Since 1983 and 1985 portable radio receivers "Selga-410" and "Selga-309" have been produced by the Riga PO "Radiotekhnika" and the Kandavsky radio plant. ,86e6f450b8cc469628ba70bf2947b049The Selga-309 radio receiver was created on the basis of the Selga-410 radio receiver, which was developed and produced by an experimental series back in 1983. ,86e6f450b8cc469628ba70bf2947b049Both radios are the same. ,86e6f450b8cc469628ba70bf2947b049The Selga-309 radio receiver is a dual-band DV and SV superheterodyne, assembled on a K174XA10 multifunctional microcircuit, a KP-303 field-effect transistor and several radio components. ,86e6f450b8cc469628ba70bf2947b049The plant also produced a small batch of radios on "loose" basis. ,86e6f450b8cc469628ba70bf2947b049The main characteristics of the RP: Ranges: DV - 148 ... 285 kHz, SV - 525 ... 1607 kHz. ,86e6f450b8cc469628ba70bf2947b049Sensitivity in the ranges: DV 2.5 mV / m, CB 1.3 mV / m. ,86e6f450b8cc469628ba70bf2947b049Selectivity 30 dB. ,86e6f450b8cc469628ba70bf2947b049The range of reproducible frequencies is 450 ... 4000 Hz. ,86e6f450b8cc469628ba70bf2947b049Maximum output power 150 mW. ,86e6f450b8cc469628ba70bf2947b049The dimensions of the receiver are 74x158x37 mm, its weight with batteries is 340 g. ,86e6f450b8cc469628ba70bf2947b049The radio is powered by three elements - A-316, with a total voltage of 4.5 V.,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
