Radio receivers "Meridian RP-408" and "Meridian RP-308" from 1984 and 1990 produced the Kiev software named after SP Korolev. Meridian RP-408 (until 1986 Meridian-408) was created on the basis of the Selga-410 model. `` RP-408 Meridian '' is a small-sized, dual-band CB, DV superheterodyne assembled on a microcircuit, field-effect transistor, several resistors, capacitors, circuits and general radio nodes. The ranges LW - 148 ... 285 kHz, CB - 525 ... 1607 kHz. Sensitivity in the ranges of LW - 2.5 mV / m, CB - 1.3 mV / m. Adjacent channel selectivity for detuning at 9 kHz is at least 30 dB. The range of reproduced frequencies is 450 ... 4000 Hz. The maximum output power is 150 mW. The dimensions of the radio are 77x160x38 mm, its weight with batteries is 380 grams. Power is supplied from 3 elements A-316, with a total voltage of 4.5 V. In 1990, the receiver was renamed to `` Meridian RP-308 '', the design and electrical circuit of the model are the same.
