Since 1967, the portable radio Banga-2 has produced the Popov Radio Plant of Riga. '' Banga-2 '' is a class III superheterodyne radio receiver designed for receiving broadcasting stations in the Far East and Main bands on an internal magnetic and KV to a pin telescopic antenna. The receiver is an analogue of the model "Banga". Main 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 of: DV 1.5 mV / m, SV 0.8 mV / m, KV 50 mV. Selectivity (at a mismatch on ± 10 kHz) not less than 26 dB. Attenuation of the mirror channel, not less: LW, MW 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 not more than 6 dB. The band of sound frequencies 350 ... 3500 Hz. Rated output power 100 mW. Power supply 6 elements of the type 316. The voltage of the power source 9 V. The quiescent current is not more than 10 mA. The efficiency of the radio receiver is maintained when the supply voltage drops to 5.6 V. The dimensions of the model are 190x110x62 mm. Weight 800 gr.
