K2 microphone adapter

Just put this together so that all the 'functions' are external, (mostly for testing)

I wired it up...

Foster 8 pin plug.

Pin 1 AF
Pin 2 PTT
Pin 3 Down
Pin 4 Up
Pin 5 FUNC
Pin 6 5V DC 
Pin 7 GND
Pin 8 GND

You cannot see it but I put a 3.5mm socket for a PC mike on the right hand side of the poting box. I MIGHT label the buttons as likely to forget but big one is PTT, red are down and up, black is func (not implemented in K2 anyway). The 5V is visible on a small pcb board in the box.
