Wayne, Thanks for the quick reply. My friend and I were discussing ways of doing this (that is, sending/receiving clear voice with DSP helps) and then I decided that it has been done. Well, not by the K3 because it does not digitize the actual signal being sent but I was thinking of D-Star and its use with repeaters. I wonder how wide that digital signal is, maybe you know. D-Star on HF might be too wide.
