FCC Rules and Regulations (Part 97 and Related)
What the Extra exam expects
Part 97 is the legal backbone of every license class, but the Extra question pool reaches into subparts that Technician and General candidates rarely touch: §97.101 (good engineering and good amateur practice), §97.113 (prohibited transmissions), §97.115 (third-party traffic), §97.117 (international communications), and the §97.119 station-identification rules. Know that the FCC, not the ARRL, is the governing authority, and that the Commission delegates examination administration to Volunteer Examiner Coordinators under §97.509–§97.527.
Concepts to master
- Control operator duties (§97.103–§97.105): the control operator is responsible for the proper operation of the station at all times, even when the station is remotely controlled. Third-party traffic rules hinge on whether the message is enciphered (prohibited) or merely encoded for a satellite or repeater control function (permitted).
- Prohibited communications (§97.113): no business communications except in narrow exceptions; no broadcasting; no obscene or indecent language; no music except incidental to a rebroadcast or in certain emergency contexts; no communications with stations in countries with which the U.S. does not have a third-party agreement.
- Identification (§97.119): identify at the beginning and end of each communication and every 10 minutes during a contact, using the FCC-assigned call sign.
Traps
The exam loves the distinction between amateur frequencies and the 60-meter band (channelized, 100 W ERP maximum, specific frequencies), and between broadcasting and one-way communications permitted for emergencies, beacons, and telemetry. Another trap: §97.313 power limits - the minimum power necessary, not a fixed ceiling, governs ordinary operation.
Rule of thumb
If a question asks whether a transmission is legal, ask three questions in order: (1) Is it within an authorized band and mode? (2) Is it a prohibited communication type? (3) Is it properly identified? If any answer is "no," the answer is "not permitted."
