Since 1978, the Yunost KP-101 radio receiver from the DIY kit has been producing the 1st Moscow Instrument-Making Plant. Radio kit ''Yunost KP-101'' is designed to assemble an transistor radio receiver according to the direct amplification reflex circuit 2-V-3 on four transistors operating in the medium wave range of 200 ... 550 m (520 ... 1600 kHz). Reception of broadcasting stations is carried out on an internal ferrite antenna. The push-pull output stage of the power amplifier provides a nominal output power of 130 mW. To increase the sensitivity and selectivity of the adjacent channel, a positive feedback was introduced into the circuit. The radio receiver is powered by a 9 volt DC. As a source, battery 6F22 type can be used. The average value of the consumed current is 16 mA. The radio receiver is assembled in a small-sized, plastic case. Parts are mounted on a printed circuit board.
