Note that on the Amateur frequencies, it's illegal to "Obfuscate" your transmissions. You can't even use coded language.

  Didn't know that. Surely some people tried steganography? Or is there too much noise to try something like that? (and thanks for the antenna book recommendation)

    That would count as "obfuscation".

      It's really hard to prove steganography if you are hiding encrypted data (which looks like noise if it's properly encrypted)
