§  74.503   Frequency selection.

   (a) Each application for a new station or change in an existing station
   shall be specific with regard to frequency. In general, the lowest
   suitable frequency will be assigned which, on an engineering basis,
   will not cause harmful interference to other stations operating in
   accordance with existing frequency allocations.

   (b) Where it appears that interference may result from the operation of
   a new station or a change in the facilities of an existing station, the
   Commission may require a showing that harmful interference will not be
   caused to existing stations or that if interference will be caused the
   need for the proposed service outweighs the loss of service due to the
   interference.
