From a cassette labelled Midwest Aircheck MW# 122, Dan Shannon is on the old 102.7 WBMX Chicago.
They call this 102-7 the NEW ‘BMX. This is Contemporary Urban, or whatever they were calling the format back then. Mixed in with a lot of crossover Top 40 hits, WBMX had a captive audience in the Dan Shannon show.
I don’t know much more about either Dan Shannon or WBMX Chicago, other than the call letters were changed to WVAZ on 10/19/88. As of this writing the WBMX call letters reside in Boston at 104.1, the former frequency of WBCN. Prior to moving to that frequency in ’09, the call letters were in use at 98.5 having replaced the old WROR on 02/26/1991.
