They're flashcards for preppers. The need to knows on how to use ham radios.
PAM Radio stands for "Prepper Amateur Radio." They're flashcards that tell preppers the practical stuff they need to know to use ham radios, primarily the small and inexpensive handheld ones. The cards tell you just the practical stuff, not the complicated details, and are written in understandable language, not technical jargon. They use easy-to-remember examples and provide links to suggested products. PAM Radio is not a test preparation app for taking your FCC amateur radio license test. Instead, PAM Radio is for people who need to know enough about radios to communicate but don't need a new complicated and expensive hobby. Just the practical stuff preppers need to know. The app is free - what do you have to lose?
