Last I knew a "General" class FCC radiotelephone license (GROL) is still required to do CB radio repairs.
§ 95.424 (CB Rule 24) How do I have my CB station transmitter serviced? (a) You may adjust an antenna to your CB transmitter and you may make radio checks. (A radio check means a one way transmission for a short time in order to test the trans-mitter.) (b) You are responsible for the proper operation of the station at all times and are expected to provide for obser-vations, servicing and maintenance as often as may be necessary to ensure proper operation. You must have all in-ternal repairs or internal adjustments to your CB transmitter made in ac-cordance with the Technical Regula-tions (see subpart E). The internal re-pairs or internal adjustments should be performed by or under the immediate
551 Federal Communications Commission § 95.601 supervision and responsibility of a per-son certified as technically qualified to perform transmitter maintenance and repair duties in the private land mobile services and fixed services by an orga-nization or committee representative of users in those services. (c) Except as provided in paragraph (d) of this section, each internal repair and each internal adjustment of a CB transmitter in which signals are trans-mitted must be made using a nonradi-ating (‘‘dummy’’) antenna. (d) Brief test signals (signals not longer than one minute during any five minute period) using a radiating an-tenna may be transmitted in order to: (1) Adjust an antenna to a trans-mitter; (2) Detect or measure radiation of en-ergy other than the intended signal; or (3) Tune a receiver to your CB trans-mitter. (Secs. 4(i) and 303(r), Communications Act of 1934, as amended, 47 U.S.C. 154(i) and 303(r), and sec. 553 of the Administrative Proce-dures Act, 5 U.S.C. 553) [48 FR 24894, June 3, 1983, as amended at 49 FR 20673, May 16, 1984]
