4REPEATER OPERATION■ GeneralRepeaters allow you to extend the operational range of yourradio because a repeater has much higher output power thanthe typical transceiver.Normally, a repeater has independent frequencies for eachreceiver and transmitter.A subaudible tone may also be required to access a repeater.Reference amateur radio handbooks and local ham magazinesfor details of local repeaters such as repeater input/outputfrequencies and locations.Repeater example;Receives the 434.540 MHz signaland the detected audio signals aretransmitted on 439.540 MHz simultaneously.• Repeater operation flow chartStep 1:Set the desired band to operate the repeater.Step 2:Set the desired receive frequency (repeater output frequency).Step 3:Set the duplex (shift) direction (– duplex or +duplex).- Set the offset frequency (amount of shift), if required.Step 4:Set the subaudible tone (repeater tone) encoder function ON.- Set the subaudible tone frequency, if required.• Repeater settings can be stored into a memory channel.Station A:Tx: 434.540 MHzRx: 439.540 MHzStation B:Tx: 434.540 MHzRx: 439.540 MHz29
