# Digital Speech Decoder - Florida Man Edition # 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, YSF, M17, 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.

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. Thanks to volo-zyko for cleaning up a lot of code. Thank you everybody. ## 2022.10.01 Update ##
![DSD-FME](https://github.com/lwvmobile/dsd-fme/blob/audio_work/dsd-fme2.png) Very Experimental (Mostly Just Sampling Speed and using built in QPSK demodulator) for Phase 2 CQPSK 6000 sps input over disc tap inputs (SDR++, GQRX, WAV files). Promising results, but some errors in decoding as expected. I've had some pretty good luck using SDR++ to listen to and decode Duke Energy TDMA Control Channel through the virtual sink. Experimental CQPSK can be toggled in Ncurses Menu and also via command line switch `-f2 -m2` but keep in mind this will only work with Phase 2 RF channels using CQPSK, and not a combined decoding.
![DSD-FME](https://github.com/lwvmobile/dsd-fme/blob/audio_work/dsd-fme3.png) Also, added some new iden_up PDUs and other odd and end P25 PDU's (still far from complete). Ncurses Terminal and Console output will now show relevant frequencies for CC and Voice channels if iden_up commands are present.
## Information DSD-FME, and The Florida Man Labs will be taking a hiatus period from straigth development of this project. Currently, I feel we are at a bit of a stand still as far as what can be done with the project without new demodulation, dibit buffer, audio, and input methods. DSD-FME will continue to receive maintenance updates for simple bug fixes and also any major bug issues that cause crashing, etc., but I am reluctant to continue developing with the current underlying issues mentioned above. I am going to go into a period of hiatus with this project and do lots of experimentation, learning, and testing to see what viable options are out there or need to be created from scratch. I feel like I've learned a lot, achieved a lot, made tons of mistakes, learned from a few of them, but ultimately improved on the DSD project. DSD-FME will continue to receive replies and support in any opened issues but will currently only extend to help in setting up and using the software, on top of regular minor maintenance and any crash related issues.
See the [examples](https://github.com/lwvmobile/dsd-fme/tree/audio_work/examples "examples") folder for information on [cloning and installing](https://github.com/lwvmobile/dsd-fme/blob/audio_work/examples/Install_Notes.md "cloning and installing"), [example usage](https://github.com/lwvmobile/dsd-fme/blob/audio_work/examples/Example_Usage.md "example usage"), and [trunking examples](https://github.com/lwvmobile/dsd-fme/blob/audio_work/examples/trunking.sh "trunking examples"). ## 2022.09.28 Mini Update ##
Back by popular demand, I've re-implemented DMR Stereo as a standalone decoder. DMR Stereo is also still available in XDMA decoding for P25 1, 2, and DMR BS/MS Simplex as well.
DMR Stereo `dsd-fme -fs`
XDMA `dsd-fme -ft`
It can also be selected in the NCurses Terminal Menu. Sadly I had to remove the X2-TDMA decoder option in the menu, I'm sure nobody will miss it.
## 2022.09.17 Update ##
P25 Phase 2 Audio decoding has been implemented into DSD-FME. Currently, Phase 2 will only work from OP25 symbol capture bin files, or from wav files/SDR applications/RTL input that are sourced from FSK4 sources. CQPSK (LSM/H-D8PSK) will not work from audio sources. With the addition of Phases 2 audio, a new default decoder class has been implemented, XDMA, which is P25 Phase 1, Phase 2, DMR BS and MS (DMR Stereo). Furthermore, very limited Phase 1 TSBK support and Phase 2 FACCH/SACCH/LCCH has been worked in just to get Network Status Broadcasts, which can fill in the required P2 parameters for WACN, SYSID, and CC for Phase 2 frame de-scrambling, and active voice call information.
With the implementation of the XDMA decoder class (default decoder), the CLI switches for DMR Stereo has been repurposed. -T option will now open a per call wav file saving when used with NCurses Terminal, otherwise it will write wav files to slot 1 and slot 2 wav files.
Anybody using `dsd-fme -fr -T` ...... should now just use `dsd-fme -ft` instead!
To see the up to date CLI options, please look at the help options with the -h CLI option.
## 2022.08.12 Update ##
A new menu system has been introduced in the NCURSES Terminal. Also includes support for LRRP to text file type of choice and reading OP25 symbol capture bin files.
[![DSD-FME](https://github.com/lwvmobile/dsd-fme/blob/pulseaudio/dsd-fme.png)](https://www.youtube.com/watch?v=TqTfAfaPJ4s "DSD-FME Update 2022.08.12")
To get started with the new menu system, simply launch with:
`dsd-fme -N 2> log.txt`
## 2022.06.20 Update - Current Users Please Read!! ##
The executable for this project has been changed from `dsd` to `dsd-fme` so after pulling or cloning the lastest version, make sure to call the software with `dsd-fme`.
## 2022.05.05 Update ##
DMR Stereo method added for listening to voice audio in both TDMA channels/slots simultaneously.
### Example Usage and Note!
`dsd-fme` or `./dsd-fme` may need to be used in your usage, depending on if you are running it from the build folder, or if you have run make install. You will need to tweak the examples to your particular usage. Users can always check `dsd-fme -h` for help and all command line switches to use.
`dsd-fme` is all you need to run for pulse input, pulse output, and auto detect for DMR BS/MS, P25 (1 and 2) and X2-TDMA decoding. 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, DMR BS/MS, X2-TDMA)
-fs DMR Stereo BS/MS Simplex
-fa Legacy Auto
-fi NXDN48
-fn NXDN96
-fp ProVoice
-fm dPMR, also may need to use -xd if inverted dPMR.
-fr DMR, also may need to use -xr if inverted DMR.
-f1 P25P1
-fx X2-TDMA
```
## Example Usage - New XDMA Decoder, Ncurses Terminal, Pulse Input/Output, and Log Console to file
`dsd-fme -ft -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)
## Example Usage - RTL2832 Dongle Input
`dsd-fme -fi -i rtl -c 154.9875M -P -2 -D 1 -G 36 -L 70 -U 6021 -Y 12`
```
-i rtl to use rtl_fm (default is -i pulse for pulse audio)
-o pulse to set output to pulse audio (excluded, is default anyways)
-c Set frequency
-P set PPM error (default = 0)
-D set device index number (default = 0; first device detected)
-G set device gain (0-49) (default = 0 Auto Gain)
-L set rtl squelch to 70 (default = 0; off)
-U set UDP port for rtl_fm remote control (default = 6020)
-Y 12 set rtl VFO bandwidth in kHz, (default = 12)(6, 8, 12, 16, 24, 48)
```
## Example STDIN UDP from GQRX or SDR++, output to Pulse Audio, and append decoded audio to wav file
Be sure to first start UDP output sink in GQRX or SDR++ and set VFO appropriately
`socat stdio udp-listen:7355 | dsd-fme -fi -i - -w nxdn.wav`
## Example Usage - Extra Information for Academic Study and Logging
`dsd-fme -Z -N 2>> voice.log`
and in a second terminal tab, same folder, run
`tail -n 40 -f voice.log`
![DSD-FME](https://github.com/lwvmobile/dsd-fme/blob/pulseaudio/dsd-fme2.png)
## Roadmap
The Current list of objectives include:
1. New demodulators and input method(s) (considering liquid-dsp).
2. Graphical User Interface (may need to migrate to new project).
3. Lots of experimentation.
## How to clone, check out, and build this branch
### Ubuntu 22.04/20.04/LM20/Debian Bullseye or Newer:
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/pulseaudio/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/pulseaudio/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.
```
sudo apt update
sudo apt install libpulse-dev pavucontrol libsndfile1-dev libfftw3-dev liblapack-dev socat libusb-1.0-0-dev libncurses5 libncurses5-dev rtl-sdr librtlsdr-dev libusb-1.0-0-dev cmake git wget make build-essential libitpp-dev libncursesw5-dev
```
## Headless
If running headless, swap out pavucontrol for pulsemixer, and also install pulseaudio as well. Attempting to install pavucontrol in a headless environment may attempt to install a minimal desktop environment. Note: Default behavior of pulseaudio in a headless environment may be to be muted, so check by opening pulsemixer and unmuting and routing audio appropriately.
```
sudo apt install libpulse-dev libsndfile1-dev libfftw3-dev liblapack-dev socat libusb-1.0-0-dev libncurses5 libncurses5-dev rtl-sdr librtlsdr-dev libusb-1.0-0-dev cmake git wget make build-essential libitpp-dev libncursesw5-dev pulsemixer pulseaudio
```
### Build and Install ITPP - ONLY IF NOT IN REPO!!
```
wget -O itpp-latest.tar.bz2 http://sourceforge.net/projects/itpp/files/latest/download?source=files
tar xjf itpp*
#if you can't cd into this folder, double check folder name first
cd itpp-4.3.1
mkdir build
cd build
cmake ..
make -j `nproc`
sudo make install
sudo ldconfig
cd ..
cd ..
```
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 1.3.1 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 issues with printing over the screen in future builds.
```
git clone https://github.com/lwvmobile/mbelib
cd mbelib
mkdir build
cd build
cmake ..
make -j `nproc`
sudo make install
sudo ldconfig
cd ..
cd ..
```
Finish by running these steps to clone and build DSD-FME w/ pulseaudio support.
```
git clone https://github.com/lwvmobile/dsd-fme
cd dsd-fme
git branch -a
git checkout remotes/origin/pulseaudio
git checkout -b pulseaudio
git branch -a #double check to see if you are on pulseaudio branch
sudo cp tone8.wav /usr/share/
sudo cp tone24.wav /usr/share/
sudo chmod 777 /usr/share/tone8.wav
sudo chmod 777 /usr/share/tone24.wav
mkdir build
cd build
cmake ..
make -j `nproc`
##only run make install if you don't have another version already installed##
sudo make install
sudo ldconfig
```
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.
```
pacmd load-module module-null-sink sink_name=virtual_sink sink_properties=device.description=Virtual_Sink
pacmd 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 https://github.com/lwvmobile/dsd-fme pulseaudio
##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 chmod 777 /usr/share/tone8.wav
sudo chmod 777 /usr/share/tone24.wav
```

## Audio Plumbing
While using DSD-FME to demodulate and decode RF Audio, you will find it necessary to properly plumb (or route) audio from each input source and output sink properly. This mini tutorial aims to help you do such when using Pulse Audio.
You will first want to locate and run the virtualsink.sh script file via `sh virtualsink.sh` command. This will create two null-sink, or 'virtual sinks' for us to plumb audio from point A to point B.
Here are screenshots of a proper setup using pavucontrol, or "Pulse Audio Volume Control", having voice input from the encoder listening to your microphone, the RF Output going into the "Virtual_Sink" null-sink, and on the playback side, playing back voice to our speakers, with RF modulated audio being monitored on "Virtual-Sink" null-sink.
![Audio 1](https://github.com/lwvmobile/dsd-fme/blob/aw_dev/examples/pavucontrol_plumbing1.png)
![Audio 2](https://github.com/lwvmobile/dsd-fme/blob/aw_dev/examples/pavucontrol_plumbing2.png)
The general idea is that we want to route RF modulated audio into our Virtual_Sink and have our decoder listen to the same sink. Voice Output should always be to Audio Hardware (speakers, headphones, etc).
Note, that using the virtualsink.sh will create these sinks for us for the duration of your computers boot. If you reboot, they will not persist. Configuration files can be modified to always have these sinks available, or the `virtualsink.sh` script can be executed on login, but you must do so at your own risk and own research, it is out of the scope of this tutorial to create persistent sinks.
In case of the usage of a headless environment and pavucontrol is not viable, you may use alternatives such as pulsemixer which is similar in functionality, just as a CLI tool and not a GUI tool.
Users can now use the `-O` CLI argument to list out all pulse audio input sources and output sinks and pass an optional argument alongside `pulse`, appending the name or index number to select the device each time. This method will work in both Linux environments as well as Cygwin builds (making sure to start the pulseaudio.exe server in the back first with the specified .bat file or command, see below).
For Example:
The Output (truncated) of `dsd-fme -O`
```
=======[ Output Device #1 ]=======
Description: Family 17h (Models 00h-0fh) HD Audio Controller Analog Stereo
Name: alsa_output.pci-0000_0d_00.3.analog-stereo
Index: 1
=======[ Output Device #4 ]=======
Description: Virtual_Sink1
Name: virtual_sink1
Index: 4
=======[ Output Device #5 ]=======
Description: Virtual_Sink2
Name: virtual_sink2
Index: 5
=======[ Input Device #2 ]=======
Description: Family 17h (Models 00h-0fh) HD Audio Controller Analog Stereo
Name: alsa_input.pci-0000_0d_00.3.analog-stereo
Index: 2
=======[ Input Device #5 ]=======
Description: Monitor of Virtual_Sink1
Name: virtual_sink1.monitor
Index: 5
=======[ Input Device #6 ]=======
Description: Monitor of Virtual_Sink2
Name: virtual_sink2.monitor
Index: 6
```
You might use any of the following for input and output options:
```
-i pulse
-i pulse:6
-i pulse:virtual_sink2.monitor
-o pulse
-o pulse:1
-o pulse:alsa_output.pci-0000_0d_00.3.analog-stereo
```
Something to keep in mind is that often times, you only need to set these values once, as a pulse audio server (or plugin) can often times remember these settings, even across reboots, as long as the same hardware is present for future use (real or null-sink).
<!-- TODO: Add This later -->
<!-- Cygwin Note: Running the supplied `0p - start-pulse-audio-backend.bat` file will not only start up the pulse audio server for you, but also setup your null-sinks, and enumerate all devices for you to use, making it an easy selection for your start up .bat files. See any notes in the precomplied .zip file for more information. -->

### 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. To use other decoding methods which cannot be auto detected, please use the following command line switches.
```
-ft XDMA decoder class (P25p1 and p2, YSF, 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
-fh EDACS Standard / Network
-fH EDACS Standard / Network with ESK
-fe EDACS Extended Addresssing
-fE EDACS Extended Addressing with ESK
-fm dPMR, also may need to use -xd if inverted dPMR.
-f1 P25P1
-f2 P25P2 (may need to specify wacn/sys/nac manually if traffic channel)
-fx X2-TDMA
-fy YSF
-fz M17 Audio
```
## Conventional Frequency Scanner
This feature is used to allow DSD-FME to use RIGCTL or RTL input and cycle through frequencies 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 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 scan switch. Note: This method will NOT perform at a level similar to a real hardware scanner, SDR tuning is not nearly as fast or reliable at locking onto signal.
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 NXDN96 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 by default is 1 second, and is most stable at that speed. This can be adjusted by using the `-t 2` option, for example, to specify 2 seconds of hang time per frequency. ~~If activity occurs on a frequency, an additional 2 seconds of 'hangtime' will occur on that frequency for any follow up voice activity.~~ Using `-t 0` will forego the one second wait time, and this can work in some situations, but is not advised as it may skip during the middle of transmissions, or skip over them entirely without a framesync.
Please Note: DMR Simplex may not behave well on 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`
### Audio Plumbing
Please see [Audio Plumbing](https://github.com/lwvmobile/dsd-fme/blob/aw_dev/examples/Audio_Plumbing.md "Audio Plumbing") for general help with audio plumbing (routing from A to B).
### 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
Short Setup (all default values):
`dsd-fme -i rtl`
Detailed Setup:
`dsd-fme -ft -i rtl:0:154.9875M:26:-2:8:0:6020 `
```
RTL-SDR options:
Usage: rtl:dev:freq:gain:ppm:bw:sq:vol
NOTE: all arguments after rtl are optional now for trunking, but user configuration is recommended
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 = 0; Hardware AGC recommended)
ppm <num> RTL-SDR PPM Error (default = 0)
bw <num> RTL-SDR Bandwidth kHz (default = 12)(8, 12, 16, 24)
sq <num> RTL-SDR Squelch Level vs RMS Value (Optional)
vol <num> RTL-SDR Sample 'Volume' Multiplier (default = 2)(1,2,3)
Example: dsd-fme -fs -i rtl -C cap_plus_channel.csv -T
Example: dsd-fme -fp -i rtl:0:851.375M:22:-2:24:0:2
```
## 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++ (see switches above for STD/NET, EA, and ESK modes)
`dsd-fme -i tcp -fE -C channel_map.csv -G group.csv -T -U 4532 -N 2> log.ans`
--NXDN48 Trunking (Direct Frequency Assignment) 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 (QPSK) 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 QPSK (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: QPSK Phase 1 and Phase 2 Systems may be 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 style LSN-esque numbering 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 lpcn (12-bit logical physical channel number - decimal format) values from the log, and not the LPCN+TS (13-bit DSDPlus LSN) values. Notice: TIII Site ID value needs work to determine proper DMRLA values for system area and sub area.
```
00:43:00 Sync: +DMR [slot1] slot2 | Color Code=00 | CSBK
Talkgroup Voice Channel Grant (TV_GRANT) - Logical
LPCN: 0075; TS: 2; LPCN+TS: 0152; Target: 16518173 - Source: 16533625
```
Use channel 75 in your import file, which would correspond to dsdplus channels 151 and 152 (151 = TS1 / 152 = TS2).
For Connect Plus, enumerate your list from 1 to the last channel and add the frequency. For Capacity Plus, LSN 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 may 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 has been fixed on the RTL (rtl_fm) input method and works correctly now using a soft squelch value to determine when to look for frame sync. Tests show this works very well, but squelch adjustments may be required to differentiate the noise floor from the signal.
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: 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.

```
Note: Do not run this command for ffmpeg/icecast piped to the main dsd-fme command, make sure these are running in seperate terminals.
## Sending Audio to UDP Target/Port
Audio can be sent to a target address on your local area network with the UDP blaster using the `-o udp:targetaddress:port` option.
Note: Any analog audio monitoring will not function properly over UDP port (rate difference issues)
Example (Short 8k/2):
`dsd-fme -fs -o udp:192.168.7.8:23470`
Receiving End (Short 8k/2):
`socat stdio udp-listen:23470 | play --buffer 640 -q -b 16 -r 8000 -c2 -t s16 -`
Example (Short 8k/1):
`dsd-fme -f1 -o udp:192.168.7.8:23469`
Receiving End (Short 8k/1):
`socat stdio udp-listen:23469 | play --buffer 320 -q -b 16 -r 8000 -c1 -t s16 -`
Example (Float 8k/2):
`dsd-fme -ft -y -o udp:192.168.7.8:23468`
Receiving End (Float 8k/2):
`socat stdio udp-listen:23468 | play --buffer 1280 -q -b 16 -r 8000 -c2 -t f32 -`
Example (Float 8k/1):
`dsd-fme -fi -y -o udp:192.168.7.8:23467`
Receiving End (Float 8k/1):
`socat stdio udp-listen:23467 | play --buffer 640 -q -b 16 -r 8000 -c1 -t f32 -`
Note: --buffer option in play is calculated by (channels * samples * sizeof(samples)),
where samples is 160 for mono, 320 for stereo, and short samples are 2 and float samples are 4.
This is vital to prevent 'lag' or cut-off audio when the UDP audio doesn't fill the default buffer size.
Note2: Be sure to start the receiving end AFTER starting DSD-FME. If DSD-FME is restarted, make sure to restart the receiving end as well, as socat/UDP closes the UDP port listening when DSD-FME closes the UDP socket.
Note3: socat version 1.8 may have a `E xioopen_ipdgram_listen(): unknown address family 0` problem, downgrading to 1.7.4 is recommended if this occurs. `sudo downgrade socat`.
## Record 48k/1 audio with rtl_fm
You can record suitable audio to feed as input to dsd-fme with `-i` using rtl_fm:
`rtl_fm -M nfm -f [FREQ] -s 48k -g 42 -l 20 > input.wav`
You can also combine that with `socat` to send the audio to a remote dsd-fme instance in real time while keeping a local copy on the host where the RTL-SDR dongle is:
`rtl_fm -M fm -f [FREQ] -s 48k -g 42 -l 20 | tee input.wav | socat -u - TCP-LISTEN:1234,forever,reuseaddr`
On the remote side where dsd-fme is, use the TCP input:
`dsd-fme -i tcp:192.168.7.8:1234 -N`
Note: As always, when using rtl_fm, play with `-l` and `-g` to find a good squelch and gain values for your environment - you will know if the squelch is the right value when `input.wav` does not increase in size in the absence of useful signal on the monitored frequency.
## Using the Experimental M17 Encoder (and Decoder)
You can use the experimental M17 Voice Stream and Packet encoder with the following examples.
Encode/Decode Local Feedback Voice Stream (Single Session):
`dsd-fme -fZ -i pulse -o pulse -M M17:3:SP5WWP:BROADCAST:48000`
Using the `-8` option (raw audio monitor) will instead send encoded raw audio to output instead of decoded audio. For example,
To send a voice stream out of stdout into SOCAT TCP to a second/remote DSD-FME session to decode:
Encode (Upper Z):
`dsd-fme -fZ -8 -i pulse -M M17:9:LWVMOBILE:DSD-FME:48000 -o - | socat stdio tcp-listen:7355,forever,reuseaddr`
Decode (Lower z):
`dsd-fme -fz -i tcp:192.168.7.8:7355`
NOTE: When using tcp input for M17 decoding, DSD-FME will keep the TCP connection alive with constant retries, so no need to restart the decoding session on connection failure.
SMS Packet Encoder (Text Only):
`dsd-fme -fP -8 -S "This is a sample message sent over M17 Packet Data using DSD-FME to encode it."`
SMS Packet Encoder (over SOCAT TCP):
`dsd-fme -fP -8 -S "This is a sample message sent over M17 Packet Data using DSD-FME to encode it and SOCAT to send it over TCP." -o - | socat stdio tcp-listen:7355,forever,reuseaddr`
Many combinations of input and output can be used as well, and using features like raw audio saving with `-6 m17str.wav` will save a wav file of your encoded audio to be replayed later with `-i m17str.wav`
Also note, features function similarly, like -Z for payload, and input options include pulse, oss, stdin, rtl, tcp, etc, using those as the mic in for voice encoding. With the right setup of input/output/input using SOCAT TCP pipes, it is conceivable to use DSD-FME to convert analog audio from NFM into M17 audio, or even change another digital format supported by DSD-FME into M17 audio, if desired (purely for research and fun purposes). Ncurses terminal will function with internal encoder/decoder and wav file creation, with toggle encode/tx with `\` key, but will not function with stdout properly.
The `-M` switch is used to specify user M17 variables, the string is in the format of M17:CAN:SRC:DST:INPUT_RATE.
CAN 1-15; SRC and DST have to be no more than 9 UPPER base40 characters.
BASE40: ' ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-/.'
Input Rate Default is 48000; Use Multiples of 8000 up to 48000.
Values not entered into the M17: string are set to default values. M17:7:DSD-FME:DSD-FME:48000
Fun Example Transmuting OTA Analog Things into M17:
Start up in sequence.
Terminal #1 (RTL Input):
`dsd-fme -fZ -8 -M M17:1:ANALOG:M17:48000 -i rtl:0:162.425M -o - | socat stdio tcp-listen:7310,forever,reuseaddr`
Terminal #2:
`dsd-fme -fz -i tcp:127.0.0.1:7310`
Fun Example Transmuting OTA Digital Things into M17:
Start up all three of these in sequence.
Terminal #1 (connecting to SDR++):

## How to clone and build this branch
### Ubuntu 22.04/20.04/LM20/Debian Bullseye:
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 23.04 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/audio_work/download-and-install.sh
sh download-and-install.sh
```
### Debian 12 (SID) / Ubuntu 24.04 LTS (Updated Ncurses Dependencies)
```
wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/audio_work/download-and-install-ubuntu2404lts.sh
sh download-and-install-ubuntu2404lts.sh
```
### Arch Based Distros:
```
wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/audio_work/download-and-install-Arch.sh
sh download-and-install-Arch.sh
```
### Other:
If you have dependencies already installed, please run this instead:
```
wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/audio_work/download-and-install-nodeps.sh
sh download-and-install-nodeps.sh
```
## 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.
Debian/Mint/Ubuntu/Pi
```
sudo apt update
#Ubuntu 22.04 lts / Debian 11 and lower
sudo apt install libpulse-dev pavucontrol libsndfile1-dev libfftw3-dev liblapack-dev socat libusb-1.0-0-dev libncurses5 libncurses5-dev rtl-sdr librtlsdr-dev libusb-1.0-0-dev cmake git wget make build-essential libcodec2-dev
#Ubuntu 24.04 lts / Debian 12
#sudo apt install libpulse-dev pavucontrol libsndfile1-dev libfftw3-dev liblapack-dev socat libusb-1.0-0-dev rtl-sdr librtlsdr-dev libusb-1.0-0-dev cmake git wget make build-essential libncurses-dev libncurses6 libcodec2-dev
```
Fedora 36/37 -- from https://github.com/lwvmobile/dsd-fme/issues/99
```
sudo dnf update
sudo dnf install libsndfile-devel fftw-devel lapack-devel rtl-sdr-devel pulseaudio-libs-devel libusb-devel cmake git ncurses ncurses-devel gcc wget pavucontrol gcc-c++ codec2-devel
```
Arch -- https://github.com/lwvmobile/dsd-fme/issues/153 and https://github.com/lwvmobile/dsd-fme/issues/153
```
sudo pacman -Syu
sudo pacman -S libpulse cmake ncurses lapack perl fftw rtl-sdr codec2 base-devel libsndfile git wget rtl-sdr
```
## Headless Ubuntu Server/Pi
If running headless, swap out pavucontrol for pulsemixer, and also install pulseaudio as well. Attempting to install pavucontrol in a headless environment may attempt to install a minimal desktop environment. Note: Default behavior of pulseaudio in a headless environment may be to be muted, so check by opening pulsemixer and unmuting and routing audio appropriately.
```
sudo apt install libpulse-dev libsndfile1-dev libfftw3-dev liblapack-dev socat libusb-1.0-0-dev libncurses5 libncurses5-dev rtl-sdr librtlsdr-dev libusb-1.0-0-dev cmake git wget make build-essential libncursesw5-dev pulsemixer pulseaudio libcodec2-dev
```
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")
```
git clone https://github.com/lwvmobile/mbelib
git checkout ambe_tones
cd mbelib
mkdir build
cd build
cmake ..
make -j `nproc`
sudo make install
sudo ldconfig
cd ..
cd ..
```
Finish by running these steps to clone and build DSD-FME.
```
git clone https://github.com/lwvmobile/dsd-fme
cd dsd-fme
mkdir build
cd build
cmake ..
make -j `nproc`
sudo make install
sudo ldconfig
```
### LD_PATH
Some environments may require an LD path to be set to /usr/local/lib, similar to:
```
LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH
```
### Windows Cygwin Builds
Cygwin builds now have an experimental semi-automatic installer, to run, follow steps below:
Open Windows PowerShell (not Command Prompt) and copy and paste all of this in all at once.
```
Invoke-WebRequest https://cygwin.com/setup-x86_64.exe -OutFile setup-x86_64.exe
.\setup-x86_64.exe --packages nano,libpulse-devel,libpulse-mainloop-glib0,libpulse-simple0,libpulse0,pulseaudio,pulseaudio-debuginfo,pulseaudio-equalizer,pulseaudio-module-x11,pulseaudio-module-zeroconf,pulseaudio-utils,sox-fmt-pulseaudio,libusb0,libusb1.0,libusb1.0-debuginfo,libusb1.0-devel,libncurses++w10,libncurses-devel,libncursesw10,ncurses,cmake,gcc-core,gcc-debuginfo,gcc-objc,git,make,socat,sox,sox-fmt-ao,zip,unzip,wget,gcc-g++,libsndfile-devel
```
Pick a Mirror. http://www.gtlib.gatech.edu mirror seems relatively fast. Nurse the Cygwin installer by clicking next and waiting for it to finish. Ignore the warning popup telling you to install libusb from sourceforge. Install the [Zadig](https://zadig.akeo.ie/ "Zadig") driver instead, if you haven't already and have an RTL Dongle. After Cygwin finishes installing, the installer sh script will download and run, be patient, it may also take a little while.
Then:
```
C:\cygwin64\bin\mintty.exe /bin/bash -l -c "wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/refs/heads/audio_work/download-and-install-cygwin.sh; sh download-and-install-cygwin.sh; dsd-fme;"
```
After the sh script finishes, dsd-fme should open. If not, then double click on the Cygwin Terminal desktop shortcut, and try running `dsd-fme`. If you chose to create a portable version, you will find the folder and zip file in the `C:\cygwin64\home\username` directory if using the default cygwin64 folder location.
You can also update your versions by using the cyg_rebuild.sh script `sh cyg_rebuild.sh`.
### Virtual Sinks
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. Note: This setup is completely optional if using TCP Network Sink Audio and/or RTL Input. You may need to manually install either of these programs manually, if desired, or find suitable alternatives for pipewire-pulse such as pwvucontrol, or similar.
```
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
```
### Applying Patches -- Recommended For Advanced Users Only
More experimental or potentially functionality changing or temperamental features may be included as seperate .patch files inside of the patch folder, and are not included in the source code by default.
If users wish to try or use these patches, then they can apply patches and build/rebuild with the following procedure. Make sure you have changed to the dsd-fme directory first, either by the top
command, or by otherwise opening the terminal to the clone folder.
```
cd dsd-fme
git apply patch/patchname.patch
cd build
make
sudo make install
```
If you later wish to update to the latest version via `git pull`, you may first need to reset any patches, perform the `git pull`, and then reapply patches.
A procedure for this is similar to, but not limited to:
```
cd dsd-fme
git reset --hard
git pull
git apply patch/xyz.patch
cd build
make
sudo make install
```
NOTE: Patches can potential break over time with further changes to code, requiring merge resolution or other manual intervention to re-apply patches.

-fE -i rtl:0:850M:44:-2:24 -T -C edacs_channel_map.csv -G group.csv -N
Scanning Option Examples:
Scanning will not perform quickly like a real scanner, but can be used with any
supported decoding type and analog as well, and will require a channel_map to scan frequencies
channel numbers do not matter, but use unique ones for each frequeny
-t 0 will scan as fast as possible, but may miss frame sync, -t 1 is stable, but needs 1 second between tuning

#Notes: parameters after -i tcp can be omitted if using localhost as the default hostname to connect
#and 7355 as the default port number. -U is the port number for RIGCTL and will mirror the tcp hostname
#running under the assumption that the user will be connnecting the VFO to the same instance of SDR++
#You can also specify an ip address to connect to a remote SDR++ instance, make sure that the settings
#inside of SDR++ match, i.e., change in SDR++ from 'localhost' to an IP to bind to (machine's IP address)
#Note2: RTL input should only be used on strong signal, the SDR++ VFO will perform much better on marginal signal
#paramters after -i rtl can also be omitted now if using the default configurations
#Having a -G group.csv is purely optional, but useful if you want to block groups, or give groups names
