Two general areas to check out--


Corroded, loose, or missing ground connection 

Corroded, or loose other connections.

(That makes up one area)

Noisy carbons.  (Find the protector--where the teloc wires transition
to the house wire.  Unless theprotector is very old, it will have
what appear to be two large brass screws.  You will discover that you
can remove them without changing any thing.  If you remove them and
the radio goes away--the carbons you now have in your hand nead to
be replaced.  Put them back and complain to the telco.
