Radio constructor has been produced since 1978. On the shelves of stores (1978), there was another set of parts for beginner radio amateurs '' Radio designer ''. It was produced by one of the enterprises of the city of Petropavlovsk, the Kazakh SSR. Price set 11 rubles. Using its parts, you can assemble 6 different designs. '' Radio constructor '' could be a good help for novice radio amateurs. Unfortunately, however, the manufacturer has shown little attention to their products. The instruction is drawn up carelessly, it is almost impossible to disassemble the details of the parts in many diagrams, and a list of misprints and updates of 30 points is attached to the short explanatory text. Too little attention is paid to tuning the structures, and nothing is said about setting up the low-frequency amplifier of the most complex device, although it is known that the amateur will not be able to get comforting results from the amplifier without selecting the output stage transistors. There are not enough details in the kit for manufacturing all devices. When assembling a subsequent structure, it is necessary to remove parts from the previous one, which may lead to damage to the part. As for the proposed constructions, is it worth it to assemble the same amplifier on different boards three times? It would be simpler to assemble one amplifier and connect it to the boards on which the detector receiver or high-frequency amplifier with a magnetic antenna and a detector cascade will be mounted. The editors hope that the manufacturer will eliminate the noted shortcomings and make the set a truly practical tool for radio circles, as well as self-employed radio amateurs. The published article aims to help radio amateurs who bought this set to assemble and adjust the structure. Devices included in "Radioconstructor" are made on very widespread radio components, so you can make them from your parts.
