RSGB 2018 Convention lecture: FreeDV - Digital Voice for HF and other low SNR channels

Matthew Phillips, G6WPJ

FreeDV is established as the digital mode of choice for voice transmission on HF and other bands with poor signal to noise conditions. FreeDV can provide conversational voice on channels where SSB cannot be clearly heard. This talk presents information on what it is and how amateurs can try it for themselves. Matthew explains the pioneering work on the voice codec used and a new OFDM 'modem'. Also, some insights on the future developments envisaged are presented. A video demonstration is included and a strong emphasis is placed on practical ideas to get going and join in
