Don,

Thanks for the info - sounds easy. I did buy the KAT100-2, planning on doing 
this after hearing all the discussion on the reflector. This will make a nice 
pair in the shack, and provide the portability/mobility I want. Hey, I may even 
try mobile operation for the first time ever with the QRP rig. 

73,
