The Radios "Meridian RP-408" and "Meridian RP-308" from 1984 and 1990 produced the Kiev software named after SP Korolyov. Radio '' Meridian RP-408 '' (until 1986 '' 'Meridian-408' ') was created on the basis of the radio receiver' 'Selga-410' '. '' RP-408 '' Meridian is a small-sized, dual-band SV, DV superheterodyne, assembled on a single multifunctional chip such as K174XA10, a KP-303 or KP-302 type transistor, several resistors, capacitors, circuits and common radio centers. The ranges of DV 148 ... 285 kHz, CB 525 ... 1607 kHz. Sensitivity in the DV ranges - 2.5 mV / m, SV - 1.3 mV / m. The adjacent channel selectivity with 9 kHz detuning is at least 30 dB. The frequency range is 450 ... 4000 Hz. Maximum output power 150 mW. The dimensions of the radio receiver are 77Ñ…160Ñ…38 mm, its weight with batteries is 380 grams. Power is supplied from three A-316 elements, with a total voltage of 4.5 V. In 1990, the receiver was renamed to RP-308 Meridian, the design and electrical circuit of the model remained the same.
