The Amateur Radio Experimenters Group this month has produced a video of the presentation given by David Rowe VK5DGR on his new FreeDV digital voice codec and SM1000 stand alone encoder/decoder unit. The talk is well worth taking a look at if you have any interest in how digital voice modes can be delivered over HF radio.
David talks about his pioneering work and the open source ideals behind it as well as showing the newly released SM1000 Embedded FreeDV encoder/decoder unit that can be used to add digital voice using Codec2 to almost any current amateur tranceiver.
It’s our intention to film more of the club presentations in the future so stay tuned!
