PURPOSE:To improve the operability and to decrease number of components by adopting analog display for the clarification shift quantity of digital display and displaying the analog display together at the lower part of the digital display of operating frequency. CONSTITUTION:The clarification shift quantity of a clarifier frequency DELTAf is advanced by piano touch of a clarifier setting button 30 and in keeping depres sion with a weak pressure, an index spot 28 is circulated on a scale such as scale zero to +5kHz, +5kHz to -5kHz, and -5kHz to zero scale. The restora tion to the scale zero, that is, release of clarify shift is realized by pressing strongly the setting button 30. An index spot button 29 uses piano touch as the information to form transmission side clarification shift and reception side clarification shift, and for the circuit requiring to apply clarification shift both the transmission and reception side at the same time, it is used as identification information that the depression of the spot button 29 has a longer time than the piano touch. In this case, the blink period of the spot button 29 is changed.
