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. 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 )

What does this repeater stuff mean to me ? Whatever I say on the repeater channels can be heard over more than a 100 square mile area. If I travel away from Campus I must change the radio over to a Direct Channel to talk to other radio users near me. If there is interference when I use the repeater channels it might mean that the channel is in use by others. I should tell others when I switch channels to use the Direct Channels and switch back after I am done.

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.
