摘要: A method and apparatus for closed loop frequency control in a two-way radio communication system (100) include base unit (104) portable (108) having portable-to-base initiation channel (202) assigned to predetermined frequency. signal is transmitted (502) from the on an of approximately The determines (506) correction factor (326) recalibrating accordance with communicated (512) (108), recalibrates (516) response.
