Welcome to the STARCOM21 Statewide Illinois collaboration article, a Multi-State Public Trunked Radio System located in Illinois, Iowa, United States.
This is where you, the user, may index any articles you develop for scanning related topics for this Trunked Radio System.


  • Some talkgroups on this system may be using P25 Phase II TDMA modulation, which can only be monitored using a P25 Phase II capable scanner or receiver.

STARCOM21 is the Statewide Motorola Project 25 TRS in Illinois for public safety radio communications. The purpose of this page is to provide supplemental information to the Radioreference.com Starcom21 page.

Info on the Department of Innovation and Technology website

  • The network is owned and operated by Motorola Solutions and currently serves more than 45,000 subscribers from various State, local and federal government and non-governmental entities. It is a statewide, 700/800 MHz, Project 25-compliant, digital, trunked voice radio network that is open to all public safety and public service agencies in the State of Illinois. Non-State entities must work with Motorola Solutions directly to apply for network access. State agencies and non-State entities alike must complete a SC21 Oversight Committee System Access application to commence ordering equipment. SC21 services are coordinated and administered for State entities (State agencies, boards, commissions, etc., not including the General Assembly) through an agreement between DoIT and the Illinois State Police (ISP) Multi-Agency Communications Services Section (MACSS group).

SC21 also figures prominently in the Statewide Communications Interoperability Plan (SCIP), which establishes a single statewide platform for all public safety agencies to share emergency information. Managed by the Illinois Emergency Management Agency (IEMA), SCIP was developed by a consortium of federal, state, and local public safety practitioners working through the Illinois Terrorism Task Force's (ITTF’s) Communications Committee and the Statewide Interoperability Executive Committee. For more information on the SCIP please go to Statewide Communication Interoperability

WAVE Service

The STARCOM21 network supports a cellular broadband service through the Motorola Solutions Inc. WAVE Application. This provides the agency with the ability to connect their mobile smartphone to a STARCOM21 Astro25 Talkgroup or create broadband only talkgroups, these will not connect in any way to SC21. See WAVE PTX

Site/Tower Google Map

(NOT UPDATED) This may prove I have too much time on my hands, but I have taken all of the information from the CARMA profile and plotted all the transmit sites for StarCom using the "my maps" feature of Google Maps. Anyone wanting to check it out can go here: Link

A few things about the map:

  • After plugging in the coordinates for each site on the map I tried to locate the exact tower or structure used by a combination of satellite view, street view, and in some cases switching to Microsoft's Bing Maps for their Birds Eye view. If it still wasn't exactly clear I made a guess usually just putting the mark where the lat/lon coordinates landed me.
  • Pushpins are used for single site locations, blue for the north zone, green for central, and purple for south.
  • The "balloon" type pins are used on all simulcast sites, with different colors for each site.
  • At this time I included the county owned sites that use the same technology as StarCom including McHenry County (all of these being co-located with StarCom sites), Champaign's MDICE, and the St. Clair County system. My only regret doing this is that with all these sites included Google shows two separate pages for the sites, so not all of them are visible at one time on the map. I'm debating whether to take these sites out and make the map strictly StarCom so all the sites show up at once.

Google allows anyone with a Google account to make changes to the map, however I have it set up to only allow those that I invite to make the changes. If anyone is interested in helping to maintain the map or make corrections or additions to it, send me your e-mail address and I will add your name to the list. If you notice any errors either in locations of towers or the control channels listed and don't have a Google account or don't want to mess with the map, e-mail me and I will be glad to make the corrections.

Comments, praise, and even criticisms are welcome. -Mike McGowan - K9JPM

New StarCom21 tower map (Click here) - The above map has become outdated; I've attempted to reach the map owner to offer help to update the map, have not gotten a response. I have created a map that display updated and current tower locations for 8 digital systems within the state. Last update to the map for each system is in the description of the map. If you have any questions, comments, concerns please feel free to contact me. Enjoy! - Isaiah (Mex)
