ELI5: Explain Like I'm 5

PSK63

Okay kiddo, have you ever played with walkie-talkies? Well, PSK63 is a special type of communication that lets you talk to people using a computer instead of a walkie-talkie. PSK stands for Phase Shift Keying, which is a way of sending information in a special language using sound waves.

Now, imagine you have a secret code that you want to send to your friend. You can type it into the computer in PSK63 language, and the computer will turn it into a sound that's sent over the radio waves. Your friend's computer can then pick up that sound, decode it using the same PSK63 language, and read your secret message!

It's like a secret language that only people with the right computer and radio equipment can understand. But don't worry, it's not just for spies - PSK63 is actually used by ham radio operators around the world to chat with each other!
