What do these numbers mean?

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.
