Are we talking early pre-British invasion top 40 hits or are we talking 'Middle of the Road', aka Andy Williams, Frank Sinatra, Nat King Cole, etc?
The station originally had an oldies format, moving to mostly Big band before being sold and adopting a Nostalgia format. At that time the station had a bad reputation, not due to the new owners but rather something from the past nobody could explain to me. The issue they always had was much of greater Boerne at the time worked in San Antonio, so the number of listeners to this daytime only 250 watter (at the time) was slim. As I recall, $5,000 a month was a good month back in 1993 when I was in Kerrville. I think TV News anchor Alan Hemberger (San Antonio, then Houston at one point) owned the station early on.
