Mike / Kolb friends –

 

I went thru the same exercise – trying to adapt a headset with a single jack plug to a handheld radio, which accepts TWO separate jack plugs.  Most standard general aviation headsets have two jack plugs – one for the phone, and one for the mic.  And most radios are designed to accept these two plugs.  However, there are some headsets (like maybe your Vietnam era helmet?) that combine both mic and phone functions into a single jack plug.

 

My Comtronics flight helmet is the same way: a single jack plug.  So when I wanted to connect this helmet directly with my handheld radio, I needed some kind of adapter cable.

 

I ended up purchasing a special patch cord from Comtronics, which combined a PTT switch (button) with a one-plug-to-two-plugs adapter built in.  

 

Cost was under fifty bucks.  I would recommend contacting the Comtronics … see if they can help with your setup.

 The Comtronics helmet (which I have, too) uses a single plug with three contacts.  The military helmets have a single connector with four contacts.  The female connector to match is a little harder to find, you won't find it at Radio Shack but it is available online.



 I ended up making my own adapter cable to work with my Icom A24 (dunno if it's the same wiring as the A14).  It's permanently installed in the plane, with the PTT inside the control stick tube.



 The military helmet microphone will probably not have the correct impedance to work with the newer Icom radio.

I will probably use my Comtronics helmet as well. 



I do believe the connector was called a U174 for the old helmet. 



Thanks!

All those connectors and adapters is what have kept me from using a radio.  I admit that, since I fly few hours out of

my own strip, there is no urgent need,  but what the hey!  -shouldn't I be able to plug my old headset into my icom?



What were these folks thinking?  As far as I'm concerned it's all a bunch of overpriced BS.  If it were mainstream

you could buy a complete setup, ready to go for $50 at dollar general.  -I have more important priorities.

 The old GA microphones used a telephone standard microphone and plug, and the standard stuck.  There's no room in a modern handheld radio for that great big plug, so Icom and others had to use modern small plugs... and they provide an adapter (at least they did with my A24).  Along comes Comtronics and others and it's a lot less cumbersome to use a single plug, so another adapter is needed (and of course the military helmet uses a different standard.  So it goes.

Check on Matronics Aero Electric Forum for a handheld to military headset/helmet adapter and PPT.
