The Baofeng UV-5R and other Baofeng models are popular for their dual-band capabilities and programmability, but many people wonder if they can be used as CB (Citizen’s Band) radios.
While both devices serve similar communication purposes, they are designed for different frequency ranges and follow different regulations. In this article, we’ll discuss how you can attempt to use a Baofeng radio for CB communication, the limitations involved, and the legal considerations you should be aware of.
Can a Baofeng Radio Be Used as a CB Radio?
The short answer is no — at least not without significant modifications. The Baofeng UV-5R is designed to operate on VHF (136-174 MHz) and UHF (400-520 MHz) frequencies, while CB radios operate in the 27 MHz range on 11-meter band AM channels. This means the UV-5R is not natively compatible with CB radio frequencies.
However, there are a few workarounds to achieve CB-like communication, though these approaches come with limitations and legal risks.
Why Baofeng Can’t Transmit on CB Channels
CB radios in most countries, including the United States, operate on 27 MHz AM frequencies (channels 1-40). The Baofeng UV-5R does not support this frequency band natively because it is optimized for VHF and UHF transmission.
Even with custom programming or modifications, the hardware of the Baofeng UV-5R is not designed to support 27 MHz frequencies.
Workaround Options: Baofeng for CB-Like Communication
If you are trying to use a Baofeng radio for short-range communication similar to a CB radio, there are a couple of workarounds that may work. These options may not replicate CB radio functionality exactly but can serve similar purposes.
1. Use the Baofeng on Shared UHF Frequencies (FRS/GMRS)
One practical workaround is to program GMRS or FRS channels into your Baofeng radio. Although GMRS/FRS is not the same as CB radio, both are used for short-range, unlicensed communication.
FRS (Family Radio Service) channels are free to use but limited to low power (2 watts max). GMRS (General Mobile Radio Service) channels require a license in the U.S. but allow higher power levels.
You can program these frequencies into the Baofeng UV-5R using CHIRP software. However, Baofeng radios are not FCC-certified for FRS or GMRS use, which can technically make their use illegal in some countries.
How to Program GMRS/FRS Channels on Baofeng:
- Use CHIRP software to download your current Baofeng settings.
- Add the desired GMRS/FRS frequencies (e.g., 462.550 MHz for Channel 1).
- Upload the new settings to the radio.
- Use the programmed channels to communicate with FRS or GMRS radios in your area.
Limitation: This method won’t allow you to talk to CB radios, as GMRS/FRS operates in the UHF band, not the 27 MHz CB band.

2. Use Baofeng with a Mobile Repeater
Another option is to use a CB radio repeater that can convert signals between UHF and 27 MHz bands. In this setup, the Baofeng UV-5R would transmit on a UHF frequency, and the repeater would receive the UHF signal and rebroadcast it on a CB frequency (27 MHz).
While this method can allow communication between Baofeng users and CB radio users, it requires specialized equipment and might be technically complex for most users.
Programming the Baofeng for CB-Like Use (on Legal Frequencies)
Even though the UV-5R can’t operate directly on CB frequencies, you can still program the radio for local communication using amateur (ham) bands or shared FRS/GMRS channels. Here’s a quick overview of programming your Baofeng for legal use:
- Install CHIRP Software: Download the free CHIRP software and install it on your computer.
- Connect the Baofeng to Your PC: Use a programming cable (USB-to-Kenwood K2) to connect your radio.
- Download Current Settings: Open CHIRP, select Radio > Download From Radio, and choose your COM port.
- Add GMRS/FRS Channels: Under the Memories tab, add shared frequencies (e.g., 462.550 MHz). Assign each frequency to a different channel.
- Upload New Settings: Click Radio > Upload to Radio and test the new channels.
This setup will allow communication with other UHF radios within a short range, similar to how CB radios are used for local communication.
Legal Considerations
Using the Baofeng UV-5R as a substitute for CB radio can pose legal challenges. Here are some important points to keep in mind:
- FCC Certification: Baofeng radios are not certified for use on GMRS, FRS, or CB bands, which may result in fines or confiscation if used improperly.
- Amateur Radio License: If you intend to use your Baofeng radio on Ham radio bands, you’ll need at least a Technician Class License from the FCC (or equivalent in other countries).
- GMRS License: While FRS channels are free to use, GMRS channels require a license. Ensure you comply with local regulations if using these frequencies.
- Avoid Public Safety Frequencies: It is illegal to transmit on police, fire, or other public safety channels without authorization.
Summary: Can a Baofeng Replace a CB Radio?
While the Baofeng UV-5R and other models cannot directly replace a CB radio due to frequency limitations, they can still serve as an alternative for local communication using GMRS, FRS, or ham bands. However, keep in mind that using a Baofeng on these frequencies without certification may not be legal.
For users seeking true CB functionality, investing in a dedicated CB radio is the best option. If you want to communicate over UHF frequencies with other Baofeng users or nearby FRS/GMRS radios, you can program shared channels as a workaround. Always check your local regulations to ensure you’re using the radio legally and responsibly.
