Third order mixing products, Marty.

(2 * frequency of local #1)  plus or minus  (frequency of local #2); 
you sometimes hear only one of these locals, but it's the combination 
of the two that causes it.  The mixing occurs either in your radio, 
or at some external point, possibly where there is corroded metal 
that is acting like a diode.


In the 540 case (2*610) - 680 =  540

660:    (2*610) - 560 = 660


Is KEAR (I think; still KFRC in what passes for my mind) close to you?


best wishes,

Nick
