My second daughter said that "Ryoukai(accepted)" is abbreviated as "Ri".

I am a senior, but I do not feel resistant to this abbreviation.

Rather - affirmation.

Why?

I got an amateur radio license when I was an elementary school student, and after that I also owned the qualification of a telegraph class (Morse code).

When there was no shadow of the Internet, for the ordinary people, only the amateur radio was released to the world.

Among them, telegraphy is a very simple communication format ("- ・ ・" only with sound), which makes it possible to earn transmission distances.

Needless to say, it is very important in telegraph "how short we can make that message".

For example, Calling any station -> CQ.

"Could you please move up three kilo hertz for our channel" → CUD U MOVE UP 3 ?

I could use these abbreviations in telegram.

Believe it or not, it is the fact that "Japanese primary school students and junior high school students" have exchanged such English messages with overseas people.

This is because the pattern of telegrams in amateur radio is finite and it was stylized like a haiku.
