- Recently I was talking on the phone to a friend of mine in Long Beach,
- California, and she told me a a repetitve problem she had been having
- on her phone -- whenever she used the phone, she heard a *radio*
- *station* on her phone line. I listened carefully, found that, on the
- other end of the line, I heard the same thing (only when I was talking
- to her), only not as loud. We identified the radio station as KFI
- (640 AM, Los Angeles).
-
- A few weeks later, I found another friend had the same problem, also
- in Los Angeles, but with a different radio station. The latter person
- had just installed a new phone, so perhaps it has something to do with
- a circuit in the phone instrument responding to the radio signal.
-
- I've heard of RF intereference before, but this is ridiculous. It
- reminds me of a fictional story I once read about someone who got a
- tooth filling that picked up radio stations.
-
- Does anyone know why this happens, or what can be done to fix the
- problem (or reproduce it)?

- [Moderator's Note: There are line filters available which will cure
- this problem. The telco has no special responsibility to handle the
- problem as long as the lines are 'clean' when they had them over at
- your premises. Typically newer electronic phones seem to have this
- problem more than older style instruments. If someone is located
- within a mile or so of a radio station transmitter/antenna the problem
- can be more difficult to clear. You might want to check out an article
- which appeared in TELECOM Digest a few years ago: "Praise the Lord and
- Pass the RF Filters" told the story of the fight residents of the
- north side of Hammond, IN had for a long time (maybe still?) with FM
- radio station WYCA whose transmitter facilities are located about
- four blocks away in Burnham, IL. Maybe I will reprint that article if
- there is sufficient interest. PAT]
