Sec.  5.83   Cancellation provisions.

   The applicant for a station in the Experimental Radio Services accepts the
   license with the express understanding: (a) that the authority to use the
   frequency or frequencies assigned is granted upon an experimental basis only
   and does not confer any right to conduct an activity of a continuing nature;
   and

   (b) that said grant is subject to change or cancellation by the Commission
   at any time without hearing if in its discretion the need for such action
   arises. However, a petition for reconsideration or application for review
   may be filed to such Commission action.
