Since 1965, the portable transistor radiogram "Rest" has been produced by the Kyshtym Radio Plant. ,d79f3353813f458ef00a8442f9b7b2b6Radiola class 2 with self-powered ''Rest'' was created on the basis of the chassis of the radiola ''Efir-M'' and is a desktop-portable type superheterodyne assembled on nine transistors and combined with an electronic control unit. ,d79f3353813f458ef00a8442f9b7b2b6Radiola is intended for reception in the ranges of DV, SV and HF on external and internal magnetic antennas and playback of recordings. ,d79f3353813f458ef00a8442f9b7b2b6In the HF band, reception is carried out from an external antenna. ,d79f3353813f458ef00a8442f9b7b2b6The HF range is divided into 3 sub-bands. ,d79f3353813f458ef00a8442f9b7b2b6EPU has 3 speeds of disk rotation. ,d79f3353813f458ef00a8442f9b7b2b6Sensitivity when operating from a magnetic antenna: LW 1.2 mV/m, SW 0.6 mV/m. ,d79f3353813f458ef00a8442f9b7b2b6From an external antenna: LW - 65 μV, MW - 50 μV, HF - 30 μV. ,d79f3353813f458ef00a8442f9b7b2b6Adjacent channel selectivity 36 dB. ,d79f3353813f458ef00a8442f9b7b2b6Mirror channel attenuation: LW - 40 dB, MW - 30 dB, SW - 15 dB. ,d79f3353813f458ef00a8442f9b7b2b6The IF is 465 kHz. ,d79f3353813f458ef00a8442f9b7b2b6The band of reproducible frequencies during reception is 150 ... 4000 Hz, when playing a recording - 150 ... 10000 Hz. ,d79f3353813f458ef00a8442f9b7b2b6Rated output power 500 mW. ,d79f3353813f458ef00a8442f9b7b2b6Power supply 6 A-373 batteries. ,d79f3353813f458ef00a8442f9b7b2b6The current consumed by the receiver in the absence of a signal is 14 mA. ,d79f3353813f458ef00a8442f9b7b2b6The operation of the receiver is maintained when the supply voltage drops to 4 volts. ,d79f3353813f458ef00a8442f9b7b2b6The duration of the receiver at an average volume from the A-373 elements is about 200 hours. ,d79f3353813f458ef00a8442f9b7b2b6Sensitivity from the pickup at a nominal power of 120 mV. ,d79f3353813f458ef00a8442f9b7b2b6Model dimensions 320x340x160 mm. ,d79f3353813f458ef00a8442f9b7b2b6Weight 7.8 kg. ,d79f3353813f458ef00a8442f9b7b2b6The detachable closing top cover of the radiola is also the acoustic system of the radiola. ,d79f3353813f458ef00a8442f9b7b2b6A small batch of radios was produced complete with an external power supply, so this model was called "Radio with transistors" Rest "with universal power supply.",d79f3353813f458ef00a8442f9b7b2b6,null,ru,null,null,null,null
