I have both the Navigator and Microkeyer II with built in sound cards and yes I can see a difference (used on other rigs here). Not much compared to my high end sound card I am using in another computer with the K3. It is not one of those professional jobs, just a gaming one from Creative that cost a few hundred when new. Even that is much better against overload compared to the stock internal sound card.
However the new internals are sure better than there were a few years ago! The thing I like using the USB external boxes is normally less wires compared to something like a Rig Blaster Pro. However except for FSK keying the K3 is right up there with very few wires, line in, line out, and RS232 cable. Simple and nice! For years I heard from RTTY contesters to just use the stock internal board sound card. However I do see enough performance advantage to keep using the external boxes or after market sound cards. If you haven't ran calibration on your internal sound card that will also help in performance. I have also found very few internal laptop sound cards that are up to much of the task asked of them, most of the time they are very poor. The two interfaces I mentioned above are worth their weight in gold if I am using my laptop and while bypassing their internal card that most of the time stinks in performance! There are some high in XLS Dels I have seen that don't fall in this category. Like with everything there is always the exception to the rule! 73 de w5jay/jay.. >> I'm using a Thinkpad laptop with my K3.
