GMRS transmitters, for example, are supposed to be accompanied by a copy of the applicable rules and an application for a license. I believe VHF marine rigs are also supposed to have an application in them (and since there's provision for temporary operation until the real license comes, it's hard to see how this is much of a deterrent.) CBs don't need licenses, of course, but inclusion of a copy of the rules is mandatory. Some amateur manuals carry a warning about this, and some don't. Like the manual for my Kenwood HT, which warn against illegal operation resulting from mods, but not from bootlegging. Commercial radios are odd: there is a one-paragraph provision of Part 90 making it illegal for anyone to program a frequency into a radio unless the user is licensed for that frequency, but I have no idea if over-the-counter HTs with crystals included have any warning in their manuals or papers. Licensing is the sort of thing businesses often pay their dealers to take care of, and those professional dealers would seem to have some responsibility to their customers. I've heard talk that the FCC might once again require a commercial licence for servicing these radios. In short, there seems plenty of precedent for requiring notice of possible licensing requirements in the documentation. Oh, and a short editorial note. Throwing the book at people *because* they have a license and should have known better, but not at ordinary blokes, strikes me as excusing ignorance of the law, which is not ordinarily done. A note in a manual and an included application don't seem like onerous requirements after the trouble and expense of type-acceptance, and might do even more to insure compliance with the law. -drt ------------------------------------------------------------------------ |David R.
