REPEATER AND DUPLEX OPERATIONS

I 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 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.
• Repeater settings can be stored into a memory channel.
