I'm receiving 15580 khz at 1905 UTC. I checked primetimeshortwave.com and hfradio.org, and they both list this as a Voice of America frequency during that time. But what I'm hearing sounds more like a hip-hop radio station that one might find on FM. A guy is interviewing a singer and playing her songs. I'd say the SIO code is 544, and I'm based in northern California. I'll keep listening for a station id. Anyone know what this broadcast is?
