DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 (1), (2), (3) and (4), the present invention provides a spectrum display section provided in a part of the display section.
In this case, FIG.
(For example, HF / VHF, HF / UH as a combination when there are two or more different frequency bands)
F, HF / SHF, VHF / UHF, VHF / SHF,
UHF / SHF, HF / VHF / UHF, UHF / VH
F / SHF and the like can be considered. FIG. 1 (1) shows a state in which the signal level of the currently received signal is displayed in a dot matrix system using the audio band display screen on the right display surface when viewed from the front. . On the upper side, the currently received frequency is displayed by a number, and when viewed from the front, the value of the currently used frequency is displayed on the left display surface, and on the lower side, a square L by the segment system is displayed.
Although the signal strength is displayed by providing a row of CDs, the display surface here may also be used as a spectrum display unit and various other displays may be performed, and three or four frequency bands are used.
As the number increases, the number of variations in the various display units increases. For example, if the number of used frequency bands is three, the number of spectrum display units can be selected and used from one to three. Further, the position may be arranged at any position on the left, right, or middle side. In addition, the arrangement of the display units is not limited to being arranged horizontally, but may be arranged vertically or diagonally, and the display by the segment method may use the display surface of the dot matrix method. FIG. 1C shows a case where three frequency bands are used.

FIG. 1B shows a part of the display unit.
This is the screen that was displayed. This shows the frequency value of the signal currently being received on the display surface on the right side viewed from the front and the level of the signal in the segment system, and the graph is scanned. The minimum value and the maximum value of the frequency are displayed, and the display surface on the left side when viewed from the front is of the segment type in the figure, but this display surface is also the spectrum display unit, and other various displays are displayed. As the number of used frequency bands increases to three, four, etc., the variations of various display units increase. For example, if the number of used frequency bands is n, For example, the number of the spectrum display units can be selectively used up to n, and the position of the arrangement can be variously changed. Further, the arrangement of the display units is not limited to being arranged horizontally, but may be arranged vertically or diagonally. FIG. 1D shows a case where the number of used frequencies is n.

FIG. 2 is a block diagram showing an outline of the present invention (the one shown in FIG. 2 has two receiving units and two types of operating waves). Receiving, and each received wave to a high frequency amplifier (RF) 2,
2 ', signals from phase-locked loops (PLLs) 5, 5' controlled by CPU 8 and voltage controlled oscillators (VCOs) 4, 4 'inputting outputs of PLLs 5, 5'.
And the signals from the high frequency amplifiers (RF) 2, 2 'are mixed by mixers 3, 3', and the intermediate frequency amplifiers (IF) 6, 6 '
To enter. Thereafter, the signals are inputted to detectors (DET) 7, 7 '. Since the radio of the present invention is of a dual-watch type, signals of two different frequency bands are inputted, and a speaker 14 is inputted.
Therefore, the detected signal is input to the interface circuit 12 once, connected to the low-frequency amplifier (AF) 13, and the sound is output from the speaker 14.

In the present invention, data such as the signal level and carrier of the received signal are taken into the CPU 8 from the two intermediate frequency amplifiers (IF) 6, 6 ' and stored in the memory 9.
Then, the CPU receives the received signal and the audio band data.
Segment system or the LCD display 11 reads out over data is displayed in a dot matrix manner. FIG.
(1) voice band spectrum Display of the peripheral in Figure 1 (2)
Selection switch 1 for selecting whether to display the spectrum of the wavenumber band
0 is provided on the radio panel etc. and the selection switch is turned off.
In other words, the control signal from the CPU 8 is output and the audio band is
The display of the spectrum and the frequency spectrum change. Also,
A frequency that can be used without detecting the reception level in the reception frequency band
The wave number is also stored in the memory 9.

The operation of the CPU 8 when displaying the level of the reception frequency on the LCD display 11 will be described with reference to the block diagram of FIG. 2 and FIG. FIG. 3 shows the scanning operation.
In the description, (from step 1 to step 9) indicates a processing procedure number.

First , the spectrum analyzer function is set to O.
N (step 1), frequency band for flag scanning
It is set to the lower limit frequency of the band (step 2). (The numerical value of the frequency can be freely set by software.) Thereafter, scanning is started (step 3), and it is determined whether or not there is a carrier to be received (step 4).

If a carrier is detected, the signal level and frequency in use are stored in the memory 9 (step 5). Thereafter, the contents are displayed on the LCD display 11 (step 6). If no carrier is detected, the flag is raised by one step to start scanning the next frequency (step 7). At LC
Similarly, after displaying on the D display 11, the flag is raised by one step to advance the frequency scanning to the next stage (step 7). When the upper limit flag is reached (step 8), the detection is terminated (step 8). 9) If the upper limit flag has not been reached yet, return to step 4 and repeat carrier detection.

[0016]

The present invention has a new function of displaying the audio band of the reception frequency and displaying the signal strength of each frequency by the segment system or the dot matrix system. Measures the intensity, stores the measurement results in memory, and stores the available frequencies in order, so that the frequency in use can be called immediately, and displays whether the frequency is an empty channel or busy. There is.

Further, according to the present invention, in addition to the above-mentioned effects, the waveform of the modulation can be seen in a graph. In addition, various displays other than those shown in the embodiment are possible.
The display of PS will be possible in the future.
