A portable radio receiver "Signal" in 1964 was experimentally produced by the Kamensk-Uralsky Instrument-Making Plant. ,86e6f450b8cc469628ba70bf2947b049The radio is built on a superheterodyne circuit with seven transistors. ,86e6f450b8cc469628ba70bf2947b049In terms of the scheme, it is similar to the Neiva and Jupiter receivers, differing in design, built-in clock, which, in addition to the clock function, allow you to automatically turn on the receiver at a specified time. ,86e6f450b8cc469628ba70bf2947b049The receiver has both LW and MW wave ranges. ,86e6f450b8cc469628ba70bf2947b049Sensitivity in the LW range - 1.5 mV / m, SV - 0.8 mV / m. ,86e6f450b8cc469628ba70bf2947b049Selectivity on the adjacent channel at 10 kHz detuning in the LW ranges - 24 dB, MW - 20 dB, specular - 30 dB. ,86e6f450b8cc469628ba70bf2947b049When the signal at the input changes 20 times due to AGC, the voltage at the ULF input changes 2 times. ,86e6f450b8cc469628ba70bf2947b049Power is supplied from the Krona battery. ,86e6f450b8cc469628ba70bf2947b049Loudspeaker 0.1GD-12. ,86e6f450b8cc469628ba70bf2947b049You can connect a TM-4 telephone to the receiver, and the loudspeaker is turned off. ,86e6f450b8cc469628ba70bf2947b049There is a jack for an external antenna. ,86e6f450b8cc469628ba70bf2947b049The rated output power of 60 mW is maintained when the supply is reduced to 7.2 V. The quiescent current is 4 mA. ,86e6f450b8cc469628ba70bf2947b049The dimensions of the receiver are 121 x 77 x 36 mm. ,86e6f450b8cc469628ba70bf2947b049Weight - 400 gr. ,86e6f450b8cc469628ba70bf2947b049Includes leather case. ,86e6f450b8cc469628ba70bf2947b049The price of the radio is 36 rubles 83 kopecks.,86e6f450b8cc469628ba70bf2947b049,null,ru,null,null,null,null
