设备：特易通MD-UV390plus 系统：opengd77 25.03.23beta版(中文版) 文档来源：https://github.com/LibreDMR/OpenGD77_UserGuide/blob/master/OpenGD77_User_Guide.md 由于英文版太长，制作了中英对照版，并找豆包帮忙总结了一下，给大家分享一下。因为上传不了附件，[下载链接](https://www.123865.com/s/1KqLVv-rRGod?pwd=MpU1#)在此，需要交流的可以在此回复。注意：opengd77写入频率、联系人和APRS信息都需要写频线，所以一定要准备一根对应厂商的写频线，否则无法识别。

gd77是我目前遇到过最强大，最好用的固件！

@"BH1AYY"#p86131 体验确实不错，但是已经半年没有更新了，论坛也挂了，且行且珍惜吧

@"y010204025"#p86202 受众太少，不过资源没废就是万幸！

@"BH1AYY"#p86213 现在能刷机的，好像只有K5，K6还有就是opengd77的几款，也算是不错了

@"y010204025"#p86202 后续应该是无了

@"BH6RZW"#p86219 有一个就算不错了，应当珍惜

Device: EasyComm MD-UV390plus
System: opengd77, version 25.03.23 beta (Chinese version)
Document Source:https://github.com/LibreDMR/OpenGD77_UserGuide/blob/master/OpenGD77_User_Guide.md
Due to the length of the English version, I have created a bilingual (English and Chinese) version, and I asked "Doubao" for help summarizing it. Here is the summary:
Because I cannot upload attachments.Download linkHere, you can reply to initiate communication.
Note: The write-enable frequency, contact information, and APRS data for the opengd77 must be written using a specific write-enable cable. Therefore, it is essential to have a cable that is compatible with the manufacturer of the opengd77; otherwise, it will not be recognized.

The power adjustment data for the MD-UV390 plus, after flashing "opengd77" on the MD-UV390, seems to be inaccurate. I borrowed a power meter from SFW to calibrate it. Since the power differs when the device is placed horizontally and vertically, I've provided calibration data for both placement methods so that other users of the same model can refer to them.
