RTLSDR-Airband

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 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

NOTE: Repo URL has moved to https://github.com/charlie-foxtrot/RTLSDR-Airband see #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.
