Ham Expo presentation from September 2022 by Paul Williamson, KB5MU.
Transmitted voice can never be perfect. Some amateur radio voice modes, especially digital ones, are very much less than perfect. We propose and demonstrate a prototype of Opulent Voice, a higher bit rate digital voice mode that brings voice quality up to a new level.

Ham Expo presentation from September 2022 by Paul Williamson, KB5MU
Satellite communications systems are subject to a broad range of potential abuses. As satellite communications systems become more useful, they can even attract pirate users from outside the intended community. We propose a system for P4XT that securely authenticates every user on the uplink of a digital system in real time, so that the satellite owner's authorization policy can be enforced.
