Technical description

Р-173М radio set is a VHF reception-transmission, simplex with frequency modulation radio set that provides two-way radio communication between objects while movement and at stop.

Р-173М radio set operates in analog and digital modes and provides the following: 

In analog mode:

  • voice and data reception and transmission with frequency modulation.

In digital mode:

  • files reception/transmission up to 10 Mbites (with reception conformation) in mode without voice priority:
    - on operating frequency with rate 12,8 kBit/sec;
    - on pre-set frequency (on standby channel) with the following return to the  operating frequency with rate 12,8 Mbit/sec;
  • files reception / transmission up to 10 Mbites (with reception confirmation) in voice priority mode (C4I) on operating frequency with rate 10 kBit/sec;
  • reception and transmission of short messages with reception confirmation;
  • transmission of short messages in circular mode with reception confirmation;
  • radio set parameters setting from PC.

 

Р-173М radio set provides searchless and not tunable communication on one of ten pre-selected frequencies.
Р-173М radio set provides operation on whip antennas 3m, 2m or 1m high, wide-band VHF and emergency antennas. While operation on movement whip antenna 2m is used as the main one.

When appropriate frequency choice radio set provides joint independent operation on:

  • common whip antenna using unit Р-173-14 (antenna filters unit):
    - of two radio sets Р-173М;
    - radio set Р-173М and radio receiver Р-173ПМ;
  • common whip antenna using unit AMD (antenna matching device) from set of HF radio set P-134:
    - radio set Р-173М and HF radio set Р-134;

While operation with analog signals all versions of radio set provide the following operation modes:

  • Intercom system mode:
    - operation with equipment of integral connection and commutation АВСК1, P-174;
    - operation with intercom system P-124 using laryngophone amplifier (unit P-173-16);
    - operation using laryngophone gear;
  • Terminal equipment mode (TE mode):
    - operation with unified equipment of integral connection and communication (ЯГ1.600.000 (UKA), АВСК «Zvezda» and so on);
    - operation with an external terminal (PC) via interface RS232.
