All,
Over the years there has been the odd thread about tin-whiskers, so
the following may be of interest.

You are not alone regarding problems with ANF (NTCH) distortion of SSB
received signals. Too bad the problem continues unaddressed - as it is
the single remaining receive issue I have with my K3.
There is a thread about it here:
Ed,
You probably already now this, but other K3 or KX3 users may not. Until there
is a single command for changing between the K3's front panel mic jack, the
rear panel mic jack or the rear panel line in, the way to make the switch is to
use one of these macros.
Mic Input - Front Panel:
The hearing in my right ear is weak. I use the CM500 headset. Using just the
Main RX, I find that my left ear is doing all of the heavy lifting. Lately
I've been using the SUB RX in Diversity (with the main antenna) so that I
can offset the stereo balance. By applying more SUB RX volume I am able
So far no adjustment, but hopefully a future option?

Fascinating, as are the comments following the article. The removal of metallic lead from
electronics that should be recycled anyway, in return for a large increase in failures,
does not seem to me to be a good deal for civilization (some of the comments mentioned the

As far as I know, there isn't. I've suggested that the CONFIG option (SUB AF = BALANCE)
that makes the sub volume control into a balance
control also should cause it to be a balance control for the main receiver when the sub is
off or not installed. I don't see a downside, but I'm not the
Hi Joe,
Is the K1 still available?

Does anybody know what value and which pin to check on U1 on the I O

The other day as I went to sit down after a short break I too saw a
flickering TX light and thought Oh Oh then while I settled in my
chair my foot tapped the foot switch and it stopped. issue here with
the foot switch.
Since its keying CW do you have a straight key or bug installed? a
Further do David's suggestions - do you have an RS232 keying circuit keying
the K3? If so, a component in that circuit could be starting to fail.
Just a thought ...

My hearing is OK, however I do find that when AFX is enabled in my K3 the
audio is always unbalanced, ie louder in the left channel to such an extent
I don't like to use the AFX much.
I've always thought an AF balance would be useful, at present this is only
available when the Sub RX is active.
Thanks, David et.al.
You're right. I've been using the Keyspan driver for the K3 Utility. I
never bothered to reload the FTDI driver after I did a clean re-install of
the operating system.

Paul,
One possible explanation is if you currently have CW Keying enabled via your
COM port AND you had just turned on your computer prior about the same time
as turning on the rig. Your computer COM port randomly fires DTR/CTS
signals on power-up which would present itself as you describe.

Re Speakers and the KX3 and the KX1…
Has anyone considered the speaks used in the iPad, iPhone, iPad Mini and the
iTouch?
The iPad speaker sounds darn good!
I am about to pop the top on an older iTouch that has a built in speaker… Its
sound is so so but maybe it would work for the KX1…
Ideas….
I do hope so.

Hi Art,
Try this:
The error message ERR IO3 often means that the RS232 serial interface
chip on the KIO3 board has failed. This may be caused by a static
discharge or nearby lightning strike. The chip that fails is U1 on the
KIO board, as shown in Figure 7 25. Here is a procedure to check U1.

Interesting ideaI did that in a speaker mic that I used on an HT

than the original.My only worry is the original speaker used and its
magnetic shielding may be important.If I replaced it would I be

The auxbus connection on the ACC jack seems to be open.
This is the one that always gets folks... This trouble is 95 percent
something not in all the way. The other 4 percent is breaking a wire or

Well, RM, it's almost certainly something in the interconnect cable with the
DB connectors running from the K3 to the KPA500. That's what moved as you
connected the keyer.
Since you checked K3 end, have you checked the KPA500 end? Are both
jackscrews tight?

I'm a freelance writer who has been writing manuals for Elecraft for 11
years, so far. It's not lost on me that many of the engineering staff are
the same folks who I worked with on my first Elecraft project back in 2001.
They have grown significantly over that time and have added a number of

Getting an automatic AT, for me, was kinda just a laughing point.
