I've had an "Invisible Fence" system in place for over 4 years without
any RFI problems (either RX or TX). I *have* had problems with ColorTV
horiz circuits.... Our dog's ("Q") kennel was in the next room adjacent
to where we had a Sony 35". The first time we turned on the set AND had
the dog in the kennel was a real hoot. Took over a week to get "Q" back
into the kennel.

If it is the original Invisible Fence, they operate at either of two
frequencies, 7.5 kHz or 10.7 kHz. The modulation is at 30 hZ.
A contact name that I have at the factory is Jennifer Walsh and her
e-mail
address is: jwalsh@invisiblefence.net
Jennifer did mention to me in an inquiry that I had, "There is a slight
possiblity of your radio operations
and the Invisible Fencing system reacting to each other -- especially
if
you are sending code transmission. We stand behind our product with
money-back and containment guarantees. Your local Dealer can explain
these
programs."
I have been thinking of installing one of these myself and am very
curious
what you find out Fred.
