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??

Re: KX3 Headphone Clicks

Yes, this is a known issue. Try to turn down the AF gain when keying. That will make it much better.73 de Hal

Re: KX3 Headphone Clicks

Just spent an hour or so working with Howard and Wayne at Elecraft trying to nail this down. 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.

This may or may not help with YOUR particular rig's key click problems, but it fixed mine until they have a firmware resolution.

Thanks to the guys at Elecraft for their continued excellent support!!

Happy New Year to all, and may 2014 bring you the goodies on your wish list. (I already got mine - KX3, KPA500, & KAT500), so I'm pretty much outta luck this coming year!!! :-)

Re: 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

Re: KX3 Headphone Clicks

I thought that the clunks were due to RF interference!

If they are down to a problem that Elecraft knows about, like the poor
speaker performance, then I'm not greately impressed as I use headphones to
avoid the speaker problems...

Re: KX3 Headphone Clicks

Dave,

What I'm having are not "clunks" - they are truly "clicks". And they happen when the KX3 returns from a transmit state to a receive state. I hear it with the external speaker somewhat, but more so with headphones turned on. This is probably due to the fact that there are other "things" in the room that I'm hearing, while with the cans on my head, I hear nothing but the KX3. And in my case, I can remove those clicks about 99.9% by turning off NR. I'm pretty confident that Wayne & the crew will have this one resolved pretty quickly.

Re: KX3 Headphone Clicks

What I'm hearing is probably the same thing, except I dont have NR switched
on...

I'll read through the list of things to do to reduce the effect and see if
any work out.

This is probably due to the fact that there are other "things" in the room that I'm hearing, while with the cans on my head, I hear nothing but the KX3. And in my case, I can remove those clicks about 99.9% by turning off NR. I'm pretty confident that Wayne & the crew will have this one resolved pretty quickly.

Dave - what happens when you turn on NR, say at level 1 or 2? Do you hear clicks in your headphones on the transition from transmit back to receive?

Re: KX3 Headphone Clicks

In reply to this post by Reginald J Mackey SR-3

Just for grins, I tried exactly the same test on my K3, same antenna, same band. No clicking. I'm hoping the engineers come up with a correction in the upcoming few weeks. I can live w/o the NR being turned on for now. Still getting familiar with the KX3 (mine is only a week old) and finding it to be a really fine rig.

>> With your RF gain turned down a little, and the AF turned up a little, AND your NR set to level 1 or 2, do you hear any click on transition from transmit to receive in your headphones? I've use three very different sets of phones and still hear this. When I turn off NR, the problem goes away.

I hear it with the external speaker somewhat, but more so with headphones turned on. This is probably due to the fact that there are other "things" in the room that I'm hearing, while with the cans on my head, I hear nothing but the KX3.
