Just shows what an excellent engineer Pawel is (Pawel designed Olivia and MT63
and had a part to play in PSK with slowbpsk).
Also I would have sent the PSK using lowercase - it's faster, less bits per
character and hence more robust.

PSK lowercase will be interesting, as *everyone* on this list knows lowercase
PSK is faster and more robust, yet many Hams send everything in uppercase -
calling CQ DX in uppercase is just - daft :)
FWIW The only difference between Contestia / RTTYM and Olivia is that Olivia is
a 7-bit char

the same wpm rate as Contestia 16/500,
but Contestia is some 6db more robust.

All,
Thought this might interest the group
The path simulation tests below show how each mode might behave under the same
signal-to-noise / HF path conditions.
Modes included in each test group have approximately the same word-per-minute
rate -- for example: Olivia 16/500, RTTYM 64/500
Time to start using Contestia again ?
Maybe no need - cycle 24 has started now :)
