As others have suggested, use the null of a rotatable loop. But also 
consider the possibility that the mix is happening in one of the 
transmitters involved in the mix. That does sometimes happen. To pursue 
that, contact the engineer for the stations involved.

Mixes like this can be very difficult to track down. In Chicago, I had 
intermittent low level 160 mixes from clear channel stations 20 miles 
away that I never did find.
