Hello everyone! I have been learning a lot here at RR. Although, I have read much about StarCom21 there are a few issues I can not wrap my head around. For example, with this trunking system if I have one control channel frequency does this connect me to other towers (sites) statewide or do I have to program each control channel frequency for each individual tower? Anyone from southern Illinois? Does anyone have Skype? Apparently my county has no towers only bordering towers (my count: Clinton county). There is one tower in Clinton county but it is out of range (Junction City). Another question I have is that I'm getting transmissions from sites in my area but I don't understand how the system works. Could someone try to put it in layman's language for me?
Looking 4 StarCom21 better understanding

In addition to the information here download the StarCom21 Profile from the CARMA website at CARMA Profiles. There are many notes there that may help make sense of it all.
Basically for any site you only need to have the current control channel for most scanners. If you have a Uniden 396XT, 996XT or 996T then have a single "System" with several "Sites". In the System you enter in the local talkgroups as listed here on RR or from the CARMA Profile. For each of the nearby towers enter the freqs into Sites. Don't worry about entering too many Sites, if there is no received control channel the scanner will just pass it by.
You may be able to just load the free programming files from the CARMA website or the various scanner YahooGroups directly into the radio, or if you are a paid member here you can import it right from RadioReference.
StarCom21 tower sites are not located in specific counties for use in those counties. The sites are chosen for coverage and availability. The County names are provided as a geographical reference only to help users locate nearby towers. The tower used will vary and depend on many issues, so be sure to program adjacent towers into your scanner.
The system acts similar to a cellular phone system. There are many towers scattered thruout the state and a radio checks into towers (called affiliation) so that the system knows where to direct its messages. This is all done behind the scenes by computers and is fairly transparent to the users.
Enjoy!
