Portable radio `` Banga-2 ''.
Portable radio receivers and radios on p / p.DomesticSince 1967 the portable radio receiver "Banga-2" has been producing the Riga Radio Plant named after Popov. '' Banga-2 '' is a class III superheterodyne radio receiver designed to receive broadcasting stations in the LW and MW bands on the internal magnetic and HF on the telescopic whip antennas. The receiver is analogous to the Banga model. Basic technical data: Ranges of received waves (frequencies); DV 2000 ... 735.3 m (150 ... 408 kHz). SV 571.4 ... 186.9 m (525 ... 1605 kHz) KB 24 ... 49 m (12.1 ... 5.95 MHz). Sensitivity in the ranges: DV 1.5 mV / m, SV 0.8 mV / m, KV 50 μV. Selectivity (with detuning ± 10 kHz) not less than 26 dB. Attenuation of the mirror channel, not less: DV, SV 20 dB, KV 10 dB. The intermediate frequency of the radio is 465 kHz. AGC action: when the RF signal at the receiver input changes by 26 dB, the voltage change at the receiver output is no more than 6 dB. Audio frequency band 350 ... 3500 Hz. Rated output power 100 mW. Power supply 6 elements of type 316. Power supply voltage 9 V. Quiescent current no more than 10 mA. The efficiency of the radio is maintained when the supply voltage drops to 5.6 V. The dimensions of the model are 190x110x62 mm. Weight 800 gr.
