137kHz transverter

From this QTH I have never tried 137kHz. At some point I really should. It is an interesting allocation. From the old QTH I copied a station in Sweden with just an E-field probe antenna. The transverter below was used on TX (see link below).

With QRP ERP from my old QTH it allowed me to be copied 250km away on WSPR. I forget the actual ERP but it was low mW at most. The antenna was either my earth-electrode antenna in the ground or my 80m square loop.
