The Belka-DSP radio receiver is designed to receive radio stations with amplitude, frequency and single-band modulation, as well as telegraph signals at short waves in the frequency range 3.5 – 30 MHz.
One of the main features of the radio receiver is its small size – 85x50x20 mm in body and low weight – about 100 g. This makes it very convenient in traveling conditions. Also, high sensitivity is realized when receiving on a complete telescopic antenna.
It is possible to adjust the frequency band both from above, from 2.4 to 4.7 kHz, and from below from 50 to 300 Hz. In telegraph mode, the frequency band is constant, about 300 Hz, and its center is regulated from 500 Hz to 1 kHz.
The settings of the favorite radio stations can be stored in any of 32 memory locations.
The receiver does not have a built-in speaker, but there is a rather powerful VLF bridge that provides sufficient volume when working with an external speaker, speaker or headphones.
The built-in LI-Ion battery lasts for 24 hours of total operating time on the headphones.
In addition to the built-in battery, the receiver can also work from an external DC voltage source of 5 V.
