Guys do you not know why there is a difference between the callsigns APPROACH and RADAR? Do you not realise that (usually, Guernsey being a notable exception) an air traffic unit with the callsign APPROACH is working PROCEDURALLY - i.e. no radar? That means we cannot give you radar vectors to the ILS no matter how many times you
ask!!!
I think you'll find a lot of units with the callsign APPROACH providing radar service.
