Re: [Elecraft] New Elecraft K4 has great Rx Audio on CW pileups, no more mush

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 radi

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. Wayne > On Jun 23, 2020, at 9:11 AM

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 t

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! 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ . On 23/06/2020 12:41, Bob Wilson, N6TV wro

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 mad
