Get the red carpet treatment for your SDR experience! Unlock the full potential of your Android device and use the pro features of SDR Touch. You will get:

 - Spectrum Analyser - See 1 MHz of the spectrum real time on your screen. Identify potential signals of interest visually.
 - Advanced RDS Monitor - Explore the digital RDS data feed that is broadcast with FM radio stations. See PI, AF, CT, PTY, ECC, signal quality, constellation display and RDS group statistics.
 - Audio Recording - Record your favourite tunes in STEREO straight from the radio or tape that random chatter you randomly came across on the HAM band - it's up to you!

How does it work:
You need to have SDR Touch already installed on your Android powered device. Purchase and install SDR Touch Key. Next time you start SDR Touch you will be able to use the pro tools and the "DEMO MODE" will have disappeared!

If you have not tried SDR Touch yet, I highly recommend installing it first to check whether it is compatible with your USB dongle, phone or tablet.

Please don't purchase if your Android device or USB dongle is not compatible with SDR Touch!
