W3CSW (5886km) was the last USA station to spot my 10m 500mW WSPR this evening at 1802z. The last 10m WSPR USA station I copied was also W3CSW at 1808z. He was using 10dB more than I was! It seems that 500mW is quite enough usually if the band is open.
G0LRD (25km) - his 50mW is being consistently copied here.
G4IKZ (18km) - is copying me consistently all evening.
