In all, my 10mW ERP WSPR from the earth-electrode "antenna" in the ground was spotted by 4 stations with best DX DK2DB (685km). On RX, I spotted 10 stations with best DX LA2XPA (1310km).

I hope to be able to try MF WSPR using earth probes very shortly. I have a 80m to 630m Tx transverter ready, capable of running about 20W output although I will reduce this for WSPR. I may try 160m using the earth probes as well.
