PRODUCT DESCRIPTION
The AT165 TSO (KT76 Replacement herein referred to as the AT165) is a panel mounted unit designed to be a
slide in replacement for existing KT76 installations. The AT165 provides all the features of KT76 with
additional enhancements.
The AT165 TSO is a panel-mounted transponder with additional altitude and timing functions. The AT165
consists of a receiver tuned to the frequency of a ground interrogation station (1030 MHz), logic circuitry to
check the validity of the received interrogation and encode a reply containing pertinent identification
information, and a transmitter which sends the coded reply to the ground station. When connected to an
optional Altitude Digitizer (AR850) coded altitude information will be transmitted to the ground station.
The AT165 utilizes a single knob for error free code entry even in turbulence. Push button controls are used to
access and manipulate the added features. The front panel display has two distinct areas, one for the primary
transponder functions and the second for the altitude and timing functions.
The AT165 has been designed for 14V or 28V operation. If the AT165 is replacing a KT76 that uses a passive
voltage converter this does not have to be removed.

1.7.1
FUNCTION SELECTOR SWITCH
The function selector is a four position rotary switch. The four positions are:
OFF- Turns off all power to the transponder.
SBY- Turns the transponder power supply on. When in SBY, the transponder will not reply to any
interrogation. SBY is used at the request of the air traffic controller to selectivity clear his scope of
traffic. When in this mode SBY will be shown on the Code display window.
ON- Places the transponder in Mode A, the aircraft identification mode. In addition to the aircraft's
identification code, the transponder will also reply to altitude interrogations (Mode C) with discrete
signals that do not contain altitude information. When in this mode ON will be shown on the Code
display window.
ALT- The ALT position activates all the necessary circuitry (transponder to optional altitude digitizer and
return) to respond to ATC (Air Traffic Control) altitude interrogations and aircraft identification
interrogations with standard pressure altitude (29.92 inches Hg). The ALT position may be used in
aircraft that are not equipped with the optional altitude digitizer, however, the only response will be
discrete signals that do not contain altitude information. When in this mode ALT will be shown on the
Code display window.

INTRODUCTION
SECTION 1
1.7.2
CODE SELECTOR/DATA ENTRY SWITCH
Pressing the Code Selector/Data Entry Switch once enables Transponder Code entry. The left most code digit
will begin flashing. Turning the switch selects the code and pushing the switch again moves to the next digit
from left to right. Once code selection has started, all four digits must be set before the code entry is completed.
A total of 5 pushes completes the code entry process. If the switch is inadvertently pressed, it will stop the code
entry process automatically in 10 seconds. The VFR code can subsequently be recalled automatically by
pressing the VFR button. Code entry can not be started if the AT165 is in setup, Count Down Timer set, or
Altitude Buffer set modes.
1.7.3
IDENT
Pressing the IDENT button will activate the SPIP (Special Position Identification Pulse) signal for
approximately 20 seconds. This signal will "paint" an instantly identifiable image on the controller’s scope.
This signal must only be used upon request of a "Squawk IDENT" from the controller. Use at any other time
could interfere with another aircraft sending a SPIP. The IDENT legend will appear in the Code window while
the Ident signal is being sent.
1.7.4 VFR
Pressing the VFR button will cause the squawk code to either change from the user entered code to a VFR code
or change back to the user entered code from the currently displayed VFR code. The last used squawk code is
automatically recalled when the unit is cycled off and on.
1.7.5 HOLD
Pressing the HOLD button will enter the Altitude Hold mode and lock the current altitude as the HOLD
altitude. The Altitude display area will now show the altitude difference relative to the HOLD altitude in 100ft
increments. The altitude display area will flash if the Altitude Buffer value is exceeded. This is a warning only
and is not tied to any navigation systems.
Depressing the HOLD button for two seconds or longer will allow the setting of the Altitude Buffer. The
available range is 200ft to 2500ft. Once set, momentarily pressing HOLD again will save this buffer value. The
buffer value will be retained when the unit is powered off. This mode must be exited before other functions can
be accessed. Once started this mode will be exited when it has been inactive for 10 seconds.
HOLD again will save this buffer value. The buffer value will be saved when the unit is powered off.

1.7.6 FUNC
Pressing the FUNC button cycles the timer display between Flight Timer, Count Up Timer, and Count Down
Timer.
Holding the FUNC button in for 5 seconds or longer will Flip/Flop the left and right display areas. This
function is extremely useful in the unlikely event of an unreadable LCD display. When the unit is turned off it
will always restart with the displays in their default locations.
1.7.7 START/STOP
Pressing the START/STOP button will independently start or stop the Count Up and Count Down timers
depending on which is currently displayed.
1.7.8 CRSR/CLR
When in Flight Timer, depressing the CRSR/CLR button for two seconds will reset the Flight Timer.
When in Count Up Timer, depressing the CRSR/CLR button for two seconds will reset the Count Up Timer.
When in Count Down Timer, with the timer stopped, momentarily pressing the CRSR/CLR button once will
recall the preset count down time. Momentarily pressing this button again will activate the cursor in the timer
window. At this point, changes to the Count Down Timer value can be made by using the Code Selector/Data
Entry knob.

2.5.2 SETUP
Starting with the AT165 turned off, hold in the FUNC button while turning the function switch to the SBY
position. The AT165 will now be at the contrast adjust screen. Rotating the data entry switch CW or CCW will
adjust the display’s contrast. Once the desired contrast is achieved pressing the FUNC button will save this
setting and continue to the Display mode screen (V1.02 software) or VFR set screen (V1.03 and later software).
The VFR set screen allows the setting of the code displayed when the VFR button is pressed. Rotating the data
entry switch will change the digit value and pressing the data entry switch will change the flashing cursor to the
next digit. Pressing the FUNC button will save the new VFR value and continue to the Display mode screen.
The Display mode screen allows three choices for the display: AUTO, POS, and NEG
AUTO – Black letters on a light background switching to light letters on a black background as the
ambient light is reduced.
POS- Black letters on a light background.
NEG – Light letters on a black background.
Pressing the FUNC button will save the Display mode setting and continue to the GRAY code input page.
The GRAY code input page shows the current altitude and the status of each of the GRAY code altitude inputs.
A filled box indicates a ground on the altitude input. This screen is used as an aid in installation
troubleshooting. Pressing the FUNC button exits the setup procedure.
2.5.3
Flight Test
After installation, a flight test should be performed to check overall operation and system compatibility.
A. Range Test
1. The AT165 should furnish a strong and stable return signal to an interrogating radar facility that is 50 NM
away when the aircraft is flying at 6000 feet. At this altitude and distance, fly a flat circle while having a
FAA station monitor the transponder return signal. There should be no more than two sweeps of the
interrogating radar without a return response.
B. Surveillance Approach
1. Perform an approach to a runway of an airport starting at least 10 NM from the airport served by Airport
Surveillance Radar (ASR) having an Air Traffic Control Radar Beacon System (ATCRBS) facility.
Alternately, a simulated approach and letdown may be made along a path parallel to, but separated, three
to four miles from a vertical plane through the location of the ASR facility. The approach should be made
at the normal rate of decent and normal approach and landing configuration for the aircraft and should
continue down to an altitude of 200 feet. Not more than one "drop out" should occur for any 10 radar
sweeps during final approach.
C. Electromagnetic Compatibility
1. The transponder should not cause the performance of other systems aboard the aircraft to be degraded
below their normal capability and transponder operation should not be adversely affected by other
equipment.
