§ 95.639 Maximum transmitter power.
(a) No GMRS transmitter, under any condition of modulation, shall exceed:
(1) 50 W Carrier power (average TP during one unmodulated RF cycle) when
transmitting emission type A1D, F1D, G1D, A3E, F3E or G3E.
(2) 50 W peak envelope TP when transmitting emission type H1D, J1D, R1D,
H3E, J3E or R3E.
(b) No R/C transmitter, under any condition of modulation, shall exceed a
carrier power or peak envelope TP (single-sideband only) of:
(1) 4 W in the 26-27 MHz frequency band, except on channel frequency 27.255
MHz;
(2) 25 W on channel frequency 27.255 MHz;
(3) 0.75 W in the 72-76 MHz frequency band.
(c) No CB transmitter, under any condition of modulation, shall exceed:
(1) 4 W Carrier power when transmitting emission type A1D or A3E;
(2) 12 W peak envelope TP when transmitting emission type H1D, J1D, R1D,
H3E, J3E or R3E. Each CB transmitter which transmits emission type H3E, J3E
or R3E must automatically prevent the TP from exceeding 12 W peak envelope
TP or the manufacturer's rated peak envelope TP, whichever is less.
(d) No FRS unit, under any condition of modulation, shall exceed 0.500 W
effective radiated power (ERP).
(e) The maximum transmitter output power authorized for LPRS stations is 100
mW.
(f) In the MedRadio Service:
(1) For transmitters operating in the 401-406 MHz band that are not excepted
under § 95.627(b) from the frequency monitoring requirements of § 95.627(a),
the maximum radiated power in any 300 kHz bandwidth by MedRadio transmitters
operating at 402-405 MHz, or in any 100 kHz bandwidth by MedRadio
transmitters operating at 401-402 MHz or 405-406 MHz shall not exceed 25
microwatts EIRP. For transmitters that are excepted under § 95.627(b) from
the frequency monitoring requirements of § 95.627(a), the power radiated by
any station operating in 402-405 MHz shall not exceed 100 nanowatts EIRP
confined to a maximum total emission bandwidth of 300 kHz centered at 403.65
MHz, the power radiated by any station operating in 401-401.85 MHz or
405-406 MHz shall not exceed 250 nanowatts EIRP in any 100 kHz bandwidth and
the power radiated by any station operating in 401.85-402 MHz shall not
exceed 25 microwatts in the 150 kHz bandwidth. See § § 95.633(e).
(2) For transmitters operating in 413-419 MHz, 426-432 MHz, 438-444 MHz, or
451-457 MHz bands, the peak EIRP over the frequency bands of operation shall
not exceed the lesser of 1 mW or 10 log B—7.782 dBm, where B is the 20 dB
emission bandwidth in MHz; and the peak power spectral density shall not
exceed 800 microwatts per megahertz in any 1 megahertz band.
(3) For transmitters operating in the 2360-2390 MHz band, the maximum EIRP
over the frequency bands of operation shall not exceed the lesser of 1 mW or
10*log (B) dBm, where B is the 20 dB emission bandwidth in MHz.
(4) For transmitters operating in the 2390-2400 MHz band, the maximum EIRP
over the frequency bands of operation shall not exceed the lesser of 20 mW
or 16 + 10*log (B) dBm, where B is the 20 dB emission bandwidth in MHz.
(5) The antenna associated with any MedRadio transmitter must be supplied
with the transmitter and shall be considered part of the transmitter subject
to equipment authorization. Compliance with these EIRP limits may be
determined as set forth in § 95.627(g) or § 95.628(h), as applicable.
(g) The maximum field strength authorized for WMTS stations in the 608-614
MHz band is 200 mV/m, measured at 3 meters. For stations in the 1395-1400
MHz and 1427-1429.5 MHz bands, the maximum field strength is 740 mV/m,
measured at 3 meters.
(h) No MURS unit, under any condition of modulation, shall exceed 2 Watts
transmitter power output.
(i) DSRCS-OBUs are governed under subpart L of this part, except the maximum
output power for portable DSRCS-OBUs is 1.0 mW. For purposes of this
paragraph, a portable is a transmitting device designed to be used so that
the radiating structure(s) of the device is/are within 20 centimeters of the
body of the user.
