CB channels for CHIRP
The 40 US CB channels in AM are in the table below — note that channels 23, 24 and 25 are not in frequency order. The European FM plan and the UK 27/81 channels are in “Add ready-made channels”.
Which radios can use it
Only radios that receive 27 MHz: wideband receivers and some handhelds such as the Quansheng UV-K5. A Baofeng UV-5R does not — “Check for my radio” says so for each channel.
Transmitting
Transmitting on CB needs a certified CB set; the file is receive-only unless you untick it.
Before you load it into a radio
The file is for CHIRP, the free programming software — not for the radio itself. CHIRP is what writes the channels to the radio, and CHIRP and the radio decide what they accept; we cannot check that without your radio. Before uploading, download the radio’s current memories in CHIRP and save them as a backup, then look through the channels. Transmitting on some frequencies needs a licence or an approved radio — check the rules where you are. You use the file and program your radio at your own risk.
