Radiola network lamp "Ural-5".
Network tube radiosDomesticThe network tube radio "Ural-5" has been produced by the Ordzhonikidze Sarapul Radio Plant since 1967. Radiola is designed to receive in the following ranges: DV, SV, KB-2 - 75.9 ... 40.5 m, KB-1 - 32.0 ... 24.8 m and VHF-FM. Sensitivity with an external antenna in the LW, SV ranges of 20 µV, KV 50 µV, on VHF-FM 5 µV. Sensitivity with a magnetic antenna in the ranges DV, SV 0.6 ... 1.5 mV / m, in the "local reception" position 0.4 ... 0.8 mV / m. IF in the AM path 465 kHz, in the FM path 6.5 MHz. The bandwidth of the AM path with a signal attenuation of 6 ... 8 dB in the position of a narrow band of 5 kHz, a wide band of 11 kHz, local reception of 15 kHz. The bandwidth in FM is 130 ... 180 kHz. Selectivity on the adjacent channel at 10 kHz detuning in - LW, MW 60 dB. The slope of the slopes of the resonant characteristic in the VHF-FM range is 0.3 dB / kHz. Selectivity on the mirror channel in the ranges DV 65 dB, SV 46 dB, KB-1, KV-2 20 dB, VHF-FM 28 dB. AGC provides a change in the signal at the output of the radio by 12 dB when the signal at the input changes by 40 dB. The rated output power of the ULF is 2 W, the maximum is 3.5 W. Sensitivity from the pickup jacks 200 mV. The range of reproducible frequencies in the AM path in the position "narrow band" 80 ... 4000 Hz, "wide band" 80 ... 6000 Hz, "local reception" 80 ... 8000 Hz. FM path 80 ... 12000 Hz, recording 80 ... 10000 Hz. Separate tone control for bass and treble. The background level from the amplifier input is -56 dB. An EPU type II-EPU-40-127 is installed in the radio, which has four speeds: 78, 45, 33, 16 rpm, semi-automatic switching on and off, microlift. An EPU type III-EPU-20-3-127 was also installed without a speed of 16 rpm. Power consumption from the network during radio reception is 55 W when listening to a record 65 W.
