What condition may prevent a VHF radio receiver from staying tuned to the desired channel?
The local oscillator frequency is beating against the incoming signal to produce an Intermediate Frequency (IF).
The output signal of the Phase Locked Loop ( PLL ) circuit in the frequency synthesizer has become unlocked .
The discriminator circuit is alternately developing positive and negative voltages at the modulation frequency.
The ratio detector circuit is producing a variable output that deviates across the receiver's dynamic range.
