[Elecraft] K2 power

[Brent Sutphin WB4X]

I have a K2 with the KPA100 installed and have just finished the KAT100. I 
power the rig with an Astron SS30.  I have been thinking about where to get 
power for the KAT100.  What I am thinking about doing is to remove and/or 
jumper D10 in the K2. This would put 12V on the K2's J3 (12V DC Jack) on the 
back of the K2.  I could use J3 as an auxiliary power source, with just a 
short cable from the K2 to the KAT100.  Any comments about this idea?  Good 
Idea or Not?
