540 WLIE, 740 WNYH, and WLIM 1580

I was curious about the signals of 540 WLIE, 740 WNYH, and 1580 WLIM. During the day do the signals have a lot of overlap in coverage on the Island? I live in Central Connecticut and WLIE and WNYH are pretty strong particularly on my car radio. WLIE usually comes in stronger. Sometimes I can get WLIM, but it's generally the weaker of the three.

When 540 was WLUX playing Standards, I listened to them every day (only daytime), here in Center City Philadelphia, they were like a local. In fact I won a coffee mug (the music of your life) printed on it, for being the farthest listener. I never tried them since they flipped....so I just tried them now and they are still strong as they were back in the 90's when they were Standards.
