The frequency data of the empty channel found by the empty channel searching means 17 is supplied to the selecting means 25, and when an empty channel is detected, the selecting means 25 is supplied with the frequency data of the empty channel outputted from the empty channel searching means 17. On the selection side, the transmission/reception switching means 6 is switched from the reception side to the transmission side and the modulation signal switching means 10 is switched from the audio signal amplifier 8 side to the output side of the output data generation means 9 for a predetermined period, and when this predetermined period has elapsed, the selection is made. The means 21 is configured to supply frequency data stored in the storage means 20 to the frequency synthesizer #f5 in place of frequency data stored in the storage means 22 described later. The output of the selection means 25 is also supplied to the storage means 20.

The automatic channel selection device 15 further includes a group code storage means 23, a call sign code storage means 26, a stored frequency data in the storage means 20, a stored group code in the group code storage means 23, and a stored call sign in the call sign code storage means 26. output data generation means 9 for generating corresponding output data by assigning a code to the output data; a storage means 22 for storing frequency data corresponding to the oscillation frequency at the time of calling; It is equipped with a group code comparison means 24 for detecting a match between the code and the group code stored in the group code storage means 23, and a call sign display means 27 for decoding the call sign code in the input data and displaying the call sign. The frequency data in the data is supplied to the selection means 25. Based on the coincidence detection output of the group code comparison means 24, the selection means 25 switches to select frequency data in the input data and supply it to the storage means 2o.

(Operation of the Invention) Amateur radio communication of the present invention configured as described above.
In this case, the storage means 22 stores frequency data corresponding to the oscillation frequency at the time of the call, which has been arranged in advance with the communication partner, the group code storage means 23 stores the group code agreed upon with the communication partner in advance, and the call sign code is stored. The means 26 stores a call sign code corresponding to the call sign.

Further, the oscillation frequency of the frequency synthesizer 5 is determined by the selection means 21.
It is set by the storage frequency data of the storage means 22 or 20 supplied via the storage means 22 or 20. That is, the frequency division ratio of the variable frequency divider of the frequency synthesizer 5 is set according to the stored frequency data of the storage means 22F or 20 supplied via the selection means 21.

On the other hand, the transmission/reception switching means 6 is normally switched to the reception side, and receives radio waves at a set reception frequency determined by the oscillation frequency of the frequency synthesizer 5.

When the call instruction means 16 issues a call instruction, the empty channel search means 17 which receives the call instruction signal searches for an empty channel. When an empty channel is found by the empty channel search means 17, the frequency data of the empty channel is stored in the storage means 20 via the selection means 25.

On the other hand, the group code stored in the group code storage means 23, the call sign code stored in the call sign code storage means 26, and the frequency data stored in the storage means 2o transferred to the storage means 20 as described above are The data is stored in the output data generation means 9, and subjected to predetermined data processing to generate output data.

On the other hand, the empty channel search means 17
When the f channel is detected, an output is generated to the modulation signal switching means 10 and the transmission/reception switching means 6 at least until the end of transmitting the output data. The modulated signal switching means 10 receiving this output is switched from the output selection side of the audio signal amplifier 8 to the output selection side of the output data generation means 9, and the transmission/reception switching means 6 is switched from the reception side to the transmission side. Further, the selection means 21 selects the frequency data stored in the storage means 22 and applies the selected data to the frequency synthesizer 5.

The modulated signal supplied to the transmitter 2 is the output data generated by the output data generation means 9, and the frequency data in the output data is the frequency data stored in the storage means 20, that is, the frequency data of the empty channel. . The carrier frequency of the modulated wave transmitted from the transmitter 2 is stored in the storage means 2.
This is the frequency corresponding to the storage frequency data of No. 2, and this carrier wave is modulated by the output data and transmitted.

When the transmission of the output data is completed after a predetermined period of time has elapsed, the empty channel search means 17 outputs a switching signal for switching the selection means 21, and also outputs the signal outputted to the transmission/reception switching means 6 and the modulation signal switching means 10. Extinguish.

Therefore, the selection means 21 selects the frequency data stored in the storage means 20 instead of the frequency data stored in the storage means 22 and supplies it to the frequency synthesizer 5. Further, the modulation signal switching means 10 is switched to the output side of the audio signal amplifier 8, and the transmission/reception switching means 6 is switched to the receiving side. As a result, the frequency synthesizer 5 is set to a frequency corresponding to the frequency data of the empty channel, and the amateur radio communication device enters a state of waiting for radio waves of the frequency of the empty channel to be transmitted.

Next, the operation of receiving a call from another amateur radio communication device and being drawn into a designated empty channel will be explained.

The call sign code in the received input data is decoded by the call sign display means 27 and the call sign is displayed.

The group code in the received input data is determined by the group code comparison means 2.
At step 4, the stored group code is compared with the stored group code stored in the group code storage means 23, and a match is detected. When a match between both group codes is detected, the selection means 25 is switched by the output of the group code comparison means 24, and the frequency data in the input data of the received signal is selected and supplied to the storage means 20.

At this time, the selection means 21 selects the frequency data stored in the storage means 20, and the frequency synthesizer 5 is set to a frequency corresponding to the frequency data in the input data of the received signal. As a result, the amateur radio communication device is automatically drawn into an empty channel.

Therefore, by pressing the PTT switch 14, the transmission/reception switching means 6 is switched to the sending side and transmission is performed, and by stopping the pressing of the PTT switch 14, the transmission/reception switching means 6 is switched to the receiving side. , communication will be performed on the frequency of the above-mentioned empty channel.

Note that FIG. 3 further shows the block diagram shown in FIG. 2 as a functional block diagram.

Hereinafter, the operation of one embodiment of the present invention will be explained with reference to the flowcharts shown in FIGS. 4 to 6 as well as FIG. 3. 〒First,
When the amateur radio communication device of the present invention is operated, it enters a receiving state unless a special operation is performed.

When the program is started, the code selection means 101 detects whether setting a call sign code has been selected (step ar). The code selection means 101 can specify setting of a call sign code and setting codes A and B. As will be described later, when a call sign code setting instruction is given, a signal from the microcomputer 80 is used to set setting 1 to code A. It is configured so that the shape can be controlled. Furthermore, the setting codes A and B are referred to as setting codes in order to function as so-called group codes as well as hood squelch codes, but hereinafter they will be referred to as group codes A and B.

In addition, the call sign code etc. can be set using code setting means 1.
Set by 02. For this reason, for example, one character of the ASCII code is specified by pressing the code setting means 102 four times, and the code setting means 10 pressed the first two times.
The hexadecimal number corresponding to the upper 3 bits of the 7-unit ASCII code is obtained by adding the value indicated by 2, and the lower 4 bits of the 7-unit ASCII code are obtained by adding the value indicated by the code setting means 102 pressed the next two times. The hexadecimal numbers corresponding to are shown respectively.

When setting a call sign code is selected in the switch a1, a second count area (hereinafter referred to as a counter) is provided in the RAM 83 to set the number of digits of the call sign. 104
is cleared (step a2), and then the first counter 103 provided in the RAM 83 is cleared in order to count the number of times the code setting means 102 is pressed so that it corresponds to one character of the American code (step a2). step a
a). Next, the key switch output supplied from the code setting means 102 is loaded into the call sign code calculation means 106 which adds the values pressed twice to convert it into an ASCII code (step a4), and then the first The counter of ii +1 j+ is incremented (step a
s＞. Steps a4 to a5 are repeated a number of times corresponding to one ASCII code character (step aS). The input code is then converted to ASCII code (step a7),
The converted ASCII code is stored in the call sign code storage area 107 provided in the RAM 83, and the stored contents are displayed on the call sign display 114 via the code selection means 113 (step aS). Next, the second counter 04 is incremented by 1" (step aS), and steps a3 to a9 are repeated a number of times corresponding to the digit of the call sign (step are). In step alo, the count value of the second counter 104 reaches the digit of the call sign. When the value corresponds to the number of digits, call sign code storage area 10
7, the call sign code is completely stored, and a flag is set in the call sign code setting state storage area 108 provided in the RAM 83 (step a!
1). Next, the call sign code selection of the code selection means 101 is canceled and the position where group code A is to be set is selected (step a12).

Following step a12, it is detected in the code selection means 101 whether setting a group code has been selected (step a13).

In this example, the group hood is group code (A).

Although the example shown in (B) is a case where two group codes can be set, it is not necessary to limit the setting to two group codes.

When selecting a call sign code is not selected in step a1, step a13 is executed following step a1.

In step a13, if setting the group code is selected, the 30th counter 105 provided in the RAM 83 and counting the number of digits of the group code is cleared (
Step a14), the selected group code is the group code (A
) is detected (step aXS). When it is detected in step a15 that the group code (A) is selected, the input code is loaded into the first group code storage area 109 provided in the RAM 83 (step asse, the third counter 105 but ,
The set group code (A) is displayed on the data display 1S112 via the data display selection means 111 (step aIS). Following step ale, steps a15 to aL11 are performed until the count value of the 30th counter 105 reaches the number of digits of the group code.
is repeated, and when the count value of the third counter 105 reaches the number of digits of the group code (step aS9), step a13 is executed next. Therefore, the group code (A) set in the first group code storage area 109 is stored.

When the group code selected in step a15 is not group code (A), it is group code (B), and in this case, following step als, steps atS to atS
Steps 820-823 similar to are performed. As a result, the group code (B) set in the second group code storage area 110 provided in the RAM 83 is stored.

In step all, it is detected whether the group code selection means 115 has selected a sword for which group code setting is not selected to have a group code (A) and use it for receiver U (step a24). . When the group code (A) is selected by the group code selection means 115, it is detected whether the group code (A) is stored in the first group code storage area 109 (step a25).

In step a25, the first group code storage area 10
When the group code (A) is stored in RAM 8,
Group code (A) selection permission storage area 1 provided in 3
16 (step a26), and the set group code (A) is displayed on the data display 112 together with a specific display such as a decimal point (step a27).

Next, it is detected whether the group code (B) is selected for use by the group code selection means 115 (test tube a28).

If the group code (A) is not selected in step a24, or if the group code (A) is not set in step a2S, step a24. Step a28 is executed following a2s.

When the group code (B) is selected in step a28, the group code (B) is the second
It is detected whether the code is stored in the group code storage area 110 (step a29).

In step 82B, the second group code storage area 11
When the group code (B) is stored in 0, RAM83
Snoring code (B) selection permission storage area 11 provided inside
7 is set (step a3o), and the set group code (B) is displayed on the data display 112 along with a specific display such as a decimal point (step a: +t). It will also be clear from steps 824-a30 that both group codes (A> and (B)) may be selected.

Following step aSS, a calling routine is executed.

Also, when the group code (B) is not selected in step a211, step a is selected.
Following steps 2j and 82G, a calling routine is executed.

As is clear from the above, the call sign code and group codes (A) and (B) can be set. Also, group code (A)
, (B) is set and stored, step a24
．． If it is not selected in a211, the carrier is not used for any purpose.

Next, the calling routine will be explained with reference to FIG.

In the calling routine, it is detected whether the system operating state setting means 118, which specifies whether to automatically connect the communication device to the other party's communication device, is set (step b).
s). If the system operating state setting means 118 is not set in step b1, the calling routine is skipped and a transmitting/receiving routine to be described later is executed. step b1
When the system operating state setting means 118 is set in step b1, it is detected whether the call setting means 119 is set (step b2). In step b2, call setting means 1119
If not set, the sending/receiving routine is executed, skipping the calling routine. When the call setting means 119 is set in step b2, it is detected whether a call sign is set following step b2 (step El).

Whether a call sign is set is detected by whether a flag is set in the call sign code setting state storage area 108. If the call sign is not set in step b3, the calling routine is skipped and the transmitting/receiving routine is executed.

Therefore, if a call sign is not set, the call will not be made and the call will not be linked to the other party.

When the call sign is set in step b3, following step b3, the mute means 120 is set to an operating state, that is, a mute-on state (step b4). Since muting is applied in step b4, when searching for a free line, the system enters an i-communication state, but the audio is muted. Following step bi+, it is detected whether am is connected (step bs
).

Detection of whether or not one wire is connected is performed by checking whether a flag is set in the line connection storage area 121 provided in the RAM 83. When the line is connected in step bs, the system enters a re-calling state, which will be described later.
There may be cases where the condition is reached by repeating the rotation.

When the line is not connected in step b5, the frequency data stored in the frequency data storage area 122 provided in the RAM 83 is stored in the RAM 83.
Start channel data storage area (
(hereinafter referred to as S channel data storage area) 123 (step be). In addition, here, in the frequency data storage area 122, before step b6,
Frequency data negotiated with the communicating party is set by a frequency data setting means 124 consisting of a rotary encoder or the like, and this setting data is stored in a frequency data storage area 122.

Continuing from step b6, the holding state is prohibited (step b7). The standby mode is disabled by resetting the flag in the standby state storage area 125 provided in the RAM 83. Following step b7, the empty channel lead indicator 126 is lit to indicate that empty channel leading is in progress (step be). Note that empty channels may be displayed by an audio display (for example, a beep sound) in addition to the light display.

In addition, priority selection state setting means 1 for preferentially selecting frequency data, for example, fx, 'f2, which are preset separately in the CH data storage area 127 and the f2 data storage area 128 provided in the RAM 83, as a communication channel.
It is detected whether 29 is set (step b9)
. When the priority selection state is set in step b9, the frequency data f1 is stored in the frequency data storage area 1.
22 (step b1o), the first timer 30 starts timing (step bll), where the frequency synthesizer 5 is loaded into the frequency data storage area 122.
The tree exit frequency is set based on the frequency data stored in . Therefore, the receiving frequency (when receiving) and the double frequency (when transmitting) are set. Following step bll, the comparator 39 outputs a telegraph signal of one wave number corresponding to the 11 frequency data loaded into the 1 frequency data storage area 122 if it is below a predetermined level.

It is detected by the empty range detection means 132 (step b12), and it is detected whether the received falcon signal level continues to be below a predetermined level for the set time of the first timer 130 (step b1a). In step b13, if the received signal level in step b12 continues to be below the predetermined level during the setting of the first timer 130, it is determined that the frequency corresponding to the 11 frequency data is an idle line, and the step described below is performed. Execute b27.

Further, if the received signal level exceeds the predetermined level in step b12, or if the received signal level is below the predetermined level in step b13 and does not continue for the set time of the first timer 130, then in step b12, the frequency Data f2 is loaded into the frequency data storage area 122 (Stella 7b1+), and the first
The timer 130 starts counting (step tls).
. Following step b15, frequency data storage area 5
It is detected whether the received signal of the frequency corresponding to the 12 frequency data loaded in the 122 is below a predetermined level (step b16), and the received signal level remains at the predetermined level or above for the set time of the first timer 130. It is detected whether the user is doing so (step b17). In step b17, it is determined that the reception signal level in step b16 has been below the predetermined level for the set time of the first timer, and Stellar b2'/, which will be described later, is executed. Also, whether the received signal level exceeds a predetermined level in step b, t6, or step b17. The first condition is that the received signal level is below a predetermined level.
If the set time of the timer 130 does not continue, in step blH, the frequency data generated by the random frequency generating means 133 is loaded into the frequency data storage area 122 (step bxs), and then the frequency data is stored in the frequency data storage area 122. The frequency data is increased (step b19).

When the priority selection state setting means 129 is not set in step b9, step b18 is executed subsequent to step b9. In this case, no selection is made as to which frequency data should be prioritized.

Following step blB, frequency data such as i3. It is detected whether the selection exclusion state setting means 134 for excluding selection of J4 as a communication channel is set (step b2o). step b
When the selection exclusion state is set in step 20,
The frequency data comparing means 138 detects whether the frequency data stored in the frequency data storage area 122 matches the frequency data f3 (step b2).
I). In step b21, the frequency data stored in the frequency data storage area 122 is the frequency data f.
If it is not 3, then it is similarly detected whether it matches the frequency data f4 (step b22). In step b22, ll is stored in the frequency data storage area 122.
[! When the stored frequency data is not the frequency data f4, in step b22, the frequency corresponding to the frequency data stored in the frequency data storage area 122 is stored in the within-range frequency data storage area 135 provided in the RAM 83. It is detected whether the frequency is within the amateur band to be stored (step b23).

When step b23 is executed via steps b21 and b22, the frequency data stored in the frequency data storage area 122 is selected and excluded in step b19.
This means that it does not correspond to the frequency to be removed.

If the selection exclusion state setting means 134 is not set in step b2G, step b2G is followed by step b2G.
Two blocks b2B are executed. In this case, it is not determined whether the frequency data should be selectively excluded.

In step b23, the frequency data storage 1 rear 122
The frequency corresponding to the frequency data stored in the first timer 3 is a frequency within the amateur band.
0 timing is started (step b24), then it is detected whether the received signal level is below a predetermined level (step b25), and the received signal level continues to be below the predetermined level for the set time of the first timer 30. It is detected whether or not it has been done (step 26). If in step b26 the received signal level continues to be below the predetermined level for the set time of the first timer 30, then in step b19 it is determined that the frequency corresponding to the frequency data stored in the frequency data storage area 122 is an idle line. It turns out. Further, following step b26, frequency data storage area 1
22. The frequency data σA stored in the PI is loaded into the empty channel data storage area 136 provided in the RAM 83 (step b27). Following step b27, the frequency data stored in the S channel data storage area 123 is loaded into the frequency data storage area 122 (step b28).

Here, when step b28 is executed through step bti or step b17, what is stored in the empty channel data storage area 136 is frequency data f1 or chi2, and step b28 is executed through steps b20-b27. When the frequency data is stored in the empty channel data storage area 136, the frequency data (
