I am with Dick on this one. You have to hear them first before you can
work them -- in any mode. And I have yet to get a whiff of a hint that
there is a signal at the frequencies they are spotted at (on phone or
CW).
I am pretty agnostic on which mode to work them, but I should have a
better chance with PSK31 because of the signal handling properties of
PSK versus non-coherent FSK (about a 10x power difference when you
account for raw BPSK vs non-coherent FSK, and add to that the bandwidth
difference).
This does not even count the operating skills/habits of the op at the
other end -- digging through an RTTY pileup must be murder for the DX
end and I sincerely hope that they'll use narrow IF bandwidths on RTTY
rather than pointing and clicking on the waterfall for RTTY signals.
