Unfortunately, there IS a problem w/ CW audio in the K3, at least with both here (see concurrently running thread: K3 Audio Low Pass Filter). The sidetones generated around the 12 kHz DAC leak-through (+/- sidetone frq., ie. 500Hz)are clearly audible for me and rather annoying, enough so that I had to insert inline low pass audio filters on each radio to knock it down to make CW operation tolerable. I was in correspondence about the issue back in Oct/Nov of last year w/ Elecraft.
Regardless of the "60 db down" and other levels people have measured on those sidetones, I can hear it, even with as low a volume setting of around 9-10 o'clock. Apparently there are others that can as well. The majority of folks who own a K3, presumably yourself included, have a reduction or loss of hearing at high frequencies. From that perspective, the audio is great! However, not hearing it doesn't necessarily mean there isn't an underlying problem present, and those that wish to fix it aren't doing so out of "desire to tinker and change things." As for SSB/AM, I couldn't comment at length on the audio quality, as I just don't operate or listen up the bands much. But from limited operation, I'd concur that the audio was fine. 73 Eric NO3M Ron D'Eau Claire wrote: > I'm quite happy with the K3's audio as originally designed. > > Other Hams who have heard my K3 and, non Hams too, think it's great.
