DCARA has 3 sites that all share a common control radio frequency. This allows us to link some repeaters in half-duplex, as the control link radios are a single Motorola CDM1550.
All control radios operate on the same frequency, so linking a repeater to a control radio can be thought of as adding it to a group or pool.
To link and unlink certain repeaters, it is important to understand how these sites are internally configured.
