The longer range, however, cancause stations to interfere with each other. AM can pickup noise from things like storms and power lines. Tryreducing the treble to reduce this noise.FM StereoFM stereo will give you the best sound, but FM signalswill reach only about 10 to 40 miles (16 to 65 km).Tall buildings or hills can interfere with FM signals,causing the sound to come and go.3-96
