Sec.  22.161   Application requirements for ASSB.

   

   Link to an amendment published at  70 FR 19308 , Apr. 13, 2005.

   Applications  for base stations employing amplitude compandored single
   sideband modulation (ASSB) must contain the following information:

   (a)    The    application   must   describe   fully   the   modulation
   characteristics,  emission  and  occupied  bandwidth,  and specify the
   center  frequency of the emission for each channel, carrier frequency,
   and pilot channels, if any. The emission must fall completely within a
   channel   assignable   for   two-way   operation  in  the  Paging  and
   Radiotelephone  Service,  Rural  Radiotelephone  Service  or  Offshore
   Radiotelephone Service.

   (b) The application must contain interference studies between stations
   within  an  authorized  bandwidth,  whether FM-to-ASSB, ASSB-to-FM, or
   ASSB-to-ASSB  in accordance with the following: For ASSB stations, the
   transmitter  nearest  to  the  protected  station  must  be  used. The
   effective  radiated  power  in  the direction of the protected station
   must  be  the  sum  of  the  peak  effective  radiated  power  of  all
   transmitters  in the group, in the direction of the protected station.
   The  antenna  center of radiation height above average terrain must be
   the  highest  antenna center of radiation height of any transmitter in
   the  group  in  the direction of the protected station. The channel of
   the  group  is assumed to be the same as that of the protected station
   (co-channel), and studies must be made in accordance with Sec. 22.567.
