cleveland county

I live in Norman and programed my scanner with the Norman site. One of the groups (52208) cleveland County Jail, I have not heard anything on. Am I missing something? Is it encrypted or did they change the talkgoup? Just wondering if anyone knows.

Trying to find the freqs for ELS in OKC OK Cleveland county area. I have found a freq through FCC search, I was just wondering if it's a simplex or duplex frequency, and does it have a tone? Any help would be appreciated
