About this app

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!

Disclaimer: Keep in mind that SDR Touch is under development and it could be unstable. Also make sure you agree with the Terms and Conditions in SDR Touch and fully understand that it might against the law to listen to some non-standard radio frequencies in some countries. I am not liable for any damages caused by improper usage of SDR Touch and SDR Touch Key!

Still the killer mobile SDR app. While there are some free waterfall-driven apps, this was one of the first, and is still the easiest to use, with menus that have obvious controls that get out of the way when you want them to. Setting, scanning, exporting and importing memory channels is a breeze. I bought the SDR Touch Key one time ages ago and any Android device I'm signed into my Google account with has never had any trouble using the pro features.

Not bad. But navigation is clunky, can only see 1MHz wide or less on the screen. No real support documents. Impossible to do tasks such as wideband scans between 474-800MHz for example, would take hours. Need to provide display options for much wider bandwidth, with variable scan resolution..

RDS demo worked before upgrading, now does not, only visible when FM broadcast is selected, but NFM sounds much clearer, but no RDS option, in contrast a free version of RF analyzer sounds much beter but lacks RDS option. Was surprised to see 162.4 would not tune in, but 0 issue in analyzer app. Tried a multitude of settings, finally got it but doesn't sound as nearly as clean as other app. Not trashing, but free working much better then paid?
