摘要： PROBLEM TO BE SOLVED: To provide radio communication equipment with a scanning function capable of automatically setting a required one as a preferential channel on the basis of the condition that call termination signals are actually detected in scanning reception in the past, and its control method. SOLUTION: The number of times of call termination and the call termination time for respective reception channels are counted within prescribed time or during the prescribed number of times of scanning cycles, a reception history is referred to, a priority degree is evaluated, and the preferential channel is automatically set.

摘要： PROBLEM TO BE SOLVED: To prevent the malfunction of a receiver by shifting a local oscillation frequency for a seven-channel tuning selection from a normal frequency in a search tuning operation or auto preset operation mode of a television broadcasting wave and eliminating a VHF eight-channel video carrier at a sound trap for a receiving channel of an intermediate frequency filter. SOLUTION: In this method, the local oscillation frequency of a tuner in a seven-channel receiving mode is set lower by 0.5 MHz and the influence of an eight-channel video carrier is eliminated according to the software correspondence of a turning microcomputer in an auto preset operation mode and in an auto search operation mode. When the frequency L7' obtained by lowering a normal oscillation frequency L7 by 0.5 MHz is used for a local oscillation frequency in the seven-channel receiving mode, an intermediate frequency to the eight-channel video frequency becomes 54.25 MHz and falls into a sound trap of a SAW filter. As a result, receiving sensitivity can further be lowered as much as trap attenuation quantity.

摘要： PROBLEM TO BE SOLVED: To obtain a receiver which has fast tuning function at a low cost by operating the difference between the frequency value of a measured intermediate frequency and the frequency value of a prescribed intermediate frequency, performing additive correction of the difference to a tuning frequency and retuning. SOLUTION: An IF counting part 6b of a microcomputer part 6A measures an intermediate frequency, that is a difference between a local sending frequency which corresponds to a tuning frequency and an antenna-receiving frequency which is inputted via an IF detecting part 3. Next, a calculating part 6c operates the difference between a measured value and 450 kHz complete tuning frequency. The tuning frequency is reset by adding a frequency difference to a scan frequency, i.e., a tuning frequency that is generated by a tuning frequency setting part 6d. A PLL part 8 scans a tuning frequency which is set by the part 6d, i.e., a receiving wave for each frequency value, that adds a scan frequency which gets a value for each frequency of a prescribed interval to a prescribed intermediate frequency. With this, a receiver completely tunes in with respect to any antenna input frequency.
