You can move an LPFM station more than 11.2 kilometers (approximately 7 miles) away under specific circumstances outlined by the FCC. Here are the scenarios in which such a move is allowed:
Contour Overlap: If you plan to relocate the LPFM station to a new location that is more than 11.2 kilometers from its current site, you must conduct a contour study. This study should demonstrate that there is a 60 dBu contour overlap between the LPFM station's current service contour and the proposed service contour at the new location. If the overlap requirement is met, you can proceed with the relocation.
Time-Sharing Agreement: LPFM stations that are currently operating under a time-sharing agreement with another LPFM station may move more than 11.2 kilometers in order to place both stations on the same tower or in proximity to each other.
Short Spacing to Third-Adjacent Channel: If your LPFM station is currently "short-spaced" to a third-adjacent channel FM station, you may relocate to a new location that is within 500 meters of the third-adjacent channel station's transmitter.
It's important to note that even when moving more than 11.2 kilometers away, you must ensure that the new location complies with all minimum distance separation requirements as specified in §73.807 of the FCC rules. If your current location is short-spaced to a subsequently filed broadcast station and the new location remains short-spaced, the FCC may only approve the move if it results in an increased distance between your station and the other station to alleviate interference concerns.
To move an LPFM station more than 11.2 kilometers away outside of a major change filing window, it is indeed required to provide a contour study demonstrating that the 60 dBu protected contour of the current facility overlaps with the 60 dBu protected contour of the proposed facility, even if this overlap is minimal.
Furthermore, it's important to note that waivers for such moves are no longer granted. This means that LPFM stations must adhere to the specified contour study requirements and cannot request waivers as a means to bypass these requirements.
Compliance with these regulations is crucial when planning a move of more than 11.2 kilometers for an LPFM station.
In summary, moving an LPFM station more than 11.2 kilometers away from its current location is permissible under specific conditions related to contour overlap, time-sharing agreements, and short spacing to third-adjacent channel stations. However, compliance with FCC rules and regulations is essential throughout the relocation process.
