New Raspberry PI Complete OS release

[Glen I Langston]

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.

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.

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   Maybe just before 3.8 is obsolete I’ll catch up.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
