2. Description and Operation
A. Transponders, General
The transponder is a receiver/transmitter which operates at radar frequencies. It transmits
transponder code and altitude data to the Air Traffic Control Radar Beacon System (ATCRBS).
The transponder replies to interrogation signals from the ATCRBS mode A secondary surveillance
radar (SSR) at 1030 MHz. The reply signal at 1090 MHz gives the code which can be set on the
cockpit display. A REPLY indication comes on when the equipment is transmitting.
The transponder can also give altitude data in reply to mode C interrogation. The transponder
transmits data from the blind encoding altimeter to the ATCRBS.
The transponder has an ident button (IDENT or IDT). Push the ident button to transmit a special
identification pulse. The ident pulse identifies the airplane to the air traffic controller.

B. Bendix/King KT 76A Transponder
Figure 1 shows the Bendix/King KT 76A transponder. It is located in the instrument panel at the
bottom, see Chapter 31.
The avionics bus or, if installed, the essential avionics bus supplies power to the transponder. The
ALT/BAT switch and the AVIONICS MASTER switch must be set to ON to supply power through
the XPDR circuit-breaker to the transponder. Refer to Chapter 92 for the wiring diagrams.
Turn the function selector switch clockwise from the OFF position to set the transponder on. There
is a 45 second delay after setting the unit ON from OFF to let the transmitter tube warm-up. The
function selector switch has these positions:
) SBY Sets the transponder to the standby position. The transponder receives signals but does
not transmit.
) ON If the transponder receives a mode A interrogation, it transmits the mode A code set by
