I am building the KSB2, and R15 (180 ohms) is missing. Can I substitute a
220 ohm resistor for this? It is the attten signal on the Mic AF.

In an earlier post, I mentioned using a small inductor - such as some
enameled wire wound on a plastic 35-mm film can - with a number of tap
points to add inductance to the antenna. It goes in series with the "hot"
side of the KX1 output. That will usually let you adjust the electrical
length of th
I've been following the 4-band antennas for KX-1 thread. Interesting and a
real challenge for field operations. K2HYD's idea of a 51 foot antenna and
counterpoise was helpful.
Some additional thoughts- the ATU in the KX-1 is a little limited, as
compared to other larger ATUs with more combinati
Good points Ron.
I usually call those RF control radials, an RF counterpoise, as sometimes
you can use one cut for each band of concern and run it around the baseboard
of a shack.
I like to think of a radial as an outside wire, and counterpoise as an
insulated inside the shack RF control aid.

Those aren't really equivalent. Those may run on Linux, but they are

What Stuart says about radials is quite true, but there is another important
reason for a tuned radial (or other ground connection) other than to improve
the efficiency of an end-fed wire.
Consider the end-fed dipole; it's probably the most extreme example of what
I'm talking about. Fed at the en
The whole concept of radials is to improve the conductivity path for return
current to the base of the vertical antenna, when the antenna is not a
complete half wave dipole, (and therefore, balanced and a complete radiator
unto itself). You are replacing always lossy (to some degree), earth or

Good decision! Actually, you may not even need to use a relay, but just
remote a switch to your operating position with a twisted pair cable. I'm
planning on doing a similar thing with my vertical setup this summer,
although my cable run is a lot shorter than yours will be.

Thanks everyone for pointing out that Elecraft has
already taken care of controlling the T1 remotely!
Needless to say that was all it took to push me over
the edge...my order went in about a half hour ago!

Hi, Ken!
It's very easy to "remote" a T1. There already exists a 3.5mm stereo
jack on the side of the T1's case. Get a 3.5mm Stereo phone plug and
wire the normally open contacts of your relay across the "ring" and
"ground" connection on the jack (no connection to the "tip"). This will

The simplest way to test the KNB2 is to rub a screwdriver across Q21 - the
RF Preamplifier- a metal case transistor which is visible when the K2 top is
removed. That will generate the kind of noise that

Well, it's probably the Pac-12. Add 1-2 more of those sections to the

someone set up, they just use the 40m coil with a jumper with an E-Z
Hook on it to select turns for higher bands. It's a nice antenna! 73

I have one too and don't plan to give it up, BTW rather than screwing
down the nuts and hoping they'll stay, I use washers for shims and
just tighten it all down, it stays put, the paddle's a bit "rattly"
but I like it. 73 de Alex NS6Y.

I just completed my KX1 about a week ago. I don't have any suggestions for you,

Proper testing requires you order more stuff from Elecraft so UPS will
