Jobs in radio arts, from serviceman to station engineer, are easier to get if one has a recommendation of the U.S. Government in the form of a license from the Federal Communications Commission (FCC). This study guide for FCC radiotelephone licenses is designed to thoroughly prepare the applicant for any radiotelephone exam and to serve as a practical reference and guide in the various professions. It provides theory and applications as well as completed detailed answers to questions on any subject an applicant may be asked when taking an exam, complete sets of questions on each element of study, and numerous practical examples. All commercial radiotelephone operator classes are covered--third, second, and first--plus the elements required for broadcast and radar endorsements. The privileges afforded by each class of license and the exam elements which must be passed to get that license are also described. The contents include basic law, broadcast practices, several detailed sections on both basic and advanced radiotelephone, radar endorsement, and extracts from FCC rules. Also included are late amendments to FCC rules, a list of FCC field engineering offices, and answers to sample questions. (Author/SH)
