The motorized-antenna follow loop keyed its deadband off the antenna's reported
frequency. A SteppIR reports an intermittent/stale status frequency (flips
between the commanded freq and its home/6 m value), so the deadband tripped on
almost every 1.5 s poll and re-issued a tune command. Each command refreshed
noteMotorMoveCommanded(), keeping motorTXInhibitLoop's recentCmd window alive, so
the Flex transmit-inhibit ("Interlock is preventing transmission") never
released — confirmed in a real log (moving=0 throughout, recentCmd was the
driver).
Follow loop now keys the deadband off the LAST COMMANDED rig frequency, only
re-tuning when the radio actually QSYs beyond the step — immune to a flaky
antenna status. Falls back to the antenna's freq only until the first command.
Also dropped SetTXInhibit's `interlock set reason=` sends: `reason` is a
read-only field on the Flex interlock object, so writing it is rejected
(cmd error 5000002D on V1.4.0.0) and did nothing; `transmit set inhibit=` is the
real mechanism and is unchanged.
