How to Enjoy FM Stereo

1. Select Stations Within Range - The best FM fidelity will be obtained from stations within a 16-64 km (10-40 mile) range. Beyond that noise or flutter may begin to appear due to the line of sight range limitations of FM signals. Solution:
Reduce treble response by reducing the treble control in fringe areas.
2. Realize Tall Structures Can Interfere - Tall buildings or hills may cause shadows or cancellation of FM signals (this is similar to the ghost or flutter effect seen on television sometimes when airplanes are flying in the vicinity). It will sound like a pop or momentary hiss. Solution:
Reduce the treble control.
3. Interference from Another Station - Although the circuits in Delco receivers are the most advanced available, there are rare instances where a station being listened to will be interfered with by another station. This only happens when the stations are on almost the same frequency and certain geographical criteria are present. Solution:
Select another station or switch to tape.
