don't forget about SW...and it doesn't have to be close at all. We found
some interference from a SW station hundreds of miles away getting into
a Micor receiver. Turns out the SW station was several Khz away from the
high IF freq of the receiver (11.7, don't remember the freq of the SW
station). Putting a better ground on the chassis, to the building
sprinkler pipe, got rid of it.
