Several of us have been working with M17 for the past week, using the Mvoice linux client, and it's working quite well with the reflectors they have in place today.
The number of reflectors have increased from 3 early last week to 9 as of this morning, with a couple more that should show up today. Since it uses the Dstar concept for reflectors, each one can support modules A-Z, so 26 different sets of qso's if it ever gets that busy. 😊 I am greatly looking forward to seeing the TR-9 radio on the air before too long, to really exercise the mode, as the MMDVM and hotspot code gets updated by Jonathan. Once the gateway option is available, then cross-modes of DMR/Fusion etc.. to M17 should will ramp things up until more radios are available. It's really exciting for me to see yet another opportunity for David's Codec2 to truly shine for us. M17 is another great victory for the Open Source World!

Suggesting in 48 bits for Src and Dest, packing the characters as RT11 filenames used to do. (Digital PDP-11 of 1975) What I notice in our HF mode 700D, it has quite poor data reliability particularly in the "Txt MSG" which is where the Src and Dest data may well be. Adding 96 bits to every frame is in my view way too many bits. In our current modes eg. 700D, could we sacrifice every tenth frame for source and destination? Thoughts? --------------------------------------------------- Alan VK2ZIW Before the Big Bang, God, Sela.
