GENERAL INFORMATION
1.1 INTRODUCTION
This manual contains information relative to the physical, mechanical, and electrical characteristics of the Bendix/ King KY 96A and KY 97A VHF Communication Trans­ceivers. Installation and operating procedures are also included. Information relative to the maintenance, alignment, and procurement of replacement parts may be found in the KY 96A, KY 97A Maintenance/ Overhaul Manual.
1.2 DESCRIPTION OF EQUIPMENT
The KY 96A and KY 97A VHF Comm Transceivers consist electrically of five sections: receiver, transmitter, synthesizer, display circuitry, and the microprocessor board. The transceivers are identical except that the KY 96A operates at 28 Vdc and the KY 97A operates at 14 Vdc.
The KY 96A, KY 97A is currently available with 25 kHz receiver selectivity, 100 mW into 500 ohms or 8 W into 4 ohms audio outputs (4 W into 4 ohms in the KY 97A), and operating ranges of 118.000 to 136.975 MHz. See paragraph 1.4 below for descrip­tions of specific versions.
NOTE: Previous versions were available with 50 kHz receiver selectivity; however,
it is not a current configuration.
The KY 96A, KY 97A has the capability of programming up to nine memory channel frequencies for later recall. Channel frequency information is stored in non-volatile memory so that when the radio is turned off and then back on, channel information is retained. Both units also have the capability of remote transfer of Use and Standby frequencies, and remote recall of channel frequency information.

*1 Will work but backlighting will be too bright and unsuitable, and the audio amplifier will not function because the current installation is not wired for an audio amplifier.
NOTE: Use good quality stranded wire with at least 600 V insulation that will not
support a flame.
2.3.1 Avionics Cooling Requirements for Panel Mounted Equipment
The most important contribution to improved reliability of avionics equipment is to limit the maximum operating temperature of each unit. While modern designs consume less total energy, the heat dissipated per unit volume (watts/cubic inch) remains much the same due to contemporary high density packaging techniques. While each indi­vidual unit may or may not require forced air cooling, the combined heat generated by several units operating in a typical panel or rack can significantly degrade the reliability of the equipment if provisions for adequate cooling are not incorporated in the initial installation.
2.3.2 Mounting Rack Installation
2.3.2.A. The KY 96A, KY 97A is mounted rigidly in the aircraft panel. Select a position
in the panel that is not too close to any high external heat source. Remember to allow adequate space for installation of cables and connectors. Avoid sharp bends and placing the cables too near the aircraft control cables.
2.3.2.B. When installing two or more panel mounted units in a stack, the mounting
trays shall be spaced 0.050 inches (0.127 cm) apart. Current production mounting trays have 0.025 inch (0.064 cm) dimples built in to top and bottom and both sides so that the trays will automatically be spaced properly.
2.3.2.C. Refer to Figure 2-5 for the KY 96A, KY 97A mounting dimensions. Mark and
cut the mounting holes.
2.3.2.D. Secure the mounting rack to the instrument panel per Figure 2-5 and Figure
2-6. The rear mounting bosses should be attached to the airframe by means
of support brackets.
2.3.3 Antenna Installation
A conventional 50 ohm vertically polarized comm antenna is required with the KY 96A, KY 97A. Vertical bent whip antennas are not recommended. Wideband comm anten-
Rev 4, Apr 2003 IM 006-00674-0004.dwd Page 2-2
Page 17
B KY 96A, KY 97A
nas provide efficient operation over the comm band. Antennas should be installed per manufacturer’s recommendations. Additional recommendations are as follows:
2.3.3.A. Mount antenna on a flat metal surface or install a ground plane at least 18
inches square.
2.3.3.B. The antenna should be well removed from any projections and the engine(s)
and propeller(s). Also, for satisfactory operation, the antenna isolation be­tween a communications transmitter antenna and a nav receiver antenna, as well as between dual comm antennas, should be a minimum of 30 dB. VHF antennas mounted on top and bottom have approximately 30 dB isolation. A horizontally polarized nav antenna and a vertically polarized comm antenna will have practical values from 10 to 30 dB.
2.3.3.C. If both comm antennas must be top mounted or both bottom mounted, anten-
na isolation between comms may not be adequate to prevent re-radiation. In single audio panel installations, re-radiation can be prevented by use of the XMT-REC interlock. Refer to Installation Bulletin #194. In dual audio panel installations where simultaneous operation of both comms is desired, the XMT-REC interlock is not recommended.
2.3.4 Cable Harness and Connector Assembly
The KY 96A, KY 97A uses a special connector that mates directly with the printed cir­cuit board inside the unit. Assembly of the connector is as follows:
2.3.4.A. Contact Terminal Assembly using Molex Crimper (see Figure 2-4)
2.3.4.A.1 Strip each wire 5/32 inch for contact terminal, P/N 030-01107-00XX. (The last
two digits of the part number indicates the number of terminals required).
2.3.4.A.2 Open the Molex HT 1921 hand crimper with the engraved side toward the op-
erator. Place the conductor tab section of a contact terminal on Anvil A with the contact portion facing away from the operator. Close the crimper slightly until the contact tabs touch the female jaw.
2.3.4.A.3 Insert the stripped conductor until the insulation is even with the side of the
crimper facing the operator. Crimp the conductor tabs by squeezing the han­dles together until the jaws are fully closed or a sufficient crimp is obtained.
2.3.4.A.4 Move the lead to Anvil A. Place the insulating tab section on Anvil A. Crimp
again until the jaws are fully closed or until a sufficient crimp is obtained.
2.3.4.B. Contact Insertion into Molex Connector Housing
After the contact terminals have been installed on the wiring harness, the contact ter­minals can be inserted into the proper location in the connector housing (P/N 030­01094-0080). The terminal cannot be inserted upside down. Be sure to push the ter­minal all the way in until a click can be felt or heard. The self-locking feature can be tested by gently pulling on the wire.
2.3.4.C. Location of Polarizing Key in Housing
Rev 4, Apr 2003 IM 006-00674-0004.dwd Page 2-3
Page 18
B KY 96A, KY 97A
Prior to insertion of connector into rear of unit, check polarizing key position between contacts 8 and 9. Refer to Figure 2-6 to check correct position of polarizing key.
2.3.4.D. Extraction of Contact from Molex Connector
2.3.4.D.1 Slip the flat narrow blade of a Molex HT-1884 contact ejector tool, P/N 047-
05099-0001, under the contact on the mating side of the connector. By turn­ing the connector upside down one can see the blade slide into the stop.
2.3.4.D.2 When the ejector is slid into place, the retaining tab of the contact is raised,
allowing the contact to be removed by pulling moderately on the lead.
2.3.4.D.3 Neither the contact or position is damaged by removing a contact; however,
the contact should be visually checked before reinstalling to be certain that re­taining tab “A” extends as shown in Figure 2-4 for retention in connector.
2.3.4.E. Coax Connector
Refer to Figure 2-7 for instructions for mounting the right angle coaxial BNC connector to the coax cable. Install the connector into the mounting rack.
2.3.5 KY 96A, KY 97A Installation
2.3.5.A. Looking at the top of the unit, make sure the front lobe of the hold down device
is in a vertical position.
2.3.5.B. Slide the unit into the mounting rack until the front lobe touches the mounting
rack.
2.3.5.C. Insert a 3/32 inch Allen wrench through the hole in the front panel to engage
the locking screw. Turn clockwise until the rear lobe engages the mounting rack. Continue turning until the unit is secure in the mounting rack. DO NOT OVERTIGHTEN.
2.3.5.D. To remove the unit turn the locking screw counterclockwise, using a 3/32 inch
Allen wrench, until the unit disengages from the mounting rack. Pull the unit out of the mounting rack by pulling on the metal tabs located behind the front panel on each side of the unit.
2.4 POST INSTALLATION CHECKS
An operational performance flight test is recommended after the installation is com­pleted to insure satisfactory performance of the equipment in its normal environment. Check all aircraft control movements to be sure no electrical cables interfere with their operation. To check the communications transceiver, maintain an appropriate altitude and contact a ground station facility at a range of at least 50 nautical miles. Then con­tact a ground station close in. Pull the volume control out to defeat the automatic squelch feature and listen for any unusual electrical noise which would reduce the comm receiver sensitivity by increasing the squelch threshold. If possible, verify the communications capability on both the high and low end of the VHF comm band.

B KY 96A, KY 97A
CAUTION: BEFORE FLIGHT, CHECK THE ANTENNA VSWR. THIS SHOULD BE
CHECKED WITH AN IN-LINE TYPE WATTMETER INSERTED IN THE COAXIAL TRANSMISSION LINE BETWEEN THE TRANSCEIVER AND THE ANTENNA. ANY PROBLEM WITH THE ANTENNA INSTAL­LATION WILL MOST LIKELY BE SEEN AS A HIGH REFLECTED POW­ER. VSWR OF 3:1 WILL RESULT IN A 25% LOSS OF POWER.
NOTE: The LCD back lighting can be set for the most pleasing intensity by ad-
justing the panel lighting. See paragraph 3.6 of this manual for dim se­lect.
2.4.1 Adjustments
The KY 96A, KY 97A are factory adjusted to accommodate typical requirements for most aircraft configurations. However, baseline mic gain, sidetone, carrier/noise squelch, and carrier squelch may be adjusted through the cover for specific aircraft configurations. See Figure 2-1.

SECTION III
OPERATION
3.1 POWER ON UNIT
To power on the unit, rotate the Volume (VOL) knob clockwise from the OFF position. When power is activated the Use and Standby (STBY) windows will display the fre­quencies and/or mode stored in the non-volatile memory before power down. After ac­tivating power, pull the VOL knob out to override the automatic squelch and rotate the VOL knob to the desired audio level. Push the VOL knob back in to activate the auto­matic squelch.
CAUTION
: THE KY 96A, KY 97A SHOULD BE POWERED ON ONLY AFTER EN-
GINE STARTUP. THIS IS A SIMPLE PRECAUTION WHICH HELPS PROTECT THE SOLID STATE CIRCUITRY AND EXTENDS THE OP­ERATING LIFE OF YOUR AVIONICS EQUIPMENT.
3.2 TRANSMIT INDICATOR
During Comm transmissions, a TX will appear between the USE and STBY windows to indicate that the transceiver is in the Transmit mode of operation.
3.3 MODES OF OPERATION
3.3.A. Frequency Mode
Frequency selection is accomplished in the Standby Entry mode by changing the fre­quency display in the STBY window of the display with the tuning knobs, and then transferring the selected frequency into the USE window by pressing the Transfer but­ton. The larger tuning knob will increment or decrement the MHz portion of the display in 1 MHz steps with rollover at each band edge (118.000 MHz or 135.975 MHz). The smaller tuning knob will increment or decrement the kHz portion of the display in 50 kHz steps with the knob pushed in or in 25 kHz steps with the knob pulled out. While in the Standby Entry mode, the transceiver remains tuned to the frequency displayed in the USE window at all times.
NOTE: Extended Frequency units will rollover at 118.000 and 136.975 MHz.
3.3.B. Channel Mode
Momentarily pressing the Channel (CHAN) button while in the Frequency mode puts the radio in the Channel mode. The last active frequency remains tuned and displayed in the USE window. The last used channel number is displayed in the channel digit unless no channels have been programmed, in which case the radio defaults to Chan­nel 1 and dashes are displayed in the STBY window. Turning either tuning knob changes the channel number and corresponding frequency in the STBY window. The channels will only increment and decrement to channels that have been programmed. If there has been no activity for five seconds the radio will return to Frequency mode and the channel frequency is placed in the STBY window. Pressing the CHAN button

before the five second delay is completed will return the radio to the Frequency mode and the status of the Frequency mode prior to entering Channel mode remains the same.
When in Channel mode, pressing the Transfer button will return the radio to Frequency mode. The channel frequency will become the new USE frequency and the last USE frequency will become the new STBY frequency. If the radio was in Direct Tune mode (see paragraph 3.3.E below) prior to entering Channel mode, pressing the Transfer button or allowing the radio to time out will bring it back to Standby Entry.
3.3.C. Program Mode
The Program mode is entered by pressing and holding the CHAN button for longer than two seconds. The last active frequency remains tuned and displayed in the USE window. The last used channel is displayed when Program mode is entered. The channel number flashes and turning either tuning knob changes the channel number. Pressing the Transfer button will cause the frequency associated with that channel to flash. The tuning knobs then work as in the Frequency mode, except that between the rollover points (118.XX and 135.XX or 136.XX) dashes are displayed. These dashes are used to de-program channels, and to display a channel that is unprogrammed. When the channel frequency is flashing, pressing the Transfer button will cause the frequency to stop flashing and the channel number to start flashing at which time a new channel may be selected for programming.
3.3.D. Program Secure Mode
Program Secure mode is used to secure or lock the frequency that is assigned to a channel so that the frequency assigned to that channel cannot be changed. All chan­nels or individual channels can be Program Secured. The following list of operations is given to Program Secure or Un-Program Secure a channel:
To Program Secure a Channel * Hold the CHAN button in for more than 2 seconds (Program mode). * Momentarily press the Transfer button (flashing frequency). * Change channel frequency to desired Program Secured frequency. * Ground the Program Secure pin (TP 701). * Momentarily press the Transfer button (Flashing channel number). * Unground the Program Secure pin.
To Un-Program Secure a Channel * Hold the CHAN button in for more than 2 seconds (Program mode). * Ground the Program Secure pin (TP 701). * Momentarily press the Transfer button (flashing frequency). * Unground the Program Secure pin. * Momentarily press the Transfer button (Flashing channel number).
3.3.E. Direct Tune Mode
Rev 4, Apr 2003 IM 006-00674-0004.dwd Page 3-2

B KY 96A, KY 97A
The Direct Tune mode is entered from the Standby Frequency Entry mode or Channel mode by pushing the Transfer button for longer than 2 seconds. The tuning knobs op­erate as in Standby Frequency Entry, but will change the USE frequency, rather than the STBY frequency. The radio will be tuned to the Active frequency.
Momentarily pushing the Transfer button returns the radio to Standby Frequency En­try. The Standby frequency prior to Active Entry mode remains unchanged.
3.4 REMOTE FREQUENCY TRANSFER (J96A pin 11 or J97A pin 12)
The Remote Frequency Transfer button operates identically to the front panel Transfer button with the exception that holding the Remote Transfer button for two seconds does not place the radio in the Active Entry mode.
3.5 REMOTE CHANNEL INCREMENT (J96A, J97A pin L)
Pressing the Remote Channel button will cause the system to enter the Channel mode of operation and will increment the channel from the previous channel number used.
3.6 DIM SELECT (J96A, J97A pin A)
When Dim Select is in the open position, display backlight dimming will track a 14 V lighting bus. When Dim Select is connected to ground the display backlight brightness tracks or follows a 28 V lighting bus. When Dim Select is connected to the aircraft sup­ply voltage the display backlighting will be at half brightness.
