Two answers to "can people debug this when it does not work".
They could not. A custom UDP row logged "sent 18 bytes to 127.0.0.1:12000"
and nothing about the message — which is a template the operator wrote, so
the byte count says nothing about whether the substitution came out as they
meant. The payload is now in the line, with the trigger that fired it, for
custom rows only: an ADIF record or a binary WSJT frame on every QSO would
bury the log rather than fill it.
Worse was the silent case. A template that is a single placeholder the trigger
does not carry — {freq} on a band change — renders empty, sends nothing, and
looked exactly like a row that had never fired. It now says so, throttled per
row, and points at the field list.
And a password in a URL is redacted before it reaches the file. Storing
http://admin:secret@switch/ as typed was a deliberate choice for LAN gear;
writing it into a log that gets sent to whoever is helping is a different
choice, and was never made.
The Settings section is "Connections" rather than "UDP integrations", since it
has not been UDP-only since the URL transport landed. The log prefix stays
"udp:" on purpose — renaming it would orphan every log an operator has already
sent and every note anyone has written against it.
The hard-coded emitters each speak one published format at one fixed moment.
This is the escape hatch, and it exists mainly for antenna switches: they are
driven by a URL, and the band change is the trigger they want.
Four triggers, each carrying its own field set: band change (the RADIO's band,
not the entry form — a switch follows the rig, not what is being typed), QSO
logged, rotator command and callsign lookup. The panel prints the fields the
selected trigger can fill, which is the point of the whole thing: a placeholder
the trigger does not carry renders as nothing, and without the list an operator
writes {freq} on a band change and has no way to learn why the switch never
moved.
Three things the panel cannot show, handled here:
- Escaping. A URL needs every value percent-encoded; a UDP payload must not
be touched. The first portable callsign, F4BPO/P, puts a path separator in
the middle of a query string otherwise — it works on the bench and fails on
the air.
- Blocking. An HTTP call to a switch that is unplugged would otherwise sit
for the operating system's timeout, on the path of a band change. It runs
in the background with a 3 s limit.
- Silence. A switch answering 404 after a firmware update fails exactly like
success looks from here, so the status code is logged, throttled per row.
The rotator trigger hooks the COMMAND rather than the SP/LP buttons, so the
compass and a spot click fire it too, and the path ("SP"/"LP") is passed
through because an azimuth alone cannot say which was taken — 137° is short
path to one station and long to another.
Credentials in a URL are stored as typed. That is the operator's call, on the
grounds that this is LAN gear, and the hint in the panel says so.
