I spent almost 2 hours looking for the missing pieces, without
success. There are several alternatives I can think of to use as
temporary spacers. Fortunately this has been the only mishap during
assembly, and hopefully the last.

You need only some kind of spacers that are the thickness of 2 PC boards

for WSJT (AFSK A) it is the "zero beat" frequency, i.e. the same as in USB.

Thanks for the comments on using the KX1 on the trail. I will probably wait on
something like the AlexLoop but I am curious about how it performs versus the
Buddipole antenna. I mean, if I am going to carry an antenna contraption
rather then just coils of wire, the Buddipole looks interesting
Tom, thats true if you have one radial, but making it 1/4 wavelength long
minimizes RF on the rig and, in most situations, only a small part of the RF
flows in it. Its a function of the ratio of the impedances of the "radial"
and the radiator.
Consider the "ideal" case. A radiator close to 1/2
Any wire works with about 1/8 wave the minimum.
Usually BL2 is not needed. For antennas with high SWR BL2 heats and seems to
absorb nearly all the power.
I used my K2/10 in ARRL contest from a park in Galveston Island, TX. About
25ft wire to a palm tree and one radial. 5 continents in 30 min. Th
Ditto. I've used my AlexLoop (standard version) with a KX1, and been
amazed at how will it works. My first QSO with the AlexLoop and the
KX1 was with a station in Maine (from here in EPA). I was running
about 1 watt. I forget the report, but we had solid copy both ways.

Check out the AlexLoop WalkHam portable magnetic loop antenna at
www.alexloop.com. I have used this on local hikes with my K1 and KX1 and it
works great! You'll need a cheapo photo tripod. It is bulkier than a simple
wire but still lightweight and comes with a handy carry bag as well.

Just to restate the obvious: Do not make the radials resonant on any of the
operating frequencies. Doing so causes high current in the radials and you
end up with a *very low *horizontally polarized radiator.

The displayed frequency in DATA modes depends on the DATA sub-mode.
Assuming you are using the DATA A sub-mode for WSJT, the displayed
frequency will be the suppressed carrier frequency, the same as it would
be if you were using USB mode.

John, as a general rule I try to get at least 1/4 wavelength of radiator up.
That's not always practical but it's worth striving for since below 1/4
wavelength the feed point impedance and so the efficiency drops very
quickly.
If you are working against a counterpoise, something close to 1/2 wave
A good starting point is to make length of radiating wire and length of
counterpoise odd multiples of a quarter wavelength at frequency of interest.
This puts relatively low voltage at feed point with resulting relatively low
impedance and easy matching.

This summer I plan to take my KX1 in my backpack on some of our summer hikes in

Nidge,
From your description, you have the older KPA100 - the changes are in
the T/R switch area, and the reason for the change was to cure potential
oscillation.
Take a look at the instructions for the KPA100SHLDKT to see how the two
solder lugs connect the SO-239 directly to the shield.

I've just removed the KPA100 from the base and removed
the cover.
RFC1 appears to be a largish black choke (not torroid) with "101" printed on

L15 and L16 are Red Torriods, therefore it would appear that

Nidge,
First help me establish the level of your KPA100.
Do you have blue toroids at RFC1 and L16? If so, look at the value of
C31 - it should be 0.22 uF. If C31 is 0.033 uF (33nF) it must be changed.
If you have red toroids at L15 and L16, then your first step is to
install KPA100UPKT.

Yes, that is the symptom of damaged diodes D16 and D17. There is also
