The radio receiver Komsomolets from October 1947 to March 1957 produced: Molotovsky plant Ural, Minsk radio factory, Artel Radiofront, Kaliningrad gorpromkombinat, laboratory Radiofront, Moscow Red October, plant them. Radiofront and several others. The designer of the radio receiver is Mikhail Romanovich Kaplanov, engineer of the Research Institute of the IPCC. The radio "Komsomolets" is designed to receive on the head phones local and powerful not particularly remote broadcasting stations operating in the long to medium wave ranges from 2000 to 250 m. In the receiver coils there is a mobile alsifer core for fusing the receiver. Recommended antenna: outdoor, with a total length of 40-50 m and a suspension height of at least 10 ... 16 m. Antenna wire, suitable for the receiver, is embedded in a single-pole plug inserted into slots A-1, A-2, A-3 , A-4 or A-5, depending on the wavelength of the received radio station. A metal sheet 60x60 cm or more in size, buried to the ground at a depth of 1 m is used as grounding. The grounding wire is embedded in a single-pole plug and this plug must be inserted into slot 3. The head phones are of piezoelectric or electromagnetic type. The plugs from the headphones are inserted into the sockets T. To pre-tune the receiver to the radio station, insert the plug with the antenna wire and the detector into the corresponding sockets of the top panel of the receiver. If the plug with the antenna wire is inserted into the sockets A-1, A-2, then the detector with its plugs must be inserted into the left pair of detector sockets 1 and 2; If the plug with the antenna wire is inserted into the sockets A-3, A-4 or A-5, then the detector must be rearranged into the right pair of detector sockets 2 and 3. The exact tuning to the station is achieved by slowly turning the tuning knob associated with the alsifer core. When this knob is rotated, you can tune in to a radio station operating at approximately the following waves: From 2000 to 1100 m, the spruce plug with antenna wire is inserted in Gneedo A-1, from 1200 to 670 m in A-2, from 800 to 470 m in A-3, from 570 to 340 m in A-4 and from 350 to 250 m in A-5.The recommendation is valid for the antenna described above. In order to receive Moscow radio stations operating at 1724 and 1293 m, the plug with the antenna wire must be inserted into slot A-1 and slowly change the setting until better sound is heard on the head phones of the receiving station. The dimensions of the radio 180x90x42 mm. Unpacked weight 350 g. The receiver was produced in various case designs. Some photographs of the lower cardboard covers indicate the release dates of receivers, such as 1939, 1940, which is not confirmed in the radio engineering literature of those years.
