-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"), [OK-DMRlib](https://github.com/OK-DMR/ok-dmrlib "OK-DMRlib"), 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, EDACS, OP25 Capture Bin compatability, etc. DSD-FME is primarily focused with Linux Desktop users, so please understand that this version may not compile, compile easily, 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.

 ## Notice
 
-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.
+This branch is for modifications to make a Windows 32-bit binary to be precompiled, please DO NOT use this branch if you are a Linux User, or copy any contents out of here to modify your existing setup!

-### 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.
-
-```
--ft XDMA decoder class (P25 1 and 2, and DMR Stereo)
--fs DMR Stereo, also may need to use -xr if inverted DMR
--fa Legacy Auto (not recommended)
--fi NXDN48
--fn NXDN96
--fp ProVoice
--fm dPMR, also may need to use -xd if inverted dPMR.
--fr DMR Mono, also may need to use -xr if inverted DMR.
--f1 P25P1
--f2 P25P2 (will need to specify wacn/sys/nac manually)
--fx X2-TDMA
-```
-
-## Trunking Examples
-Please see trunking.sh for sample start up scripts or scroll down to the bottom for more explanation.
-
-## Example Usage - Default Decoder, Ncurses Terminal, Pulse Input/Output, and Log Console to file
-`dsd-fme -N 2> voice.log`
-
-and in a second terminal tab, same folder, run
-
-`tail -n 40 -f voice.log`
-
-Then you can open up your pavucontrol "Pulse Audio Volume Control" or "Volume Control" application and route input into DSD-FME from any application and DSD-FME output to the left and right speakers respectively. (unlock the channel in the application stream and adjust left and right independently)
-
-### Input ###
-
---TCP Direct Audio Link with SDR++
-
-`dsd-fme -i tcp` Currently defaults to localhost:7355 (SDR++ defaults)
-
-`dsd-fme -i tcp:192.168.7.5:7356` (remote host and custom port)
-
---48000/9600 Mono Wav File Input
-
-`dsd-fme -i filename.wav` 48k/1 Audio (SDR++, GQRX wav recordings)
-
-`dsd-fme -i filename.wav -s 96000` 96k/1 (DSDPlus Raw Signal Wav Files)
-
-Wav File Input Note: Due to 96000 rate audio requiring me to double the symbol rate and center, be sure to use the -s 96000 at the very end of the startup command. Also, some NXDN48/96 may have difficulties decoding properly with wav file input. 
-
-## Example Usage - RTL2832 Dongle Input
-`dsd-fme -ft -i rtl:0:154.9875M:26:-2:8:0:6020 `
-
-```
-RTL-SDR options:
- WARNING! Old CLI Switch Handling has been depreciated in favor of rtl:<parms>
- Usage: rtl:dev:freq:gain:ppm:bw:sq:udp
-  dev  <num>    RTL-SDR Device Index Number
-  freq <num>    RTL-SDR Frequency (851800000 or 851.8M)
-  gain <num>    RTL-SDR Device Gain (0-49) (default = 26)(0 = Hardware AGC, not recommended)
-  ppm  <num>    RTL-SDR PPM Error (default = 0)
-  bw   <num>    RTL-SDR VFO Bandwidth kHz (default = 12)(6, 8, 12, 24) 
-  sq   <num>    RTL-SDR Squelch Level (0 - Open, 25 - Little, 50 - Higher)
-  udp  <num>    RTL-SDR UDP Remote Port (default = 6020)
- Example: dsd-fme -fp -i rtl:0:851.375M:22:-2:12:0:6021
-
-```
-
-## Example Usage - Extra Payload/PDU Logging
-
-`dsd-fme -Z -N 2>> log.ans`
-
-and in a second terminal tab, same folder, run
-
-`tail -n 40 -f log.ans`
-
-### EDACS/P25/NXDN/DMR Simple/Single VFO Trunking ###
-
-EDACS Trunking (w/ channel map import)
-
---EDACS/PV Trunking using RIGCTL and TCP Direct Link Audio inside of SDR++ (Tested and Working on EDACS/EDACS-EA with Provoice only, no analog voice monitoring)
-
-`dsd-fme -i tcp -fp -C channel_map.csv -G group.csv -T -U 4532 -N 2> log.ans`
-
---NXDN48 Trunking (standard band plan) with SDR++ (untested for frequency accuracy)
-
-`dsd-fme -fi -i tcp -T -U 4532 -N 2> log.ans`
-
---NXDN48 Trunking (w/ channel map import) with SDR++ (put control channel frequency at channel 0 in channel_map.csv)
-
-`dsd-fme -fi -i tcp -T -U 4532 -C channel_map.csv -N 2> log.ans`
-
---DMR Trunking (w/ channel map import) with SDR++ (put control channel frequency at channel 0 (TIII and Con+) in channel_map.csv)
-
-`dsd-fme -fs -i tcp -T -U 4532 -C channel_map.csv -N 2> log.ans`
-
---P25 Trunking P1 and P2 (C4FM) with SDR++ 
-
-`dsd-fme -i tcp -T -U 4532 -N 2> log.ans`
-
---P25 Trunking (CQPSK) with P1 Control Channel (Should switch symbol rate and center on Phase 2 audio channels)
-
-`dsd-fme -i tcp -T -U 4532 -N -mq 2> log.ans`
-
---P25 Trunking Phase 2 TDMA Control Channel systems with CQPSK (non Phase 1 systems)
-
-`dsd-fme -i tcp -T -U 4532 -N -f2 -m2 2> log.ans`
-
-Trunking Note1: All samples above can also be run with the RTL input method and setting of RTL UDP remote port. In terms of performance, however, SDR++ will do a much better job on weaker/marginal signal compared to the RTL input. RTL input should only be used on strong signal.
-
-`dsd-fme -fp -i rtl:0:851.8M:22:-2:24:0:6020 -T -C channel_map.csv -G group.csv -N 2> log.ans`
-
-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 setting a fake channel number (i.e. 999) first with the CC frequency will result in finding the CC faster on startup if desired. 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, but they seem consistent) 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.
-
-```
- Talkgroup Voice Channel Grant (TV_GRANT) - Logical
-  Ch [036] Cd [0054] C+ [0110] - TS [1] - Target [01900500] - Source [01900505]
-```
-
-Use channel 54 in your import file, which would correspond to dsdplus channels 109 and 110 (109 = TS0 / 110 = TS1).
-
-For Connect Plus, enumerate your list from 1 to the last channel and add the frequency. For Capacity Plus, Rest Channels 1 and 2 will share the same frequency, 3 and 4 will share, 5 and 6 will share, and 7-8 will share, as Capacity Plus counts each RF frequency as two seperate channels, one for each time slot. Capacity Plus Quirk: DSD-FME makes its best effort to follow the rest channel in the event that the sync is lost for longer than the hangtime, but occassionally, DSD-FME will lose the rest channel and will have to hunt through all frequencies to find it again.
-
-Currently uncoded/unknown DMR trunking systems include Hytera XPT.
-
-Trunking Note4: NXDN Trunking may also require a channel map file, depending on the system. If it uses a custom range (above 800), then channels will need to be mapped. If channels do not require mapping (have channels below 800) but you are not tuning properly, then please use a channel_map and please report the issue in the issues along with the channels you are tuning and the actual rf frequency so corrections can be made.
-
-Channel Map and Group CSV Note: Leave the top line of the channel_map.csv and group.csv as the label, do not delete the line, if no line is there, dsd_import skips the first line so it will not import the first channel or first group in those files if there is something there that isn't a label. 
-
-## NCurses Keyboard Shortcuts ##
-
-Some Keyboard Shortcuts have been implemented for testing to see how users like them. Just hope nobody pushes a key on accident and doesn't know which one it was or what it does. The current list of keyboard shortcuts include:
-
-```
-esc or arrow keys - ncurses menu
-q - quit
-c - toggle compact mode
-h - toggle call history
-z - toggle console payloads
-a - toggle call alert beep
-4 - force dmr privacy key assertion over fid and svc bits

-m - toggle c4fm/qpsk 10/4 (everything but phase 2 signal)
-M - toggle c4fm/qpsk 8/3 (phase 2 tdma control channel)
-R - start capturing symbol capture bin (date/time name file)
-r - stop capturing symbol capture bin
-spacebar - replay last symbol capture bin (captures must be stopped first)
-s - stop playing symbol capture bin or wav input file
-P - start per call decoded wav files
-p - stop per call decoded wav files
-t - toggle trunking (needs either rtl input, or rigctl connection)
-1 - Lockout Tuning/Playback of TG in Slot 1 or Conventional (Current Session Only)
-2 - Lockout Tuning/Playback of TG in Slot 2 (Current Session Only)
-0 - Toggle Audio Smoothing - May produce crackling if enabled on RTL/TCP or wav/bin files
-w - Toggle Trunking/Playback White List (Allow A Groups Only) / Black List (Block B or DE groups only) Mode
-g - Toggle Trunking Tuning to Group Calls (DMR T3, Con+, Cap+, P25)
-u - Toggle Trunking Tuning to Private Calls (DMR T3, P25)
-d - Toggle Trunking Tuning to Data Calls (DMR T3)

-
-Using the included download-and-install.sh should make for a simple and painless clone, build, and install on newer Debian/Ubuntu/Mint/Pi systems. Simply acquire or copy the script, and run it. Update: Ubuntu 22.04 and RPi Bullseye 64-bit has been tested working with the installer script and functions appropriately.
-
-If you need all dependencies build and installed first (only on Debian/Ubuntu/Mint/Pi), run:
-
-```
-wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/main/download-and-install.sh
-chmod +x download-and-install.sh
-./download-and-install.sh
-```
-
-If you have dependencies already installed (i.e. need a fresh clean install on a system with DSD-FME already or using system other than Debian/Ubuntu, etc), please run this instead:
-
-```
-wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/main/download-and-install-nodeps.sh
-chmod +x download-and-install-nodeps.sh
-./download-and-install-nodeps.sh
-```
-
-### Ubuntu 18.04/LM19/Buster Note:
-The above install.sh should now function on older system types. You can elect to manually follow the steps down below. Do NOT Manually build and install ITPP 4.3.1 on older systems, it is currently not wanting to build on Ubuntu 18.04 and Linux Mint 19. Install it from the repository instead.
-
-## Manual Install
-
-First, install dependency packages. This guide will assume you are using Debian/Ubuntu based distros. Check your package manager for equivalent packages if different.
