[RFI] DSL RFI Problem Solved

[Larry Benko]

I take that to mean a snap on core with an inside diameter large enough 
for RG-8 coax made from type "F" material.  Type "F" material is a 
medium to low frequency material having a permeability of ~3000.  It is 
similar to 77 material if that helps.  I agree with the comment Jim made 
about using #31 material (u ~= 1500) with many turns.

Type "F" material has been around a long time and believe it was first 
made by either Indiana General or Arnold.  Someone correct me if that is 
wrong.
