Yes, indeed. In addition to Dale's  comments, I would reinforce the fact 
that a very high percentage of RF noise appears as a common mode signal 
on interconnecting cables, and that the addition of a good common mode 
choke that is resonant near the frequency(ies) of interest is always a 
good first step.
