BU sells WRNI

[Dan.Strassberg]

It makes sense that towers 1 and 2, which are common to the the new
day and night arrays, would be originals but that both of the separate
(northwest) tower 3s, which can't be more than a few feet apart, would
be new. One of the tower 3s is used by day; the other is used by
night. I'm pretty sure that one of the tower 3s is in the same
location as the old tower 3, which was used day and night, and that
towers 1 and 2 are in the same locations as the original towers 1 and
2. Both of these were and are used day and night. However, it may have
been necessary to replace one of these two towers either because it
was in need of repair or because it was necessary to anchor the guy
wires in different locations to make room for the second tower 3. If
there was a conflict with guy anchor points, the affected tower would
have been the center tower, which is tower 1 both day and night. In
that case, the southeast tower (tower 2) would be the one that was
left standing. I believe that it was the new day pattern that required
the relocated tower 3. It's bit surprising that a suitable 10-kW day
pattern could not have been designed with tower 3 in its oroginal
location because the new daytime-only tower 3 is so close to the
nighttime tower 3. However, 1290 in Hartford is not very far away and
probably made the pattern design challenging. The proximity to
Hartford explains why the increase to 10 kW couldn't do much to
improve the daytime signal on the west side of Naragansett Bay.
