The radio receiver "Micro" was produced by the Zelenograd plant "Angstrem" since the beginning of 1965, and since the autumn of 1965 by the Minsk radio plant. The radio receiver is designed to operate in the LW and MW ranges. The receiver sensitivity is 35 mV/m. Selectivity is 6...10 dB. Output power is 0.5 mW. Power is supplied by a 1.2 V battery. Current consumption is 5 mA. The receiver dimensions are 45x30x13 mm, weight is 27 grams.
The receiver has a power switch, settings and a range switch. The receiver is assembled according to a direct amplification circuit on 6 transistors and is loaded onto a TM-2M telephone. In the radio receiver, six layers of different materials are applied to a board made of glass-ceramic polished to a high purity class, under high vacuum through special stencils, from which resistors, conductors, contact pads, capacitor plates and insulation are formed. Transistors are mounted on a separate board made of foil-clad fiberglass.
The "Micro" radio receiver was manufactured for sale in the USSR, and in the export version for a number of socialist countries under the names "Micro" and "Astrad Orion". The first releases of the "Micro" receiver had other frequency ranges and better sensitivity. Since 1967, the Minsk Radio Plant has been producing its receiver under the name "Micro-M".
