The network backend treated "control link alive but no CI-V reply" as the rig
being in standby, and tolerated it WITHOUT BOUND. When another program takes the
CI-V session — WSJT-X through OmniRig, or the Remote Utility — the rig goes on
answering pings on the control stream while sending us nothing at all. Alive()
stayed true, so ReadState returned the cached frequency with err == nil, the
Manager never saw a failure, never reconnected, and re-published a frozen number
with a fresh timestamp on every poll. Only restarting OpsLog cleared it.
Bounded now, on the last SUCCESSFUL read. Past the grace the error is reported so
the Manager tears the session down and reconnects, which re-takes the CI-V
stream. Also fatal immediately: the CI-V reader goroutine having exited — no read
can ever succeed after that, however healthy the control link looks.
The grace backs off to minutes when the silence persists, because the two cases
pull opposite ways: a stolen session recovers on the first attempt, while a rig
switched OFF is silent for hours and re-tearing its session every 30 s would
blink the panel — and its ON button — away continuously. A good read resets it.
The decision table is pinned by a test; the standby case (never answered since
connect) keeps the old tolerate-for-ever behaviour.
The rig's 0x27 waveform frames carry the same leading main-scope selector byte
as the dual-scope IC-7610/9700 (`27 00 00 <seq> <total> …`), but the code keyed
the layout off the CI-V address and treated the 7300 as selector-less, reading
the sequence from Data[1] (always 0x00) so every frame hit the `seq == 0`
guard and was dropped — blank scope. The waveform parser now detects the
leading selector byte from the frame itself (address-independent), and the
scope config/set commands (mode, span, edges) include the selector the 7300
requires. The IC-7610/9700 path is byte-for-byte unchanged (main → idx 2, sub
frames skipped). Confirmed against a real IC-7300 CI-V capture.
SetScope(false) sent both 0x27 0x10 00 (scope DISPLAY off) and 0x27 0x11 00
(CI-V data output off), so quitting OpsLog blanked a local IC-7300's own scope
screen. Only the display-on (0x27 0x10 01) is now sent, and only on enable;
disable stops the CI-V stream alone and never touches the radio's display.
The multi-frame waveform header (USB path) read the second frequency field
as an absolute high edge, but in center mode it is a span — so high < low and
the panadapter had no valid range to map the trace onto (blank scope). It now
applies the same center+span vs low+high disambiguation the IC-7610 single-
frame path already used. FIXED mode was unaffected.
