Why off list? This is of interest to all K3 owners and the
experiences/expenses of others is very relevant.

Well, most of the update can be done by the user and I did them myself.
Elecraft gives a webpage of the modifications:

They also provide the necessary parts with clear instruction and at reasonable
prices:
I use serial device servers in remote stations. The ones I use from
Lantronix allow you to also connect via telnet. I have never tried using
them that way, but I would assume that this would solve your problem.

Hello all, picked up a new KX3 yesterday from my local emporium, slightly
annoyed by the awful noise the VFO knob makes rubbing on the felt washer to
provide the spin resistance, so I came up with a mod to improve this
dramatically.

Hi Gary,
Some of the hardware mods correct problems or prevent problems and they
aren't noticeable after installation. But they provide peace of mind and
increase resale value.
One mod that I found useful was the one that corrected noise while tuning
the VFO. It improved operation on 6 and 10

You may have a menu open. Tap MENU. VFO B should show a frequency unless
you have a menu open.

I'm sorry, it's probably the DISP button rather than MENU. MENU also
changes VFO B, but not to the things you're seeing. Those are DISP
functions.

Good Morning, this is Mark Griffin and my call is KB3Z. I am having some real
issues when it comes to getting a reliable SWR reading between my K3 and an
external Wavenode Meter. I hooked up my hexbeam directly to the input Antenna 1
Connector of my K3 and got the following SWR readings in the
In the past I have looked up various problem fixes in the Old Elecraft

I would appreciate suggestion as to how I fix my K2 low power problem on 12

You will get lots of responses to this. 99.9% of the folks on the

I have a similar situation with a WM-2 wattmeter and my KX3. Here's how
I stopped worrying about it:

A better way is to connect a load with a known SWR.
Using a BNC-BP BNC Male to Stackable Binding Posts with three 100 Ohm
1W resistors in parallel, 33.3 Ohms, SWR should ~= 1.5.
Directly connected to the K3, ATU in bypass, 5W output, measured SWR = 1.1.

Congratulations on your excellent hearing, Pete. Yes, it can be a curse.
Also, I envy your obviously silent environment. I wish I could have that.
Good for you that you found a solution to your problem, and it sounds like a
very good one too.

Since you mentioned a pot to adjust, what is the chance that you
increased the value of R98 (on the bottom of the RF board) above its
normal value of 270 ohms.
That resistor is sometimes increased to provide more rapid settling time
for the power control loop (particularly in TUNE),

Hi all,
My K3 is a #1255.
I've done all the mods myself. I'll give you a roundup of that , with
the results:
*Solving a problem:*
- K3 Synth ALC = That was a really necessary one, I had that problem and
it needed to be fixed
- K3 external ALC Mod = Necessary since I started to use ALC
Good Afternoon,
I have been busy writing net reports and logging all of the data
from each of them. It is very soggy now, typical Oregon fall weather.
It tried to snow but never quite got that cold.

John, the problem is that I don't have one of these. But thanks for the
suggestion. One thing I have not tried is hooking up my antenna and external
wattmeter coupler with Antenna 2 instead of Antenna 1. I am anxious to find out
if I get the same readings with #2 as I did with #1. I guess I am
Mark,
There is good reason (assuming the internal tuner in the K3) for *not*
syncing the wattmeters.
With the KAT3 in-line, the SWR is *not* reading the SWR on the feedline,
but instead telling you the SWR at the *input* to the KAT3 - that is the
load that the K3 PA sees, and that is what
Mark, the numbers you quoted look pretty typical for SWR meters. They are
*not* precision instruments, nor do they need to be even in commercial
applications.
Within the range of error you reported, there will be no difference in how
your K3 and antenna work.
Power measurements are no better.
Did you make the VFO tuning noise reduction mod, Arie? My tuning noise was
very bad until the mod was applied. It certainly made a lot of difference.

Most ham-grade Wattmeters/SWR Bridges that I've encountered read E,
assume R, and calculate P in an analog fashion. When SWR is not 1:1,
Z is not equal to 50 ohms, and in most cases, the higher the SWR, the
higher the power indicated on the meter. For these instruments, nothing
