Here's what I've been able to find out about the State of Louisiana radio system which is utilized by the State Police:
How do I tell if this is a digital or analog system? What about encryption?
Would a scanner as simple as the RadioShack Pro-83 work?
What about the Highway Patrol alert on a scanner like the BCT-8, would it work with this system.
If this is a digital system I probably won't bother because they're too expensive right now.
