EXTRA 300S
916.1 GENERAL
The BENDIX/KING KT 76A panel mounted transponder receives interrogations at 1030 MHz,
and these trigger a coded response of radar pulses, which are transmitted back to ATC at 1090
MHz. The return reinforces your aircraft’s image or „blip“ on the controller’s radar screen.
The KT 76A can reply to radar in any of 4096 preselected codes. Each code is identified by a
unique group of pulses. With either an separate encoder, the KT 76A also provides ground radar
with a continuos report of your altitude, which are automatically updated in 100-foot increments.
NOTE
The KT 76A owner accepts all responsibility for obtaining the proper license before using
the transponder.
916.1.1 CODE SELECTION
The Identification Code selection is done with 4 ATCRBS Code Selector Knobs that provide 4,096
active identification codes. Each of the 4 Code Selector Knobs selects a separate digit of the
identification code. There is no need to move the „caret“ back to the first digit; it will automatically
return after about five seconds. The KT 76A will retain the reply code through power shutdowns
if the code has not been changed during the 5 seconds prior to removing power.
IMPORTANT CODES:
1200 The VFR code for any altitude in the US (Refer to ICAO standards elsewhere)
7000 The VFR code commonly used in Europe (Refer to ICAO standards)
0021 The VFR code commonly used in Germany (default is set to 0021 at time of
installation)
7500 Hijack code (Aircraft is subject to unlawful interference)
