I use PMR466 however how legal it is I don't know, the radios when they arrived were out of band, and I used chirp to reprogram them to PMR466 frequencies, but there is nothing on the radio to say they are correctly tuned and power at correct level, but who is likely to stop me and check in Mid Wales? And I know they are set correctly now, we use them on the push bikes to say things hang on my chains come off.
