Whats the difference?

[LordDragr]

What is the difference and/or purpose of all the different radio bands? ex.. lsb, ssb, am...etc

[Mr RadioActive]

If I hadn't worked 16 hours today, Id get more specific. What you listed isnt bands they are modes. Modes are different ways of modulating a signal. Some are more efficient then others. If that makes any sense. The mode has nothing to do with frequency. You can have a multimode radio, with one frequency.

[LordDragr]

wow i knew id get a response from RA but not so soon dont worry if you can you can always hit this back again later on. So what mode does a plain regular CB transmit?

[Falkon MX-5]

A regular CB transmits on the 11 meter band, AM mode.
11 meters is channels 1-40

A 2 meter radio transmits on the 2 meter band FM

AM = Amplitude Modulated
FM = Frequency Modulated

You can also have SSB, which is a bit harder to explain. You can do SSB on the same frequencies as CB, but it's just a different mode. I'm not 100% on it myself. I know it's the signals above and below an RF carrier for USB and LSB.

A regular CB transmits on the 11 meter band, AM mode.
11 meters is channels 1-40

Not exactly. 11 meter band is 26.0000-27.9950 MHz (roughly) it just so happens that the 1-40 are in that band. And AM, FM, and SSB is indeed nothing more than a "Mode." So what RA shared is in a nutshell a good general way to understand it.

And BTW, SSB transmits strickly modulation. The modulation does not ride on the carrier like AM.

just my $.02

[Falkon MX-5]

all I said was that channels 1-40 fall into 11 meters. If you want to be really specific, channel 19 is 11.0354975 meters, but you're not gonna hear me call it that.

GOOD job 231! :Peace!:

[HI-TECH]

theres a reasion thay call it 11m, translated thats 33feet..witch is rufly the size of a full wave antenna for that freqency.. lower the freqency the lager the antenna, hince whit lower goes higher and higher goes lower
