Allister Watson GM7RYR, who is beacon-keeper for GB7EE, talked about Digital Voice Modes at the meeting on 28th Feb 2018 at the Braid Hills Hotel. 

This talk looked at the different digital modes used on the VHF / UHF bands: D-Star, Fusion (C4FM) and DMR, the developments of the Local, National and International Networks and compared this with the state of the networks at the last talk given to the Lothians RS in February 2016. (Click)
