cdavis Posted November 13, 2006 Share Posted November 13, 2006 I have a Sigtronics intercom with King radio. It would be nice to be able to plug a cell phone in so I could make a quick call in flight (Honey, I'll be there in about 20 minutes) while monitoring the radio. You cannot hear anything on a cell phone over cabin noise. I'm thinking of plumbing in a cell phone headset wire into a passenger input of the intercom. Is this as simple as it seems? Just install a small plug and wire it into a passenger intercom interface? Or is there something I'm missing (impedence matching, etc).

Marc Zeitlin Posted November 13, 2006 Share Posted November 13, 2006 Is this as simple as it seems?Nope. Or is there something I'm missing (impedence matching, etc).Yup. Totally different impedances. There are at least two or three companies selling cell interfaces for headsets/intercoms - they go for anywhere from $100 - $200. Look for their ads in the magazines or on line. Don't expect to get a signal above 3K ft AGL, and there only if you're lucky. Quote Marc J.

cdavis Posted November 14, 2006 Author Share Posted November 14, 2006 Marc, Thanks for the reply. It hardly seems worth the effort. However, it does give me an idea for a new bumper sticker, "Hang Up and Fly" Quote Link to comment Share on other sites More sharing options...
