I just wanted to mention I have had several CB radio's over the years, all of them purchased from CB shops that "peak and tune," some were bought used. I noticed in this thread that the term "illegal" has popped up more than once and just wanted to say that most of my CB's were augmented to transmit more than the FCC legal 4 watts of power. I was comfortable using these "illegal" radios because no one actually checks these things anymore. I want to qualify that by saying none were peaked beyond 40 watts or so. Maybe if one were using a linear amp conspicuously mounted that would be another issue. I am in the transportation business and can say I have never heard a professional driver, even one with a ridiculous (read 500 watt linear amp) CB, mention getting in trouble for it. The key here is being responsible with it. Professionally tuned radios (as opposed to stock/out of the box) work far better and when coupled with a quality antenna/coax/bracket mounted in the right place should work great. This is my experience after 13 years owning tractor/trailers and traveling throughout the US and Canada. I think HAM is the way to go for overlanding by all means, but CB's are easy to get started with and less intimidating at the beginning.
