I upgraded from Mint 20.3 to Mint 21. CQRLOG works great except when I use a rig not connected to the computer and TRX control. There is a 0 (zero) permanently in the frequency display in TRX control and the NEW QSO frequency display. I cannot erase the 0 and when I try to manually enter a frequency it always reverts back to the 0. TRX control and New QSO frequency displays work perfectly when I'm using a rig connected to the computer.
Any help appreciated!
