Respective rating used to report ballpark signal strength and clarity of a transmission. So a 5 by 1 means a strong signal is present, but what is saying cannot be understood. 1 by 5 means you can understand them, but a signal is barely coming in. 5 by 5 is ideal for both counts.

Can also be used nowadays to mean one is doing well.

Ex. A) – command to alpha2IC, do you read?
-command this is alpha2IC, I got you 5 by 5.

b) How’s it going?
I’m 5 by 5.
