Every party therefore blocks, or excludes, the others from getting on the air.
There is currently no efficient or predictable process for resolving MXs, which are fairly common because in the US we have a limited supply of frequencies, a large demand, and rules which effectively prohibit stations with very small coverages which would be great for many communities. Demand has increased as our population has grown and lately due to the Telecommunications Act of 1996 which allows one entity to own massive numbers of radio stations. From this page you can locate MXs by owner or by state . Another cool resource is Elliott's FCC FM Database Search with whom I have no affiliation. We are currently embroiled in two MX situations.
