RADIOSOL FM Radio Soldering Kit
This unassembled educational electronics kit teaches basic soldering and electronic assembly through construction of a working FM radio. After correct assembly, the circuit powers on, automatically searches for available FM stations, routes received audio through an amplifier to the speaker, and allows volume adjustment using the onboard potentiometer.
