My earliest recollection of KJIN was as a top 40 station. The studios were on Belanger Street. My memory is a little fuzzy, but I think the PD at the time was Joe Spiers (might have the spelling screwed up.) KJIN was Top 40 at least in 1977 because it helped break ELO "Telephone Line" -- I remember the framed record awarded for that was hanging on the wall.
I wanted to work Top 40 but at the time I applied there were no openings, so I took a spot at sister station KCIL, which was country.
I well recall when we made the switch to "Beautiful Music" and installation of the computerized (sort of) automation setup with those lovely Otari reels. The name of the programming service is on the tip of my tongue, but I recall that it was 100% trade. James Boseman (who is back in his home state of Florida these days) was OM and explained the change in a staff meeting. I was then and still am now baffled by that change. KCIL and KJIN control rooms were switched, KJIN went country and not all of the air staff went with it. Those of us who subsequently worked the KJIN side were responsible for also keeping up with the automation. Our "dead air" alarm -- for those times when we let the reels run out -- was usually a phone call from station engineer Hugh Smith.
I hadn't thought about those days in ages. Those really were the good old days.
