I usually keep my mouth shut on this topic but i will spew just this once.
I have always had a CB since my early teens in the early '70s when callsigns were still issued. You weren't supposed to have casual conversations so bootlegging by deleting your callsign and inserting a handle instead so "charlie" wouldn't hunt you down and slap your hand with a ruler was the game. Skip came and went and it was kinda fun to make a call to someone in the midwest and they answered you back. Hardly anybody had or could afford or retained the smarts to boost there transmit power with a "footwarmer". Most people you talked to were cordial and easy to talk to.
Then a little later came all those crazy movies and songs hyping the truckers and the CB thing. Suddenly every kid (with a car) wanted a CB. The channels increased from 23 to 40 and they almost all full with some kind of chit chat. In the early '80s went to San Diego to visit my cousin. He and I went cruzin' the strand at night. Well seems everybody had a CB in their car and if you wanted to find out who's out, where the party is or who's getting busted, you'll have to check one of several different channels to get the info you need. Fun times.
Today I put CB into two categories. Skip or no skip. With no skip you're limited to local groundwave communications. This limits you to several miles miles and maybe 15 to 20 miles in a good location. More if you can get in a high spot. This gives you mostly individuals of lesser maturity that cuss, play the key down game or constantly invoke their noise toys. This relentless cacophony of noise has driven most sane users from the band. Even truckers seem to turn their rigs off and are silent on the road and then only power up in the yard for directions from the scaler or dispatch. To hear a local station transmitting coherent voice is rare indeed.
When the skip is up and rolling, just forget about having the radio on. Yeah, you could try your hand at one of those far off stations, but after yelling and screaming your head off time after time after time just to maybe get an acknowledgement without any confirmation of the contact gets old after about twice. Skip just raises the noise floor and negates any real use the CB was designed for. I had the CB in the truck a month ago when I was freewheeling the dirt roads of Death Valley thinking that is the most probable form of communications (although I had the 146/440 radio scanning call channels and such and the other radios scanning MURS and FRS and GMRS) I found myself cranking the squelch up and RF gain down so much to git rid of the mindless okie dribble coming in on skip that if a real local call came up on channel for assistance, they would have to be a half mile or closer to be heard. This is bordering on the edge of useless.
Am I being overly critical of CB and what it has become? You bet I am. Unless you want very very local communications or are traveling in a tight caravan where you can crank down the radio to limit you to the parties you want to talk, you are open the most headache inducing noise ever heard through the radio. The CB band is totally useless for the service it was intended for and anyone should think twice about considering it for any serious communications.
