Yes, but almost completely as a hobby (ham radio).
A2. For communicating with submerged submarines, use is made of Very Low Frequencies, <20kHz. Radio waves at these frequencies can penetrate into the ocean.
The only modulation practical at these carrier frequencies is necessarily some form of pulse code.

What does -.- mean?
"-.-" Is a computer smiley. People use it when they are annoyed or mad."-.-" If you look at it closely you can see 2 eyes and a nose.Answer-.- is Morse code for the letter k.
How does Morse code work and what is it?
Morse code - is an internationally recognised signalling system. Each letter, number and punctuation mark is represented (on paper) by a series of dots and dashes. a dot represents a short 'tone' - and a dash represents a long tone. The most recognisable morse code 'phrase' is SOS.... which is sent as . . . _ _ _ . . . (dot dot dot dash dash dash dot dot dot).
What did Alfred Lewis Vail do?
Alfred Lewis Vail was an American inventor and associate of Samuel Morse, best known for his contributions to the development of the telegraph. He played a crucial role in improving Morse's telegraph system by enhancing the design and creating the Morse code that we recognize today. Vail also developed the first commercial telegraph system in the United States, significantly advancing long-distance communication. His innovations laid the groundwork for the widespread use of telegraphy in the 19th century.
How are Aristotle's teaching related to the scientific method used by scientists today?
He urged people to use their sences to make observations, just as scientist today make observations
What did the Romans make that you still use today?
The Romans actually invented concrete! We still use that today. They also invented roads. The Roman people invented the making of wine and how to do it. Romans had and used libraries and the building design of Roman buildings are still in use today.
What was the first year people started to use Morse code?
The first year people started to use Morse code was 1844.
You use dots and dashes in code?
you use dots and dashes in the Morse code
What animals use Morse code?
The acquisition of an ability in Morse Code is a significant accomplishment for most people, just as any other representational language. Animals don't use it.
What is the code that people use to trasmit messages by sending electrical pulses?
It is called Morse code.
How many people use Morse code around the world?
It's difficult to determine an exact number of people who actively use Morse code today, as its use has significantly declined with the advent of modern communication technologies. However, it is estimated that a few thousand enthusiasts, including amateur radio operators and hobbyists, still practice and utilize Morse code regularly. Additionally, it remains a valuable skill in certain niche applications, such as aviation and emergency signaling.
When the Morse code invented?
A character code invented by Samuel Morse it is called the Morse code and it was invented in 1844. It was replaced by a simplified International Morse Code that is easier to use in 1865.
How did Morse code benefit people?
They could send messages using it by telegraph and ships used it. If you know Morse code you don’t have to say anything, but can use lights to send the dots and dashes that make up Morse code.
Why did they use Morse code?
At the time, Morse code was by far the easiest way of communication.
How long has Morse Code been used for?
It has been used once circa 1835 and is still in use today.
Where exactly is the Morse code in Wii Sports Resort Island Flyover?
There are three different messages which are cycled. #1: Morse code takes forever. It sure does. #2: Does anyone out there know Morse code? Sorry. Use your radio. Yes, people are still chatting away in Morse code. Check out http://www.arrl.org #3: Why does anyone use Morse code anymore? Good question. It's cheap and efficient. It gets through in bad conditions. In fact some aviation beacons are in morse.
Is Morse code global?
The modern International Morse Code, introduced in the 1860s is global. However its actual use is declining. Morse's original code, introduced in the 1830s was mostly limited to the US. The European Morse Code, first introduced in Germany in the 1840s was mostly limited to Europe. The International Morse Code was derived mostly from the European Morse Code and is much simpler and easier to use than Morse's original code.
Is a Morse Code machine still used today?
Morse code is still in use if you know where to look. Many ham radio operators around the world converse with "CW" (Morse code) on a regular basis. Listen around on a shortwave radio with "SSB/CW" capability for a little while and you'll hear lots of Morse code.
