I do NOT have the problem (and I've had people listen carefully for it) with an 
Alpha 86 at full power located 4 feet from the K2.  For what it's worth the 
front panel of the Alpha is perpendicular to the front panel of the K2.  The 
Alpha has an enormous Hypersil transformer, as Earl mentions.

I did have the problem with my HAM/2 antenna rotor control box closer than about 
two feet from the K2.
