Description

[Detailed description of the invention] ``Purpose of the invention'' (Field of industrial application) This invention relates to a wireless communication device using a duplex method or a semi-duplex method, and in particular, it is capable of writing and reading reception and transmission frequencies into memory. The present invention relates to a frequency memory device for a wireless communication device suitable for use in a wireless communication device.

(Prior art) A duplex system in which reception and transmission operate at different frequencies and reception and transmission operate simultaneously, or a semi-duplex system in which reception and transmission operate at different frequencies and reception and transmission operate alternately. 2. Description of the Related Art Some wireless communication devices are equipped with a frequency memory device in order to avoid having to manually set a frequency each time depending on the communication partner.

To write to this frequency memory device, first, manually set the desired receiving frequency and then enter the memory operation, which will cause a beep sound or a display lamp to light up. (hereinafter referred to as beep etc.) Then,
When the input switch of the memory device is turned on, the reception frequency is written to the memory device.

At this time, a beep sound or the like is displayed to confirm the memory operation. Further, while this beep sound etc. continues to be displayed, if the transmitting frequency is set and the input switch of the memory device is turned on, the transmitting frequency is written into the memory device. At this time, a beep sound or the like is displayed to confirm the memory operation.

The writing location of the above memory device is
If the receiving frequency and transmitting frequency are paired, and the writing order is, for example, as described above,
"Write the transmit frequency after the receive frequency"
It is predetermined that the data can be read out in pairs by turning on the readout switch.

Furthermore, as frequency memory means other than those described above, there is also a wireless communication device configured so that the input switch and memory readout switch of the above-mentioned memory device are operated by operating a channel switch. That is, in this wireless communication device, by operating the channel switch, the input switch and read switch functions of the memory device are performed simultaneously with the instruction of the write location.

(Problem to be solved by the invention) However, in the above-mentioned conventional wireless communication device, the order of writing in the memory is fixed, for example, first the receiving frequency and then the transmitting frequency, so during the receiving operation To memorize the frequency for transmission, temporarily store it by other means,
First, it was necessary to write the reception frequency into the memory device, and then write the transmission frequency that had been temporarily stored in another memory means. Also, to exchange the receiving frequency and transmitting frequency stored in pairs, do the same as above, by temporarily writing in another memory means and then inputting the receiving frequency and transmitting frequency into the memory device in order. I had to.

In addition, it was troublesome because it required two operations: setting the receiving frequency, turning on the memory input switch, then setting the transmitting frequency, and then turning on the memory input switch again. In particular, if you do not memorize the receiving frequency and then the transmitting frequency,
The problem was that the beeping sound continued to be heard, making it appear as if there had been a malfunction, and the wireless communication device would stop working.

This invention was made in view of the above points, and its purpose is to facilitate memory manipulation of reception and transmission frequencies in duplex or semi-duplex wireless communication devices. An object of the present invention is to provide a frequency memory device for a wireless communication device.

"Structure of the invention" (Means for solving the problem) Fig. 1 is a functional block diagram showing the structure of this invention. Has two 3V VFO memories that constantly write data,
VFO variable means 10 for manually controlling the frequency of the PLL synthesizer 12;
A selection switch 9 selects the VFO memory 3V and inputs the data of the reception frequency and transmission frequency, and the two VFO memories 3 selected by the selection switch 9
A frequency display section 11 that displays the frequency of data input to one side of the VFO memory 3M, a main memory 3M that allocates data on the reception and transmission frequencies of the two VFO memories 3V and writes them in pairs, and two VFO memories 3V.
The problem is solved by providing an input switch 7 that reads out the data and inputs it to the main memory 3M, and an output switch 8 that reads out the data of the main memory 3M and transfers it to the two VFO memories 3V.

(Operation) When the VFO memory selection switch is used to instruct whether to write reception frequency data or transmission frequency data to either of the two VFO memories, the frequency display section also displays the frequency of the designated side. The operation of the VFO variable means also acts on the side specified by the selection switch. When data from two VFO memories is written to the main memory according to instructions from the first input switch of the main memory, the side specified by the selection switch is allocated to the reception frequency, and the other side is allocated to the transmission frequency.

The output switch that transfers the data in the main memory to the two VFO memories reads out the paired receive frequency and transmit frequency data from the main memory. At this time,
Regardless of which side of the receiving or transmitting frequency is indicated by the selection switch, the frequency display section displays the receiving frequency, and the transmitting frequency is read out on the side to which the selection switch is not instructed. Depending on the reception/transmission operation information, frequency information read from the main memory is output to the PLL synthesizer in accordance with each operation.
