Last night LA4ANA (1047km) copied my 5mW ERP from the earth-electrode “antenna” on 472kHz WSPR. This is my best DX yet on the non-antenna, nearly 300km further than my best previous TX record. I was also spotted by DL4YHF (556km) for the first time on the earth-electrode “antenna”. My PC decided to crash some time after midnight last night, so I missed any DX overnight. These spots were during the evening period.
In the last 2 weeks alone I have been spotted by 28 different stations when I’ve been using 5mW ERP from the earth-electrode “antenna” on 472kHz WSPR. Let no-one say 472kHz is out because they cannot fit an antenna! If my signal can span over 1000km with WSPR then you can surely do better. I make no claims for the earth-electrode “antenna” but if you are unable to erect a proper antenna give it a go.
I have still to try it at this QTH on 136kHz but at my old QTH I managed to be spotted at 250km with very low ERP.
