For a change today I am on 10m FT8. A before breakfast time CQ (2.5W) was spotted by no-one, but since then I have been RX only and there is Es evident with several eastern and southern Europeans spotted. So far, 9 stations spotted (0812z).
UPDATE 1526z: Currently 137 stations spotted on 10m FT8 RX today. Almost all are EU. One supposedly in Morocco has a Spanish EA1 call and may have his QTH locator details wrong. Another is in Ceuta, which is a small Spanish enclave in North Africa. Most of these are Es propagation I think.
UPDATE 1915z: It looks like just Europe and North Africa on 10m FT8 RX here today. There is no sign of any "real DX" on the band here today. No doubt better equipped stations will do better.

Mystery object - NOT amateur radio
We spotted this on a walk around the village yesterday. It was about 4 inches (11cm) across and very light, so not stone. It could be wood.
I think the colours are a mix of old paint and lichen. Whatever it is, it was odd.
When I picked it up the green bits lit up and it said, "take me to your leader". OK, I am kidding! 👻

6m FT8
Although I briefly called CQ (2.5W) earlier and got one spot from a G station 65km away, I have been mostly RX only. So far today, 7 spots with best DX DK8NE (702km). This could be Es or aircraft reflection.
UPDATE 1347z: Now 35 stations spotted on 6m FT8 RX today with best DX OH6DX (1918km) who was an amazing +10dB S/N.

10m WSPR TX
Quite early (before breakfast) WSPR spots of my 500mW beacon today.
UPDATE 1400z: Already 56 spots by TF1A (1798km) in Iceland today. A good job this station is there, as no other spots received! This station has been spotting me now for hours.
UPDATE 1937z: In the end just one station spotted me, but he managed spot me 71 times over a 4 hour period.

Was this an April fools joke that ran and ran?
For some weeks now I have seen articles reporting a novel VLF antenna that is extremely tiny. This is meant to be a TX antenna! Now, this may be genuine, but it has the ring of an April fools joke with legs! If you know this is genuine, please let me know.

Brain fog - NOT amateur radio
Earlier I was reading something about the hidden symptoms of MS and was struck by how similar these were to my own symptoms following my 2013 stroke.
On my feet I'm always giddy and I often say it is like living in a sort of continual fog and getting exhausted very quickly.
Outwardly I look well and indeed most people think that, 5 years on, I am fully recovered. Like MS sufferers, they have little idea!

Alan Turing - NOT amateur radio
I don't think this has been on before, but please accept my apologies if it has.
Alan Turing is perhaps the best known of the Bletchley Park code breakers in WW2. This plaque is on a wall in Cambridge.
There were others who came to light much later who were probably even more important, but the UK government kept their names secret including Bill Tutte (Google him!). There is a memorial to Bill in Newmarket.

10m WSPR TX
Well, the level of 10m WSPR activity has totally surprised me. Yet again, I was active with my little 10m, 500mW, WSPR beacon. This is 100% TX, 500mW, with randomised frequencies which change every 2 minute slot. Although this morning was quiet, 9 different stations have spotted me this afternoon! This totally self contained WSPR beacon needs no PC and is about as small as a pack of playing cards. In the last few years it has reached every continent including Antarctica. Amazing and real fun. All this with very modest wire antennas.
10m WSPR TX spots today so far. |
6m FT8
At about 1420z, I went on 6m FT8. There was Es about with several stations from central Europe. For a short while I called CQ (2.5W). Although no QSOs resulted I got spots from 5 stations with my best being a spot by 4O6ZD (1790km) in Montenegro. Clearly Es. On 6m FT8 RX several central European spots already plus Greece. The photo shows the stations spotted here on just a V2000 vertical omni in the last hour!

10m WSPR
After a brief go on 10m FT8 (TX and RX), I have switched to 10m WSPR. On 10m FT8 I was spotted by one EA3 when I was running 2.5W.
At the moment I am on WSPR 100% TX, 500mW, randomised frequencies on 10m and on 6m FT8 RX on a different antenna. I am told 10m WSPR activity is lower now that FT8 is very popular. We'll see. No 10m WSPR spots as yet.
UPDATE 0910z: Well, well, well! Already a spot from DK6UG (633km). This is quite early in the day and shows (probably) there is Es propagation.
UPDATE 1221z: Already spots by 3 different stations on 10m WSPR. Much better than I thought it would be on 10m WSPR.
UPDATE 1556z: 10m WSPR has been much better than I expected. As of a few minutes ago, no less than 7 different stations have spotted my little 500mW WSPR beacon with best DX being a spot by IZ3LCH (1149km).
UPDATE 1712z: Amazing! I have been "blown away" by the results on 10m WSPR TX today. Best DX is FY5KE (7110km).

472kHz WSPR overnight
It is definitely getting less busy! Overnight, I copied 6 stations , but only 3 stations spotted my 10mW ERP WSPR. The activity here overnight is shown in the table.
10m FT8
Although I have been on 10m FT8 RX since about 0800z, nothing yet spotted.
UPDATE 1125z: 6 stations spotted s far with best DX RX6AOB (2990km).
UPDATE 1300z: So far today 36 stations spotted. Looks like Es and some F2 earlier.
UPDATE 1902z: 299 stations spotted today with best DX on 10m FT8 RX being CX5ABM(11133km). Definitely Es and probably linking to F2 further south?
UPDATE 2101z: And still South Americans are coming through! At the moment 403 stations spotted on 10m FT8 RX today. Quite my best haul for a long while on 10m.
UPDATE 2115z: Now 405 stations spotted on 10m FT8 RX today with best DX CE2SQE (11473km). I was going to go on 472kHz, but I think I'll stop on 10m.

472kHz WSPR (10mW ERP)
Boyed by the successes of previous nights, I expect to QSY to 472kHz WSPR shortly from 10m FT8 RX. I shall probably give 10m FT8 a bit longer, just in case these is a late opening to South America. By 2005z I should be active on 472kHz WSPR. As on previous evenings I shall be using 10mW ERP from the earth-electrode "antenna" in the ground.
End-fed longwire antennas
These end-fed antennas are quite popular, but a 9:1 transformer is usually needed to bring the impedance down to levels that a typical rig's ATU can match. Often less than 3:1 VSWR can be obtained on all HF bands with such a transformer, so a rig's internal ATU can usually bring this down to 1:1.

Return to 10m FT8
At about 0845z today I returned to 10m FT8. Initially, I am calling CQ (2.5W) although shortly I shall be RX only.
UPDATE 0923z: No spots of my CQ, but I have spotted 3 stations in eastern Europe, presumably by Es.
UPDATE 1206z: Now 7 stations in 5 countries spotted so far today on 10m FT8 RX.
UPDATE 1635z: Now 13 stations in 7 EU countries spotted on 10m FT8 RX today.
UPDATE 1822z: 15 stations in 8 EU countries spotted today on 10m FT8 RX. I shall probably stay on 10m FT8 for another hour, then QSY to 472kHz (630m) WSPR overnight.
The map shows the stations spotted today on 10m FT8 RX to 1825z..

TV webSDR for Oscar 100?
Although I regularly check the narrowband SDR at Goonhilly in Cornwall, I am not aware of the equivalent for amateur TV signals. I know there are various standards and this may make such a RX difficult. I am aware of the SDR showing activity levels in the wideband transponder, but not actual TV signals. If you are aware of one, please let me know.
By the way, activity on the narrowband transponder still seems low.

That move to the right - NOT amateur radio
So the Ukraine has, allegedly, voted a clown as president. All over the western world it seems people are getting disillusioned with their elected representatives. There seems to be a march to the right in many countries. I am not quite sure why this is, but it points to disappointment and a sense of disconnectedness.
Like many things, this is probably cyclical, but it points to a deeper anxiety: we lack credible leaders.
Certainly here in the UK the gap between the richest and poorest in society seems to be growing and the poorer are being left behind. This cannot go on. At some point things will change, either peacefully or violently. Likewise we cannot continue to live on the principle of endless growth, when resources are finite.
