You have changed your position on this point. Earlier you were arguing the restriction has naught to do with the CAA and was an OFCOM regulation.
re-read my question. [PARAPHRASE]If that is true (i.e. the restriction is imposed by OFCOM) why do the CAA choose to communicate this restriction as only applying to licensed aerodromes and only one type of carrier key usage? [PARAPHRASE/]
If it is a CAA restriction rather than OFCOM (which I believe it is) then stop muddying the thread with irrelevant comments about frequency usage.
If one wants to make a case for change a good starting point is to understand who made the rule and why. To this end I believe it is the CAA’s rule, not OFCOMS and is 'safety' based)
