Adding one K-Com filter to my wife's answer machine killed 90% of my rfi.
Then grounding unused wires in the telephone wiring, and placing ferrite
beads at near center of my house telephone wiring in attic took out the
rest. Only one problem persists: If we make the call, there is no rfi.
But if we receive the call, a small amount can still be heard??!! Good
Luck, Doug
