Puerto Lleras xmttr in Columbia, 1 kw
Right about grey line, decent copy for about 5 minutes then abruptly faded out.
YL and OM announcers in Spanish I imagine with music and talk.
Also Radio Melodia 5940 kHz from Peru, Arequipa xmttr, 1kw. 2322z music, good copy.
I love DXing these low power stations from South America.
