canadair chanencjer OPERATING MANUAL KP 601A-6 SECTION 6 COMMUNICATIONS 1. GENERAL The a i r c r a f t communication systems consist of the following systems: VHP communication system HF communication system Selcal system Audio integrating system Flight compartment voice recorder system 2. VHP COMMUNICATION SYSTEM (Figures 1 and 2) The VHF communication system provides short-range AM voice communication over the frequency range of 118.000 to 151.975 MHz. The system i s a dual system, consisting of the VHF communication system No. 1 (VHF 1) and the VHF communication system No. 2 (VHF 2 ) . Control and selection of the VHF 1 and VHF 2 audio are provided by the audio integrating system. The VHF 1 and VHF 2 consist of a transceiver, a control unit and an antenna each. 3. HF COMMUNICATION SYSTEM (Figures 3 through 5) The HF communication system is used for long-range voice communication over the high-frequency band (2.000 to 29.999 MHz) and operates in the upper sideband (USB), lower sideband (LSB), amplitude modulation equivalent (AME), continuous wave (CW), or optional frequency modulation (FM) mode. Communication is possible in simplex or half-duplex mode, and the system is monitored by the selective calling (Selcal) system (refer t o paragraph 4 . ) . The system consists of two HF radio f a c i l i t i e s (HF1 and HF2) operating through a common notch antenna. The HF communication system consists of two HF receiver-exciter units, two power amplifier-coupler units, two control units and a single notch antenna. SECTION 6 Page 1 Apr 02/87 chauenaer OPERATING MANUAL PSP 601A-6 SELCAL SYSTEM (Figures 6 and 7) The selcal decoder permits ground stations equipped with tone-transmitting HF communication equipment to call the aircraft by means of a coded signal. When the correct coded signal is received, the aircraft decoder produces an output to the aural warning system to operate the selcal chime tone- The selcal system also provides outputs for two PRESS TO RESET switch/lights on the selcal control unit- The PRESS TO RESET switch/lights indicate incoming calls for the associated HF communication system. Selective calling eliminates the necessity of continuous monitoring of HF frequencies by the flight crew. A TEST switch on the selcal control unit permits the selcal system to be tested. The selcal system consists of the decoder unit and associated annunciators and the switch/lights. AUDIO INTEGRATING SYSTEM (Figures 8, 9 and 10) The audio integrating and interphone are combined into one system. The audio integrating controls are described in the systems which the controls concern. The audio integrating system receives audio inputs from the following systems: VHF navigation systems (VHF/NAV 1 and VHF/NAV 2) Automatic direction finder systems (ADF 1 and ADF 2) Distance measuring equipment systems (DME 1 and DME 2) Aural warning system VHF communication systems (VHF 1 and VHF 2) HF communication systems (HF 1 and HF 2) The interphone provides communication between the pilot, copilot and three ground crew stations- Interphone communication can be made, without the use of any controls, between any two stations in the systems, with one exception: if a pilot's MIC selector switch is in position 1 or 2, the pilot can listen on interphone but cannot talk on i t . When the switch is in the INPH position, the microphone output is routed to the interphone line. The INPH position of the MIC selector switch is a hot mike position for interphone operation. SECTION 6 Page 2 Apr 02/87 OPERATING MANUAL PSP 601A-6 The interphone channels do not have volume controls. The microphone circuits for the nose wheel well and the API! stations are disconnected in flight. An emergency mode of operation is automatically initiated by the system when a power supply failure occurs in the pilot's or copilot's audio channel in the audio electronics unit. In this mode, the pilot's or copilot's microphones and keylines bypass the audio electronics unit and are connected directly to the associated VHF radio sets. Also, audio from the associated VHF and NAV receivers, and from the aural warning and voice advisory systems is connected directly to the pilot's and copilot's headphones. 6. FLIGHT COMPARTMENT VOICE RECORDER SYSTEM (Figure 11) The flight compartment voice recorder system continuously records radio communication, flight crew conversations, and flight compartment sounds. The audio integrating system (refer to paragraph 5.) supplies the communications input signals to the flight compartment voice recorder system. The input signals consist of all signals transmitted and received over the pilot's microphone headset. Flight crew conversations and flight compartment sounds are picked up by the microphone monitor and remote microphone. Operation of the compartment voice recorder is automatic and begins when the aircraft busses are energized. SECTION 6 Page 3 Apr 02/87 OPERATING MANUAL PSP 601A-6 RMT ANNUNCIATOR indicates when the VHP communication system is remotely tuned. Not used in this installation. S\ ACTIVE ANNUNCIATOR Rashes while the active frequency is changed. Continues to flash if the actual frequency differs from that shown on the display ACTIVE FREQUENCY DISPLAY Displays the active frequency, diagnostic messages, and memory channel numbers. PRESET FREQUENCY DISPLAY Displays the preset (inactive) frequency, diagnostic messages, and memory channel frequencies. MEM ANNUNCIATOR Indicates when a stored frequency is displayed in the lower display. VOLUME CONTROL Controls the receiver audio level. MODE SELECTOR ON and OFF positions switch system power. SQ OFF position disables the receiver squelch. AUTOMATIC DISPLAY DIMMER SENSOR Automatically controls the display brightness. SELF-TEST PUSHBUTTON Inmates the transceiver self "test TRANSFER/MEMORY RECALL SWITCH in the XFR position, the displayed preset frequency becomes the active frequency and the transceiver retunes. in the MEM position, one of the six memory frequencies is loaded into the preset display. Six operations of the switch cycle all memory frequencies through the display. TRANSMIT ANNUNCIATOR Indicates that the transceiver is transmitting. FREQUENCY SELECTORS Selects the active or preset frequency. The outer knob changes two digits to the left of the decimal point in 1-MHz steps. The inner knob changes the two digits to the right of the decimal point in 5t>kH2 steps, or in 2S-kHz steps after the direction of rotation is reversed. ACTIVE PUSHBUTTON Enables the frequency select controls to directly retune the transceiver active frequency. Deletes the preset frequency display while direct tuning ts m progress.
