Very interesting.
What simulator are you using?

Assuming that the S/N is constant. In practice the
S/N seems to vary wildly from
Contestia and RTTYM are variants of the character set used with Olivia.
Olivia is 8-bit, Contestia is 7-bit and (I think) RTTYM is 5-bit or 6-bit.

All,
It's interesting to see how the different Olivia mode configurations compare
when put through the HF path simulator.
I ran Contestia through the simulator this evening and these are the results.
Olivia 16/500 is shown for reference.
CONTESTIA 500Hz
Tones BandwidthChar/s
Exactly what I would have expected, nice to see that you get these results.
