Rick,
Conditions were excellent for weak signal testing.
MT63-1000 was not printable by the time the band had started going out. Olivia
16/500 proved to be the best. We tried DominoEX 4 (about the same wpm as Olivia
16/500), but copy was not as good as Olivia. We then tried DominoEX 8 with FEC,
and copy still not as good as Olivia.
Looks like Olivia is still the best with MFSK16 a close second, but need more
tests between Olivia and MFSK16 to be sure.
Thanks Tony for sticking with me for some very interesting comparisons! I think
the popularity of Olivia is deserved because it does keep printing during deep
QSB.

Tony,
You have done the tests and found that MT-63 is not very good at
handling weak signals compared with other modes. Is you recent on air
testing to determine that or some other parameters, such as ability to
handle interference, etc.?
By the way copying both you near noise level, and Skip, KH6TY, a bit
stronger at S3-4. Tried to decode an earlier narrower mode but no luck.
Was it MFSK8?

Your signal is in the noise. Hope the band changes...
