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 system applying for its first
   renewal in a waiting list area for a system licensed before June 1, 1993
   must identify, using FCC Form 601, 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, 1993.
