Licence holders are only entitled to use the radio equipment for which they are authorised whilst in the course of carrying out their duties.

Do you have a reference for this as I don't find these words in the regs.
As far as I am concerned my RT licence gives me authority to use a radio on the airband in the manner described here. Has this ever been found to be otherwise ?
And as a recreational PPL I don't have any "duties" anyway !
