Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 SECTION I GENERAL INFORMATION 1.1 INTRODUCTION This manual contains information relative to the physical, mechanical, and electrical characteristics of the Honeywell KT 73 Mode S Transponder. Installation and operating procedures are also included. Information relative to the maintenance, alignment, and procurement of the replacement parts may be found in the KT 73 Maintenance/Overhaul Manual, P/N 006-15563-0000. 1.2 1.2.
Impress Tryout 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. 1.2.3 Features The KT 73 is capable of interfacing to the Traffic Information Service (TIS).
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 1.3 TECHNICAL CHARACTERISTICS 1.3.
Impress Tryout 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 between 1029.8 and 1030.2 MHz.
Impress Tryout 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 amplitude variation between any two pulses in an ATCRBS reply will not exceed 1 dB. A Mode S reply will not contain a pulse amplitude variation, between any two pulses, of greater than 2 dB.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 1.4 1.4.1 UNITS AND ACCESSORIES SUPPLIED CONFIGURATIONS AVAILABLE P/N 066-01164-0101 is the only version of the KT 73 that is currently available. Included with the KT 73 is the mounting rack and the configuration module. The configuration module is optional but is strongly suggested. With the module, the installation unique configuration is maintained if a different KT 73 is swapped into the aircraft. 1.4.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 1.5 ACCESSORIES REQUIRED, BUT NOT SUPPLIED The following parts are recommended for a cable setup with dimensions of 4.5 feet to 11 feet: (See Figure 2-12, Sheet 1 of 2).

Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 1.6 LICENSING REQUIREMENTS For US registered aircraft, the transmitter, as installed in the aircraft, requires an Aircraft Radio Station License. This license is obtained by filing the FCC Form 404. While awaiting the receipt of the station license, a copy of FCC Form 404 must be kept in the aircraft.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 SECTION II INSTALLATION 2.1 GENERAL INFORMATION This section contains suggestions and factors to consider before installing the KT 73 Mode S Transponder. Close adherence to these suggestions will assure a more satisfactory performance from the equipment. The conditions and tests required for TSO approval of this article are minimum performance standards.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 NOTE: The TSO identifies the minimum performance standards, tests, and other conditions applicable for issuance of design and production approval of the article. The TSO applicant is responsible for documenting all limitations and conditions suitable for installation of the article.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 (2) 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 73. (3) The length and routing of the external cables must be carefully planned before attempting the actual installation. Avoid sharp bends or locating the cable near aircraft control cables.

Impress Tryout 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.
Impress Tryout 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. 2.3.5.
Impress Tryout 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.
Impress Tryout Preliminary - Subject To Change Without Notice BENDIX/KING KT 73 2.3.6.3 Contact Insertion into Molex Connector Housing (1) 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 03001094-0066). The terminal cannot be inserted upside down. Be sure to push the terminal all the way in, until a click can be heard or felt.
