[1000mp] MP RFI Sensitivity

[Steve L.]

I have a MP Mark V and under certain conditions it
will get a rough monitor tone (CW) but the output
signal is clean.

When the monitor gets REALLY rough, the output signal
is also distorted/modulated/nasty.

This happens when I use an off-center-fed antenna, fed
with 'balanced' feedline and RF is getting into the
shack via radiation. No grounding would ever affect
it.

This is the only radio I've ever had that was RFI
sensitive. When QRO on 10m, I've had it reset the
rig's CPU suddenly. The thing has a ferrite clamp on
every I/O: key, RS232, headphone, linear relay, etc.

I've since been forced to change my antennas due to
this problem. I use wire arrays with tall trees for
support.
