Most 2 meter hand helds recieve AM in the aircraft band. I use mine at 130MHz
with a home made step switched RF attenuator and a home made 3 el yagi to
track down noise. By switching in the attenuator as you get closer to the
noise one can pinpoint the source. I got fast response from the power company
when I told them the problem was on the left side of a specific high voltage
power line tower. They also were very interested to find out how I found the
trouble.
