Sec.  23.38   Experimental points of communication, limitations.

   Experimental (Research) or Experimental (Developmental) stations licensed to
   operate as point-to-point telegraph or telephone stations in the fixed
   public service may communicate only with other experimental stations located
   within  the  continental  limits of the United States (except Alaska):
   Provided, however, That upon application the Commission may authorize such a
   station to communicate with one or more specific points in Alaska, Hawaii,
   possessions of the United States, or with a specific foreign point. In each
   such case, the Commission will determine the nature of the experimental
   transmissions which may be made to such point of communication.
