Tim, that's very interesting. I have a friend who bought a MRX last
summer. While flying with him last fall I noticed that his MRX was
misreading the altitude of the tow plane. He's planning on sending it
in, but what with his problem and now yours I wonder if there was a QC
problem at Zaon last year. Don't get me wrong, I love my unit and I
know several that are performing exactly as they should - but they're
all older units.

I have the same problem. I also had the problem with the previous
model. I did the ferrite bead and it didn't do the job.
I finally sent it in and they replaced the power mosfet and that did
the trick.
I'm about to send this one in for a firmware upgrade and to deal with
this issue. Hopefully the same way.
