Design and construction of an FM receiver signal booster

Abstract

This research report was made to design and construct an FM receiver signal booster to connect to an FM receiver antenna to boost FM reception. The FM receiver signal booster was constructed using C547B P H01 transistor, 470µ H inductor, 1 MΩ resistor, two 104 K capacitors and an antenna. Connecting the circuit on the FM receiver antenna and tuning to the unclear radio signal, the radio signal became clear. The signal that was originally full of noise that it could hardly be heard became very clear and loud. This result was in good correlation to the ones obtained using a CRO where the frequencies between 100 KHz and 180 kHz.
