Sec. 90.655  Special licensing requirements for Specialized Mobile Radio 
          systems.

    End users of conventional or trunked Specialized Mobile Radio 
systems that have control stations that require FAA clearance, as 
specified in subpart B of part 17 of Title 47 of the Code of Federal 
Regulations, 47 CFR 17.7-17.17, or that may have a significant 
environmental effect, as defined by Sec. 1.1307, or that are located in 
a ``quiet zone'', as defined by 47 CFR 90.177 must be individually 
licensed for such control stations prior to construction or operation. 
All other end users' operations will be within the scope of the base 
station licensee. All end users, however, continue to be responsible to 
comply with 47 CFR part 90 and other federal laws.
