Noisy electrical circuit?
 

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!

I'd tend to say it may be noise generated from a computer or other nearby
electronic gear.
If he can still hear it then he should be able to start shutting down
electronic devices one at a time and see if it goes away.

Possibly dimmer switches on his lights.

Sounds like a CATV leakage detection signal. If he can hear that, some
nearby CATV wiring/connectors are leaking RF.

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.

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