This mode is ideal for me. I put the RX on 50.280MHz and monitor what is spotted on PSK Reporter Maps on another PC in the lounge. Most signals come in strongly by reflections off the ionised trails of random meteors. Even with my poor antenna and coax I usually spot at least 10 countries on 6m most days. The pings may only be a few milliseconds long but WSJT-X V1.7 (free software) decodes the signals. Most signals I get are in the -1 to +3dB S/N range i.e. strong.
As it uses a different antenna, rig and no PC, I am also on 10m WSPR.
UPDATE 0840z: 12 stations in 3 countries so far on 6m MSK144 RX today. Nothing again on 10m.
UPDATE 1434z: 14 stations in 3 countries so far on 6n MSK144 RX and nothing still on 10m WSPR.
UPDATE 1634z: 15 stations in 4 countries on 6m MSK144 RX in last 12 hours. Nothing on 10m WSPR.
