Dan,
I worked for the 1110 in Providence in the '80's when it was country WHIM. It's now Spanish Tropical WPMZ,and doing well. I don't think there were problems with interference when it was still 1 kW non D. If memory serves, power was upped to 5 kW DA-D in '86,a wide 2 tower cardioid directing the power SE from the transmitter site in E. Providence RI. I'd get get requests for stuff from Jersey before sunset. The 1110 in Norfolk is still around; it's now religious WYMR. I heard it slam into the Outer Banks of NC, in a town called Duck, on vacation there 2 yrs. ago.

I'm amazed that the Norfolk 1110, with its major lobe to the southeast, doesn't step all over WBT's 0.1 mV/m contour in eastern NC. 0.1 isn't a big signal, but for Class A AMs like WBT, it's supposed to be protected from co-channel groundwave (of a mere 5 microvolts/meter), at least during non-critical daylight hours. The 0.1 is not protected from first-adjacent interference during the day or at night, however; first-adjacent protection is limited to the 0.5 mV/m groundwave--and sometimes more. At night, it's surprising how many US Class As are not protected from co-channel interference to the 0.5 mV/m groundwave, let alone the 0.5 mV/m 50% skywave. Of course, these stations are protected from co-channel interference better than virtually all Class Bs, but still, the 0.5 mV/m contours are far from sacrosanct.
