Sorry guys, I was mistaken about this. I just tried to increase power
and it does, indeed, go to rated power if you drive it with 29 watts.
Sorry for the confusion.

This turns the VOX off on power-up to prevent keying.
Speaking of power-up, would it be possible to add the facility to run a
user-specified macro automatically at power-up? (As an option, of
course.)

Lighting is one of those things that keeps on giving in many ways as far as

items and it fixes the problem for now, it's the thing's that it weakens

Yup,
When I worked for Sperry Univac we used to call that reducing the mean
time between failure. Not just lightning though, not following anti-static
precautions can have the same effects. The kit doesn't last in working
condition for as long as it should do.

Tommy,
You are going to need a K2PAKIT from Elecraft. That kit includes a
matched set of PA transistors (replace both) as well as replacements for
Q11 and Q13 (also replace both). After you install Q11 and Q13, but
before you install Q7 and Q8, check the voltage on the base solder pads

What normally happens with a static surge on the antennas is that the

There is another mechanism in the MCU that helps do that, but it is not

It must be set to 3.50 Amps for a K2 with a KPA100, and often the K2

Hi all,
As you may know, the KX3's NR (noise reduction) can only be adjusted in the RX
NR menu entry at present. There are three parameters (beta/B, decay/D, mix/M),
and these are stored separately for CW and voice modes.
We will soon be adding single-knob control of noise reduction. That is,
Greetings to Group:
I have the sad news to inform all that Phil La Marche W9DVM passed on April
14th. from complications due to a case of the stomach flu.
Several years ago he posted a request on a local reflector group looking for
someone to do some tower climbing, antenna work and odd
I'm very sorry to hear of Phil's passing. My condolences to Diane and
Phil's family.
I'm sure you'll be able to operate that dream station in honor of Phil's
true spirit and make him proud.

I have never met Phil in person, but we have had many very pleasant

Laptops may be difficult to ground because of plastic cases, but perhaps
a screw somewhere in the enclosure can provide a grounding point. The
key is not necessarily 'grounding', but instead bonding all components
to ground a laptop you can use the the Kensington lock's hole to get direct
contact to the NB metallic frame.

A problem like that could be either RF board U1 or the Control Board U6.
OR, it could be that the prior owner turned the VFO knob in an attempt
to move from one band to another (that does not work on the K2 although
the VFO display might indicate otherwise).

Be careful what you ask for. Solar arrays are not rated for average.
Probably because there is no such thing as an average sun. I'd like to say
they are rated for peak power but that is somewhat illusionary too. How much
power you actually get from an array depends on many things. You will
