系统版本V3.03, 数字固件01.00.00.49 系统写频方法软件中有说明。数字固件浏览先选择固件，选择端口，选择波特率115200，点击开始烧录。然后对讲机按住菜单键开机，自动开始擦除并写入。通讯录暂时不建议操作，厂家已经内置了26万联系人。我试了一次更新通讯录，变砖头了。。。。。最后提示，写频有风险，操作须谨慎链接：https://pan.baidu.com/s/1TwcCS6K87lMdhsiUjDKU4A?pwd=tgt2 提取码：tgt2

版本号：V3.09 1. 修复收发异常的问题 2. 修复数字监听常开的问题 3. 修复上一版新增的信道切换方向反向无效的问题 4.新增菜单“对讲机设置”->“数字载波指示灯”，用以控制有载波不接收情况下是否亮绿灯 5.更改“组呼时显示”的菜单为“被呼时显示”,选择“主呼方信息”时，第三行信息将显示城市等信息，否则显示被呼ID及主呼方色码 6.修复定时出现提示音的问题 7.最底下小字部分，色码CXX后增加-M表示该频道开启了数字监听

这个机器很神秘，到处找不到支持文档/固件，抖音倒是有董哥定制，可惜要从他那里买 TNX OM，求一个写频软件，作为DMR收听台还是可以凑合用的，可惜抗干扰能力太差，U段一发射就挂，这个价位只能当玩具了。

连上电脑没有端口，需要安装电脑驱动吗

@"BG4TRF"#p38702 电脑安装写频对应驱动就行

@"BG4TRF"#p38698 分享文件里有对应版本的写频软件

关于通讯录更新：先去radioID网站，在datebase页面下载最新的通讯录。uv4r下载倒数第二个user.csv文件，然后在写频软件通讯录一栏，按照要求上传和更新即可。自己刚刚试了一下成功更新。

@"Billrizer"#p38785 感谢，无论我开机状态还是关机状态插上电脑以后没有新硬件设备提示，好像进入充电模式了。正常起码要有一个硬件才可以安装对应驱动吧？ win11x64 求驱动，谢谢。

@"Billrizer"#p38785 忽然发现要用写频线，是K头吧？TNX

@"BG4TRF"#p38890 写频使用通用K头线即可。tapy-c只能充电

Latest firmware for iradio UV4R (both system and digital)

Billrizer

System version V3.03, digital firmware 01.00.00.49
The software for the system write frequency method includes instructions.
To browse the digital firmware, first select the firmware, then select the port and baud rate (115200), and click "Start Programming". Then, press and hold the menu button on the radio to turn it on, and it will automatically erase and write.
I don't recommend using the address book yet, as the manufacturer has already pre-loaded it with 260,000 contacts. I tried updating it once, and it bricked my device...
Finally, please note that writing frequency carries risks, and operations should be conducted with caution.

Billrizer After I updated it, the screen always shows a yellow light and doesn't display anything. Is it bricked? How did you fix it?

How to update your contact list

BG6UFA

What are the differences between V2 and V3?

BG4TRF

This machine is quite mysterious; I can't find any supporting documentation or firmware, but Douyin has a version customized by "Dong Ge." However, it's only available for purchase from him.

Thanks, OM. I'm looking for a voice recording software that can be used as a DMR receiver/recorder. However, its interference resistance is too poor; it immediately cuts out when receiving U-band transmissions. At this price point, it's really just a toy.

Billrizer

BG4TRF The shared document contains corresponding version-specific writing software.

BD8FKQ

BG4TRF 确实。

Watermelon

BG4TRF 如果把董哥定制的EEPROM，拷到普通版本上不知道行不行

BG4TRF

If it doesn't connect to the computer via a port, do I need to install drivers for the computer?

Billrizer

BG4TRF Install the appropriate driver for the recording device on your computer.

BG4TRF

Billrizer Thank you. After plugging in my computer, whether it's turned on or off, I don't see any new hardware prompts. It seems like it's entering charging mode. Shouldn't there be at least one piece of hardware for installing the corresponding driver? Windows 11 x64, requesting drivers, thank you.

BG4TRF

Billrizer Suddenly realized that I need to use a write-frequency line, and it's a K-head, right? Thanks.

Billrizer

Regarding updating the contact list: First, go to the radioID website and download the latest contact list from the database page. Download the second-to-last user.csv file for UV4R, then upload and update the contact list in your recording software according to the instructions. I just tested it and it worked successfully.

BH2WBA

Billrizer Have you updated all the files? Can you please either upload them or filter out specific ones, such as those related to China's imports?

BH4KQJ

Billrizer 谢谢分享

Billrizer

BG4TRF You can use standard K-type cables for writing frequencies. The tapy-c device can only be charged.

BI7BKE

Thank you, dear.😭😭
The UV4R player has finally found the file.😭😭

Billrizer

BH2WBA All updates have been applied; no filtering has been used.

Billrizer

BH2WBA Did you use the wrong frequency software? The 1015 software is only for adding contacts worldwide. I've sent a request to add you on WeChat, and I'll send you the new QSL card.

Billrizer 老兄，能提供写全球联系人的软件吗？？

Hello, can the original machine with the original storage chip be flashed with your firmware? DE BD4WQZ, 73!
