[Elecraft] K3: As remote Base

[Fred Jensen]

It's the I/O RJ45 connector on the back of the 1258, pin 4, that will 
key the remote radio, I use it with a Winkey3.  Pin 8 it ground, and 
while it is documented in a combination of schematic and pin-out 
diagram, it is, as Rick says, decidedly non-obvious.
