§  90.405   Permissible communications.

   (a) Stations licensed under this part may transmit only the following
   types of communication:

   (1) Any communication related directly to the imminent safety-of-life
   or property;

   (2) Communications directly related and necessary to those activities
   which make the licensee eligible for the station license held under
   this part. In addition, when communication service is provided under
   the cooperative sharing provisions of § 90.179, the licensee providing
   such service may transmit communications related to the activities for
   which the parties receiving the service would be eligible to be
   licensed.

   (3) Communications for testing purposes required for proper station and
   system maintenance. However, each licensee shall keep such tests to a
   minimum and shall employ every measure to avoid harmful interference.

   (b) The provisions contained in paragraph (a) of this section do not
   apply where a single base station licensee has been authorized to use a
   channel above 470 MHz on an exclusive basis, or to stations licensed
   under this part that are classified as CMRS providers under part 20 of
   this chapter.
