RADIO STATION P-173M

RADIO STATION P-173M

Ultra-short wave simplex radio station Р-173М is intended for maintaining two-way communication among vehicles both stationary and mobile.

FUNCTIONAL POSSIBILITIES:

Radio Station Р-173М provides the following functions:

1) speech reception/transmission both in analog and digital mode;

2) speech masking in digital mode with possibility to change protection key from PC;

3) operation with speaking devices;

- with throat microphones (ICS mode);

- with terminal equipment (TERM EQ mode);

- with intercom and switching equipment ABCK 1;

4) operation with exterior unit – GPS;

5) operation with exterior terminal (personal computer) through RS232 interface;

In analog mode radio station Р-173М provides the following functions:

speech transmission/reception with frequency modulation and data with frequency-shift keying.

In digital mode radio station Р-173М provides the following functions:

1) file transmission/reception at rate up to 10 МByte (with receipt acknowledgement) in a mode without voice priority:

a) at operating frequency at the rate of 12,8 кBit/s;

b) at a pre-selected frequency (auxiliary channel) with further return to the operating frequency at the rate of 12,8 кBit/s;

2) file transmission/reception at rate up to 10 МByte (with receipt acknowledgement) in a mode with voice priority (C4I) at the operating frequency at the rate of 10 kBit/s;

3) transmission/reception of address short message with acknowledgement of receipt;

4) transmission of short messages in circular mode with acknowledgement of receipt;

5) operation with exterior unit GPS enabling performance of the following functions:

а) determination of object’s own coordinates;

b) request of coordinates of remote object under individual number;

c) request of coordinates of remote objects (up to 15 units) in circular inquiry mode;

d) periodic transmission of own coordinates.

6) determination of radio station parameters from PC.

Radio station is powered by voltage of 27 V from DC mains.

Radio station can be completed with additional power supply units:

- to be powered from 12 V direct-current mains;

- to be powered from 220 V alternating-current mains.

The Radio Station remains serviceable under the environment temperature from minus 40°С to plus 50°С.
