United States of America

50 kW stations (not all of these are 50,000 watts daytime and nighttime) - this is a work in progress and may be transferred over to its own page at some point or another.

The following is a list of radio stations in the United States that are authorized to run 50 kW (50,000 watts) of power. This is the highest power authorized to any AM station in the United States.

Power Legend: U=unlimited time, D=daytime power, N=nighttime power, CH=critical hours power. Class A unless otherwise specified. Omnidirectional antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system. DA means the station uses a directional antenna system. DA1 means the pattern is always directional, with the same pattern, day and night. DA2 means the station has two different patterns (protecting different stations), one for Day, and one for Night. DAN means the station broadcasts omnidirectionally (equal in all directions) Day, and directionally at Night.
