The SteppIR report was not a SteppIR fault. In the log the antenna starts, answers every poll, and sits at 21050 kHz while the rig works 21074 — and the status line only prints when the frame CHANGES, so a link that is alive and parked looks identical to one that died. The one line that explained it said "ultrabeam: follow loop stopped", which covers two quite different situations and, at startup where nothing was running, reads as a fault. Tracking was simply switched off. It now says which of the two it is, names the antenna type, and states the consequence — that the antenna will not follow the rig. Same log, a second and unrelated fault: every launch failed a tune request from DXHunter with "frequency 2107400000000 out of the 11-digit CAT range". <FREQ> was read as MHz, but DXHunter had echoed back the value OpsLog itself published in the N1MM RadioInfo broadcast, whose <Freq> is in tens of Hz. Both units come from the same peer, so the unit is now inferred: try MHz, kHz, Hz, tens of Hz, and keep the first that lands on an amateur band — anything a station is asked to tune to is in one. Hz before tens of Hz because their only overlap, 40 m against 4 m, is far more likely to be 40 m. Nothing plausible tunes nothing and says so, rather than sending the rig to a wrong band.
