Radio Set "Berkut-M" for 1.201.015

"BERKUT-M" offers operation under the following conditions:

-    temperature from minus 50°C to 60°C at relative air humidity up to 98% when temperature is 35°C;;

-   at impact loads with acceleration 20g with impulse duration 5-15m/s;

-   at vibration loads with acceleration 5g within 5-500Hz.

BERKUT-M" provides the following types of work in simplex and two-frequency simplex modes:

-   telephony with single-side band modulation on upper or lower side band (radiation class A3J);

-   amplitude telegraphy with on-off keying of the carrier (radiation class A1);

-   frequency telegraphy with FSK (frequency-shift keying)with carrier frequency shift ±250Hz (radiation class F1);

-   telegraphy, 150bit/s min, FSK with carrier frequency shift ±250Hz (QA-quick action) and ±100Hz (adaptation of radio-

network) with automatic telegraphy (radiation class F1);

-   scanning reception.

The radio set's control is provided by integral microcomputer.
