RE: Airtronics question
All current Airtronics equipment used the "Z" connector. This connector is compatible with all other major radio equipment. The "Z" connectors are not the old connectors you are thinking about. Those old connectors had the power leads reversed from the rest of the industry and had to be modified to use with any other radio brand. But as I said, the current Airtronics equipment is compatible with all other major radio brands.
