NOTE: Changes as of v5.0.0:

 - PRs will be opened directly against `main` and the `unstable` branch will no longer be used

 - Version tags will be automatically created on each merge to `main`

 - A release will be created on each `major` or `minor` version tag but not `minor` tags

 - Checking out `main` is recommended over using a release artifact to stay on the latest version

 - This repo has significantly diverged from the original project [microtony/RTLSDR-Airband](https://github.com/microtony/RTLSDR-Airband) so it has been been detached (ie no longer a fork).

 - Specific build support for `rpiv1`, `armv7-generic`, and `armv8-generic` have been deprecated for the new default `native`, see [#447](https://github.com/charlie-foxtrot/RTLSDR-Airband/discussions/447)



NOTE: Repo URL has moved to https://github.com/charlie-foxtrot/RTLSDR-Airband see [#342](https://github.com/charlie-foxtrot/RTLSDR-Airband/discussions/342) for info



## Overview



RTLSDR-Airband receives analog radio voice channels and produces

audio streams which can be routed to various outputs, such as online

streaming services like LiveATC.net. Originally the only SDR type

supported by the program was Realtek DVB-T dongle (hence the project's

name). However, thanks to SoapySDR vendor-neutral SDR library, other

radios are now supported as well.



## Documentation



User's manual is now on the [wiki](https://github.com/charlie-foxtrot/RTLSDR-Airband/wiki).
