Frequency of operation ranges between 2.0 and 29.9999 MHz with 100 Hz resolution. Systems with a KCU 951 Control Unit may set the upper frequency limit to 22.9999 MHz or 26.9999 MHz. NOTE: Operations are limited to 25 MHz for aircraft installation by aeronautical mobile band frequency limits. A configuration is called a “dual system” when two KHF 950 HF/SSB systems are installed in the same aircraft to share one antenna. Both systems may receive simultaneously, but only one system is chosen to transmit at any one time. Either a manual or an auto select transmit scheme determines which system is selected to transmit. In a manual select system, a switch in the cockpit is used to determine if “System 1” or “System 2” will be used for transmitting. In an auto select configuration, the first system (System 1 or System 2) to be keyed is selected to transmit, and transmission from the other system is inhibited until the first system has stopped transmitting. Interconnect drawings for both manual and automatic selection are provided in this manual. Revision 2 23-20-03 Page 6 Apr/2006 N KHF 950 HF/SSB SYSTEM INSTALLATION MANUAL In a dual system when one system is transmitting, receive on the other is disabled. The single antenna in a dual system can be tuned to only one frequency at any given time. If the two systems are tuned to different frequencies the strongest reception is realized on the primary system, which is tuned to the same frequency as the antenna. The primary system is defined as the selected system in manual configuration, or the system that was last used for transmission in auto-select configuration. A dual system requires certain accessory equipment: KA 158 Bridging Amplifiers and KA 160 Dual Antenna Adapter or KA 162 Dual External Capacitor (if required). The function of the KA 160 Dual Antenna Adapter and KA 162 Dual External Capacitor is to connect the antenna to the active antenna coupler. The function of the two KA 158 Bridging Amplifiers are to divide and route the received signal from the active antenna coupler to both KTR 953 Receiver/Exciters. NOTE: A dual installation using a KA 98 probe antenna, shunt, notch, or short grounded wire antenna requires the use of the KA 162 Dual External Capacitor instead of a KA 160 Dual Antenna Adapter. When two independent HF systems employing two separate antennas are used on one aircraft, it is important to maximize separation between the antennas. A minimum of 6 ft. (2 m.) separation is recommended, and the antennas should be configured as orthogonally as possible. The KCU 951 Control Unit or KFS 594 Miniature Control Unit with KA 594 Bus Adapter determines the frequency and mode of operation of the system, and displays that information to the pilot. A remote mounted KA 594 Bus Adapter is required for systems that employ a KFS 594 Miniature Control Unit. Receiver and low level transmitter signals are located in the KTR 953 Receiver/Exciter. Originally the KTR 953 Receiver/Exciter employed an oven controlled oscillator, which required a short warm-up period to generate the frequency reference required for the synthesizer. The oven controlled oscillator has been replaced by a temperature compensated crystal oscillator (TCXO), which provides an “instant on” frequency reference in current production models of the KTR 953 Receiver/Exciter. The KAC 952 Power Amplifier/Antenna Coupler amplifies the excitation signal from the KTR 953 Receiver/Exciter to 150 watts PEP, or 37 watts of carrier power in AM. The amplified signal is routed into the antenna coupler section of the KAC 952 Power Amplifier/Antenna Coupler which matches the various impedances of the antenna to the 50 ohms output of the transmitter. In receive function, signals from the antenna pass through the antenna coupler to the KTR 953 Receiver/Exciter. Revision 2 23-20-03 Page 7 Apr/2006 N KHF 950 HF/SSB SYSTEM INSTALLATION MANUAL Accessory items include an 8.3 ft. (2.54 m.) KA 98 Antenna for applications where larger antennas are not practical. A KA 161 External Capacitor unit or KA 162 Dual External Capacitor unit is used to allow the antenna to more efficiently tune short grounded antennas. In a dual installation when two KHF 950 HF/SSB systems share one antenna, two KA 158 Bridging Amplifiers along with a KA 160 Dual Antenna Adapter or KA 162 Dual External Capacitor unit are required.

It operates in a frequency range between 2. Both systems are allowed to receive simultaneously. SelCal. and Secure Voice communication. the KHF 950 HF/SSB system capabilities can be increased to allow the system to support Data. NOTE: Some systems require special versions of system components and special wiring considerations to be part of the original installation and are not intended as an upgrade. System capabilities can be matched to user requirements through choice of system components.A System Functional Overview The Bendix/King KHF 950 HF/SSB Communication System supports a wide variety of communication requirements.A.9999 MHz offering several different emission modes to provide voice communication.(1) System Power UP When power is first applied to the system (by rotating OFF/ON VOL Control clockwise). the active channel or frequency is displayed (systems which employ the older KTR 953 Receiver/Exciter with a crystal oven have a blank frequency display during the 2-4 minute warm up period). By including the appropriate components in an installation.N KHF 950 HF/SSB SYSTEM INSTALLATION MANUAL 4. 4. An Auto Select or Manual Select scheme is employed to select which system is transmitting. The active channel or frequency is the last channel or frequency used for transmit prior to system being turned off. System Function 4. transmit is inhibited and the frequency digits flash to indicate the fault. the AM and USB messages are both illuminated. Active frequency reappears upon completion of the coupler tune sequence. 4. The coupler monitors SWR during transmit. The frequency selected. except for systems employing limited frequency options. If a PA or coupler fault is detected. When operating in the optional A3A mode on the KCU 951 Control Unit. the direct frequency mode is accessed when the FREQ CHAN button is in the out position. Revision 2 23-20-03 Page 65 Apr/2006 . The coupler generates a READY signal that inhibits the auto tune sequence until a channel change occurs. Frequency selection is accomplished by means of cursor/digit increment/decrement switch with only simplex operation allowed.6:1 at the end of a transmission. Should the SWR degrade to a ratio greater than 3. The frequency display is blanked again during the auto tune cycle. Using a KCU 951 Control Unit. Depressing the microphone key or a channel change clears the fault indication.A.A. the coupler starts a tune cycle synchronized with the next microphone key depression. Depressing the Mic key initiates the auto tune sequence. Emission mode and channel number continue to be displayed. emission mode selected and TX message are displayed when the KHF 950 HF/SSB system is transmitting. Transmit is allowed on any 100 Hz frequency increment between 2 to 30 MHz frequency range. When transmitting in the channel mode.(2) Channel Operation Channel number. No channel number is displayed when operating in the direct frequency mode. 4.(3) Direct Frequency Mode Operation in the direct frequency mode is similar to the channel mode except that the frequency is selected as directly rather than on a preprogrammed basis. The coupler is switched to the bypass condition when a channel change occurs. the transmit frequency and an added TX message are displayed.N KHF 950 HF/SSB SYSTEM INSTALLATION MANUAL Depressing the microphone key button momentarily initiates the coupler’s auto tune sequence. Rotation of the inner control knob causes the channel to be incremented or decremented. emission mode and active frequency are displayed. and the TX message flashes. Revision 2 23-20-03 Page 66 Apr/2006 . For example. a pilot operated switch performs this function. This type of tuning is called rollover and is enabled in the aircraft wiring harness. The cursor control is the outer concentric knob for the KCU 951 Control Unit and the inner concentric knob for the KFS 594 Miniature Control Unit. Both work in an increment/decrement fashion. The antenna coupler’s transmitter output is disengaged (bypassed) while changing between channel and direct frequency modes of operation. In a dual system both KHF 950 HF/SSB systems are allowed to receive simultaneously. Depressing the microphone key causes the cursor to go to the hidden position. In a system with Manual Select. When changing from channel mode of operation to direct frequency mode of operation the control unit restores frequency and mode selections last used for transmit purposes while operating in the direct frequency mode.B Dual System An installation with two KHF 950 HF/SSB systems that share a common antenna is a dual system. The cursor hidden position is a blank space between the least significant digit and the most significant digit. but only one system is allowed to transmit at a time.N KHF 950 HF/SSB SYSTEM INSTALLATION MANUAL The direct frequency mode is accessed with the KFS 594 Miniature Control Unit by selecting Channel 0". the digits revert to 80. The KCU 951 Control Unit has the capability of a borrow/carry type of tuning. and two frequency digits are 89 with the cursor on the 9. If rollover is not enabled. Auto Select systems employing KCU 951 Control Units use interlock relays to select the transmitting system. Without rollover. An Auto Select or Manual Select scheme is employed to select the transmitting system. Cursor position is annunciated by flashing the active digit. A new auto tune sequence is initiated with the microphone key. This allows ease in continuous tuning up and down the frequencies (in 100 Hz steps). The cursor occupies one of six positions and moves left to right for clockwise knob rotation for the KCU 951 Control Unit or by pressing the cursor knob for the KFS 594 Miniature Control Unit. the user may select each frequency digit individually without borrowing from or caring to the next digit. if rollover is enabled. It is also bypassed if the selected frequency is changed. One more clockwise rotation of knob changes the digits to 90. 4.
