An automatic frequency control device in which a burst frequency is sampled and held on the output side of an IF amplifier, the held frequency is measured and compared with a preset reference frequency data for obtaining a difference therebetween, and a reference oscillator is controlled so as to keep the difference below a predetermined value, by which the stabilization of an IF frequency and a transmitter carrier wave frequency, both of which are controlled by a reference frequency from said reference oscillator, can be accomplished.
