Radioconstructor `` Electronics-Kontur-80 ''.
Radio and electrical constructors, sets.Radio receiving devicesSince 1980, the radio designer "Elektronika-Kontur-80" has been producing the Ulyanovsk radio tube plant. The RK is created on the basis of the radio amateur transceiver "Radio-76" and contains assembled boards, units and elements for assembling a radio receiver for receiving amateur radio stations operating in the range 3.6 ... 3.65 MHz (80 m) with a lower sideband (SSB ) and a bandwidth of 3 kHz. Having wound the loop coils, HF transformers and unsoldering them on the boards, and unsoldering the assembled boards according to the instructions given among themselves in the case, then after a simple adjustment of all the boards we get a highly sensitive radio receiver, which, after a little refinement, can be turned into a single-band QRP transceiver or add another radio receiver or two bands, for example 160 meters and / or 40 meters.
