Heard with excellent signals in New York on my Tecsun PL-660 with just the telescopic antenna.
It is usually heard with great signals from 18:00 UTC until 22:00 UTC with programs about African News at 18:00 UTC the standard English Service from 19:00 to 19:30 UTC, a Learning English broadcast from 19:30 UTC until 20:00 UTC, African music from 20:00 to 21:00 UTC and Western music from 21:00 UTC until 22:00 UTC.
While the broadcast is targeting Africa, I imagine you'd be able to hear it in eastern North America and maybe even in the central portions of the continent too.
