SOV - R-173 (radiostanice)

Determination: The radio station consists of a simplex receiver and a transmitter with frequency modulation. It is designed for two-way radio telephony communication between mobile means on the spot and on the move.
The radio station enables a connection without avoiding and tuning on any of the ten pre-prepared frequencies.
The radio operates on a 3m antenna. It is permissible to operate on a 1 and 2 m antenna, or an emergency antenna at closer distances. To increase the range it is possible to use a broadband VHF antenna placed on a table.
After proper selection of frequencies, simultaneous independent operation on a common antenna is possible when using a block of antenna filters:
- two rdst R-173
- rdst R-173 and radio receiver R-173P
The radio station allows operation from a talker, or without it, using a hood with a throat microphone.
Operation with a speaking device is possible via the amplifier of the throat microphone (R-173-16).

Procedure for tuning rdst R-173M (at least one antenna part must be fitted!):


1. Switch the PITANIJE to ON.
2. Select the channel (e.g. press button 1)
3. Toggle the USE - WRITE switch to the WRITE position. The display will
The display will light up with the currently tuned frequency.
4. Press the ZBROS button (erase the set frequency)
5. Use the number buttons to set the currently selected frequency in
rdst working range.
6. Switch RABOTA - WRITE to the RABOTA position
7. We can choose another channel and during tuning we follow the same procedure as
for the first channel. This way we set up to 10 default channels (in total)
8. We can broadcast
