Major / Minor Version Changes:
Changes as of v5.1.0:
- License is now GPLv2 #503
NOTE: Repo URL has moved to https://github.com/rtl-airband/RTLSDR-Airband see #502 for info
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 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
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.
Contributing
Changes are merged through pull requests. Open a pull request from either a branch in
this repository or from your own fork.
Branches in this repository are named <prefix>/<short_description>, where the
prefix is a username or a category such as dev or fix (e.g. dev/drop_macos14_ci,
fix/docker-ci-no-push-on-pr).
VSCode setup is provided, running in the devcontainer installs all dependencies. If
developing locally, install the pre-commit hooks once after
cloning (pre-commit install). NOTE: uv needs to be
installed to run the pre-commit hooks.
