  §  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.

   (k) No station may transmit in the 135.7-137.8 kHz (2200 m) band with a
   transmitter power exceeding 1.5 kW PEP or a radiated power exceeding 1
   W EIRP.

   (l) No station may transmit in the 472-479 kHz (630 m) band with a
   transmitter power exceeding 500 W PEP or a radiated power exceeding 5 W
   EIRP, except that in Alaska, stations located within 800 kilometers of
   the Russian Federation may not transmit with a radiated power exceeding
   1 W EIRP.

   (m) No station may transmit with a peak equivalent isotropically
   radiated power (EIRP) exceeding 316 W in the 76-81 GHz (4 mm) band.
