An ASL3 bug has been discovered where the transmitter stays keyed on boot.
With help from beta testers we have found that the problem appears on Raspberry Pi’s that do not have a realtime clock. Only the Rpi 5 has a realtime clock.
We’re working on a fix. In the mean time, restarting Asterisk will clear the problem and will not reoccur unless the Pi is rebooted.
