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

ECC Two Way Radios

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 are as a user to the Dispatcher.

The Digital Identification is unique to your radio within our system.

What are our responsibilities as a users of these radios ? We license these frequencies from the Government. We must be responsible and courteous to all other users

of these frequencies, all the time. These radio frequencies are monitored and reported to

the FCC if there is any behavior considered offensive, improper or disruptive.

If we abuse these rules we can be fined and/or disallowed from using these frequencies.
