[RFI] RFI into A/C condenser

[kd4e]

Jim has, as usual, nailed the remedial methods.

Other Questions:

Have you looked at your antenna system to be sure it is
not radiating lots of harmonics?

Have you considered relocating your antennas, or if a
fixed wire antenna moving a leg of it that may be parallel
to or terminating near to the A/C unit/wiring?

What sort of power levels are you running and on what
bands?

> choke. There may also be power wiring problems in the air
>  conditioning system.
