I think the point of the recording was to illustrate receiver recover between
elements while sending high speed cw.
I would like to know how much better is k4 than k3, which would mean hearing
more between elements of cw at high speed; a better recording is needed or one
has to operate the

Paul,
The K4's DSP smoothly ramps audio up/down during muting. There's no "clamp."
The artifacts in the recording are not coming from the K4; they're probably due
to RFI getting into the external recording device's cables, as Bob mentioned in
his posting.

Just sounds like the audio muting during key-down. The K4 speaker
probably rolls off below 300Hz while your recording has higher fidelity.
External audio devices would have to roll off the low frequency to avoid
it. I bet if the K4 used a VCA rather than a simple clamp you probably
would not hear

I certainly hope the clicking I hear on the sidetone is an artifact of
the recording process, or something that will go away with the
production version of the K4!

Listening to the recording, I find the thumping during xmit very annoying.

Summary: The K4D Receiver Audio and QSK performance seems outstanding --
I'm sold.
I hesitated to order a K4 until I could hear how one sounded in "real
world" pileup conditions, compared to my trusty 11-year old K3s (S/N 1494
and 1495 with KSYN3A upgrades).
Well, here is a short recording I
