I am having a lot of fun with my receiving setup and thought this might be of interest. You can go to the SATNOGS Network site and listen to or download audio and SDR waterfall recordings from the various groundstations. https://network.satnogs.org/

They have a number of ground station projects users can build and interface to the SATNOGS observation network. I am starting out with a simple station that consists of a Raspberry Pi, SDR Dongle, and stationary antenna. Mine will be a turnstile to start. They also have projects for a AZ-EL rotor that uses some 3D printed parts. Some antennas as well.

Once you are setup you log onto the site and schedule your observations. It sends the info back to the Pi with pass times, frequency,mode doppler ect. The pi records the pass and sends the audio and water fall plus any data back to the web site. It even will display some data and WX satellite pictures decoded.

Here are some links to the SATNOGS sites. Their are a lot of Wiki pages and some forums
