Pilots in the London TMA on first contact with radar calling "London ABC123"; sometimes you don't even get the 'London' bit. Give us all the info!! (All airlines are guilty of this, LOCOs are no worse than flag carriers in my opinion, and it seems to be getting worse recently in the London TMA)
But when you've waited 3 minutes to get a gap, are 4,000ft high, have made 5 attempts to establish contact but been stepped on every time, tried Identing to get attention and not succeeded THEN sometimes I'll just wedge in a "London XXX123 with you" type call. I don't know what else to do.
You guys are just too busy and working too hard with too few frequencies at times.
Cheers
