Yes, the FCC has the authority to grant waivers for minimum distance spacing requirements in the case of a full-power station on the same channel or the first adjacent channel. However, such waivers are typically granted under specific circumstances and require a thorough review of technical and regulatory considerations. The FCC assesses each waiver request on a case-by-case basis to ensure that it serves the public interest and does not cause undue interference to other stations or services.
