This train took me home, let's hear the announcement and the incoming train.

Just recorded my Xbox 360 from 2008 starting up and shutting down.

Very strange sounds from a very high frequency.

A data transmission sound or something recorded from 14664.8 kHz. It's probably a weather transmission.

A radio transmission recorded from 15205 kHz ARS BSKSA Holy Quran Radio in Saudi Arabia.

Another sound recording from 4625 kHz. It's a russian radio signal called "The Buzzer".

Sounds like it was a morse code sent by a human.
