4600turbo, Let me jump in here if I may.
So far there has been no mention of what type of radio .amp, antenna ect...
If in fact we are talking about a CB thats been modified as they say, and Or a Sweep
Tube amp then you are S.O.L. in my opinion..
Let me give you an example of what I mean. When I got back into radio ! CB at the
time I bought a Galaxie Melaka Base and converted it to dual finals, volted them, and
of course removed the mod limiter. The numbers you would not believe, and then I
put a 6 hole Sweep Tube amp behind it, and gave a new meaning to flat topping a
O Scope 
I could talk on 10 channels at once and my I-Max 2000 was lit up in the
dark. That may be stretching it a bit but not much.
I could talk on neighbors radios that were unpluged and in the closets... he he
All the filters in the world will not help unless We are runnig a clean station and thats
a fact my friend.
If in fact, You are running a clean station then We will have to take it one step at a
time and work thru everthing until we find the culpert, and Yes it can be done.
Let us know and we can help.
