Transceiver R-143

R-143 provides:

* two-way simplex communication with using USB (upper side band) and suppression of the carrier and LSB (lower side band);

* two-way simplex communication in AT telegraph mode;

* carrier telegraphy at a nominal frequency with frequency shift (250±50)Hz relative to the carrier;

* joint operation on transmission using SR (speed of response) equipment with speed up to 150 bauds in FT (Frequency Telegraph) mode;

* tonal call with audio reception at frequency (1000 +500/ -200) Hz;retuning time (after setting of rated frequency by the decade switch)

is not more 20 -30 s;

* telephone communication at a set frequency from Field Telephone TA-57-y (TA-57) that is connected to the radio set by a double-wire

field cable up to 500 m.

R-143 is made in the following versions:

* YAG 1.201.034-01 - man-pack radio set that ensures independent operation. Power supply of the radio set is carried out by storage battery;

* YAG 1.201.034-02, -03, -04,-08 - mobile radio sets;

* YAG 1.201.034-05, -09 - fixed radio sets.1. Frequency range, MHz
