Radio Station

The radio station is equipped with a noise and pulse interference suppressor. The power consumed from the locomotive-borne mains is 50 W, maximum, in the standing mode and reception mode and 100 W in the transmission mode. The guarantee operation life is 2 years. The resource is 10 years. The radio station has been d

The radio station has been developed, taking into account the experience of use of radio stations of the old stock and provides the following functional capabilities:

  • light and audio signalling of the call of 700+1 Hz, 1000+1 Hz, 1400+2 Hz, 2100+2 Hz;
  • automatic switching-off of the transmitter when transmission lasts for more than 1 min with audio indication of switching-off;
  • constant light indication of channel serviceability when operating for transmission and for reception;
  • built-in test of serviceability of the whole radio station;
  • interchangeability of power supply units, manipulators, internal loudspeakers unit and cables of SW and FM radio stations;
  • providing of qualitative communication with all radio stations operating in the set band;
  • protection of the transmitter against a short circuit and opens of the antenna.
Overall dimensions, mm and weight, kg of constituent parts:
transceiver (TR) 260х230х130 5.0
power supply unit 260х230х130 3.0
control panel (CP) 1.0
antenna-matching device (AMD) 145х250х165 2.0

Basic advantages of the radio station are:

  • modern technology of surface-mounting design;
  • possibility of a separate delivery of SW and FM radio stations;
  • simplicity and comfort in control;
  • use of reliable components;
  • disposition of SW and FM transceivers in one body;
  • use of modern microprocessor equipment and SMD technologies.
