Map display of WSPR beacons heard on 630 m, from wsprnet.org
Early this morning I switched my radio on 475.6 - 475.8 kHz in the 630 m WSPR band for the first time. I
conencted my HF vertical antenna directly to the Icom IC-706 MkII radio,
without any matching, filtering or tuning. Only one station showed up, IW4DXW JN64 (1147 km).
