Something I thought might be helpful for builders and other techy/service

Last week I was working with a student in one of my computer classes and we
were involved in fixing a MB that was having a thermal shutdown problem with
the CPU.
It is a late model device with an Intel P4 3GHz
If you've got 100Mbps Ethernet in your house, you're probably already
hearing noise around 14.031, unless your antenna is far, far away
from your networking equipment. It's not just the cables, but also
the routers and interface cards that seem to spew this stuff!

Part of the K2's success must be attributable to how well the company and
community have adapted to changes since the K2 was first produced. No doubt the
foreseeable future will bring even more changes.
Speaking for myself, the K2 and

I used Kester #44 .020 diameter for my K2.
I only use RS solder on Pl-259's.
Get to the Elecraft site and have a look at the recommended solder
stations. I bought the Hakko 936 when I started the K2. I think a

I used RS .032 60/40 on my KX1 and it worked fine. The only problems I
had during my KX1 build were not related to soldering (i.e., messing up
the windings on T1).
The product number is 64-009 E.
It might not flow as well as the 63/37, but I was happy with the results
and didn't have any
All has been well up until now, including setting the
bias per instructions. Without PA's my bias current
was 330 mA, so I successfully set it for 730 mA with
the PA's.
I had adjusted R26 for 5w and got the VSWR sensor
zeroed. During my high power test (into a matched
antenna on a clear
Some builders prefer other alloys that contain silver, etc. Be aware that
they do not all have the same melting temperatures. This could lead to
frustration, damaged boards/components, or also a better solder job. Just check

In looking at the K2 schematic, it occurred to me that you could take

There are three menu setting that affect the LCD display.
1. LCD brightness (backlight brightness)
2. LCD Adj - Used to optimize the display when viewed at different angles
3. LED brightness - used to adjust the LED brightness compared to the LCD
background brightness
Hope this helps.

Don,
I am not certain what you mean by 'view the display in LCD fashion', BUT:
The LCD Backlighting intensity is adjustable - also the LED brightness
is also adjustable. Wayne demonstrated that several times at Dayton.

I believe that Wayne indicated that the LCD is transflective, so it
will be viewable with or without backlight.

Good Evening,
Another fun couple of nets. Twenty meters was pretty good but the last
minute switch in frequency to avoid the very active contest may have
thrown many of you off the trail. Sorry but there was no way to get on
the air anywhere near 14050 kHz since it was wall to wall
Great, and good photo.
The thing is, on a radio of this type, the LED LCD backlight current
draw is not that significant. (DSP's take some current, this is not a
K2 in current draw). However, in sunlight (or flash camera) the
transflective display remains viewable.

The 63/37 is what is called eutectic solder because it has a very sharp
melting temp dip at the eutectic temperature of tin/lead alloy. It can be

to solder with because it has almost no pasty state going almost directly
from liquid to solid. Its primary use is for rapid soldering
