We got this intercom for use in the Cub. It works well but the Aerocom III that we had has a better auto-vox functionality when you have the door open, so we had the Aerocom repaired and now this unit needs a new home. It's in like-new condition except for having white velcro (the loop side) affixed to the back. The PTT switch is included. This is the version that plugs directly into an ICOM A6 or A24 radio (and some other models). We paid $150 plus shipping. It's yours for $100 shipped to the lower 48.
