Ok, since everyone wants to answer but doesnt know a thing.....
Here we go. 1st, im chairman of a Cb Radio Club that is mainly for new Cb'ers. Your wanting to know what is the common trucker channel. Well since everyone doesnt know...its 19 in the United States & 18 In the United Kingdom. Unless your on a base station or talking to a friend 19 is where you should be. If you are new, then let me give you some hints on how to get started. 1st, dont talk on 19 for a while, just listen in & learn the slang...or codes that the truckers in your area use. It varies mainly from time zone to time zone (to help give an accurate idea), from my experience truck drivers wont talk to you unless you know the terms they use. Its more of a click you must fall into...sound like your one of them. It will help you to also study a bit on all the truck driving code names. Heres a link, but dont get worried when you get there. Although most of these terms are used...none are all used in the same area.
CB SLANG
Print this off, go sit next to your radio, read & listen. Figure out what is mainly used in your area. AND REMEMBER, truck drivers WILL remember your voice if they hear it enough. Just because truckers drive long distances from point A to point B, doesnt mean they dont make several trips through your area. So try not to annoy them, & it will be simple to get in the fun. Its well worth the wait. 2ndly, you should know that once you have the general hang of it, you need a handle/callsign...aka your nickname. Think of something smart & crafty...but dont use something common. For example: (Bubba, Clutch, Bob, Big Bubba, Pop, Wheels, etc) Those are extremely over used & in my opinion annoying. I go by Reaper, ill talk you to death! See what i just did, i threw a short by humorous story behind it....which is a deffinate pleaser. Anything else you need help with look my club page on facebook up. Its called Citizen's Band Central ....also try looking up Radio Communications & Installations up on facebook to.
