  The short answer is, you can't. The Baofeng UV-5R is not a CB radio. It operates in the 70 cm UHF and 2 meter VHF FM radio bands. CB radios in the US operate on the 11 meter HF AM band. In other words, they operate in different areas of the radio spectrum.

Thanks! I'm watching an episode of (the great 70's series) The Rockford Files, and the scene features a close-up on a police radio, w/ a 'squelch' knob, and not being a radio affix islands, I never knew what it did.
I really liked your short, concise video. It answered all I needed!
Again, thank you very much.

I have four Motorola Talkabout radios, MH230R. Three work fine--the shortish range isn't a problem for my uses. But on one of them, the squelch seems not to be working: The radio stays "on" all the time, hissing away; as you say in your video, it's very annoying! Is there anything I can do to stop this? Failing that, is there any place I can buy just a single such radio, since I already have three others and two chargers?
Thanks,
