The radio "Malchish" (the first option) from the radio designer since 1973 produced the Experimental-experimental school plant "The Seagull".
RK is a set of radio components, components and housing for assembling a pocket radio receiver of direct amplification on germanium transistors operating in the DV range.
The radio designer is intended for beginner amateur radio enthusiasts who have an initial knowledge of radio engineering.
From the beginning of production, the receiver board was made of PCB, there was no window for the dial of the tuning dial in the receiver case (however, not for long), the KPI had no stops and rotated around.
There were inconsistencies in the electrical and wiring diagrams of the receiver.
Because of this, there were complaints about the set, and many novice radio amateurs could not get the assembled receiver to work.
In the fall of 1975, all the flaws were eliminated, and the receiver board began to be made of pressed cardboard.
After that, the number of assembly claims has declined sharply.
In this form, the upgraded radio designer was produced until the spring of 1989.
