Digital Voice Codecs in Amateur Radio: Compressing Speech for the Airwaves

Following on from last year's Digital Data over HF Radio presentation, in this presentation, Peter Rossini VK2BFF explores the fascinating world of digital voice codecs and how they make modern amateur radio communication possible.
