So I found these rules:
(2) No amateur station shall transmit from those portions of Texas and New Mexico that are bounded by latitudes 31°41 ′ and 34°30 ′ North and longitudes 104°11 ′ and 107°30 ′ West; or from outside of the United States and its Region 2 insular areas.
(3) No amateur station shall transmit from those portions of Colorado and Wyoming that are bounded by latitudes 39° and 42° North and longitudes 103° and 108° West in the following segments: 902.4–902.6 MHz, 904.3–904.7 MHz, 925.3–925.7 MHz, and 927.3–927.7 MHz.
But I can't find exactly what the government needs 30MHz of bandwidth for, especially in the middle of New Mexico.
What is the reason for this restriction?
