                         COMMISSION (CONTINUED)
 
PART 23--INTERNATIONAL FIXED PUBLIC RADIOCOMMUNICATION SERVICES--Table of Contents
 
Sec. 23.13  Types of emission.

    Stations in the international fixed public radiocommunication 
services may be authorized to use any of the types of emission or 
combinations thereof, described in part 2 of this chapter, as well as 
new types which may be developed: Provided, That harmful interference to 
adjacent operations is not caused thereby, And provided further, That 
the intelligence to be transmitted will use the bandwidth

requested to a degree of efficiency compatible with the current state of 
the art. A determination of the possibilities of interference will be 
made as outlined in Sec. 23.20. In certain cases frequencies or 
emissions may be authorized on a temporary basis to determine if 
interference will occur. During normal operations, emissions shall be 
centered about an assigned frequency. Non-centered emissions may be 
employed for short periods of time as needed to avoid interfering 
signals or meet fluctuating traffic loading: Provided, That the occupied 
bandwidth of these emissions be contained within the authorized 
bandwidth, And provided further, That prior to any such use, the 
Commission be notified of the reference frequency or frequencies 
proposed to be used in lieu of the assigned frequency.
