If you look it says the Indiana Project Hoosier SAFE-T net is used primarliy by DNR! Those frequencies you circled may not be used at all, or very little in case the P25 system goes down. It is not as simple as plugging in those two. It takes a scanner capable of Phase 1 P25 reception. There are many on the used market, the 396XT is a portable, the 996XT a base unit. An old HomePatrol 1 would also work. There are others, a few made by Whistler, but I'm not familiar with them.
You just no longer just plug in channels, frequencies. The scanner scans a group of frequencies in the background, and stops when a talkgroup you have entered is used! Allows for many more users. You would program the Horton and District 52 sites as GTO_04 mentioned and then the talkgroups for DNR.

Sadly it ain't as simple as it used to be. Hoping someone close to you offers help and guidance.
Good luck...
