JTDX polls get_ptt DURING transmit to confirm the rig is keyed (WSJT-X does not,
which is why it worked and JTDX cut after ~2 s). We answered a blanket "0" (RX),
so JTDX concluded PTT had failed and dropped the over. get_ptt now echoes the
last PTT state commanded via set_ptt — always consistent with the client's own
command. Trace showed T 1 → three t→"0" polls → T 0.
The optimistic get_freq echo added in 0.23.5 (to stop the "Fake It" dial creep)
stopped JTDX/WSJT-X from going into transmit: the client reads frequency back
during its TX sequence, and echoing the commanded value instead of the rig's
live value interfered with it. No-TX is far worse than a 0.5 kHz drift, so revert
to reporting the rig's live frequency. get_freq/get_split_freq return s.rig.Freq()
again; the echo state, noteSetFreq, reportedFreq and the drift test are removed.
A digital app (JTDX/WSJT-X) sharing OpsLog's rig in "Fake It" split follows
the dial by polling get_freq. Freq() is the last polled value and lags a
set_freq by a poll cycle, so right after a transmission the client read the
still-shifted frequency, mistook it for a manual QSY and adopted it — the dial
crept down every over and never came back. get_freq now echoes the last
commanded frequency until the rig confirms it (or a short deadline passes),
closing the race. Backend-agnostic, so it fixes every rig, not just Kenwood.
MSHV worked immediately, JTDX answered "Hamlib error: Invalid parameter while
setting frequency". The two use different Hamlib dialects: MSHV sends
"F 14074000", JTDX names the target first — "F VFOA 14074000". The VFO name
landed in the slot the frequency was read from, the parse failed, and we returned
RPRT -1, which is exactly the error JTDX reported.
A leading VFO name is now stripped from every command's arguments. It costs
nothing: OpsLog follows the rig's own VFO selection, so the name carries no
information we act on — but refusing it locked out a whole family of clients.
Both dialects are covered by a test, the plain one included, since this is an
addition and must not become a swap.
A rejected frequency is also logged with the raw line now. The client only shows
"Invalid parameter", which says nothing about what it actually sent — that is
why this took a screenshot to diagnose rather than a log.
A native CAT backend owns the rig's serial port, and Windows gives a COM port to
one process — so choosing native CAT locked WSJT-X, MSHV and JTDX out of the
radio entirely. That is the cost of dropping OmniRig, which was itself a sharing
layer, and it has to be paid back.
OpsLog now becomes the server, as wfview does. It speaks the Hamlib net rigctl
protocol, which every one of those programs supports natively (rig model "Hamlib
NET rigctl", 127.0.0.1:4532) with no driver to install. It sits in front of the
MANAGER, not a backend, so an operator on OmniRig, Flex, Icom or TCI gets the
same server.
Two details that decide whether a client works at all rather than degrading:
dump_state is parsed positionally and WSJT-X refuses to proceed without a
well-formed block, so it is written out in full and its shape is pinned by a
test; and set_vfo / set_split_vfo answer RPRT 0 rather than an error, because
OpsLog follows the rig's own VFO and a refusal makes WSJT-X abandon the
connection. Unknown commands answer RPRT -11 — never silence, which hangs a
client instead.
The whole protocol is tested against a fake rig, plus one end-to-end exchange
over a real socket, since the framing is as much the contract as the text.
Also: the Yaesu backend is confirmed working on a real FTDX10 (frequency, mode,
VFO, split), so its "not yet verified" note is now wrong and is corrected.
