The Air Horn (a nickname given by radio listeners) is a shortwave radio station that broadcasts on the frequency 4930 kHz. It broadcasts short, repeated Air Horn sounds at a rate of around 60 sigmal per minute, for 24 hours per day. The signal is commonly interrupted by test calls, test counts, equipment calls and rarely voice messages in Russian. The Air Horn has been active since 2017, when its symbolic signal sound was first recorded by listeners, and is probably a sister station to The Alarm.
