Important Note:
  • Radios contain both Simplex and Repeater channels
  • Know which channels in the radio are simplex and which channels require a repeater
  • Radio users must be in range or within the coverage area of an active repeater to use repeater channels
  • If a repeater is not available, use a Simplex channel as long as you are in range of other users on the same channel
  • Mobile radios have greater range than portable radios
  • A repeater channel has greater range than a simplex channel.
