squawk IDENT?
square leg, nice way to get your anxiety level down a few notches when failing to make first contact in terminal area, but then again, i imagine a couple of us doing so, i'm not sure the atco would appreciate his scope burgeonning with a/c symbols going two or three times larger...
i've been taught to avoid doing so, unless requested by atc, due to the corresponding plot/symbol getting much bigger and overlapping others for a significant lenth of time, thus making things worse in a crowded atco scope.
happy landings
