Every morning when I wake up, I see a picture. It hangs about 3 feet from my point of view. It's one of mine - I took it some years ago. I look at the picture but I see something different - this is a recurring ritual - I'm nearsighted. I need my glasses - the image is out-of-focus, stylised - a blurry, fuzzy image, like a radio station not properly tuned - a lot of static distortion and blown - with the sound swinging - fading and increasing at the same time - a kind of shortwave reception, perceived and unperceived - waving in space - then I put on my glasses and everything goes back to normal...or that is what I think.
Shortwave radio is radio transmission using shortwave radio frequencies. Shortwave radio is used for broadcasting voice and music to shortwave listeners over very large areas - sometimes entire continents or beyond.
