Hallo Guy,
The best way I think is to do a signal trace from the antenna jack through the
20m path towards the load speaker. You may use
A simple x-tal signal injector in order to have a signal generator.
Everythink else is just guessing!

Dear all,
those tutorials are excellent! By the way: You can hardly expect that you can
easily
use a oscilloscope without training and reading documentation.
And to make it even worse: There are much more complicated instruments like
network
analysers or logic analysers, where you have to
Dear all,
I am using the K2 DSP option from the beginning, which is (technically)
working fine. But I am constantly
switching it off, because it's swallowing weak signals (especially CW
signals).
I am using the default values of the DSP option. Does anybody has
experience how to use the DSP
Hallo Tim,
I don't think that you do have problems with the power supply. How do you run
the power test? Do you use
a dummy load with a SWR/ Powermeter?
Do you align the band filters for every band?

Dear Frank,
As far as I remember you will build and test the K2 first without options. If
everything is ok, you will install for example the KSB2. During that
installation you will have to remove solder bridges and a capacitor, but this
is described in the manual of the KSB2.

Hallo Dan,
you can create a rule within outlook, which moves every message containing the

into the bin.
Is the term knob something naughty?

Dear all,
this is an important point, because I became a little bit sweaty after
installing
the LCD, when I realized, that I don't have access to U1 anymore.
In the manual there should be a big warning: Check soldering of U1 before
installing the LCD itself.

Hallo Mike,
The only parameter I now is the tr-Delay Parameter in the Menue, but it just
should affect CW mode. I do not have any

Hallo Colin,
You are right! 300 mA is too high. I have been somewhere between 150 mA and 200
mA.
How do you measure? With the internal Amp meter? Compare with external A-Meter.

Dear all,
this morning I have spoken with a german guy who is living on a greek
island (maybe with the sirene women?!?)
on 20m and was able to record my transmission and he replayed it to me.
So the first time I heard my own trasmission using the K2 and it is
realy very good!!! The K2 has a
Hallo Tim,
it's a little bit imagination. The K2 is realy a nice CW machine mainly
because of the variable filters and the CW memory.
Sending wise I don't see a difference from any other rig. But I agree:
Since I am operating the K2 I am enjoying CW again.

Dear all,
I ran through the K2 filter aligment considering all your tipps and
tricks. I also adjuest the reference oscillator
on the control board again. My filter bandwidths are 1.5 kHz, 700 Hz,
500 Hz and 200 Hz (Filter FL1 to FL4).
I have used Spectrogram to align the filters. The settings
Dear KW2 CW operators,
yesterday evening I was running into a problem during CW operation with
the K2. I called
CQ using the 1.5 KHz CW filter on 20m and got response from a couple of
US stations.
The signals have been quite weak ( RST 33 ), but I have managed to copy
a call sign and
to give
Dear all,
would it be possible to get the K2/100 and KPA100 review from QST as PDF
file?
Many thanks in advance.

Hallo Brent,
I am member of the low power group ;-)), which have had some problems with
low power from
The KPA100 on 20 and 30m. If you are ending in a high current message on 20 not
reaching
the 100+Watts, than you maybe can join us. My cure has been to increase C80,
C81 in the
PA driver
Hallo Jonathan,
Welcome to the low power group. I was running into the same problem a couple
of
days ago. If the problem is just on 20m/30m and your are shure that you didn't
mixed the gray and black toroid cores, than add two capacitors parallel to
C80, C81. I have tested it with an other
Now I understand why the english and scots and wesh are sticking
to the pint!!
A pint is bigger and so you are getting drunken faster than in
Germany. And time is money ;-).
The big danger is mixing the metric with the non metric system.
Maybe you know that one of the NASA mars probes has been
Hallo Jonathan,
I have done the calibration last weekend and I am getting a SWR of 1.0-1 on all
bands. I have used the
build in dummy load of my MFJ 949E antenna tuner. I would blame the dummy load
too.
You can maybe carefully use a tuned antenna at low power levels just to verify?

Dear gentlemen,
I have two questions regarding the KPA 100 option:
1) What is the safe continuouse power level, which can the KPA 100
deliver for example for one hour?
2) How does the PA transformer work? Somehow the cores itself seem to be
the primary input of the
transformer?

Dear all,
last weekend I finished the KPA100 option, which is causing a little
problem. Everything
Is running well except power on 20m, where I just reach 50 Watts.
The QRP output is not affected, so I am quite shure that the RF path to
the antenna
through the LPF is ok. Just to be shure I
