Trackball is often defective in these radios.BH7HQT wrote: ↑Fri Mar 01, 2024 5:30 pmI used the Alpha 2.2 version Firmware on a MD-780(TYT MD 2017 Chinese Version,no GPS module avaliable)。
The firmware works well,I succesfully make a QSO by ARISS.
The trackball does not worked very well both in High and Low modes.(Up or down needs two or three times movement.)
More test is needed.
Thanks for your work on OpenGD77.
Many people prefer to use the side buttons and P1 / P2 instead
Because the trackball is so unreliable, we disable it's use by default, and the user must enable it in the Options
