I haven't listened in years. Like Skruf, it used to be on my AM Dx'ing list, along with KAAY, WCCO, WWL, WLS and others. Not recently enough to be familiar with the man that murdered WGN Radio.
EDIT: Just researched the name a bit, and found the connection with Clear Channel Communications, an organization which has heavily contributed to the fatal blow to USA radio. I was a radio announcer for 17 years, ending in 1992. The curtains were coming down, and I ducked out.
