Radio Transmissions facts

While investigating facts about Radio Transmissions From Space and Radio Transmissions Are Highly Secure, I found out little known, but curios details like:

The Eiffel Tower was supposed to be scrapped after 20 years. It only survived because the military started using it as a radio tower, intercepting crucial military transmissions during World War I.

how do radio transmissions work?

There is a "Quiet Zone" in the United States where radio transmissions are restricted, and microwave ovens, wifi routers, and cell phones are prohibited.

What marketing technique used am/fm radio transmissions?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what authority has jurisdiction over radio transmissions. Here are 37 of the best facts about Radio Transmissions From The Past and Radio Transmissions Subnautica I managed to collect.

what are radio transmissions?

1. During a critical moment in the Apollo 13 mission the Soviet Union discontinued radio transmissions in the frequency bands used by Apollo to prevent radio interference

2. John Lennon's comment 'More popular than Jesus' created a huge backlash in the US Bible belt, with one Texas radio station holding a large bonfire of Beatles albums only for a lightning bolt to strike its transmission tower the following day and sending the station temporarily off the air.

3. The phrase "A-OK" originated from NASA engineers who used it during radio transmission tests because "the sharper sound of A cut through the static better than O"

4. Since 2004, Yosemite Sam has been exclaiming "Varmint, I'm a-gonna b-b-b-bloooow yah t'smithereenies!" continuously on a range of shortwave radio frequencies. Reports indicate the transmission may come from Albuquerque.

5. 'A-ok' originated during NASA radio transmission tests because the sound of the letter 'A' cut through radio static better than the sound of 'O'

6. Scientists have twisted radio beams to send data. Transmissions reach speeds of 32 gigibits per second. For reference, 32 gigabits per second is fast enough to transmit more than 10 hour-and-a-half-long HD movies in one second and is 30 times faster than LTE wireless.

7. There is a quiet zone located in Virginia and West Virginia, nearly 13,000 square miles in size, where radio transmissions are strongly restricted by law, to the point of having a patrol that goes around and forces you to shut off anything that emits radio waves.

8. Green Bank, West Virginia, home to the "National Radio Quiet Zone" whereby radio transmissions are are mostly outlawed for 13,000 square miles to reduce interference with one of the world's largest telescopes. They even have their own "Radio Police" who enforce these laws.

9. In 1977, a radio signal, called the "Wow!signal" was detected from interstellar space . It bore the expected signs of extraterrestrial origin and till today, no hypothesis have been able to explain it adequately. It was dubbed the strongest candidate for an Alien transmission ever detected.

10. The first ever in-flight radio transmission was "Roy, come and get this goddamn cat!"

Why does ionosphere affect radio transmission?

You can easily fact check it by examining the linked well-known sources.

In 1977, a 72-second interstellar radio transmission from the constellation Sagittarius was recorded by an observatory in Ohio. It has never been recorded again, and scientists still have no idea where it originated.

There is a 13,000 square mile area spanning over Virginia, West Virginia and Maryland called the National Radio Quiet Zone in which cell phone usage and radio transmissions are heavily restricted. - source

The "United States National Radio Quiet Zone." A 13,000 square mile area of Virginia, W.Virginia and Maryland wherein all radio transmissions are heavily restricted for scientific research and military intelligence. - source

Some of the very first air-to-ground radio transmissions were from the airship "America", and made about the ship's cat, Kiddo, in 1910. "Come and get this goddamn cat!" - airship engineer Melvin Vaniman.

The word “Broadcast” was originally used to describe the spreading, or casting, of seeds by hand. It wasn’t until 1921 that it was used to describe radio transmission. - source

When are voice transmissions not made on radio beacons?

In 1973 a California radio operator received a transmission from a young boy, "Larry," who was stuck in an overturned truck. An extensive search was launched, but Larry refused to give his last name or whereabouts, and was never found

How fast do radio transmissions travel in space?

In 1969 a HAM radio operator in Louisville Kentucky listened to the Apollo 11 transmissions from the the moon on home built equipment. He verified that the transmissions were not edited for TV broadcast, and verified they were coming from the moon. A fact overlooked by the moon hoax nut-jobs.

One of the first ever Air to Ground Radio transmissions was "Come and get this goddam Cat!".

"Roy, come and get this goddamn cat" was the first in-flight radio transmission. In the end, the cat found itself stuck on the ship after a failed retrieval attempt in a canvas bag dangling from a rope.

In 1937 then-15-year-old Betty Klenck possibly picked up an emergency radio transmission from famously-missing Amelia Earhart who appeared to have crashed-landed somewhere. To this day, her body was never recovered/identified.

Live many radio and TV transmissions are broadcasted with some delay in order to allow to technicians to intervene if someone in the transmission do something wrong.
