How does PSK or Phase Shift Keying actually work? Previously I've explained how Radio-teletype or RTTY works from a technical perspective. There are several other ways of encoding information and today I'm going to look at Phase Shift Keying, or PSK, which I find humorous, because Phase is spelled with a P, but it sounds like an F, which links the FSK and PSK together, but then I've always had a strange sense of humour.
