unidennewbee,
Lake County is the only county in this area that is still on conventional frequencies. 155.685 for Law Enforcement, 154.430 for Fire, and 155.220 for EMS Dispatch.
All the counties surrounding Lake are on MPSCS. Manistee, Mason, Oceana, and Newaygo have been on MPSCS for some time, and Wexford, Osceola, and Mecosta have switched within the past year.
These digital scanners can be pretty daunting. I got a Radio Shack PRO-106 about 4 years ago, and it took a little while to figure out. I originally programmed by hand, then later got Butel's ARC500 to clean up the resulting clutter, LOL.
I hope this helps,
-Gary
