the chances of a CB radio interfering with a tower are near zero, it would be 4th harmonic or more.I remember years back, one of our TT drivers getting himself in trouble with the FCC. He used to run down to Jersey and on his lunch break would sit somewhere across the river from NY and talk on his CB radio. I think it was because he used to run one of those linear amplifiers, that he was disrupting the communications at the JFK control tower. When they found him, (didnt take long), they made him an offer. Gives us the radio and amplifier, or we can give you a $ 50,000.00 fine. They were not happy. He did the smart thing and gave up the equipment. I remember seeing his tractor when he was in the yard getting ready to go on the road. When he keyed the mike to talk you could actually see sparks jumping off the tip of the antenna. Guy was crazy, and the AMP i believe was in the 1000 to 1500 Watt range......
When the multi-theater complex opened up in Randolph (almost on the Stoughton line), they proudly stated that they jammed all radio transmissions in the building. Back then I wore a pager (this was in the 1990s) and it didn't work in their building. It also meant that if someone tried to reach a doctor in the theater for an emergency, they couldn't. Eventually the jamming apparatus was removed or disabled some years later.you can get them online, but they are illegal in the USA
In other countries establishments install them ( movie theaters, etc) to keep people from being aholes.

I don't think it has yet, but I'm sure it will if the radios are made available cheap enough and people realize the better audio quality and lack of noise that is the usual on AM and SSB.Has FM caught on yet in the CB world? I know they approved/added it, but the only people I know who have CBs never use them because everyone else is too annoying. My only experience was with a handheld from Radio Shack back in high school. It was useless.
It is risky posting something like this in here, as I admittedly know next to nothing past the basics, but it would seem if you are throwing enough wattage at it, and it is a hack-job, this may not be so far fetched? I doubt the average dumbass is putting out a very clean signal.the chances of a CB radio interfering with a tower are near zero, it would be 4th harmonic or more.

Not really challenging your statement mind you. I guess I'm more asking "what am I missing".

So far I think there's only a couple of CB (not 10m) radios available and they're running close to $200. When some production competition starts and prices drop to the $100 range, I think there will be a lot of people making the switch to FM.

OTOH, attenuation is legal.When the multi-theater complex opened up in Randolph (almost on the Stoughton line), they proudly stated that they jammed all radio transmissions in the building.
