Signal strength and readability are measured on a five point scale with 5 being the highest value possible and 1 being the lowest. So when you say to the controller (or pilot) “5 by 5”, it is literally another way of saying that the transmitter you hear is “loud and clear.”

What is 5 by 5 signal strength and readability?
Signal strength and readability are measured on a five point scale with 5 being the highest value possible and 1 being the lowest. So when you say to the controller (or pilot) “5 by 5”, it is literally another way of saying that the transmitter you hear is “loud and clear.” If you say “3 by 5” it’s like saying,...
What does five by five mean on a cell phone?
However, the "five bars" displayed on many cell phones does directly correlate to the signal strength rating. The phrase "five by five" can be used informally to mean "good signal strength" or "loud and clear". An early example of this phrase was in 1946, recounting a wartime conversation.
How do you reply to thanks for hearing me?
Depending on the situation and the person we must reply accordingly. Thank you! (Formal, with respect, to Superiors or Elders) Good to hear from you too. (Mutual, formal, to anyone) The feeling is mutual. (informal, Flirty, to a friend) Thanks for hearing me (informal, sarcastic, to a friend)
How do we hear sound?
How Do We Hear? Hearing depends on a series of complex steps that change sound waves in the air into electrical signals. Our auditory nerve then carries these signals to the brain. Also available: Journey of Sound to the Brain, an animated video.

Informal terminology and slang The phrase "five by five" can be used informally to mean "good signal strength" or "loud and clear".
What does it mean when someone says five by five?
I understand you perfectlyThe 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.
What does it mean when a pilot says 5 by 5?
It does not mean yes; it just means, “I heard you.” It's also important to remember than anyone using a radio frequency can key the mic and talk, so there isn't any way to identify the speaker. That's why radio communications always include the aircraft's call sign or the flight number.
Where does the saying 5x5 come from?
Etymology. From radio communications phrase dating from the 1950s. The first five referred to a rating of signal clarity, the other to reception strength. See Signal strength and readability report.

“OK10-4 is an affirmative signal: it means “OK.” The ten-codes are credited to Illinois State Police Communications Director Charles Hopper who created them between 1937–40 for use in radio communications among cops. Ten-Four Day ~ for decades, Oct 4 has been a day to salute radio operators.
How do you respond to a comms check?
Response to "Radio Check". Means your transmission signal is good. Also, use "Read you 5-by-5". You are asking the other party to acknowledge they hear you.
What is rst in ham radio?
The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an assessment of the signal's readability, strength, and tone.
What does it mean when someone says 5 out?

ERP & EIRP Calculator – M0UKD – Amateur Radio Blog
The Effective Isotropic Radiated Power (EIRP) is the apparent power transmitted towards the receiver, if it is assumed that the signal is radiated equally in all directions, such as as a spherical wave emanating from a point source; in other words, the arithmetic product of the power supplied to an...
"In the pipe five by five" - Here is what it actually means
Today, we’ll be talking about one that in all likelihood, you’ve probably not heard too often. “In the pipe, five by five”. If you get the feeling that you recognise it, but can’t put your finger on where, the answer is the probably the film ‘Alien’.

Jerry on Aug 24, 2011. So I don’t remember where I read this, but I read that five by five was just a slang term used to mean loud and clear was used by either a British or French pilot years and years ago (spelling loud, “Loude”) thus the term mearly refrenced the words.
What does the first five mean?
The first five relates to the clarity, how clear the signal is. Five out of five. There is no static noise, and you can clearly hear what’s being said to you. The second five is about the volume.
Where does the 5 by 5 come from?
It originates from the navy where it means that your aim is clear for reaching the ship you want to hit, and the five by five part comes from the radios in the navy. Many of us will only ever have heard it in the phrase in the film Alien. It hasn’t been used by many people.
What does 5 by 5 mean?
The phrase "five by five" can be used informally to mean "good signal strength" or "loud and clear". An early example of this phrase was in 1946, recounting a wartime conversation. The phrase was used in 1954 in the novel The Blackboard Jungle. Another example usage of this phrase is from June 1965 by the crew of the Gemini IV spacecraft. This phrase apparently refers to the fact that the format consists of two digits, each ranging from one to five, with five/five being the best signal possible.
What is a radio signal strength and readability report?
A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their radio station equipment.
Why is the signal quality of a digital signal cliff?
This is because digital signals have fairly consistent quality as the receiver moves away from the transmitter until reaching a threshold distance. At this threshold point, sometimes called the " digital cliff ,"the signal quality takes a severe drop and is lost".
What is the move to plain language radio?
The move to plain-language radio communications means that number-based formats are now considered obsolete, and are replaced by plain language radio checks. These avoid the ambiguity of which number stands for which type of report and whether a 1 is considered good or bad.
What causes the cochlea to ripple?
Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. Hair cells—sensory cells sitting on top of the basilar membrane—ride the wave. Hair cells near the wide end of the snail-shaped cochlea detect higher-pitched sounds, such as an infant crying.
Where does sound travel through the ear?
Also available: Journey of Sound to the Brain, an animated video. Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and ...
What are the three bones that vibrate in the middle ear?
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes . The bones in the middle ear amplify, or increase, the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid, in the inner ear.
What is the frequency response of a speaker?
The range of human hearing is generally regarded as being from 20Hz, very low bass tones, through 20kHz (20,000Hz), the very highest treble. Presumably a speaker that could reproduce that range would sound lifelike. Alas, it is no guarantee. The most important determinant of a speaker’s frequency performance is not its width or range, but whether it’s capable of reproducing all the audible frequencies at the same volume at which they were recorded.
What does flat response mean in speaker design?
Flat response means that the speaker reproduces sound accurately. Too bad that the Erehwon Model 10 doesn’t really exist, and neither does Unobtainium. Today’s technologies allow speaker designers to get closer to the “flat” ideal than ever before, but they still fall far short of “perfection.”.
Can a fool design a speaker?
Only a fool would design a speaker based on measurements alone and only a total fool would design a speaker based solely on subjective listening. A speaker that might sound good on a particular recording may in fact be flawed – it may have what is commonly called a “euphonic coloration.”.
Is there a guarantee that a speaker will reproduce all the audible frequencies?
Alas, it is no guarantee. The most important determinant of a speaker’s frequency performance is not its width or range, but whether it’s capable of reproducing all the audible frequencies at the same volume at which they were recorded.
Does a speaker have a treble amplitude?
Yes, it does. As long as you know the amplitude tolerance (+/- 3dB), the frequency response range or width tells you how high or low the speaker goes. A speaker rated as 20Hz – 25kHz +/- 3dB will play lower bass and higher treble sounds than a speaker that measures 40Hz – 20kHz +/- 3dB.
