Just purchased from another pilot to install in my plane. We installed and attempted to have it certified today but it is putting out 1083 MHz. It will need to be tweaked by an avionics shop to get it within tolerance of 1090 Mhz. Transponder looks brand new. Comes with a new tray and connector. No screws for the connector. $250 plus shipping.
