Try www.sandman.com. Best site I know of for telephone related anything! Also make sure you still have your twisted pair leads twisted all the way up to their terminations and no phone wiring running parallel to power lines, TV & satellite cables, etc. Any place you have to cross other wiring with phone lines, run them perpendicular to each other. Said another way, make sure telephone lines are run with up-to-date Category 3 or better twisted pair wire and cross other wires and cables at 90 degree angles.

I need to do some maintenance on the telephone wiring in my house in order to cure a hum that is now constant on all phones. While I'm at it, I'd like to take appropriate measures to eliminate, or at least reduce the rfi that occurs whenever I operate on 80 or 40 meters with any mode. Which ferrite beads or filtering should I use, and should I place any such devices on the house side of the entry box rather than, or in addition to at the connection point for each phone? The rfi was present before the hum appeared, so I doubt curing the hum will cure the rfi, although it certainly might at least reduce it.
