HOPE XII: TIME TRAVEL WITH SOFTWARE DEFINED RADIO<\/h2>\n

by: Tom Nardi<\/p>\n

It\u2019s easy to dismiss radio as little more than background noise while we drive. At worst you might even think it\u2019s just another method for advertisers to peddle their wares. But in reality it\u2019s a snapshot of the culture of a particular time and place; a record of what was in the news, what music was popular, what the weather was like, basically what life was like. If it was important enough to be worth the expense and complexity of broadcasting it on the radio, it\u2019s probably worth keeping for future reference.<\/p>\n

But radio is fleeting, a 24\/7 stream of content that\u2019s never exactly the same twice. Yet while we obsessively document music and video, nobody\u2019s bothering to record radio. You can easily hop online and watch a TV show that originally aired 50 years ago, but good luck finding a recording of what your local radio station was broadcasting last week. All that information, that rich tapestry of life, is gone and there\u2019s nothing we can do about it.<\/p>\n

Or can we? At HOPE XII, Thomas Witherspoon gave a talk called \u201cCreating a Radio Time Machine: Software-Defined Radios and Time-Shifted Recordings\u201d, an overview of the work he\u2019s been doing recording and cataloging the broadcast radio spectrum. He demonstrated how anyone can use low cost SDR hardware to record, and later play back, whole chunks of the AM and shortwave bands. Rather than an audio file containing a single radio station, the method he describes allows you to interactively tune in to different stations and explore the airwaves as if it were live.[…]<\/p><\/blockquote>\n
