A service in which Radio waves are employed for purposes of experimentation in the radio art or for purposes of providing essential communications for research projects which could not be conducted without the benefit of such communications. " The research projects referred to were originally intended to be research into the propagation of radio waves or the effects of such on physical or chemical processes, etc. It was NOT intended to mean provision of communications for someone doing some other kind of research not involving the nature of radio waves. In other words, the radio waves were the object of the research, not a tool or means of instrumentation. Otherwise it could be construed to mean, for instance, provision of two-way communications for someone doing research into the most efficient method of dispatching pizza delivery vans, or garbage trucks, or both in the same vehicle. " In real life, new and novel ways to use radio communications properly fall under a *Developmental* authorization in an existing radio service rather than an authorization in the Experimental Radio Service. Specific examples from the recent past were the provision of vehicle location systems and mobile digital data, developmental authorizations in the various land mobile radio services in years gone by. Ditto for cellular radiotelephones in the Common Carrier Radio Service. But, alas, there arose a new breed in Washington who knew not what good regulatory practice was, would not listen to their elders and betters, and therefore would release Experimental Radio authorizations for any and all purposes, even when they shouldn't. And it makes it much harder for the working radio inspector, who is the front-line interface between the radio user and pure chaos, because the folks involved were prone to grant anything to anyone without adequate reason, leading to huge screwups in real life. "And as for remote TV and data transfer for robotics, the Business Radio Service has plenty of capability in the microwave regions. Educational institutions are eligible in that service. One should tailor one's project to live within them or do without. "Just like driving a car on the highway - how would YOU feel if soemone somehow got the OK to speed, make unsafe lane changes, etc. and you had to obey all the regular laws." Cousin Charlie should know - he's been out there a LONG time! -=Ploni=- -- Via apple!mailcom, Fido 1:204/444
