Hi, I also use NR on CW and agree it gives a nice reduction of background noise, but also notice a very annoying issue:
Intermittently, there is a click in the headphones output signal. It happens whenever I have NR switched on (even on a mild setting, like F1-2). It most often occurs just after I've finished sending. Then, the receive audio is diminished for a fraction of a second, followed by a quite loud click. This issue does not happen all the time, although I can fairly well reproduce it within one minute of trying. The issue is independent of my AGC settings (fast, slow or off). I can also reproduce it when I use TX test mode. And also with sidetone volume set to 0. It's not related to the QSK settings, as I can also reproduce the issue with the K3 set to semi-QSK with the delay set to .35 seconds. With the K3 on speaker, I can hear the diminishing of the receive audio, but not the click. I've made a recording of it via the K3 Line Out with Audacity. On the recording you can see and hear the diminishing audio, but not the click. Anyone else notice this?
