Guys and Gals of the K3 ilk,
I am interested in setting up my K3 to run off of solar power but know
very little about what it will take. I assume a battery and a
controller/charger but what size battery would work best for operation
up to 10 watts, and what would work best up to 100 watts

Oh go ahead and get the flooded cells. The weight is spread over six
individual cells and the weight is under a hundred pounds per cell. That
way you can have quite a few cloudy days without concern. I have six

Thanks to both of you for the sugestions. I actually got this to work, and
I am not sure if it originally worked, or if my resoldering fixed a
problem. I was able to obtain a voltage reading but only over about 20
degrees of the rotation of C55. I had no idea it would be this touchy.
Also,
I have used my K2 and later K2-100 as my camping rig since the year 2000.
This year I wanted to try my K3-100 for field day as QRP 1B ND. I took the
K3 with me over Memorial day and ran it at 100 W CW. On Sunday morning
I did 160 meter SSB and AM. I was pleasantly surprised how well the battery
Alan W1HYV built this little gem for me and he did a beautiful job. This was a
very old kit s/n 192 but it had the rev B RF board so it ended up with the
newer serial number. Alan also installed a few mods which have occured over
the years since this old kit was bought. With the help of the
Thanks to all for the feedback, comparing these two VHF solutions.
Unfortunately, it's still not an obvious decision. I'm inclined to go
with the XV-50, because I need another kit to build ...

Nice, has anyone tried running the K3 (or other rig) directly from the
DC outlet of a Honda generator?

On my EU2000i, this is an unregulated output and the maximum voltage
output is higher than the K3 is rated for. Not recommended.

This is supposed to be a battery charging source. I wouldn't even subject my
batteries to this
I have a East Penn Deka 92 AH AGM battery in the shack that is on constant
charge via a smart charger that I built using an Astron RM-35 for the raw DC

What did you use for an antenna when you were camping in Northern Mn?
This is a Honda eu2000i question mostly. They can make a lot of noise
especially into low mounted verticals.

I used a Honda on field day a few years ago, (240V mains outlet) and was
staggered by the amount of SMPS noise. I fitted a big filter grounded local
to the generator about 60ft away that made it tolerable.

Today I have put it off and on 6/7 times and it still remains. Checked all

Curt,
Go ahead and install C78 and RFC8. They are necessary for 80 meters,
but will do no harm to the other bands or any of your calibrations.

Tom,
Yes, the balance point is very 'touchy' - such is the situation anytime
you are trying to get a null (on any kind of equipment - the null range
is very small, and ideally is a single point). On the KAT2, the normal
lowest reading on the display is in the 009 to 011 range as you have
Curt,
Switching filter boards on the K1 is quick, but enough of a pain that
I find I don't do it often. Unscrew the top cover, unscrew the tuner
(if you have it, which you should, I think), lift out the tuner, lift
out the filter board, plug in the new board, screw in the tuner, screw

K3 #1605
After purchasing a KAT2 kit together with my K2 kit in 2008, I never built
the KAT2. After using K2 s/n 6424 for more than a year with a ZM2 tuner, am
debating whether to just sell the KAT2 kit. Not sure what if anything am
missing by not having an autotuner installed in the K2. Any advice?
You mean something like
Regedit /E myfile.reg HKEY_CURRENT_USER\Software\Elecraft\K3 Utility
Use notepad to examine myfile.reg to verify that it has what you expect
(only keys and subkeys of the K3 Utility)
Copy myfile.reg to the other machine,
and on the other machine,
Regedit myfile.reg
?
Thanks for that info Lyle, I wasn't sure.

Hello John,
Agreed. ATU is a preselector / filter in certain extend. It will improve
isolation and selectivity though not significant but noticeable.
KAT2 is not cheap when compared with other antenna tuners say from LDG or ZM2.
However, the merit of having KAT2 is that you get everything in
I see your point. :)
At the sake of being too simplistic, here is *my* point:
Yes, but more like:

Peter - The XV-50 and a K2 is not really a cost effective way of
getting on VHF. Besides the KIO2, you will also need either the K60XV
or the K160RX. And if you want SSB, you will need the KSB2. If you
already have the K2, the cost may be reasonable given the good
performance achieved, but
Bill is a good friend of mine and he has given me lots of points in
VHF/UHF contests, for which I am very grateful. I think his views on
QRP at VHF are overly harsh though. QRP does not fit into Bill's six
meter goals and operating style, and I accept that, but that does not
mean QRP is
May be I would like to add another point for the setting up of XV50+K2.
It is NOT quite necessary to get the KIO2 and KV60 transverter interface to
work K2 + XV50. XV50 is so well designed that it can work with a wide variety
of combinations. To be marketable product, the entire XV series

At one time 5 or 10 watts was pretty typical on 6, 2 and 1-1/4 meters unless
