[KX3] Key Clicks

I'm not sure what I've done. Not sure if I just woke up and noticed it
or if I've done something that's caused it.

With my KX3 terminated into a dummy load, split and dual watch active,
VFO B 1 - 5.3 kHz up or down from VFO A, filter set to 450 Hz and
centered, I am getting key clicks on VFO B. NB and NR are off.

I did a little reading through past posts and even reverted back to FW
2.18 and then 2.12. I also reloaded a configuration from 8/31/2014 and
still hear the key clicks.

I do *not* hear key clicks if both VFO A and VFO B are on the same
frequency with split and dual watch active.

The key clicks occur on every band from 80 - 10 m.

I also noticed something else trying to work W1AW/5 on RTTY - terrible
ringing. He was working split up 1 so I don't know if that was the issue
or not. I have not tried to recreate this using a backup config or
different firmware.

My question(s) is/are:

Does anyone else notice this or is this an issue with my rig? If it's
me, what on *Earth* have I done to cause this?

On a side note, despite the "end of the world" CME, the NA-SOTA weekend
is happening this weekend. Get those great Elecraft rigs on the air and
help those guys and gals out on the summits. :)

73/72,

Re: [KX3] Key Clicks

John,

Thanks for the tip.

I have a hard time filtering the F.O.D. on the KX3 Yahoo group. I'll go
back and look there too.

I have set the DLY and finally got it where I can tolerate the key
clicks, but the DLY is set to about 0.20 - basically, it only clicks at
the end of transmit.

I *did* notice that even with my MON turned to 0 I still hear key clicks
in my headphones (I have been wearing headphones the entire time I've
been testing). I hear them as the rig stops transmitting.

I'm going to jump in here with my 2 cents worth, because I would REALLY like Elecraft to clean up
the QSK on the KX3.

Recently I've been noticing annoying pops in the speaker when sending CW. Maybe they've always been
there. I never noticed them before. It's been a while since I installed firmware, so they must have
been present but ignored for a while at least. They really jumped out at me when I started playing
with a new sideswiper paddle last week.

The pops happen at key-up, not key-down.
They are heard with the internal speaker and also with external speaker or headphones.
The pops are present when using the internal keyer, with an external keyer, and with a hand key.
If I send a series of dits while varying the keyer speed (with external keyer), the pops are most
pronounced around 19 wpm.
My KX3 is S/N 77, on FW 2.11.
Dual watch is not active. RIT and XIT are off.
My AFX mode is DELAY.
My QSK delay is set to 0.01 to try and reduce the QSK thumping.

Re: [KX3] Key Clicks

I have the same problem with my KX3 serial 0325, uC=1.5 and DSP=1.21. I
never really noticed it until I abandoned paddles and reverted to bug
and 'swiper operation. It's not impossible; just "unpleasant" so I turn
down the AF gain with my left hand when transmitting.

It may have always been there but paddle usage doesn't really require
the concentration that bug and 'swiper use demands to achieve proper
spacing and timing.

Anyway...that's my two cents.

I played around in the SKCC WES for a couple of hours this weekend. I
noticed something odd (to me at least) about the key clicks:

If I turn my power supply *off* and just run off the internal batteries,
the key clicks dissipate. They don't altogether disappear, but they do
diminish. It's "less bassy" if that makes sense.

The PS I'm using is an MFJ-4125 switcher. I don't have my Astron RS-35A
hooked up at the moment. If I get a chance to play around with it this
afternoon, I'll see if it sounds any different with the Astron.

Re: [KX3] Key Clicks

I run off batteries 100% of the time, typically around 12.6 volts. I hear clicks.
