PURPOSE:To rationalize the interface between an operation panel and a print board and improve the operability by providing the first, the second - the n-th pulse integrating counters and a push-button which sends a desired number of integral pulses to pulse integrating counters and controlling a transmitting/receiving circuit on a basis of integral values. CONSTITUTION:When the initial value of a pulse integrating counter Q1 is not changed, the integral value is the least significant bit LSB, and a channel ch1 is selected, and its frequency data and radio wave mode data are displayed on a display device 2. A frequency adjusting dial 3, a frequency adjusting up button 4, and a frequency adjusting down button 5 are operated to determine a transmission/reception frequency. The function of a pulse integrating counter Q2 is in the operation mode and the LSB is in the SSB.L side, that is, the radio wave mode is SSB and a lower side-band is set; and therefore, if on/off switches 12 and 13 for transmission/reception switching or VOX are operated when it coincides with desired transmission and reception waves, transmission and reception are possible immediately. If the initial value of the pulse integrating counter Q2 is set to 5 corresponding to FM, the radio wave mode is FM when power is turned on. |
