Dear John,

Nil seen this morning - guess will have to wait until darkness.

I tried putting the numbers into the late G4FGQ's Grndwav3 ground-wave
calculating software. Assuming about 660km G3KEV - GM4SLV, 100mW ERP (=55mW
EMRP)and a sea path the whole way virtually, the received signal level
should be about 0.7uV/m,  which might be audible on a quiet band. For inland
stations, the ground wave losses increase a lot, so some sort of ionospheric
propagation probably will be essential for a successful QSO.

Cheers, Jim Moritz
