When pushing and releasing PTT 100:ths of time the radio can miss the PTT-off command a few times, as it's only sent once. When a command is only sent once there is not much to do about it, we can not change the Alinco program. I have informed them about this long time ago, and also about the problem that the radio can hang up, and need to be disconnected from 12V to start up again. But the firmware in the radio is not possible to update.
