Has anyone tried keyboard-to-keyboard connected BPSK63? (I assume that it is connected and not UI, as we are talking about the FRACK option).
Also, am I correct that PAX/PAX2 will run in connected mode? For some reason I thought they were UI-only, but now I cannot tell. I'm interested in these soundcard ARQ modes. --- In digitalradio@yahoogroups.com, "Patrick Lindecker" <f6...@...> wrote: > > Hello Ian, > > Here is some information about PSK Packet. > > Important: in BPSK63 Packet, set the FRACK option at, at least, 8 seconds > (the standard 5 sec is not sufficient). > > 73 > Patrick > > > Coding/Decoding of Packet BPSK1200 and new modes Packet BPSK250 and BPSK63 > The BPSK1200 Packet mode is used for satellite (as LUSAT LO-19 for example) > transmissions in UHF (USB).
