5x5

Twenty-five cells

Five by five means loud and clear, from radio signal strength ratings where the first number indicates strength (1-5) and the second indicates clarity (1-5).

Maximum on both scales means perfect reception.

The phrase extends to mean everything's fine or going well: How are you holding up? —Five by five.

Common in military, aviation, and trucker radio communications.
