Two faults, reported from a real SunSDR.
DRIVE AND TUNE DRIVE DID NOTHING, and neither did MUTE. Those commands
carry the transceiver index — 'drive:0,15;', not 'drive:15;' — and sent
without it the radio ignores them silently: no error, no answer, the power
unchanged. The rule was in the radio's own reports all along, which is
where it should have been read from: it announces 'drive:0,85' and
'mute:0,false' at connect, while 'mic_level:100' and 'volume:-12' come
with no index at all. Sending the shape the radio speaks in is the whole
rule, and it is now written down next to the two exceptions.
AGC LOOKED STUCK ON SLOW. The panel showed only what the radio reported
back, on the principle that the radio is the truth — but ExpertSDR3 does
not echo every setting it accepts, so a working button sat unlit. Changes
are shown at once and held for a moment now; whatever the radio announces
afterwards still wins, so a clamped or refused setting stays honest
without every working one looking broken.
Also from the same report, and fair: the consoles did not resemble each
other. The Icom panel's RIT control is now a shared component both use —
chip, signed offset, ± keys, wheel, and TYPING a value straight in, which
is the thing a row of ±10/±100 buttons cannot do. Ctrl+←/→ shifts the RIT
here as it does there. And LONG is gone from the AGC row: the protocol
takes it, but it is a hang time nobody reaches for between overs.
TCI already carries the frequency, the mode, the meters and now the audio.
It also carries everything else about the radio — and OpsLog was logging
most of it once as '(unhandled once)' and throwing it away. The console is
mostly a place to put what was already arriving.
That makes it the cheapest panel here, and it is worth saying why. A K3
console costs a command and a reply for every value it shows, which is why
it reads its settings in a rotation and its meters only while on screen.
TCI PUSHES: the radio announces its drive, its filters, its noise blanker
and the rest on connect, and again whenever any of them changes —
including when the operator changes them in ExpertSDR3's own window, which
this panel therefore follows without asking anything.
What it drives: drive and tune drive, mic gain, TUNE, volume, mute,
squelch and its threshold, NB, NR, ANF, APF, AGC speed, the passband, RIT
and XIT with their offsets, and the VFO lock. The S-meter is a real dBm
reading, so its S units are arithmetic rather than the calibration guess a
K3's meter needs.
Setters never update the cached state. The radio answers with the new
value, and taking its word is what keeps the panel honest when a setting
is refused, clamped, or changed at the radio a second later — the one
exception being a slider mid-drag, held for 900 ms so it is not dragged
back by its own echo.
Capped width and centred, like the other consoles. Also offered as a
docked pane — and the Elecraft console is offered there too now: App has
always had that pane, Settings simply never listed it.
