I was wondering if what you are hearing is the result of overload of the DSP. I do most contesting with a Ten Tec Titan. Although it does very good QSK, I've also had the experience of vacuum relay failures during a contest, so when I'm using it, I don't use QSK. I do use QSK in 100W contests like NAQP, and I don't remember the sort of issue you describe. Of course, other signals are 15 dB weaker too. :)
I have the 8-pole 250 Hz filter, and have it engaged most of the time for CW contesting. On the lower HF bands, I usually have the Atten engaged and the preamp off. On the higher bands, Atten is off and Preamp is usually on.
