- op25-container/Dockerfile: clone gr310 then check out 5b58335 (OP25_COMMIT
build arg). That is the gr310 merge tk_drb_conv was verified against for
#29 and the first carrying PR #296's NBFM noise/voice squelch. Changing
the RUN line also busts CI's cached unpinned clone.
- Keys verified from op25_nbfm.py at that commit: nbfm_squelch_mode
(power|noise|voice), nbfm_noise_squelch_db, nbfm_squelch_threshold, read
from the channel dict.
- op25-container: ConfigGenerator.nbfm_squelch_mode (enum, default noise) and
nbfm_noise_squelch_db, written onto the analog channel.
- edge-node: system config squelch_mode / squelch_db / squelch_threshold ->
generate payload (validated, noise when absent); /api/listen and the
dashboard's analog pane expose mode and level.
#29's CI test of tk_drb_conv against the real tk_p25.py is not done here.

op25-container
- generate-config takes p25_mode "conventional" + conv_channels [{frequency,
name, nac}]. It builds fixed fsk4 channels (up to 2 on one non-tunable SDR,
DC spike kept off the channels) with no control channel to hunt. Two
channels send audio to UDP 23456/23457, and audio.py -2 + amplify(2) keeps
levels.
- tk_drb_conv.py (a tk_p25.rx_ctl subclass, copied into OP25 apps) reports
voice / NAC / encryption (LC service options + LDU2 ESS algid/keyid) for
conventional channels and applies the per-channel NAC filter, which stock
tk_p25 does not. Analog uses it too.
- Trunked P25 config is unchanged when p25_mode is absent.
drb-edge-node
- radio_config: system kind from type + config.mode (missing = trunked).
- conventional.py normalizes the console: a distinctive LC TGID, else the
channel's last TGID (30 s), else a synthetic per-channel id (freq/100 Hz).
Encrypted rows are never talkers. With exactly one conventional channel,
orphan audio is attributed to it at close, which fixes analog recording
(#20). The synthetic id and the real TGID on one channel never split.
- Health/dashboard: P25 conventional listen tab (/api/listen p25conv), and
conventional decode + encryption checks. The checkin carries radio_channels.
- Tests: edge 296 pass; op25-container 18 (new CI job). Reviewed by
drb-audio-review (findings fixed; simultaneous two-channel mixdown filed
as #26) and drb-qa-review.
Not verified on SDR hardware.

Adds a per-node secondary_sdr_mode config field (none|adsb|ais|op25_2),
applied the same way as hardware_preset/ppm_override so it survives system
reassignment. op25-container gets a GET /devices endpoint that counts
connected SDRs via lsusb; the edge-node checkin now reports sdr_count and
secondary_sdr_mode up to the server, the first node-initiated hardware
report (everything else was C2 pushing config down). Tracked as node-26#9.

`python:slim-trixie` carried no version at all, so a rebuild could move the
interpreter across a major release without anything in the repo changing. That
is not hypothetical here: app/models.py referenced IcecastConfig about 85 lines
before its definition and ran only because trixie currently ships Python 3.14,
where PEP 649 defers annotation evaluation. On 3.13 it was a hard NameError.
The ordering was fixed on 2026-08-16; the unpinned base outlived it.
Pinned to 3.14-slim rather than 3.14-slim-trixie so it matches drb-edge-node,
which was already on 3.14-slim. Patch releases still float, which is what we
want for security updates -- only the major version is nailed down.
Every other Dockerfile in both repos already pinned a major version
(python:3.12-slim, python:3.14-slim, node:20-slim, debian:bookworm-slim), so
this was the only genuinely unpinned base image, despite server-26#11 claiming
none of them were pinned.
Closeslogan/server-26#11 (filed against the wrong repo -- the file lives in
the client repo).
Both :8001 (FastAPI control API) and :8081 (OP25's HTTP terminal) listened on
0.0.0.0 with no authentication, on a container that is privileged with /dev
mounted and network_mode: host. Nodes get deployed to third-party sites, so
that exposed start/stop/retune to anyone on the host's LAN.
All three containers share the host network namespace, so edge-node still
reaches both over 127.0.0.1 unchanged. OP25_DEBUG_EXPOSE=true restores the
old 0.0.0.0 binding and logs a loud warning; it is off by default.
Confirmed against boatbod/op25 gr310 that the terminal's http:<host>:<port>
string is honoured as a real bind address (http_server.py splits it and hands
the host to create_server), so no flag was invented.
Also reorder models.py so IcecastConfig precedes ConfigGenerator, which
annotates a field with it. That only worked because python:slim-trixie is
currently Python 3.14, where PEP 649 defers annotation evaluation; on 3.13 or
earlier the same file is a hard NameError at import.

op25-container/system.pa New PulseAudio config: auth-anonymous=1 so the edge-node can connect without group membership
op25-container/Dockerfile Copies system.pa into /etc/pulse/system.pa
drb-edge-node/Dockerfile Added libpulse0 — ffmpeg needs this runtime library to use -f pulse
drb-edge-node/app/internal/call_recorder.py Switched recording from Icecast (burst-buffer overlap) to PulseAudio monitor (zero-delay, exact call boundaries)
