Hello We’ve been successful in simultaneous radio astronomy with high schools in the US, including California, North Carolina, Illinois, Virginia, New York and West Virginia.
We’d like to expand to southern hemisphere as well, so that we can get a full sky image of the Milky Way. We’ve just released a new version of the complete Radio Astronomy Operating system for Raspberry Pi 4 computers. The whole 12 GB Os is compressed to 3.4 GB for download. https://drive.google.com/file/d/1PwjSfVUlV4XNyaDtzrgMiI4Z7IL6HGi2/view?usp=sharing The installation guide has the link to the OS as well. All are on Google Drive https://docs.google.com/document/d/1pStZsguO3UMrP0FhxJJJPFYdkg-Bp8TG3_zIh8MYHUQ/edit?usp=sharing The newest version automatically puts all observations on the included Apache web server for sharing with other high schools/hobbyists. FYI you can measure the effective noise temperature of your first LNA using the software included in the OS and described in LightWork Memo 28. https://drive.google.com/file/d/1T6y3XJ9PyVhMCDVL0gaL-mx1BI6bUyEN/view?usp=sharing I’m still stuck at GNURadio 3.13.7.5, but have a few C++ programs converted to 3.8 and running. Maybe just before 3.8 is obsolete I’ll catch up. Best regards Glen
