 # Digital Speech Decoder - Florida Man Edition

 DSD-FME is an evolution of the original DSD project from 'DSD Author' using the base code of [szechyjs](https://github.com/szechyjs/dsd "szechyjs"), some code and ideas from [LouisErigHerve](https://github.com/LouisErigHerve/dsd "LouisErigHerve"), [Boatbod OP25](https://github.com/boatbod/op25 "Boatbod OP25") and 
-[Osmocom OP25](https://gitea.osmocom.org/op25/op25 "Osmocom OP25") along with other snippets of code, information, and inspirations from other projects including [DSDcc](https://github.com/f4exb/dsdcc "DSDcc"), [SDTRunk](https://github.com/DSheirer/sdrtrunk "SDRTrunk"), [MMDVMHost](https://github.com/g4klx/MMDVMHost "MMDVMHost"), [LFSR](https://github.com/mattames/LFSR "LFSR"), and [EZPWD-Reed-Solomon](https://github.com/pjkundert/ezpwd-reed-solomon "EZPWD"), Eric Cottrell, SP5WWP and others. Finally, this is all brought together with original code to extend the fuctionality and add new features including NCurses Terminal and Menu system, Pulse Audio, TCP Direct Link Audio, RIGCTL, Trunking Features, LRRP/GPS Mapping, P25 Phase 2, etc, OP25 Capture Bin compatability, etc. DSD-FME is primarily focused with Linux Desktop users, so please understand that this version may not compile or run correctly in other environments.

 This project wouldn't be possible without a few good people providing me plenty of sample audio files to run over and over again. Special thanks to jurek1111, KrisMar, noamlivne, racingfan360, iScottyBotty, LimaZulu and others for the many hours of wav samples submitted by them. Most importantly, HRH17, whose insight, information, samples, and willingness to let me remote into a computer half-way across the globe in order to test trunking features are what make DSD-FME what it has become. Thank you everybody.

Any pre-compiled windows versions found in the release link will be considered legacy as well, and do not feature trunking support and have older handling for some other modes. Users are free to use those, but keep in mind the use case syntax may and will be different between versions. Furthermore, any wiki articles made for windows users may contain outdated information for building the pulseaudio branch, please adjust any information found in those accordingly.
+The pulseaudio branch has been deleted in favor of the new main branch which also uses Pulse Audio. Users moving to the main branch should review the help file and example usage files for changes in syntax. Users can download the last pulse audio branch version from the release link if they prefer the older version. Any pre-compiled windows versions found in the release link will be considered legacy as well, and do not feature trunking support and have older handling for some other modes. Users are free to use those, but keep in mind the use case syntax may and will be different between versions. Furthermore, any wiki articles with 'auto intstall scripts' made for windows users may contain outdated information for building the deleted pulseaudio branch, please adjust any information found in those accordingly.

+## Notice

+These examples will need to be modified to run on the 'lite' branch, or any precompiled Windows binaries released. (i.e. dsd-fme to dsd-fme-lite.exe, -i pulse -o pulse, etc)
+
 ### Example Usage and Notes!

 `dsd-fme` is all you need to run for pulse input, pulse output, and auto detect for DMR BS/MS, and P25 (1 and 2) . To use other decoding methods which cannot be auto detected, please use the following command line switches. Make sure to route audio into and out of DSD-FME using pavucontrol and virtual sinks as needed.

 Trunking Note2: CQPSK Phase 1 and Phase 2 Systems are subceptible to LSM distortion issues, but seem to do okay, but require really good signal. Some CRC issues still occur with Phase 2 TDMA LCCH Mac Signal that can affect reliability, I believe this issue is ultimately caused by the PSK demodulation inside of FME. I also don't believe this will work on 8-level PSK, but I cannot determine that at the moment. Update: I have improved the LCCH Mac Signal decoding my increasing the QPSK decision point buffers to their maximum values. 

-Trunking Note3: DMR Trunking has been coded, and some testing and tweaks have been carried out. Cap+, Con+, and TIII systems seem to do well with trunking now. Placing the frequency for the control channel at channel map 0 in your channel_map.csv file is not required now if using RIGCTL or the RTL Input, both can poll the VFO for the current frequency if it believes its on a control channel, but using channel 0 as the control channel will hardset that frequency to the control channel. If you need to map out your channels for TIII, you can observe the console output and look for channel numbers. For conveniece I have included the DSDPlus channel numbering (as best as I can figure it) into the console print so it will make it easier for users from DSDPlus to map frequencies into the channel_map.csv file. Make sure your channel numbers are the Cd (channel decimal) values from the log, and not the C+ (dsdplus) values. Notice: TIII Site ID value needs work to determine proper DMRLA values for system area and sub area.
