The problem is that the two official sources of info, NATS and CAA have some lag in their systems. As I have a pint waiting for me in the bar I haven't time to explain in detail, just to say http://www.newfrequency.co.uk has proved invaluable thus far.
Why oh why can't the date of the frequency change can't be synchronised with the AIP/NATS/CAA update cycle.
Not sure if your post may refer to the following:
There is a standard 90 day delay in notification of change to it appearing in the UK AIP, or any other State AIP for that matter. hence the publication of a NOTAM from Date/Time to Permanent. Many 3rd party briefing suppliers, Jepp and others take the NOTAM as an indication to prepare an update.
Sadly many of the Program/Project Managers I worked alongside didn't realise this and anyway the CAA seem to have a policy of not encouraging NOTAM for the frequency updates. There would be a lot so I can see that the system would blossom in content.
If the licensing people are only notifying the new frequencies on renewal of the licence, or application for a new one, then those parameters are often shorter than the 90 days, we had official notification of our new frequency 30 odd days ahead of new allocation.
