Narco AT-150 Transponder
|Home > Manuals > Narco AT-150 Transponder > Product Description|
The AT 150 TSO 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 an optional altitude digitizer, Narco Model AR-500, is incorporated, coded altitude in- formation will be transmitted to the ground station.
The AT 150 has been designed for 14V operation, therefore a voltage converter, such as Narco Model MP-10, is required when the unit is installed in aircraft with 28 Vdc electrical systems.
The Narco Passive Voltage Converter Kit may be obtained, assembled, and used in place of an MP-10 or KP-15, however, this Converter can only support one (1) AT 150, whose Chassis Lever Code is KC or higher. See Optional Accessory list, Section 1.6 item g.
