[Elecraft] Remote on/off of the K3

[Don Wilhelm]

Gary,

The way to remotely turn the K3 ON is to pull the ACC connector pin 8 to 
ground (ACC pin 5 or 12). See Remote Power On in the manual.

There is a command to turn the K3 OFF in the K3 Programmer's Reference, 
but when powered off, the serial port is not powered, so it could not 
respond to any power on command.  Unlike computer motherboards, 
everything in the K3 is turned off (except the batery powered real time 
clock).
