+# 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"), [SDRTRunk](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 in mind, 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, Forts, thewraithe2008, RayAir, and others for the many hours of wav samples and information provided 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. I'd also like to thank mrscanner2008 for providing an additional remote where additional NXDN Type-C, 'Idas' Type-D, and XPT decoding and trunking could be sorted out. Thank you everybody.

+### 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
+```
+
+## New -- Experimental Conventional Frequency "Fast Scanner"
+This feature is used to allow DSD-FME to use RIGCTL or RTL input and cycle through frequencies as fast as possible to attain a frame sync. 
+
+This works almost identically to how the trunkng methods work, but instead of locking onto a control channel and tuning based on its decoding, it rapidly tunes through all loaded frequencies in a CSV file and stops when it finds a frame sync. This method is meant for loading a bunch of conventional non-trunking frequencies that signal only when voice or short data bursts are present (DMR T2, Conventional P25 P1, Conventional NXDN, etc) and decode them until the frame sync stops and then resume its scan. This method uses SDR++ RIGCTL, or RTL internal handling to go through signal. -Y is the fast scanner switch.
+
+To scan through a mixture of DMR and P25 Conventional, use:
+`dsd-fme -i tcp -C channel_map.csv -G group.csv -Y -U 4532 -N 2> log.ans` 
+
+To scan through NXDN48 only conventional, use: 
+`dsd-fme -fi -i tcp -C channel_map.csv -Y -U 4532 -N 2> log.ans` 
+
+To scan through NXDN98 only conventional, use: 
+`dsd-fme -fn -i tcp -C channel_map.csv -Y -U 4532 -N 2> log.ans`
+
+The Channel Map setup will be identical to any of the channel maps found for trunking systems, channel numbers do not matter and can be arbitrarily organized, and frequencies can be duplicated to be 'scanned' more frequently in larger CSV files. Scan speed is purely set by your CPU/GPU, and also by other factors like using SDR++ server to connect to a SDR++ client, or RTL_TCP server to client, etc, so faster computers scan faster, and slower will scan slower, slower scans may require multiple duplicate entries into your scanner csv file if you make a really large one.
+
+Please Note: DMR Simplex may not behave well on fast scan, I have not been able to test it as such, but given the nature of the on-off timeslot signalling on DMR Simplex, missed frame syncs and skipping/resuming scan may occur.
+
+## 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 'channel' as two seperate channels (LSN), 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.
+
+Trunking Note4: NXDN Trunking v1 will require a channel map. Please see the example folder for an appropriate channel map. NOTICE: NXDN trunking will not work properly with RTL input method due to the internal handling of the RTL dongle, when using squelch, it will effectively stop all processing (including trunking/tuning) until signal is regained, but squelch is required on NXDN to prevent false sync patterns.
+
+NXDN Trunking Update: NXDN DFA (Direct Frequency Assignment) has been coded from the v2 documents, so using a channel map may not be required, as long as the DFA is configured with standard values, and not 'system definable' values. This will only work on trunking systems that use DFA (newer systems) in accordance to the v2 CAI document NXDN TS 1-A Version 2.0 September 2016. If the system uses 'system definable' values, then make sure to put the channels in a channel map csv file as as the 16-bit OFN values for proper tuning.
+
+NXDN Type-D/IDAS Update: Type-D or IDAS decoding/trunking has been coded now and tested on a small two channel system. Set up a channel map much like Type-C trunking. If preferred, insert channel 31 at the top of your channel map for the 'home repeater' or go to channel of choice during a TX_REL or DISC message. Extensive testing of Type-D has not been conducted. Some cavaets may currently include iffy per call wav file saving and potentially shifting SRC and TGT ID values due to how SCCH messages are handled and how Busy Repeater Messages are handled. Private calls will need to be enabled by enabling 'data calls', if desired. During testing, only data calls came on private calls, so this was set to disabled by default, but can be enabled with data calls enabled. Also, note that some home repeater channels may or may not carry calls from all systems.
+
+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. 
+
+Hytera XPT: Experimental Code has been added for XPT system slco/flco/csbk decoding and trunking. The setup will be similar to Capacity Plus trunking in the csv file, listing each LSN channel to a frequency (see examples/hytera_xpt_chan.csv). Currently, this set up is working with smaller XPT systems that I have been able to test with.
+
+## 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
+i - toggle signal inversion on types that can't auto detect (dmr, dpmr)
+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

+MBELib is considered a requirement in this build. You must read this notice prior to continuing. [MBElib Patent Notice](https://github.com/lwvmobile/mbelib#readme "MBElib Patent Notice") This version of MBELib is 1.3.2 and prints to STDERR, using the stock 1.3.0 MBElib may cause problems with print alignments if paired with this version of DSD-FME, or cause future compatibility issues.
+
+```
+git clone https://github.com/lwvmobile/mbelib
+cd mbelib
+mkdir build
+cd build
+cmake ..
+make -j `nproc`
+sudo make install
+sudo ldconfig
+cd ..
+cd ..
+```
+
+Note: Some environment/distro users (Cygwin, Arch, and others) may need to manually copy any libmbe files found in the build folder to the /usr/lib folder on root.
+`sudo cp libmbe* /usr/lib`
+
+Finish by running these steps to clone and build DSD-FME.
+
+```
+git clone https://github.com/lwvmobile/dsd-fme
+cd dsd-fme
+sudo cp tone8.wav /usr/share/
+sudo cp tone24.wav /usr/share/
+sudo cp tone48.wav /usr/share/

+Optional 'Virtual Sinks' for routing audio from SDR++ or GQRX, Media Players, etc. into DSD-FME
+
+You may wish to direct sound into DSD-FME via Virtual Sinks. You may set up a Virtual Sink or two on your machine for routing audio in and out of applications to other applications using the following command, and opening up pavucontrol "PulseAudio Volume Control" in the menu (or `pulsemixer` in headless mode) to change line out of application to virtual sink, and line in of DSD-FME to monitor of virtual sink. This command will not persist past a reboot, so you will need to invoke them each time you reboot, or search for how to add this to your conf files for persistency if desired.
+
+```
+pactl load-module module-null-sink sink_name=virtual_sink  sink_properties=device.description=Virtual_Sink
+pactl load-module module-null-sink sink_name=virtual_sink2  sink_properties=device.description=Virtual_Sink2
+```
+
+Already have this branch, and just want to pull the latest build? You can run the rebuild.sh file in the dsd-fme folder, or manually do the pull with the commands:
+
+```
+##Open your clone folder##
+git pull
+##cd into your build folder##
+cd build
+cmake ..
+make -j `nproc`
+sudo make install
+sudo ldconfig
+```
+
+If the call alert wav files aren't playing, then make sure to run the following in the dsd-fme folder to copy the wav files to the /usr/share/ folder and give them adequate permission to be accessed.
+
+```
+sudo cp tone8.wav /usr/share/
+sudo cp tone24.wav /usr/share/
+sudo cp tone48.wav /usr/share/
+sudo chmod 777 /usr/share/tone8.wav
+sudo chmod 777 /usr/share/tone24.wav
