Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 The KT 73 has an Air/Ground discrete which, when connected to a strut switch on the aircraft, can disable ATCRBS and Mode S All-Call replies when the aircraft is on the ground. A front panel switch position, ’GND’, can also be used by the pilot instead of the strut switch.

Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 1.3.2 KT 73 RECEIVER CHARACTERISTICS Sensitivity Variation with Frequency: The RF input level required to produce 90% replies will not vary by more than 1 dB and will at no time exceed a level of -69 dBm for standard ATCRBS interrogations in the frequency range be- tween 1029.8 and 1030.2 MHz.
Page 13
Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 RF Peak Power Output: The transmitter output power will be 125 watts (21.0 dBW) peak power minimum and 500 watts (27.0 dBW) peak power maximum at the terminals of the transponder antenna. The pulse ampli- tude variation between any two pulses in an ATCRBS reply will not exceed 1 dB.

The instructions for continued airworthiness given in the TC or STC approvals for this product sup- plements or supersedes the instructions for continued airworthiness in this manual. Most Honeywell products are designed and manufactured to allow "on condition maintenance." On condition maintenance is described as follows; There are no periodic service requirements necessary to maintain continued airworthiness.

Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 The KT 73 must be kept a minimum of three feet from the antenna. Additionally, the antenna coax cable should not be bundled with the other wiring harnesses to the KT The length and routing of the external cables must be carefully planned before at- tempting the actual installation.

Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 2.3.4 EQUIPMENT LOCATION Care should be exercised to avoid mounting components near equipment operating with high pulse current or high power outputs such as radar and satellite communications equipment. In general, the equipment should be installed in a location convenient for operation, inspection, and maintenance, and in an area consistent with the TSO environmental limits.
Page 24
Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 2.3.5 KT 73 INSTALLATION The mounting tray for the transponder should be mounted using the dimensions specified in the outline and mounting drawing, Figure 2-4. The mounting tray should be wired according to the system interconnect diagram, Figure 2-5 through 2-10.
Page 25
Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 In retrofit installations where a Configuration Module does not exist, the KT 73 will recognize this condition and operate from the data contained in the internal memory. In this arrangement, the configuration data will be lost when the KT 73 is replaced with a different unit, such as a loaner, and must be re-entered.

Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 Once the terminal is in the correct position, close the jaws gently until the terminal is held loosely in place. Push the wire stop down so that it rests snugly behind the contact portion of the terminal. Strip off 1/8 inch of the wire insulation and insert the wire through the insulation tabs into the conductor tabs until the insu- lation hits the conductor jaw face or until the conductor touches the wire stop.
