Lately I've been getting a C-Quam AM Stereo pilot tone from 1660 WWRU, although since their programming is all Korean talk, there is little, if any, chance for them to actually broadcast anything in stereo. I believe they are the first NYC-market station to transmit a C-Quam signal since around 2003 or so, when 660 WFAN turned theirs off.
Leonard Kahn still has a holdout, too: 1600 WWRL is transmitting Kahn Power-Side on the upper sideband, with the 15 Hz Kahn/Hazeltine AM Stereo pilot tone.
