John,

Specifically, you cannot get the kind of location detail using a radio that you can with a light probe.  However, 
since you are using a different energy type, you can sometimes get information that you won't get with a light 
detector.  Generally, when one uses a radio to get information, you are using interference that is unattended, or 
at least undefined, so it is up to you to figure out what meaning you can attach to it.  

One of the more interesting uses of a radio that I ever made was to find a break in an underground power line.  We 
lost power to our garage, so I turned on a light dimmer in the house which generates static on AM.  Some of that 
static tends to follow electrical lines.  I took a small AM radio, held it close to the ground, and slowly walked 
from the house to the garage.  I moved the radio left and right some as well to be sure that the static I was 
hearing was coming from the underground power line.  I found a place where the amount of statid dropped very 
quickly.  When I dug down, I found the break in the power line on my first dig.  Maybe some of it was luck, and 
there are other, more reliable ways of tracing an underground power line, but it worked.

Best regards,

Steve Jacobson
