AMATEUR RADIO COMMUNICATION EQUIPMENT

摘要

PURPOSE:To bring automatically an idle channel into a talking channel by providing the 1st and 2nd storage means storing respectively a oscillation frequency data at call and a frequency data and a group code storage means and generating an output data corresponding to a storage group code and a storage frequency data of the 2nd storage means. CONSTITUTION:An oscillation frequency of a frequency syntherizer 5 is set by a stroge frequency data of a storage means 22 or 20 applied via a selection means 21. A group code in the received input data is compared with the stored group code at a group code comparison means 24 and when the coincidence between both the group codes is detected, the frequency data in the input data of the reception signal is selected and fed to the storage means 20. A selection means 21 selects a storage frequency data of the storage means 20 and the frequency synthesizer 5 is set to a frequency corresponding to a frequency data in the input data of the reception signal. Thus, the amateur radio communication equipment is locked automatically to the idle channel.
