Channel usages for the 27MHz band (In Australia).

Channel Usage
8 Road Channel, for travelling & truckies.
9 Emergency channel (AM).
11 AM calling channel.
16 SSB calling channel, LSB is used.

On the 27MHz band channels you can talk generally on all the channels apart from the designated ones. What AM and SSB is will be defined later.

Important points to remember.

SSB is used by those that generally have a genuine interest in communicating with others, to make new friends, and explore radio communications further. AM is also used like this but differently, mostly (but not only) those seeking short range communications to make local friends and just meet anyone while travelling and the like. More of the much younger generation use AM, about 12 years old and upwards, where as more of the adult and seniour community prefer to use SSB. (This is 100% relevant to the area I live in and most capoitol cities in Australia, however may vary overseas.)

On 27MHz CB it's mostly possible to speak locally, and also thousands of kilometres in distance (termed 'skip'). This is possible with the correctly setup and tuned aerial equipment, specified mostly on the next page.
