       "Fixed a motorized-antenna bug that could leave a FlexRadio permanently unable to transmit (‘Interlock is preventing transmission’). With a SteppIR whose status frequency reads intermittently (it flipped between the commanded frequency and its home value), the ‘follow the rig’ loop re-sent a tune command on almost every poll, and each command re-armed the ‘block TX while the antenna moves’ window — so the interlock never released. The follow loop now keys its deadband off the rig’s frequency (only re-tuning when the RADIO actually QSYs), immune to a flaky antenna status. Also dropped an ‘interlock set reason=’ command that SmartSDR rejects (it’s read-only) and only produced a harmless error line — the transmit-inhibit itself is unchanged and still holds TX safely while the elements move. New: a SteppIR ‘Tunable range’ setting (Settings → Hardware → Antenna, default 13–54 MHz = 20 m–6 m) — on a band outside it OpsLog leaves the antenna and TX completely alone, so tuning to 30 m on a 20 m–6 m SteppIR no longer tries to move it or touches the interlock.",
