They're serious about radio on QRZ, eHam etc., a fair amount of those operators on the forums are engineers of one sort or another. They've done this stuff professionally as well as a hobby. You can learn a hell of a lot about RF there, especially antennas, if the mood strikes you. You might have to wade through pissing contests and chest-thumping to get to the good stuff but it's there. But you won't see CB myths or lingo. They don't use or tolerate it.
