About SDR Touch - Live radio via USB

SDR Touch allows connecting hardware SDR receivers to Android via a USB cable. Turn any mobile phone or tablet with USB host/OTG support into a portable software defined radio scanner and a spectrum analyser. Driver support exist for RTL-SDR, NeSDR, SDRplay and HackRF.

Listen and record live over-the-air FM stereo radio stations with RDS, weather reports, emergency stations, taxi traffic, airplane communications, audio of analogue TV broadcasts, HAM radio amateurs, digital broadcasts and many more! Depending on hardware used, radio frequency coverage can span from 20 MHz to 2.2 GHz. SDR Touch demodulates broadcast FM, AM, narrowband FM, upper sideband (USB) and lower sideband (LSB) signals.

The built-in RDS monitor will allow exploring the hidden digital data feed that most commercial FM radio stations broadcast. This includes the station's program type (PTY), country of broadcast (ECC), date and time (CT), unique program identifier (PI), list of alternative frequencies (AF) and advanced statistics about the digital RDS carrier signal.

SDR Touch receives live radio via external USB hardware. The app runs offline and does not require a data plan or an internet connection! Take SDR Touch anywhere and find out what hides in the radio spectrum!

In order to run SDR Touch, you will need to plug your SDR receiver into the Android device using an USB OTG cable.
