The engineers here will know if WROW loosening their pattern southwest would need another stick.
It doesn't look like they can send any more power east at Boston, and I believe a fourth stick is
the only way to push more watts out of a pattern that's symmetric -- the way a lot of three-tower
directionals are. I think it's called the axis of symmetry, where ideally an actual line can be drawn
down the middle of the pattern, leaving the same inkblot/information/directional characteristics on both
sides of the line.
Besides, there aren't too many people living in what would be the expanded area.
It's nice to see a station at a heralded frequency like 590 doing well, though.
No doubt it's way too late for WARM 590, however, given the reported equipment
conditions and the apathy toward music on the AM dial. Since this thread began, a
year and a half ago, some folks here probably have been able to grow full beards plus watch
them go grey.
I think that a similar agenda to bring back the music magic of WFIL, or WMCA, or WPDQ
Jacksonville would meet the same obstacles.
