Thanks for all the replies. This is a great thread as well. Gripping reading.
Just for a bit of extra info I was 2500 feet above the cloud and one of the scottish services passed me to another who most definately gave me RAS (he stated that the service was chaning to that) and then I got changed to yet another scottish frequency.
Normally when I go to Glasgow I speak to just one frequency. 119.87 I think but yesterday there were three different ones. Sorry I cant remember them all.
