Fun with the Funcube Dongle

UVB-76I was playing with my Funcube Dongle last Saturday testing Gqrx for the long awaited 2.0 release. I was using the Funcube Dongle together with the shortwave converter I got some time ago and a 5 meter long wire attached via an antenna tuner. Amongst all the traffic there is on shortwaves I recorded these two transmissions: UVB-76 aka. The Buzzer, and whistle like signal believed to be a radar in Israel.

Note that I didn’t have the converter calibrated so my frequency readout is 10-15 kHz off.

As I wrote in the video description, it is section 2.8 in this PDF file that led me to believe it is radar. Otherwise, it sounds like someone is testing an AM transmitter with suppressed lower side band. I don’t know if the signal is still there – I haven’t had a chance to listen since Saturday.
