Every question in the three FCC pools, each with a plain-language explanation of why
the answer is right, the rule it comes from, and a study plan that learns what you keep
missing. The exam draws one question from every group, so everything here tracks you
group by group. Pick your element.
Explanations on every question: why the answer is right, why the tempting one is wrong, and something to remember it by.
Mnemonics on most questions: the picture, pun or number trick that makes the fact stick. 100 watts for a beacon, picture 100 slices of bacon.
The rule itself, inline, for every question that cites Part 97.
Study now serves what is due and what you have not seen yet, and brings back what you miss.
Practice exams built like the real one, one question per group, with a readiness estimate.

Questions and answers are the published NCVEC pools, reproduced verbatim. Explanations
are HamSandwich's own. Rule text is the eCFR's.
