New Digital Voice Mode FDMDVA new Digital Voice mode FDMDV has been announced on the N1SU.com website. It claims to be able to require a bandwidth of only 1.1 kHz. The website says: "FDMDV is the latest digital voice mode on HF - it caters to high quality digital voice under poor band conditions, in only 1100Hz bandwidth !" Personally I feel the words "high quality" may overstate it. Traditionally there has been a trade-off between bandwidth and quality, the less bandwidth the worse the quality. But it's free and costs nothing to try so I'm downloading my copy and if it comes anywhere close to the quality of a 2.4 kHz SSB transmission then I'll be more than happy
