This is the boatbod fork of op25.
Capabilities are broadly categorized into two lists - those supported by the legacy "rx.py" version of the app and those by the newer "multi_rx.py" version. I recommend using multi_rx where at all possible as this is the focus of future development.
P25 Conventional (single frequency) P25 Trunking Phase 1, Phase 2 and TDMA Control Channel P25 Phase 2 tone synthesis Single SDR (dongle) tuning regardless of bandwidth TGID Blacklist, Whitelist with dynamic reloading TGID Priority with mid-call preemption Multi-system scanning (switches between multiple systems sequentially) TGID text tagging and metadata upload to Icecast server for streaming Dynamically controllable real-time plots: FFT, Constellation, Symbol, Datascope, Mixer, Tuning Dynamically controllable log level Curses or HTTP based terminal Demodulator symbol capture and replay Voice Encryption detection and skipping (configurable behavior) Automatic fine tune tracking for CQPSK demodulator (-X command-line parameter)
P25 Conventional (multiple frequencies) P25 Trunking Phase 1, Phase 2 and TDMA Control Channel P25 Phase 2 tone synthesis Motorola Smartzone Trunking (requires two dongles) Motorola Connect+ TRBO DMR Trunking (experimental, requires two dongles) DMR BS Mode (non-trunked) NBFM analog (conventional or Smartzone trunked) Multi-system/multi-channel concurrent operation (full time, not sequential) Single, Multiple and Shared SDR devices (e.g. wideband devices such as Airspy etc) TGID Blacklist, Whitelist with dynamic reloading TGID Priority with mid-call preemption TGID text tagging and metadata upload to Icecast server for streaming RID text tagging Dynamically controllable real-time plots: FFT, Constellation, Symbol, Datascope, Mixer, Tuning Dynamically controllable log level Curses or HTTP based terminal JSON based configuration DSD .wav and .iq file replay Dynamic demodulator symbol capture and replay (commanded through terminal) Voice Encryption detection and skipping (configurable behavior) Automatic fine tune tracking/caching for CQPSK demodulator (cqpsk_tracking parameter)
New HTTP GUI Logging to GUI Dynamic configuration
Forked from git://git.osmocom.org/op25 "max" branch on 9/10/2017 Up to date with osmocom "max" branch as of 3/3/2018 Note: as of 2019, codebase has diverged too far to continue syncing with osmocom
Many changes:
New command line options: --fine-tune : sub-ppm tuning adjustment --wireshark-port : facilitates multiple instances of rx.py --udp-player : enable built-in audio player --nocrypt : silence encrypted audio
NOTE 1: using the --nocrypt command line option will silence encrypted audio, but the trunking logic will cause the application to remain on the active tgid until the transmission ends. It is generally preferable to blacklist tgids that are always encrypted rather than simply silence them. Use the --nocrypt functionality to silence occasional encrypted transmissions on mixed use tgids.
NOTE 2: trunk id to tag mapping file (tgid-tags.tsv) can contain an optional 3rd numeric parameter to be used as the trunk priority when simultaneous calls are present on the system being monitored. Default priority is 3 if not explicitly specified. Lower numeric value = higher priority. Data columns are separated by a single TAB character.
e.g. 11501 TB FIRE DISP 2 11502 TB FIRE TAC2 3 11503 TB FIRE TAC3 3 11504 TB FIRE TAC4 4 11505 TB FIRE TAC5 3
