GENERAL
The
Bendix/King
Transponder (Type KT 76C), shown
in
Figurel
1, is
the
airborne component
of an Air Traffic Control Radar
Beacon
System
(ATCRBS). The
transponder enables
the ATC
ground
controller
to
"see"
and
identify more readily
the
aircraft

the
radarscope.
The
blind
encoder
(SSD120-20)
enables
the
transponder to automatically report aircraft altitude to
ATC.
The
Bendix/King Transponder system consists
of a
panel-
mounted
unit and an
externally-mounted
antenna. The
transponder
receives interrogating pulse signals
on
1030 MHz and
transmits
coded pulse-train reply signals
on
1090
MHz.
lt
is
capable
of
replying
to
Mode
A
(aircraft identification) and also
to
Mode
C
(altitude reporting) interrogations on
a
selective reply basis
on
any
of 4096
information
code selections.
A
sidewall-mounted SSD120-
20
Blind
Encoder
is
included
in the
avionic configuration,
the
transponder
can provide altitude reporting
in
1OO-foot
increments
between -1000 and +20,000 feet.
The KT 76C features
microprocessor
and LSI (Large
Scale
lntegrated)
control.

using
the rotary knob and numeric buttons and all functions including
the
flight level altitude are presented on
a
gas discharge
display.
