Patowalker, spot on. One of the main drawbacks of SafetyCom is that it is one frequency that is potentially used at perhaps hundreds of locations in the UK. Agreed that those locations should by definition be low-traffic, but on a good weekend with several farmstrip fly-ins, SafetyCom can be nigh on useless especially when users do not both start and end the call with the location.
And as far as getting rid of A/G frequencies is concerned, Ofcom seem to be aiming for that anyway with their totally unjustified daylight-robbery fees.
