      *b	FM (Monaural)
      *c	AM

3. Radio reception problems

   HINT: 

   In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.

   1. Phasing

      AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter.

      TEXT IN ILLUSTRATION
      
      

      *a	Phasing
      *b	Ionosphere

   2. Multipath

      Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter.

      TEXT IN ILLUSTRATION
      
      

      *a

      Multipath

   3. Fade out

      Fade out is caused by objects (buildings, mountains and other such large obstacles) that deflect away part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are less likely to deflect.

4. Noise problem

   Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems.

   Radio Frequency	Noise Occurrence Condition	Presumable Cause
   AM	Noise occurs in a specific area	Foreign noise
   	Noise occurs when listening to an intermittent broadcast	An identical program transmitted from multiple towers can cause noise where the signals overlap
   	Noise occurs only at night	Signal phasing
   FM	Noise occurs while driving in a specified area	Multipath resulting from a change in FM frequency
