Spurious is defined as "Not being what it purports to be; false or fake."

Spurious emissions are "false" emissions that accompany legitimate emissions. Usually they are caused by a poorly calibrated or faulty transmitter. On a spectrum analyzer they would show up as being spikes of RF energy sometimes adjacent to the real signal and sometimes at random intervals usually close by.

These emissions are "spurious" or "false" because they are not necessary to receive the information and they are outside the normal bandwidth needed for the signal.

Tip: The correct answer is the only one that contains the word "emission" from the question.

Remember that SSTV (Slow Scan TV) transmissions have to fit into the same bandwidth as common SSB voice transmission.

Just like any SSTV transmission, 3 KHz is an acceptable bandwidth.

Answer: 3KHz

§ 97.13 Restrictions on station location.

(b) A station within 1600 m (1 mile) of an FCC monitoring facility must protect that facility from harmful interference. Failure to do so could result in imposition of operating restrictions upon the amateur station by a District Director pursuant to § 97.121 of this part. Geographical coordinates of the facilities that require protection are listed in § 0.121(c) of this chapter.

TEST TIP: These monitoring stations tend to be little shacks with antenna arrays out in an empty field set away from likely sources of interference (see https://goo.gl/maps/msXm2pqVgJSAPeCj6).

With that visual in mind, you can think to yourself "there should be no interference within a COUNTRY MILE (1 mile) of the FCC shack."

The amateur radio service is secondary in this band. This means that amateur stations operating in this band (including repeaters) must eliminate any interference to primary users.

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:

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."

Memory trick: both the question and answer contain National Radio

This is an overlapping jurisdiction question. The FAA regulates Airspace that might endanger aircraft so their regulations need to be consulted and it will then need to registered with the FCC as required by part 17.

Hint: The question deals with Aviation and Amateur Radio. The correct answer references both the FAA and FCC.

State and local zoning. While there have been attempts to apply it to HOA and other situations (CC&R's), these attempts have not yet succeeded.

From http://www.arrl.org/prb-1

The 11 page document has been codified at Section 97.15(b). This is a short summary of the 11 page PRB-1. PRB-1 states that local governments must reasonably accommodate amateur operations, but they may still zone for height, safety and aesthetics concerns.

As stated earlier, it is important to note that PRB-1 does not cover covenants although there is a brief mention of covenants in the 1999 PRB-1 clarification. Unfortunately, the FCC has not yet provided an outright preemption of covenants for amateurs.

The FCC may impose limited quiet periods on the amateur station on those frequencies involved. Conversely, the amateur station must be operating properly without violating any rules especially regarding spurious emissions.

Hint: Long question, long answer. Silly hint: Correct answer does not include the phrase "must cease".

You must first register with the local civil defense organization and then at that point you can register your amateur radio station with RACES. Each operator must follow the operator privileges granted by the license.

§ 97.407 Radio amateur civil emergency service.

(a) No station may transmit in RACES unless it is an FCC-licensed primary, club, or military recreation station and it is certified by a civil defense organization as registered with that organization, or it is an FCC-licensed RACES station. No person may be the control operator of a RACES station, or may be the control operator of an amateur station transmitting in RACES unless that person holds a FCC issued amateur operator license and is certified by a civil defense organization as enrolled in that organization.

Hint: Civil defense

Silly Hint: You have to be Responsible for RACES

The frequencies that may be used are determined by the control operator's license. Normally RACES stations will communicate with other RACES stations but other stations may be authorized by a responsible civil defense authority.

PRB-1 is a legal document from the FCC that requires that local governments reasonably accommodate Amateur Radio installations.

According to the ARRL PRB-1 web page:

The FCC's PRB-1 document, an 11 page Amateur Radio Memorandum Opinion and Order, was released September 19, 1985. Even though it is from 1985, it is still valid today. The legal cite is 101 FCC 2d 952 (1985) and it can be found on the FCC Web page.

See the whole document on ARRL's web site here.
