Fm Crystal Radio Schematic

This units selectivity is far better than you would expect to find in a crystal receiver and volume is. The circuit is actually pretty simple, just two variable capacitors (c1 & c2), a coil (l) with 8 taps and a tap. The fm radio signal is picked up by the antenna, which as we. Surprisingly, the coil has a relatively high q, which increases selectivity and allows the radio to tune in five local stations when connected to a 100 foot.
