Hi all,
K2 #5408 is alive in Poland and sounding great.
I still have the KSB2, K160RX, KNB2 and KAT2 options to go in.
I bought kits in QRP Project, Berlin, Germany 2nd May 2006.
See you on the air.

Just installed the K2 VCO Shielding Upgrade. The instructions say to
disconnect he frequency probe and completely remove it from the K2. I used
to leave it in TP2. Does it really make a difference with anything by
leaving it in TP2?
Tnx

Ouch,
25 wpm is cw with training wheels. In the real world people don't send
that slow. Bummer.

Ouch indeed :-). My fastest reliable speed ever is about 25 wpm. It's
almost embarrassing to say I've been 90% CW for 15 yrs and my speed
Hello All,
I just added the DSP processor to my K2 and adjusted both the DSP and
XTAL filters to the same center frequency using Spectrogram. The DSP and XTAL
filters work fine together, except that when using the default filter settings,
the DSP and XTAL filters essentially duplicate
It's still going to matter, if you are running AGC or there are strong
nearby signals. Run your CW filter at 400Hz for any narrower DSP setting.

Then, when I want the wider bandwidth, I'd use one of the XTAL filters with
the DSP filter set to LOPASS, and when I want
Something bugs me about the implementation of DSP filters. It seems
we're using DSP to duplicate crystal filters by having them do bandpass
functions. The other thing we do with DSP is noise reduction which I
hear works best at wide bandwidths so the algorithm has some noise to
work with.
But
Last week there was a thread about this. Leaving the probe in increased some
spurs in the transmitter output. Values were not given, but it sounds
removing it is the better idea. When you are done tweaking the filters take
it out.

Hello All,
I wanted to comment on the Jackite Poles. I recently bought 2-31
footers from Jackite and they are awesum. So was dealing with the
company and they were shipped fast. Recently I found a dealer on ebay
selling the exact same thing and after SH are added, theirs are
$7.00 less on

My preference is to use the 700 Hz xtal filter and then narrow down the
bandwidth with the DSP filters when necessary.

As the noise grew worse on 40 meters this Sunday I called more slowly. Working
in that manner allows for fewer repetitions. Higher speeds are fun but only
when the other op can copy you. Any hint of problems means I should slow down.
Hopefully the other op will do the same.
Kevin.
Kevin,
With all due respect that is a non sequitor. There is a distinct difference
between net operation and the rough and tumble world of DXing. The former is
based on cooperation, and the latter is all about competition.
The origional post was about achieving optimal QSK performance, but
Guys - Lets kill this thread for now before it takes on a life of its

Hello again folks,
I seem to still have that black cloud hanging over me as I finish the
basic K2 #5061.
I am finishing the calibrations and adjusting the L's and C's in the
bandpass filter section. I had 1 1/2 problems remaining. All the
circuits tuned properly in receive mode except the 30
Hi all,
I deleted my messages playing with a spam filter program but I think someone
just asked about adjusting the digital filters on the K2.
The audio digital filters are sharper and narrower, and the IF crystal
filters will cut out adjacent interference in the IF section, thus
preventing
I did the same but entered Jackite 31' and found that they also have black as
well as orange.

Pat,
Additional questions:
1) does L8 peak properly?
2) How far down is the slug on L9 with the added 39 pf capacitor?
The tuning slugs are normally only a couple turns down from the top - if
yours are more than 3 turns down, something is wrong.
Since the bandpass L9 showed a peak on 30 meters
The items are still for sale.

to free up some assets to try other avenues. My K2 has never been

I'd say a majority of the people working REAL high speed are
doing it with keyboards and readers. (What's the point in that
when there is PSK31 to do the same job?)
A few hams out there can skip along at 30-40 WPM but they are in the
minority by far. Contesters don't count as they are locked
Pat,
One further check - RFC7 (15 uH) and C104 (68 pF). This is a series
resonant circuit tuned approximately to the IF frequency - if for some
reason these 2 components are series resonant somewhere around 12 mHz, it
could reduce the 30 and 20 meter signals significantly. As a quick check,

I have had the basic K2 up and going for a while, and have been using it
while I build the KPA100. Got the KPA100 built and all the inital tests
were fine on RX. I came down to the shack today (school club statio) to

I'm planning a short DXpedition to a 220V country.
Does anyone know of a quiet switching power supply
that would run on 120V 60Hz and on 220V 50Hz?
I'm leaning towards a QRP operation, requiring a
smaller supply, approx 5A at 12V output. However,
since this is likely to be a once in a lifetime
Here are my voltage readings taken from everything on page 23:
U1 pin 1 - 1.35v
U1 pin 7 - 1.97v
U1 pin 13 - .00
U1 pin 14 - .6
U1 pin 15 - .4
U1 pin 20 - 1.2
U1 pin 27 - 2.0
U1 pin 28 - 2.0
U2 pin 10 - 13.4
U4 pin 1 - 13.4
U4 pin 11 - 1.4
U5 pin 1 - .05
U5 pin 7 - .05
U6 pin 6 - .01

It's usually not very difficult to find transformers that will bring the 220V
to 110V for your equipment. They come in a variety of sizes, depending what
power capacity you need. You could then use a power supply you already have,
needing at most an adaptor for the plug type.
Granted, that
It's less expensive if you go here:
