[Kenwood] Possible replacement for SM-220?

[rbethman]

Greg,

He's out the expense of an SM-220 already.  He doesn't want to throw 
that much more again to resolve the problem.  The spectrum analyzer 
route isn't where he wants to go right now.

I simply wanted too warn him about computer methods.  I had to get out a 
HP-312A to track down each "critter" that was throwing "junk" throughout 
the shack.
