UHF TRANSCEIVER GENERAL INFORMATION This pilot’s guide contains information about and instructions for operating the KTR 909/909A UHF Comm Transceiver with the KFS 599A UHF Comm Control Head. The KTR 909 must be installed and operated with a KFS 599A UHF Comm Control Head. The KTR 909A can be operated with either a KFS 599A UHF Comm Control Head or a Radio Management System (RMS) using the ARINC 429 interface. This pilot’s guide only covers operation using the KFS 599A UHF Comm Control Head.
On/Off/Vol/Test Knob The On/Off/Vol/Test Knob turns the KFS 599A UHF Comm Control Head on, off, and adjusts volume when rotated. Pressing this knob alternately removes and applies squelch. On units without volume control, the audio level is controlled by the aircraft audio/radio control system. U VOL OFF PUSH TEST Channel Select Button The Channel Select button switches the unit between the manual and preset frequency selection modes and also enables the programming CHAN mode.
The frequency range of the radio is 225.000 MHz through 399.975 MHz in 25 kHz increments. When the farthest right digit is 2 or 7, the selected frequency is XXX.X25 MHz and XXX.X75 MHz respectively. When the farthest right digit is 0 or 5, the selected frequency is XXX.X00 MHz and XXX.X50 MHz respectively (e.g., when 399.97 is displayed, the selected frequency is 399.975 MHz).
Annunciators Three annunciators are displayed on the right side of the top display line. These annunciators are: • Transmit (TX) • Main (MN) • Guard (GD) Transmit Annunciator The Transmit Annunciator (TX) is illuminated when the microphone is keyed or the 1kHz Tone knob is pressed.
Selecting the Receiver Mode One of three receiver modes may be selected using the Receive Mode Select (MODE) key. The modes are Main, Both, and ADF. Main Both ADF Transmitting and Receiving on the displayed channel is enabled when the MN annunciator is illuminated. Scanning of both the Guard and Main receiver frequencies. When the receiver detects a signal on either frequency, scanning stops on the active channel. The annunciator associated with that frequency is displayed.
Selecting a Preset or Guard Frequency The CHAN button is used to switch the radio between manual and preset channel selection. To select a preset frequency: • Momentarily press the CHAN button to select the Preset/Guard Frequency Mode (top display line shows either “CH” followed by a number or “Gd”). • Rotate either Frequency/Channel Select Knob to cycle through the available channels. Only programmed channels will be displayed.
Semi-Duplex Programming This is available if the semi-duplex option was enabled during installation. Different transmit and receive frequencies (semi-duplex) may be programmed into every channel except the Guard. If semi-duplex operation is desired, then perform the following steps: • Press and hold the CHAN button for at least three seconds. The top display line will flash P01 indicating the programming mode is active on channel 1.
Programmed Channel Deprogramming To deprogram a channel, perform the following steps: • Press and hold the CHAN button for at least three seconds. The top display line will flash P01 indicating the programming mode is active on channel 1. • Rotate either the small or the large Frequency/Channel Select Knob to change the channel number. • Momentarily press the MODE button, the frequency display begins to flash.
Remote Channel Request This switch, when momentarily pressed, will perform one of two functions. If the KFS 599A is in the manual frequency mode, it will change to the preset channel mode. If the KFS 599A is already in the preset channel mode, it will change the channel to the next higher programmed channel. Program Disable This line will disable and enable the programming function of the KFS 599A.
