The device is a DAB/FM/SDR peripheral that is used to tune TV in other countries. They're cheap $12 tuners that allow a computer, in this case a phone running Android, here a moto X, to receive radio frequencies from around 54 MHz up to around 1.7 GHz. The picture with the airplane is my phone decoding an ADS-B stream, which is a signal broadcast by most airplanes at 1090 MHz, giving their location, speed, heading, flight number, etc, using the app "ADS-B On Android Pro". The other picture with the spectrum, is " RF Analyzer " and it is showing a local FM radio broadcast station. These little dongles will give nerds and the curious nearly unlimited entertainment, learning about all the radio waves that fly through us every day.
