I've generally had varying success with an AM broadcast 
radio, but a VHF aircraft radio always lets me walk right up 
to the bad area.

Many Hams today don't realize that the VHF aircraft band is AM, not FM such
as most hand-held Ham VHF radios use. Of course, FM is inherently noise
suppressing, ignoring all amplitude modulation. That makes most Ham
hand-helds useless for this purpose. However, some do receive the 120 MHz
aircraft band with an AM detector. My Icom W32A is one of those. It is
excellent for chasing noise, as Tom notes. The noise tends to be weaker and
not propagate so easily at 120 MHz, so the source is usually much more
clearly defined as you wander around with the radio in hand.
