HiDef Radio 1.0-beta1 (build 5)

First public test build of HiDef Radio.

You need an RTL-SDR USB dongle, a USB-OTG adapter and a 64-bit Android phone with Android 8 or newer.

Two ways to get it

1. The closed test on Google Play. This is the way that helps most. Google asks for 12 testers over 14 days before the app can be published, and only installs from Play count.

1. Join the group: https://groups.google.com/g/hidef-radio-testers
2. Become a tester: https://play.google.com/apps/testing/io.github.derek20la.hidefradio
3. Install from the Play Store link on that page.

2. The APK below. Download HiDefRadio-1.0-beta1-build5.apk, open it on the phone and allow the install.

Please pick one and stay with it. The Play version is signed with Google's key and this APK with my own, so Android treats them as two different apps. To move from one to the other you have to uninstall first, and favorites are not carried over.

What it does

• HD Radio on FM, with the extra HD2 / HD3 / HD4 programs
• Analog FM in stereo, with RDS (station name, song title and artist)
• A blend between analog and HD like a car radio: sound at once, HD about ten seconds later, and back to analog before a dropout
• HD Radio on AM (digital only, and little tested so far)
• Favorites with station logos, media controls on the lock screen, signal details for radio people
• No internet permission, no ads, no tracking

Known limits

• Developed with an RTL-SDR Blog V4. Other dongles should work on FM but are not confirmed yet.
• Tested in the Los Angeles area only, on two phones.
• AM is HD only. Analog AM is planned for 1.1.
