If it doesn’t work, you can build a two input audio amplifier for about $3. But you’d have to wire it in to 12v power.

Is is possible to utilize a Y cable to connect a headset to a hand-held and panel radio at the same time? The situation would be no intercom panel, Garmin GTR200, Yaesu FTA-550, and twin plugs on the panel for a headset. This topic link indicates OK http://forum.matronics.com/viewtopic.php?t=37809 but it refers to an intercom panel. However, the Audio Systems chapter seems to indicate that either radio would not sense an resistance in the other so the headset would not receive much useful output. My thought is the handheld could function as a back up to the GTR200 and or second frequency monitor if the volume was turned up with out the need to change the headset plugs from one to the other.

You can try it . . . there's no risk
of damage . . . it simply would not
work as you expect.
Adding multiple audio sources together
is normally done with an audio
isolation amplifier as described
in the chapter. As to microphones,
the mic in your headset can be connected
to only ONE transmitter at a time.
You would need a XMTR1/XMTR2 microphone
transfer switch.
So if you're only needing the HT for
backup, you might as well transfer the
headphones audio with the same switch.
