[Elecraft] Remote on/off of the K3

[Rick WA6NHC]

Here is the answer that I sent him:

My entire K line is managed by a computer.  I use a USB board with a 
pair of relays (only need one) and some specific software (shortcut on 
the desktop) to tickle the ACC line to turn the K3 on when I am remote 
operating.

is one example.

The software is at:

And naturally since I put this together, I've not had a power failure.

73,
Rick
