This is kinda an old but but i see you never got a reply so if you still want this info here it goes. This info is also just the best way i under stand it and can explain it.
When you transmit on any of your regular 40 channels you are actually transmiting 3 carriers (radio signals) 1 is the regular carrier and then one is your upper side band and one is our lower side band. When you switch to your single side band you would only be operating on the one carrier so as a result you concentrate all your power on to 1 carrier so you can talk farther and clearer... But side bands are a pain in the neck if you plan on haveing a conversation with more then one person, Because the frequency's are a little different with every radio so you have to adjust the clarifier knob to tune in to the exact same frequency as the other person... But you get 80 extra chnnels by haveing this and you can talk farther. Personnaly i use them all the time for getting the extra distance. Sometimes when you are a regular channel you can hear someone talking but they sound really muffeled and you can find them on another channel the are most likely on side bands. Oh and i forgot to mention that in order to use this how ever you want to talk to on side bands must also have side bands.. Hope i did not leave out any info. Hope this helps if you have not learned it by now..
Federal law only allows regular CB communications at 4 watts. Sideband allows you to have a little more power behind it without breaking any laws... It helps when you're trying to travel over greater distances...
