Thanks to everyone who offered educated thoughts on my problem. I just
discovered that the problem apparently lay in my USB hub, perhaps as
simple as a loose connector. I plugged the USB cable into a computer
port directly and voila! So I now have frequency control communications
again.
How difficult is it to replace (realize I am challenged in the delicate
touch department) whatever board in the K3 does the serial
port/interface to the radio?
Is it likely a go back to the factory thing or an easy desktop job for a
klutz (me)?
The reason I ask this is my K3 suddenly seems
I seem to have the same issue with my K3 I/O board.
I have a temperature controlled heatgun and will try to solder out the
IC if it turns out to be true AND if i knew what temperature to set it
to. Anyone?
Mry xmas es hny.

Before you try this on your K3, get a couple of old computer boards
(junk motherboards, expansion cards, etc) and practice on them. Only
when you can remove and / or install components from the junk boards
successfully should you try the same with the K3. Just my 2 cents worth

Thanks, Elecraft Reflector friends! Thanks to MontyS, Matt Zilmer, and
Howard Stephenson, I have the K3 serial port working once again! Howard had
me check the voltage on pin 8 of U1 on the KIO3 main board, and it was less
than -5V (about 120 mV) with the serial cable plugged in. This was the
Thanks to all who responded. Turns out I have a bad KIO3 board.

One thing that often goes wrong to kill RS232 is different speed

John,
That is actually up to the user to determine. It does require an
interim intelligent device.
Check out LP-Bridge or several other serial port sharing applications
that run on your PC.
The K3 is a terminal device, it does not provide control for all RS-232
based communications. Refer to

Yes. The advanced settings have nothing to do with the RS-232 control signals,
Bill, even if you make BIOS changes to a port it won't affect the
port's operation under Windoze, since it's all controlled by a kernel
mode driver.

Thanks for that info, Matt. Did not know that.
No controls in the BIOS anyway. I'll just have to live with it I guess.
Fortunately, I can use VOX for TX control and don't really need to use the
RS-232 control signals.

I have never used VOX. Why would you need to? If you have a fully

Julian et al.,
I have always used VOX for WSJT keying, so I tried setting it up
It may be a too obvious comment, but the easiest way to tell what is
going on is with a serial breakout box. If you get one with LEDs you
can visually watch the status of the control and data lines in real
time.

a free download from Eterlogic's web site. You can create a serial port

I use it to run DXBase 2007 and DXLab's Commander program
