Hi,

   I am normally on the Kolb list and one of the guys there suggested that I could find the answer to one of my problems here. I have a grip on my stick that has five buttons, one of which is supposed to be a push to talk button. However it only has two connections on it. The other buttons control my EIS. I had thought that a I-Com push to talk switch was merely a momentary switch. When I cut into the wire I find a red, green, white and black wire. The red and green show continuity when the button is pushed. The white and black also are a closed circuit. I really don't want to screw things up, can anybody enlighten me as to the best way to hook this up.

Thanks

   Correct. ALL PTT buttons are normally open, momentary

   operation.

   Then use these two wires.

   Didn't your stick grip come with a schematic? If not,

   contact the suppler and suggest that his product is

   NOT ready for prime-time until it's shipped with

   lucid, tell-all instructions.
