DD5LP/P – April 30th 2024 HEMA DL/HBY-064 & SOTA DL/AM-180 Berndorfer Buchet.

Posted on by

Preparation:

My closest summit is Berndorfer Buchet and as I needed a summit I know to test my latest build of the 2-element HF wire beam, this one pointer was ideal as I had not yet activated it in 2024.

This was the first dry day in about a week and as more rain was expected later in the week, this was to be a quick activation. Just enough time to set up the beam, test it on the analyser and bag a few contacts ideally on 20 and 10 metres.

A relatively late activation was planned, to arrive at the summit by 9 am local (0700 UTC) but despite this the complete station fitted into/onto my 40L backpack would be loaded into the car, Monday evening, the night before to allow an easy departure the next morning.

The Activation

DL/HBY-064 / DL/AM-180 Berndorfer Buchet

As normal I woke 30 minutes before my alarm went off and was all packed and out of the door at 7:30 am as planned for a 9 am (0700 UTC) start. I had hoped to fill the car at a garage on the way but there were so many queued that I decided to leave it for the return journey.

Although sunny, it was still cool. Walking from the parking spot to the open area 15m below the summit, the track was muddy and I hoped that the small area where I intended to set up was not as much of a bog as it was the last time I used it.

Although soft underfoot, the ground had dried enough from the last few days of rain to be usable. After putting down my painter’s sheet, I proceeded to unpack everything from the rucksack. A more complex operation than normal with the HF beam antenna rather than just a dipole or loaded vertical.  Once the mast and antenna were up and the elements/guy ropes positioned, my first task was to run my RigExpert antenna analyser on the beam with it switched to each of its four directions, as while, I had only moved the complete feedpoint electronics from a flat board into a box, there are several things that could have gone wrong. I had done DC connectivity checking but this was the first chance to test the antenna completely.

The first trace (see photos) for the beam on 20 metres (it covers 20 & 10m) with it pointed West, was a little strange with two dips shown. These were OK if a little strange. I then pressed the key fob to turn the antenna to the North and ran another scan – see next photo – this was all over the place. It was worse still when I wanted to clear the trace and try again, the RigExpert analyser would not let me. I tried turning it off – nothing! the trace stayed. Unplugged the coax, no change, so there was nothing for it, but to take the back off and remove the batteries, which I did and I was able to turn the unit on again, but as soon as I tried to take a trace again (this time with the antenna switched back to the known good West direction) the same mess on the screen and the unit had hung up. Luckily I have seen this before – these units don’t like low battery voltage and after once again removing and replacing the batteries, I could see on the startup display that the batteries were low. So, as I had no spare batteries with me I put the analyser away and continued to set up the radio, hoping that the antenna was OK.

Well, the first station in the log was Ernie VK3DET with a 5-5 in both directions, so I guess the antenna was working. Band conditions were all over the place though. Some DX stations (VK4 and Jamaica were booming in while others from Finland were not as strong as usual – with the beam switched north). Ernie reported having just worked some portable stations in the UK with S9+ signals and had expected me to be stronger but 20 metres was in such a mess that in the 10 minutes in between signals had dramatically changed.

After spotting myself on the SOTA cluster I tried calling CQ for 10 minutes on 10 metres with no responders. All I could hear was the local 10m beacon about 25 km to my south – I used this to check the antennas directivity and as before I got 2 S-points less signal off the back and 1 S-point less off the sides. That said, this was not a complete test for the antenna and I will need to plan to go out again and check it with the analyser again, now that it is working fine with some new batteries.

20m had really deep QSB but at least the weather stayed fine long enough for me to complete the activation.

Conclusions:

  • You can never predict what will happen. Thankfully the crazy readings from the RigExpert were caused indeed only because of flat batteries.

  • The band conditions were disappointing overall compared to activations a couple of weeks earlier.

DD5LP/P – For World HEMA Day – September 1st & 2nd 2023 – DL/HBY-064 Berndorfer Buchet & DL/HBY-038 Staufenberg.

Posted on by

Preparation:

The idea of World HEMA Day is to get as many HEMA activators out as possible to try for H2H contacts. With the recent expansion of HEMA into Malaysia (West & East) and Canada as well as across Europe, with good propagation and good timing, someone may manage some good DX H2H contacts. For me with the times I could get out, my target was around Europe but as you’ll read surprisingly there was some DX around (if chaser stations, not activator ones).

My original plan was to activate two summits on Friday afternoon and one on Saturday but when the one on Saturday became difficult to reach as roads were closed for re-surfacing and I decided on a different summit, this became a possibility for a “family day out” with my wife and dog. Seeing some countryside that we have never been to, having a nice outing in the good weather and topping it off with a nice meal at a country restaurant.

So with that extra work on Saturday, I decided to keep the Friday activation down to my most local HEMA summit and as it turned out that was a good decision with additional road-closed delays affecting that activation.

As I will be heading to Cyprus in just over a week, for a week (including some radio activations), these two activations were also to serve as equipment tests. The first just using my normal radio station in a 40L rucksack set-up and the second trying to operate with a smaller (5 metre) mast and a smaller ground peg.

The Activation

Friday 1st September 2023 DL/HBY-064 Berndorfer Buchet

The usually simple drive to this HEMA/SOTA summit was complicated by a main road being closed the day before. While there was an alternate route, the fact the normal route was closed was not shown on the road until after I got past the exit for that other route. Indeed I only knew that I could not turn right as normal in Fischen until I got to the roadworks themselves. I had to turn around a head back about 3 kilometres to the alternate exit – this added about 20-25 minutes to what is normally a 35-40 minute run. Luckily I had set off early and was able to be set up on the summit to activate as planned for the start of “World HEMA Day” which ran from 1200 UTC (2 pm local time) on Friday, September 1st to 1200 UTC on Saturday, September 2nd.

The activation brought in contacts from around Europe. I started on 40m and there were several strong Italian stations on the band to start with then I suspect the critical frequency rose over 7 MHz as propagation became very NVIS-like and the second part of the hour that I activated was almost all stations from within Germany. It was a pleasant time chatting with other amateurs but as I had alerted to operate on 20m as well, after about an hour I decided to move to that band and re-spot myself using the new “HEMA Assistant” Smartphone app. This app appeared to be very slow in refreshing its list of spotted stations but even with the slow response (which wasn’t a problem on Saturday. It was some kind of temporary problem – possibly with my internet access from the summit). The app did show however that I was the only HEMA activator out at the time I was on my summit. Among the 40m contacts I did have a summit-to-summit contact however and that was with Ben DL2DXA on GMA Summit DA/SX-224 near Dresden.

After switching to 20m and hitting the tune button on the radio, the Linked dipole which would normally tune straight away was causing issues. I lowered the mast again and found that the 17m link had come open. Looking at this, I could see that the wires were taught and the solder joints were looking a little “aged” so one maintenance task when I got home was to adjust where all wires were tied into the links and to resolder all joints to the 2mm power connectors which I use for these links. This was exactly the kind of thing that I wanted to find before my trip to Cyprus.

Back to 20m – after reconnecting the 17m link and raising the 6 metre mast again. the G90 tuned the antenna quickly – actually with this (resonant) antenna I could turn the internal tuner off but it does help to spot these kinds of problems. I decided to tune around on 20m and while there was not a lot of activity – this was about 13:15 UTC, I came across Tony VK5KI on Kangaroo Island in South Australia working an XE station (who I could not hear) – unfortunately I waited too long to call Tony as I wasn’t sure when the other station signed off. Tony was about an S7 so a contact might have been possible. I suspect Tony may have been going QRT in any case as it would have been approaching midnight with him.

Further searching on 20m brought some Eastern European stations in a net but apart from that the band was very quiet, so I found a free frequency and spotted myself both on HEMA and on the DX Cluster. Unfortunately about a quarter of an hour of CQing brought no responses. As it now started to get colder and there was a possibility of showers forecast, I decided to call it a day, knowing my home route would be slightly longer given the road closure, so that was my first activation for World HEMA Day completed.     

Saturday 2nd September DL/HBY-038 Staufenberg

I had planned the summit Rentschen (DL/HBY-052), which is a 45 minute’s drive to my south for my Saturday summit but for that one, I was forewarned of the road closure and so for an extra 5-minute drive, this time north from where I live, I decided to do the first activation of Staufenberg (DL/HBY-038). This is a literal drive-up summit (as is Rentschen) and for anyone looking for a really easy summit to activate in a beautiful country area, this might be a good choice.

We set off at 9 a.m. only to hear that part of our route on the Autobahn was down to one lane from three following an accident and to expect a delay of at least 20 minutes filtering through the one, still open lane. So, we told our GPS to seek a different route and we went cross country. Unfortunately, this route was to cost me. While going through the industrial outskirts of a town with minimal traffic  I sped up to get through some lights before they changed only to find a speed camera waiting to trap people on the other side just before the speed limit increased from 50 to 60 km/h – flash … I now wait to see what the financial damage will be!

Soon after I had set up the station, the air-raid sirens went off in the area for about 10 minutes. As this was at exactly 10:30 a.m. local time, I presume it was a test of the emergency alarm system in the area and not that my mighty 20W of RF had triggered some alarm HI.

As well as the normal equipment in the car, for this activation I had brought along my 5-metre squid pole, which will be light to carry for the Cyprus trip. Along with that, I intended to use the decathlon base spike to support the base and the normal sun Umbrella screw-in base is not practical for the trip. The first obvious limitation was that the thin 5-metre pole was very loose in the base but after searching around for some cord in my rucksack, this limitation was addressed and the cord is now packed within the base so that it stays with it. I was of course unable to use the top section of the pole so the antenna’s feedpoint was at around 4m AGL meaning that the end cords needed to go out a fair distance and that the 40 metre end sections of the linked dipole were quite close to the ground. Use of this antenna with with my 60 or 80m extensions would not work with such a low mast however as I rarely use those bands that is not such a great loss.  

Once the antenna was set up in the grassed area alongside the small chapel on this summit, the radio was unpacked and set up on my normal plastic sheet and I was ready to start on 40m to see who I could find. 

Before spotting I took a tune around and found Peter in Dusseldorf with a strong signal calling CQ and getting no replies despite his special event callsign of DQ23IVG for the Invicta games being run in Dusseldorf this year. (The Invicta games are for injured soldiers – from any nation – to compete in sport despite their injuries and form part of their recovery and return to as normal a life as possible). 

Next, I checked the HEMA Assistant app (which worked with little delay on this activation) to see that Dave G8XDD was out on the G/HSE-019 HEMA summit in the UK. After a couple of tries, I managed to break into his pile-up and got the first H2H into the log.

I then found a clear frequency and spotted myself via the app. 40m was terrible with QRM from multiple contests that were in progress (which is the main reason I rarely activate on a Saturday). There were callers but they were crushed by splatter from the station who started up a kc or so away from the frequency I was using without checking first. Bad operating? Yes, but these are crocodile contesters – most don’t listen for stations under an S9 signal level – perhaps their radios aren’t capable of it from all the stray RF coming back into the front end from their own linear amplifiers? As I have said before there are good contesters but unfortunately they are the exception, the majority don’t care about other spectrum users.

After fighting to get contacts on 40m I decided to move to 20 metres to try my luck there. At this point I found another advantage of the lower mast – I was able to un-clip the 20m links in the antenna without lowering the mast. while this is just a small point it does make the operation simpler. Once on 20m, I wished I had moved there earlier. The contesters had not yet arrived in their hoards and the band was relatively quiet, enabling me to find a good frequency, spot myself on HEMA and start calling CQ.

The first station who called was Uwe as IK7/DF3DAD a solid 59 signal from Ginosa down in the “heel of the Italian boot”. Following Uwe was Don G0RQL from Cornwall England who had tried on 40m but on 20m this was a 59/58 easy contact.

There then followed a nice stream of chasers from Poland and the UK. One Karl 2E0FEH told me he had just worked a HEMA activator, Bill M0DXT, but he was not spotted on the HEMA list so Karl agreed to do that. Of course, Bill was back on the QRM-band 40m but I would try after all the aim of World HEMA Day was to get as many H2H contacts as possible. As soon as I announced that I was moving to 40m of course I got more calls on 20m, so with those logged and happy, I then switched back over to 40m to go and hunt Bill. Again the lower antenna meant a quick change of bands was possible and I found Bill on the frequency that Karl had told me he was on but unfortunately, two Italian stations were also having a long chat on the same frequency – I suspect neither Bill in the UK nor the two Italians could hear each other but unfortunately with me being in the middle I could hear both. In any case, I battled on and in the gaps in the Italian’s transmissions, I managed to get the H2H contact in with Bill M0DXTT on G/HLD-043 for my second WHD H2H contact.

All of this time my wife had been walking the dog along several of the clearly marked walking tracks that go off from the summit and I decided that after an hour of operation, it was time to pack up and head off to the beer garden restaurant in the Bonstetten village for lunch.

This had been ideal activating weather and the sunshine through the trees and some very good food for a reasonable price in the beer garden just made it a perfect day – well actually only half a day as it was altogether a 4-hour round trip. None of us were eager to do too much more however when we got home. Some good weather, fresh air and good food made this an ideal day for all three of us!

Conclusions:

  • Let’s hope that more HEMA H2H contacts were made on Saturday. On Friday, I was the only HEMA Spotted station on! The problem on Saturday was as always, the contest stations.
  • The equipment tested on the Friday activation had me repairing and adjusting the linked dipole so that the links no longer jump out. The smaller mast and mast base tested on the Saturday activation worked fine and in fact with the antenna wire a little lower I was able to switch between 40m and 20m without lowering the mast, however, this set-up will not let me use the 60 or 80m extensions to the antenna. 

73 ’til the next summit(s).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DD5LP/P – June 18 2023 – HEMA DL/HBY-064 & SOTA DL/AM-180 Berndorfer Buchet.

Posted on by

Preparation:

Fresh back from my trip to Austria, it looked like John VK6NU was going out while on holiday in Ireland to an EI SOTA summit. Mike (2E0YYY) would also head out to give John a call and to round it off if we both could get to our summits early enough Ernie VK3DET had offered to try for a contact. So a contact with either John or Mike would be both an H2S and S2S contact as my chosen summit is in both schemes.

The set-up would be the tried and tested G90 plus Linked dipole and the 6m mast, all of which pack into, or onto my medium-sized rucksack. However, after struggling with carrying the rucksack over the last few days, I decided to try something different and bought a shopping trolley with fairly large wheels from the local Aldi store for €30. when the shopping bag is removed my 40-litre rucksack sits perfectly on the frame and is held there using the existing straps and clips on the rucksack.

As the Long path window to VK had been opening earlier over the last few days, this was going to be an early start to be on air by 0630 UTC – meaning I needed to set the alarm for 0630 local time (0430 UTC) to get up, drive to the parking area, walk with the (as yet untested) trolley to the summit and set-up the gear ready for operation.

 The Activation

Berndorfer Buchet – HEMA DL/HBY-064 and SOTA DL/AM-180.

This is my closest summit and it took just over 30 minutes to get to the car parking area early in the morning.

Once parked, it was a single action to take the rucksack on the trolley out of the rear of the car, so that saved a couple of minutes. I set off, half expecting to have a problem with the trolley before I got to the summit and then I would need to stop and “de-strap” the rucksack from the trolley and carry it for the rest of the distance. Luckily this did not happen and the trolley served me well, even when “bush-bashing” up the last (steepest) part of the access, where no clear path is available, there is high grass with nettles and thistles in it and the ground is covered with dead twigs and leaves.  

When reaching the summit, I was able to leave the masts in the side of the rucksack, strapped to the trolley, get the linked dipole out of the top of the rucksack, unpack it and thread it onto the top of the mast, run the wires out to roughly where I thought I would be tieing them off on trees and then raise the mast to its full height. This is an improvement on the usual process of screwing the sun umbrella base into the ground, adding the mast and so on.

After also taking my thick painter’s sheet out of the top of the rucksack, I opened up the front of the pack to take out the radio and battery. This whole process worked very well and overall saved me at least 5 minutes, possibly 10.

Once I was set up, I sent Mike 2E0YYY/P a message via the “signal” messaging app (this summit has a good cellphone and hence Internet coverage) to find his frequency. A couple of minutes later we had a contact, weaker than usual but good. At this point Ernie, VK3DET tried to listen for me and gave me a call. Although I could just hear Ernie, it was difficult and again a lot weaker signal than expected. It was no surprise (given the power difference) that he could not hear me. That’s the way the bands are sometimes – however, looking into this later I think I know the reason why;    

MUF during the activation – this explains some of the QSB and other problems on 20m (remember as a general rule, you will get the best DX conditions on the highest band under the MUF line). In short, 17m and even 15m might have been a better choice rather than 20m:

Being a weekend, there was of course the hassle of wide splattering contest stations (and wanna-bees) so finding a free frequency was especially hard on 40 metres but in the end, I got a few contacts in the log from around Europe as you will see from the logs below.

After packing up, thankfully, the route back to the car with the trolley was no more difficult than on the way up.

Conclusions:

  • Weather conditions in Ireland meant that John VK6NU never got properly on the air before having to head back down ahead of the storm front.
  • Band conditions were variable on 20m and 40m was almost unusable because of contests that were going on, leaving hardly any free frequencies to operate on.
  • The equipment all worked as it should. The trolley helped with getting the heavy rucksack along the tracks however did have some problems as I went “Bush-hacking” up the final 25 vertical metres of ascent through grass, thistles and fallen twigs on a layer of old leaves. It performed wonderfully, however, as the base support for the antenna once I got to the summit. So “the jury is out” as to whether using the trolley is better than carrying the rucksack on my back. It may be better for some summits than others. It would be easier to pull if the handle was a little higher, so maybe some modifications will happen to the trolley over the next few activations.

73 ’til the next summit.
