New to the mode. All seems to set up correctly but when sitting on the call frequencies the radio goes to transmit on occasion, perhaps when a CQ is received? No indication of the transmit activity on the operating screen and nothing shows up in the QSO or other logs. I can see beacons and CQ calls and broadcasts in the appropriate boxes. I hear activity on frequency but don't yet recognize tonal patterns so don't know what might be VarAC and what is other digital modes, nothing appears on the screen. Thanks!
