- Description
- An automatic direction finder (ADF) receiver. This ADF is a remotely mounted ADF receiver that provides relative bearing between the aircraft and the selected ground station. It also provides an output to the aircraft audio system for verifying the station identifier and for AM reception. It is primarily used in civil aircraft. The ADF receiver is completely solid state and contains no moving parts. This receiver contains all frequency, tuner, instrumentation and logic circuits required to convert the radio frequency input from the antenna into bearing information and an audio output when used in the ADF function, or into an audio output when operating in the ANT function. A TONE mode is provided for CW reception. The ADF Receiver contains an AC synchro driver board as part of the front panel assembly. It allows for detection to demodulate bearing signal for reduced bearing errors and safety hazards caused by adjacent channel signals. The ADF eliminates all electromechanical components found in older ADF systems and features modular construction for streamlined bench test service. Also, the ADF receiver employs conventional three-wire AC synchro outputs for use with standard RMIs. An optional dual element antenna, the ANT-60B, is also available to further simplify the installation of dual ADF systems. This antenna combines both loop and sense functions for two ADF systems within one housing. The ADF Receiver is constructed as a 3/8−ATR low−profile case that measures 89 (h) × 91 (w) × 356 (l) mm (3.5 (h) × 3.6 (w) × 14.0 (l) in). All dimensions are nominal. The receiver weighs 1.91 kg (4.2 lb) maximum and is mounted in a 390R−19 or UMT−12 mount with or without vibration isolators. The unit is painted black to conform to requirements of FED−STD−595.
