What do these numbers mean?
- Control channel
- The frequency your scanner listens to first. It tells the scanner where each voice call is happening, so program it before anything else.
- Voice
- The other frequencies the site uses for calls. A trunking scanner follows them automatically once it has the control channel.
- Site
- One tower location of the system. Scanners show the number in decimal or hex, so both are listed.
- 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.
- Talkgroup
- A virtual channel on a trunked system, such as one agency’s dispatch. Programming uses the decimal or hex number, depending on your scanner.
