Once sync'd to time (either using a BC receiver or internet time) it is totally stand alone and does not need a PC or external audio. It means I can operate on 6m WSPR or other modes (with the FT817 and PC) at the same time as using the WSPR beacon on 10m.
UPDATE 0820z: The 10m WSPR beacon has just been turned on.
UPDATE 0932z: No spots, as yet, of my 500mW 10m WSPR beacon.
UPDATE 1630z: With 8 different stations spotting my 500mW 10m WSPR beacon, the Es season is definitely here! Best DX today, so far, is OH2VMP (1734km).
