Radio stations "RSO-5" and "RSO-5M".

Receiving and transmitting radio equipment.The radio stations "RSO-5" (Polosa) and "RSO-5M" were produced since 1960 and 1967. RSO-5 is a tube, portable, single-band radio station designed for non-search simplex telephone and telegraph communication with similar radio stations operating on the upper sideband. It was used for radio communication in agriculture and forestry, on the construction of oil and gas pipelines, highways and railways, power lines, on water transport lines, during geological prospecting and in other areas of the national economy. The radio station consists of a transceiver unit and a power supply unit. Range: 1.6 ... 6 MHz. Channels - 4 (quartz). Power sources: mains, battery, foot drive dynamo. Supply voltage: 127/220 or 12 V. Power consumption: reception (network) 18 W, reception (battery) 12 W, transmission (network) 100 W, transmission (battery) 90 W. Communication range: up to 200 km. Connected antenna type: inclined beam with a length of 10-12 m and a suspension height of 4-6 m. Output power: CW - 5 W, SSB - 7 W. Sensitivity: 8 μV. The radio station "RSO-5M", except for the replacement of radio components with modern ones and minor improvements in performance characteristics, does not differ from the one described.
