i have been looking and looking but only finding freqs for channels 1 to 40 .. and the CB search banks in scanners only scan channel 1 to 40 so what are the CB upper and lower Side band freqs so i can program them to listen to ??
as ttkoestner replied Single Side band if that is what your looking for is the same channels as the normal CB channels...... but many Export radios ... or radios in other countries use 120 channels... 40 above and 40 below our normal CB band Band D ......i have been looking and looking but only finding freqs for channels 1 to 40 .. and the CB search banks in scanners only scan channel 1 to 40 so what are the CB upper and lower Side band freqs so i can program them to listen to ??
CB users tend to use Channel 16 and Channels 36-40 in the United States for single sideband operation.
This is a Gentleman's Agreement and not FCC Rules.
If you're trying to find SSB activity (and you'll need a radio capable of receiving it) -- start with those six channels.


Great bunch of info.... I have never tried 16 20 or 28 LSB I just didn't think anyone used LSB other than 35 to 40.... I have never used my USB or FM on the Quad 5....,. I've tried FM on the President Grant several times in the 90's but never heard a sole38-LSB busiest, followed by 28 & 20.
These are the hobbyists looking for the greatest number of contacts.
Other activity on LSB are those who’ve shifted from one of those hailing channels by a few channels up or down.
There can be a correlation with the AM side where operators are staying in contact; sometimes 1 to 2-channels adjacent (from AM-19, for example).
Think, “clusters” near to popular channels so as to more easily return to start point. (One, two, three channel clicks).
“Let’s go to Low Side and down 3” (16-LSB from AM-19). Citing frequency change number is the other. (From 27.185 to 27.155).
USB pretty quiet by comparison.
When Skip is heavy is when one hears more activity across the board as foreign stations are more easily heard.
See ALPHA CHANNEL note on figure below.

Scanning the CB Freqs is going to be most satisfying with a modern (post-2022 release) radio equipped with a DSP filter (called NRC).
This maximizes Signal Capture in a sense as now the radio can decipher for your ears what before this it could not.
A Scanner just won’t have the RX capability of a dedicated unit.
Freeband is that which is a subject to itself, but which a radio as depicted below is capable.
It’s easy to Scan either via Squelch Break or by Time (x-seconds per channel) and one can do this in any Mode.

“Mode” is really the OP question.

so your saying SSB is more like a PL or DPL code .. a freq inside a freq rather then a lower or higher freqSSB freq's are the same as the regular 40 channels. However you will need a ssb radio or a scanner that does ssb to be able to understand the transmissions.

Its the upper side and the lower side of the orignal AM carrier its not a seperate channel.
You will need a radio that can recieve and transmit on these upper and lower sides of the Carrier.

No PL means Private line - The Radio generates a low frequency hum on the Carrier - The receiver picks up this low frequncy hum and gives you permission to use the frequency ( A Repeater ) as an example. - PL and Digital PL is a Key to Open the system up.so your saying SSB is more like a PL or DPL code .. a freq inside a freq rather then a lower or higher freq
i sent a PM with some info.some info
