Yaesu – SCU-42 – Headset Adapter Cable with PTT connection

Headset adapter for your Yaesu FTA-250, FTA-450, FTA-550L, FTA-550AA, FTA-750L, or FTA-850 series aviation transceiver.

Allows you to use any standard general aviation headset with dual plugs (PJ-055 and PJ-068) with your Yaesu transceiver.

The Yaesu SCU-42 headset adapter now has a dedicated PTT connector to seamlessly incorporate a separate external PTT switch.

This is a direct replacement of the Yaesu part SCU-15 that is now discontinued.  The SCU-15 was the same thing but without the PTT connector.
