PSK63

PSK63 (Phase Shift Keying, 63 Baud ) is a data transfer protocol for wireless connections.

The protocol is used mainly in amateur radio use. Compared to the PSK31 mode it has twice the baud rate, but it requires twice the bandwidth. PSK63 PSK31 can be operated as either a Binary Phase Shift Keying (BPSK ) with two or quadrature phase shift keying (QPSK ) with four phase positions, thereby, doubling the channel capacity with sufficient signal-to- noise ratio.

With QPSK, the compliance of the sideband at the transmitter and receiver is required for BPSK not.
