Portable radios "Selga-410" and "Selga-309" from 1983 and 1985 were produced by the Riga Company "Radiotekhnika" and the Kandava Radio Plant. The ''Selga-309'' radio receiver was created on the basis of the ''Selga-410'' radio receiver, which was developed and released as an experimental series back in 1983. Both radios are the same. The ''Selga-309'' radio receiver is a dual-band LW and MW superheterodyne, assembled on a K174XA10 multifunctional microcircuit, a KP-303 field-effect transistor and several radio components. The plant also produced a small batch of radio receivers on a discrete components basis. Main characteristics of RP: Ranges: LW- 148...285 kHz, MW - 525...1607 kHz. Sensitivity in the ranges: LW 2.5 mV/m, MW 1.3 mV/m. Selectivity 30 dB. The range of reproducible frequencies is 450...4000 Hz. Maximum output power 150 mW. The dimensions of the receiver are 74x158x37 mm, its weight with np batteries is 250 gr. The radio is powered by three elements - A-316, with a total voltage of 4.5 V.
