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.
