   of issue when the operator is awaiting FCC action on an application.

   (c) When the operator is on duty and in charge of transmitting systems, or
   performing service, maintenance or inspection functions, the license or
   permit document, or a photocopy thereof, or a copy of the application and
   PPC(s) received by the FCC, must be posted or in the operator's personal
   possession,  and  available  for  inspection  upon  request  by  a FCC
   representative.

   (d)  The  operator  on  duty and in charge of transmitting systems, or
   performing  service, maintenance or inspection functions, shall not be
