Hi Irad,
For some reason, VarAC is not connecting to the Modem (see attached screen capture):
Everything else seems to be working fine: the modem waterfall gets a signal coming in, the PTT and frequency control are working, but the modem shows as disconnected, the VarAC "Connect" button is grey, and no signal seems coming in... Please advise. Thanks and 73, Avi 4X6LP
The "Disconnect" on the VARA modem window is normal if you are not in an active link. The "Disconnect Modem/Connect Modem" on the VarAC screen is normal. What is not normal is the waterfall in your VARA HF screen, your radio is not centered at 1500Hz, almost like a Yaesu radio where you have not set it up correctly.
