I had this same question but disagree with the manual suggestion in the case of Baeofung. Even they tell you CHIRP is preferred over their stuff right on the website!
As a new HAM operator all the terminology and technology focused language is not easy to absorb but you need to know all that Greek just get a basic radio setup so you can use it and gain experience. I think a good technical writer could really help the CHIRP documentation to be newbie friendly. That's not me :)
Anyways I had stumbled across a page somewhere on the interweb in the last week that described all the settings and I had meant to save it so I could use it as a reference but now I cannot find it. If anyone knows of the resource, please share!
Thank you,
Nick
