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 73 de M0BMU
