What is Five-by-Five (Good Copy Signal)?

We are often asked what 5X5 stands for. The proper pronunciation for our name is 5 BY 5. As with our business model, our name has its history in military service.

The term 5X5 is rooted in the communications within military forces through WWII to mean "I understand you perfectly." The first number represented the Signal Strength of a radio communication, and the second number represented the signal clarity on a scale from 1-5 -- 1 being the worst; 5 being the best. Therefore 5 by 5 means the signal has excellent strength and perfect clarity - the most understandable signal possible. Five by five is the predecessor to the term "Loud and Clear" or "Lima/Charlie" used by military units today.
