Can any one tell me the difference between CB and 10 or 11 meter. I know that a licence is required for 10 meter, but i have not figured what the major difference is. Is it power output, frequency, or something else. Will any one please explain "meter" to me. Thanks |

Hi JUSTIN,Poweroutput,frequency,talkdistance and operating modes are just a few things that differenciate CB from HAM radio.Hams have more privilages
Hams have the use of 10metres
HF CB falls into to the 11metre band in your country with Ch.1= 26.965Mhz to Ch.40 27.405Mhz.In my country Ch.1 26.330Mhz to Ch.40 26.770Mhz
Meters are things that move or swing on the front panel of test gear or radios.
Metres are a metric measurement in our case it relates to a radio wavelength.
I do hope I have not confused you.

A meter is a unit of metric length equal to about the length of our non metric "Yard".
11 Meteres is CB. 10 Meters is Ham/Amateur.
The difference is the difference between light and day.
CB: Limited to one segment of radio frequency, use of only certain authoried frequencies, power not to excede 12 watts, antenna height restrictions of 60 ft max, and no talking of skip.
Ham/10 Meters: Once you are issued the license of course--one band of frequencies, Power depending on where you transmit maxs out at 1500 watts (in some areas just 100 watts), unless you are near an airport or in an historic area you are limited to a max of 200 feet, skip or DX talking is the norm and is very much encouraged.
These are just a few of the differences and features. And once you get your General Class Lincense you become a Short Wave Radio Operatior and are authorized to talk to the world on a very wide range of frequencies between just above standard commercial AM radio thru 10 meters and well beyond/abive the standard FM Commercial frequencies.

Re Justin....
I was A little to fast on the enter key. One more thing ya need to know in order to make an informed decision.
The Ham or Ameteur License does not authorize you to use your ham radio gear on CB frequencies. The two are two entirely different radio services each having its own set of rules and regs that apply only to it.
Check out the Ham Radio BB on this site if you have any questions about how to become a ham op.

Justin hers the scoop!
Meters M= 300/f so 300/27=11 a meter is used to show how long the radio wave is at cb it takes 11 meters for the radio wave to travel one cycle and a antenna works best if it is cut to part of that wave lengh ..... this is where 1/2 5/8 wave antenna comes from.
11 METERS ( CB ) you have 40 cn 4 watts am/ssb thats it .... yea i know few follow that but this is the law! CB was intended for personal radio needs including small bussness it is a shaired radio you only have 40 channels
10 meters (HAM ) you can use any freuqency from 28.0 to 29.6 ... in cb channels thats 170 channels. However since it is not channelized it realy is much more! You can run CW, AM, SSB, FM, RTTY, SSTV and many more modes. You are allowed more that 200 times the power of cb HAM IS a hobby and can only be used for that you cant use your ham radio for your bussness. For information on HAM radio here is the website ...

Justin,
Meter is the metric measure of distance. When talking radio transmision it refers to the length of the antenna needed to cover or transmit on certain frequencies. The international radio comunity has desiginated certain frequencies to certain levels of operator knowlege.
CB or Citizens Band is used on 11 meter. No licience required. Plug and Play. As one progresses in knowlege and can show this via testing they can use other frequencies as well as add power.
Hope this clears things a little. |

First off cb and 11 meters are one in the same. 10 meters is a slightly higher frequency than cb/11 meter. CB ranges from about 26.965(or close to that, I forget) to 27.405 in 10 kc steps with a few gaps here and there. 10 meter is 28.000 through 29.660. FCC alots these fixed freqs. for the cb band. As you know 10 meter is a licensed band and it's propagation characteristics are much like cb, although it's much quieter than cb due to mainly that less people use it and most are on ssb, and that cuts down on the whining noise among other things (hetrodyne). Meter refers to the wave length of a freqency. A wave length on cb is 11 meters long or about 33 feet, a 1/4 wave for cb is about 102 inches long. Hope this helps some. sb106 |

OK the major differences (apart from needing an Amateur Licence for 10m)is frequency (10m= 28.000MHz to 29.700MHz while 11m = 26.965MHz to 27.405MHz), power CB is limited to 12W PEP amateur radio allowed up to 1KW LEGALLY and finally themodes of operation allowed.ON CB you legally can only use AM or SSB voice while on10m we amateurs can use AM,FM, SSB,CW (morse) and various digital modes.Add to this we have several repeaters in operationon the high endof 10m too. |

11 meters is the CB band. The frequency range is from 26.965 MHz. to 27.405 MHz. Allowable modes are AM, LSB (Lower Side Band) and USB (Upper Side Band). No license required. Equipment must be FCC type accepted. Maximum power is 5 watts input to the final stage (about 4 watts out).
10 meter is the highest HF ham band. The frequency range is 28.000 MHz. to 30.000 MHz. Allowable modes are AM, CW (Morse code), LSB, USB, FM, and many others. License required. Equipment does not require type acceptance, you may even build your own. Maximum power is 1,500 watts. |
