- The telephone cable at my home pops out of the ground and into
- a box on the external wall. From there a single cable goes into
- the house. I installed two telephones myself, one in the kitchen
- and one in the bedroom. The one in the kitchen full of electrical
- appliances is fine. The one in the bedroom has a terrible humm.
- I tried swapping the handsets and the humm stays with the
- bedroom not with the handset. The only electrical equipment in
- there is two table lamps. I have re-wired the wall outlet three
- times and that has no effect. The strange thing is that some
- days there is no humm at all, other days you can't hear yourself
- speak. I can find nothing wrong with the wiring, the one in the
- kitchen works fine so I haven't got the colors mixed up.
-
- The only thing I can think of is that the cable in
- the wall passes close to a power cable and that the humm is
- pickup which occurs when some appliance in the house is operating.
- My best guess for a suspect is the refrigerator.
-
- So is there any way to filter out a hum on a phone line
- if so what do I have to get?
-
- thanks

- P.S. Oh, I callet the telephone company, for $50 they will send
- someone to LOOK at it, no promise that they will fix it, they say
- they are responsible for the line as far as the house the rest is
- up to me!
