Hello, everyone, this is Ye Dada! Previous articles on BD4SJY! have also covered a lot of the basics of amateur radio, including the types of signals, how to set the channel frequency, and so on. Relatively speaking, they are more theoretical. There may be friends who can't understand it directly, so take advantage of the time to share some dry goods today, and teach you how to write the frequency of the device, as well as the problems that will be encountered in the setting process, etc.
Due to the large number of brands and models on the market, it is impossible to explain them one by one, so today I will select a few relatively common handsets to give you an explanation.
Before starting the official content, we need to know whether our device supports manual frequency, that is, whether we can get out of the computer software and set the frequency directly on the handset. The simplest way to distinguish most of the handsets is whether the machine has a numeric keypad or a touch screen that can directly input the relevant frequency. Here are a few pictures:
Hytera TD370 and Motorola SL2M (no keyboard, can only rely on computer software to preset the channel, cannot be temporarily adjusted)
Hytera HP780 and Motorola R7 (with keyboard, you can directly press the keys to adjust the frequency)
Yaesu FT3D (touch screen, frequency adjustment can be adjusted by manual touch)
Including the now common Quansheng UVK5K6, the frequency can also be changed by hand frequency. Therefore, in summary, the writing methods shown above are divided into the following types:
1. Hand set frequency, advantages: convenient, no need for other peripherals to change the relevant parameters, the flexibility is very high, is conducive to temporary grouping or temporary modification of frequency information when there is interference. Disadvantages: The operation is more complicated, to switch the menu page from time to time, some machines without Chinese display need to be used with the manual.
2. Computer writing frequency, advantages: perfect function, simple adjustment of handset parameters. The operation interface is clear at a glance, which is convenient for batch processing or copying data. Disadvantages: Relying on computer peripherals, it is not possible to write flexibly.
3. With the development of the times, many machines now also support Bluetooth connection to mobile phones, and frequency adjustment and machine settings are carried out through the APP on the mobile phone, which is obvious that it integrates the advantages of the previous two.
Of course, it is not that a certain model only supports one mode, and these three methods are compatible with each other. For example, Motorola's R7 can be set by hand or written by computer, and Hytera's HP780 is compatible with all the methods mentioned above. Personally, if the conditions allow, I like to write on the computer, because the function is perfect, the interface is clear, and the operation is not troublesome.
Of course, I also have to complain about Yaesu's frequency writing software, which is relatively complicated to set up, and it is also all in English, so many friends of Yaesu prefer to set the parameters of the machine directly by hand. Let's talk about Hytera, in fact, Hytera's frequency writing software is okay, but Hytera's frequency writing software has too many versions, which are incompatible with each other, and often make people dizzy, and several devices require several software. My favorite is Motorola, and multiple models use the same frequency writing software. High compatibility and good stability.
Let's take Motorola R7 as an example to give you a practical operation on how to write frequency.
1. Preparation
(1) Prepare our equipment, writing cable (some models come with some need to purchase extra), writing software (general dealers will provide it for free), and a Windows computer.
Motorola R7 and write frequency line
(2) Install the supporting writing software, and use the writing cable to connect the computer and equipment.
Connect to your computer
(3) Open the Motorola CPS2.0 writing software.
CPS2.0 software icon
(4) Read device information
Click Read
Reading
After reading, you will be redirected to the normal operation interface
2. Change the basic information of the device
(1) Click on the left menu to configure, the general settings under the subdirectory general.
(2) Modify the walkie-talkie alias on the right, we generally set our own call sign, walkie-talkie ID, fill in our international ID here, how to apply, please check the portal yourself.
Change the device information
3. Add an analog channel
(1) Click on the left area/channel assignment, the area here can be customized, just like our WeChat group friends have a reason, colleagues, relatives have a meaning. Click the number on the ➕ right, select Simulation, and click OK. Select the channel you just added, and click the pen button in the right area to edit it.
Add an analog channel
(2) Change the channel name, after changing here, it will be displayed on the device, which can be customized according to your needs.
(3) Modify the frequency (direct frequency), if you want to set the direct frequency to 438.500 as an example, just tick the two positions, enter the same rating. For more information on the differences between direct frequency and relay, please refer to the previous article.
Frequency of modification
(4) Modify the frequency table (relay), or take Wuxi relay as an example, the receiving frequency table 438.550 is filled in RX, and the lower difference is 6.2, then the transmitting frequency is 432.350 and filled in TX, and the transmitting subtone is 88.5, then modify the noise reduction type TPL, and the frequency is selected as 88.5.
Modify the trunk frequency
(5) After the change is completed, click Write, that is, the writing of analog channel, direct frequency or trunk is completed.
Complete the modification and write the settings
4. Add a digital channel
(1) Before starting to add, we need to select the address book to add a new group call number, and know about the portal with the group call number is not clear. Here is still taking Wuxi digital relay as an example, the group call sign is 460510, here we only need to change the ID and name.
Add 460510 groups
We said earlier that Wuxi Relay is a dual time slot, dual lane, and the other group is the national group, so here we can add another contact, the 46001 national group, as shown in the figure below. See for details on how to set it up.
Add 46001 groups
(2) Add a digital channel, click the number on the ➕ right, select the number and click OK. Select the channel you just added, and click the pen button in the right area to edit it.
Add a digital channel
(3) Change the name of the digital channel, refer to the parameters of Wuxi digital relay, adjust the color code to 9, time slot 1 is 46001 group, time slot 2 is 460510 group, then here first add time slot 2, 460510 group time slot selection 2.
Wuxi digital relay parameters
Change the name color code time slot
(4) Modify the receiving transmitting frequency according to the parameters, the key point is that the digital relay must select the contact name, because we choose the time slot 2, the relay is like a two-story building, the first floor is the national group, the second floor is the Wuxi group, only go to the second floor only with the access card (group number) on the second floor to be able to open the door and talk to the people inside, it is useless for you to take the password on the first floor to the second floor, so here we have to choose the group number of 460510, click to write and save.
Modify the frequency and contact
(5) Just mentioned the double time slot, so let's take a look at what time slot 1 is all about. At this point, let's re-follow the steps above to add a digital channel, change the name to the national group, the color code is the same as 9, and the time slot is changed to 1.
Add digital channels
(6) At this time, continue to pull down, you can see that the frequency is exactly the same as the previous channel, but the contact name is different, you can also understand that the phone number of a unit is the same, but you have to find someone to dial the extension number, which adds another (time slot) floor, as if the phone number is 431.350 (frequency) 1st floor (time slot) to call the national group 46001 (group number) 2nd floor (time slot) to call Wuxi group 460510 (group number)
Modify the contact name
(7) Finally, click Write, that is, the writing of the digital channel Wuxi Digital Relay, Wuxi Group and National Group is completed. In the end, we wrote four channels. As follows:
List of channels
In the end, we got four channels on the walkie-talkie, and we only need to select the channel after we take it out, so that we can communicate with the current frequency or the friendly station on the group in time.

The above is about R7 Writing Frequency Tutorial,There may be some models that are different,But the logic and principle behind it are actually the same,This is also the operation guide of DMR digital mode,It is recommended that you carefully read the manual after buying the device。 If you have any questions, please feel free to leave a message.
Written at the end, four-wheeled cars range from tens of thousands to millions of millions, the same is true for radios, and equipment from tens to hundreds to tens of thousands of dollars also abound, as a hobby, I hope everyone will enter the pit rationally, think twice, don't be blindly impulsive, and look at it rationally. If you encounter any problems, you can leave a message, as long as I know it will be answered for you, I wish you all a good time, and finally I hope you will move your little hands to make a fortune, like and follow and collect, play amateur radio and don't get lost, thank you!!
