Cb channels

Some of the other channels are used for local use. Some company drivers, mainly dump trucks, the guys will be on a certain channel if they are running continuos load on the same route.
Ch 9 I mostly hear Mexicans. Dont even know if cops bother monitoring ch 9 anymore. Hell, dont even know why manufactures even bother putting a ch 9 switch on radios still.

 

CB is pretty much dead, as opposed to what it used to be.

Channel 9 is supposed to be the emergency channel, set asisde by the FCC for emergency use. However there's not many anyone that use it for emergencies, now that we have cell phones. The mexicans you hear on 9 is propagation (a.k.a. "skip") from down south, where the FCC's rules do not apply to them.

So much for the great idea of FCC allocating an HF band notorious for out of country propagation, and then telling us we can't talk more than 150 miles.

Other than that, the remaining 38 channels are free to use. There is a gentleman's agreement to allot channels 36-40 to the single sideband crowd, therefore you have channels 1-8, 10-35 to use at your convenience.

Oh yeah....if you ever get some clown trying to tell you that "channel XX is my/our company channel", remind him that no one has their own channel on the CB, it's free for everyone to use.

 

13 and 16 are used by container yards here

 

Mexicans I hear on ch 9 are local.

dawg, you need a cb the has ssb capabilities. It will have a a knob or switch that has usb/cb/lsb.
Side band is upper and lower freq of the regular cb channels.

Incorrect...single sideband IS NOT upper or lower frequencies.

On a typical CB radio, the signal going out consists of 3 parts: the carrier, the upper band and the lower band. The carrier is for a lack of better terms, "wasted power" as the side bands contain all the info.

When you go to sideband, you remove the carrier and one sideband, thus allowing you to focus all the power into one band. The end result is cleaner, more efficient transmission.

Channel 19 is 27.185 MHz. If you go to channel 19 upper side band, you're on 27.185 MHz. If you go to channel 19 lower side band, you're still on 27.185 MHz. If you just go to channel 19 AM (like you do on your Cobra 29/Galaxy 929) you're still on 27.185 MHz. The frequency stays the same. A single sideband CB radio is still 40 channels, even if the box says it's 120.

Breaker 1-9 can I get a big 10-4 on that c'mon?

And if you have local mexicans on 9, are you in south Texas or New Mexico somewhere?

Sideband is "single sideband", or a mode of AM operation. To put it plainly, on a CB radio, single sideband allows you to talk farther, and more efficiently, however the guy you're trying to talk to has to also have single sideband on his radio or it won't work.

 

And you usually have to use your tuning knob to tune them in so they don't sound like one of the chipmunks, which can be annoying to do while driving down the road in traffic.

 

Turbo- I meant to say upper and lower bands when referring to ssb. Made the mistake of typing freq instead. That was miss info on my part.
I'm outside of Philly and they maybe landscapers on ch 9. (not to stereotype lol)

 

The channel 9 switch is basically a "dummy" switch like you see on your truck's dash. It's just a extra switch incase if you want to add a roger beep or something like that to turn it off and on.
