The KT-74 will be the next transponder on your "to-get" list.  With plug-and-play compatibility with the KT-76A/C and KT-78A model transponders, this is the easiest way to meet the 2020 ADS-B compliance date (when coupled to an appropriate GPS source).  Matched to the style of  new generation of Bendix/King avionics, the KT-74 offers an intuitive user interface.  Pilots can simply enter the assigned squawk code into the unit with the push of four buttons, while VFR and emergency squawk codes can be directly entered with the touch of one button.  Flight ID is also supported.
