8m or 6m?
In recent times, I have not been on 8m much, even though I have a UK T&I permit to TX on the 8m band.
The main reason is I know what the band can do with Es. It is possible to span the European continent with just a few milliwatts of FT8 on 8m.
The 8m band, being between 10m and 6m, comes into its own when the F2 MUF just exceeds 47MHz.
With the sunspot count being good recently, it has exceeded 50MHz, especially on N-S paths. Activity on 6m is much higher, so getting spots is easier than on 8m currently.
As the F2 MUF goes down, I expect 8m will be more useful showing how the F2 MUF can reach 8m, but not 6m. I shall probably try again on 8m this autumn It would be great if more PTTs allowed amateur access.
I hope the FCC, OFCOM and the RSGB are listening!

6m QRP FT8 (Tuesday)
UPDATE 0824z: 12 stations have spotted me. I think there is some Es.
UPDATE 0901z: IS0AWZ (1598km) has spotted me. See map.
UPDATE 1521z: 24 Europeans plus one CN8 have spotted me so far today. See map.
Changing images on my blog - NOT amateur radio
Quite often I need to change an image on my blogspot blog. I find this very "hit and miss". Sometimes I can do it easily and other times I struggle. I can't help thinking I am missing a trick and there must be a better way.
Does anybody know a method that just works please?
6m super DX
FETer transceiver (2008)
This was another of my attempts to get something for nothing!
It worked remarkably well, but I struggled with netting the RX onto the TX frequency so I was afraid of clobbering someone else. It was an adaption of a circuit for 40m by W2UW but made even simpler. It appeared in SPRAT some years ago.
Some have duplicated it and achieved some remarkable DX.

Over the horizon on 481THz (optical)
Before my 2013 stroke I enjoyed experimenting at optical frequencies and was amazed that I could decode my QRSS CW well over the horizon with no clouds in the sky. Sadly, my stroke put an end to this. The circuit diagram shows the beacon I used. As you can see it is simple.
