What is Morse Code?

The specific typing method of the Morse code is shown in the figure of this article. Morse code uses only zero and binary systems of one or two states**, and it includes five types: short dot signals" "read" drop "(di) long signals that hold for a certain amount of time"—"read "da" for pauses between dots and strokes, medium pauses between each word, and long pauses between sentences.

There are three additional signals to remember and use:

Always remember to use the "Start" signal before communicating

If an error occurs during the communication, a "wrong" signal should be sent before the correct signal is transmitted.

At the end of the communication, be sure to add a "end" signal".

A password for passing information.

1. Morse code (also translated as Morse code, Morse code) is a kind of time-on and intermittent signal**, which expresses different English letters, numbers and punctuation marks through different sequences.

2. Morse code is an early form of digital communication, but it is different from the modern binary that only uses zero and one or two states, and it includes five types: dots, strokes, pauses between dots and strokes, short pauses between each character, medium pauses between each word, and long pauses between sentences.

Tapping out the Morse code with your finger first requires understanding the rules of passwords. Morse code is made up of two basic signals with different intervals: short dot signals"·", read"Drops"(di)and long signals that are maintained for a certain period of time"-", read"Click"(da)Compose.

The Morse code can't make two sounds by hand, but it canReplace the ticking sound with the nails and belly of the fingers to make a more sharp sound and a more muffled sound.

Generally speaking:

The interval time is a short dot signal"·"The drop is 1t.

Hold a long signal for a certain period of time"-"Click"(da) is 3t.

The interval between drops and clicks is 1t.

The interval between the characters is 3t.

The interval between words is 7t.

The original Morse code relied on a telegraph operator to strike out dots, strokes, and pauses in between.

Code Classification: The International Morse Code is still used today, even though it has become almost exclusively the preserve of radio amateurs. However, it was not until 2003 that the International Telecommunication Union (ITU), which administers Morse code proficiency around the world, obtained amateur radio license jobs.

Amateur radios are still reserved by some countries to transmit Morse code signals.

Because Morse relies only on a smooth, invariant radio signal, its radio communication equipment is simpler than other methods, and it can also be used in high-noise, low-signal environments.

At the same time, it requires a very narrow bandwidth and is able to facilitate communication between two operators who speak different languages and have great difficulties in communicating on the phone. However, this is the most commonly used form of QRP.
