I need some help for a customer on wiring a helicopter headset plug into
the XCOM rado.

The plug in question is known as a Nexus plug or a US Nato plug or a
U-174/U or a TP-101, you can see how it becomes hard to find out what
this really is.....

Does anyone know what the different connectors are ??

Tip 1
Ring 2
Ring 3
Ring 4

Thanks in advance.... Michael Coates

I have an old Army SPH-4 (Viet Nam style helicopter type - well duh)
and use an adapter cable I got at flighthelmets.com (?).

If you find out what the rings connect to, let me know?
