Features & Capabilities

This application is about having a bit of fun with those amazing little RTL-SDR dongles, whilst listening to AM/FM/SSB/CW 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, CW.
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.

The application needs to be connected 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 when using the higher sample rates.

It can be installed on an iPhone, iPad or Apple Silicon Mac.

We hope you enjoy using this application.

This app has excellent support and superior sound quality. I use it to listen ATC. I've gone through a few and this is my favorite. The developer is very responsive at supporting the app. You'll definitely want to get this app. This review is not sponsored. I really like it. Thank you for this wonderful app.
