Too many to answer here all the American CB channels plus some what they call ( " Free Band Channels " ) the only way I could tell you all the exact frequency`s here would be to go into the radio with the programming software and read the programming data. if I get time I may post a PDF of both bands and frequency's to link to if You own a radio like this and it is not modified and is set in ten meter mode and you want just the American CB Band and channels their is no mod needed switch band switch to high and band mode switch to band E that's it you have all the American CB channels upper lower side bands FM without modification. plus all the 10 meter ham band. Raddioditty has a list of the 10 meter ham channels on their web site but not the CB mod channels. I hoped this helped some and maybe someone in the comments can help you more if I ever read the radio out in programming mode I will try and print them for PDF.
