The actual frequency pair used is assigned by a local frequency coordinating council.

The duplexer is a device which prevents the repeater's high-power transmitter on the output frequency from drowning out the users' signal on the repeater receiver on the input frequency. The system is used by Icom and other digital radios, and there is a network of D-Star compatible repeaters in some countries. Voting systems require no knowledge or effort on the part of the user - the system just seems to have better-than-average handheld coverage. In some areas multiple repeaters are linked together to form a wide-coverage network, such as the linked system provided by the Independent Repeater Association  which covers most of western Michigan, or the Western Intertie Network System "WINsystem" that now covers a great deal of California, and is in 17 other states, including Hawaii, along with parts of four other countries, Australia, Canada, Great Britain and Japan. There are also digital amateur TV repeaters that retransmit digital video signals.
