Yes, the statute is clear Indiana defines a police radio as such. The legitimate work around is get an amateur license or make your vehicle your workplace.The clandestine option is don't get caught. Back in '95 I had a Pro 43 taken and got a ticket for it. Since the Feds regulate radio guess what? Got the scanner back and the ticket went away. I think I still have the physical ticket somewhere.
Years ago I was with my brother and we were traveling in Indiana. We had pulled off the interstate to get some breakfast. There was an accident scene at the bottom of the off ramp. Later my brother said the cop gave us a dirty look. All I had at the time was a ham HT connected to a magnet mount. I didn't know about the scanner prohibition, but we were from out of state. so I won't have known about it like you do now.
