Eliminate Telephone RF Interference
Have you ever been talking on the phone only to have another unwanted
voice come in over the line, interfering with your call and making it nearly
impossible to carry on your conversation. This type of interference is
caused from a number of sources, including CB operators, Police Radios,
Ham Radio, and even Commercial Standard Broadcast Radio or TV. This is
called Radio Frequency Interference or RFI.
Considering how difficult it is to have a telephone conversation when RFI
is present, just imagine the havoc that this would cause for your FAX or
computer modem. You need to protect yourself against this kind of intimidation.
Don't worry. There is a way to eliminate RF Interference. Use a Sparrevohn
Engineering foneFilter. The foneFilter is connected to your telephone and
then allows only the normal Voice Frequencies to get through to the telephone.
All other frequencies are filtered out.

it, order a foneFilter from:
