The same law also adds new restrictions on the recreational use of drones, which the ARRL says would include most uses by hams. Requirements include registering as a "modeler" and labeling your drone with your FAA registration number; passing an aeronautical knowledge and safety test; keeping the drone within sight of the operator or of another person in direct communication with the operator, and never flying over groups of people or near emergency or disaster recovery sites. (The advisory circular with details on the requirements - <https://tinyurl.com/y4h2z88x> - does not address the use of "recreational" drones in association with amateur radio emergency or public service activities. If your group uses drones for these purposes, we suggest talking with your local director of emergency management about how and whether they may be used.)
