Question

What does the term "5 x 5" mean and where does it come from?

Answer 1

It means 5 wide and 5 deep. It is used in packing terms for food manufactures for example: 5x5 tomato would be 5 rows wide and 5 rows deep would yield 25 tomatoes this also represents the size of the tomato for the box, they fit perfectly in the box.

There may be other terms, this is just what I know about.

Hope this helps

Answer 2

5 by 5

This is an old aeronautical radio term. Radio signal strength and clarity were measured on a scale of 1 to 5. Today the term "Loud and Clear" is preferred to "5 by 5".

Have fun but be safe.

Answer 3

The 5x5 radio answer to a calling station from a receiving station is as old as the "roger willco" answer dating back to the 2nd world war. They have long since gone in to history and are seldom heard on the bands any more. The 5x5 was replaced at one time with "5 square", but even that has gone the way of the DODO bird. It was to tell the other station that you heard them "loud and clear".

With CW it was sent as 5x5, with voice it was "5 by 5".

Answer 4

Radio signal quality is reported on two scales; the first is for signal strength, and the second for signal clarity.

Both these scales range from one to five, where one is the worst and five is the best.

The listening station reports these numbers separated with the word 'by'.

Five by five therefore means a signal which has excellent strength and perfect clarity - the most understandable signal possible.
