Providing superior two-way AM voice communications, these units were 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.The 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 909 scans other frequencies when the unit is not in use.The KFS 599A control head is used as an interface for the KTR 909. The control head features 20 user programmable channels an easy-to-read gas-discharge display or 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.
Remote Channel Mode Select
A remote-mounted switch may be installed to toggle both the KFS 599A between Manual Frequency display and Preset Channel display modes.
Remote Channel Increment
A remote-mounted switch may be installed to place the KFS 599A in the Preset Channel display mode and incrementally scan through the channels. Operating this switch will advance the preset channel number by one count.
Transmitter “Push Tone”
When the transmitter is keyed and the inner Frequency Selector knob is depressed, the transmitter will transmit a 1000 Hz tone.
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.
Designed for training purposes, dual KFS 599A control units can operate in tandem mode allowing either controller to communicate with the KTR 909 system.
Tandem Control Head Operation
Dual control units can be installed for tandem operation of the KTR 909, where one unit is designated the master and one is the slave.
In tandem operations, only those preset channels stored in the master control unit are available to the slave unit. A Control – Disable feature allows the installation of tandem KFS 599A unit so that data entries may be made from either controller.
As with all of our products, the KTR 909 is backed by our comprehensive 2-year “no-hassle” warranty and supported by a comprehensive worldwide dealer network.
