Fresh hacks every day
In case the Realtek RTL2832u-based USB TV tuner dongle isn’t useful enough, the folks behind a project to get a software defined GPS receiver off the ground successfully plotted GPS data in real-time with this very inexpensive radio.
Previously, we’ve seen these dongles grab data from GPS satellites - useful if you’re building a GPS-based clock – but this build … Read the rest

[regveg] was looking for a way to receive signals outside the normal 64-1700MHz range his TV tuner software defined radio dongle can get. After finding a few $100+ upconverters on the Internet, he stumbled across a DIY project that greatly expands the frequencies his RTLSDR can receive.
[George]‘s upconverter uses heterodyning to increase the frequencies received by a SDR dongle. … Read the rest
