Spread spectrum (SS) uses a wide bandwidth which would cause too much crowding on the relatively narrow bands below UHF.

See FCC rules: §97.305 Authorized emission types.

Tips:

SS222

The 2s are spread into 222

CEPT - European Conference of Postal and Telecommunications Administrations. C "European" PT

Hint: Usually not allowed, but they make exCEPTions.

Fun Fact, from Wikipedia:

The acronym comes from the French version of its name:

Conférence Européenne des administrations des Postes et des Télécommunications.

Rules in Sections 97.315 & 97.317 apply to manufacturers of amplifiers or kits. An individual Amateur may build one for personal use. An unlicensed individual may not build or modify an amplifier capable of operating below 144 MHZ without an FCC grant of certification. The certification grant includes spurious emission standards and may not be used for Citizen's Band frequencies (26 - 28 MHz).

Silly memory trick: Canadians are known for saying, “Eh?” So think of the question as, “Line, eh?” 🙂

Real explanation:

Private land mobile radio services, 47 C.F.R. § 90.7 (2010):

Line A. An imaginary line within the U.S., approximately paralleling the U.S.-Canadian border, north of which Commission coordination with the Canadian authorities in the assignment of frequencies is generally required. It begins at Aberdeen, Washington, running by great circle arc to the intersection of 48° N., 120° W., then along parallel 48° N., to the intersection of 95° W., thence by great circle arc through the southernmost point of Duluth, Minnesota, thence by great circle arc to 45° N., 85° W., thence southward along meridian 85° W. to its intersection with parallel 41° N., to its intersection with meridian 82° W., thence by great circle arc through the southernmost point of Bangor, Maine, thence by great circle arc through the southernmost of Searsport, Maine, at which point it terminates.

Private land mobile radio services, 47 C.F.R. § 97.3 (2010):

29. Line A. Begins at Aberdeen, WA, running by great circle arc to the intersection of 48° N, 120° W, thence along parallel 48° N, to the intersection of 95° W, thence by great circle arc through the southernmost point of Duluth, MN, thence by great circle arc to 45° N, 85° W, thence southward along meridian 85° W, to its intersection with parallel 41° N, thence along parallel 41° N, to its intersection with meridian 82° W, thence by great circle arc through the southernmost point of Bangor, ME, thence by great circle arc through the southernmost point of Searsport, ME, at which point it terminates.

Line A roughly parallels the border between the Lower 48 States and Canada, about one degree south of the border. Line B is the Canadian counterpart, running about one degree north of the border.

Check out the following for more information: Private land mobile radio services, 47 C.F.R. § 97.303 (2010):

(m) In the 70 cm band:

(1) No amateur station shall transmit from north of Line A in the 420-430 MHz segment. See §97.3(a) for the definition of Line A.

reference:

http://www.gpo.gov/fdsys/pkg/CFR-2010-title47-vol5/pdf/CFR-2010-title47-vol5.pdf

pages 244 and 609

Memory aid: "Stay away from 420 when you're up high." (I know, groan, but you don't forget it.)

Another memory aid: Only those below the line can use the lower end of the 70cm band

TEST TIP: "The southern (low) edge of 70cm is not for those up north."

Title 47 CFR Part 97 § 97.3(a)(33)

(33) National Radio Quiet Zone. The area in Maryland, Virginia and West Virginia Bounded by 39°15′ N on the north, 78°30′ W on the east, 37°30′ N on the south and 80°30′ W on the west.

Reference:

https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-97#p-97.3(a)(33)

From Wikipedia:

The National Radio Quiet Zone (NRQZ) is a large area of land in the United States designated as a radio quiet zone, in which radio transmissions are restricted by law to facilitate scientific research and the gathering of military intelligence. About half of the zone is located in the Blue Ridge Mountains of west-central Virginia while the other half is in the Allegheny Mountains of east-central West Virginia; a small part of the zone is in the southernmost tip of the Maryland panhandle.

TEST TIP: "OBSERVE the Quiet Zone at all hours."

When neither the amateur nor his or her employer has a pecuniary interest in the communications

Last edited by jasonsanroma. Register to edit

The answer is:

Communications transmitted for hire or material compensation, except as otherwise provided in the rules

All the other listed types of communications are permitted.

03/04/2011 -- In a Report and Order adopted February 22 and released March 4, 2011, the Federal Communications Commission has eliminated the requirement that amateur stations transmitting Spread Spectrum use Automatic Power Control (APC) to reduce transmitter power. At the same time, the Commission has reduced the maximum power of a Spread Spectrum emission from 100 to 10 W PEP.

The R&O explains the Commission’s actions this way: “We believe that these rules changes will (1) encourage individuals who can contribute to the advancement of the radio art to more fully utilize SS technologies in experimentation, and (2) balance the interests of all users in mixed-mode and mixed-service frequency bands until sharing protocols are sufficiently developed to avoid interference.”

All amateurs, except Novices, may put auxiliary stations on the air [97.201(a)].

Note: Since the FCC no longer issues licenses for Novice and Advanced, you might be tempted to select "Any licensed amateur operator" However, there are still individuals who hold Novice and Advanced licenses (the FCC has not forced them to upgrade.), And those who have Novice licenses are not allowed to handle auxiliary stations.

Business-related messages are never allowed to be sent over amateur radio, even if it's for a non-profit organization.

A maritime satellite service would most likely be a service for connecting to seafaring vessels -- a web search turned up nothing useful -- which would not be part of the amateur service.

Communications incidental to the purpose of the amateur service and remarks of a personal nature are always welcome on amateur radio, so this should generally be the most obvious choice -- good thing it's the correct one.

The FCC regulation on Special Temporary Authority (47 C.F.R. 1.931) does not specifically address amateur radio, but in analogous situations FCC authority is recognized to grant an STA to "conduct tests to determine necessary data for the preparation of an application for regular authorization". (§1.931(b)(2)(iii)), i.e., for experimentation. The best answer is therefore "to provide for experimental communications."
