Next AREG Meeting – “RADE – Machine Learning for HF Speech” by David Rowe VK5DGR

Posted on by

The next AREG meeting will be held on Friday the 21st of March at the Fulham Community Centre – Phelps Court, Fulham.

This month we have a presentation from David Rowe VK5DGR, on the ‘Radio Autoencoder’ (RADE) digital voice mode, which is in active development and available for preview right now in the latest version of FreeDV. RADE combines machine learning techniques with classical DSP to send high quality speech over HF radio at SNRs as low as -2 dB.

Doors open at 7.00pm and the presentations kick off at 7.30. Everyone is welcome to attend. If you’ve never come along to one of our meetings, we’d love to see you there, all guests are welcome. For our remote members, the meeting will be broadcast via Zoom, and the talk will be recorded for later viewing on Youtube.

After the talks we’ll all be given an opportunity to have an eyeball QSO among ourselves whilst enjoying a tea or coffee and a biscuit.
