There's also XEFNDH 1290 at San Mateo Yoloxochitlán, Oaxaca (no idea how those calls got there).
Now I have an idea thanks to some buried transparency filings. This was (almost certainly) to have been an indigenous station to be awarded to the Fraternidad Nacional de Organizaciones de Derechos Humanos.

An FM application from this group for the same locality was thrown out by the IFT, with the given reason being "Application dismissed for failure to respond to a written request".
