§ 97.313   Transmitter power standards.

   (a) An amateur station must use the minimum transmitter power necessary to
   carry out the desired communications.

   (b) No station may transmit with a transmitter power exceeding 1.5 kW PEP.

   (c) No station may transmit with a transmitter power output exceeding 200 W
   PEP:

   (1) On the 10.10-10.15 MHz segment;

   (2) On the 3.525-3.60 MHz, 7.025-7.125 MHz, 21.025-21.20 MHz, and 28.0-28.5
   MHz  segment when the control operator is a Novice Class operator or a
   Technician Class operator; or

   (3) The 7.050-7.075 MHz segment when the station is within ITU Regions 1 or
   3.

   (d) No station may transmit with a transmitter power exceeding 25 W PEP on
   the VHF 1.25 m band when the control operator is a Novice operator.

   (e) No station may transmit with a transmitter power exceeding 5 W PEP on
   the UHF 23 cm band when the control operator is a Novice operator.

   (f) No station may transmit with a transmitter power exceeding 50 W PEP on
   the UHF 70 cm band from an area specified in paragraph (a) of footnote US270
   in § 2.106, unless expressly authorized by the FCC after mutual agreement, on
   a case-by-case basis, between the Regional 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°.

   (g) No station may transmit with a transmitter power exceeding 50 W PEP on
   the 33 cm band from within 241 km of the boundaries of the White Sands
   Missile Range. Its boundaries are those portions of Texas and New Mexico
   bounded on the south by latitude 31°41′ North, on the east by longitude
   104°11′ West, on the north by latitude 34°30′ North, and on the west by
   longitude 107°30′ West.

   (h) No station may transmit with a transmitter power exceeding 50 W PEP on
   the 219-220 MHz segment of the 1.25 m band.

   (i) No station may transmit with an effective radiated power (ERP) exceeding
   100  W  PEP  on  the  60 m band. For the purpose of computing ERP, the
   transmitter  PEP  will be multiplied by the antenna gain relative to a
   half-wave dipole antenna. A half-wave dipole antenna will be presumed to
   have a gain of 1 (0 dBd). Licensees using other antennas must maintain in
   their station records either the antenna manufacturer's data on the antenna
   gain or calculations of the antenna gain.

   (j) No station may transmit with a transmitter output exceeding 10 W PEP
   when the station is transmitting a SS emission type.
