Why do they need to? If the Law says they can charge you then they can, in much the same way that Government has decided to tax us in so many other ways.However it still doesn't answer my basic question which is how ofcom can claim "clear title" to those bands.
And the standard from the other end is better? CAA recognised that there was a problem and have removed the automatic right for FRTOL holders to an AGCS Certificate. If you wanted to legally operate AGCS today you'd have to pass the test and get the certificate.Given the standard of some a/g radio this might be a good thing.
However there are many people out there operating AGCS on the basis of a certificate they got prior to the change, and without ever having taken the AGCS test.
