This morning I heard Chinese instrumental music at this freq. during
these times. Only music, no voice transmissions. Is this Central
People's BS in Beijing transmitting to Taiwan on an alternative freq.
from their usual 15.880Mhz? It was quite loud throughout the 2 hours
that I logged it. Very tinny instrument in the mix, probably a
Chinese So-Na (trumpet.)

Likely its a jammer (also known as the firedrake) from mainland China
covering the 100 watt station from Taiwan which is scheduled on this
frequency.
