in referance to using the singal streath meter on the radio while recieving, are the first 1 thru 9 considered s units or maybe dbs?? courious as to the use of how easy the sending radio can use the first 9 numbers, then it gets tough to make the meter read after you hit 10 over?? ive heard people say you 10 over s9?? in my own thoughts, dose it take, say, another 9 numbers to raise the signal i s unit over the 10 mark?? are the meters on the radios calibrated so that once you get to 10 over its harder to raise the incoming signal so that you could give a person a radio recieve report?? i no this is not making to much sence, but i think some of you have an idea of what im looking for??? ya i no???????? lol.. thanks

THE "S" METER !
The "S" meter was set up as follows ...
Collins radio back in the 40's used this as a standard ...... NO METER COULD FOLLOW IT ....
+ 20 DB over "S" 9 = 10,000 UV
+ 10 DB over "S" 9 = 1000 UV
S-9 = 100 UV
S-8 = 50 UV
S-7 = 25 UV
S-6 = 12.5 UV
S-5 = 6.75 UV
S-5 = 3.38 UV
S-4 = 1.17 UV
S-3 = .56 UV
S-2 = .28 UV
S-1 = .14 UV
So a "S" meter is USELESS ....... |

The voltage for the "S" meter was derived from the AGC loop or in some cases from the diffrence between the cathode of the 1st if and the audio output tube. THE PROBLEM IS it's not linear even remote cutoff pentodes commonly used as IF tubes can go that far signal wise...... |

"So a "S" meter is USELESS" Bruce, I couldn't disagree more. I can't count how many people I have found (for one reason or another  ) by using that wonderful little meter. Also it has kept alot of people from finding me. But I guess it's what you use it for that determines how useful it is. I can always look at an S meter and even though it has little accuracy, it brings back lots of memories.
But that was a long time ago, GOOD TIMES  |

Bruce, I agree 100% that an S meter is not an accurate tool. I wasn’t saying you were wrong and apologize if you took it that way. I was just reminiscing of my younger days... |

Whenever someone ask me to look at my s meter they say "How many pounds?" I usually lie to them cause I feel no 2 radios will read the same, worthless in my opinion. Hey they are fun to look at and the guys who are infatuauted with swing love them! |

if they're hitting S-5 on the meter, tell them "I got you with a solid 5 Lbs" (Lies, and Bull). Remember, you're appealing to the man's ego. If he hits you in the red (Strawberry patch), then you're on your own (Make up some more Lb).

My radio is metric so I measure signals in kilograms!
I wonder how the pound thing got started? Gotta love it! Good ol American cb'ers! 73 |

Actually, I have an idea where pounds started. Amateurs are notoriously frugal, and they make use of used or surplus equipment whenever possible to keep the price of their projects down. That includes meters which are expensive. I would imagine someone used a meter that was marked with PSI or some other unit that was shortened to just pounds when signal reports were given.
That's a good idea Hotwire. I think I'll give future signal reports in Newton-Meters and totally confuse everyone. |

Actually the term "pounds" came from a lack of knowing what "db" symbol on the s-meter stood for, so these unimformed ones associated it with "lb" hence pounds. |

Never heard that before but it makes sence .....
MUCH of CB fokelure is because of hear say ....
EXTRA CHANNELS, EXPORT RADIOS, ANTENNA STORIES and RULES AND REGULATIONS Every one has a life of it's own.
So why not not understanding DB ?
And lets not forget the people tring to SELL Radio stuff ...... Yep a 9.9 DB gain 1/2 wave vertical comes to mind .....

Hey guys. I do not know how I missed this one, but it is funny!! I also used the term #'s back in early 70's because that is what I heard everyone else use. Bruce, don't you know what a "Pound Unit" is??????????????????????????
Don't worry, cause I don't either!!  Sorry sir, I could just not resist!

Much better than just dropping them over the floor ...
