That's interesting. According to the EIBI schedule, RFA is in Tibetan on that frequency, but at 0100-0300 and 2200-2300. Maybe they were sneaky and tried it at a different time to avoid jamming? (Assuming that you heard Tibetan - I think other, non-PRC-targeted broadcasts are not jammed, at least not as effectively as the ones in Tibetan, Mandarin and Cantonese.) Anyway, nice catch with the positive station ID.
