[Elecraft] K2 Remote DC Power Control

[KG3VTomZ at gmail.com]

I am assembling a remotely-operated K2 station. I need a timer that will  
kill a "runaway transmitter." I am planning to install a kill-switch on the  
12 volt DC supply, as that is the only way I can be sure to disable the  
transmitter. If I have a K2 and the separate 100W power amp, is it  
sufficient/safe to just disable the power to the K2 base unit (leaving  
power to the amp connected)?

Anybody else experienced in auto-shutoff of a K2?

Thanks,

Tom, KG3V
