China's preferred method of jamming is to run CNR1 at massive power (I'm assuming, anyway, because usually the jamming transmissions are much stronger at my QTH than their nonjamming broadcasts). The Firedrake is actually pretty scarce, comparatively. Usually they use that when jamming Radio Free Asia. But SOH is always jammed by CNR1, and they like to use it against RTI and VOA as well.
