Abstract
This invention is to provide a method for tuning the channel of a broadcasting wave which is able automatically to secure specified band zone and to shorten the time required for tuning. Namely, this method is characterized by starting the PLL tuning by applying the data of the center frequency of either the first channel plan memorized in advance in tuning the channel of broadcasting wave or the second channel plan differing from the allocation of frequencies for said first channel plan, and by judging whether said broadcasting station belongs to either the first channel plan or the second channel plan by applying the tuned frequency at the time that said tuning is finished, and further by renewing said memorized data of the center frequency according to said judged result.
