Welcome to the World of Software Defined Radio (2016)
DVB-T type devices such as the one referred to in this article are indeed remarkably flexible but keep in mind that they are only able to receive. In my case, that quite rapidly exhausted my curiosity.I'm now eagerly awaiting delivery of a LimeSDR (https://www.crowdsupply.com/lime-micro/limesdr), one of several hacker-friendly radio peripherals that can both receive and send (in the LimeSDR's case, in full duplex mode) because of course having a transceiver is a whole different ball-game. GnuRadio can serve as the logic of both receivers and transmitters.Of course depending on country, frequency and transmitted power you may require licences to operate.
