I once heard the Chinese Firedrake on 10005khz with such wide audio it was beating the snot out of WWV and WWVH on 10000khz.
Audio links are below!
It abruptly signed off in mid note of their "music" and I've never heard it there since!
There was likely no reason for it to be there, as there's nothing there for them to jam. Something somewhere drifted a bit and it was likely shut off when they noticed it;)
Here's the Firedrake on 10005khz:
