Is it wise to buy a CB

Firstly I am a big fan of CB but, always a but, not necessarily a fan of CB radios. Why, well generaly speaking when compared to Ham radio equipment a CB radio can be found wanting. I will give you an example. I have a President Grant 2 CB radio which I was using to have an interesting conversation with a fellow prepper on USB. Sudenly my noise floor went from 0 to over 9 making further communication impossible. In the UK we have 80 CB channels to play with and have FM AM USB and LSB. The noise was over the whole 80 channels and over all modes. This persisted until daylight the next day when 0 noise level returned.

This was the clue as I was operating from a commercial caravan site. For the benifit of the residents the site owners have installed outside lights which are triggered to come on depending on light levels.
Right all well and good. The next night I switched on the CB and waited for the lights to come on.

You have guess it, lights on noise level 9 unusable. Then I had a thought, would this affect my Ham equipment. Pulling out my trusty FT - 897 and tuning to the same CB channel and using the same antenna the 897 was quite as the proverbial church mouse.

What does this tell you about shielding in CB equipment. I do have a few other CBs to try but I strongly suspect they will yield similar results.

My conclusion is that a case may be made that it is perhaps better to buy a ham HF set, have it opened up, which I feel all prepper radios should be and use that in preference to a dedicated CB set.

I know there are legal considerations but after all we are Preppers.

Certainly... More a filtering issue than shielding, but the result is the same... I'd say it it wise to own a CB if you have an amateur radio capable of transmitting on CB frequencies... You know what I mean...

Indeed yes I do know what you mean.

I have to mention that in the Uk that the Radio powers that be tend to leve you alone. The big no no would be if your signal was interfering with commercial or emergency frequencies, then expect the big stick and rightly so.

That said I am surprised at the number of Uk YouTube videos whose authors are showing that they clarely do break every rule in the book. Can't say that I would publicly like to take that chance.

Indeed... I personally avoid getting outside of the law, except when it's really stupid and useless... There is a time to say enough... That said, we have enough frequencies available that there is no real need to use others... I do understand CBers extending their band a little... Like you said, as long as they know where not to go. The problem is the use of cheap amps on the wrong assumption that more power will give you more range... Sometimes yes, but usually not much...
