The measurements that have been made seem to suggest that the problem is not regular distortion or clipping. I am wondering if it is some kind of quantisation effect due to the fact that the signal processing is digital or analog? I am thinking of the fact that there are people who claim that vinyl (analog) LPs sound better than CDs, and FM radio sounds better than DAB.
Personally I find it hard to understand what the complaints are about. SSB signals usually have quite a lot of distortion in any case, due to compression and ALC and the fact that they are transmitted through an amplifier whose response would certainly not be described as "linear" by any hi-fi buff, not to mention any multipath distortion effects introduced by the ionosphere. It's hard to imagine what the K3 could be doing to the signal to make it sound worse. I just don't expect hi-fi audio when listening to the ham bands. Perhaps the K3 is allowing you to hear the original signal "warts and all", much as a top-end hi-fi would make recordings that were acceptable on average equipment sound unpleasant? I do find the K3 audio to have rather too good a frequency response, and so on mine I have used the RX equalization to cut the topmost frequency by -16dB and the next one down by -8dB, which to my ears gives a much more restful sound. ----- Julian, G4ILO.
