I have a problem with hum on some of my telephones. This is probably caused by too long horizontal runs of unshielded "satin" cable (line cord). (I use that' instead of twisted pair since it is easier to install). 60hz is supposed to be outside the audible portion of the phone "spectrum", so can I get a filter (ready-made or I'll build it) to take care of this problem, or should I bite the bullet and rewire?
