Sunspots still going down?

I just looked at the latest solar numbers predicted for the next few years. These make depressing readings.

They show sunspot numbers still falling until 2022 at least.  I very much hope they are wrong, although looking at the similarities with certain previous cycles on the Solan site they could be correct and we may well have a way down still to go despite the encouraging numbers earlier today.

Overall, not encouraging. Elsewhere, I read we may have already passed the solar minimum.

QSYed to 2m FT8

About an hour ago I QSYed to 2m FT8.  Initially I called CQ (2.5W) although nobody spotted me.  On RX 14 stations spotted in 6 countries with the best DX being GM0EWX (716km). Signal strength suggests aircraft reflection.

UPDATE 1841: At the moment, 29 stations in 6 countries spotted. A recent 2m FT8 CQ (2.5W to the big-whee omni) was spotted by 4 stations in 2 countries.

Christmas presents - NOT amateur radio

The photo shows our son opening his Christmas present this morning. He is a professional jazz pianist and is playing in Oxford today. We had Christmas dinner last night and are having bubble and squeak later.

UPDATE 1436z: The bubble and squeak was great. I actually prefer this to Christmas dinner. Although I enjoy meat, I could quite happily live without meat.

Another good session on 472kHz WSPR TX (10mW ERP)

Overnight was another good session on 472kHz WSPR TX (10mW ERP from the earth-electrode "antenna" in the ground). 28 stations have spotted me in the last day on the band with quite a few spots from Norway and Poland.

Christmas good wishes - NOT amateur radio

This time of year can be stressful for many: it is the season of goodwill and we are supposed to be happy although for many it can be hard. Emotions seem to be more intense: often good things seem better and sad things sadder. For those preparing Christmas dinners and getting presents for children it can be hard.

Whatever your situation - on your own, totally alone or surrounded by those you love have a good day. I recall one couple from work days who went camping in a tent in Scotland on Christmas Day!

Whatever, all the very best.

Sunspots (at last!) - Wednesday December 25th 2019

Solar flux is 73 and the SSN 24.  A=2 and K=0.

It just gets better and better on 472kHz WSPR TX (10mW ERP)

Last night was even better than the night before on 472kHz WSPR TX! As I write (0708z) Jan in Norway is still copying me!

Sunspots - Tuesday December 24th 2019

Solar flux is 73 and the SSN 0. A=4 and K=0.

Sirio 827 antenna?

Before the Es season next year I am looking for a well made antenna for 10m that will cover other higher HF bands via a tuner. I am told this antenna is well built, unobtrusive and works well.  I do not want beams and it must be unobtrusive.

Does anyone have any experience of this antenna?

These days I mostly use FT8 and WSPR because of my poor voice. My main HF interest is 10m (it always has been) but it could be useful to cover 20, 17, 15 and 12m too.

One of my problems is erection as I cannot do ladder work these days. Installation just outside the shack may involve some ladderwork (not high), fitting of coax and plugs, and a ground stake.

SAQ VLF CW (17.2kHz)

On December 24th (Christmas Eve) there is usually a special transmission from this historic alternator transmitter in Sweden. I am pretty sure they are not doing QSL cards this time.
