I've done some work at the Barter Theatre, and they have a very odd setup for a wireless com. Somehow they use motorola walkies, and have them connected to the clear-com system. When a walkie transmits, it is heard on all wired coms. In order to talk to the walkies though, you must hold both the call light and mic buttons. Has anyone seen this anywhere else, or can anyone explain to me how this works and/or how you would go about setting this up? Needless to say that someone has gotten very inventive for sure.
