FCC rule zones
| FM zone (§73.205) | Zone II (§73.205(c)) |
|---|---|
| Mississippi River | WestNew call signs start with K (§73.3550(e)); FM translators use the §74.1235(b)(2) table |
| Mexican border | 64 km (40 mi) |
| Canadian border | 2,077 km (1,291 mi) |
- Within 125 km of Mexico: FM translators and boosters are limited to 50 W toward the border, with their interfering contour within 32 km and 60 dBu contour within 8.7 km in that direction (§74.1235(d)(1)).
- 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.
