Wouldn't that have corresponded to the FCC's reduction in "clear-channel"
strategies, and more local market driven commercial agendas?  When I was a
kid in the early 50's I got a QSL card from WOAI and WHO for sending them a
postcard telling them I was hearing them in Columbus, Ohio.  And the whole
point of the 1937 Brown, Lewis and Epstein study was that you DIDN"T need
tall towers for daytime coverage.
