[RFI] RFI Direction Finding

I bought a $30 Radio Shack VHF aircraft radio receiver for the purpose.  It 
is AM, not FM, and works very well.  I can track noise down to the exact 
pole.

But the problem I have is travelling along the road with it.  With every 
vehicle I have, ignition noise is as strong as the noise I am trying to 
sniff out.  The bicycle is usually not an option because the main  highway 
has a gravel shoulder.  I have been known to speed up in the car, turn off 
the ignition, and coast while trying to find the noise.  If I think it is 
nearby, I sometimes just walk with the radio to my ear.
