FM Stereo FM stereo will give you the best sound. But FM signals will 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. AM The range for most AM stations is greater than for FM, especially at night. The longer range, however, can cause stations to interfere with each other. AM can pick up noise from things like storms and power lines. Try reducing the treble to reduce this noise if you ever get it. AM Stereo This means the Delco@system can receive C-QUAM@ stereo broadcasts. Many AM stations around the country use C-QUAM@ to produce stereo, though some do not. (C-QUAM' is a registered trademark of Motorola, Inc.) If your Delco@ system get C-QUAM@, your "STEREO" light will can come on when you're receiving it.
