Hi David/All
That's interesting and I can now report that my WSPR is working once again! I found that I had to change FSK AdJ to 1,250 when previously it had worked without a hitch for weeks on 0,700!!
I'm currently tx every 2 mins while I check that all is ok and I'm getting reports back with drift of 0 and -1. My own monitoring is providing decodes again!!
I have to say that I'm really surprised that FSK ADJ has had to be increased so much with a minor shift in osc freq. Funny stuff this radio!!!
I will revert to 10mins tx shortly and leave it running this evening to see what happens, before I put the covers on again! Hopefully neither actions will stop it from working!!

Just to add my penny's worth...
Switched the UQRSS + GPS on this morning (into dummy load), not been on
since 15 August, I've been playing antennas having satisfied myself that I'd
got the UQRSS ready to go.
All appeared to start OK but my WSPR signal was no longer where I left it,
frequency had dropped and when I did find it could not be decoded.
So into "Test" mode to find the FSK lower than expected. Looking at the
"FSK Adj." setting, I'd documented leaving this set at 00,900 however found
it to be 00,700. Set back to 00,900 and FSK now correct.
Tweaked frequency but can only reach 10.140103 maximum so had to go with
that. WSPR now decoding again but showing DT errors of -1.4 to -2.1 seconds
(with GPS locked and PC suitably synced to a time server). Other received
signals are showing errors of less than 1.0 second. If anything I would
have expected the other way round?
Bad day in the shack!
