Managed to decode M0PPP tonight - see attached - for the first time.
Congrats!

No success here on 137.5kHz WSPR TX this evening, which was a disappointment.
Sorry to hear that but i know you'll see it as a challenge, which is good.

Some PA instability issues need resolving and, before Mal "the wise" tells me (again), yes I need more power.
Have you ever tried a standard vertical antenna? Just usual rain fall tube and cheep loudspeaker cable and a 10m vertical on the top of the house will give you up to 20 dB signal improvement at the same power levels i guess. I also decided to do my first transmissions with the new coil at 1W TX power, just to see what is possible :-)
