Walking around with a portable AM radio is a good way to track down
power line or circuit interference.

First thing to do is shut off the main power to the house at the box. If the
noise goes away, it's something plugged into AC inside the house that's
creating electrical noise hash. Start isolating which circuit it's on by
throwing individual breakers back on until the noise comes back.

It could also be a piece of power line hardware going bad within several
blocks of your location. Weak power line transformers can create all kinds
of noise hash and still conduct electricity just fine for years. Eventually
they give up the ghost, but it's next to impossible to convince a power
company to fix this problem until it actually blows.

A friend of mine heard this on his FM radio at about 88Mhz. It sounds like
a noisy electrical circuit to me, but I am no expert. Just wondering if
anyone could confirm this? Forgive the dumb question. Thanks!
