What is A1?
As you know well in case of radio.
According to the Japanese Radiowave Regulation, "A1" is defined as follows;
carrier amplitude modulated telegraph without using voice frequency for modulation.

In other general meaning in Europe, "A-1" means "the very best".
Origin of this meaning is a marine insurance company in London.
This company specified "vessel inspection rank" which shows condition of the vessel and its cargo.
The rank of vessel is indicated by alphabet and the rank of cargo is indicated by figure.
"A" means that the vessel is perfect.
"1" means that the cargo is perfect.
