I, too may be having this problem. I upgraded to K3 Beta 4.42 prior to putting my KPA500 in service. I had been using LP Bridge for years with great enthusiasm. Since installing the K3 firmware upgrade, LP Bridge fails and closes each time I attempt to use it to send RTTY with HRD when LP Bridge is in use. Without LP Bridge, no problem sending RTTY with HRD with no other change in setup. The problem is not related to the amp as it occurs when the amp is not connected. Thought the problem was LP Bridge, but uninstall and reinstall did not correct the problem.
