Hi there, I've noticed that my GSM phone creates a noise through my
speakers sometimes (ie when the phone is communicating with the
mothership). No, I don't want to know how to stop it from happening,
I'm wondering what the limits of this interference are ? Is there some
device I can use or create to make more than a series of clicks come
through the speaker ?

I'm a novice, so please type slowly. Any assistance / links would be
appreciated.

Luke

** A CB radio transmitter often does a pretty good job.

27MHz or UHF will break into audio gear if the signal is strong enough.

Boy howdy! It can be quite a startle when some ahole with a big rf amp on
his CB radio drives by while you're listening to a nice quiet passage of
Beethoven or Nirvana.
