RF PREP // ABOUT
Free amateur radio study, without the tracking.
RF PREP is a free study service for the amateur radio community. It presents official pool questions with the correct answer and a key takeaway, intentionally omitting incorrect answer choices.
Privacy
RF PREP itself does not collect or request personal information, set cookies, run behavioral analytics, or accept or serve advertising. Ordinary web-server logs, if maintained by the hosting provider, are outside the RF PREP application.
Study use
RF PREP is an independent study aid and is not affiliated with or endorsed by the FCC or NCVEC. Current FCC rules and official NCVEC question-pool material remain authoritative.
Terms
The service is provided as-is for personal study and community use. No guarantee is made that every explanation is error-free or that study alone will result in passing an examination.
