The following factors can be considered as possible
causes of noise appearing at night.1. Factors due to signal conditions: Due to the
fact that long-distance signals are more easily
received at night, even stations that are received
without problem during the day may experience
interference in a general worsening of reception
conditions. The weaker a station is the more
susceptible it is to interference, and a changeto a different station or the appearance of a
beating sound* may occur.
Beat sound*: Two signals close in frequency
interfere with each other, creating a repetitious
high-pitched sound. This sound is generated
not only by sound signals but by electrical waves
as well.
2.Factors due to vehicle noise: Generator noisemay be a cause.
