UVB 76 a.k,a the buzzer

UVB 76 also known as the buzzer or mdzhb is a russian confirmed military station that has been brodcasting since atleast 1973 oldest recording is from 1976.

It brodcasts a short buzz that lasts about 1 second however before 1989 the buzzer sounded like a pip however in 1989 the station sound changed this could be due to the machine being well... old many theories have been made that the sound was generated from a old ww2 box.However this isnt the case.In 2010 the station moved to another location.The station sometimes brodcasts code which we cannot translate because there is no way to decode it,its russian military code.The buzzer has brodcasted music many times however this can be because there might be radio or tv in the room with the buzzing machine.
