Sec. 90.658  Loading data required for base station licensees of trunked 
          Specialized Mobile Radio systems to acquire additional 
          channels or to renew trunked systems licensed before June 1, 
          1993.

    (a) A base station licensee of a trunked Specialized Mobile Radio 
system that applies for additional channels to expand an existing system 
or to construct a new system within 40 miles of its existing system, or 
a base station licensee of a trunked system applying for its first 
renewal in a waiting list area for a system licensed before June 1, 1993 
must identify on the appropriate application form the number of mobiles 
and control stations loaded on its system as calculated in paragraph (b) 
of this section.
    (b) The number described in paragraph (a) of this section must be 
calculated by averaging the number of mobiles and control stations 
operating on a licensee's system on the first business day of each of 
the six months immediately preceding the filing of an application and 
must be based on the licensee's business records for that period. 
Alternative calculations will be permitted upon good cause showings of 
special circumstances.
    (c) Business records may constitute invoices, customer service 
agreements, customer lists or any other type of record kept in the 
ordinary course of business.
    (d) The FCC will use the loading data required by this section to 
determine whether the licensee's existing system has a sufficient number 
of mobiles as required by 47 CFR chapter I to qualify for additional 
channels or for the first renewal of trunked systems licensed before 
June 1, .
