Though the analog TV system has been switched off, the air waves are not silent. This is What Remains. After the switch off here in Adelaide, the first capital city to do so, I was given an small portable B&W TV. The interesting thing about it is that it tunes like a radio. Turn the dial and sweep the frequencies. I knew there would still be signals such as digital TV but I was very surprised as to what I found. A variety of patterns and sounds. Presented here, in a rythmic form are some of those signals.
