I remember both WESA ("The Voice of the Monongahela Valley") and on a couple occasions visited its old studios on the other side of the railroad tracks in Charleroi. It was an admirable AM-FM combo with a good daytime AM signal and a 3-kw FM that covered the mid-Mon Valley nicely at night. Sadly, it now is a memory as are so many of the stations that once served once-vibrant cities of license (WEDO and WMNY-the former WMCK/WIXZ/WPTT- come to mind in McKeesport).
WKZV (as WKEG) had a pretty good news director in Earl Bugaile, who was very effective as local newscaster for one-time CBS affiliate WEDO and now still graces the KQV newsroom. WKEG once had half-hour news blocks, one in morning drive, one at noon and the third in afternoon drive, all of which seemed to work out very well in winter as well as summer.
To quote that duo from the '60s, however, "but that was yesterday, and yesterday's gone."
