display on the right will cycle through
all the detected faults. If the faults are
associated with external data, an
audio message “CHECK FAULT
CODES” will be annunciated. Faults
internal to the KT 73 will annunciate
an audio message “TRANSPONDER
TEST FAIL”. Internal faults will also
cause “FAIL” to be annunciated in the
lower left of the display in any mode
of operation.
The fault codes are as follows:
F1YY* - Squitter (Internal)
F2YY* - Internal or External
EEPROM
(Internal)
F3YY* - Hardware (Internal)
F401 - Mode S address/Max
Airspeed
(Internal)
F5YY* - Gilham or Executive

F6YY* - Interface (External)
*
YY
denotes
the
specific
fault.
Except for the acquisition data
fault (code 101), the KT 73 will not
inhibit replies when an internal fault is
identified.
GND (GROUND) - The KT 73 will
inhibit ATCRBS (Air Traffic Control
Radar Beacon System),
ATCRBS/Mode S All Call and Mode
S-only All Call replies. However, the
unit will continue to generate Mode S
squitter transmissions and reply to
discretely addressed Mode S
interrogations. The ID code is shown
on the right side of the display and the
letters "GND" are shown on the left
side.
NOTE: An optional remote
"air/ground" switch may be installed.
This feature eliminates the need to
manually place the KT 73 in the GND
mode. In addition, when the aircraft is
airborne, the KT 73 will function as
though the Function Selector Knob is
in the ALT position when it is actually
in the GND position.
ON - The KT 73 is able to reply to all
valid Mode A, C and S interrogations.
However, the altitude information will
not be transmitted. In the ON mode,
the altitude window is left blank and
the ID code is shown on the right side
of the display.
ALT (ALTITUDE) - The KT 73 replies
to all valid Mode A, C and S
interrogations. The ID code is
displayed in the right window and
altitude information (in hundreds of
feet) is shown on the left. The letters
"FL" will be illuminated, indicating
Flight Level. If altitude information is
unavailable or invalid, the left portion
of the display will be dashed.
DISPLAY BRIGHTNESS
ADJUSTMENT - The KT 73's display
brightness is controlled by an ambient
light sensor. In addition, it has a
manual adjustment to allow for
matching to the brightnes of other
