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).
