AW: [30MDG] PSK ?
- Bpsk shifts phase between 0 and 180 and back
Qpsk knows also 90 and 270 degrees in the phase switching ... that is why it
is sideband sensitive
Ps most what you will find is bpsk31 (almost standard) and some bpsk63
I never found a qpsk station on air ... I think some use it after asking
qsp-partner to switch ... but do not know really
