This is a 10-min recording i made with audacity of the mysterious russian radio signal known as "the buzzer". It can be found by tuning the dial of your shortwave radio to 4625khz. The radio station's call sign is uvb-76.
Static with a sort of jackhammer pace at 107. 9 on the fm side of the radio dial. Recorded from a digital tuner, with a quick flip to 87. 5 fm then back to the 107. 9 static. Definitely qualifies as noise.
Waiting for better signal of hk0na 2012-01-30 at abt 6. 00 gnt in qth jn79ek. Fighting with qrm local and lids on frequency. Sigs were too weak for trying a qso.
