Well, it looks like we have some investigating to do. I listed to these talkgroups tonight, and they are no longer active (at least on the South Mountain site where I have heard them before). I cannot receive the White Tanks or Shaw sites from home to fully confirm.
IF these talkgroups are no longer active, they are either running their own system, or moved to another radio provider. Last time I listened to them, talkgroup 30 was very busy, and 39 was like an "event" channel. I monitored talkgroup 39 in the past when campus security officers were assisting with street closures around campus.
There are a few mobile freqs and only one repeater for GCU that I could find licensed. If anyone is close to campus, give these a listen.

If they are not on these freqs, see if anyone can get a close call hit on a repeater near campus. Otherwise, start searching talkgroups on some of the other DMR & NXDN commercial systems.
Have fun scanning!
