Conditions up, antennas down

Of course, once conditions improved the winch on my main mast failed. At least it locked up, and stuck in the fully lowered position. It did not freewheel down from the top. For this I am thankful.

Yes, it is mounted that way up for a reason. 

Anyway, I may return to this topic later. For now I wish to deal with the VHF/UHF opening here between 23 and 28 December 2025. The winch failed on 26 December. That was not as bad as it seemed as it only affected my main mast which has the 2m and 6m antennas on it. My 70cm and 23cm antennas were fine and I put them to good use. And I could still use 2m, just with less height and thus with limited effectiveness.

So here are the bare facts about the 6 days in question - 133 QSOs to 13 countries with 56 squares.

A smallish high pressure moved West from the European Continent, joining another high and developing further. It then remained fairly static for several days centered over Britain. As tends to the best case with these things propagation moved along, in this case early on to the East, then sweeping South. The various bands opened in different directions over time.

Contacts were to F (31), DL (28), OZ (20), G (13), SM (13), PA (10), GM (5), ON (5), EI (2), HB9 (2), SP (2), LA (1) and UA2 (1). 

If there seem to be fewer pins than contacts in that combined map that is because several stations contacted me multiple times on different bands and sometimes over different days. For example, six of the French stations accounted for 17 QSOs between them, and four Danish stations accounted for 10 contacts. Three stations were worked on 23cm and 70cm bands, and I had several more attempts to do this but 23cms proved difficult with long slow QSB.

My QSOs were over an average distance of 774km. 

144MHz

Turning to the individual bands, I made 75 contacts on 2m (mostly before the winch failed). Best DX was to Igor, UA2FZ in Kaliningrad, 1437km, on 25 December. I had worked UA2 on 144MHz before, but only by using meteor scatter. As it is theoretically possible to work all over Europe fairly easily by meteor scatter I never credit my contacts using that mode with the same value as other ways of doing it. Over the years I have chased UA2 on Sporadic E without success. To add it finally as a new country by tropo was particularly nice.

Even more pleasant was the way the UA2FZ contact came about. As is often the case during openings, the "Senior Service" of the hobby, those with 1kW linears and 8m long multiple beams, were resting by listening for somebody sufficiently DX-y to stir them to transmit. I, on the other hand, believe that if nobody calls CQ then nobody will ever work anybody. So I persisted in making short calls and Igor duly came back to one of these. If I had waited for DX to come to me then nothing would have happened. Calling CQ too often can be annoying to others, but on the other hand just listening produces nothing.

432MHz

My 150W on this band was proving fairly effective during this lift with 53 contacts. I managed to work a new country on the band when I contacted HB9EFK on 28 December. This came out of the blue and presented me with the best DX on 70cm during this opening at 1315km. Nick has a superb location and should do very well from such an elevated site. Also in the good DX realm was F4IAA near Perigueux, a distance of 1218km. Not shabby at all and we worked twice on 70cm during this opening and tried 23cm too.

Even with those pretty good contacts on 70cm I suppose that I am still disappointed that I am not doing better on this wonderful band. I would like to have a better antenna higher up, but this applies to all bands really. I had some plan to move the 70cm beam on to my main mast, and if I had done that it would have been stuck after the winch failed. That would also come at the price of a longer coax run. Hmmm.

Missing from my 70cm DXCC list (now totalling 23 with Switzerland) are Jersey, Guernsey, Austria, Italy, Luxembourg and Slovakia, all within my best DX distance. I suppose I just need to try harder. 

1296MHz

As always, I enjoy 23cm contacts even though they are fewer and not so distant. The point is that as I am not expecting anything then everything is a bonus.

1296MHz contacts at GM4FVM 23 to 28 December 2025

Maybe these were not so far but they were interesting all the same. I had a good CW contact with F6DKW in JN18 square, 840km. This was the best DX on 23cm, with the two contacts to OZ2ND at 770km and OZ9PZ at 689km being FT8. With G3SQQ being SSB and G4YTL Q65 I covered a few modes. I also had several tries with other stations on CW, but propagation was against us. The main snag, which also affected the other two bands to a lesser degree, was very strong long QSB. I think it was possible that some of those attempted contacts would have succeeded if we had waited for a peak in the QSB.

In Summary

In my last posting I hoped that there would be some good openings soon, and the next day this started. Had I been looking at Hepburn? Well maybe but I cannot rely on predictions like that matching up to the real world. The real event was good in terms of length and stations worked, but it lacked a bit in terms of real DX. It added one more DXCC to the 2 metre 2025 list and one to the all-time 70cm list, and that is good. Also, I have now worked one new square on 2m and two new ones on 70cm. After 133 contacts I might have expected a wee bit more distance.  

Still, I can hardly complain. 

Now I can concentrate on trying to fix the winch. 

Nothing there to complain about.

At least it will keep me awake.

The Sound of Silence

 I have not been reporting much as not much has been happening.

This photo of me and Paddy below is not very complimentary. We were of course deep in conversation, my eyes closed in serious concentration. I admit that I was breathing slowly and very deeply, but this is just to help consideration of weighty technical matters. It was definitely not the case that radio conditions had driven me to sleep.

There were lots of things to work at times, but very long gaps in between.
 
The four propagation methods which are likely to apply at this time of year are - Sporadic-E, Meteor Scatter, Auroral, and Tropospheric.
 
Sporadic-E 

This has certainly been Sporadic.

Take for example 19 December 2025. Prior to this there had been very little on 6m for over a week. Then this:-

50MHz contacts at GM4FVM on 19 December 2025

Previous week - zero. 

Next day, 73 contacts into 17 DXCC, 39 squares, best DX to YT3N at 2044km. 

Following day - zero.

Such is the way things are at this time of year. 

Sometimes, like on 10 December, it also bursts forth, and other times it doesn't.

50MHz contacts at GM4FVM on 10 December 2025

That time it was 23 QSOs in 9 DXCC and 17 squares, with the best DX being UT7WZA at 1944km.

Once again, previous week - zero, and this time no more Es until 19 December. 

Weeks on end with no 6m contacts at all. I will not show a graph with no contacts on it. 

It would be easy to fall asleep with a cat on your lap and miss all this type of thing. Not me of course. I keep my guard up because you just never know. It could easily link into some real DX (but it didn't). 

 Meteor Scatter

I am not sure that I have the patience for much meteor scatter these days. Sometimes I would rather sit down and take a nap.

However, I was active using MSK144 on 14 and 15 December. There seems to be a lot less activity in Europe on meteor scatter these days than there used to be, especially on 6m which is now often missing any meteor scatter reports even during major showers. North America seems to have a lot more business. Anyway,it is still a good way to fill in some gaps in the square total.

Meteor scatter contacts at GM4FVM on 14 and 15 December 2025

On this diagram, 144MHz contacts are in green, 70MHz in red and 50MHz in blue. As they once said on the television snooker commentary, "for those watching in black and white the green ball is the one beside the blue" (that only makes sense if you know about snooker and are a bit colour blind, as I am).

Eight contacts in five DXCC, eight squares and best DX was OH8HTG on 2m at 1851km, OH7RJ on 6m at 1837km plus a very nice one to EA2LU at 1450km also on 2m. I also made my 126th meteor scatter QSO on 4m with Henning OZ1JXY. All very agreeable.

Auroral propagation

There have been predictions for several large auroras, but here the radio effects have been very meagre. I worked GM7PKT and M0XVF on Q65 on 50MHz on 12 December. Nice, but not great DX. Maybe we are due a major aurora event but if this is the down slope of the solar maximum I would have expected more. Or maybe the down slope of the solar maximum has not arrived yet ... ???

Tropo

There has not been a major tropo event here since 10 to 15 October. Perhaps I should write that one up. Still, I have been trying. I was taking part in part of the RSGB 432MHz UKAC FT8 contest on 10 December but conditions did not seem to be very good. Quite different was the 1296MHz version on 16 December.

1296MHz contacts at GM4FVMon 16 December 2025

Using SSB I worked six stations in three DXCC and six squares. I was only on for 45 minutes. Best DX was to MW0LKX/P at 380km. It is worth bearing in mind that this is only the second GW sations that I have ever worked on 23cm. I also worked G4CLA who is just 1km nearer but that QSO needed some aircraft scatter assistance.

A nice contact on 2m was with UT1FG/MM in JO25 square in the North Sea between me and Denmark. I have picked up a few watery squares over the years thanks to Yuri - long may he continue to brighten up otherwise dull silent days.

In Summary

Sudden bursts of activity with long gaps in between can be very frustrating. However, this shows my chosen mode of operation which is to spread out across the modes and bands. 

Is working 73 contacts in a day on 6m "better" than six in 45 minutes on 23cm? Not in my book, as in total it all adds up to me keeping on learning about radio. I especially enjoyed working some friends on SSB on 23cm, but I also really enjoyed the DX on meteor scatter.

In some strange way I enjoyed the many periods of complete silence too. If it was always busy it would be no fun, or not for me anyway. That gives me time to send QSL cards and fix various bits of electronic equipment brought round for repair by others in the village.

Perhaps we are about to get big openings on all bands and modes. I doubt if that would be better, but it would be a change. 

Now, I must get some sleep.
