Belka-DSP receiver is designed for listening to radio stations with AM, NFM and SSB modulation as well as to CW signals at frequency range 3.5 – 30 MHz.
Case size – 85x50x20mm, low weight – about 100 g. High sensitivity is realized when receiving on a telescopic antenna. Despite, Belka-DSP works excellent with full-size antenna.
It is possible to adjust the audio highpass from 2.4 to 4.7 kHz as well as lowpass from 50 to 300 Hz. In telegraph mode the frequency band is about 300 Hz with regulated pitch from 500 Hz to 1 kHz.
The settings of the favorite radio stations can be stored in any of 32 memory cells.
There is no built-in speaker, but there is a fairly powerful bridge mode audio amplifier that provides sufficient volume when working on an external speaker or headphones.
The built-in LI-Ion battery allows to work on it for about 24 hours.
In addition to the built-in battery the receiver can also work from an external DC voltage source of 5 V.
