Hi Eugene,

Are you using a switch-mode power supply
to feed the KAT500?  If so, try a linear regulator
supply or a battery instead.

Is your KAT500 bonded to your other station
equipment and AC ground with a short, wide
conductor? (not just the coax shields)

Since you're not the original constructor of
the KAT500, I would check inside the case
to be sure that the case sections have the
powder coat removed where circuit board
standoffs and case section screws are placed.

What kind of cable do you use to connect
the KAT500 to your shack computer?  One
should NOT use a standard VGA cable as
the manual makes clear.

73,
Mike, K8CN
