How do radio stations work at night?
As it turns out, the ionosphere reflects certain frequencies of radio waves. So the waves bounce between the ground and the ionosphere and make their way around the planet. You can pick up some radio stations better at night because the reflection characteristics of the ionosphere are better at night.
Do radio stations play music all night?
Many radio stations are automated nights and overnights. Many years ago most stations staffed 24 hours a day, but due to cutting costs, those positions have been eliminated. Voice tracking is used by some stations; others just play music overnight with minimum interruptions. Automation is not new.
How many employees work at a radio station?

Is it safe to leave radio on all night?
Dear Gatete, Sleeping with the radio on is not a very good idea. Radiation waves, however small, are emitted from a radio set as well. Moreover, if the radio plays all night, you may fall asleep due to being exhausted and or the body being conditioned to that sound.
Is listening to radio while sleeping bad?
It’s fine to fall asleep listening to music, Breus says, but don’t wear earbuds or headphones to bed. They can be uncomfortable, and if you roll over wearing earbuds, you could hurt your ear canal.
What do you call someone who works at a radio station?
A radio personality (American English) or radio presenter (British English) is a person who has an on-air position in radio broadcasting. Broadcast radio personalities may include talk radio hosts, AM/FM radio show hosts, and satellite radio program hosts.
Why do AM radio stations have to turn off at night?
Most AM radio stations are required by the FCC’s rules to reduce their power or cease operating at night in order to avoid interference to other AM stations. FCC rules governing the daytime and nighttime operation of AM radio stations are a consequence of the laws of physics.
How do AM and FM radio stations work?
AM and FM radio stations work by sending out shows via radio towers. Listeners that have receivers in their car or at home can tune in. Not many people know this, but AM and FM stand for: AM = Amplitude Modulation. FM = Frequency Modulation.
Why do AM radio waves travel better at night?
Because of the way in which the relatively long wavelengths (see Footnote 1) of AM radio signals interact with the ionized layers of the ionosphere miles above the earth’s surface, the propagation of AM radio waves changes drastically from daytime to nighttime.
What license do radio stations need to play your music?
So, American songwriters and publishers can register their works either with ASCAP, BMI, SESAC or Soundexchange which means that a radio station that wants a license to play any music they want must get a license from all four PROs.
