10m and 6m WSPR were closed down at 2030 and I have now moved to 630m (5mW ERP 20% and RX 80% without the preamp). Still using the earth-electrodes.
UPDATE 2205z: All the usual 472kHz "suspects", i.e. the active stations in western Europe, are being copied including lots of spots of EA5DOM (1525km) on the barefoot FT817 without the preamp. I think I'd spot him more often and at better S/N with the preamp in use.
