FM Preliminary Study

The FM Preliminary Study uses the FM Query to generate a list of stations, applications, allotments, and petitions for rulemaking that WILL be considered during review of an FM construction permit application. This analysis is based only on spacing considerations (separation between stations); no contour or coverage analysis is performed. As the spacings in this search are set to exceed the maximum spacing requirements in 47 CFR Section 73.207, many records shown on the list may not adversely impact a particular station proposal. The FM Preliminary Study displays records on the same channel or frequency (cochannel), the first-adjacent, second-adjacent, and third-adjacent channels above and below the selected channel, as well as the Intermediate Frequency (I.F.) channels (53 or 54 channels above or below the selected channel).

Please be aware that compliance with the spacing rules may not be sufficient for acceptance or grant of a construction permit application or a petition for rulemaking to add a new commercial FM allotment. The Commission will consider (as needed) additional information which may not be shown here. Because information in the Commission's databases changes daily, as does the FM Query, we cannot guarantee the accuracy of the results obtained from the FM Preliminary Study. Parties interested in Low Power FM (LPFM) stations should use the LPFM Channel Finder which is tailored for that particular service.
