[BC] RF interference problem

[Paul Smith W4KNX]

Run some copper strap to a good common point ground and ground all phone,
electric, CATV to that common point.  My bet is that you have a length of
cable somewhere in your studio that is a perfect multiple wavelength of the
offending signal.  Once you find that, the problem will probably go away.
You can make a stub out of coax to short the signal out.  I agree that the
radio station is probably not at fault, but you might contact their engineer
who may help you solve your problem.  One of my business enterprises is home
intercom systems.  I've had numerous issues with RF getting into these
systems as the wiring in the house is sometimes multiples of the offending
signal.

Good luck and my bet is that the people on this list will have many tips to
help you
