2023-12-27 12:38:54 65
版本 :V3.4.5

Date: December 27, 2023
1. Solved the bug of tuning and restarting in Tiandiao.
Date: December 19, 2023
1. Solved the black screen issue during startup.
2. Further stabilized the relay on DMR, with the test relay being Hynix RD980
3. The adjustable power has been added, but the adjustment speed has not yet reached the ideal fast and precise control, and further algorithm improvement is needed. In fact, this feature has already been added in one release. The hardware reason for the 144MHz band NFM mode cannot be changed.
4. Fixed bug with incorrect display of approval code.
Date: December 5th, 2023
1. The network port driver has been added, and the protocol layer needs to be further increased.
2. Improve the issue of interfering with buttons during transmission.
3. Modifying the encoder cannot correctly control parameter bugs.
4. Fixed a bug where the input method window cannot exit.
5. The issue of DMR modification not being able to connect to the relay is currently not very stable and requires further improvement.
6. Added high power range for UV section, but try to use low power range as much as possible. High power range may damage the radio station due to the lack of correction parameters during early shipments.
7. Fixed the issue of not being able to receive after pressing PTT in radio mode, and changed it to prohibit transmission in radio mode.
8. The transmission frequency can also be modified during transmission.
9. The algorithm for continuous tuning in Tiandiao has been removed.
Date: March 16, 2023
1. Fix the issue of insufficient frequency offset in NFM mode.
Date: March 20th, 2023
1. Fix DMR call boot mode incorrect.
2. Add MPU6050 driver.
3. Fix the issue of channel not being able to save.
4. Add write channel function.
5. Add shortcut buttons for DMR settings menu
6. Supports direct frequency operation and relay operation in DMR mode.
6. Increase compatibility with Hynix and Motorola walkie talkies.
Date: August 22, 2022
1. Solve the problem of insufficient regulation of NFM mode.
2. Add mouse driver, mouse can serve as encoder.
3. Increase GPS data output through serial port.
4. Resolve the issue of channel storage data errors.
Date: August 22, 2022
1. Solve the problem of insufficient regulation of NFM mode.
2. Add AFO interface to output different audio in different modes, making it easier to connect to external speakers.
Date: June 7th, 2022
1. Switch Bluetooth input to headphone audio, and when using Bluetooth FT8, the speaker can be turned off to play FT8 without affecting each other.
Date: May 4th, 2022
1. Solve the problem of transmission frequency offset.
2. Open user calibration interface, providing frequency, voltage, and S-meter calibration.
3. Solve the problem of no sub tone transmission in NFM mode.
4. Add support for new local oscillator drivers.
