Duplex

General
Your radio has a Repeater Access function to allow use of local repeater 

stations (if available in your area). Repeaters are shared radio systems 

installed by interested parties (clubs, local business etc.) that receive 

transmissions on specific channels and re-transmit (or repeat) the 

received signal to another channel.

Repeater Station 

The Repeater Access function can be set (from channel 1 to 8 and 41 

- 48) used by local repeater stations. When activated, your radio will 

receive the Repeater on its specific channel (all repeater outputs are on 

channel 1 to 8 and 41 to 48) but transmit to the repeater channel 31 

through 38 and 71 to 78.
(Factory default is set to On for all repeater channels).
e.g.
CH01 on Duplex mode will receive on CH01 but transmit on CH31.
CH02 on Duplex mode will receive on CH02 but transmit on CH32.
If you transmit on CH01 duplex mode, you are actually transmitting on 

CH31.
The repeater station receives your signal on CH31 and retransmits on 

CH01.
Your UHF radio allows you to pre-select Duplex operation individually 

on each channel.
