input: [THE "CHEAT"] Out Of Band Operation [SMART WAY] This is one area you are playing with fire, especially in today's RF spectrum battles. Aside from Ham bands nearby, there are frequencies in use by remote broadcast pickups, commercial licensees, and even the military. If you keep careful track of these (they change occasionally) and know exactly what you are doing, you can probably take advantage of this, but otherwise, you're asking for it. [STUPID WAY] 
output: Make sure you pick the perfect frequency to spend hours jawing with a buddy away from the noisy legal channels; you know, somewhere in the middle of a popular Ham band, or on the remote pickup frequency for a local radio or Tv station! Most of the CB'ers who get busted with this one were clueless (or were too lazy to check) that legitimate users often have reserved frequencies just a little outside the CB band.
