[Elecraft] KAT-100

[Don Wilhelm]

Tom,

Would it not be easier to simply connect the KAT100 permanently to the 
secondary power supply?

If you have the secondary supply always connected to the K2 (and powered 
on) for backup QRP operation, then I don't understand why you would want 
to provide a switch in the KAT100 power line.  There is no real 
advantage to powering the KAT100 from the same supply that powers the 
KPA100.  You would have to be certain the secondary supply is powered on 
first, but that should be easy enough to accomplish.

Or perhaps you are envisioning some other operating situation that has 
not occurred to me yet.
