New to the 11-meter band? These answers cover the questions operators ask most often, with links to full guides.
Do I need a license to operate CB radio in the United States?
No individual operator license or examination is required for ordinary CB Radio Service use in the United States. The station must still follow FCC Part 95 rules, including equipment certification, authorized channels and power limits.
Can I use an amateur radio on CB?
Do not assume a transceiver is legal for both services. U.S. CB operation generally requires an FCC-certified CB transmitter. Modified amateur equipment does not automatically meet the applicable CB certification requirements.
Why does my CB radio have good SWR but poor range?
A low SWR only tells you about the antenna-system match as measured at the meter. A short antenna, poor mounting position, losses in coax, obstacles and radio noise can all limit contacts even with excellent SWR.
What is skip?
At 27 MHz, ionospheric propagation can occasionally carry signals far beyond ordinary local coverage, especially as solar conditions change. Long-distance reception does not guarantee two-way communications, and band conditions can change quickly.
Which channel should I use?
Try Channel 19 for road and travel conversation in many U.S. locations, Channel 6 for active AM DX listening, and other clear channels for local conversation. Usage conventions vary by community; channels are shared.
Where do I start?
- Read our CB Radio Basics guide.
- Look up any frequency on the 40-channel chart.
- Review antenna selection and SWR before transmitting.
