• Anyone doing anything radio-related these days?

    From Brian Morrison@3:633/10 to All on Tuesday, November 25, 2025 13:49:48

    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 would like to congratulate you and the whole team for a huge and difficult, but essential, achievement. If I get round to any activity I'll certainly give it a try.

    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.

    I don't know the source of the funds, only that we applied for a grant
    a couple of years ago and received it.

    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.

    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.

    Yesterday I downloaded the latest version of FreeDV (2.0.1 with the RADE modem) and was trying it out today.

    Very Impressive! Very good audio quality and a very sensitive decoder.

    Bit fiddly to set up - I'm using an Icom 7300 with comms/control via the Icom's USB Interface. Once I got that sorted and working, operationally
    it is all very straightforward.

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