Don't rule out the possibility that it could be a noise-maker in a home 
or office near you. Examples include battery chargers (for power tools, 
mobility scooters, etc.), power supplies for consumer equipment, and 
plasma TV sets.  If that's true, you could tune a portable AM broadcast 
radio to a dead spot near the top of the AM band and walk around with 
it to chase it down. 

Your radio will have a loopstick antenna. Remember also that they have 
a deep null off their ends and a very broad broadside peak, so you may 
be able to use the null to triangulate the source. The null may, 
however, be shifted by wires around you.
