Frequency-modulated 52 MHz oscillator. The circuit uses an MPS6511 transistor especially designed for oscillators. The 1N5146 is a varactor diode rated at 33 pF for are verse bias of -4volts. L2 and L3 are used to tune out unwanted harmonics. Audio inputs should be limited to 200 mV or less (courtesy Motorola Semiconductor Products, Inc.).
