(f) No station may transmit with a transmitter power exceeding 50 W
PEP on the UHF 70 cm band from an area specified in footnote US7 to
Sec. 2.106 of part 2, unless expressly authorized by the FCC after
mutual agreement, on a case-by-case basis, between the District Director
of the applicable field facility and the military area frequency
coordinator at the applicable military base. An Earth station or
telecommand station, however, may transmit on the 435-438 MHz segment
with a maximum of 611 W effective radiated power (1 kW equivalent
isotropically radiated power) without the authorization otherwise
required. The transmitting antenna elevation angle between the lower
half-power (-3 dB relative to the peak or antenna bore sight) point and
the horizon must always be greater than 10 degrees.
2.106 Footnote US7
(a) Those portions of Texas and New Mexico bounded on the south by latitude
31°45' North, on the east by 104°00' West, on the north by latitude 34°30'
North, and on the west by longitude 107°30' West;
The FCC has a nice map of the areas affected by the 50w limit at
