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.

02/20/25 Question:  From History Facts (.com)

In shadow of Presidents day, here is a little known fact. When the Lincoln Memorial was dedicated on May 30, 1922, the world bore witness to how $2,000,000 (more than $36 million today) in federal funds, eight years of American elbow grease, and 38,000 tons of marble, granite and limestone could result in something truly extraordinary: A very, very expensive typo.

The misspelled word was:

• A) RAISEN – (REASON)
• B) EUTURE – (FUTURE)
• C) INAUGERAL – (INAUGURAL)
• D) INSERGENT (INSURGENT)

Answer: B) EUTURE – (FUTURE)

On May 30, 1922, the Lincoln Memorial was dedicated in a grand ceremony on Washington, D.C.’s National Mall. The project was an incredible investment, costing around $2 million to build (more than $36 million today). Construction lasted eight years and required 38,000 tons of marble. Despite all the time and effort, one mistake went unnoticed: The word “FUTURE” was accidentally etched into the marble as “EUTURE.” The error is found in the text of Lincoln’s second inaugural address, which is carved into the north wall of the monument. The extra line was corrected, but the slightly off-colored stone is still visible today.

Discussion: 

1: The four prominent U.S. Presidents carved into Mount Rushmore were chosen by sculptor Gutzon Borglum to represent major milestones and ideals in American history. George Washington, the first President, was chosen as a symbol of the birth of the nation;

2: Thomas Jefferson represents the expansion of the country through the Louisiana Purchase;

3:Abraham Lincoln was picked for his role in preserving the union;

4: Theodore Roosevelt symbolizes the nation’s industrial growth. While all of these famous figures are known for their pivotal roles in the country’s history, there’s much more to each of their stories. Here are six interesting facts about the Mount Rushmore Presidents.

03/20/25 Question:  For an EME (earth-moon-earth, or "moonbounce") transmission, the best position for the moon to be in is:

• Choices:
• A: Farthest from the earth,
• B: Closest to the earth,
• C: On the horizon,
• D: Directly overhead

Answer: B) Closest to the earth

(Because signals are weak, and the distance is great, the closer the moon is to the earth should result in a stronger "reflection" of the signal.)

1. Earth-Moon-Earth (EME), also known as "moonbounce," is a radio communication technique where radio waves are transmitted from Earth, bounce off the Moon, and are received back on Earth, enabling long-distance communication. 

• How it works:

EME utilizes the Moon as a passive reflector, allowing radio signals to travel beyond typical line-of-sight distances. 

• Challenges:

The Moon is a poor reflector and is located far away (about 240,000 miles or 384,000 km), which means the signal is very weak and requires specialized equipment and techniques. 

Equipment:

EME requires high-gain antennas (like Yagi or dish antennas), low-noise preamplifiers, and powerful transceivers

• Propagation Factors:

Signal propagation is affected by factors like Doppler shift, libration (the Moon's wobble), and Faraday rotation (the Earth's magnetic field affecting signal polarization). 

• Frequency Bands:

Amateur radio EME operations are typically conducted on VHF and UHF bands, including 2 meters (144 MHz), 70 cm (432 MHz), and microwave bands. 

• Digital Modes:

Digital modes like WSJT-X are commonly used for EME communication, as they are more robust and efficient in weak signal conditions. 

• History

The first two-way amateur QSO via the moon took place in 1960.
