Hello Chris 
I removed the telephone line from the external shack and installed a cordless system, it made a small difference, and now there is also effectively a 30dB attenuator but it means smaller signals are not decoded which is a shame. I can see them on a  seperate spectrum analyser, Droitwich is about the same.
Now I have to deal with some spurious responses in Opera. This is running Opera, WSPR2 and 15, and Spectrum Analyser simultaneously which I always used to do. Have you checked the erp with anyone externally as any digital notch I put into the RF input is still too broad?
Hugh, M0DSZ

Hello Hugh,

It looks like you have managed to resolve the multiple signals from me
at your end, nothing has changed here, I have seen no multiple WSPR
receptions from you reported over the last couple of days, and signal
levels look more appropriate compared with other nearby stations,
here's last nights results:

 Is this now sorted? :) What was it if you don't mind me asking?
