First hardware test of node-26#9/#10 found three blockers:
- antirez/dump1090 has no --write-json, so ADS-B mode exited on start.
Swapped to wiedehopf/readsb; map alt_baro/gs (old names as fallback).
- op25 is not always on RTL-SDR index 0 (radio-box: op25 on 1, 0 free).
start() now tries each index and keeps the first decoder that stays up.
AIS-catcher index flag fixed to -d:N ("-d N" selects by serial).
- status() reported "running" for a decoder that died on startup: the
zombie still answered killpg(pgid, 0). Liveness now via Popen.poll().
install.sh blacklists dvb_usb_rtl28xxu, which claimed the second dongle.
Verified on radio-box: 831 msgs/min, 6 aircraft (3 with position) on a
9cm whip; op25 unaffected. AIS still untested.

# Secondary-SDR Container — node-26#9
|
|
#
|
|
# Claims the node's SECOND physical SDR (the first is always op25's). Mode is
|
|
# chosen at runtime via the control API, not baked in: dump1090 for ADS-B,
|
|
# AIS-catcher for AIS (op25_2 mode is not handled here yet — see node-26#9).
|
|
#
|
|
# Device claiming is by RTL-SDR index, not serial (op25's DeviceConfig.args
|
|
# has no serial concept either — see op25-container/app/models.py). Index 0
|
|
# is reserved for op25; this container always addresses index 1. That's a
|
|
# real limitation once serial-stable device binding matters (hot-unplug /
|
|
# replug can swap indices) — tracked in node-26#9, not fixed here.
|
|
#
|
|
# UNVERIFIED: this image has not been built or run against real hardware in
|
|
# this session (sandboxed authoring machine, no docker). dump1090 and
|
|
# AIS-catcher's exact CLI flags below are believed correct from their
|
|
# published docs but not confirmed against a real capture — the CTO/QA
|
|
# review before this ships to a real node should build and smoke-test it.
