Audit prompted by "are we sure the commands are implemented — split, Fake It,
Split rig?". The rigctl server is complete and hardened; the TCI one, three days
old, had reintroduced a bug rigctld had already paid for.
A client working split says two things — where to transmit, and that split is
on — and nothing obliges it to say them in that order. A write to channel B
while the rig was still simplex was DISCARDED, on the sound principle that
preparing a transmit frequency is not a request to QSY. But then the split was
armed on whatever the transmit VFO held, which is the receive frequency: the
operator transmits straight onto the DX while their software shows exactly what
they asked for. The frequency is now remembered and used when the split arrives,
which is what rigctld does with set_split_vfo / set_split_freq.
Two more from the same source:
Asking for a split state the rig is already in touches nothing. A client in Fake
It uses no split but still says so to be sure, and answering an error to a
request that was already true is what made JTDX abandon a transmission a second
into the frame through the rigctl server.
A repeated PTT command is not re-sent. One client restated it sixteen times a
second, and the Flex's own "xmit 1" was overwritten between two of them inside a
millisecond. The same radio sits behind this server — the operator reporting
this is on the Flex API backend.
Fake It itself needs nothing but channel A, and now has a test saying so.
