A few days ago I tried spotting on 137kHz WSPR. Nothing was copied.
I am wondering what modes are used mostly these days on this band? Perhaps WSPR is less popular on 137kHz than it once was.
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

Solar flux is 87 and the SSN 45. A=10 and K=1 .
OFCOM is seeking views on how best to use spectrum above 100GHz.
The cynic in me says they are really looking for how to make yet more money from licences. See the OFCOM website for more details.
Just think a few more 5G licences could bring in a few billions.....What a good way to make a bit more.
Reflex circuits originated in the valve era when valves were expensive. Reflex circuits allowed valves to be used as RF and AF amplifiers. The same idea can be used on transistor circuits. Although I have not tried it, this maybe a way of making a 10m AM RX with a narrower bandwidth than a super-regen? Sensitivity should be good.
I have the honour of me being asked by Clive Sinclair for advice!! Yes, he asked me for advice! This was in the 1970s when he was after an antenna for his pocket TV. I can remember this like yesterday. Quite an honour.
At the moment it looks like the current solar cycle (25) will be very similar to the last one and that a big peak is unlikely. At the moment, it is very slightly better than the last one.

At about 0820z, I turned on my 10m FT8 system. At first I was on TX of a very short while, but now am RX only. Nobody copied me. On RX, at 0831z, 3 stations have been spotted, with the furthermost ES5QA (1753km).
UPDATE 1411z: 103 stations spotted so far today on 10m FT8 RX.
UPDATE 1540z: 131 stations spotted so far today.
Yesterday's University of the Third Age lecture was by a Cambridge professor on the ethical reasons for a basic wage. It was very good.
Perhaps surprisingly, trials around the world have shown that this increases people willing to work and makes sound economic sense. The professor was Guy Standing, who is well respected across the world.
We are lucky to have a huge selection of courses in Cambridge.
Next week the speaker will be Jonathan Porritt.
My 10mW 6m WSPR is on again. As you will know this is to find out how well 10mW ERP might perform on 8m, which is available to all (certainl...
