DD5LP/P – March 4th 2020 – DL/AM-178 Ammerleite & DL/AM-177 Kirnberg.

Preparation:

This activation was originally planned for February 25th however after arriving at Kirnberg the winds got up to somewhere near to 100 km/h, bent the mast over horizontal and blew the antenna feed-point off the top of the tipped-over mast. At this point I decided, the risk wasn’t worth continuing and packed up and returned home.

With the forecast for only light winds, no rain and some sunshine, March 4th. was the first opportunity to try these summits again.

The plan was to activate these two summits plus Laber DL/AM-060 – making three in all, so an early start was planned and the gear loaded into the car the night before.

Each summit was to have different requirements. The first Ammerleite has a nice fence where it is easy to fasten the 6m mast to and run the antenna coax back to one of the two seating banks there. So this summit would have the rig, amplifier and 6-metre mast. Kirnberg, on the other hand, has no simple mast support so for this summit, I packed my ex-surveyors tripod (in which I store my 10 metre mast) – again the plan was to use the X108G Xiegu rig and my 70w amplifier also at Kirnberg. Laber was to be the only summit where I would have snow to deal with being almost twice the height of the other two summits. Access to Laber is limited and has a very small cable car system, where my surveyors’ tripod would probably not have been welcomed as the cable car can get busy at times. Although I have managed to operate using the 6-metre mast and dipole here previously, this was intended to be a short activation and hence limited equipment for some contacts around Europe should be sufficient. So for Laber, the plan was to use my “small” kit of just the X108G, my Komunica HF-Pro2 loaded mobile whip and a photo tripod.

So the rear of the car was filled with all the various components so that when I got to the parking spots below the summits, I would choose what was needed and only take that up to the summit.

Since the last activation, I had changed from my diode matrix to reduce the voltage of the 4S (16v) LIPO battery down to an acceptable voltage for the rig, to using a proper voltage regulator. This would be it’s first real test. I had also modified the PTT switch cable between the amplifier and the rig to hopefully stop the RF getting into the audio input to the tranciever when on transmit that I had previously experienced.

The Activation:

I woke to a clear if cold morning at the home QTH but at least, there were no winds. The roads down to my first summit were reasonably clear and I found my way back to the place I park my car fine. I had realised while on the way, that I had forgotten to pack my light “inner gloves” but as the forecast was that the day would warm-up, I thought nothing more of this.

DL/AM-178 Ammerleite: The approach to the Schnalz (the real name of the summit, Ammerleite is the name of the area) became more and more muddy, not surprising after a week of rain nearly every day. It remained cold and the winds started – looking around there were some very black clouds heading my way, so I’d better hurry this activation along. I had hoped to catch an NZ or AUS chaser via grey-line propagation but it was not to be, not so much because of propagation but rather because of my delay in getting the station operational.

After putting the mast and linked-dipole antenna up and connecting the rig with the amplifier to the antenna, there were loads of stations coming in on 40m. I spotted myself and put out a CQ call – no takers. I tried calling some of the very strong stations on the band – no response or in one case a response but he said I was too weak to copy. What? 70 watts from the top of a mountain, he’s well over S9 and can’t copy me – that’s strange. I decided then to try 20m but again with no takers. At that point I got an email from Ernie VK3DET who had been listening for me, saying he had heard absolutely nothing on either band. I came to the conclusion that either the rig or amplifier were not putting out any power or that the antenna was broken in some way.  I had an RF sensor with me and that showed output from the amplifier so it had to be the antenna. Luckily I always carry a spare and took down the SOTABeams Band hopper and put up my Aerial-51 404-UL OCF dipole instead.

I then tried calling a very strong signal from a mobile station on Sardinia – he came back to me but said that I had distorted audio which made it difficult to understand me (remember I said, I had hoped I had cured this high power RF signals getting into the audio stages problem – it looks like I haven’t). When I switched off the amplifier and turned the rig up from 3 watts to 20w – he said all was fine. This was about an hour after I had arrived on the summit and was now far too late to hope for any DX via the long path. I decided to get another three or four contacts in the log and then pack-up as by this time I was VERY cold. I wish I had gone back earlier for the inner gloves as for some of the intricate actions, I had to take my large gloves off and my hands got quickly very cold. Many of these actions would have been possible with the thin inner gloves on. There was a sort of light sleet that had come through, not enough to make you wet but certainly enough to make you even colder. I was now running behind schedule and so decided I would pack-up and head to my next summit. At that point I got about another 8 stations call me on 40m all with good reports for my signal. Now I started to wonder whether the first antenna may have been fine but the problem was the RF getting into the transmitted audio however I’m pretty sure that I had tried with and without the amplifier to rule out an amplifier switching problem. In any case, the OCF antenna would get used on the next summit and the linked dipole checked once I got home.

As I was so cold, on the way back down the summit to the car I was wondering whether to head home rather than to the next summit, however after a warm drink and something to eat in the car, I decided to at least do a short activation of Kirnberg and then see about Laber.

DL/AM-177 Kirnberg: As I thought the linked dipole had broken at Ammerleite, the configuration for this summit was to be the surveyors’ tripod with my 10 metre mast (only at about 4 m high as it turned out), the Aerial-51 OCF dipole and the rig (with no amplifier because of the RF getting into the transmitted audio problems). This meant I only had one bag instead of the usual two plus the large tripod and mast. The short climb up to the cross on Kirnberg was very slippery, again not surprising considering the weather we have been having. Soon after arriving the winds started to increase and the farmer, on whose land the cross is, came by collecting blown down tree branches. I went and had a quick word with him just to check I was not in the way. No problems – we had met a year before and he has no issues with Radio Hams setting up and operating near the cross. If I remember correctly from last year, this farmer had been in the communications corps of the German army and so has an idea of what I was doing and was interested. This time though he wanted to get on and do as much as possible as he, like I, thought this would be the one day of the week when the weather was not too bad.

Thankfully this activation didn’t hit the technical problems that I had on the first summit and I could get a few stations on 40m and 20m into the log. By this time there were also a few other activators out and I tried for some S2S contacts but unfortunately, other chasers kept transmitting on top of my call and no one told the other activator that they had an S2S calling. The longer I was on Kirnberg, the stronger the winds were getting, so the forecast of it getting better (warmer) during the day and there being no winds was totally wrong again! Having got about a dozen stations in the log, I decided to call it a day and as I was taking the mast down, the winds increased drastically. That was my decision made. If the cable car at Laber was running at all, it would not be a nice ride and going onto the summit in these winds would not be the most sensible thing to do, so I decided to scratch Laber from this trip and hopefully get back to it before the winter bonus points stop or it’s cable car closes for maintenance.

Conclusions:

  • The weather again was not what was predicted but at this time of year, I have to grab whatever day looks like it might be OK!
  • The new voltage regulator in my battery box worked well giving no problems and not getting hot as my old diode matrix did.
  • Since getting home, I have checked the linked dipole and have found no definite problems with it. DC continuity and solder joints on the feed-point appear OK, so perhaps the problem was the RF getting into the audio – I was putting out a signal but people couldn’t understand what I was saying perhaps? I will need to test the antenna again. As regards the RF Ingres, I have ordered the official interface split-out board from China which claims to totally isolate all lines from each other. Until that arrives I won’t be running the amplifier.
  • I still have my new dynamic speech compressor to test, however trying that while I had other problems would not have been a good idea.

73 ’til the next summit!

DD5LP/P – March 12th 2019 – DL/AM-177 Kirnberg & DL/AM-178 Ammerleite.

Preparation:

With constant bad weather from the start of March I wanted to get out and grab some Winter bonus points and at the same time make sure all equipment was working, before I was to meet up with Brian VK3BCM from Australia and take him to some SOTA summits. The previous week, I had travelled out to DL/AM-177 Kirnberg only to be forced to pack up after having got the antenna up, due to the high speed and bitterly cold winds. I had alerted for these summits a couple of days earlier but again with the weather had to postpone them.

I was now determined to get these activations in as this day was forecast to be somewhat better (not that weather forecasts are to be trusted nowadays) In any case everything was put ready for an early start as the wife needed the car in the afternoon.

I decided to concentrate on the tried and tested equipment, no testing any new equipment.

The Activation (Kirnberg):

As I approached Kirnberg, things looked fine (but they had done also the last time I was here). It was somewhat more muddy than last time as there had been heavy rain storms in the last few days.

I grabbed the surveyors tripod, one of my 6 metre masts and my usual two bags (one with the radio, battery box and headphones and one with the antennas and other small items in) and headed up the hill to the cross and bench on the summit.

All started well and the tripod allowed me to position the mast where I could run out the linked dipole easily in both directions. One end got tied off to the bottom of the concrete cross (I know not perhaps the best option but it’s there and would not be damaged by the cord) The other end ran down and was pegged into the ground.

At this point the winds started – this summit seems always to be windy and cold! Well I quickly set everything else up and got on the air. 20 metres was totally dead and 40 metres not much better but I managed nine contacts in 25 minutes and while I needed to get the second summit in as well, I called it a day at this point, packed up and carried everything back down to the car and set off for Ammerleite, on the other side of the valley.

The Activation (Ammerleite):

The run to where I park my car for Ammerleite took about 20 minutes and this time, I decided not to take the tripod as I knew there were convenient fence posts that could support the mast and the ends of the linked dipole. So there was less to carry this time, thankfully.

Set-up again on one of the two benches at this “Schnalz” summit and with the X108G connected to the smart phone so that I could see the display in what was now becoming a sunny day, and somewhat warmer than at Kirnberg, I was set to go. I didn’t even try 20 metres this time and concentrated on what was now a much better 40 metres. Signals were stronger with less QSB than at the previous summit.

Starting at 11:10 local (10:10 UTC) I managed twenty contacts in twelve minutes! This is how the activations used to be! There were no DX contacts in the log however even though I did listen specifically for Ernie VK3DET with whom I had a sched hoping to manage a 40 metre short path contact as had been possible in previous weeks at around this time. Today this wasn’t to be though. Rather than continue trying and while the chaser calls had dried up, I decided to pack everything up and head home so that the wife could have the car a little earlier than promised.

Conclusions:

The propagation again wasn’t great but at least I managed to get two more “easy” summits off my list for the winter bonus activation points. The equipment worked reliably meaning once I recharged the battery, everything would be ready for the follow days planned three activations with Brian VK3BCM.

All in all a good activation after the failed attempt a week earlier. The sunshine and little or no wind on the second summit was a pleasant change.

The sudden high SWR indications occurred with this (known good) antenna as I had seen with the VP2E antenna on the previous activation, so I believe this is false data being sent from the X108G to the smart phone App (PocketRxTx) rather than there being a bad SWR occurring.

73 ’til the next Summit!

DD5LP/P – February 5th. 2018 5 summits in a day DL/AL-169 & 179, DL/AM-001,176 & 177.

Preparation:

As it’s now a new year and we still have the winter bonus of three extra points to the activator in force, I decided to put together the well tried and tested gear and head off to five local, easy access summits. Originally I had though of including a sixth – DL/AM-178 Ammerleite however since the easy access road has been made private, there is a long walk of about 2 kilometres from another road and the last part of that route is not on a prepared track, rather across a field up to the summit cross. this last part can be problemsome. I have been up to my knees in snow on this last part of the ascent and even if the snow has cleared the ground will almost certainly be very muddy. Not a good candidate for a “quick” activation.

Equipment would be the “tried and tested” Yaesu FT-817ND plus modified Ramsey HF amplifier, the SotaBeams band-hopper linked dipole and my 6 metre fishing pole plus this time a screw-in Sun umbrella base.

The Locations:

Auerberg is accessed from the church and restaurant’s car park and then a walk of about 50 metres up the side of the church (quite a steep climb but not long). Around the back of the church this is a bench seat to sit on and fence posts to attach the antenna mast to.
Weichberg is accessed from a forest car park and then walking up through the forest about 150 metres to the Chapel with table and bench seats outside.
Rentschen is a drive up summit formed by a plateau. Once there I walk across to the trig-point stone and set up. No bench at this one, take something to sit on.
Kirnberg has no car park so I drive to the farmers gate and then walk up alongside his fence to the cross (this farmer is really cool, he towed me out when I got bogged once – typical country guy). There’s a bench at the cross here as well.
(Hoehen-)Peissenberg is the easiest of all, you drive to the car park and then walk up the concrete steps and path to the other side of the church and set up on the bench there.

My plan was to activate DL/AL-169 Auerberg, DL/AL-179 Weichberg, DL/AM-176 Rentschen, DL/AM-177 Kirnberg and DL/AM-001 Peissenberg in that order. The order seemed reasonable however as I later found out, it would have made more sense to reverse the first two as the route from DL/AL-179 to DL/AM-176 took me back through the village underneath DL/AL-169. Oh well, next time I should know better. In the same way the route from Auerberg to Weichberg could be along main roads but leaving my GPS Navi to do the route planning it took me along single track country roads, in at least two places these went THROUGH farm yards on their route! Oh the fun of GPS-Navis!

The Activations:

The weather at home although cold there was no snow to be seen. Surprise, surprise all summits were still snow covered from snow that came down a couple of weeks ago! Temperatures varied from -9C on Auerberg “up” to -4.5C on the last summit Peissenberg. I was glad of taking my thick winter jacket but despite that, the way I felt when I arrived home, I believe I suffered some Hypothermia.

Apart from the realisation that I should have done the first two summits in the opposite order, the drives to the summits were uneventful.

Auerberg (my first summit) has a surprise for me when I arrived apart from the horribly cold temperature (-9°C) access to the summit had been closed as renovation work on the church building that sits on the actual summit has started and everything was fenced off. At this summit, even down to the car park is part of the Activation Zone so I set up on the short track up to the church. Of course now I had no bench seat, so I put out my painters sheet which kept sliding down the slope on top of the hard packed but also frosty snow. This was not starting off the day well! After spotting and calling for some time I did manage to get 5 contacts despite at one point, my smart phone being so cold that it stopped working actually “froze up” and then rebooted. This was cold. So as soon as I didn’t hear any more calls I packed everything up and headed back to the warmth of the car. Even folding the painters sheet was difficult in the cold and several items simply got pushed untidily into the rucksack.

After a scenic run along single lane country roads, I got to Weichberg. While there was still the bench seats and table here, a small tree that I used to strap the antenna mast to was no longer there and I had to use a fence post some distance further away. The end result was that the coax from the antenna was not long enough, so I had to put the station on the painters sheet on the ground again. That new antenna location can’t be very good as I had difficulty getting contacts just managing the minimum four required before packing up. Even though the temperature had now risen to -6°C the small rubber reels that I wind the antenna leads onto was really stiff and that combined with the, mandatory in these temperatures, gloves meant winding up the antenna took longer than normal. Everything takes longer than planned in such cold temperatures. To add to the fun, the antenna wire broke when I was taking it down and so got a quick repair so that it could be used on the next summit.

It was while driving to Rentschen, I realised that I was driving back past Auerberg and could have activated the two Algaeu summits in the reverse order. Apart from that the drive was uneventful. On arriving at Rentschen I decided to park just half off the road to avoid getting bogged, took the usual two packs plus my sun umbrella screw-in base as I knew at this location, there is no where to strap the mast to. I set up about half way between the road and the trig point stone (the whole plateau here is in the activation zone). By now the temperature had risen to -5°C and a lot more chasers were active. I managed 15 contacts on this summit in 12 minutes and then started the pack-up again. While I could have tried 20 metres for more contacts, I was already running late on my planned schedule, so I only operated 40m SSB on each summit.

The next summit about 30 minutes drive away was Kirnberg and I here I left the car parked on the road (I learnt my lesson getting bogged once before here). The wind had increased and the temperature had fallen one degree down to -6 again. Once I walked up to the summit cross and put the gear on the bench seat, I again used the screw-in base to support the mast. I have strapped it in the past to the fence posts but it has often tilted over a lot, so while I had the base with me, I decided to use that. This summit brought me eight contacts in five minutes before I packed everything up again and headed back down to the car. Just one more summit to go.

The drive over to Peissenberg was probably the longest and went past the point where I would have turned off to do Ammerleite but the overall direction was heading towards my home now. I grabbed a little lunch (I had brought a pack-up with me) before setting up at my normal spot on the bench overlooking the valley from the side of the church. This time 15 minutes brought 12 contacts and an interested visitor who I talked to for five minutes. Now that I had enough contacts on 40m, any thoughts of perhaps activating 20m were curtailed by the fact that my Smart Phone (which had been running 4G comms for watching and spotting all day and Bluetooth for hands-free while in the car) had 100% drained its battery. Without being able to self spot, no one would know that I was on 20m looking for contacts. So it was definitely time to pack up and while packing away one of the link connectors in the antenna broke away from the wire  – another thing to fix at home (along with the broken wire, which was now wound together and taped). Peissenberg was a “warm” -4.5°C by the time I left for the well used by me, country back roads route to my home.

I was surprised by the fact that there was still snow on these low summits (at home it had melted 10 days earlier) and especially the wind that I found made the low temperatures even worse. It took longer than normal to get anything done.

I am glad I didn’t try for the sixth summit, it could have ended with me being very ill by the end of the day. Do not under-estimate the effect of cold on the human body.

I decided to stay with the same equipment on each summit. Had I used my Aerial-51 OCF dipole instead of the SOTABeams band hopper, I could have switched to 20m without having to take the aerial down but it probably was wise to stay just on 40 metres when I had limited time available for each summit.

73 ’til the next Summit!
