How much practical experience do you have with radar of any type?
Isn't it interesting that when I provide a site with basic information you don't question the information. You insinuate that I am some sort of idiot. FTR, I have probably been in the "NY Center" at Islip more often than you have, which is to say at least once. (And not for coffee either.) This doesn't make me a radar expert. But my science degrees and closed curves only SAT score do give me a grounding in logic, which sort of helps here.
