Betreff: [Elecraft] KX3 Headphone Clicks

Hi All - just this past weekend completed building KX3 # 5539. Seems to work fine except for one thing. 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??
