Since 1965, the Orbita portable transistor radio receiver has been produced by the AS Popov Riga Radio Plant. ,86e6f450b8cc469628ba70bf2947b049The Orbita class IV radio receiver is designed to operate in the medium and short (25 ... 75 m) wave bands, and one internal magnetic antenna is used for reception on both bands. ,86e6f450b8cc469628ba70bf2947b049The Orbita receiver was awarded a quality mark for its high electro-acoustic and operational qualities and modern external design. ,86e6f450b8cc469628ba70bf2947b049The receiver is assembled according to a superheterodyne circuit with 8 transistors and 2 semiconductor diodes. ,86e6f450b8cc469628ba70bf2947b049Listening to programs is carried out on the internal loudspeaker 0,1GD-6 or external miniature telephone TM-4. ,86e6f450b8cc469628ba70bf2947b049The radio is powered by four A-316 type elements connected in series. ,86e6f450b8cc469628ba70bf2947b049The sensitivity of the receiver in the CB and KB ranges when receiving on an internal magnetic antenna is 1 mV / m, the selectivity in the adjacent channel is 20 dB, the attenuation of the mirror channel in the KB range is 10 dB, CB is 20 dB. ,86e6f450b8cc469628ba70bf2947b049IF 465 kHz. ,86e6f450b8cc469628ba70bf2947b049The AGC system of the radio receiver provides, when the input voltage changes by 26 dB, the output voltage changes by 8 dB, the volume is adjusted within 30 dB. ,86e6f450b8cc469628ba70bf2947b049The frequency response in terms of sound pressure with its non-uniformity of 14 dB is 450 ... 3000 Hz, average sound pressure 0.2 N / m, rated output power 100 mW, quiescent current 8 ... 9 mA. ,86e6f450b8cc469628ba70bf2947b049The efficiency of the receiver is maintained when the supply voltage changes within 6.5 ... 3.8 V. The dimensions of the radio receiver are 150x80x35 mm, its weight is 340 g (without batteries).,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
