Have you ever wondered what’s in the radio waves zipping\u00a0invisibly around you every day? \u00a0Software-defined radio\u00a0(SDR)<\/a>\u00a0is a great\u00a0tool to explore radio signals using a computer and inexpensive radio tuner. \u00a0With SDR you can examime many\u00a0radio signals such as FM radio<\/a>, television<\/a>, emergency & weather radio<\/a>, citizen band (CB)<\/a>, and much more<\/a>.<\/p>\n

Although dedicated\u00a0SDR hardware like the HackRF<\/a>\u00a0allow you to tune\u00a0an immense range of the radio spectrum, you can easily get started with SDR using a Raspberry Pi and\u00a0inexpensive RTL-SDR tuner<\/a>. \u00a0Inspired by the HackRF PortaPack<\/a>, this project will show you how to build\u00a0a small portable\u00a0SDR scanner using a Raspberry Pi, PiTFT<\/a>, and RTL-SDR<\/a>\u00a0radio dongle. \u00a0With the Raspberry Pi Freq Show RTL-SDR scanner you can visualize the invisible world of radio!<\/p>\n
