FM radio receiver on a CD2003GP (TA2003) chip with electronic tuning using varicaps

A simple FM radio receiver on a CD2003 (TA2003) chip. I took the varicaps from a TV tuner from a CRT TV. Instead of varicaps, you can use a variable capacitor, then you need to exclude resistors. Tuning can be done by screwing the brass core into the local oscillator coil
