Change Regulatory-domain for US device

Hi All! I have the device for US. And I cannot change frequency mode for another country. Is it possible someway to change ?

No.

This is a feature of us versions. Try to buy international version if you want to break your local rules.

Does the US versions support frequency-mode=superchannel ?

If so you can use that instead and manually change the txpower values

No, there is only regultory-domain.
Thank you all !
