According to a NTSB report* on the TWA 800 accident,
NY TRACON has 5 radars located at JFK airport, Newark,
NJ airport (EWR), Islip, NY airport (ISP), White Plains, NY
airport (HPN), and Stewart Field airport in Newburg, NY (SWF).

JFK, EWR, ISP are in Class B or C airspace. Stewart (Class D
airspace) has the R in a circle.
White Plains does not have the R in a circle symbol.

Is there any particular reason why White Plains does not have
this symbol if it has radar?


None that I'm aware of. Perhaps it's because the HPN ASR isn't located on
the field proper. It's very close, it's just a bit south of the general
aviation parking area that's west of hangar E, between Tower and Wolfe
Lanes. But that doesn't seem like a significant distance, and the ASR at
SWF is sited similarly but does have the R.
