Very strange thing happened this morning. Had a difficult time upgrading to the Beta version of SSDR and had to attempt a reboot during upgrade. Eventually the radio recovered and SSDR was working great. I powered down the Flex. Went upstairs came back about two hours later and fired it up. The radio led started blinking red and I got an error message beginning with PSLV - (something) and locked up. I shut down the power supply and turned it back on and the radio seemed to function fine after that. Sorry I could not get the exact message (had a .75 in it). Hoping it was a one time event related to upgrade but was wondering if anyone else had seen this after upgrading to the beta.
