About this app

Software Defined Radio using an RTL-SDR dongle or a remote instance of rtl_tcp.

This application is about having a bit of fun with those amazing little RTL-SDR dongles, whilst listening to AM/FM/SSB radio signals. It's nice and easy to use so why not give it a try?

- Covers the full frequency range of your RTL-SDR dongle.
- AM and FM, wide and narrow, SSB
- FFT and Waterfall displays.
- Sample rates 240000 Hz to 2160000 Hz.
- Bias tee control.
- 75 presets over 5 pages.
- Gain controls.
- Squelch.
- Flexible display options, hide things you don't need to see.
- Built-in help.

There are two ways to use the application. The first is to use an RTL-SDR dongle and an SDR driver, available from Google Play. Selecting the Driver option in the application menu will open the driver page on Google Play. The second way is to connect to an instance of rtl_tcp running on a remote computer, most likely over WiFi. You will need a good network connection for this to work reliably so use of the driver is probably the preferred way to use the application in most cases.

We hope you enjoy using this application.
