Talk:Buzzing
From Signal Identification Wiki
This is: HF trading link '350 Hz idle tone' but what that actually is has not been fully confirmed. It's believed to be HFHigh Frequency (3-30 MHz) trading related station, but radar has also been suggested. The picture is good and I will add it to the aforementioned article if it's OK.
