1430 is almost always listenable after dark on Concord Ave just east of Belmont Center. But take a right under the stone railroad bridge onto Leonard St, go through the Center, and proceed across Pleasant St and up Belmont Hill, and 1430 is usually toast within a couple of tenths of a mile. I think what we're dealing with here is more local anomalies in soil conductivity than the eccentricities of a very simple two-tower directional pattern.
During the day, 1430 should come in just fine in Winchester. And if it doesn't, 1200 should be OK, though not as strong as 1430 during the day in Winchester.
It's also possible that work is starting on connecting WILD up to one of WXKS (AM)'s towers, which could mean that 1430 is operating, at least some of the time, at less than full power.
