Greetings,

Which satellite is this? It seemingly transmits only a constant buzz: http://gabucino.hu/tmp/SDRSharp_20141129_224829Z_465981kHz_AF.mp3

As to identifying its position, once it went under the horizon at 2014.11.25 17:33 CET, as evidenced below: http://gabucino.hu/tmp/466sat.jpg

Interestingly, sometimes two satellites can be seen after each other: http://gabucino.hu/tmp/2sat.png
