I see there's a new version of Hamlib - 1.2.12. See http://forums.qrz.com/showthread.php?t=262622
The announcement includes:
Fixes and features: Paragon, TS-690S, FT-920, FT-990, FT-2000,
Elektor SDR-USB, IC-7000, IC-7700, AR-8200, AR-8600
Might be useful to anyone having issues with the above. It's possible to put the updated files into the WSPR program files directory (i.e. doesn't need a new WSPR release).
