Project M17 Digital Radio

 

I have been playing with  M17 using both my own software and a modified 

TYT MD-UV380 DMR handheld running OpenRTX software. OpenRTX

now supports transmit and receive.

 

The top video is a quick test over QO-100 using my software for transmit

and SDR++ for receive. The middle is my software receiving M17 from

a handheld. The final is my first tests using a Raspberry PI4 and LimeSDR

running my software.

 

I have released my implementation of M17 on Github, if anyone wants to

play with it, they will need to go into the Release directory and do a make. 

They will have to already have the development packages for LimeSuite, 

Codec2 and ncurses installed on their machine. 

 

It runs in a console and typing h will give you the list of commands. 

There is no network support yet, so you won't be able to join 

a reflector. It is just proof of concept. The code is very dirty and could 

do with a good tidy up.

I am now considering what I should do next with the project. I am not a DStar,

DMR or Fusion user, so am totally clueless.

 

I wanted to run it on a much smaller CPU but due to the chip shortage

getting anything at the moment is problematic.
