   (6) For secondary operations only fixed stations are permitted. At the
   locations specified in (b)(4) of this section, secondary operations are
   performed in the 1429-1431.5 MHz band. For all other locations,
   secondary operations are performed in the 1427-1429.5 MHz band. The
   maximum power is 1 watt EIRP.

   (7) For primary operations base, mobile, operational fixed and
   temporary fixed operations are permitted.

   (i) At the locations specified in paragraph (b)(4) of this section,
   primary operations are performed in the 1427-1429 MHz and 1431.5-1432
   MHz bands. The maximum ERP limitations are as follows:

   (10) Licensees, however, may combine contiguous channels up to 50 kHz,
   and more than 50 kHz only upon a showing of adequate justification.

   (11) For any operation in the 1427-1432 MHz band, the predicted or
   measured field strength--in the WMTS primary band--at the location of

   the locations specified in (b)(4) of this section, WMTS is primary in
   the 1429-1431.5 MHz band. For all other locations, WMTS is primary in

   (c) Authorized uses. (1) Use of these bands is limited to telemetering
   purposes.

   (2) Base stations authorized in these bands shall be used to perform
   telecommand functions with associated mobile telemetering stations.
   Base stations may also command actions by the vehicle itself, but will
