KPFK contended that areas in Los Angeles and Orange counties areas such as Malibu, Long Beach and Costa Mesa are within the protectedtheir protected class B areas for KPFK and suffered significant interference from XLNC.
The FCC does not look at situations such as you describe, where a local or semi-local has blockage and a different station with no blockage locks your radio. Malibu and Long Beach are blocked. And Costa Mesa is outside the protected contour of a conforming B from Mt Wilson. There are thousands of cases of where, inside a station's 54 dbu protected contour some other station comes in better due to terrain.
The FCC can not require mountains to move nor can it change the nature of propagation.
That is why XLNC had to move inthe first place.
Victor Diaz had been working on the upgrade of XHLNC for years; he even endowed the station in his will. They did not have to mover, as the assignment was technically valid since it did not overlap the protected contour of KPFK as a fully compliant B.
If 90.7 is open to Tijuana applicants, then so should be 93.1, 95.5, 101.1 and all the other Mt. Wilson big sticks.
The frequenies you mention can not be used due to spacing against co-channels, adjacents and next adjacents. For example, 93.3 is a first adjacent to KHTS in San Diego, and can not be used. 95.5 can not be used as it is next to KUSS in SD at 95.7.
Do your homework before you make blanket statements that have no truth.
This of course would benefit holders of other Mt. Wilson signals that are not so strong, such as Univision Radio, and may explain certain posts here...
That explains nothing. FMs on Wilson, despite all being "Super" B's, are only protected to the 54 dbu contour of a conforming B.... For example, KLVE used to be Top 10 in the Santa Barbara market but the FCC licensed a new station at 107.7 and now you can not hear KLVE there. There were no grounds for protest, as that coverage area was not guaranteed... just the standard B contour.
And that is what happened to KPFK. They lost some unprotected coverage, and there was nothing to do about it.
