Sec. 22.161  Application requirements for ASSB.



    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.
