Public community release. The complete working system — DSP + decoders (scripts/), web dashboard + API (dashboard/), container stack (docker/), config templates (config/) — plus APOCALYPSE-EDITION.md, the full build guide for a human or a coding agent. GPLv3 (PyEOT dependency). Scrubbed of all secrets, internal IPs, hostnames, and location detail. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# RTLSDR-Airband — istrain: an example voice-channel cluster (replace with YOUR subdivision — see APOCALYPSE-EDITION.md §3)
|
||
#
|
||
# Run in the foreground with live per-channel waterfalls:
|
||
# rtl_airband -f -e -c config/istrain.conf
|
||
# (-f = foreground + textual waterfalls · -e = errors to stderr · Ctrl-C to stop)
|
||
#
|
||
# One dongle (1002, Blog V4, TCXO). Five rail-voice channels demodulated SIMULTANEOUSLY (no
|
||
# scanning/camping — unlike the rtl_fm scan). The span 160.86–161.19 = 330 kHz fits inside a
|
||
# 1.024 MS/s window, which stays UNDER the USB sample-loss ceiling that bit the full 2 MS/s scan.
|
||
# Each channel records to its own file in /tmp/airband, and ONLY when squelch opens (continuous=false)
|
||
# — so the files stay small and hold real audio, not hiss.
|
||
#
|
||
# Primary (example) = 160.980 (AAR ch58), the road channel + the CJ 144.7 / 157.8 detectors. See CHANNELS.md.
|
||
# Tune squelch_snr_threshold up if it records noise, down if it misses weak transmissions.
