Sometimes, I wonder what it's like to work in quality control at a shortwave radio factory in China. I imagine the conversation with a new employee could go something like this:
Employee 1: "When I tune through the shortwave bands, all I can hear is loud orchestral music."
Employee 2: "That means it's working."
Employee 1: "But where does it come from? And why is it the same on so many frequencies?"
Employee 2: "Just put the QC PASS sticker on the radio, and wrap the package!"
