I have been spending quite a bit of time over the last 2 to 3 years
using and helping with the development of FreeDV digital voice
including the current RADEV1 Radio Auto Encoder machine-learning neural speech codec. I am a member of the project leadership team, the project
is funded by an ARDC grant and has a few people involved who really have
a brain the size of the planet.
FreeDV is making quite a stir and the global usage is increasing quite rapidly. Anyone else here interested or indeed already a user?

I hope it sounds nicer than the current AMBE2 or whatever it's called
that everyone is using for DMR Maybe it does even sound like Marvin.
BTW, was that a grant that was funded by the flogging off a large chunk
of 44/8?

I got an NOV for 146MHz quite a few years back 2014 and tried FreeDV
with a few locals. I didn't really get it to work properly. It
sounded like a bad mobile phone signal. It's possibly my computer
wasn't up to it.
I may re-visit it and have a listen.

The thing is, the PSK modulation on the sub-carriers is actually
analogue for the RADEV1 mode, it's effectively a black box so there is
no way to determine what the ML and neural network thinks the
constellation points are.

The current FreeDV 2.x using the RADEV1 machine-learning neural net
codec is vastly superior to the Codec2-based version 1.x that you would
have been using previously.
I thoroughly recommend trying it, there has been a lot of work on the
GUI software as well.
Yesterday I downloaded the latest version of FreeDV (2.0.1 with the
RADE modem) and was trying it out today.

The latest released version is actually 2.1.0 so make sure you have
that and not the version you typed.
