The breadboard of my 137kHz TX transverter is now soak testing and putting around 30-35W RF into the earth-electode antenna sending WSPR-2 at 20%. The 10MHz oscillator will need its temperature stability improving before I try WSPR-15. At the moment I cannot RX on the transverter until the preamp and switching are added in a few days time..

ERP should be about 6dB higher than on the recent QRSS3 tests which have ended for now - thank you for the reports.

With WSPR-2's slightly better detection sensitivity (similar to QRSS10) and the extra ERP I am hopeful of a few spots.

I'll leave the set-up running this evening and would very much appreciate any 137.5kHz WSPR-2 reports please.
