I have a faint signal (SIO 252) on 6000 khz starting at 1550 UTC. I heard foreign language pop music. I'm not positive, but my guess for the language is some dialect of Chinese.

According to EiBi, this could be Radio Guaiba or City Sounds. It went silent at 1600 UTC, which makes me think it's City Sounds, or something unlisted like SoH. If there was identification at the end of the broadcast, I didn't understand it.
