Glad to see quite a few members influenced by Chicago radio stations. In the early and mid 70s, a time brokered station in Chicago, WXFM, had a show on Monday through Friday, 8 PM to midnight, called Triad Radio. The music was way beyond the rock and pop of the early 70s. I got my first taste of The Mahavishnu Orchestra, Frank Zappa, Can, Kraftwerk, Babe Ruth, IF, Aphrodites Child, PFM, Heartsfield, Faust, Magma and so much more. Each month a "schedule" was published showing some of what would be played each day. The schedule was called the Triad Radio Guide and it was available at sponsors of Triad Radio. I still have a few copies of the Triad Guide and they are pushing almost 50 years old. It's fun to look at them every now and then. My musical appreciation and tastes were certainly shaped by Triad.
Someone asked about Terri Hemmert from WXRT in Chicago. She retired after 40+ years at the station. "Aunt Terri" does fill in work once in a while. WXRT had one of the most loyal followings in radio and the jocks built 25+ year careers at WXRT. It is still a great rock station.
