Abstract

PURPOSE: To make automatic sweep for the station in normal frequency allocation, by presetting the numeral of the auxiliary counter to the sweep counter, in selecting the channel selection from manual sweep of small channel selection step to the automatic sweep of greater channel selection step.
CONSTITUTION: In the PLL synthesizer producing the local oscillating frequency fo, the channel selection operation is made by changing the frequency dividing ratio of the programmable frequency divider 1 by the sweep counter 5. In this case, the auxiliary counter 8 operated parallelly with the sweep counter 5 is provided. At the automatic sweep for greater channel selection step, the counter 8 is changed with the same numeral as the counter 5 and at the manual sweep of smaller channel selection step, the counter 8 is changed while keeping greater step. Further, at the selection from manual to automatic operation, the value of the auxiliary counter 8 is preset to the sweep counter 5. Accordingly, normal channel selection can be made again at the automatic sweep.
