«Bekas-02E», «Bekas-07E», «Bekas» VHF/UHF airborne radio stations

BekasPurpose: The “Bekas” airborne radio stations are intended for radio communications with the instant selection of preset channels in the VHF/UHF frequency range at fixed frequencies and also for interference-resistant and secured communication both in the networks of the same type radio facilities and in the radio networks of the tactical command link (TCL) of Land forces, Navy and etc.
Operation modes: two-way radio communication with instant selection of preset channels, data traffic with the same type of airborne and airfield radio stations, control via a standard line from the control console or on-board computer, interference-resistant modes (FH-A, FH-B), automatic testing of serviceability with output of data to the control console, operations with a noise suppressor, retransmission, radio telephonic communication at fixed frequencies, technical masking mode, self-listening, tone call signal.
Component parts of a base delivery: transceiver, shock mount, control console, power amplifier, set of mounting components, SPTA-S set, in-line documentation set.

Particularities of the “Bekas” radios:
- possibility of use the radios both as autonomous ones and as a part of the aircraft command centers;
- presence in structure of the radios of an emergency receiver, which ensure listening watch at a frequency of 121.5 MHz or 243.0 MHz in the A3E mode and at a frequency of 156.8 MHz in the F3E mode;
- use of frequency-shift keying in the FH-A mode at a data transmission rate of 19.2 kbps;
- use of differential PM at a rate of 48 kbps in the FH-B mode;
- continuous operation time with TX:RX=1:5 time ratio is at least 24 h;
- possibility of joint operation in the FH-A mode with the radio networks of tactical command link of the Land forces, Navy and etc. At that, the main stock of radio facilities (presented below) is manufactured by Yaroslavl Radiowork Corporation:
- R-168-0.1UME/ R-168-0.1UM1E (handheld and vehicular);
- R-168-0.5UDE (handheld and vehicular);
- R-168-0.5UN-1E (manpack, vehicular and stationary);
- R-612 (vehicular and stationary versions, for Navy TCL);
- possibility of joint operation in the FH-B mode with airborne radio stations R-833, R-999;
- possibility of joint operation with airborne radio stations R-862M, R-863M.
