Since upgrading to SSDR 2.1 I have had my radio (6500) twice hang hard in the middle of a transmission. Only a long push on the power button brings it back. This never happened to me using 2.0 nor one of the latest 1.x s/w. Anyone else seeing this?
If you have not yet. Perform a factory reset on your radio. Make sure you Export your profiles before performing reset. Factory reset info can be found using the link below.
Once reset, Import your saved Profile settings.
