[Elecraft] KX3 Headphone Clicks

You are right. It doesn't help me. For me it all comes down to how much background noise there is. So for me it helps both with NR and NB as they both reduce the noise. When the QRN/QRM is above S6 I have to turn the AF gain down to 1. I still can here the signals, so for me it's no big problem. But I hope to get rid of it all in a future F/W version.73 de Hal

I tried various things, including adjusting the lower three audio equalization bands, using a lower NR setting, setting the receive bandwidth to 100-300 Hz, setting NB on at a low setting, and using a non-zero QSK delay. In my situation, there was but one thing that just about completely eliminated this clicking: turning OFF the NR. With it turned on, at level 1, the clicking was ugly. Increasing it up to 9 or 10 helped a little, but lowered receive volume too much. Turning NR off stopped my clicks.

When I've got headphones plugged in and running full break-in I'm hearing a fairly strong clicking noise. I set the rig into semi-QSK with a 1-second DLY and see that the click is happening when the radio goes back into receive, NOT when I key it and send RF out into the ozone. Any idea what's happening here? I've tried it with three different sets of 'phones: A Sony MDR-V6, a Bose Triport, and an el-cheapo pair of 'round-the-ear phones that I use with my iPhone at the gym. I hear the same click on all three. I then unplugged the 'phones and listened to the built-in speaker with DLY at zero. The clicks are there, too. Very annoying. Any hints??
