   safety as required by  Sec. 17.4 of the Commission's Rules; or the proposed
   antenna or tower structure does not exceed 6.1 meters (20 feet) above ground
   level or above an existing man-made structure (other than an antenna

   operate the proposed station during the pendency of the application for a
   period not to exceed one hundred eighty (180) days upon the filing of a
   properly completed formal Form 601 application that complies with  Sec. 90.127 of
   this part. Conditional authority ceases immediately if the application is
   dismissed by the Commission. All other categories of applications listed in
    Sec. 90.175(i) of this part that do not require evidence of frequency
   coordination are excluded from the provisions of this section.

   (d) Conditional authorization does not prejudice any action the Commission
   may take on the subject application. Conditional authority is accepted with
   the express understanding that such authority may be modified or canceled by
   the Commission at any time without hearing if, in the Commission's
   discretion, the need for such action arises. Consistent with  Sec. 90.175(g) of
   this part, the applicant assumes all risks associated with operation under
   conditional authority, the termination or modification of conditional
   authority, or the subsequent dismissal or denial of its application.
   Authority reverts back to the original licensee if an assignee or
   transferee's conditional authority is canceled.

   authority shall be identified by a temporary call sign consisting of the
   prefix “WT” followed by the applicant's local seven digit business telephone
