I checked out 1390 this morning at around 4:30am CDT. I heard gospel on WGRB, the Chicago 1390. I also heard another signal (among several) with what sounded like it could have been either southern gospel or country. So I guess my question is what type of gospel music does WMER play. Their website/stream is effectively down and says the site is "under construction". It's easy to pick out WGRB, because it serves the Chicago African-American community.
So, if the music I was hearing (with WGRB and other signals mixing) was southern gospel, I may have heard WMER, If they play another version of gospel, what I was probably hearing something else.
