630m WSPR TX overnight


Last evening and overnight I was on 630m WSPR TX with my home-designed transverter into the earth-electrode "antenna" in the ground. A few years ago the measured ERP was 10mW. The transverter produces about 12W into a 50 ohm load. 17 stations spotted me (see table) with OH1LSQ (1733km) spotting me 9 times!
