For the lazy who were hoping to find an audio clip in the article: you can find some here: http://www.sigidwiki.com/wiki/The_Buzzer_(ZhUOZ_MDZhB_UZB76)
Any speculation that it's as mundane as a test tone for a specific radio device? Is your radio working, is it calibrated properly...
I read this article last weekend and after reading it, I put batteries in my shortwave radio to see what was out there. Turns out, there's pretty much nothing. I couldn't hear anything on 4625 kHz. I let my receiver scan and when it was done I checked out what it detected and found absolutely nothing interesting. The most powerful signals were Christian broadcasts that had a kind of doomsday feeling about them. It se…
Night hours are best for shortwave reception. You could also need an external antenna depending on how far you are listening from. Another problem, probably the biggest one today, which affects reception on these frequencies (and generally on the HF bands) is the radio noise generated by many bad designed switching power supplies and appliances. Switching regulators (power supplies, converters, chargers etc.) for eff…
The shortwave frequencies still feel very underutilized. When I scan the FM (88 - 108 MHz) and AM (540-1600 kHz) radio frequencies, I pick up a lot of stuff. The shortwave band is relatively vast and feels very sparse. Considering how valuable spectrum is these days, it's hard to believe that we couldn't find a better use for it. Is it because it is so prone to noise that it's less valuable?

Were you in a good spot? I can hear a lot of stuff with my shortwave receiver and I'm in SLC, Utah. Occasionally, I get to hear pirate transmissions and whatnot.
I pick up a lot on the FM and AM bands. The shortwave bands feel comparatively empty.

This reminds me of a numbers station. https://en.wikipedia.org/wiki/Numbers_station
