PSK63

Spectrogram with PSK63 signal surrounded by several PSK31 signals

PSK63 ( Phase Shift Keying , 63 Baud ) is a data transmission protocol for radio links.

The protocol is mainly used in amateur radio . Compared to the PSK31 operating mode , it has twice the baud rate , but also requires twice the bandwidth. Like PSK31, PSK63 can be operated either as binary phase shift keying ( BPSK ) with two or as quadrature phase shift keying ( QPSK ) with four phase positions , which doubles the channel capacity if the signal-to-noise ratio is sufficient .

With QPSK, the sideband must match at the transmitter and receiver, with BPSK not.
