What Can I Pick Up?

AM/FM radio stations you should be able to receive at your location

Reception threshold

Daytime AM power

AM stations often reduce power (or go off air) at night to protect other stations on the same frequency.

Simplified model: free-space + line-of-sight for FM, ITU-R P.368 groundwave (assumed average ground conductivity, not your actual local terrain) for AM. Real reception varies with terrain, buildings, receiver quality, and weather.
