I was wanting to know when did KOLA 99.9 switch from top 40 as "Triple 9 FM" to their current oldies format? Although the aircheck that they posted recently was from 1988 when they were a top 40 station, but when I first came through San Bernardino in 1993, KOLA was starting their oldies format. So I would be guessing sometime in the early 90's, I believe. But I don't know when the switch happened. Could you find out for me?Thanks.
