Ideally the scope should have a MHz rating higher then the 27 MHz signal you are looking at. Typically that would mean having to buy a more expensive 40 MHz scope. The reality is ones rated as low as 20 MHz are perfectly useful for monitoring the envelope of a CB signal.

I think even a 20 MHz scope is a good investment for anyone interested in learning how to adjust a station for optimum operating conditions. Especially useful in setting carrier levels and modulation levels. Also great for anyone interested in learning more about how electronics works. For hobby use you need not spend more then $75 to $100 on a used scope.
