AMSAT-NA has a free “Getting Started” compendium available for download. AMSAT-NA tells us:
Here is a freely downloadable compendium of “getting started” articles written by Keith Baker, KB1SF/VA3KSF. These articles originally appeared in The AMSAT Journal from 2019 to 2021.
Unfortunately, because both satellites and URLs change over time, the currentness of information such as this can quickly be overcome by events. However, the tools and techniques outlined in Keith’s beginner series are still very much applicable to operating on current and future AMSAT satellites.
