Steve,  I wouldn't due to the cabin noise on a single, regardless of it being a rotary or conventional.  A second headset is much better and gives you a spare if necessary.  Neil.

Hi guys
I’m wiring my GTR225 radio in at present and wondering about the external speaker provision.
Does anyone put such a speaker into their cockpits?

Cheers
