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.

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
There is a tutorial on power and grounding for ham radio in this link.
Details of power distribution are specific to North America, but the
same principles apply inside our homes and shacks are the same worldwide.

I had a similar issue, the fix was a cheap ground loop isolation
transformer cable.

Sometimes, when signals are strong, I receive signal with 100hz spacing.
Thanks in advance
Hi Costy,
spurious images of signals spaced at two times the line frequency are
due to mixing with PSU
