What on earth would cause you to make a statement like that? A large number of rigs still on the market have fundamental and inexcusably bad key clicks and phase noise that pollute the bands, not to mention the ones with wide front ends that pound the bejeezus out of the AGC from 10 KHz

Re: [Elecraft] K3 DSP processor speed

While I appreciate the input from Wayne on the K3's programming architecture (as well as the facts on the power consumption characteristics), the reality is that many of us have identified other rigs that have implemented NR in a way that produces results that are much more satisfactory. Comments
