via HACKADAY: Ask Hackaday: Is Shortwave on Life Support?

Between World War II and Y2K, shortwave listening was quite an education. With a simple receiver, you could listen to the world. Some of it, of course, was entertainment, and much of it was propaganda of one sort or another. But you could learn a lot. Kids with shortwave radios always did great in geography. Getting the news from a different perspective is often illuminating, too. Learning about other cultures and people in such a direct way is priceless. Getting a QSL card in the mail from a faraway land seemed very exciting back then.

Today, the shortwave landscape is a mere shadow of itself. According to a Wikipedia page, there are 235 active shortwave broadcasters from a list of 414, so nearly half are defunct. Not only are there many “dead” shortwave outlets, but many of the ones that are left are either not aimed at the world market or serve a niche group of listeners.

You can argue that with the Internet, you don’t need radio, and that’s probably correct in some ways but misses a few important points. Indeed, many broadcasters still exist as streaming stations or a mix of radio and streaming. I have to admit I listen to the BBC often but rarely on the air. My computer or phone plays it in crystal clarity 24 hours a day.
