I appears Norman's site 40 the old analog site has been disabled and P25 site 41 has taken over the site 40 communications from the same location @ OU Energy center.
Yep this happened last week sometime. Norman PD and Fire and OU are using this as well as their dedicated Norman simulcast site. I have noticed much more activity on the new system recently.
Tom as far as I can tell they are not using any old freqs as things stand now. I am able to copy all the traffic with my 796D on site 41 even Norman fire and PD traffic. SO if things stay like they are you don't need a SDS200/100 to copy the traffic.
