摘要： PURPOSE:To simultaneously observe the signal intensities of plural frequencies by displaying the signal intensity of the plural frequencies, automatically changing a received frequency, and shifting and changing the display position of the signal intensities of the plural frequencies corresponding to it. CONSTITUTION:An IF signal outputted from an IF amplifier 6 is detected by a detection circuit 19, and A/D converted, and the converted data are fetched in an MPU 30 as signal level data SLD. Next, at the time of a receiving state on a search mode, while the oscillation frequency of a local oscillator 4 is changed, and level display data corresponding to the signal level data are written in a VRAM 40. Then, the signal level of the low frequency to be modulated of the high frequency signal of the received frequency is displayed on a matrix display part 61 of an LCD 60. Also, a scan search mode is set, the frequency is automatically changed at every step frequency, and the signal level data in the VRAM 40 are shifted. Thus, the signal intensity of the plural frequencies can be simultaneously observed.

摘要： PURPOSE:To simplify the circuit configuration and to reduce the manufacture cost by using one system of reception circuit used in common to display signal intensity of plural frequencies. CONSTITUTION:After an IF signal outputted from an IF amplifier 6 is detected by a detection circuit 19, an A/D converter 20 converts the signal into digital data being signal level data SLD, which are received by an MPU 30. In the case of the search mode and in the reception state, The signal level data SLD are received while a local oscillating frequency fL from a local oscillator 4 is sequentially changed and level display data corresponding to the data are written in a VRAM 40. While a low frequency signal of a modulated wave of a high transmission reception frequency fR is outputted from a speaker 13, signal levels of plural frequencies are displayed around a signal level of the transmission reception frequency fR on a matrix display section 61 of an LCD 60. Thus, the signal strength of plural received frequencies is respectively displayed respectively corresponding to the switching sequence.

摘要： PURPOSE:To simultaneously observe the signal intensity of plural frequencies, and to easily discover an empty channel by displaying the signal intensity of the plural frequencies, and shifting and changing the display position of the signal intensity corresponding to the change of a received frequency. CONSTITUTION:A received high frequency signal is inputted through both a changeover switch 10 and an RF amplifier 2 to a mixer 3, mixed with the signal of a local oscillator 4, and converted into an IF signal. The IF signal outputted from an IF amplifier 6 is detected by a detection circuit 19, A/D converted. and stored in an MPU 30 as signal level data SLD. Then, at the time of a receiving state on a search mode, while the frequency of the oscillator 4 is changed, level display data corresponding to the signal level data are written in a VRAM 40, and the low frequency signal of a wave to be modulated of the high frequency signal is displayed on an LCD 60 in order of the signal level. Also, the display position of the signal level can be shifted and changed corresponding to the change of the received frequency. Thus, the signal intensity can be simultaneously observed.

摘要： PURPOSE:To easily observe the signal strength and working status of a channel by displaying the signal strength of plural frequencies in a prescribed order such as an order of stored channel number, etc., and shifting a display position corresponding to the change of a reception frequency. CONSTITUTION:When a scan search mode is set in a memory channel mode, the display position of a signal level at the matrix liquid crystal display part 61 of an LCD 60 is displayed by successively shifting the display position in the ascending or descending order of a memory channel number by repeating the automatic change of a transmission/reception frequency in a direction of ascending or descending order of the memory channel number according to the transmission/reception frequency stored in memory in an MPU 30 in advance corresponding to the memory channel number until the scan search mode is cancelled, and shifting data of signal levels of reception signals of plural frequencies stored in a VRAM 40. Also, the setting of the channel number is performed by turning a rotary encoder 31 in a rightward or leftward direction after turning on an ordinary mode/scan search mode change-over switch SW5.

摘要： PURPOSE:To easily observe the signal strength and working status of a channel by displaying the signal strength of plural reception frequencies centering about a prescribed center frequency corresponding to a switching order, and shifting a display position corresponding to change. CONSTITUTION:A detection circuit 19 detects an IF signal from an IF amplifier 6, and an A/D converter 20 converts it to signal level data(SLD), and makes an MPU 30 that is a control circuit fetch it. Thence, the MPU 30 writes level display data in accordance with the data SLD on a VRAM 40 as changing the frequency of a local oscillator 4 sequentially when a reception state in a search mode is set. Thus, a frequency demodulator 8 demodulates a signal of transmission/reception frequency(fR), and a speaker 13 outputs a sound, and the liquid crystal display part 61 of an LCD 60 displays the signal levels of seven frequencies centering about the frequency (fR). Also. the change of the frequency (fR) in a high or low direction is automatically repeated at every step by performing mode setting, and the display position is also shifted corresponding to that. In this way, the signal strength and the working status of the channel can easily be observed.
