Proven Performance And Leadership
The KT 76A has established a worldwide reputation as the standard in Mode A/Mode C identification. Since its introduction, more than 165,000 KT 76 and KT 76A transponders have been installed worldwide.
The KT 76A is a Class 1A transponder providing maximum performance at altitudes up to 35,000 feet. This compact unit was among the first of our avionics to incorporate Large Scale Integrated (LSI) circuitry, reducing both weight and power requirements. And today, its design efficiency and rugged construction offer a near-ideal balance of performance, reliability and value.
A Closer Look
All Mode A and Mode C transponders perform the same functions: replying to radar interrogations, providing Air Traffic Control (ATC) with positive identification, and showing your ground speed on the controller’s radar monitor. With an encoding altimeter or blind encoder, the transponder can also transmit altitude.
The KT 76A combines an extra-rigid, durable switchboard with easy access to all components. Unlike other transponders the 76A can be opened like a book to expose every part and printed circuit board—significantly reducing maintenance costs and downtime. Inside the KT 76A, “solder masked” printed circuit boards provide trouble-free connections and ensure that all leads are fully insulated, protecting against overheating of components during manufacturing.
While other transponder manufacturers solder their LSI chips in place, the KT 76A’s encoder and decoder functions are programmed into a plug-in LSI chip, making repair as simple as pulling out one chip and replacing it with a new one.
While the IDENT button is readily accessible on the front of the faceplate, a remote button can also be installed in an even more convenient location, such as the control yoke, to reduce pilot workload during busy approaches or departures. It is this attention to detail that makes the KT 76A one of the most successful transponders in general aviation history.
