Voice Operated Switch (Relay). Generally used for voice keying of transmitters or intercoms/interphones but because it basically a sound activated switch it can be used to control anything a switch or relay does. ie: "The Clapper"

The VOX is voice activated. Learn how to adjust it so you can cut out the wind noise activation. The higher the setting then one needs to talk louder too. No need for a PTT switch.

 

PTT Needed for bike to bike communication.

 

I was wrong about this.

I was going to put a PTT button in line with a set of M/F DIN's for my headset but I when I checked out the PTT pin on the tank DIN It appears to be disconnected. I am not reading any pull-up voltage on it nor do I measure any resistance against ground or any of the other pins.

Sorry bout that
