Not sure it's any help, but I used to have a very similar problem but
it only happend on a few channels.  Came to find out that those
channels also happened to be on the same frequency as my Verizon LTE
phone... every time I had my phone in my office with me, I would have
damaged recordings on my prime.  The same channels were unaffected on
my standard HDHR... which suggests that the Prime is more susceptible
to interference.

I made a tinfoil faraday cage for my Prime and haven't seen the issue since.
