All airplane equipment I am listing is untested and is being sold AS/IS with no guarantee that they will work properly. Please look carefully at pictures to determine condition for yourself because I do not know anything about these electronics. I also do not know much about how to price them, so I am going to list all of them a little high to see what offers come in. Any questions or offers are welcome, I will provide more close up pictures if needed be. The dials do appear to function correctly
