Hmm, are Lyle's other irons in the fire being heated for Eric's other
fish to fry? :-)
More seriously, I also would love to see changes to the noise reduction,
particularly to help
with weak signal work. I'm not sure why anyone cares about noise reduction
for
strong signals -- I just turn down
The filter reset function (knob press) that selects NORM, NORM 1, and NORM 2
is helpful in getting the filter width back to a preset value which can be
different for each mode. It would be helpful, however, if the lower display
briefly showed the filter width after the knob is pressed. Right
- revert to .000 by pushing CLR+FINE, this simplifies coarse tuning on
round kHz.
- for European XV transverter users: Coarse steps 6,25 and 12,50 kHz(common
raster here for FM144/430)
- speed up tuning with factor x10 when spinning the VFO fast.

Regarding noise reduction and the BHI products; I've noticed that the BHI
ANEM works substantially better than the K3's NR. For whatever reason,
whenever I switch NR on, the band noise seems to get attenuated slightly,
but then reshaped to resemble noise in a tunnel. It's very tiring to listen

Wayne, I have thought about your unique construction technique and am
impressed with the results. When the K3 box arrived a year ago I thought:
Where's the case?
Lyle is looking at the NR code. Let's rest this thread for now.
We'll pop up here when we have something new to try. :-)

Rob,
I'm not saying that some logging programs and K3 control programs are not in
need of some changes but your problem could have at least been
avoided/circumvented by something that I reported to K3 support some time
back. CONFIG parameter CW WGHT was enhanced to provide a SSB+CW function

Hello all,
My K3 has been built for some time, and working quite well. However, I've
been a bit curious about the rear panel alignment especially as it relates
to the ground post and power pole connection. Those two never seemed to
line up right with the cutouts in the rear panel, while all

The 2D (where did that name come from?) fasteners are handy, but they don't
maintain much in the way of shielding integrity.
If you want decent shielding then you need continuous contact between panels
and a lot of screws.
You could always make your own, for example, here's a photo of an
Doug I use DM-780 and discovered the same thing you are experiencing once in
a while. I finally figured out what I was doing wrong. I narrowed down my
K3 filter to 250 hz and saw on the display that I was centered on 1500 hz in
Data A mode but when I switched to AFSK for RTTY it was centered on
Hello Elecrafters,
I just completed assembly of a W1 Power Meter kit. It seems to work well with
good accuracy.
For some reason I had a bit of trouble making good solder connections. This is
the first RoHS board that has given me trouble. It seemed like it took extra
amounts of time
With the help of Gary, AB7MY, of Elecraft, and Don, W3FPR, of this list,
I've just resolved the most crazy problem of my nearly 50 year ham
career. About a month ago, I decided to upgrade my K2/10 (#337) to a
K2/100. After inquiring here about how the KPA100+KAT100 in an EC2
enclosure might

I recently also completed the W1 with the W8FGU case and was at least as
pleased as Bill. I didn't notice any problems with the soldering,
however. I'm still using my non-RoHS Kester solder and simple Weller
single temp soldering iron that I bought 10 years ago to build my K2 #337!
Anyway,
Doug,
DM-780 appears to start with its tuning guides at 1415/1585, which does not
match any of the K3's RTTY pitch settings exactly, but is quite close to the
K3's 1445 Hz setting. With the K3 in AFSK A sub-mode, hold the K3's PITCH
button (just above the VFO B knob) to see the pitch displayed in

However, they apparently think CW is a fire truck.
I can safely say that for the many years I have on the job, CW is
definitely not a fire truck :-) Drivers
In my previous message I forgot to mention one other difference between AFSK
A and DATA A sub-modes. In AFSK A, the K3's dial displays the actual mark
frequency, whereas in DATA A the dial displays the suppressed carrier

Thus, to tune in the W1AW RTTY bulletins on 14095 kHz, in AFSK A

I have not had any problems myself, but some boards suck away the heat
from the soldering iron tip more so than others - and that is true
whether the boards are RoHS or not.
I routinely use about 750 deg F for soldering and bump it up to 800 deg
if the board traces are large or there is

Tom,
If you want smaller than the K3, the EC1 and EC2 enclosures sound like
what you may be looking for. Of course, they are K2 gray color, but a
bit of spray paint can change them to K3 black (but with a wrinkle texture).
Of course, there is alway the TenTec enclosures if the EC1 and EC2 do

Many thanks to W6NIA,NT6A,N5GE, AB7R for advice and suggestions, but still
no success. Finally went to Elecraft Utility, did a update and turned the
radio off. Sometime later I turned the radio on and it was on HP! All
operation seemed normal; it could be switched from HP to LP and then back
I just finished building a KX1 for a friend and it occurred to me that you
pick up a lot of information about the radio during the build process that
could come in handy as an owner/operator of the radio. Unfortunately this
information is lost if someone else builds your KX1 or if you buy one on
And strangely, this problem will never trouble you again I hope
so, anyway.
