Uniden UH-090 - Manual (Page 9)

Using Repeater Channels (FM Only)
The Signal coming from your radio is received by the Repeater Station and then retransmitted at the same time
on another channel. This operation is called "Duplexing".
For example,
CH01 on Duplex Mode will Receive on CH 01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH 02 but Transmit on CH32 etc ....
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31, the repeater station down-converts
your signal and retransmits on CH01.
Operating the UH-090 in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for repeater use.
