FCC rule zones
| FM zone (§73.205) | California south of the 40th parallel — Zone I-A (§73.205(b)) |
|---|---|
| Mississippi River | Zone I-AFM translators here use the §74.1235(b)(1) table (Zone I-A) |
| Mexican border | 259 km (161 mi) |
| Canadian border | 1,589 km (987 mi) |
- 125 to 320 km from Mexico: FM translators and boosters may exceed 50 W, with the limits of §74.1235(d)(2).
- Within 320 km of Mexico: FM stations follow the 1992 U.S.-Mexico FM Agreement (§73.207(b)(3)).

Sources for this data
- Coordinates, address matching and census geography come from the U.S. Census Bureau Geocoder; FCC market areas and block population from the FCC Area API. Elevation of the ground: FCC terrain data. NAD27 and UTM: the National Geodetic Survey at NOAA (NADCON 5).
- FM zones are set by §73.205. The Mississippi River divides K and W call letters (§73.3550(e)) and the power tables for FM translators (§74.1235(b)). FM stations less than 320 km from Mexico or Canada are governed by the international agreements (§73.207(b)); boosters and translators in that zone have separate limits (§74.1235(d)).
- The borders, the river and zone lines are plotted from simplified public map data, so any site near a line is flagged for confirmation.
