Stationary transistor radio `` Ausma ''.
Radiols and receivers p / p stationary.DomesticAusma - dawn in Latvian. The stationary transistor radio receiver "Ausma" in 1962 as an experimental batch was produced by the AS Popov Riga plant. "Ausma" became the first domestic desktop transistor radio receiver with VHF range and universal power supply. In comparison with the previously produced models, the receiver has better sounding, stability of parameters when the power supply is reduced, the ability to receive FM stations. The reception of DV and SV stations is carried out on a rotary magnetic antenna, on VHF on an external one. The receiver is powered by 9 V batteries or from the mains. Power consumption from the network is 5 W. The rated output power on the 1GD-3 loudspeaker depends on the power supply: in battery mode 150 mW, in mains mode 500 mW. Sensitivity with an external antenna for DV, SV - 20 ... 100 μV, VHF 2 ... 10 μV. When the magnetic antenna is operating on DV, SV - 0.2 ... 0.8 mV / m. Selectivity in the AM path 30 dB, FM 36 dB. IF 465 kHz and 8.4 MHz. The frequency response in terms of sound pressure, for DV, SV - 120 ... 6000 Hz, FM - 120 ... 12000 Hz. Distortion factor in the AM path 6%, FM 4%. The parameters are stable when powered by batteries and mains. When the power supply is reduced to 6.3 V, the sensitivity does not change, but the output power decreases and the THD increases. Receiver body made of wood, with dimensions 560x265x245 mm. Weight with batteries 8.5 kg.
