Chapter 9: FM Receivers
n0gsg.comadvent of frequency synthesizers, the frequency of the local oscillators in FM receivers was controlled by discrete LC resonant “tank” circuits, just like in an AM receiver. Using an LC tank allows the oscillator to drift off frequency and as luck would have it, drift becomes much more difficult to control in a VHF oscillator.
