So something weird just happened with my SDS100. I have not had any noticeable issues since I bought this one. The last couple of days, I have been leaving it on all day/night. Today when I went home for lunch I noticed that it was unusually quiet. When I looked at it, it appeared to be "stuck" on a certain frequency (analog FD frequency in case this is at all relevant). I advanced it to scan forward but it did not receive anything for a few more minutes even though my others are running fine. I turned it off, and back on again, thinking the old "reboot fixes things" cliche. It seems to have been working for the remainder of the time I was home but I turned it off and am now back at work.
I didn't take the tax day update. But I don't know if my issue is the same as the others in this thread or not.
I really hope I do not have to send this thing in for repair and spend money on shipping and be without the scanner.
