 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
 80 meters with a neighbor, although it took 2 filters in series to do the

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.
