Purpose: TsRRS R-419 L1 is designed to organize independent radio relay communication lines, as well as to tap off channels from multichannel radio relay, tropospheric and wire communication lines.
The station provides work on linking lines of 6 channels of PM equipment of the P-330-6 with the ability to receive the P-340 GMN equipment on the PM channels on communication lines up to 120 km long in the range 390-645 MHz, and in digital modes on communication lines up to 400 km in the range of 390-645 MHz and up to 1500 km in the range of 1550-1850 MHz.
Work on the radio relay station P-419 L1 in the terminal and relay modes
At the station, prepared for work in analog mode
- Turn on the station and check for power;
- check the work of both half-sets of the section "for yourself";
- make electrical measurements of parameters of connecting lines;
- get in touch with the correspondent with two semi-sets in terminal mode, measure the stock of the HF level;
- adjust the receiving levels of the group paths and the residual attenuation of the PM channels;
- measure the frequency response of the residual attenuation of the two PM channels of each half-set, the noise level in the channels, estimate the noise saturation of the channels and pass them to the specialized equipment for classifying or cross;
- put the station in the relay mode and make sure that the connection is passing;
- make the necessary entries in the hardware log.
