AM broadcast radio is a poor choice for hunting power line noise. Best is to
use your yagi antenna at the home station, put it on 10 meters and get a
general heading where the noise is then get on you bicycle with the air band AM
talki and go in the general direction. It won't be very far, walking is
better. With the air band radio you will hear it when very close and can
narrow the field down to a pole or two and that will be close enough when you
report to the power company. It helps to be there when they arrive and give
them a hand. I've found the power company noise tech to be friendly and very
helpful in resolving noise issues around my area. He's got the full range of
gear and knows how to use it. Plus, he's a lineman first and knows how to
climb poles and work on HV lines.

I couldn't agree less... I've been using my car radio to close in on noisy
poles for a decade and more. Tune to the top end of the AM band and drive.
Get close and take a portable radio from there.
The local electric utility's RFI guy wants to do a good job, and has decent
equipment but doesn't know how to use it. Last time he was floundering around
with a receiver set around 100 MHz with a hand-held log periodic that from its
size probably started about 300 MHz.
Next time I see him I'm going to urge one of Mike's RFI courses.
