It's my K2, not my K3, that's in trouble. Mercifully, my K3 is playing very

Could I have somehow fried D16 D17 in the KPA100? I checked these diodes
in-circuit with my multimeter diode test function and there is no voltage
drop across either. Does this mean they've both failed open?
No voltage drop across a diode should mean it failed shorted. However,

Yes, that is the symptom of damaged diodes D16 and D17. There is also
the possibility that U5 and or U6 is not responding properly, but if you
measure no voltage drop across those diodes, they are for certain
toasted. Start with the diodes, and after that we can move on to the
other
I have to disagree on that one. 15 and 10m bands are hugely underutilized
these days even when there are decent openings. I will take what I get but
would certainly welcome higher sunspot activity with the better openings on
the higher bands. So far the current cycle is a dud. There was some
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.
Sale pending ...

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

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.

Hank, W6SX
On Fri, Jun 17, 2011 at
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
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.

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

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.

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.

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.
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
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
Hi Roger,
for WSJT (AFSK A) it is the zero beat frequency, i.e. the same as in USB.
Concerning frequency display you can adjust that in the menu, see under set
transverter offset in the manual.
