Look for an 18-wheeler with a 200-amp Leece-Neville alternator where the 
headlights dim when the signal comes on.  Probably a bunch of old 6JE6 
sweep tube boxes in the truck bed.  You may also hear a loud inverter 
whine.  :-)

Seriously, how are you getting the 120 dB attenuation?  You can probably 
use a crystal diode and a 50-microamp meter with a shunt pot when you 
get close.
