I have found control channels using close call. If I find a control channel for a trunk system and want to set up a system for it so i can scan it, how do I know what type of trunked system to set up to place it in?
Well, besides regular conversations for any kind of radio operation you can imagine (everything from public safety to business to media outlets etc), I particularly find it very entertaining to try to "sleuth out" all the bits and pieces of the trunk system - the talkgroups (channels in use), the data behind the system (the "system ID" which identifies the trunk system, for example, along with the frequencies in use, etc), and so on.What can you actually get out of scanning a trunked system?
The control channel sends a stream of data to your scanner telling the scanner which freq. to tune to for the Talk Group being used.. When the other person talks, it follows that Talk Group and it may direct the scanner to another freq. to continue the conversation.Once I place the control channel into a system, will it then populate the system with necessary frequencies? If so, can I scan it like that? Or do I have to place the frequencies into groups?
Yeah.. That's what my dad thought... He had his scanner (GRE-800) for about 3 months when he called me to say that the county system wasn't being received. I went over there and after a learning a little bit about the scanner programmed all the freqs for the system into the scanner. Worked fine after that.The control channel sends a stream of data to your scanner telling the scanner which freq. to tune to for the Talk Group being used..

"... The way I think the system works is that it checks to see what frequencies you currently have stored on yours system and only saves if it is unique. .
NO. It works as described above. The only freqs. you need in your scanner are the control channel freqs.
