Subelement E1 COMMISSION RULES Section E1B

Station restrictions and special operations: restrictions on station location; general operating restrictions; spurious emissions; antenna structure restrictions; RACES operations

Which of the following constitutes a spurious emission?

An amateur station transmission made without the proper call sign identification

A signal transmitted to prevent its detection by any station other than the intended recipient

Any transmitted signal that unintentionally interferes with another licensed radio station

Correct Answer

An emission outside the signal's necessary bandwidth that can be reduced or eliminated without affecting the information transmitted

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.

Which of the following is an acceptable bandwidth for Digital Radio Mondiale (DRM) based voice or SSTV digital transmissions made on the HF amateur bands?

Correct Answer 3 kHz 10 kHz 15 kHz 20 kHz

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

-benny2

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

Answer: 3KHz -KE0IPR

Within what distance must an amateur station protect an FCC monitoring facility from harmful interference?

Correct Answer 1 mile 3 miles 10 miles 30 miles

§ 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.

What must be done before placing an amateur station within an officially designated wilderness area or wildlife preserve, or an area listed in the National Register of Historic Places?

A proposal must be submitted to the National Park Service

A letter of intent must be filed with the Environmental Protection Agency

Correct Answer

An Environmental Assessment must be submitted to the FCC

A form FSD-15 must be submitted to the Department of the Interior

You only need to work with the FCC. Go to their website www.fcc.gov and search for "Environmental Assessment" and the forms will be listed.

What is the National Radio Quiet Zone?

An area in Puerto Rico surrounding the Arecibo Radio Telescope

An area in New Mexico surrounding the White Sands Test Area

Correct Answer

An area surrounding the National Radio Astronomy Observatory

An area in Florida surrounding Cape Canaveral

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

(32) 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.

page 589

From Wikipedia:

The United States National Radio Quiet Zone is a large area of land surrounding the National Radio Astronomy Observatory (NRAO) at Green Bank, West Virginia, and especially the large Green Bank Telescope radio telescope. The Radio Quiet Zone is a rectangle of land approximately 13,000 square miles (34,000 km2) in size that straddles the border area of Virginia and West Virginia. It includes all land with latitudes between 37.5°N and 39.25°N and longitudes between 78.5°W and 80.5°W. This area was chosen because it has a hilly topography that screens out most incoming radio signals, allowing the Green Bank telescopes to receive signals that are otherwise too low in power to be heard over the normal radio background in North America.
