Radio constructor.
Radio and electrical constructors, sets.Multifunctional devicesThe radio designer has been produced since 1978. On the shelves of stores (1978), another set of parts for novice radio amateurs, `` Radiokonstruktor '', appeared. It was produced by one of the enterprises in Petropavlovsk, Kazakh SSR. The price of the set is 11 rubles. Using its parts, you can assemble 6 different designs. "Radioconstructor" - could be a good help for novice radio amateurs. Unfortunately, however, the manufacturer paid little attention to its products. The instruction is drawn up carelessly, in many diagrams it is almost impossible to make out the denominations of the parts, and a list of typos and clarifications of 30 points is attached to the short explanatory text. Too little attention has been paid to the configuration of the structures, and nothing is said at all about setting up the LF amplifier of the most complex device, although it is known that without selecting the operating modes of its transistors, and sometimes without selecting the transistors of the output stage, the radio amateur will not be able to get comforting results from the amplifier. There are not enough parts in the kit to make all the devices. When assembling a subsequent design, you have to remove parts from the previous one, which can lead to damage to the part. As for the proposed designs, is it worth assembling the same amplifier on different boards three times. It would be easier to assemble one amplifier and connect it to the boards on which a detector receiver or a high-frequency amplifier with a magnetic antenna and a detector stage will be mounted. The editors hope that the manufacturer will eliminate the noted shortcomings and make the kit a really 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 structures. The devices included in the "Radioconstructor" are made on very widespread radio parts, so you can make them from your own parts.
