...network? I have a few GP340 UHF Motorola Two-Way radios, which need to be licensed before I can legally use them. I have not yet tried the programming software, but...

Can I set the frequency channels to the PMR channels in the range of: 446.103125 MHz to 446.196875 MHz (UHF)
The power output to: 4W

and legally use the radios without license in the UK?

or not even lower the power? Please advise.
