Info on Interference From "Hidden Fence"

Several members have reported interference from a new product called the 
"Hidden Fence." This product uses a VLF transmitter, a large perimeter 
loop, a receiver on a dog collar and a shock device to help teach a dog 
to remain within your property lines. 

Earlier versions of this were marketed without FCC approval and may 
generate interference to much of the HF band. The interference is 
characterized by a pulsing harmonic (like CW dits) every 35 kHz or so. I 
contacted the Hidden Fence Company and was told that a "suppressor kit" 
is available free of charge. When you call, it is a good idea to ask 
for "Cheri" because others may not know about the suppressor kit.

The ARRL RFI desk (that's me!) is looking for any report from someone 
who can verify that this suppressor kit is effective. Contact me here at 
HQ by phone, letter or email (ehare@arrl.org).
