Most of Lafayette Parish is still primarily on the 800 system. Carencro Fire uses the 700 system as primary unless they are in a mutual aid situation. Everyone else is still waiting to switch over when all the necessary equipment is in place in all dispatch centers.
As far as encryption, ALL 700 talkgroups in Lafayette Parish are Encrypted with Motorola ADP encryption. This of course does not include any mutual aid talkgroups or shared talkgroups. This is not rumor, all radios have been programmed with encryption since inception, and there are no plans to discontinue it's use. So when the switch is made, they will in fact be un-monitorable.
