FACILITIES FOR COMMUNICATION AND CONTROL FOR ALL KINDS OF WARSHIPS

R-612 VHF/UHF radio station

R-612
The R-612 radio station provides clear or encrypted with the aid of external system communication in the VHF/UHF frequency range between mobile and stationary objects of the navy tactical command link.
It is installed in the submarines, any surface vessels and Navy coastal objects.
The R-612 radio ensures communication with vessels at the international frequencies of marine service and with aircraft at the conterminous frequencies.
It provides communication within the limits of the United system of the Tactical command link.
Component parts (depending on version): from 1 to 6 of reception-transmission channels and microphone-telephone handset MTG-1, post, mains box, unit R-612AF-31 (switching device of two transceivers for their simultaneous operation into the common antenna), unit R-612AF-35 (amplifier of audio signals for loud speaker), unit R-612AF-29 (matching transformer of 50/75
Ω), unit R-612AF-20 (for operation both transceiver and HF radio into the common antenna), SPTA-S (single) set, in-line documentation set.
Delivery may be supplemented with the following units: HF/VHF AFD (antenna-feeder device), VHF/UFD AFD, VHF2 AFD, UHF2 AFD, combined AFD, unit for mating with ciphering equipment, RCC (remote control console), LFA, unit R-168-UVRD-O (for radio data input)
Operation modes: FF (fixed frequency, simplex or double simplex, scan receiving), FF with encryption, FH-100 (frequency hopping with 100 hops/s), adaptive communication (AC).
