Brian, I agree with that. The K3 does sound different than many other receivers, it is cleaner, and to my ears reproduces the signals that are actually present on the band more faithfully than many other receivers. Compare the K3 to a good Direct Conversion receiver or a KK7B Phasing receiver without a lot of audio filtering. Yes, the K3 audio does have more high frequency content than required, so a low pass filter can strip that off for those who are bothered by the high frequency content. That was what the filter on the DSP board is supposed to do. But the downside is that those who want to hear HF broadcast signals in "Hi-Fi" want the audio spectrum to be opened up even broader than it is right now. You just can't please everyone.
I would encourage those who think the K3 is more 'noisy' to listen to both the K3 and the comparison receiver with a 3 or 4 kHz audio low pass filter in line. My ears act as low pass filters naturally and I do not perceive the K3 to be any noisier than other receivers. 73, Don W3FPR Brian Machesney wrote: > Gents, > > On the flip side, I - and, apparently, many other operators from whom > we've heard on this and other reflectors - have run the K3 for 30+ hours out > of a 48-hour contest and not experienced the fatigue you describe.
