RECORDER_BACKEND=trunk-recorder (default op25, unchanged):
- tr_config: TR config.json + talkgroup/channel CSVs from the C2 system
config (P25 trunked, P25 conventional, analog with squelch).
- tr_calls: TR call JSON -> MQTT call_start/call_end + /upload fields
(talkgroup, start/stop, freq, units from srcList, emergency, encrypted).
- trunk_recorder: inbox ingest through the #44 spool with deterministic
call_ids, supervisor requests, live audio via simplestream -> pacat ->
drb_sink for Discord (one talkgroup at a time).
- radio_backend: start/stop dispatch so OP25 never grabs the SDR, and the
OP25 watcher/PulseAudio recorder stay off (no double uploads).
- health/dashboard/checkin show the active backend and TR health.

Fixes node-26#11. OP25's generated config said "rtl" (= whichever dongle
enumerates first), so on 2-SDR nodes a decoder could take OP25's dongle
and stop recording. Now:
- sdr_pins: {op25|adsb|ais: serial}, absent = automatic. Every OP25
config generation (op25_client.generate_config) rewrites the device to
rtl=<serial>: the pin, else the first dongle's serial, which is what
"rtl" always opened. Left as "rtl" only for unknown/shared serials.
- secondary-sdr: /secondary/devices lists dongles + serials via librtlsdr
(works while claimed). apply(priority, pins, reserved) never touches
OP25's dongle, gives a pinned service only its own dongle, lets a
higher-priority service take a spare from a lower one, and still runs a
pinned lower-priority service when the top pick has no dongle.
- sdr_settings.py replaces secondary_priority.py: one apply path for the
local dashboard, the new set_sdr_config C2 command (set_secondary_priority
kept as an alias) and config pushes. OP25 restarts only when its own
dongle changes. Checkin reports sdr_devices, sdr_pins, op25_sdr_serial.
- Local dashboard: 'SDRs' card with an OP25 SDR dropdown and a per-service
dongle dropdown, duplicate-serial and double-pin warnings.
Verified: edge-node pytest 194 passed; secondary-sdr tests 7 passed;
flake8 clean; page JS passes node --check.
