With it's haydays in the 70's long gone by, the public has generally opted for the more modern cell phone to communicate.
At one time almost every other vehicle could be found with a CB.
Now more of a hobby,there are still a number of active enthusiasts.
radio frequency range, worldwide service:
26.965 to 27.405 MHz
still used all across the USA by truckers for the avoidance of police officers cops and in the rest of the world by terrorists and FARC
Channel 9- international emergency channel
Channel 19-international calling/trucker channel
The FCC (US radio regulatory agency) once required licenses for CB. The popularity of CB in the 70s resulted in much illegal operation. The FCC dropped licensing requirements in the early 1980's.
North American CB today is a wasteland of cursing, vulgarity, sexual innuendo, jamming, music broadcasting, and heavily distorted audio due to improper radio modifications. Amateur radio (ham radio) operators have a particular dislike for CBers and CB lingo. CBers sometimes transmit illegally on ham radio frequencies and are often caught by vigilante hams with radio direction finding equipment. Ex-CBers who get ham licenses are often ostracized for using CB lingo on the air. It is a grave insult to call an American ham operator a CBer.
Ham 1: "Did you hear that new ham on the repeater? He was using CB lingo like 'what's your 20?'"
Ham 2: "Yeah, I'll have to pull him aside at the next hamfest and talk to him about it."
