Check the wiring on the mic cable. If it is a Heil cable, the MIC- and
ground may be bonded (connected) together (they should not be connected)
and the ground/cable shield may not be connected to the shell of the
8-pin Foster connector (which it should).
Then try a ferrite bead on the mic cable.

Some more info.
Antenna is Butternut HF6V mounted on the barn using the metal roof as a
counterpoise.
Mic is Heil HM-5
I have a ground strap from my FLEX to the PSU on my computer and also ground to
a copper plate buried outside the barn. The grounding system in Norway is very
bad.

You will need to describe more of your setup. Antennas, grounds, type of mics,
etc.
If you have a ground on the radio, try removing it and see if it clears up.
RFI issues require a lot of trial and error testing. It is not a fault of the
radio unfortunately.

I have had my FLEX-5000A for a couple of months now, and I love it. Get great
reports on audio on all bands, (haven't tested 6 meter yet, since I don't have
an antenna for this band), but on 10 meter they complain about really bad RF in
the audio. What can be the cause, and what can I do about it?
