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.
