Oftentimes, when an FM radio signal bounces off a building or mountain, it will change frequency and create a "ghost station". If you tune around the dial slowly, you might notice a faint station that when tuned a bit more will fade, then come in really clearly. It's possible you might be tuned to a ghost band if the tuner is analog (using a wheel rather than pressing buttons). Otherwise, if you see a little black or white wire coming from the back of the radio, find a way to tack this to the wall vertically - the straighter and higher, the better. This is a cheap external FM antenna that is often built into clock radios.
