I have a very annoying problem. The radio unit connected to my IC-706 resets itself about 20 minutes after connecting. The red LED (AUX/MIC) lights up on the control unit and everything freezes. The SIP error shows up on the control unit webpage. When I go to the radio unit webpage I can clearly see that the uptime is like a few seconds. Checked with different power supply - no changes. The problem shows up also when RX-only, so it's not caused by RFI.
Does anyone know how to fix this problem?
I'm attaching a screenshot from "Info" section on radio unit just after the self-restart.
