WLLH site, would also, for similar reasons, would not work either. It's 0.25 cannot touch MSX's 0.5.
WRONG! That was the old rule. Must have been changed AT LEAST a decade ago. Current second-adjacent rule is no overlap of 5 mV/m contours. That's how come we have WCRN and WEEI 20 kHz apart and both running 50 kW-U DA-2. Yeah WEEI protects to the west day and night but WCRN pushes to the east at night and to the northeast by day. The two sites are only 34 miles apart. And more to the point, that's how we are about to have 1570 in Beverly (don't remember this week's call letters) and WNTN 20-kHz apart and less than 25 miles apart, with lots of salt water in the path. One will run 50 kW-D ND-D and the other runs 10 kW-D ND-D.
I think the deal breaker on moving WMSX to the WNTN site is much more likely to be WPOP. But I believe that Rumford Ave is further from Hartford than Brockton is. So the question is how much power 1410 could have without overlapping its 25 microvolt/meter contour with WPOP's 0.5. If, as Peter George speculated, WMSX is running 250W ND-D under STA from its old site, WMSX could most likely get 250W equivalent from Rumford Ave. If so, what community, if any, would fall within WMSX's 5 mV/m contour. Would WMSX have to become Watertown's third AM (after WRCA and WAZN)?
