hear radio broadcast on the phone???interfere modem.

[[email protected]]

I have problem with one of the phone jack on the wall, sometimes i hear
some kind of
radio broadcast on the phone. Even though it's very faint, it interfere
with the the
dial up modem, and cause the connection to stop.
I replace the old jack,but it doesn't solve it.

Another jack on the same line does not have this problem, but the jack
is too far away from
my computer.
I don't even has a radio or walkman or TV in the apartment, so i don't
know how the radio
broadcast got into the phone line.

Any suggestion of how to elimnate the interfernce from the radio?

In such cases it's common to have a simple RF filter on the incoming phone line.
I have one here.

In the UK BT will fit such a filter for you.

It's caused by the signal from the radio station leaking into your
telephones and possibly the lines.

Listen until you hear a station ID, then call the station and ask to
speak to the chief engineer about an interference problem. Be polite
and they will help you fix the problem.

If the audio is intelligible, it is an AM station. Is your home hear one?
If so, the phone company will usually install a filter for no charge.

The funny thing is that i can happen at any time, somtimes it lasts for
the whole day, somtimes just couples hours or even minutes.

Yes, that is possible and likely. Here is what often happens: an
intermittent connection (usually one with some oxidation) is acting like a
rectifier. A rectifier is a detector (demodulator) for amplitude modulated
radio signals. Intermittent joints, splices, or connections can change with
the phase of the moon or the amount of lint in your dryer.

I live a mile from a 5KW AM station and had problems with radio audio in the telephone. My phone
jacks were wired with jacketed two-pair unshielded wires. One of the pairs was unused. It turns out
the unused pair acted as an antenna and fed RF to the phone. The phone rectified the RF and you know
the rest. My solution: ground the unused pairs close to the tie point of your incoming phone line's
terminal block; a cold-water pipe is best. That fixed my interference problem.

Marslee-

The FCC did a study and found that 68 percent of phones tested at that
time, would receive radio interference. I can't find the report, but
did find a summary at:
http://www.fcc.gov/Bureaus/Common_Carrier/News_Releases/1994/nrcc4019.txt

In your case, the problem might be in a phone at another part of the
house that you don't suspect. If not, it is likely to be a problem with
the wiring as others have suggested.
