UK channels for CHIRP
PMR446, the UK 27/81 CB channels and the IARU Region 1 calling frequencies (145.500 and 433.500 MHz FM) are in the table below. Marine VHF and others are in “Add ready-made channels”.
What transmits
The amateur calling channels transmit (for licensed amateurs); PMR446 and CB are receive-only, because they are licence-free only on their own type-approved radios.
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.
