[Elecraft] K2 Remote DC Power Control

Don,

Thanks for the reply, and for all your other help in configuring my K2  
station over the last 5 years.

Just out of curiosity - can this not be done if they are mounted in the  
same box? I think when mine were configured that way, there still were two  
separate 12V inputs - or do they get tied together? I would like to know if  
my timeout-switch approach would be useable by someone with the KPA-100 in  
the same chassis as the K2-base.

Interesting that it sound like it is not as "safe" to pull power from the  
K3 during operation. What about a natural power outage event? Would there  
be some complications in the recovery process?

73, Tom
