It's been a couple of weeks since I last copied Radio Munansi on 15240 on a Saturday or Sunday, as it's scheduled. But tuning the bands this morning I found that WWRB, the station that relays Radio Munansi, playing African music. I don't have enough of an ear to distinguish between the different styles, meaning I couldn't tell you the difference between Ugandan music or Guinean. But the style very strongly makes me think of what they play on Munansi, and the signal has that same appearance on the waterfall as it did on 15240.

2041 UPDATE - it finally occurred to me to look for a livestream which I found. 9370 is definitely Radio Munansi.
