Squawk 0013, Mode C or S and listen to Essex Radar, stay around 1300-1400ft, and admire the view. No need to actually talk to anyone until Cambridge.
Tractorboy, thanks for the tips. It's a while since I checked the TMZ (not been down that way for quite a while) but was under the impression that if you did not have Mode S you have to talk to Stansted/Essex when in the TMZ below 1,500 ft (this assumes you have Mode C)?
