Army radio `` R-323 '' (Digit).
Receiving and transmitting radio equipment.The army radio "R-323" (Digit) was produced in small series since 1961, and in series since 1963. Designed to receive signals with AM and FM modulation, as well as telegraph. It is assembled according to the superheterodyne circuit with 3 conversions on 28 lamps (5 lamps 1Ж29Б and 23 lamps 1Ж24Б). For power supply from 220 or 127 V alternating current, the receiver is equipped with a separate external stabilized rectifier "VS-2.5M". Main technical characteristics: Range of received frequencies 20 ... 100 MHz (4 sub-bands). The frequency setting error is 10 KHz. Frequency shaping / setting smooth local oscillator (LC generator). Frequency display - optical scale (resolution 10/20 KHz). Sensitivity in AM (narrow / wide band) 3/5, FM - 2.5, CW 1 μV. Attenuation along the mirror channel is not less than 800 times. Bandwidth 8, 25, 85 KHz. Intermediate frequencies 9 MHz; 2.86 MHz; 473 KHz. The output voltage of LF on one pair of low-impedance telephones is 4.5 V. THD is 10%. Supply voltage 2.5 V. Operating temperature range -50 + 50 ° C. Dimensions 225x270x370 mm. Weight 4.5 kg.
