The neighborhoods of North Shirley, Shirley Center, and Woodsville in the town of Shirley, Massachusetts. Maximum range is 2 miles, but more is possible using good DX equipment or car radio. (AM range is during daylight hours only in locations AWAY from power lines. See map below.) During the most ideal conditions (daytime - morning - winter - dry weather), the AM signal can be received on a high quality car radio at "hot spot" locations over three miles away.

Do you only hear the strongest AM stations on your car radio and the rest is noise? Chances are your antenna connection is faulty or corroded.  If your vehicle is still under warranty, your dealer will repair the problem free of charge.
