I have tried WSPR 1.01 on 2 machines now: an XP Home PC, as well as a Vista Home Basic PC. Each one is having the same issue: at first, WSPR will transmit normally, and I get power out from my Yaesu. After about 15 minutes, the rig is keyed-up as normal, but there is no sound output to drive the rig. Is this normal, or is it a bug with the software?
