was planned and all equipment charged up ready to go on Sunday evening.

The Activation:

I woke to a nice looking day, (for a change). The gear was loaded into the car with two jackets, one for rain and cold and one for a warmer day. The trip down to Pfronten, where Falkstein is located above is about an hour and 10 minutes trip normally. However … at about halfway, there was a diversion because the road was closed, taking me way off my expected route and to make it worse as I approached Pfronten at the round-a-bout on the outskirts of the town, there was a barrier across my normal exit but with a sign saying that the road was open up until Meilingen, which is where I needed to turn off to head up the road to the castle ruins in any case. So for a change, I was lucky. I even arrived at the start of the single track road, while it was still in the phase for people to drive up the road!

DL/AL-167 Falkenstein: After parking in the car park at the top of the road I packed everything I needed into my new rucksack, including the Komunica HF-PRO-2 antenna in its protective tube on the side of the rucksack and set off up the road. At Falkenstein, there are car parks for the general public and for those staying at the hotel on the summit. The public car park is about 50 vertical metres below the hotel, so there is quite a walk up to the hotel entrance and then from there up to the castle ruins is probably another 70 vertical metres up a lot of uneven steps. On arriving at the ruins, the metal gate needs to be opened and then it’s up two sets of stairs in the wooden platform where I was glad to find that the small round table was still there.

This was the first time in a while that I had such nice weather on a  summit – as I hope the pictures show. After setting-up the photo-tripod, I re-assembled the vertical antenna from its three pieces and screwed it onto the tripod and last of all fitted the 8 radial wires to the bottom of the antenna socket. I have listed on the transport tube which I made for this antenna, the setting on the coil-slider for various bands  (15 for 40  metres for example) so I set the coil slider at 15 and went back to the table where I had my rucksack laid on. Opening the bottom section of the rucksack I have the rig, the battery box, the microphone, the smartphone which acts as the rigs display and control panel and a new coax antenna lead (this is a replacement for the one which created me problems on my last two outings) which the coax lead from the tripod was then connected to.

On turn on, I found lots of stations booming in. I searched for a free frequency but after not getting a reply to my question “is this frequency free”, spotting myself and calling CQ, I heard a station booming in, only 1 or 2 kHz away, making the frequency unusable. This happened time and again on both summits and on the second summit, I had at least one station deliberately causing QRM on my frequency – where is the mentality in that? In any case, once I got on a semi-free frequency the contacts came rolling in and I ended up with over 20 stations for this first summit in the log and it was now time to look at heading for the second summit. Remember that the single track road is open in one direction at a time so I had to get back to the car before the full hour to be able to drive down the road to the spot that I wanted to park at before setting off on the about 2-kilometre track to Zwolferkopf from about halfway down the road. Well again, it worked out well with me with everything packed in the car in the car park ready for the traffic light to turn green from red.

DL/AL-166 Zwolferkopf: On arriving at the start of the track which is about half the way down the single track road I found a place to park which was not too muddy and did not cause any obstruction, locked up the car and set off again with the loaded rucksack up the track. This is a summit where some care is needed. In places, it is not clear where the track goes but thankfully every so often you see there red/white/red mark on a tree or rock, to let you know you are on the track. We are following track E4 here but apart from the start at the roadside, the track number is not indicated en-route. So some fitness is definitely needed as well as no fear of heights as the track weaves it’s way first up the side of the ridge and then along the top of it. This time there was an added complication. From the high winds, we had about two weeks earlier several very large and tall trees had been ripped out by their routes and were blocking the track making it impassible in about four places. This meant some off-track excursions down and around the bottom of the tree or at least to a point where it is possible to climb over the tree or trees blocking the way. With a fairly heavy backpack – I estimate between 15 and 17 kilos – this made the journey “interesting” and longer than expected. When I eventually arrived at Zwolferkopf, which used to carry two SOTA IDs as it sits exactly on the German / Austrian border, it was time to have lunch. The views in the sunlight from this summit are also amazing

As I mentioned earlier, I seem to have been plagued by stations causing me  QRM and this summit is where I had one deliberately causing QRM by running a carrier for minutes on what had been a free frequency (In had checked and called) – there are some strange people in the hobby these days! I managed to copy some chasers through the carrier but after a while, I had to try to find a different frequency and it was on the third frequency that I had QSYed to that I eventually got the calls rolling into the log. I could have, of course just logged the first four contacts and then packed up but I realise that for many chasers this could be a new summit for them as it’s not activated that often. Most likely because of the problems of getting up that track. That being said, while I was there a young guy came up to the summit on a mountain bike! How on earth did he get that past the trees with the bike?

I had just one technical problem on this activation – when I put my hand near to the microphone socket while transmitting, the receiver started making strange noises. I presume this was RF feedback as I had experienced with the amplifier previously but at the moment, I did not have the amplifier installed!

Once I finished and packed up the antenna, tripod etc. into the rucksack, it was time to head down and try to get to the car at the right time to be able to drive down the hill. With no traffic lights visible where I had parked, it would be a matter of checking the clock. Quarter past to 5minutes to the next hour has cars coming up the road and from the full hour for 10 minutes has cars going down to the valley.

I thought as I had found my way around, over, under or through the fallen trees on my way up the track to the summit, it would be straight forward to reverse the process on the way back. It wasn’t and at one particular point where several trees were blocking the track, I was guessing as to how to get around the obstacle. Unfortunately, a couple who had been in front of me were now out of sight so I couldn’t see how they had got past the obstacle. My attempts at getting around the trees took me further and further down the side of the ridge with what felt just like leaves and branches and leaves underfoot. Eventually, I got past the bottom of where the trees were (this was definitely not the route I had taken on the way up the track!) and rather risk heading further down the side of the ridge to come out at a place I would not recognise, I clambered back up the ridge to the track, so that I could follow that back to my car. A lot of effort with the heavy rucksack!

It all worked out though, but through the lost time getting pat the fallen trees, I had missed the narrow, downhill time window for the road, so rather than wait, parked where I was, I decided to drive back up to Falkenstein and wait in that car park which has the traffic light and in fact went and sat in the park nearby in the warm (20 degrees C) sunshine and caught up with my emails until it was time to be able to head down the road again, this time all the way to the bottom.

Knowing my preferred route home had the blocked road, I took a different route home as recommended by my car Navi which took about 5 minutes less than my normal route.

All in all a successful day out. good radio, good exercise and sunshine!

Conclusions:

  • The weather was wonderful for a change!
  • The “rapid deployment” (lighter) kit appears to work well with just the one RF feedback issue appearing.
  • I was right to drop the other two summits, I was exhausted after the problems getting back to the car from Zwolferkopf.
  • It seems the un-healthy amateurs from 80m have moved down to 40m so next time, I may try activating just using 20m if the MUF is high enough. This should allow me still to get the needed 4 contacts to claim the points for the summit (and the winter bonus points at the moment).
  • I would have liked to have tried out the speech processor (which I had with me) but with all the DQRM going on, I wouldn’t have been able to make any reliable tests.

73 ’til the next summit!

DD5LP/P – March 13th 2020 – DL/BE-093 Buchberg.

Preparation:

I had written out a list of simple summits that still have winter bonus points and grouped them together. As the weather forecast was for some occasional light rain but otherwise OK, I decided after my activation of Laber on Wednesday to activate both DL/BE-093 Buchberg and DL/MF-082 Schwarzer Berg as they are not too far apart and both are summits I have already activated in 2019 and access is fairly straight forward. These activations were in principal “points grab”  activations with the period when winter bonus points drawing ever closer.

As it turned out because of the unexpectedly severe weather that I hit on the first summit, I never got to the second one.

I had checked out and re-charged the equipment from the Laber activation and so added the large surveyor’s tripod, the 10 metre mast and my two dipole antenna to the gear to be taken and loaded it all into the car on Thursday evening as I was planning an 0830 (local time) departure for Friday.

The Activation:

 When I set off from home it was raining, but not too bad and after about 20 minutes driving it stopped…. until I approached the town of Bad Tölz, that the summit “Buchberg” where I was heading for, is close to, then the rain started and by the time I got to where I park my car, it was driving snow! I sat for a while wondering what to do. After having driven for an hour, it would be a real waste if I didn’t try to activate. At that point the snow stopped, the skies looked clearer, so I decided to go for it! By the time I reached the summit, it was snowing again (well a mixture of sleet and snow) and the winds started to blow. Oh Great! but I decided to carry on – a quick activation – four contacts, then pack up and head off to the next summit! I put up the mast and dipole wire antenna at less than two metres high – just so it cleared the tripod support and the ends of the dipole were not on the ground. Not ideal but “it’ll do” for getting four European contacts on 40m I think.

Checked a suitable frequency – the band sounded quiet. No response to my question “is the frequency in use” so I self-spotted and called – no response. Tried again – still no response. Tuned around – the band is REALLY quiet. Then I tried moving the antenna cable and … it nearly blew me over. The band noise and stations suddenly were there! The short PL-259 extension cable that I thought I had a problem with on the last activation but could not find a fault when I tested in the workshop was indeed still faulty! I took it out of circuit, pulled the rig half out of the rucksack so that the antenna cable would reach the socket on the rear of the rig and now I could work stations! I searched around and found a frequency where there was a little less splatter-QRM from the other SSB stations on the band, self spotted and called CQ. At last, over 20 minutes after arriving at the summit I got a reply – Andrew G4AFI (who is becoming a welcome entry in the log of late) was followed by 10 other contacts from around Europe in just 5 minutes.

All of this time though, the storm was getting worse and as I kept having to take off my large gloves to operate or enter log data, my hands were losing feeling and when I was finally able to go QRT, I didn’t bother to pack the antenna properly, rather I bundled it as best as was possible into the top of the rucksack. I lowered and packed the mast inside the folded tripod for transport and headed away from the summit and storm as quickly as possible, taking care not to slip over on the now very muddy track on the way back to the car.

I was happy to get back to the car and after a few minutes de-frosting, I considered the situation. Better weather was forecast but could I believe that. The set-up at the second summit would take longer as I would have to un-raffle the antenna, which is a job better done in a warm cellar at home. So I decided to call it a day and leave Schwarzer Berg for another day. On the drive home, the snow and sleet stopped and the sun came out however the winds did not die down, so it would have been a difficult activation at the second summit even if I could get some protection from the winds using the concrete tower there.

Conclusions:

I was unlucky with the weather but I persevered and got the activation in the log. I would have liked to have gone on to the next summit but I was in no conditions to do so.

  • Positives
  • Despite the sudden weather change, I managed the activation and the equipment survived.
  • Operating the radio while still within the new rucksack, controlling via the Android App works well (at least when the android phone is not covered with ice and water!).
  • Ten contacts in five minutes once I had the equipment working was quite a good run-rate.
  • Negatives
  • The faulty coax lead wasted a lot of time – I should have ditched it after the problems on the last activation.
  • Again I did not get time to test the speech processor, which I had with me, but in that weather, it was certainly quite low down my priority list!

73 ’til the next summit!

DD5LP/P – March 11th 2020 – DL/AM-060 Laber.

Preparation:

This activation was in principal a “points grab” with the period when winter bonus points drawing ever closer, but more of a problem, the fact that the cable car that is needed to access the Laber mountain will stop for its annual maintenance on March 23rd so with that date approaching and the weather varying from day to day with high winds being the main concern, I decided to try to get up to Laber on Wednesday 11th and if that wasn’t possible I might include it in a group of summits the following week.

After my problems on the last two activations with the RF from the amplifier getting back into the rig’s audio, I ordered the official interface unit for the rig but as that has to come from China, the amplifier is now out of service for a few weeks and the next few activations will have to make do with 20 watts instead of 70 watts. Laber is a summit with limited space, so I decided to just take my loaded HF whip antenna and small photo-tripod. This configuration does not perform as well as the squid pole and either of my HF dipole antennas but it should be good enough to get me 4 contacts from the top of Laber. Friends in Australia (Ernie VK3DET and Ian VK3YFD) agreed to take a listen for me but with the reduced antenna and the timing (too late for Long path / grey-line), the chances of a DX contact were going to be minimal.

I am still trying to adapt my new rucksack to allow me to operate the rig without taking it out of the rack sack and at the same time, pack all required gear for an activation into just this one bag instead of the two which I normally need to carry.

On Tuesday I did a mock set-up in my cellar of the gear that I would be taking to Laber. This could not operate from underground however it was a check that I had packed everything that would be needed in the new bag. There’s nothing worse than getting to a summit to find you have forgotten one part that is needed to make everything work! An outside test was not possible as it was pouring down with rain and there were high winds – not a good omen for Wednesday!

The Activation:

I woke to a fairly clear morning with some wind but certainly not as bad as the previous day. A quick check of the webcam at Laber and I decided to try. I set off at just after 8 am and the 1-hour drive went without any problems.

I headed out from the cable car’s top station to the actual summit, which is less than 50m away and set up as I usually do on the seat bank under the flag-pole. I set up the photo tripod in the snow behind the seat and then slung out the radial wires in a few directions before attaching the Komunica HF-Pro2 antenna. It was actually pre-adjusted to the right spot on its coil however I moved it to see whether I could hear the difference. Nothing – no change in background noise. I then moved the cable that I have coming out of my rucksack to an SO239 line socket and suddenly the volume of the receiver shot up – so I have an intermittent contact there which I will need to investigate before my next activation.

With the battery box and radio still in the rucksack, all operation is performed using the PocketRxTx Android app on a smartphone, which acts as the display and controls for the rig.

Initially, I wondered if I was getting out or not as after spotting and then calling CQ, I was getting no replies but the delay appears to have been in the spotting system as after a while I got a call from Manuel EA2DT and then a string of calls from around Europe. Eight calls in thirteen minutes. As there were no more calls that I could hear I decided to pack-up with my “mission” completed. It was good that I chose that point to close down as the winds rose and some clouds came in (as can be seen from the webcam shots in the slideshow below).

Overall I was very lucky with the weather as when I arrived home some thousand metres lower, the winds were quite severe, so they would have blown everything away on the summit.

Equipment:

  • Xiegu X108G.

  • Thick green plastic painters sheet.
  • Smartphone with PocketRxTx App and USB cable acting as an external display to the rig.

Log:

Conclusions:

I was lucky with the weather but at the moment I have to “chance it” as it is so variable and the forecasts continue to be unreliable.

  • Positives
  • The new voltage regulator circuit in the battery box performed without any issues.
  • The HF-PRO2 antenna and small tripod is hardly a very good antenna system but given the summit, it’s a good combination to get contacts from around Europe.
  • Operating the radio while still within the new rucksack, controlling via the Android App works well.
  • No RF Ingres problems as I did not have the amplifier with me.
  • Negatives
  • No DX calls but given the timing, this was to be expected.
  • The antenna cable extension needs attention but as this was the first time that it has been used, I was lucky that it was only an intermittent problem not a permanent one.
  • I did not get time to test the speech processor, which I had with me, but it was more important to get back down the mountain before the winds got too bad!.

73 ’til the next summit!
