The built-in sound card in the K3S works just fine for RTTY decode - MMTTY and 2Tone - but RTTY doesn't require high performance from a sound card. For more demanding modes I can't comment, but I would definitely expect the K3s to meet or exceed the specs of the Rigblaster, which is nothing special. Ken, I would look into your setup in detail. If you can contrive to do a real time side by side test where you can observe both decodes at the same time that would give you confidence that there is really something wrong, or not.
