Alex - good idea for using the waterfall display for just that. Thanks
I have a few other suggestions that I will try the next dx split RTTY
operation

Thank you to everyone who shared their pileup cracking techniques with
the group. I do not have a second receiver in my radio, so until I
find a better method (or write better software), I just use a
SoftRock-based waterfall display to find the frequency where the DX OP
is listening. I look for a signal trace that starts right after the
end of the RST message sent by DX. Usually there is more than one such
message, so I also look at the trace end, it should align with the
start of DX's "TU-QRZ" message. If there are still multiple signals
that match both requirements, the final test is to check that the
signal disappears after the end of the QSO. If it is still there after
"TU-QRZ", then this is an out-of-turn caller and not the one who was
in the QSO.
This method is not ideal, I am able to find the DX listening frequency
in about 1 QSO out of 5, while in CW I know the right frequency in 90%
cases (I just read Morse code off the waterfall). Despite its modest
efficiency, this method helped me to work in RTTY all recent
expeditions that I was able to hear, except K5P. I used the waterfall
display in CW Skimmer just because I was used to it, I believe any
other waterfall would work.
