4 REPEATER OPERATION

General

Repeaters allow you to extend the operational range of your radio because a repeater has much higher output power than the typical transceiver.

Normally, a repeater has independent frequencies for each receiver and transmitter.

A subaudible tone may also be required to access a repeater.

Reference amateur radio hand books and local ham maga- zines for details of local repeaters such as repeater input/out- put frequencies and locations.

Repeater example;

Receives the 444.540 MHz signal and the detected audio signals are transmitted on 449.540 MHz simul- taneously.

Station A:

Station B:

Tx: 444.540 MHz

Tx: 444.540 MHz

Rx: 449.540 MHz

Rx: 449.540 MHz

Repeater operation flow chart

Step 1:

Set the desired band to operate the repeater.

Step 2:

Set the desired receive frequency (repeater output frequency).

Step 3:

Set the duplex (shifting) direction (– duplex or +duplex). - Set the offset frequency (shifting value), if required.

Step 4:

Set the subaudible tone (repeater tone) encoder function ON.

-Set the subaudible tone frequency, if required.

The IC-208H USA version has the auto repeater function. Thus the steps 3 and 4 may not be necessary, depending on the setting.

Repeater settings can be stored into a memory channel.
