DD5LP/P – October 22nd 2016 DL/AM-001 Pießenberg for VK-EU SOTA S2S event.

Preparation:

The planned EU-VK S2S SOTA event was set for Saturday October 22nd, here’s my piece on ARNewsline:

“You don’t need power when you have altitude”

October 22nd. 2016 will see an increase in Summits on the Air activity between Europe and Australasia.
As has been the case for the last few years, a special event is being organised by Andrew VK1AD and Mike 2E0YYY to coincide with the improving radio propagation conditions.

 

 This “S2S” (Summit to Summit) ‘all mode’ CW, SSB, Data, and even FM, event already has commitments from VK, ZL, G, GM, DL, and OE stations with other European stations expected to join in the climb to the top of mountains in each region. These “activators” aim to make as many “S2S” contacts as possible with other hams on SOTA summits in Europe and Australasia.

The timing will be from 06:30 UTC for about two hours and is planned to coincide with long path propagation between Europe and “down under.” Around the same time, short path communications between Europe and North America is often possible. So if some SOTA activators in North America could listen out from a SOTA summit, this activity has the chance to create a World-Wide Summit to Summit event this year.

Most stations will be running low power with simple omni-directional antennas, so this event also aims to show just what can be achieved with limited equipment from a location with a low noise floor.

Although I had originally planned to use my new EFHW vertical on the 10m mast, at the last minute I decided it was better to go with the tried and tested linked dipole as risk the antenna collapsing on me again. I need to build some more confidence in the new antenna/mast before it can be used reliably. In fact I plan to create a lightweight version of the antenna using RG-174 co-ax in place of the RG-58 reducing its weight considerably.

Equipment would therefore be the 817, the 20W amplifier, the 6m mast and the linked dipole antenna.

The Location:

Pießenberg is about 45 minutes drive from where I live and a drive-up summit, making an early start as required for the long path propagation to VK a possible option. There is plenty of parking and a short walk to seating at the far end of the path around the church with railings to attach the mast to. As I have already activated this summit twice this year, I would not get any activator points for this extra activation but it is the most practical for an early morning activation and my S2S points are fast approaching 1000 – perhaps I could break the magic number on this outing? (the answer was NO – not quite).

The Activation:

The trip down to Pießenberg almost was a problem with a major accident closing the main road between Pießenberg and Hohen Pießsenberg where I needed to go. Luckily I was approaching on the back roads and when I was stopped by a young fire brigade officer he said I was fine to get through the village as far as the road up to the summit and take it up to the church.

 While setting up, in the dark, I found a broken link connector on the linked dipole, which would not affect 20 metre operation but would stop me from being able to move to 40m to catch local summits, and what I thought was a broken bongo-strap (turned out it was ok when I could see it in the light later). I was set-up and started operation at 0530 UTC (too early – also too dark and too cold!).

I was happy with one good contact with Jason ZL3JAS in Christchurch at 06:31 UTC. While tuning the band I heard his 5-9 signal, called him and he came back to me, giving me a report of between 4-4 and 5-5 – considering I was running 20 watts to a dipole and he was running 1KW to a cobweb antenna, I’m happy with that report. It seems that the grey line long path window at the moment from ZL to DL is around 0630 UTC. I also bagged 5 x S2S contacts within Continental Europe summits but could not hear the UK activators on 20m.

It was very annoying to find that whichever frequency a VK activator was spotted as being on had either a Russian or Italian 2KW+ station chatting to his mates – how do they manage this? Probably the same way as the Italian and Russian stations would come up on my (checked free before calling) CQ frequency meaning I was constantly having to move. I found out later that my signal was getting through the VK2 but I was not hearing the reply because of this QRM – that’s annoying.

By 0715 UTC I was hearing less on the band and the battery in my amplifier had run flat so I packed up at 07:40. Later I heard that VK6 was coming through at around 0800 UTC but without the amplifier, I suspect my signal would not have made the trip.  I also had a family trip I had to be back for. I’m kicking myself for forgetting the spare battery for the amplifier and for having two conflicting requirements on the same day, but I couldn’t do much about the latter.

Here is my report publshed on ARNewsline and WIA NEWS:

Summits on the air Summit to summit international event 22nd. October 2016.

October 22nd saw the Summits On The Air, Australia to Europe Summit to Summit event. Fifty one summits across Europe, Australia, New Zealand and Japan were registered by their activators as intending to take part in this 2 hour “super-activation”.

When 0630 UTC arrived with weather varying from freezing cold to pouring with rain in Europe and not a lot better in Australia, the SOTA activators started their calls. Between 6:30 and 8:30 UTC seventy three summits were activated – twenty two more than expected.

Mother nature and propagation were “variable” to say the least but contacts were made between continents as well as within each of the regions.

At times the number of active summits made it difficult to find a free frequency on 20 metres to call CQ on.

Thanks to Gerard VK2IO for the following audio clip of my signal making it through the “ether” from Southern Bavaria to New South Wales Australia. Unfortunately no contact was made due to QRM from QRO stations in Europe who often started up transmissions on top of the QRP SOTA stations.

< the audio clip was played here >

The organisers Andrew VK1AD and Mike 2E0YYY declared the event a success and planning is under way for future Australia to Europe SOTA events, most likely twice a year around the dates that we change the clocks in Spring and Autumn.

A similar event is being discussed between European and North American activators. Once details are confirmed, you’ll here about it here on ARNewsline. In the meantime checkout sota.org.uk to find out about Summits on the Air.

For AR Newsline this has been Ed Durrant DD5LP from Bavaria in Southern Germany.

chart-of-stations-taking-partConclusions:

I had a few “OOPS” moments and wrong decisions:

  1. I was on site FAR too early, it was cold (but thankfully there was no rain), dark – I almost needed a torch to set-up but managed without and because I started so early I ran my rig’s (and more importantly, the amp’s) battery down.
  2. Rather than risk the newly built vertical, I decided to go with the tried and tested linked dipole. On putting it up I found one of the link connectors had broken off the wire – not an issue for 20m but this meant I couldn’t switch to 40m to pick up EU S2S contacts.
  3. I forgot to take the spare battery for the amplifier. In fact when I saw the amp was no longer turning on, the Internal LIPO had hit zero percent on all 4 cells. Later I managed to recharge the battery and it “seems” no worse for wear. Time will tell. Normally I avoid taking LIPOs below 25% charge.
  4. Timing – not only was I set up too early, I also shut down too soon (partially due to the amp battery but also as I needed to get home for a family outing). If I had stayed another 30 minutes, I might have bagged John VK6NU in WA.

Even with these errors I managed 5 x S2S contacts but only within Europe. I’m rather proud however that I managed a good contact with Jason ZL3JAS in Christchurch.

What I found REALLY annoying was the fact that I was not able to even listen for spotted VK & ZL SOTA activators as in EVERY case when I went to the spotted frequency a local high powered Russian or Italian station was chatting away to his friend down the road on exactly the frequency the DX SOTA station was spotted on. I also had to move several times when calling CQ when an EU QRO station simply decided they would use the frequency to natter on, without first checking it was free!

73 ’til the next Summit!

DD5LP/P – October 18th. 2016 DL/AL-179 Weichberg.

Preparation:

With the planned EU-VK S2S SOTA event set for Saturday October 22nd, I wanted to test a new antenna that I built from information given on the SOTA reflector. A 20m halfwave, coax fed end-fed vertical. This antenna has no BALUN/UNUN or ACU, it uses a quarter wave stub to match the 2.5K ohm of the end of the half wave to the 50 ohms needed by the rig.coax-efhw-calculatorI tested the antenna on my antenna analyser and was very happy with the results:

The results on the Analyser after building to the dimensions from the spreadsheet –

Resonant frequency 14.285 MHz (as required by me for SSB operation),
SWR 1.42:1
IZI = 52.4 ohms
R = 49.4 ohms
X = -17.4 ohms
C = 634 pf.

Very impressive for an end-fed simply cut and soldered – no trimming at all was necessary!

Now I needed to test the antenna in the real world and decided on an activation of DL/AL-179 Weichberg as I knew I had the choice of vertical supports to strap the 10 metre mini-mast to.

Equipment would be the 817, the amp, the 10m mast and the new antenna.

The Location:

Weichberg is about 45 minutes drive from where I live and as such one of the closest summits to my home. It is only a 1 pointer however relatively easy to get to – about 10 minutes walk up a forest track from where I park the car. Navigate to Rettenbach and then follow the road “Dolce” as far as you are allowed to drive and there is a parking spot for 4 cars and the track to the summit is across the track behind you.

The Activation:

Subtitle – Wet hands make sloppy installations!

The trip down to Weichberg was uneventful except for a diversion through a beautiful small village because one of the main junctions on my route is being repaired/upgraded. The further south I drove, the heavier the rain became, until I turned off the main road onto the small road to Rettenbach when it started to clear. By the time I got to the parking spot it was down to a light drizzle, at this rate this is going to work out! I thought. …

I walked up the track through the forest to the summit and into increasing rain – never mind, I’m here now, let’s get busy! I unloaded my two rucksacks and started attaching the 10m mast to the best vertical post available – the holy cross outside if the small chapel. With hands getting wetter and colder I stretched my first “Double Bongo Strap” around the post and just as I was about to interlock the bongo in the rubber band – “TWANG” – it was gone and no amount of searching would find it! OK, have to make do with just one double Bongo Strap, that went on OK and then I unrolled the 1/2 wave 20m coax fed vertical antenna across the ground, attached it’s crocodile clip to the top section of the mast and started winding the thin wire around the fibreglass pole as I raised it section by section. Slowly but surely the antenna was raised. By this time the rain had become heavy but I thought there’s no point stopping now as I’m soaked anyway. The rain had started coming through the sleeves of my so called waterproof winter jacket.

Once I had the antenna raised, I went back to the small table on this summit where I assembled the FT817 and amplifier, connected batteries and turned everything on. 20m sounded quite busy which was a good sign. I checked 14.285 which appeared free, put out a call to check and then started calling CQ. In parallel I tried to place a spot but with water running over the face of the smart phone, it was difficult to type anything in! Then someone called – QRZ? So I went back a couple of times but the caller said they had too much QRM from a station 2 KHz down so I announced I would QSY up to 14.290, which I did and started calling again. About this time I got the first spot out but the call that came back on 14.290 was from someone who had just heard me calling rather than a SOTA chaser and I had a nice, if short, QSO with Panna from near Athens in Greece. We exchanged 5-9 and 5-5 reports – so the antenna was certainly working.

I started to put out another CQ hoping for a SOTA chaser who would have seen my spot but just at this time there was a loud “CLUNK” behind me and the fibreglass mast had telescoped itself down to ground. This was probably just one junction that I didn’t pull out enough with the cold, wet hands as there was next to no weight on the mast.

I took a look and while the mast and antenna were not broken, the antenna had tied itself in so many knots that it would take me 10 minutes to un-taffle it in good weather with non-frozen hands. As I was finding more areas of my jacket where the, now heavy, rain was coming through, I decided to pull the plug and pack up and head back to the car and its heater to dry me out.

To add insult to injury, by the time I arrived home, the rain had stopped completely but the TV said there are banks of rain storms coming through.

Despite aborting the activation (it counts as an activation as I had one contact, and as activated this summit earlier in 2016, I would not get any activation points in any case if I had “qualified” it with 4 contacts) it was still a useful exercise. I now know the antenna works. I know to take more care “locking” each section of the mast in place. I have already found a replacement “Double Bongo Strap” that was holding some other antenna and it’s coax together. If anyone finds the strap on Weichberg – they’re welcome to it. Who knows perhaps I’ll find it there next year but searching for it longer in the grey, rainy environment today was pointless.

I will take both my usual dipole and this new antenna on Saturday for the VK-EU S2S party. I’ll decide which to use on the day – if Long Path to VK doesn’t look good I’ll need the 40 metre capability of the dipole to contact EU stations but the vertical up first to give it a good “go”.

All parts are currently drying out and I’ll most likely untaffle the antenna while watching the TV this evening!

 One amusing point is that I found the Trig Point stone on this summit as well. In fact there were three stones(see pictures) – the two with metal tops I suspect might be used for mounting the measuring instruments.

Conclusions:

The antenna worked. I would have liked to have more reports from different directions and distances but in the weather, I was glad that I managed the one contact. I know to be mre careful with this mast now, making sure each section “locks-in”. This appears to be more of a problem on the DX-Wire mast than on the cheap “Lambda-Halbe” one!

73 ’til the next Summit!
