Here are some key pieces of information:
First, the Jandu D75 machine (both Chinese and US versions) maintains consistent frequencies without any modifications. Broadcasting on 144-146 MHz or 430-440 MHz is straightforward, and there are no other users in China operating at these frequencies.😂
Second, when using the Type-C port on the Build ID d75 to charge, the charging time of 5.5 hours is relatively slow according to official specifications.
Third, it consumes power and is consistent with d74; standby mode with dual-guard does not require GPS, and lasts approximately 12 hours.
Fourth, the d75 has a built-in sound decoder and can transmit data via Bluetooth, allowing direct access to MMDVM when connected to a phone's Bluetooth. I have successfully configured it with very simple settings. The app can run in the background without affecting screen sleep mode, which is very comfortable. When using DSTAR, selecting "xlx074a" allows communication with 46001, and the audio quality is acceptable.
Fifth, the "建武 d75" button has been improved; overall, it's all made of a matte finish, which is slightly more durable than the d74.
Sixth, there are spare batteries available on Taobao, model KNB80L, which can be used with D74/75. The only downside to the battery is that it has a glossy finish, and they cost 85 yuan each.
