WLW was NOT directional then, and is not directional now.   They had 
then, and still have now, a primary tower that is 189.3 electrical 
degrees, and a standby tower that is 87.8 electrical degrees.

A frequency search for 700 kHz shows some high power night time licenses 
in AB and NB.  I don't remember if those licenses existed before the 
downgrade the Clear Channel concept, which I think happened sometime in 
the 70s or early 80s.

You may be confusing WLW with WCKY on 1530 kHz, which was then and is 
now, ND daytime, DA at night.  I remember it as four towers in line. 
Their primary protection is KFBK in Sacramento.
