Miniature radio `` Micro-S ''.

Portable radio receivers and radios on p / p.DomesticThe miniature radio "Micro-S" has been in production since 1969. There is practically no information on the receiver, the year of manufacture is also in question, the manufacturer has not been established. From the photographs, it can be assumed that this is a DV, SV superheterodyne, built on the basis of the "Micro" receiver, the board from which is used to amplify IF signals, detect and amplify LF signals. For each of the ranges, a separate local oscillator with a contour, a shifter and a body kit is used. A separate magnetic antenna is used for each band. The range switching (power supply of the GPA) is carried out by the KPE adjustment knob. The selection at the intermediate frequency of 465 kHz is carried out by an electromechanical filter, from the output of which the signal is fed to the input of the Micro receiver board. The output stage of the low-frequency amplifier, as in the "Micro" radio receiver, is also loaded here on the head low-impedance telephone of the "TM-2M" type.
