[RFI] RFI Source

[K9MA]

I have what appears to be  very strange RFI source: it's very broadband, 
covering at least the whole 20m band, but it's somehow modulated at 1100 
Hz. In AM mode, the 1100 Hz tone is audible and it, as well as the 
second harmonic show up in the audio spectrum. The tones are present 
wherever the radio is tuned on 20 meters. It's as if a broadband noise 
source is modulated at 1100 Hz. I have heard the tone shift frequency. 
Not a solar system, as it's present at night. Any idea what this could be?

73,
