1040 Hertz is also not a harmonic of anything clock-like, and there's no other signals except at that frequency (nothing that 520 or 2080 Hz)
(((THEY)))'VE BUGGER MY HOUSE AND EXFLITRATING DATA!

Time to triangulate and find the source.
After that you can make suppositions.
Bentley Cruz
Good point, perhaps it's some kind of battery powered remote spycam or something of the like that's scheduled to exfil data at certain times.
good luck user, post results once youve found it.

Guaranteed OP will shamefully abandon the thread once he finds out it was just coil whine or some other bullshit (or he goes off to chase his next conspiracy theory)

Do a binary search: turn off half of all potential sources (consider your housemate's bedroom a source that you don't turn off) and see if the signal reoccurs within the next 40 minutes. If it doesn't, that means the source is among the turned off potential sources, or vice versa. Repeat until only one is left. Results guaranteed in O(log n) if you haven't omitted a potential source.
Robert Stewart
You think that might come from the dongle? Chinks sometimes bug random shit. Turn the amplification on the microphone all the way down and see if you still pick up anything.
Jaxon Hughes
You can do it faster by starting with triangulation to get an approximate location. The precision of triangulation depends on how consistent the signal's strength is and how precise your measurements are.
Jonathan Ramirez
Well the sound IS probably coil whine. It however indicates that something is operating at regular intervals like that. For what you know the coil COULD actually be powering a transmitter.
Thomas Martinez
Going to try different USB dongles today.
fwiw, the above was recorded with a Sound Blaster Play! 3
Leo Richardson
Same signal, different dongle.
(And that's probably a Morse 'L')
