HK2000 radio equipment of HF range
Полное описание

The HK2000 are a generation of universal radio stations of the high frequency range (HF). These radio stations allow for automatic two-way adaptive radio communication on routes over small, medium and long distances, support traditional modes of operation (telephone, telegraph), as well as provide data transmission over a radio channel.

The implementation of additional service functions is done only by downloading the required software version without upgrading the hardware of the equipment.

All radio station modules have a compact design and can be installed on a 19-inch rack.

All radio stations of the 2000 series can interact with external wireline and wireless telecommunication systems of various types, both with classical (ATM, UATMS) and with specialized (for example, TETRA, MPT1327) existing radio systems of different departments (police, emergency, etc.).

For operation with different types of antennas, radio stations of the 2000 series can be equipped with automatic antenna-matching devices.
