12. 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 )

13. 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.
