Abstract
A voltage variable capacitor tuned radio receiver having a circuit which delays operation of a portion of the radio receiver circuit which includes the automatic frequency control circuit after the radio receiver is first energized until the filter capacitor at the output of the tuning voltage generator has charged to a selected tuning voltage to prevent the automatic frequency control circuit from locking the radio receiver onto an undesired RF carrier frequency.
