Hi, I have a dm1801 with a 2021 open gd77 fimware.
In my radio there is a "push-to-talk" (PTT) button operating mode that, when activated, allows you to start and stop voice transmission with two separate presses of the button, without having to hold it down during communication?
Thanks

Check PTT latch in the manual:

Perhaps a software update to a newer release might be an option to get all new and full features and solved issues and optimized code base.
