VHFUHFfor aircraft

The airborne communication transceiver LUN 3520 is a VHF–UHF transceiver designed for the communication between aircraft by means of the built-in intercom for the communication between the aircraft crew and for the communication with the ground means of air traffic control. It works in channel steps of 25 kHz and 8.33 kHz. The basic assembly is composed of the transmitter-receiver bank, spring-loaded frame, control box, switch box and the low frequency block. The transceiver is implemented as a system of separate blocks, the combination of which makes it possible to achieve the optimum application configurable for any type of aircraft, helicopter or air traffic control unit. Its technical parameters meet ICAO regulations and NATO standards. With its characteristics and parameters, it is comparable with the transceivers used in the armies of NATO member states. It is often used for the modernisation of aircraft and helicopters manufactured in the Czech Republic or Russia. For two-way simplex phonic radio communication The transmitter-receiver block is a separate block of the airborne communication transceiver LUN 3520. It is manufactured in several versions. It contains the power supply, receiver, transmitter, frequency synthesizer, remote control circuits, testing and emergency receiver circuits. It allows two-way simplex phonic radio communication on any channel in the band of VHF (117.975-155.975) and UHF (220.000-399.975) MHz. The channel step in the VHF band is 25 kHz and 8.33 kHz, and 25 kHz in the UHF band. The transceiver block is installed in a spring–loaded frame. Control Boxes Remote control of the transceiver
