Guys,

Thanks for your replies so far.
The buzz/noise is irregular. Not always, and when it's there, it's not
always audible on the same frequencies.
I am afraid it's something in the neighbourhood. Lots of houses around,
so it probably won't be easy to find out exactly where it comes from.
I also hear it when I connect a simple wire as an antenna, so I think
it's not a ground loop?
I made a recording of 1602 kHz. this afternoon. You can hear the
buzz/noise there, although not as strong as previous times.
Maybe someone can tell more by listening to the audioclip?
It is at http://mark-veldhuis.nl/1602.mp3 .
