Overview

 

Compact, lightweight and affordable, the BendixKing KTR 909B UHF Communication Transceiver offers the flexibility to meet your specific communications needs. Providing superior two-way AM voice communications, this unit was specifically designed for international governmental, military and paramilitary applications, and have already been specified for use in U.S. Air Force and U.S. Navy training programs.This all-solid-state unit accesses frequencies from 225.000 to 399.975 MHz in 25 kHz increments, and is specifically designed for low maintenance and high reliability. The KTR 909B offers full-time guard frequency (243.000 MHz) monitoring via a dedicated second receiver, while the KTR 909 scans other frequencies when the unit is not in use.

The KTR 909B incorporates an ARINC 429 bus interface that can allow control from an FMS, Radio Management Unit (RMU), or Integrated Avionics System. The KFS 599B can be used as the primary controller, or as a back-up controller. The KFS 599B features 20 user programmable channels and standard easy-to-read, gas-discharge displays or a Night Vision Goggle (NVG) compatible display.

Manual Frequency Selection
The Manual Frequency display mode is selected by momentarily depressing the Channel Mode select button. In this mode, the upper line of the frequency display is blank while the lower line displays the operating frequency. The frequency may be changed by rotating the concentric selector knobs, thus allowing direct entry of the desired frequency.

Preset Channel Selection
The Preset Channel display mode is selected by momentarily depressing the Channel Mode select button. In this mode, the upper line of the frequency display indicates the preset channel number. Twenty user- programmable channels are available for quick access to commonly used frequencies. The guard channel is also available for transmission and reception in this mode. Preset channels may be changed by rotating either of the concentric selector knobs.

ADF Mode
The KTR 909B can provide tuning for remote ADF systems. The ADF mode is selected by pressing the Receiver Mode Select button. The UHF transmitter is then disabled and the signal received by the KTR 909B is directed to the external ADF processor.  When the ADF Mode is enabled and active, the MN annunciator is illuminated and the letters ADF appear in either the frequency display (when preset/guard mode is active) or the channel display (when manual frequency mode is active). During ADF operation, the guard receiver is not active.

Remote Channel Mode Select
A remote-mounted switch may be installed to toggle both the KFS 599B between Manual Frequency display and Preset Channel display modes.

Remote Channel Increment
A remote-mounted switch may be installed to place the KFS 599B in the Preset Channel display mode and incrementally scan through the channels. Operating this switch will advance the preset channel number by one count.

Receiver Mode Selection
The KTR 909B receiver can monitor either the main or guard frequencies, or can monitor both simultaneously. The receiver mode is selected by momentarily depressing the Receiver Mode select button. Receiver modes are annunciated in the display’s upper right hand corner and indicator, providing full ADF capability throughout the associated UHF band

Transmitter “Push Tone”
When the transmitter is keyed and the inner Frequency Selector knob is depressed, the transmitter will transmit a 1000 Hz tone.

Stuck-Mic Protection
When a microphone is keyed for more than 90 seconds, the control unit reverts to receive mode and the display flashes, alerting the pilot to a stuck-microphone condition. This prevents the radio from jamming the selected frequency.

Configuration Options
This installation option for the KTR 909B permits an FMS to control the system, with the KFS 599B used as a backup controller. Ideal for training purposes, this tandem installation permits either the KTR 909B or KTR 909 system to be managed via two control heads.
FMS Control Head Option Tandem Control Head Option Flight Management System ControlWith its ARINC 429 interface, the KTR 909B may be controlled through an FMS. The KFS 599B may be installed as a backup controller for an FMS, but simultaneous FMS and KFS 599B operations are not supported.

Tandem Control Head Operation
Dual control units can be installed for tandem operation of either the KTR 909 or KTR 909B, where one unit is designated the master and one is the slave.In tandem operations, only those pre s e t channels stored in the master control unit are available to the slave unit. A Control – Disable feature allows the installation of tandem KFS 599A/B units so that data entries may be made from either controller.

Support
As with all of our products, the KTR 909 and 909B are backed by our comprehensive 2-year “no-hassle” warranty and supported by a comprehensive worldwide dealer network.
