I got PTT putting out power by using DTR/RTS setting. CAT works for FREQ.
NOW i have an issue that the radio randomly shuts off and then comes back on. The off/on sequence may be quick or up to a minute or so. It appears to be when starting a series TX's.
Could it be the radio? Don‘t see how but . . .
Not sure how VarAC can be telling the radio to shut off.
