(b) Experimentations under contractual agreement with the United States Government, or for export purposes. (c) Communications essential to a research project. (d) Technical demonstrations of equipment or techniques. (e) Field strength surveys by persons not eligible for authorization in any other service. (f) Demonstration of equipment to prospective purchasers by persons engaged in the business of selling radio equipment. (g) Testing of equipment in connection with production or regulatory approval of such equipment. (h) Development of radio technique, equipment or engineering data not related to an existing or proposed service, including field or factory testing or calibration of equipment. (i) Development of radio technique, equipment, operational data or engineering data related to an existing or proposed radio service. (j) Limited market studies. (k) Types of experiments that are not specifically covered under paragraphs (a) through (j) of this section will be considered upon demonstration of need for such additional types of experiments. [63 FR 64202, Nov. 19, 1998; 64 FR 43094, Aug. 9, 1999] For the purpose of this part, the following definitions shall be applicable.

The power assigned to a radio station by the Commission and specified in the instrument of authorization. Experimental radio service. 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 that could not be conducted without the benefit of such communications. Experimental station. A station utilizing radio waves in experiments with a view to the development of science or technique. Fixed service. A radiocommunication service between specified fixed points. Fixed station. A station in the fixed service. Harmful interference. Any radiation or induction that endangers the functioning of a radionavigation or safety service, or obstructs or repeatedly interrupts a radio service operating in accordance with the Table of Frequency Allocations and other provisions of part 2 of this chapter. Landing area.

Land station. A station in the mobile service not intended for operation while in motion. Mobile service. A radiocommunication service between mobile and land stations, or between mobile stations. Mobile station. A station in a mobile service intended to be used while in motion or during halts at unspecified points. Person. An individual, partnership, association, joint stock company, trust, or corporation. Public correspondence. Any telecommunication that offices and stations, by reason of their being at the disposal of the public, must accept for transmission. Radio service.
