This video clip is of the HDSDR application using one of the little SDR USB receivers. Pretty amazing technology for a USB device that cost around $20. Takes a bit of time to get all the software installed and configured on the computer, but it's pretty neat once you get it up and running.
Here is a website you can check out for more information on these little receivers.
And here is the site for the HDSDR software.
