Countywide Law Enforcement

All police departments in Ingham County have a number designator assigned to the department.  
Most departments use this number as the first digit in their unit number. 
The last number correlates to badge number in smaller agencies, or in larger agencies correlates to shift and/or district.
Lansing has their own dispatch channels, East Lansing/MSU have their own dispatch channel, and all other units share an out-county dispatch talkgroup. 
The tac channels are often setup to scan and also pick up traffic on the main dispatch channels.

Ingham County and Michigan State Police generally do not like and stay away from 10 codes- the official Ingham County list has about 90 of them, but most have not been heard on the air in years. The ones above are the few that are still used semi-regularly.

For offense codes see the wiki page for Michigan State Police. Offense codes are rarely used in Ingham county.

DISPATCH CHANNELS
33SPEV1-10: Used during county events, as well as for training scenarios. Replace 'CW event' channels on old Harris system.
33ICMAIN  : Used by Sheriff, Meridian Township, MSP, Stockbridge, Webberville, Williamston, Delhi Township, Leslie. “County main”
33ICOPS   : used during complicated events such as manhunts or vehicle chases. Utilizes full-time ADP encryption. Used during some county-wide or out-county events. Also can be used to carry confidential information. Can be used for dispatch when it is suspected the subject has a scanner.
33ELMSU   : Used by East Lansing PD, Michigan State University DPPS, East Lansing Parking and Code Enforcement for dispatch.
33MSUTAC  : used for MSU PD car to car, also used by various MSU security departments, security operations center, etc for inter-department communications and other ops. Full-time ADP encryption. Much more busy than other Ingham agencies' 'tac' channels.
33ELMOPS  : Not used for dispatch of police, used by same agencies as 33ELMSU. Utilizes full-time ADP encryption. Used for dispatch-type information as well as complicated communications. 
33LANORTH : Used by Lansing PD (north side), and south side after 2 AM. “Metro north”
33LASOUTH : Used by Lansing PD (south side). Also used by Lansing Township. “Metro south”
33MSUSPEV : Used by MSU Green Coat Security, as well as for interop between police and others during events, and by police during events. “Spev”
33ACMAIN  : Used by Ingham County Animal Control. They seem to have transitioned to using ICMAIN.

33LCCPD   : Used by Lansing Community College police and security.
33DPSCO   : Used by Lansing schools Department of Public Safety.
- MSU Breslin Center, Special Events, and several campus security divisions use analog UHF radios that could talk to the old Harris radios and had patches to that system. Most Breslin Center activity is on 469.75 MHz, most Special Events is on 462.6. Most of these groups have MPSCS capability but prefer to use their old analog radios for whatever reason. LCC also has a few departments on analog UHF radios. These are the last holdouts on UHF analog, after MSU Parking Enforcement and Greencoat Security in 2024. All other county security, law enforcement, public safety, as well as most public works are now on the MPSCS since 2021. MSU Special Events plan to get onto the MPSCS eventually. Breslin Center may eventually transition to DMR. Some of Ingham County’s Motorola base and mobile radios (all public safety radios serviced by the state) are multi band models to maintain interoperability with old UHF systems (such as those non-PS systems installed by State Electronics, Mobile Communications America, Communcations Services, etc). Most of these base stations however are flashed for 700/800 MHz only. All handhelds are now 700/800 only. Previously, when everyone was on analog UHF, many police radios had local schools, some businesses, etc programmed into their radios with usage agreements, but this is no longer possible without patches as the county has moved to 700/800 P25 and many schools and businesses have been convinced to move to UHF DMR. Many schools, public works, services, etc, have realized this issue and have ditched their relatively new proprietary DMR systems for MPSCS subscriber units since 2021.
- All MPSCS-capable Ingham law enforcement radios have access to 33COM, 33ICMAIN, 33INGFIRE, 33ELMSU, 33LANORTH/SOUTH, 33LEIN, 33ICOPS, 33ELMOPS, 33LANOPS, 33LASOPS, 33P911, MPSCS event channels, 700-MHz simplex, and 33SPEV1-10, and tri-county mutual aid channels. Each agency also has their own car-to-car talkgroups, some have detective bureau talkgroups, and police dispatch talkgroups for nearby counties.
- Each department has their own proprietary tac channel, and a few have several, as well as shared ops channels. Generally, 'tac' channels are in the clear and 'ops' channels are encrypted. Tac channels are car-to-car type talk and ops channels are for dispatch information that is secured from the public, and also used during some complicated multi-jurisdiction events to keep information secure and avoid tying up dispatch channels.
