This radio is located in Enschede, Netherlands, at the University of Twente. It is a Software-Defined Radio (SDR) and hooks up to a computer. It has no knobs, just an on/off switch. The radio converts analog signals
into digital signals, ones and zeros, something a computer can deal with. If you Google SDR Radios you can find other SDR radios that are connected to the Internet such as those on the Kiwi SDR Map
