The manuals DV 14300.03 (“Installation and Operation”) and DV 14300.04 (“Maintenance and Repair”) contain the following sections. Section 1.2 DV 14300.03 DV 14300.04 General Information Installation Operation Theory of operation N/A Maintenance and Repair N/A Illustrated Parts List N/A Modification and Changes N/A Circuit Diagrams N/A Purpose of equipment The VHF transceiver enables voice communication in the very high frequency band between 118.000 MHz to 136.990 MHz (radio communication part of airband) with a channel spacing of 25 kHz in 25 kHz mode and with 8.333 kHz channel spacing in 25+8.33 kHz mixed mode. 1.3 General description The VHF transceiver is designed without any verified environmental class restrictions. It can be fitted in the instrument panel of all aircraft types. The VHF transceiver can be fully remote controlled via a RS422 interface and the industry established Commercial Serial Data Bus protocol. DV 14300.03/04 Issue 1 05/10 Page 1-1 AR6201 Configuration of the system is possible by means of a dedicated service interface implemented as a RS422 interface line with a proprietary serial data communication protocol. The VHF transceiver is a compact and lightweight single block unit. The dimensions correspond to the standard instrument diameter of 58 mm (2 1/4 inch). Mounting is by means of four screws (rear panel mounting). All controls and indicators are located on the front panel. The equipment connectors and the antenna socket are located at the rear of the unit. After switch on, the unit performs a self test (PBIT). After the PBIT the transceiver shows “WAIT” and the corresponding software versions of the control head and chassis module. If the PBIT detects a fatal error, the transceiver terminates operation and will be locked. The transmitter is designed for the 118.000 MHz to 137.000 MHz frequency range. The sidetone is available on the headphone output during transmission. The sidetone level can be set in the service menu. The frequency indication is by means of a liquid crystal display (LCD). The required operating frequency is set with the frequency selector switch. The pushbutton selects the digits. Memory channels The VHF transceiver also contains a memory device for storing 99 different frequencies which remain stored even with the unit switched off without an auxiliary battery. Last 9 frequencies are stored automatically. Mike inputs The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and an input for standard microphone (STD_MIKE). Each input is able to operate with single microphone or with 2 microphones of the same type connected in parallel. AF auxiliary input The AF auxiliary input enables AF signal switching of auxiliary units in the aircraft. The switched AF signals can be monitored in the reception mode only . Audio outputs The Headphone rated output power is ³ 300 mW @ 150 Ohm. The transceiver includes a speaker output (SPK). The rated output power from the Speaker Output is min. 4 W @ 4 Ohm The transceiver has an asymmetrical LINE output (LINE_OUT). When the transceiver is operating in RX mode the line output supplies the sum of intercom audio, receiver audio and auxiliary audio. When the transceiver is operating in TX mode, then the LINE output supplies the natural sidetone. Intercom mode Aircraft internal communication is possible in the intercom mode (IC). The intercom mode is activated by a long press of the SQL/IC button. Squelch Operation There are two kinds of squelch methods implemented. The carrier squelch (C_Squelch) and noise squelch (N_Squelch). The carrier squelch is based on received signal strength; the noise squelch is based on noise level detected in demodulated received signal. Page 1-2 DV 14300.03/04 Issue 1 05/10 AR6201 Scan sub mode The scan sub-mode is activated by a long press of the EXCHANGE/SCAN key in all selection modes. Illumination The VHF transceiver include a dimming input that controls illumination of LCD and push buttons. The dimming entry is either 14V AC/DC or 28V DC. The illumination can be dimmed from off to full illumination.The display has minimum illumination to ensure that the indicators are always visible. The characteristic of the dimming and illumination curve can be adapted to other units in the instrument panel in the service mode. The unit setup enables selection value of display contrast in range of 0 … 100 %. Monitoring stage for the power supply voltage The VHF transceiver also contains a monitoring stage for the power supply voltage which is activated when the VHF transceiver is switched on. If the supply voltage drops below 10.5 V (Low Battery Threshold), the display indicates the message “LOW BATT”. Emergency operation In emergency operation the following performance reduction is possible i.e. when the supply voltage dropped down to 9 V. p For TX Mode: RF Rated power is ³ 2 W @ 50 Ohm, modulation depth is ³ 50 %, p For RX Mode: (S+N)/N ³ 6 dB for RF level -93 dBm, m = 30% 1 kHz sine 1.4 Variants survey Type designation Part-No.: Nominal supply voltage VHF Transceiver single block Transmitter output Panel lighting Panel colour 13.75 V ³6W 13.75 V / 27.5 V black 13.75 V ³6W 13.75 V / 27.5 V black Green AR6201-(000) Article Nr.: 0610.321-910 VHF Transceiver single blockBlue-White AR6201-(002) Article Nr.: 0614.203-910 DV 14300.03/04 Issue 1 05/10 Page 1-3 AR6201 1.5 Technical data 1.5.1 Power supply data Nominal supply voltage Supply voltage range 13.75 V DC 9.0 V … 32.2V DC Emergency operation 9.0 V DC … 10.25 V DC Power consumption Power off state Reception mode Transmission mode £ 0.1 mA £ 140 mA £ 2 A TX mode m ³ 70 % £ 1.8 A @ 12 VDC; TX Carrier unmodulated £ 4 A @ 14 VDC; Antenna VSWR = 3:1 DC-Fuse internal 5 A (resettable) Dimming control 13.75 V DC or 27.5 V DC 1.6 General data Frequency range Frequency range 118.000 MHz to 136.975 MHz for 25 kHz 118.000 MHz to 136.990 MHz for 8.333 kHz Channel spacing 25 kHz or 8.333 kHz Nummber of channels 760 (25 kHz) / 2278 (8.333 kHz) Storage temperature range -55 °C to +85 °C Operating temperature range as per EUROCAE/RTCA ED-14E/DO-160E -20 °C to + 55 °C short-time + 70 °C Operating altitude as per EUROCAE/RTCA ED-14E/DO-160E 35,000 ft Vibration as per EUROCAE/RTCA ED-14E/DO-160E Cat.

After installation of the unit, measure the antenna tuning between the base of the antenna and the antenna connecting cable using a VHF reflection-coefficient meter (voltage standing wave meter). The VSWR (voltage standing wave ratio) over the complete frequency range of the unit shall be within 3:1. If this matching value is exceeded it indicates a mismatch, caused for example by an incorrect or unsatisfactory counterpoise, a cable with an impedance which deviates significantly from 50 Ohm or an incorrectly tuned antenna, or faults on the BNC connectors of the antenna cable. 2.13.2 Ground test with engine running. With the engine running at cruising speed check that the aircraft power supply is within the permissible tolerances at approximately 14 V. When performing a communication test, ensure that the distance from the ground station is as great as possible, at least 100 m. With the engine at cruising speed, the cabin noise of the aircraft should be only slightly transmitted and communication should be clear and distinct. Hold the microphone close to the lips while speaking. Activate the intercom function and carry out a speech test with the engine running at cruising speed. If necessary, adjust the IC volume (refer to the service mode). Switch on the squelch and check the squelch function. The threshold of the squelch can be set in the service mode . The sidetone volume can be adapted to pilots convenience. If necessary, adjust the sidetone volume (refer to the service mode). When using the loudspeaker, the sidetone should be adjusted to zero, so that no acoustic feedback occurs.

DV 14300.03/04 Issue 05/10 Page 3-15 AR6201 3.10 Safety instructions The following instructions must be followed for safe operation of the VHF transceiver: Ë Switch OFF the unit before starting or shutting down engines. Ë A speech test is to be performed before startup and it should be noted that if the speech test is carried out close to the ground station the results may be positive even if the antenna cable is broken or short-circuited. At a distance of 5 to 10 km no connection will be made. Ë Use a loud voice for speech communication and hold the microphone close to the lips. Otherwise cabin noise can be intrusive and make understanding difficult. Ë Use only microphones or headsets which are suitable for use in aircraft. In aircraft made of wood or synthetic materials or in gliders or helicopters, incoming radiation on the equipment antenna can affect the integrated amplifier of the microphone (feedback). This is noticeable in the ground station by whistling and/or heavy distortion. The described disturbances can occur in different ways on the different transmission channels.
