Radio and electrical constructors, sets.Receiving and transmitting devicesSince the 1st quarter of 1992, the Yana radio amateur set-designer has been producing the Scientific and Production Commercial Enterprise "SAAS". The radio constructor is intended for assembling a set of two small-sized simplex radio stations. The assembly is available even to a novice radio amateur. To successfully conduct it at home, you need an oscilloscope and a universal measuring device (avometer). The frequencies of the transmitter and the local oscillator of the radio receiver are stabilized by quartz resonators. RS technical characteristics: transmitter frequency 27.14 MHz; output power 10 mW; amplitude modulation. The receiving path is a superheterodyne, an intermediate frequency of 565 kHz. The sensitivity of the radio receiver at a signal-to-noise ratio of 10 dB is not worse than 3 μV. Supply voltage 9 V. Antenna - telescopic, 650 mm long. The mass of one radio station is 245 gr. Working temperature from +15 to +40 ° С. The range in the city is not less than 700 m, above the water surface - not less than 2.5 km. Registration and permission to operate the radio station is not required. The price of a radio designer set is 1300 rubles (for 1992). The enterprise also supplied ready-made radio stations.
