Citizens Band (CB) radio celebrates 60th anniversary

Many thanks to SWLing Post contributor, Ron, who reminds us that today is Class D CB radio’s 60th anniversary. From Wikipedia:

On September 11, 1958 the Class D CB service was created on 27 MHz, and this band became what is popularly known today as “Citizens Band”. There were only 23 channels at the time; the first 22 were taken from the former amateur radio service 11-meter band, and channel 23 was shared with radio-controlled devices. Some hobbyists continue to use the designation “11 meters” to refer to the Citizens Band and adjoining frequencies.

My dad was an avid CBer when I was a kid. He had an FCC-issued license and belonged to a healthy community of CBers in our part of the state. He had a beautiful yellow Robyn T-240D (same as pictured above) as a base station, and a mobile CB installed in every car. After the FCC dropped the licensing requirement, his activity on the bands slowed down although it did give me a chance to hop on.

My best friend (who lived about 1/4 mile away) and I used to keep in constant contact with our 40 channel 5 watt CB walkie talkies. It was great fun.

Of course, it was a treat when I would catch some “skip” and make contact with someone two states away with that same walkie talkie.

Like it or hate it, a lot of radio enthusiasts and ham radio operators cut their teeth on CB radio.

I was certainly one of them.

CB radio is still a pretty dynamic public radio space today.  True, it’s a bit of a free-for-all and if you can’t tolerate profanity and “colorful metaphors” then you best stay away.

You don’t need a CB radio in order to listen to the CB frequencies; most SDRs and many portable shortwave radios can tune in. If interested, check out this previous post: Listening to Citizens’ Band (CB) radio on your shortwave receiver.

“I found this web page  that my be of interest to your blog readers. A guy named Drew Durigan has saved CB radio audio of himself talking to his friends when he was a teenager in the 1970’s. Its mostly kids talking smack about each other with CB radios, kind of like kids do today with text messages and facebook.  The web page is called Radio Geek Heaven.”

Note that Drew has also posted numerous FM/AM air checks on Radio Geek Heaven as well–a lot of good audio to dig through.

Thanks for sharing, Chris!

Listening to Citizens’ Band (CB) radio on your shortwave receiver

React International coordinates emergency response via CB radio.

Did you know that you may be able to listen to CB radio on your shortwave receiver?

If you have a digital receiver that covers from 26.9-27.5 MHz, you can listen to CB frequencies in a matter of minutes. Below, I’ve posted a chart of all 40 CB “channels” and their associated frequencies.

Why listen to CB radio?

  • Find out what road conditions are like from local drivers by monitoring talk between truck drivers
  • Monitor Channel 9 (the emergency channel) and contact local authorities if you hear a distress call
  • During an emergency you could glean valuable information from the CB frequencies
  • Entertainment value: hey, it’s CB–you never know what you may hear.
In fact, note that CB listening isn’t for those who are easily offended by adult language. In the past, CB radioers were licensed by the FCC and tended to be (in my humble opinion) more courteous. Today, it’s a free-for-all, but  you will still hear many regulars that are respectful and follow the “gentleman’s rules” of amateur radio.  Simply tune to the frequency below and listen. Like broadcasters and some ham radio operators, CB is primarily an AM mode activity. Make sure your radio is set for AM (not SSB) listening.
Here is a list of all 40 CB channels and their associated frequencies:
CHANNEL FREQUENCY   CHANNEL FREQUENCY
1 26.965   21 27.215
2 26.975   22 27.225
