I have had good success with plain old Radio Shack line filters (about $20
each). I understand these filters are manufactured for Radio Shack by
another company. These eliminated a telephone RFI problem I was having on

I have a number of the filters mentioned above and they worked great! They
are made by K-Com (see add QST8/98 pg. 146). You have more selection and
lower prices if you buy the K-Com version.
Telephone RFI can be tricky. Not only do you need filters, you need to be a
bit of a dective. BTW, I also used the filters on power supply inputs to
answering machines, cordless phones, etc. Seems like they have no problem
handling the current.
