Portable transistor radio "Rest".
Radiols and receivers p / p stationary.DomesticThe portable transistor radio "Rest" has been produced by the Kyshtym Radio Plant since 1965. A class 2 self-powered radio "Rest" is created on the basis of the chassis of the "Efir-M" radio and is a desktop-portable superheterodyne, assembled on 9 transistors and combined with an EPU. Radiola is designed for reception in the LW, MW and HF bands on external and internal magnetic antennas and for reproduction of a gramophone record. In the HF range, reception is from an external antenna. The HF band is divided into 3 sub-bands. EPU has 3 speeds of rotation of the disk. Sensitivity when operating from a magnetic antenna: at DV 1.2 mV / m, SV 0.6 mV / m. From an external antenna: DV - 65 μV, SV - 50 μV, HF - 30 μV. Adjacent channel selectivity 36 dB. Attenuation of the mirror channel: LW - 40 dB, MW - 30 dB, HF - 15 dB. The IF is 465 kHz. The band of reproducible frequencies when receiving 150 ... 4000 Hz, when playing a gram recording 150 ... 10000 Hz. Rated output power 500 mW. Power supply of 6 А-373 batteries. The current consumed by the receiver in the absence of a signal is 14 mA. The operation of the receiver is maintained when the supply voltage drops to 4 V. The duration of the receiver at an average volume from the A-373 elements is about 200 hours. Pickup sensitivity at 120 mV rated power. Dimensions of the model are 320x340x160 mm. Weight 7.8 kg. The detachable closable top cover of the radio is also the sound system of the radio. A batch of radios was produced complete with an external power supply unit, so this model was called "Radiola on transistors" Rest "with universal power supply".
