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.
N O T E
The KT 76A owner accepts all responsibility for obtaining the proper license before using
the transponder.
