The transmit meters are asked for four times a second while keyed, so
logging every arrival would fill an evening's log — and a diagnostic that
fills a log is one that gets switched off instead of read. Twenty of each
is enough to tell an answer from a silence, which is all it is for.
The log shows 'tx_power;' going out four times a second during a tune and
nothing coming back — but that proves less than it looks: a reply that
arrived and failed to parse leaves exactly the same trace as one that
never came. Both are now visible.
Two faults with one cause: this radio does not echo 'tune:0,true'.
So the panel never knew a tune was running. The button stayed on TUNE and
every further press sent another START — there was no way to stop it from
here at all. The state is recorded when the command is sent now; whatever
the radio says afterwards still wins, it simply never says anything.
And the transmit meters were asked for only while t.tx, which a tune
carrier does not set: the radio reports tuning as its own state, not as a
transmission. So power and SWR sat at zero for the whole tune — the exact
carrier an operator holds a tune for in order to watch an SWR on. They now
follow PTT or TUNE, and the S-meter reads '—' under our own carrier
either way.
TX_POWER and TX_SWR are read-only commands the radio answers when asked,
so they are asked for on each poll of a KEYED radio and not at all
otherwise: a receiving station pays nothing for meters nobody is watching.
Both appear next to the S-meter only while transmitting, because showing
them the rest of the time would show the last thing that happened as if it
were now.
An SWR of 0 draws as '—' rather than as 1.0. A perfect match on an antenna
nobody has measured is the one reading an operator should never be handed.
There is no temperature. The protocol's command list has TX_POWER and
TX_SWR and nothing thermal at all — so rather than leave the question
hanging, it is written down where the next person will look for it. A
temperature invented from something else, on a transmitter, is exactly the
kind of number somebody would trust.
250 now means 0-250. It meant 575-825: the width was right and it was
centred on the CW note, on the reasoning that a CW filter should contain
the note. That reasoning may be right for a radio and it is still wrong
here, because it is not what the button says — and a button that does not
do what it says is worse than one that does something simple. The two
edges are editable underneath for anything else, which is what TCI takes
anyway.
And MUTE still lights the squelch on a real radio. Nothing in this code
can do that — the button sends mute and only mute, and the two are
separate state — so the radio's own announcements are logged as they
arrive. What it says after the command will settle whether this is our
reading or its doing; no more reasoning from here will.
Three things reported from the radio, all of them mine.
THE LEVELS. Two half-width sliders side by side left each of them a couple
of centimetres long, which is not enough to set 15% with. One level per
row now, full width, with the value typed in or stepped with ± — and in
the radio's own units, so the volume is dB and the squelch a dBm
threshold, matching what ExpertSDR3's own window shows.
THE FILTERS. The button said 250 and the radio was set to 300-550: 250 Hz
wide, but sitting where no CW note is. The edges are computed from the
width now, and a narrow filter is CENTRED ON THE CW NOTE — a 250 Hz filter
from 100 to 350 would put the note outside its own passband. A button also
lights on the WIDTH the radio reports rather than on an exact pair of
edges, so moving one edge on the radio no longer darkens every button.
MUTE. Read from one shape only, while this radio reports the other
('mute:0,false'), so the button showed the opposite of the truth. Both are
accepted now.
None of this should have reached main before somebody had a radio in front
of it.
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.
