I receive 472kHz via my transverter but on RX it is totally passive i.e. I receive directly on 472kHz on the FT817 through a series tuned circuit at 472kHz. Last night, mid evening, 472kHz WSPR was quite busy (see below):
On TX last night I was copied by 8 different stations with best DX last night G8HUH (250km). Best DX on the earth-electrode system (on TX with 5mW ERP) is DL-SWL (701km).
