We have updated the ADS-B (dump1090) software for compatibility with the RSP1A. The software now supports RSP1, RSP1A and RSP2/RSP2pro. It can be either downloaded from our Downloads page (for Windows, Linux and Raspberry Pi) – http://www.sdrplay.com/downloads  or the source code can be built from our GitHub repository ( https://github.com/SDRplay/dump1090 ). The user guide has also been updated on the Downloads page and can be seen here: http://www.sdrplay.com/docs/SDRplay_ADS-B_User_Guide.pdf
