"buzzing Signal or UVB-76 " ? Interestingly found many radio listeners like to listen this monotonic buzzing signal. Some of them keep on eye to break the code and others just for fun or relaxation even(??). However, nobody knows exactly what is it and what for .This monotone signal consists of a buzzing sound that lasts 1.2 seconds, pausing for 1–1.3 seconds, and repeating 21–34 times per minute. This has slightly changed since its start(1970's ). Some regular listeners have recorded few commands and small conversations. This can be listen on 4625kHZ (AM). This link will show the recording in Wikimedia.
This is a widely spoken topic and many people have researched on this.See the description on the following sites
These two audio clips of the monotonic buzzer were recorded by me on 2018/2/17 at 14:33 and one hour after (15:33). The buzzer is poorly audible ( Need to use headphones) .Reason may be that AM Modulation is poor in contrast to FM and it comes from a long distance .Generally, AM frequency modulation uses to transmit to long distances (mainly not for commercial purposes ) . This Russian radio station in St.Petersbrug transmits signals as shown in the above sites and carry the same tone within 24 hours.
