>For services that are aimed at people who just want to communicate, getting a license won't involve anything like schematic diagrams--if a license is even required. For people who might be interested in what those 'unlicensed' services are, they include: - FRS (the Family Radio Service[0]), which is typified by the sort of $20 bubble pack radios you can buy at a sporting goods store; - MURS (the Multi-Use Radio Service[1]), which is common in commercial radios used by e.g. staff at big box stores; - CBRS (the Citizens Band Radio Service[2]), which is probably familiar to most from "any movie involving truck drivers". These services may have licensing/approval rules for equipment, but not for individuals using them.
