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

Others monitoring this channel can hear what you say.
