Are you using DATA A or trying to force FSK-442 through the K3 in USB with the TX_EQ enabled? Again, I see *NO* frequency effects (crest factor < 0.1 dB at 30, 60 and 100 W) with my K3 when using DATA A and the LINE In.
Also make sure your sound card does not have any "enhancements" enabled. 73, ... Joe, W4TV On 2015-05-28 9:53 PM, Ken_ke2n via Elecraft wrote:

I have shown, in two attached images, the tones being produced by WSJT FSK441 and then the monitor output of the K3. You can see a substantial drop off of the low frequency tones and some kind of additional modulation of the overall envelope (most noticeable with the higher frequency tone, but I think it affects all). Not sure if this is ALC action or something else. Anyway, the K3 makes a bit of a mess out of some otherwise nice-looking tones.
