So I bought a radio and for some days I have been noticing that a channel with static frequency at somewhere around 880 KHz Is tuning properly during day time but at night, the channel can be heard for a wide range of frequency, I mean , at night , the channels static frequency seems to be mixed up and the channels static frequency changes into a ranged frequency . That can be heard from almost 560KHz to 1000KHz (while 880KHz is the absolute and provides better sound quality).
I am using the radio in AM mode. This phenomenon usually happens at night.
Now my question is, what makes this phenomenon happen?
I hope my new radio isn't faulty
