What do these numbers mean?
- Control channel

- The other frequencies the site uses for calls. A trunking scanner follows them automatically once it has the control channel.
- Site

- RFSS (Radio Frequency Sub-System)
- A group of sites run by the same controller. Large Project 25 systems can have several.
- NAC (Network Access Code)
- A hex code the site transmits. Your scanner can use it to ignore other systems on the same frequency.
