I'll second that, Ian! I'm lucky to live in quite, rural QTH with no computers around except my own... So the K3's inherent white/pink or whatever colour noise is certainly something that can be put up with, as in ANY other DSP rig. Wonder why this topic suddenly pops up - and seems to be relevant to so many after 2 years... causing such a "noise floor" on the reflector! I listened to FT2Ks, Orions, ... then purchased the K3. I must have had some good reasons. 73
