1 Description and Performance
1.1 Purpose
The radio, carried by the personnel, is designed to provide tactical communications
both in stationary and battlefield conditions.
The radio provides the possibility to transmit and receive voice and data (digital
information) while operating on the fixed frequencies (non-ECCM mode) and in the ECCM
mode.
ECCM mode of operation is intended to provide radio communication in conditions of
hostile interference setup. Protection from hostile interference is done using the frequency-
hopping spread spectrum (FHSS) mode. Frequency hopping is 312.5 per second. In the
FHSS mode the radio is interoperable with radios of the same type or other radios that are
compatible on data communications protocol in aggregate bandwidths.
While operating on fixed frequencies the radio is compatible with the older radio
systems.
The radio operates in the following modes:
- single-frequency simplex (transceiving on the same frequency while operating on
fixed frequencies, or tranceiving on the same set of radio data in the FHSS mode);
- half-duplex (receive on the one frequency and transmission on the another
frequency while operating on fixed frequencies, or receive on the one set of radio data and
transmission on the another set of radio data in FHSS mode);
- single-frequency simplex (half-duplex) in one radio network and stand-by receive in
the anoter one;
-stand-by power saving receive;
- radiodata entry.
While operating on fixed frequencies and in the FHSS mode the radio provides
transceiving of the following:
- voice information from the telephone headset or directly from the tranceiver;
- data with the rates of 1200, 2400, 4800, 9600 bps from the PC or other devices
at the RS-232 interface;
- SMS messages;
- individual (selective), circular (group) and tone calls.
