There is an Error on one of the posts on this story. I was There when it Happened, when the
switch was made!!
It was Spring 1965, not '67, that KLAC-FM and KRHM traded channels. 9:00 PM on a Friday night.
I had two radios set up to watch and hear. KRHM (which was on FM only) made the transition quickly.
It took them less that a minute to dump carrier on 94.7 and re-appear at 102.7. The audio was great
when they came back. Both carriers had dumped almost simultaneoulsy just moments after 9:00 P.M.
KLAC, at that time was a simulcast, of 570 AM. It took them almost 45 minutes to get the carrier back on
at 94.7 and the audio was rather distorted (overdriven). By midnight the audio simulcast of KLAC-AM
sounded pretty good. It had sounded great on the 102.7 channel that they had just left.
I was in this same basic time frame (Spring 1965) that KMLA 100.3 morphed into 100.3 KFOX-FM.
That again was an audio diaster on the FM as KMLA signed off with good audio and then KFOX took over.
That transition sounded like KFOX just put a table model AM radio tuned to 1280 KFOX up to the mike
at the KMLA studio and let it go that way for several days. Really bad audio for what once had been
LA's Pioneer FM Multiplex Stereo station (the first one in multiplex stereo). That is was what KMLA had 'bragged' (promoted) about for several years.
The wikipedia KIIS page does also contain the 1967 as opossed to 1965 error too. I KNOW I'M
right on this detail, because it was before I moved back east in 1965. The Wikipedia article does
not mention any 102.9 channel. That station (now KIIS-FM) was never at 102.9, always 102.7!
The table of assignments put 102.9 in San Diego from the beginning.
