Ever since I got my FLEX-6700 back from the PEN, SmartSDR v1.3.8 has not been as stable as it was before the hardware upgrade.
Previously, I could lave the radio powered on 24/7, only shutting down the client. Now, if I shut down the client & leave the radio powered on for an undetermined period of time, the client will crash on startup with the error screen shown in the picture. The main error message is "Safe handle has been closed". To recover, I have to turn the radio off & back on again.
I have not determined the length of time the radio must be idle for this to occur. Usually I an away from the radio for an hour or more.
I just finished a week of operating W1AW/9. This involved several 2-hour shifts of nearly continuous operating. The problem never occurred while I was actively using the radio, only when I shut down the client & come back later.
