WMAQ-AM (670 kHz) has their tower in Glendale Heights, IL, next town
from Bloomingdale.  I never had any problems while living in
Bloomingdale, but every time I call my girlfriend in Itasca, IL (about
eight miles from WMAQ) I get WMAQ in the background.  She has two
phones (on the same line).  If both are unhooked for some reason (e.g.
family gettign annoyed over the phone line beig tied up), the
interference gets so powerful I can hear nothing *but* the radio.
When only one phone is off-hook, it is bearable, probably around the
8-10 dB under voice level you mentioned.
