CB radios have very limited range to begin with, and fixed channel frequency coverage, so all it will take is a powerful jammer to render them useless over any distance greater than shouting. Dumb plan.
That is a frequently asked question that I addressed in 2011 here at Freerepublic.com
Here’s some of the text and the link:
“The project was not- conceived under the assumption that it would become ILLEGAL- for Americans to communicate with one another. I think if they/he shut down the Internet it would be something of a CHARADE. In this situation, the pretense for example might be that there was a cyber-terror incident in which the cyber-terrorists supposedly did something that warranted an Internet shut down in order to investigate or they shut it down in order to protect the infrastructure or to ostensibly protect us...
There would still have to be some internal resistance just as we have now from Congress and our state governments who are suing the feds. So were probably looking at underhanded attempts using the FCC and other bureaucracies, even czars - to violate the constitution and our rights all while still somewhat constrained by congress (one would hope).
In this case The Saboteur and his accomplices in the Senate would have to stay within the confines of their pretense emergency. So the agenda would be to stifle most of the communication under those pretenses. I dont see them coming out and making a LAW- specifically elucidating their leftist agenda of disabling the freedom of Americans like us to gather and protest in the manner we gathered after the last meltdown.
By staying within the confines of their charade and successfully shutting down communications via Internet and phone availability WITHOUT further legislation, the left could conceivably prevent- another organic uprising the type of which led to the tea parties around the nation almost over-night. Even with all of the existing tea parties and other groups, we are so inter-dependent on e-mail, message boards like here at FR and phones (most of which are cellular) even with these groups having been formed, take away that communicative ability and we are all isolated within the chaos and have no idea when to meet, where to meet, what to bring how to help etc.
I dont see them getting the ability to ban CB usage as there is no valid pretense to justify it. So I dont think it is going to be a situation where we have to speak in code and break any valid laws. I cant speak for all states but I believe my state government of Florida will fight valiantly before that happens; but they wouldnt have nearly as much ability to overcome an Internet and cell network shutdown as we are inter connected with other states etc.
I dont see unmitigated tyranny perhaps until the Chi-coms and the Arabs sack us. That being the case, it is good to have a plan for EVERY scenario. The aforementioned is where codes would DEFINITELY come in handy, in which case we wouldnt be violating any US laws because Trojan Horse Hussein would have succeeded in his obvious long term plan for this country and there would no longer be a US Constitution or US government.”

So basically, I don’t see them getting state cooperation to “jam” the signals in all of these areas around the country. In some of your Blue states, God only knows. That’s why I also rec getting OUT of blue states and move to SC, FL, AL, TX... with good state government.
