I'm getting my K3's set up for the CQWW DX RTTY, and notice that there is a significant variation in power output whenever the FSK goes from mark to space or space to mark. One of these K3's is driving a high gain tetrode amp, and the amp's screen current is jumping all over the place. The power transient is only at the time of transition. The steady-state power of the mark and space are equal.
I've complained about this before, but it seems to be even worse now. I'm using FW rev 3.30. This amplitude modulation has got to be producing some illegal sidebands.
