Just a little Perseids activity

Only a few QSOs during the Perseids Meteor shower this year, but at least over five times more than last year. πŸ˜€ Kidding aside, just too much QRL again so only QRV every now and then for short time periods. Although most of the stations have been worked before I always enjoy every single MS contact, it really has something special to it!

MM/DH8BQA: 6 m opening from IO75kk

Marc, DO4DXA from JN58, asked during the contest if I could come to 6 m as it was open to Scotland. Did so after the contest was finished and easily worked him on CW with the KX3 matching the ZS6BKW with it’s built-in tuner. 😎 A few more CW-QSOs followed (10 in total) but activity was very limited. I then switched over to the IC-705 again (no noise on 6 m from the USB connection!), put the Elecraft T1 antenna tuner in line and matched the ZS6BKW on 6 m again. Astonishingly it worked quite well! Could then do a few more digital QSOs (15) and even worked DL3BQA and DL3BUA from home! 😎 All very spotty but nice to do some VHF contacts from abroad, too. Finally started disassembling the station after about 14z …

Working digital on 6 m … just 10 watts and an HF dipole!

Contacts worked from IO75kk including two “locals” … can you spot them? πŸ˜‰

MM/DH8BQA: IOTA Test from EU-123, Isle of Arran

Actually, the IOTA contest would have been a non-event for me this year. Since my wife and daughter only got vacation for the last 2 weeks of July, I had already written off the contest in my mind. The plan was a week of holidays in London and then another week with friends in Edinburgh. The return flight would have been right during the contest.

At some point my lovely wife asked if I was aware that the UK was an island and if I could do radio from there? After all, at the end of July there is always this β€œstrange island contest” where I go away. Good wife! πŸ˜€ So we rescheduled a bit and I took the girls to the airport on Friday, then Mr. BQA had time for himself. 😎

Equipment carried along: An Icom IC-705 & Elecraft KX3 with aΒ  ZS6BKW antenna on a 10 m Spiderbeam mast, the small one suitable for flight luggage with a pack size of just 70 cm. The whole stuff with accessories already weighed 15 kg, but it must not be more than 23 kg in total for checked luggage and I also needed some clothes for 2 weeks (don’t ask: the girls’ suitcases were as heavy even without radio equipment, rearranging was no option, hi). So only QRP. Why is that important? Well, if QRP then maybe seriously fight for the trophy which is also available for QRP for UK Islands Expeditions, unclaimed last year. I had selected a few good looking QTHs in Scotland, some of them really nice locations, but it would all have been EU-005 “only”. A quick inquiry to the organizer revealed that I could take part in the DXpedition class, despite EU-005 which is home to thousands of “fixed” stations, if I transported everything there myself. That was a given. After all quite an interesting idea and yes, compliant with the rules. So it would have worked. πŸ˜‰

But: With low power operation the QSO potential is mainly concentrated on Europe anyway. And with only a 10 m high wire as inverted V far away contacts on the low bands would certainly be out of reach, too, but probably quite a lot of UK on 80 & 40 m. But as “same island” stations they would only count 5 points while from another island it would be 15 points! Strategically much smarter! So I researched a bit further (AirBnB is your friend!) and found what I was looking for on the Isle of Arran, EU-123: a small caravan (with a camping toilet and without running water, for the purists, hi), on top of a cliff right on the Sea, clear take-off from north-east over south to west. It should also fit with travelling there (once across Scotland), ferry, the booked return flight, etc. And it did, ufb!

QTH for the weekend in Kildonan

Will have to look up the LH reference πŸ˜‰

Station setup on Friday afternoon went smooth. Weather was fine, mast and antenna went up quickly. Happy camper. 😎 A few transceiver issues though, see below.

Mast and antenna installed Friday afternoon

Ladderline from antenna to transceiver, no coax this time!

It was quite stormy during the night from Friday to Saturday with heavy rain. Hoped the antenna installation would hold up to it but unfortunately it didn’t! Luckily it was an easy fix.

Mast collapsed during storm Friday night, ouch!

All set up again Saturday morning, luckily it was calm through the contest.

GM7M always works the IOTA from Arran, too. According to the last reports and maps on their website I had mentally located them in the middle of the island on top of the mountains. The QRM by them on the low bands was extreme. The KX3 lived up to its name, as a direct mixer it pretty much mixed every signal with that of GM7M. πŸ™

It got cold during the night.

It worked ok’ish when running myself, I could minimize the problem by clever frequency selection. On the high bands it was less bad, but still quite obvious. I had expected more from the KX3, at 15km distance it shouldn’t be an issue at all. The sideband nulling procedure will probably also have to be carried out again.

Sunday morning Zabdi, my landlady, came and said that there were 3 masts like mine at the campsite 600 m down the road, and if that might be radio amateurs like myself, too? As it turned out GM7M with high power was right next door, not even a kilometer away! Wow, then the KX3 did really well in these circumstances! It’s all a question of perspective. πŸ˜€ When I went to the campsite in the evening to take a shower after dismantling the station there were no signs of GM7M anymore, seems they qickly took down everything, too. Pity, could have been another interesting talk. πŸ˜‰

It would have been exciting to see how the 705 would have performed in these conditions. I had tested the setup with a USB cable for rig control at home on a dummy load and configured everything and all worked fine. But then in the field noise with S9 on the HF bands with the USB cable connected?! Damn … The ferrites I brought along didn’t help. Communication via WiFi and/or Bluetooth with the computer is no problem for CAT, audio, etc. I had that configured easily. But CW doesn’t work with it (or I haven’t figured out how yet, if anyone has any tips, I would be grateful). Oh well. πŸ™ Good thing was I had the KX3 as a spare (tnx Heiko, DG1BHA, for the loan, I wasn’t sure if the 705 would be delivered in time for the trip) as I didn’t want to leave anything to chance with the goal of “winning a trophy”. Seems I was perfectly right doing so. πŸ˜‰

Night setup. πŸ˜‰ Caravan was just big enough to keep the station installed. Or was it the transceiver and laptop just small enough? πŸ˜€

Overall I’m very satisfied with the result. Various mults slipped through my fingers due to the QRM issue, so it could have been even a bit better. With QRP as a mult you can also do running which works quite well (though not as well as as a high power station, hi).

At some point on Sunday morning I needed a little break (sleeping, peeing, making coffee … 2 hours).

Condx have been mixed, the start on Saturday was really slow, later things got a little better, high bands only really usable on Sunday thanks to a bit of Sporadic-E, had some decent rates in that time frame. Tnx to all callers!

When handing out number 666 there was still too much contest time left (almost 8 minutes). Thus I continued. πŸ˜‰ At number 670 the net counter stood at 666 and I saved myself the last 50 seconds. πŸ˜‰ Made a handful of SSB QSOs, too (which are in the log, of course, but counted out below), but I entered CW-only. Now let’s see if it was good enough for the trophy. Even if not: great weekend, lot’s of fun, recommended for imitation. πŸ˜‰

MM/DH8BQA: Visiting Jim – GM4FVM in Scotland

Summer time = holiday time! This year the three of us decided to spend a week in London, then move on to Edinburgh for another week together with a few friends making it a group of seven. Had a very enjoyable time although we nailed it with walking a few kilometers through London on the hottest day ever recorded in British weather history! Oh well … πŸ˜‰

When deciding to visit Edinburgh I also looked up a few of the well known VHF DXers in Scotland to see how far they are away. I do like to meet the locals if time permits (which is sometimes rather tricky when travelling in a group). As it turned out Jim, GM4FVM, whom I had already dozens of QSOs with (see QSL below as an example … everybody active on 4 m will certainly have QSO’d him already 😉), is just an hour’s drive away so I asked him if he was okay with a short visit. And he was! 😎

We had a very pleasant afternoon with him and his lovely wife Sue. Thanks for the awesome tea and original scones, very delicious! πŸ˜‰ While the girls had a walk through their fantastic garden exploring all the “green stuff” I’m not as interested in πŸ˜‰ Jim and I, after visiting his small efficient antenna farm, made it to the shack and discussed a lot of things. We are very like-minded on so many topics and interested in the same stuff I often had the feeling I was sitting there with one of my best long-time friends! Really great and after all one of the many things that make Amateur Radio stand out as a hobby: finding friends over the air and maybe even meeting in person like in this case.

Many thanks Jim & Sue for the very enjoyable time! Will sure meet you on the bands again but hope to meet in person in the future again, too, maybe next time in Germany. πŸ˜‰

4 m was open into the South, too, and even opened nicely via double-hop ES to the Canaries with EA8AVI (IL28) and EA8BFK as well as EA8JF (both IL38) making it into the log. Like these 3.500 km+ openings! 😎

Some Tropo for a change!

Sporadic-E, Aurora, now some Tropo for a change! Love the summer month’ as there are so many different possibilities to catch different propagation modes on VHF, it’s just amazing! Certainly one of the reasons why I fell in love with VHF DXing many many years ago. πŸ˜‰

There was some good tropo from Western Central Europe and the U.K. down to Southern France and Spain. We were way too far away from all of it but once in a while signals popped up enabling the following two contacts: 😎

Sporadic-E on 4 m & Aurora on 2 m

Interesting day today! Four was open this morning via ES to the UK & Ireland as well as EA & EA6. It closed at 12z and never opened again, MUF down. Thus nothing to expect on 2 m either, right?

July VHF Contest ’22

July VHF contest is usually the VHF contest I participate as a single operator. Again so this year. Result is on par with those of the last few entries. It’s been a few years since breaking the 400 QSOs barrier from up here.

                 VHFREG1 Summary Sheet

    CallSign Used : DH8BQA

Operator Category : SINGLE-OP
             Band : 2M
            Power : HIGH
       Gridsquare : JO73CE

        Band   Mode  QSOs      Pts   Pt/Q
         144   CW      78    38172   489,4

       Total   Both   366   147767   403,7

            Score : 147.767

              Rig : IC-9700 + PA
         Antennas : 10 ele DK7ZB Yagi

Should be good enough for a Top 3 finish. No specialties, you could call it business as usual. A good number of CW in the mix and almost 100 x OK/OM wkd. Activity in SP was quite good as well (20 stations) and besides the usual 2 x YU I even managed to work a YO again (and two more heard!).

On the other hand just one LY in the log which was disappointing as they normally have their national VHF fieldday that weekend, too, and you can easily work 8-10 stations at least. Not sure why there was nobody on this time, maybe they changed something or even skipped the contest for some political reasons? Who knows.

More ES, even on SSB ;-)

Following yesterday’s openings 2 m was hot again all day long. At times we had two or three different path’ open (Greece, Italy, Spain) in parallel. And there was some good SSB activity, too! Not to miss anything I went SO2R (Single Operator, 2 Radios): while I used my usual remote setup with the Flex plus transverter and SSPA into the 9 ele LFA for digital I also had our IC-9700 with the tube amp into the 10 ele DK7ZB connected for SSB. It certainly paid off! 😎 Not sure about G4LOH. There was some ES around at that time but it might as well have been Ionoscatter.

I entirely concentrated on 2 m so didn’t work much on 4 m. But from the few QSOs made 5B4AIF (KM64) and SV9CJO (KM25) are certainly worth mention. After all the spook was over it openend again late evening to GM with the usual suspects.

Bands hot again

Another great day! Started with a JA opening on 6 m although only 3 stations wkd (all JA8 from QN03/23). Once again I had the feeling being much too weak although running 400 watts into an 8 ele longyagi. πŸ™

4 m opened 8:30z and was open literally all day long into different directions (9A, 9H, G, GM, EA, SV, YO, S5 wkd). Icing on the cake was working IZØAXF/JN61, probably still illegal. Hope Italy will get a permit to operate on 4 m again soon, there are so many potential new squares to be worked. πŸ˜‰ MUF got higher and higher during the day enabling inner-DL contacts on 4 m with as low as 600 km distance to JN48! So it was just a question of time for 2 m to open and it did although we were not well postioned thus all very patchy. But a few good QSOs were made:

Nice openings on 6, 4 & 2 m with new ones

Early start this morning with the first QSO on 4 m at 7:30z into the Balkans. Beaming East 6 m provided interesting QSOs and new squares with UN7DAT/NO00 and RD6AK/KN85. I doubt that the latter is legal but as always: WFWL – work first, worry later. πŸ˜‰

Two opened to Greece around 9:30z and I was very lucky to catch Erwin, DK5EW, on his DXpedition for a rare new square (unfortunately I missed him in the other ones). A bit later we had another brief opening, this time to UA6:

Have been heard in UA3 and IT9, too! While the latter might well have been ES (the band was open to the South) I suppose the first was rather MS.

Carribean on 6 m with ZF1EJ as a new one around 13:30z, plus HI8 (FK58) added to the mix. Some more 4 m in between (EI, GM, OH) and a short 6 m opening to the U.S. around 15:30z providing EN91, FM17, FM19 squares.

First 2 m ES for me this year

Four was open all afternoon. Two opened just briefly over here, good enough to work EA5BY (whom I had just worked on 4 m, too,Β  half an hour ago):

CQ WPX CW ’22

Another WPX-CW is in the books … 10 m of course, what else? πŸ˜‰ Condx worse than during the last few years, just not as much Sporadic-E this time. Thus also not that much DX although we had some multi-hop ES (or maybe ES + F2) to North America Sunday evening. But all very spotty. Else the typical southern path’ which all needed some ES to link in, too.

3D2R – Rotuma as ATNO & a good 6 m opening

Worked DPØGVN, the German Antarctica base station, on 10 m today. Also caught the Rotuma expedition 3D2RRR as an All Time New One on a few HF slots. 6 m opened via multi-hop ES this afternoon, too, providing several stations from 5B4 (KM64/65), 9K2 (LL48/49), A71 (LL55) and HZ (LL25). But the icing on the cake was finally working 7Q7CT (KH66) for a new one! 😎

First 4 m ES opening this year

Seems like a late start on 4 m this year, at least for me. While I usually work the first 4 m Sporadic-E opening early May, sometimes even at the end of April already, it’s been the end of May this year. Band has been open to EA2 (IN82/83) shortly around 18z today.

Midnight Longpath on 10 m

Upper band HF condx have been quite good recently. I was able to catch DPØPOL/mm off the coast of South America on 10 m CW late this afternoon. But the real surprise was seeing a late night long path opening to VK/ZL during the last 1,5 hours (it’s just midnight local time over here), probably enhanced by some Sporadic-E. Great to work a bunch of VKs plus ZL4TT and had a nice chat with VK4DO on SSB with 59 signals both ways. 😎

May VHF & a few NODERED dashboards

Another VHF contest. Again not too motivated to operate but brought the special event call DM60UEA (60 years of Amateur Radio in AngermΓΌnde) onto the air on 2 m & 70 cm. Made about 250 QSOs, people had difficulties with the call even if we were CQing. Oh well …

I spent most of the time not on the radio but rather programming NODERED. I had set up a Raspberry Pi as a NODERED server and now programmed a few dashboards to make it possible to remotely rotate all our antennas just using a web browser. We’ve been able to rotate computer-based using the superb PSTRotator software for over 10 years already. Drawback was: only one connection at a time making coordinating between operators almost impossible and inconvenient (starting/stopping software, trying to avoid blocking each other). Furthermore PSTRotator only works on Windows and my approach to the remote setup is to make it OS independent, i.e. being able to control everything no matter if using a Windows computer, a Mac, a tablet or even a smartphone.

Available stuff from other hams was a useful start (there’s a very active NODERED Ham Radio group on the groups.io forums). I had to reverse engineer a few things as there were no existing flows for our use case (our rotators are network connected and use TCP/IP instead of the more common serial interface for remote control). But after I recognized how all that stuff works it was no problem to implement. Likewise for our NETIO power controllers. I found flows to control the Elecraft KPA500 and KAT500 as well so connected both with their serial interfaces to the RPi, too. The KPA500 flow still has some potential for optimization (a few ideas in my head already, hi) but it will do as is for the moment.

As always lots more ideas for additional stuff, lets see when I’ll have time again to dig a little deeper. πŸ˜‰ Here are a few screenshots of the dashboards available now:

Dashboard for our VHF rotator. As we have a 2 m yagi as well as a 10 m beam on the same mast I implemented two different azimuth maps to make it easier to turn to the right direction. Both are linked, of course. Rotator can be switched on & off from the dashboard and besides remote operation is used from the HF shack now. The rotator is in the VHF shack so no need to change between the rooms to rotate the antenna anymore. πŸ˜‰

Another dashboard for the smaller remote mast with 2 & 4 m antennas.

Dashboard for our AZ/EL rotator (which used to have the antenna group for EME). Besides there are power on/off buttons for a few things accessed remotely.

A combined dashboard for the HF rotators. The right one shows beamwidth as well but currently no rotator connected as we have to repair the control unit. They can be power controlled from the dashboard, too.

My remote dashboard to switch stuff on & off and see what the amp and tuner are doing, here just transmitting on 10 m.

March VHF Contest ’22

This must have been one of our worst March VHF results. πŸ™ Very low activity, bad condx … but still a respectable placement coming in as #7 Multi OP which is not bad for our remote location. Finished a few smaller things around the shack and most important: had fun being together! πŸ˜€
