Partly correct. Pressing the power button to turn off initiates a shutdown
procedure. Pin 8 is only grounded momentarily when you power on and does
not stay grounded while powered up. Powering down by simply removing power
is not recommended.

Actually it's pin 8, not 5. I use the DTR line on a COM port, with a
transistor level converter (identical to the simple FSK RTTY
interface[1]), to trigger it, with custom software. For testing
purposes, Hercules[2] is quite handy.

You need to provide a way to ground pin 5 on the aux connector. I do this
with a remoterig interface. Any remote relay will work. This turns on the
rig then the rig stays on even if the closure is momentary. To turn it off
you need to send it the power down command via the command serial port. A

You can turn the K3 off with a software command. To turn it on, you need to
manipulate the level of one of the AUX I/O pins (the 15-pin connector on the
back of the rig). That could be done by an external device of some sort.
