BACKGROUND OF THE INVENTION
The present invention relates to a radio having a squelch data changing function.
[0002]
[Prior art]
For example, in a VHF band or UHF band FM radio used in the United States, data of each channel is preset in a memory, and data can be transmitted / received in each channel in accordance with the preset data. FIG. 2 is a diagram specifically showing data preset in the memory. A transmission frequency, a reception frequency, transmission squelch data, and reception squelch data are preset for each channel. Here, the reception squelch data is data that enables communication with the partner device by opening the squelch of the subject device only when a squelch control signal of a frequency or code signal corresponding to the data is received from the partner device. The transmission squelch data is transmitted when the squelch control signal of the frequency or code signal corresponding to the data is transmitted from the own device to the other device, and when the other device has the same reception squelch data as the transmission squelch data of the own device. Data that opens the squelch of the machine and enables communication with the partner machine.
[0003]
These squelch data are preset in the memory as data of each channel as shown in FIG. 2, but have a function of temporarily changing this data for each channel. This is a preset data changing function, a so-called operator selectable tone (hereinafter referred to as OST) function. In this OST function, as shown in FIG. 3, for example, 16 sets (No1 to No16) of transmission squelch data and reception squelch data are stored in the memory. Then, for example, by pressing and holding the OST key of the radio for 1 second, the OST function is entered, and the initial value is selected as No. 1 transmission squelch data and reception squelch data. The transmitted squelch data and the received squelch data can be switched from No2 to No16. If such a selection operation is performed on each channel of FIG. 2, the transmission squelch data and reception squelch data of each channel are changed from the data of FIG. 2 to the transmission squelch data and reception squelch data of the OST function of FIG. be able to.
[0004]
Normally, in a wireless device, transmission / reception is performed in a state where the transmission squelch data and reception squelch data are set for each channel. However, there are cases in which transmission / reception is desired with the transmission squelch data and reception squelch data removed. For example, the received squelch data is removed so that the user can listen to the talks from all the other devices, and the transmitted squelch data is removed and the other device that has opened the squelch with the transmitted squelch data until now. It is a case to prevent the communication of.
[0005]
[Problems to be solved by the invention]
However, in the conventional OST function, it is impossible to set a state in which both transmission squelch data and reception squelch data are removed.
[0006]
On the other hand, the wireless device has a monitor function, and when the monitor key is operated, the reception squelch data is removed only at that time, and a state in which the conversation from all the other devices can be heard. However, the monitor function cannot remove the transmission squelch data.
[0007]
The present invention has been made in view of the above points, and an object thereof is to provide a radio having a squelch data changing function that can be set even in a state where both transmission squelch data and reception squelch data are removed.
[0008]
[Means for Solving the Problems]
Radio of the present invention is combined with the transmission of each channel becomes a pair squelch data and receive squelch data, preset by the pair are transmitted squelch data and transmitted from the squelch data of another pair squelch data to each channel In the radio having a squelch data changing function for changing to reception squelch data, the squelch data changing function stores N sets of transmission squelch data and reception squelch data which are combined to form a pair, and is stored by this means. N sets of transmission squelch data and reception squelch data are sequentially selected one by one, and selection means for selecting data other than the N sets of data, and the transmission squelch data and reception squelch one by one with this selection means when selecting data were the selected one Means for changing the transmission squelch data and a pair of transmission channels to squelch data squelch data and squelch data, when said selecting means is a state of selecting the other N sets of data, the transmission channels of the pair And a means for setting the squelch data and the received squelch data to a removal state.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a radio according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing only a main part of an embodiment of a radio apparatus according to the present invention. In this figure, reference numeral 11 denotes a CPU that controls the entire radio. An operation unit 12, a display unit 13, and a memory 14 are connected to the CPU 11. The operation unit 12 includes an OST (Operator Selectable Tone) key 15 and an up / down key 16 and inputs various signals. The display unit 13 comprises an LCD and displays various information such as a channel number and a squelch data number in the OST function. The memory 14 stores preset data for each channel and squelch data for the OST function. The preset data for each channel is the same as in FIG. 2, and the transmission frequency, reception frequency, transmission squelch data, and reception squelch data are stored for each channel. The squelch data in the OST function is the same as that shown in FIG. 3, for example. In this example, 16 sets (No1 to No16) of transmission squelch data and reception squelch data are stored.
[0010]
The radio as described above has an OST function, and transmission squelch data and reception squelch data for each channel is transmitted from transmission squelch data and reception squelch data (FIG. 2) preset for each channel. Data and received squelch data (FIG. 3) can be changed. Furthermore, according to the OST function of the present invention, it is possible to change to a state in which both transmission squelch data and reception squelch data of each channel are removed. Such an OST function of the present invention will be described below with reference to FIGS. FIG. 4 is a flowchart for explaining the operation, and FIG. 5 is a diagram showing how transmission squelch data and reception squelch data are changed and removed by the OST function of the present invention.
[0011]
Assume that channel 1 in FIG. 2 is selected as the channel. In this state, when the OST key 15 of the operation unit 12 is pressed for, for example, 1 second, the display on the display unit 13 changes from the display D1 in FIG. 4 (a state in which “CH1” channel 1 is displayed) to the display D2 in FIG. To the OST function. When entering the OST function, the transmission squelch data and the reception squelch data of No. 1 of the OST function of FIG. 3 are selected as initial values as can be seen from the display of “No 1” on the display D2. If the OST key 15 is operated again in this selected state, the selection is determined by the No. 1 transmission squelch data and the reception squelch data, and the transmission squelch data and the reception squelch data of the channel 1 are the No. 1 transmission squelch data and the reception of the OST function. Changed to squelch data. At this time, “CH1” and “OST” are displayed on the display unit 13 as indicated by display D3 in FIG. 4, and the transmission squelch data and reception squelch data of channel 1 are the transmission squelch data and reception squelch data of the OST function. It is informed that it has been changed.
[0012]
If the up / down key 16 of the operation unit 12 is operated while “No1” is displayed on the display D2 in FIG. 4, the transmission squelch data and the reception squelch data of the selected OST function are set to any one of No2 to No16. It is possible to switch over and return to the selection of the initial value of No1. At this time, as shown in display D4 in FIG. 4, the numbers of the selected transmission squelch data and reception squelch data are displayed on display unit 13. Then, if the OST key 15 is operated with the transmission squelch data and the reception squelch data of any of No. 1 to No. 16 being selected in this way, the selection is made with the selected set of transmission squelch data and reception squelch data. The transmission squelch data and the reception squelch data of channel 1 are changed to the transmission squelch data and the reception squelch data of the selected OST function, and the display on the display unit 13 becomes the display D3 of FIG.
[0013]
The selection by the up / down key 16 can be performed by switching to 17 stages. In the 1st to 16th stages, as described above, and as shown in FIG. 5, the transmission squelch data and the reception squelch of any of No. 1 to No. 16 of the OST function. Data is selected. On the other hand, when the selection by the up / down key 16 is in the 17th stage, since the transmission squelch data and the reception squelch data are not stored corresponding to this stage, the state other than the data is selected. In this state, the CPU 11 determines that the state has been reached, and the channel 1 transmits squelch data and received squelch data as shown in the selection state 17 in FIG. At this time, “No Tone” is displayed on the display unit 13 as shown by display D5 in FIG. If the OST key 15 is operated in this state, the data removal is confirmed, the transmission squelch data and the reception squelch data of the channel 1 are changed to the removed state, and the display on the display unit 13 is the display D3 in FIG. It becomes. The display D3 at this time means that the transmission squelch data and the reception squelch data of channel 1 have been removed by the OST function.
[0014]
If the OST key 15 is operated with the transmission squelch data and the reception squelch data of channel 1 removed or changed in this way, the transmission squelch data and reception squelch data of channel 1 as shown in FIG. Can be restored to the preset data of FIG. Further, if the OST key 15 is operated thereafter, the transmission squelch data and the reception squelch data of the channel 1 can be alternately switched between the preset data and the removed or changed state.
[0015]
Although the above description is for the case where the OST function is used in channel 1, the transmission squelch data and the reception squelch data can be changed or removed in the same manner for other channels. Further, the selection by the OST function can be performed by a switch other than the up / down key.
[0016]
According to the OST function, transmission squelch data and reception squelch data for each channel can be changed from data preset for each channel to data for the OST function, and transmission squelch data for each channel. It is also possible to change to a state where both the received squelch data and the received squelch data are removed. Thus, it is possible to realize a communication state in which the other device that has opened the squelch with the transmission squelch data so that the communication of the own device cannot be heard.
[0017]
【The invention's effect】
As described above in detail, according to the wireless device of the present invention, both the transmission squelch data and the reception squelch data can be set with the squelch data change function in a state in which both the transmission squelch data and the reception squelch data are removed.
