I am experimenting with using the K2 rant input (that's receiver antenna, not
verbal outburst).
I want to use my 20-meter quad as a receiving antenna when I am transmitting on
160 with an inverted L. It is a lot quieter. The L is right next to the quad,
so a lot of voltage is induced in the
Hi Phil,
I designed the KNB2 before the KNB1, and the KNB2 is the more versatile
the two blankers. It also has more dynamic range, compatible with the
K2's receiver.
If your friend wants to use the KNB2 in his own design, he'll need to
substitute discrete control signals for those that are n
Hi Everyone,
A good friend of mine wrote the following to me, and I was hoping I might
get some comments from this list. He is working on incorporating an
Elecraft noise blanker into his old KWM-380.
I looked at the noise blankers for the Elecraft K1 and K2 and they seem to
be fine for my K
Mike,
Trouble with that is you can't predict which of the 8 capacitors will be
connected. It may be the ones from only one side of the output bus. My
original breadboard, now scrapped, used just one relay per capacitor and I
found that the circuit was badly out of balance when *no* capacitor

There is acompany out of Germany that has made such a device for
years... it's very well built, but very expensive.

I was by no means criticizing any other auto tuner with the Auto Tuner Wish
List, including Elecraft's. The reason for the wish list in the first place
was to express the desire for a BALANCED tuner - by design - not an
unbalanced tuner by design with a balun on the output. I am sure the KAT100
Funny you should ask. That is almost exactly what I want except I want mine
to handle at least 500 watts (with *my* antenna anyway) and fit in a K2
case.
I am designing and building my own. So far I have a fairly neat breadboard
operating and when I am ready all of the assemblies of the brea

I have come back to the fact that the LC or CL antenna tuner is a very good

Here is what I would like in an auto tuner.
1. Balanced Output for ladder line - two sets of inductors and one set of
capacitors (like the Rich Measures roller L design). The inductors can step
along in parallel. No control software changes are needed - just another
set of inductors and relays. T

Just assembled K1 #1945 with the K1-4 option. Like you, I had some

consistently though.
The only problem with installing them backwards is that yo

I have found what I "think" is the power connector...and also some
black and red lead wire from my junk box...

True, and thanks for the clarification.
My CW PTT for the K2 does not address a situation where the K2 is keyed by

How many folks using or contemplating SO2R are using the KY commands for

Guys, come on - the real answer? Because they are less than half the

So if anyone who has two K2s is feeling guilty about it at this point,
