I use an ICOM IC- R10.
The rubber duck antenna that comes with it is pretty useless for power line
noise. (It would probably be fine for walking around an electronics
I have a 2 meter 5/8 wave antenna with a gutter mount attached to the rear
rack on an old bicycle. This gives enough antenna to be reasonably sensitive
on HF through 2 meters.
When I get close enough to hear the noise on 2 meters (typically over a
distance of +/- 5 to 10 poles) I switch to a small (6L) 432 yagi with which I
track it to the individual pole.
The bike works well, as it is easier to stop alongside the road, or change
directions. Also you don't have ignition noise from your own car to deal with.
OTOH it is not so good during the winter months here in Ohio.
I also take along a digital camera. In cases when there is a visual defect
(broken insulator, visible arc, etc.) it is good to be able to send a photo
to the local power company guy showing him that a problem really does exist.
