Hi Mark,
Your example *.wav files suggest something seriously going wrong in your
data acquisition chain. It's unlikely that long-distance attempts at
diagnosis can be successful; you'll need to do some sleuthing on your own.

Hi Joe,
I've been back through my saved files and picked out a few that
demonstrate what I'm randomly seeing, attached to this email. I'd be
interested to know if they reveal anything at all, including a possible
intermittent problem with my system. Unfortunately I can't identify the
exact software version for each one; it will have been a recent dev
build (I suspect v1.8.0-rc2 r7924), but it's somewhat irrelevant because
this particular problem has been quite persistent through versions.
Regards, Mark

I'm currently trying to capture some examples where the WSJT-X
waterfall appears to become corrupt with multiple images of signals,
along with multiple decodes - I see this fairly frequently when using
FT8, and have also seen it very rarely with JT65, including on older
versions of WSJT-X (e.g. the 1.7 release)
I have never seen an example of multiple images of a signal
attributable to any corruption of the waterfall. If you see such an
effect frequently when using FT8, it should be easy to capture an
example while saving the .wav files, and send us one or two .wav files
for analysis.
