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?
