Had a good read.? I can add that Jonathan Naylor G4KLX was responsible for adding M17 support to the MMDVM project (which is also his work).? He also created M17Client, which is client side (radio terminal) software that used a MMDVM board as a user radio.? This works with both the modems (paired with a 9600 capable radio, makes an excellent M17 radio) and hotspots (creating a QRP self contained transceiver).? Only other thing required is a USB sound device and some form of display usually HDMI or Nextion, though I got it working using a remote X server.

I've been involved in testing the MMDVM implementations of M17.? I've also played with the TNC3 (unfortunately the app doesn't like my Android phone, which makes it a challenge to get working reliably), and today I use a Module17 into my own local M17 systems.? The M17Client is still available as an alternative or for demonstrating a different implementation.? As your article states, the different implementations work well with each other.

You missed M17Tools, which is a suite of software that runs on a host PC/Pi/Mac etc and can use a soundcard interface (Digirig is a recommended all in one interface that can pass baseband) to do M17 with a 9600 capable radio.? At this time, M17Client doesn't like my Windows laptop, but others have reported good results, especially on Linux hosts.

Haven't got my hands on a CSI radio yet.? Unfortunately, current exchange rates and other issues make it a lower priority expense right now, but I'd like to eventually support their efforts, because it deserves support.? Yes, it's at an early alpha level, but testing and bug reporting is an interesting and worthwhile activity for me to do.
