Police Scanner: Equipment Autopsy #68

http://thegeekgroup.org/ - We explore the worlds of analog and digital radio as Chris opens up two different types of scanners. First is an old police scanner, which it tuned up by use of quartz crystal. It's followed by a more modern hand radio, which has made the switch to a completely digital setup. Watch to learn about the difference between analog and digital circuits, noise gates, a little about light polarization, and more!
