FreeDV - Open Source HF Digital Voice for Amateur Radio
“FreeDV is a suite of digital voice modes for HF radio. Our flagship mode is the Radio Autoencoder (RADE). You can run RADE using a free GUI application for Windows, Linux and OSX that allows any SSB radio to be used for high quality digital voice. FreeDV technology is being developed by an international team of radio amateurs working together on Machine Learning, DSP, coding, design, user interface and testing.”
It's true that amateur radio has been constantly evolving over the years. A lot has been happening with digital text based messaging, and just a few watts of power is easily transversing 10,000+ kms between continents.
Voice took a big leap forward with SSB when it came out, and with many clinging to that because they want to “talk” to others, it looks like FreeDV will offer that same experience, whilst utilising all the advantages that a digital mode can offer.
Apart from being able to use less power, the other plus of digital modes, is punching through the ever-growing noise floors that are killing some voice/phone bands.
Best of all, unlike the VaraHF and VaraFM protocols, this is an open source protocol.
