A major consideration of the various Olivia modes on the lower bands is baud rate. If you have good conditions, the 62.5 baud rate should be OK much of the time, however it is somewhat above the 45 baud rate that was experimentally determined to be a cut off point with some ionospheric condx.
I have used the 500/8 (62.5 baud) but had some difficulties under difficult night time condx on 80 meters. I think you will find that the 1000/16 (62.5 baud) won't work much better under those condx either, but the 32/1000 (31.25 baud) does better. Has anyone found that the performance of the (much wider) 1000/32 mode is all that much better than MFSK16 which is only 1/3 as wide? I always seemed to have good luck with MFSK16 and also found the throughput much better since it is around 40 wpm compared to Olivia 500/8 at just under 30 wpm and Olivia 1000/32 at only ~24 wpm. But you just don't hear much MFSK16 anymore as most have moved to Oliva for now. 73, Rick, KV9U John Bradley wrote: > I'm with Bill: the standard could be 500/8 , but the difference > between 500/8 and 1000/32 under poor conditions on 80M has to be seen > to be believed. > > If we confine ourselves to either 500/8 or 1000/32, and even 250/4 > then it's easy to tell what the mode setting are by the bandwidth > > John > VE5MU Need a Digital mode QSO?
