DC to Daylight: A whirlwind tour of the radio spectrum, and why it matters.

Presented at Notacon 10 (2013), April 20, 2013, 3 p.m. (60 minutes).

Why does the AM dial start at 530 kilohertz? What's between it and the FM band? Why was it such a big deal for analog television to stop broadcasting? These questions and more will be answered in this talk. We'll cover the major points of what the spectrum is used for and the history behind, places to find interesting signals, reception equipment, what software defined radio is, and why paying attention to spectrum allocations matter. We'll also see how we can do spectrum recon in the FCC ID and the FCC licensee database to find stuff you want to listen to.
