What is the difference between a repeater and
direct channels ?

• Repeater low powered signals from portable
  radios are amplified and retransmitted to a much
  larger area from a high powered base repeater
  station.
• Repeater channels only work when the portable
  units signal can reach the repeater radio to
  operate. 250 Square Miles
• Direct low powered portables can talk from one
  portable unit to another portable unit directly
  without the use of a base repeater.
• Direct radio channels allow portable units
  to operate anywhere a repeater in not available.
  ( Distance is limited ) 6 Square Miles

What is Private Line ?

• Allows groups of radio users to share radio
  frequencies without listening to conversations or
  interference from other users of the same
  frequency.
• Gives the user the perception that no one else is
  using this frequency.
• Makes it easier to tell when someone is trying to
  reach you or someone in your workgroup.
• Make communications more clear and concise.
• Masks the communications of other users of this
  frequency.
• Private Line does NOT scramble the signal. Others
  monitoring this channel can hear what you say.

What does Digital Identification mean ?

• The Identification Number allows you to be paged

  radio within our system.
