Notes:
^1A1A, F1B, J2A and J2B are permitted provided they do not cause harmful
interference to H2B, J3E, J7B and J9W.
^2For use with an authorized bandwidth of 8.0 kilohertz at radiobeacon
stations. A3E will not be authorized:
(i) At existing radiobeacon stations that are not authorized to use A3 and
at new radiobeacon stations unless specifically recommended by the FAA for
safety purposes.
(ii) At existing radiobeacon stations currently authorized to use A3,
subsequent to January 1, 1990, unless specifically recommended by the FAA
for safety purposes.
^3In the band 117.975-136 MHz, the authorized bandwidth is 25 kHz for
transmitters approved after January 1, 1974.
^4Applicable only to Survival Craft Stations and to the emergency locator
transmitters and emergency locator transmitter test stations employing
modulation in accordance with that specified in § 87.141 of the Rules. The
specified bandwidth and modulation requirements shall apply to emergency
locator transmitters for which approval is granted after October 21, 1973.
^5This emission may be authorized for audio frequency shift keying and phase
shift keying for digital data links on any frequency listed in
§ 87.263(a)(1), § 87.263(a)(3) or § 87.263(a)(5). 13K0A2D emission may be
authorized on frequencies not used for voice communications. If the channel
is used for voice communications, 13K0A9W emission may be authorized,
provided the data is multiplexed on the voice carrier without derogating
voice communications.
^6Applicable to operational fixed stations in the bands 72.0-73.0 MHz and
75.4-76.0 MHz and to CAP stations using F3 on 143.900 MHz and 148.150 MHz.
^7Applicable to operational fixed stations presently authorized in the band
73.0-74.6 MHz.
^8 The authorized bandwidth is equal to the necessary bandwidth for
frequency or digitally modulated transmitters used in aeronautical
telemetering and associated aeronautical telemetry or telecommand stations
that operate in the 1435-1525 MHz, 2345-2395 MHz, or 5091-5150 MHz band. The
necessary bandwidth must be computed in accordance with part 2 of this
chapter.
^9To be specified on license.
^10H2B must be used by stations employing digital selective calling.
^11For A1A, F1B and single sideband emissions, except H2B, the assigned
frequency must be 1400 Hz above the carrier frequency.
^12R3E, H3E, and J3E will be authorized only below 25000 kHz. Only H2B, J3E,
J7B, and J9W are authorized, except that A3E and H3E may be used only on
3023 kHz and 5680 kHz for search and rescue operations.
^13The letters āK, L, M, Q, V, W, and Xā may also be used in place of the
letter āPā for pulsed radars.
^14Authorized for use at radiobeacon stations.
^15Applicable only to transmitters of survival craft stations, emergency
locator transmitter stations and emergency locator transmitter test stations
approved after October 21, 1973.
^16Authorized for use by aircraft earth stations. Lower values of necessary
and authorized bandwidth are permitted.
^17In the band 117.975-137 MHz, the Commission will not authorize any 8.33
kHz channel spaced transmissions or the use of their associated emission
designator within the U.S. National Airspace System, except, on an optional
basis, by Aeronautical Enroute Stations and Flight Test Stations, or by
avionics equipment manufacturers which are required to perform installation
and checkout of such radio systems prior to delivery to their customers. For
transmitters certificated to tune to 8.33 kHz channel spacing as well as 25
kHz channel spacing, the authorized bandwidth is 8.33 kHz when tuned to an
8.33 kHz channel.
^18Authorized only for Universal Access Transceiver use at 978 MHz.
(b) For other emissions, an applicant must determine the emission designator
by using part 2 of this chapter.
(c) A license to use radiotelephony includes the use of tone signals or
signaling devices whose sole function is to establish or maintain voice
communications.
