Radiola network lamp `` Belarus-103L ''.
Network tube radiosDomesticThe network tube radio "Belarus-103L" has been produced since 1968 at the Minsk Radio Plant. The radiola consists of a ten-lamp receiver of the first class, designed to receive radio stations in the range of DV 150 ... 408 kHz, SV 525 ... 1605 kHz, KB3 3.95 ... 7.6 MHz, KB2 9.3 ... 9, 8 MHz, KB1 11.6 ... 12.1 MHz and VHF 65.8 ... 73 MHz and three-speed II-EPU-15A, with an automatic switch and a microlift. Sensitivity with an external antenna in the DV, SV, HF ranges of 50 µV, in the VHF-FM range of 8 µV. Sensitivity with a magnetic antenna in the LW, MW ranges of 500 µV / m, in the "local reception" position 0.7 mV. The intermediate frequency of the AM path is 465 kHz and the FM path is 6.5 MHz. Adjacent channel selectivity at 10 kHz detuning - 60 dB. In FM, the average slope of the slopes of the resonant characteristic is 0.25 dB / kHz. The bandwidth on the IF in the AM path in the "narrow band" position 4 kHz, "wide band" 11 kHz, "local reception" 14 kHz, in the FM path the bandwidth is 160 kHz. The AGC system of the radio provides a change in the output signal by 10 dB, when the input signal changes by 60 dB. The nominal output power of the amplifier is 4 W, the maximum is 7 W, the reproducible frequency range is 80 ... 12500 Hz. The range of tone control is 12 dB. The sensitivity of the amplifier from the jacks of the tape recorder at a nominal output power of 150 mV, the background level is -54 dB. The radio acoustic system consists of 3 2GD-19 loudspeakers. The radio is powered by an alternating current. Power consumption from the network is 100 watts. The dimensions of the radio are 790x380x355 mm, its weight is 27 kg.
