Sec.  25.211   Video transmissions in the Fixed-Satellite Service.

   

   (a) Downlink analog video transmissions in the band 3700-4200 MHz
   shall be transmitted only on a center frequency of 3700+20N MHz, where
   N=1 to 24. The corresponding uplink frequency shall be 2225 MHz
   higher.

   (b) All 4/6 GHz analog video transmissions shall contain an energy
   dispersal signal at all times with a minimum peak-to-peak bandwidth
   set at whatever value is necessary to meet the power flux density
   limits specified in Sec. 25.208(a) and successfully coordinated
   internationally and accepted by adjacent U.S. satellite operators
   based on the use of state of the art space and earth station
   facilities. Further, all transmissions operating in frequency bands
   described in Sec. 25.208 (b) and (c) shall also contain an energy
   dispersal signal at all times with a minimum peak-to-peak bandwidth
   set at whatever value is necessary to meet the power flux density
   limits specified in Sec. 25.208(b) and (c) and successfully coordinated
   internationally and accepted by adjacent U.S. satellite operators
   based on the use of state of the art space and earth station
   facilities. The transmission of an unmodulated carrier at a power
   level sufficient to saturate a transponder is prohibited, except by
   the space station licensee to determine transponder performance
   characteristics. All 12/14 GHz video transmissions for TV/FM shall
   identify the particular carrier frequencies for necessary coordination
   with adjacent U.S. satellite systems and affected satellite systems of
   other administrations.

   (c) All initial analog video transmissions shall be preceded by a
   video test transmission at an uplink e.i.r.p. at least 10 dB below the
   normal operating level. The earth station operator shall not increase
   power until receiving notification from the satellite network control
   center that the frequency and polarization alignment are satisfactory
   pursuant to the procedures specified in Sec. 25.272. The stationary earth
   station operator that has successfully transmitted an initial video
   test signal to a satellite pursuant to this paragraph is not required
   to make subsequent video test transmissions if subsequent
   transmissions are conducted using exactly the same parameters as the
   initial transmission.

   (d) In the 6 GHz band, an earth station with an equivalent diameter of
   9 meters or smaller may be routinely licensed for transmission to full
   transponder services if the maximum power into the antenna does not
   exceed 450 watts (26.5 dBW). In the 14 GHz band, an earth station with
   an equivalent diameter of 5 meters or smaller may be routinely
   licensed for transmission of full transponder services if the maximum
   power into the antenna does not exceed 500 watts (27 dBW).
