jamaal0299,
You need to provide more detailed information. There are far to many possible reasons to just guess blindly.
EXample: Did you make any programming changes to your scanner, from the time you last heard E. Cleveland to when you stopped hearing it? If no, then it's not a scanner issue.
One thing I noticed when I looked at E. Cleveland's PD listing in the RR Database. There's a note that says they sometimes use Speech Inversion Scrambling. It could be that they've decided to use Scrambling full time. Which means you won't hear them.
Another possibility is that they could have moved to the GCRCN system. Their FD is already on GCRCN.
The list goes on.
Provide some additional details as to what you have or have not changed. Hopefully you will get some answers.
