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.

experiencing some radio interference and linked this to the MRX: the
radio gives white-noise static -- like the squelch is not properly
adusted. When I turn the MRX off it goes away.

I've heard putting a "ferrite core" around the MRX's (and the
radio's?) power cord might help. *(Here's one:http://cgi.ebay.ca/Noise-Filter-Clip...QQitemZ3501565...
On the previous model I did wrap several turns on the bead. Only
sending it in fixed the problem.
On this one, I'm not wasting my time. I'm awaiting my rma # as I
write.
Seems to me whatever power supply, or downstream component, design
they used before is the same now.

Does anybody else have this problem? *Have you solved it in some way?


Make sure you are installing a large enough ferrite bead (beads is
slang, fat walled cylinders might be a better description) that allows
the power cable to go through the middle and be wrapped around the
outside several times. Use a thin gauge wire cable to help with this
and the bead can still be small and allow you to feed the cable
through several times. It may be worth trying to installing this close
to the Zaon end of the power cable if it does not work elsewhere.
