I have to pipe up on this one. Coordinated repeaters are a nice thing, but they are not absolutely required. If you place a repeater on the air, with proper PL access etc, and notify the coordinator of this, they still have to consider your machine when coordinating another. This has worked in cases where these repeater coordinating groups have played favorites - and it will prevail. While the coordinated repeater will have the function of coordination behind them, the coordinating committee does not have the authority to assign exclusive use, not does it have the authority to disregard sound pracice - like ignoring a certified letter advising them of a repeater on the air. The FCC has stood behind tone access vs carrier access as teh appropriate way to resolve "interference". Remember - the FCC is the only one with the authority to license use. These are shared channels and we need to share them fairly.
