You've got the protection story kinda backwards. WXKW got protection
from WHDH at night because WHDH had to protect KOA. As I reported in
one of my earlier posts, WXKW was DA-1. It protected the much older
WHDH day and night. WXKW's six-tower pattern was an inverted figure
eight on a north-south axis. The major lobe was, of course, to the
north--toward Albany and Troy. Schenectady was in the main lobe but
somewhat off to the west side. As a result, the signal in Schenectady
was only so-so. Besides protecting WHDH, the broad, deep null to the
east protected first-adjacent WNAW North Adams, a 250W daytimer on 860
(now WSBS Great Barrington). WXKW's lobe to the south was quite
substantial. Though not as strong as the lobe to the north, thanks to
the good soil conductivity in the Hudson Valley, it was quite strong
enough to make for a good signal as far south as Kingston--at least
during the daytime. I remember listening to a strong signal from WXKW
on a vacation at Huletts Landing on Lake George--probably in 1950.
