Selective Fading SNR -8db >> MFSK16 90% >> Olivia 500/15 100% >> PSK31 65% >> RTTY 45 25%
Although MFSK16 produced 10% errors when Olivia produced no errors, Olivia 16-500 (20 wpm) takes twice as long to send the same information as MFSK16 (42 wpm), so it is exposed to QRM and QSB over a much longer time. If you are only interested in exchanging name, qth, and signal report, Olivia will usually do that better than MFSK16, but for ragchewing, over a longer time period, using IMHO MFSK16 will probably be as good as Olivia without having to wait as long for the text to appear. 73, Skip KH6TY
