About this app

Radwave makes it possible to interactively explore full resolution RF spectrum. You can look through massive datasets served from the cloud using just your phone or tablet, or use an RTL-SDR dongle and the RTL2832U driver app to collect data locally on your device and interactively explore in real time.
You can dynamically zoom in and out in time and frequency, pause, and go back in time - all without losing any samples. If you find something cool, tag it and share with friends.

Radwave’s cloud based datasets currently include data from Breakthrough Listen, including data from Voyager 1 and ‘Oumuamua. Radwave’s core technology provides low latency1 access to full resolution spectrograms created from the raw GUPPI files. By using intuitive pan/zoom gestures, you can easily explore the full resolution spectrum, manipulating time, frequency and power colorization dynamically. Coming soon are datasets collected from Radwave HQ for FM radio and NOAA weather satellites.

Radwave core technology is its interactive real-time spectrogram/waterfall plot. It shows the entire spectrum - utilizing every sample2 - for the entire collection3. Frequencies are aligned over time as you change the RF center frequency4, helping you make sense of what you see.

Please note that Radwave does *NOT* currently support audio demodulation. This functionality is planned for a future release, but is not in the current version.

1 Cloud based datasets are currently hosted in AWS US East 1, so latency may vary geographically

2 Adjacent non-overlapping DFT windows

3 Up to device limitations

4 Alignment limited by buffer uncertainty

We're in beta!

We're launching in beta as a crowd funding method, but without you having to wait to have something usable. We'll be continuing to add features and functionality. Email us at support@radwave.com or contact us on Twitter at @RadwaveRF and let us know what you want to see so that we can prioritize our time.

This app is definitely great (and the fact that it lets me switch apps to work on other stuff while it still runs is also great), but it would be way better with demodulation and the ability to actually listen to the signals being picked up from the app real-time like some other apps do (which I know might come in a future update).

Thanks! Audio demods are in the works!

My boss just shared this to his Facebook and when I watch the video posted in twitter and was streamed in Youtube, this blew my mind like how?? This is so incredible! I cannot fathom the idea of such a massive amount of data can be transformed into this! I'll definitely share this to my friends!

I know processing all this data takes time but it would be nice to have a little chunk for free to get a feel for things and see if it's worth the 10 bucks

I'm working to see what's doable on money. For free you can use Radwave with a RTL-SDR. The Breakthrough Listen data is free and each Radwave collection has links to the data that was used. In Radwave v0.5.4 I added links to blog posts about it. So you can to download and process the raw data. But for $10, you can see it now and help fund more.

What's new

Now including Breakthrough Listen! Explore the spectrum to find Voyager 1 transmissions, and compare 'Oumuamua ON/OFF observations! More cloud based datasets coming soon.

Interactive power spectral density plot to control spectrogram colors!

Bug fix for controlling gain with remote rtl_tcp instance and other settings fixes.
