Morse Code
Although cellphones and SMS have pretty much made Morse Code moribund - its most popular current use is probably by amateur radio operators - this is a sub-category dedicated to the dots 'n dashes of the code that was invented by Samuel F.B. Morse in 1838. Find out "What is the most famous distress signal in Morse Code?" or "How do you communicate using Morse Code?

How did Morse code effect life in a bad way?
Truth is, Morse Code didn't effect society in a bad way and if it did...... There would be a good reason for it.
What are the differences between the Morse code and the semaphore code?
- Morse code is transmitted electrically over a wire using a key and sounder, it can go anywhere you can run the wire and for thousands of miles. It can also be transmitted by radio and go around the world and into outer space.
- semaphore code is transmitted visually by waving flags in various angles and viewing them either directly or with a telescope, it is line of sight only with a maximum range of perhaps 20 miles in ideal conditions
How are the the letters represented in Morse code?
Letters, digits, punctuation marks, and special codes (i.e. characters) are represented by sequences of short and/or long pulses separated by short gaps. Short pulses are called dots and pronounced as "di" except at the end of a character, where they are pronounced as "dit". Long pulses are called dashes and are pronounced as "dah". Characters are separated by long gaps.
Why didn't people have Samuel Morse's telegraph in their homes?
There are two main reasons:
- not everyone would be willing to learn the Morse code needed to operate it (it is effectively a different language that must be learned by "ear" and practiced extensively; this was and is the main roadblock).
- telegraphs were easy to connect point to point but not into the complex network that would be needed to support home telegraphs.
But initially even the telephone was rare in homes as the service charges were quite high.

Many do, even today. We're called "Hams", or "amateur radio operators".
It never became as widely used as, for example, the telephone, because learning to key and understand the Morse code is effectively learning another language. It takes a couple of months of steady practice to get good at it, and you need to keep doing it to maintain that skill level.
Today, "ham" radio operators operate networks that carry free radio messages to and from ships, to remote military locations, and to the sites of natural disasters.
The "continuous wave" or CW telegraphy doesn't require much power, and the equipment is easily portable. Every spring, clubs of Ham operators participate in "Field Day", in which they set up their radios and antennas in parks, back yards, and other places to practice contacting other clubs doing Field Day activities.
The expansion of the internet has decreased the interest level in amateur radio, but it's fairly easy to learn, even for children. The youngest Ham I ever knew got her license at age 7.
How did Samuel Morse's invention change communication in the US?
it allowed people to send messages almost instantly (NovaNet)
Do people use the Morse code today?
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.
Is the Napoleonic code still used today?
Yes, but only in the state of Louisiana and other countries.
There is no full for SOS, but it is a distress signal in the Morse code, which goes like this : (· · · - - - · · ·)
What is the fullform of s.o.s call?
SOS does not actually stand for anything. The letters were chosen because of their simplicity (three dots and three dashes)
The words Save Our Souls or Save Our Ship have simply been associated with them.
Morse is capitalized because it is the name of the system. Also, Morse is the name of the person who invented the system.
What does dsa on your volva dash mean?
If you mean a VOLVO ....
Dynamic Stability Assistance
Your car can be fitted with Dynamic Stability Assistance (DSA). This is a system that helps prevent wheel spin. It comes on automatically each time you start the car. It operates automatically at all speeds if one or both driven wheels start spinning. The ABS sensors tell the engine management system that the wheels are turning at different speeds. The engine management system then reduces power to the engine via the fuel injectors in 16 steps until no further wheel spin occurs.
How do you use morse code on a flashlight?
To use Morse code with a flashlight, turn the flashlight on and off to represent the dots and dashes of the code. A short flash (dot) is typically 1 unit of time, while a longer flash (dash) is 3 units. Make sure to leave a brief pause (about 1 unit of time) between dots and dashes and a longer pause (about 7 units) between letters and words. This way, you can effectively communicate messages in Morse code using light signals.
3 dots mean the letter 'S' in Morse code. The classic way of remebering this is the phrase "SOS" which is 3 dots followed by 3 dashes and then 3 more dots.
What is the dot and dash sign for SOS?
S O S :
. . . / _ _ _ / . . .
Letter S: ( . . . )
Letter O: ( _ _ _ )
SOS is correctly transmitted as one morse character (no character gaps) not three individual characters.
. . . _ _ _ . . .
How do you speak in Morse code?
To speak in Morse code, you can use short and long signals to represent individual letters or numbers. For example, a short signal (dot) represents the letter 'E' and a long signal (dash) represents the letter 'T'. By combining these signals in the correct sequence, you can spell out words and sentences in Morse code.
What dot dot letter gets a 'C' sound in Japanese?
You probably mean kana with diacritical marks.
What you mean by 'c sound' is unclear. In Japanese the 't' column reads like this
ta
chi
tsu
te
to
If you mean the 'kuh' C sound (as in cookies) you would use the 'k' line of kana:
ka
ki
ku
ke
ko
If you mean the 'suh' sound (as in cereal) you would use the 's' line:
sa
shi
su
se
so
Adding ten ten to any of these characters will not give you a 'c sound.'
