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 by the Dispatcher when you’re needed.

Every time that you transmit on the radio the
Identification Number is sent to identify who you
