ROGER! Your Essential Guide to Radio Codes

"Copy that!" "Roger!" These radio lingoes are already familiar to both radio and non-radio operators because they're so prevalent in modern songs and movies. But have you scratched your head when heard other shorts, such as "what's your 20", or just "10-20"? If YES, then this article would be helpful.
1. Why Do We Recommend Radio Codes?
Most of the time, the audio quality of two-way radio is lower than our smartphones. If you keep speaking the whole sentence like usual, some of your words may be lost in radio transmission. Using common radio codes, lingoes, or just call "walkie-talkie language", would make messages shorter but right. That's why radio talk codes are now popular in military, civilian pilots, and a lot of indoor and outdoor usage.
