According to the information in the help files from Multipsk: 1200 baud Packet = 1320 wpm
BPSK125 = 148 wpm capital and 204 wpm small letter average speed at about -8 db S/N Of course this assumes that both have good signal strengths and there are no hits. If the PSK125 mode takes a hit it keeps on sending and the receiving station gets errors. If the packet receiving station gets errors, it requires retries and since this mode also requires much greater signal strength to operate, it can easily have zero throughput and time out eventally after many retries. Packet may need something like +8 db S/N to function. This means it is about the same or slightly worse than the OFDM mode used in digital SSTV programs. Anyone else have more real world numbers? 73, Rick, KV9U Walt DuBose wrote: >Here is an interesting question... > >What is the user throughput in WPM or CPS (what you see on your monitor) in >1200 > baud AX.25 and the 190-200 WPM user throughput of PSK125? > >I have send many, many pure SMTP messages using sendmail over AX.25 KISS mode >with a NOS stack. > >I have also worked with HTML message/E-Mail templates and find only a couple >hundred characters different in the template E-Mails/messages and those that >are >full and complete E-Mail such as used by sendmail. > >Walt/K5YFW > >
