K3 remote power on.

[Randy-3]

I am interested in a way to remotely power on a k3 or k3s without the remote rig boxes. Nice apps already exist to remotely operate the kat500 and kpa500. Any suggestions?

Why? Remote operation of my second k3 for digital modes.

Assistance appreciated.

Randy

I use an Arduino connected to the internet using the Arduino internet shield. The Arduino sets a relay on/off as desired, to turn my radio on/off. It also connects/ disconnects my antenna.

I do basically the same thing to control my KX3 when I'm on holiday. The
info I needed is on pages 5 and 28 of the KX3 manual: briefly assert 9V on
the PTT ring of the mic plug. From skimming the K3 manual, it looks like
the K3 is even easier: just (briefly, I assume) ground the PTT line on the
ACC port.

My shack radio is a Raspberry Pi. When I need remote power on, I breadboard
up a simple relay circuit that allows one of the Pi's GPIO pins to control
a 9 V battery. I use TRRS/TRS breakout adapters to pass through audio
unchanged, while connecting the PTT ring to the output of that relay. Then
a have a trivial Python program on the Pi that briefly asserts that GPIO
pin.
