I want to use the buttons on my grip to activate the push to  talk switch. Thinking that it should be a simple act of a momentary switch I cut  my factory switch wire into. Long enough to splice it back together if thing  went as they normally do. Instead of two wires, I find that there are four in  that little bundle. Any one know anything or at least enough to help me out  here? I have searched the internet and can't find anything other than where to  buy them.

OK, I just tested the four wires Red and Green are activated  when the button is pushed.  Black and white are also activated when the  button is pushed. My grip button has only two contacts. Anybody have a clue as  to how to wire this thing.[img]cid:003801c74316(at)usermj5tjr71vq[/img]

Hi Larry,

             When I was messin with my old com system...my PTT also had the 4 wires.... there were Two momentary switches...

One - normaly open

One- normaly closed



 What this did was cut-off andbody in the intercom , while the pilot is using the radio...



 Sounds like yours might be the same...



 You could , just use the two wires and elbow the passenger...He he he



  Or maybe you have something different...



 I think mine was Comtronics...



                             Gotta Fly...

This one is I-com. Here is a picture, perhaps that will help. If I weren't 

afraid of frying the final or something else in the radio, I would just 

connect the four wires together into two pairs and call it good.

Larry, Check the Aeroelectric List also here on Mattronics. Some one there will know exactly what to do with your particular set up.

Larry:



Don't take this for gospel, but I think the white wire is the PTT 

wire.  Ground it and the radio should go to xmit.



However, don't do that because I said so.  Let me see if I can find my 

schematic for my icom.

Does your PTT include a plug & jack for your headphone mic? If so, that 

would explain the extra wires.



Do you have an ohm meter? You can use it to identify which wires are 

tied together when the PTT is pushed & which wires go where at the plug 

end of the wire.



If you've got an ohm meter & need some help with how to identify the 

wires, let me know & I'll try to walk you through using it.

Re: Push to tallk switch.  I have never been able to get my ptt switch

to work with my JPH520 radio.  Recently, I was told that my radio may

not have the circuit for a ptt switch.  Guess that I should have bought

an Icom.

Well, it certrainly isn't definitive, but it truly focuses on who caused the problem. It certainly wasn't you, Larry. Bob is right, that info should have been forthcoming from the manufacturer. If we as consumers don't push back we will always be left to our own devices to fix what the manufacturer has left undone. It's one that should be proceeded with. You paid their asking price and they have let you down. If no one holds their feet to the fire they will never improve.
