-## 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 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.
