Radioconstructor `` Fon-6 ''.
Radio and electrical constructors, sets.Radio receiving devicesSince 1989, the radio designer "Fon-6" has been producing the Moscow plant "Elling". The Fon-6 set is a complete HF and IF VHF-FM radio receiver in the 65.8 ... 74 MHz range, providing a noise-limited sensitivity of 5 μV at a signal-to-noise ratio of 26 dB. Single-signal selectivity for the mirror channel is 32 dB, for the IF 42 dB. The radio path is assembled on a KT368AM transistor (URCH) and a K174PS1 microcircuit (heterodyne and mixer). The K174XA6 microcircuit performs the functions of an IF amplifier and a detector. It is preceded by an IF amplifier based on 2 KT368AM transistors. The use of the K174XA6 microcircuit ensures the operation of the AFC (electronic frequency tuning in the URCH and the local oscillator), silent tuning to the radio station. The supply voltage of the unit is 15 V. The consumed current is about 30 mA. Using the set together with the sets "Fon-7", "Fon-8", "Fon-9", Fon-10 and "Fon-11" you can assemble a high-quality stereo VHF-FM receiver.
