TRANSPONDER

Looking a pedestal section of a B767-300 cockpit is possible identify several type of Transponder depending from choice of a Company. Of course in my (our) case, I've choose the Transponder used on 767LevelD that at difference from other, contain a keypad rather than knobs for set the squak code.

The panel include all the functions simulated in LevelD software; the keypad (9 key) is easily connected by a IDC 10pin (flat cable) to Mastercard.

At now need two knobs to finish the panel....
