Trivia Question Etiquette

Trivia questions are multiple-choice. If unsure, it's okay to guess! If you know the answer, no explanation is needed - it makes things less fun for those after you.

After the correct answer is revealed, sharing related facts or personal stories is encouraged, but save detailed discussions for the end of the session. Let the Net Control know if you have extra information to share afterwards.

Past Trivia / Discussion Questions

07/25/24 Question: In what country is there a credible claim of powered flight before the Wright brothers?

08/01/24 Question: In order to earn the ARRL DXCC award, a station must confirm 2-way contact with a minimum of:

• A: 100 Countries
• B: 100 DX Entities
• C: 100 Zones
• D: 100 Grids
• Correct Answer: 100 DX Entities

(An applicant for the DXCC award must submit confirmed two-way contacts with 100 or more different DX entities. Yes, the ARRL certificate says "Countries" but Alaska and Hawaii are not countries! A DX entity may in fact be a country or it may just be a part of a country (an island, a reef, etc. that's part of a country))

08/08/24 Question: What does the term 'twisted pair' mean in as it relates to wire?

• A: It's a method used to help overcome hum and crosstalk in long wire runs
• B: It's a method of introducing a required inductance in a tuned circuit
• C: It's a means of inducing stray capacitance into CW transmitter wiring to help prevent chirp
• D: Describes an impedance flaw with balanced feeder lines
• Correct Answer: It's a method used to help overcome hum and crosstalk in long wire runs

(Answer 3 was pretty much a restating of answer 1 so I rewrote #3 -Dave W7UUU Reduces hum and crosstalk in communications lines: https://en.wikipedia.org/wiki/Twisted_pair Originated from the days when phone company telephone wire pairs were twisted around one another to reduce hum pickup, crosstalk, and other unwanted noises and interference.)

08/15/24 Question: When was the largest geomagnetic storm that occurred?

• A) 1859
• B) 1882
• C) 1921
• D) 1960
• Answer: A) 1859

On September 1–2, 1859, the largest recorded geomagnetic storm occurred. From August 28 until September 2, 1859, numerous sunspots and solar flares were observed on the Sun, with the largest flare on September 1. This is referred to as the solar storm of 1859 or the Carrington Event.

08/22/24 Question: Trivia Question: As a colloquial term the 6M is often referred to as what kind of band:

• A: Sit and wait band
• B:Good Neighbor Band
• C: Magic Band
• D: Tech Class HF Band
• Answer: C- The Magic Band

08/29/24 Question:: In what year did the first Field Day occur?

• a) 1915
• b) 1921
• c) 1933
• d) 1938
• Answer: c) 1933

The highest score was 98 contacts, submitted by W9ZZAL, the Central Illinois Radio Club. The odd 1x4 call
sign and a suffix starting with ZZ was a special call sign required by the FCC to be issued specifically for portable operation.
Back then Field Day started at 4PM Local Time. (No DST in those days)

09/05/24 Question:: Why do the British and other “crown” countries drive on the left while most countries drive on the right?

• To be able to draw and use a sward
• To make it easier to mount a horse.
• Reduce the possibility that someone may grab your weapon
• All of the above
• None of the above
• Answer: D) All of the above

Why do some countries drive on the left and others on the right?

09/12/24 Question::

What sets Wi-Fi 6E and Wi-Fi 7 apart from previous generations of Wi-Fi?

• A) Encryption
• B) Multi-Link Operation (MLO)
• C) 5 GHz operation
• D) 6 GHz operation

Answer: D) 6 GHz operation
Prior generations of Wi-Fi use encryption, Multi-Link Operation (MLO) is specific to Wi-Fi 7, the 5 GHz band has been in use for a few generations, and the new 6 GHz band is only available on Wi-Fi 6E and 7.

09/19/24 Question: Center-fed half-wave dipoles in free space have an input impedance of approximately:

• A: 37 ohms
• B: 50 ohms
• C: 73 ohms
• D: 100 ohms
• Correct Answer: c) 73 ohms

(A true half-wave dipole is one half of the wavelength ? in length, where ? = c/f in free space. Such a dipole has a feed point impedance consisting of 73 ? resistance and +43 ? reactance, thus presenting a slightly inductive reactance.) From QRZ Quiz 09/19/24

09/26/24 : Hurricane Helene is in the Gulf of Mexico heading north to Florida and Georgia. Hurricane nets are scheduled Thursday morning thru Friday morning.

• 40 meters: 7.268 MHz (LSB) at 10:00 AM EDT (1400 UTC). The net will remain active on this frequency throughout the day and overnight for as long as propagation allows. If propagation allows us to operate all night, we will suspend operations at 7:30 AM EDT Friday to allow the Waterway Net to conduct its daily net.
• 20 meters: 14.325 MHz (USB) at 10:00 AM EDT (1400 UTC) until losing propagation at night.

Question: taken from History facts. 

Before the 20^th century IN THE US, hurricanes were named after”

1. Patron saints (West Indies)
2. Characters from Greek and Roman mythology (19^th Century British Meteorologist clement Wraggs)
3. The last name of political enemies
4. Named after women (nobody ever heard of a himmacane)
5. There was no uniform method for naming hurricanes

Answer: E- No uniform method for naming hurricanes.

Before the 20th century, there was no uniform method for naming hurricanes in the U.S., though some other parts of the world saw creative naming conventions. Residents of the West Indies, for example, named hurricanes after patron saints. And 19th-century British meteorologist Clement Wragge used characters from Greek and Roman mythology, as well as the last names of his political enemies, for typhoons in the Pacific Ocean. He also began a tradition that eventually made its way across the Atlantic: using women’s names for hurricanes.

Until the 1940s, hurricanes in the U.S. were generally referred to simply by the year and/or place they occurred, such as the “Great Miami Hurricane of 1926.” That changed during World War II, when Navy and Air Force meteorologists began to name the tropical storms they tracked after their girlfriends and wives for easier reference. For a time, the U.S. military also experimented with naming storms after its phonetic alphabet — Able, Baker, Charlie, and so on — but this was replaced with a system thought to be less confusing and easier for the public to remember. In 1954, the National Weather Bureau chose to use women’s names as the standard for hurricanes; that year saw Alice, Barbara, Carol, and others. 

But why women’s names, specifically? The decision was partially inspired by the trend that began during the war, though it was also rooted in sexist stereotypes about the temperamental nature of women. The practice continued in the U.S. until the 1970s, when members of the women’s movement spoke out against the negative characterization of women that pervaded every facet of society, including storm-naming. In 1979, the National Weather Service and the World Meteorological Association changed the naming convention to include an even split of women’s and men’s names, using six groups of 26 names that rotate annually. https://historyfacts.com/science-industry/fact/hurricanes-used-to-only-be-named-after-women/
