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. This project wouldn't be possible without a few good people providing me plenty of sample audio files to run over and over again.

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.

## 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 Furthermore, any wiki articles with 'auto intstall scripts' made for windows users may contain outdated information for building the deleted pulseaudio branch, please adjust any information found in those accordingly.

## 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.

Currently uncoded/unknown DMR trunking systems include Hytera XPT. 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.
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. 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.
