Ive done some keyboard to keyboard BPSK63, and its much like BPSK31, except a whole lot faster. HI. Not much difference, that way, unless each of you are using MACROS, and the info comes across so much faster. I personally try to type most of my QSOs to design them toward the guy I am working. Most really arent interested in my 100 watts, 3 el yagi at 30 ft. blah blah blah. Even the home brew computer doesnt elicit much comment these days. Its odd to try to converse with some DX stations, and watch their MACROS come across, the same to every contact they make. I would rather they try English, while I try my Greek , Italian, orSpanish on them (if that is what they speak). Danny Douglas N7DC ex WN5QMX ET2US WA5UKR ET3USA SV0WPP VS6DD N7DC/YV5 G5CTB
All 2 years or more (except Novice) Pls QSL direct, buro, or LOTW preferred, I Do not use, but as a courtesy do upload to eQSL for those who do.

(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).
