SDR Projects That Actually Work

Right now, thousands of signals are passing through the walls of your home. Airliners are broadcasting their exact positions from 200 miles away. A weather satellite is photographing your town from orbit and sending the image down - for free. Ships in distant harbors, fire crews across your city, even your neighbor's weather station are all talking on the radio. The only question is: do you know how to listen?
SDR Projects That Actually Work hands you 33 hands-on builds that turn a $35 RTL-SDR dongle into the most capable receiver you will ever own. No dry theory. No parts-bin scavenger hunts. Just weekend projects with real payoffs:

• Track aircraft live on a map with your own ADS-B station - planes, callsigns, altitudes, feeding flight networks worldwide
• Download actual satellite photographs from NOAA weather satellites passing overhead, with the famous DIY QFH antenna build
• Decode your neighborhood - weather stations, tire pressure sensors, garage remotes, utility meters, and pager networks
• Map ships at sea with AIS, crack digital voice on trunked radio, and chase mystery signals across the spectrum
• Build antennas that outperform store-bought - coax collinear, discone, turnstile, tape-measure Yagi - for under $25 each
• Go further with the HackRF One: test signals, FM beacons, and legal transmitting fundamentals done right
