Yes -
Generally, systems that the radio cannot scan are X'd out in the software.
Having said that, I think the Cobb County X is misleading because Cobb County system is marked as P25 Phase 2 in the RRDB and the radio doesn't do P25 Phase 2. However, looking at the system, the talkgroups do not appear to be marked as being Phase 2.
I think I've seen some posted work arounds for this but if normal else, you could try creating and/or programming the Cobbs County system manually to see if the RRDB information is accurate.
