I had the same problem - turned out to be noise from the computer (I
was using the USB CODEC for audio in/out to the computer).

Louis,
It goes away in TX TEST. So I suspect it is an RF-in-the-shack problem.
Try the K3 into a dummy load to verify that assumption.
If it is OK on a dummy load, your best fix is in the antenna system -
better baluns, check antenna connections and anything else that can
cause common mode

My Upgraded K-3 has a noise when the transmitter is keyed. The noise sounds
like either some type of data noise or a severe feedback The noise is there
the moment that the radio is keyed, no type of voice input needed. I have
checked all settings and can find nothing that is out of spec. I
I believe that if you look at the kit assembly manual, it will reference the
installation of these items at the appropriate point during assembly. The kit
manual is available from Elecraft website as PDF.

Hi Geoff,
I have built two K3/100s and one K3S/100. All three with a KAT3/KAT3A.
Knowing how tight it is putting in the KAT3/KAT3A, I would install that
first. Then the KPA3 and the K144V last.
I have never installed a K144V, but I suspect you have to install the KPA3
before the K144V.
Mark,
Bret, Don brings up a great point if you don't have a frequency counter.
Per Don's suggestion you could even get very close if you zero beat your K3
to a WWV carrier on 10, 15 or 20 mhz. This is really easy to do with the K3
reference offset setting in the Config menu...
Tune into the WWV 10mhz
Perhaps a simple question but I am a new Elecraft user.
I have a 10 Watt K3S, (obtained pre built) together

Is there any preferred order to
If you do not have a frequency counter, there is another way.
Use XG3 Utility to set the XG3 to provide a 10 MHz output.
Listen to the 10 MHz reference in your receiver in CW mode and peak the
signal at your sidetone pitch. Then listen to the XG3 without touching
the receiver. Adjust the XG3
Hi, normally, you would drive a frequency counter with your 10mhz GPSDO
output... i.e. you need to have a frequency counter that accepts a 10mhz
input as a reference. Then you would measure the output of the XG3 for any
given frequency and adjust the parameters in the software that programs the

Mark makes an excellent point but a special anti-static pad is not required
for a simple procedure like this. However, simply unplugging and replacing
the FP does not require touching anything inside the K3, so there's no
danger.
If you need to touch the pins on the connectors or anything inside

When I had K3 serial #3505 in for upgrades, it had the old pins and they
upgraded to the gold pins and didn't charge me for that part of the service.
The support folks told me the change to the gold pins was somewhere just
over serial #4000. They did not know the exact serial number.
I agree with
OK - thanks Rich, Don & Kevin.
1) COM3 was my XG3 RF Signal Source USB Serial Port - silly me...
2) PC Sound Card is now Default - I had to plug something into the Blue Line

3) Nothing in K3S Line In jack; U7 card
Guy is quite right about the pin issue, however I have an early K3 with the
original pins and it works FB after 9 years.
To be absolutely sure it isn't something external to the K3, first I'd
disconnect EVERYTHING except the main power cable, and see if the problem
persists.
Next I'd remove and

In the K3 there are a few digital lines from the front panel which carry
multiplexed information to the CPU. The only way I can think of that would
scramble unrelated front panel input according to your report is that the
multiplexed line is malfunctioning and screwing up the data stream into the
Re: Loctite:
I'd suggest Loctite 'Purple' (222). Still accomplishes the task but much easier
to adjust/disassemble later. Especially important with small fasteners and
tools.
If you're installing 6mm, 8mm bolts on your car, Blue is likely the best choice.

That should get past the MCU LD on the LCD screen.

Hi all, New to the whole Elecraft scene.
Just acquired my first K3 and its serial number is 07126.
I have been experiencing some strange behavior while rotating the VFO
whereby the radio would change bands unexpectedly. On occasions, the rig
will jump to a supposed frequency well out of the
Both Rich and Don have given good advice.
Make sure the U7 or onboard NVIDIA sound device is set as default so you
don't broadcast windows sounds. Make sure the USB Audio Codec Speaker
and Mic are enabled but not set as default. In the WSJT software select
the USB Audio Codec as the sound
An additional "By The Way" comment - Windows normally sets the last
installed soundcard as the default. Your U7 soundcard was likely set to
be default when it was installed.
You can set the default back to the internal soundcard (the NVIDIA) if
you are trying to use the U7 with LP-Pan2.
73,
Bret,
Do not set the K3S CODEC to be the default soundcard - the default
soundcard will be the one that plays sounds from the OS (Windows
Sounds), and those sounds should not be transmitted on the air.
The "Recording" setting level is audio from the K3S to the computer (not
K3S recording).
1. The U7 is not on COM3. Sound cards do not use serial ports. Perhaps COM3
is a virtual COM port created by LP-Bridge, or perhaps COM3 is the K3S's
USB serial port, and COM7 is a virtual port created by LP-Bridge that you
connect other software to. You need to get this straight for other reasons,
Kevin,
I do find the Serial Port for the K3S as COM7, and also have a ASUS Xonar U7
external card on COM3, running through a LP-PAN2 I'm also working to
configure. That's a somewhat separate topic.
I have several sound cards, it seems. My Windows 10 PC Device Manager lists:

Hi Bill - We might be talking two different things. WSPR & WSJT-X have an
option under band hopping to send a 2-3 second tune signal before each RX so
that an ATU can recall the tune parameters for that frequency from memory.
That's not happening for me.

Hello
I have just discovered that I have a trouble with my KXPA100 on 20m, and
only on this band.
The set up is a KX3 connected to the KXPA100 using the internal ATU of
the KXPA100 ; the fault occurs on the usual antenna (a 2x20 doublet +
450 ohms ladder line) or with a 50 ohms dummy load.
