THANKS to each of the kind folks who let me know that KX3 power can go to 10
watts for tuning using CW or FM.
Evidently I had misunderstood some earlier list content about PSK being
limited to 5 watts.
I appreciate the feedback!

I had the SGC 100 watt unit for many years feeding a classic 130'
doublet.
Upgraded to the 500 watt model 3 years ago.
Both of them take around 6 seconds to find sweet spot with this antenna
with 15 watts applied from the K2/qrp.
160m to 10m
The LDG Z-11, Z-11Pro, and RT-11 have all tuned successfully over the
years with the output of my 3-watt Sierra and my 2-4 watt KX1, let alone
my Herculean KX3. I'm not sure where the LDG folks are coming from in
their comment about needing a higher power for their units to tune.
That's one
I also think a tuner designed to be placed at the antenna feed
point is a good idea. Power over the coax to the station would
eliminate the need to lower the antenna to change batteries. For
a real Elecraft tuner, it would communicate over the coax with a
box in the station which would talk to
While an Elecraft product would have appeal, the SGC230 fits that bill
without batteries and has a long history of reliable operation in very
severe environments such as on board ships where it's enveloped in corrosive
stack gasses and doused with sea water regularly, baked under tropical suns
and
The SGC 230 is well regarded but has serious power limitations. It is rated at
200 W PEP and only 80 W continuous (RTTY). The K3 alone can exceed these power
limits on RTTY. And furthermore it is inadequate for use with the KPA500.
The MFJ-998RT claims to handle the power but the reviews on
I have the MFJ-998RT and use it everyday with an Alpha (and my K3). When I
first got the tuner I tested it in the shack with 20 second key downs at 1.5KW
into the dummy load. I had the cover off so I could feel how warm it was
getting - no issues at all. It's been a very good tuner for me. It's
The LDG tech support folks say that a 5-watt KX3 output is not enough to
trigger tuning by their product.
We will eventually have the Elecraft tuner for KX3 when it ships, but for
now what selection of modes power etc on KX3 would give me the
highest-wattage signal for the autotuner? If I
Just switched to the KX3 internal ATU, but I had been using 5W to tune a
Z-11Pro with no problems.

Dave,
I have a tuner in my K2 (built in 2005 KAT-2) and one in my KX3. they
never failed and in most if not all cases I was able to tune various
pieces of wire tossed in trees to dipoles, resonant or not.
These tuners are very unlike the YaeComWood-tuners you mentioned and
do tune vast ranges
Julie,
The KX3 power in CW and data modes is *not* limited to 5 watts (except
when running it on internal batteries).
I believe the solution to your problem can be found in the TUN PWR menu
parameter - see page 40 of the manual. The power level set there will
be transmitted when you do a
I was wondering if you have an Auto Tuner planned now that you have the
KPQ500?
I have found my OCF dipole has a higher than I would like swr on 20m
etc., and my G5rv is also higher than I would like, I don't want to hurt
my new gear.
If you do not have an auto tuner in mind, how would I connect

LDG is shipping a new 600 watt auto tuner this month for only 359.00. It
supports Icom and Yaesu for tracking with a cable. Emailed the factory
about the K3 and they said they had no plans to support Elecraft. That
tuner with the new amplifier would be perfect and LDG is missing the boat on
I'd just let them miss the boat. Based on some comments by Eric at Ham-Com, it
is probably not unreasonable to believe an auto-tuner for the KPA500 power
class will be covered in a P3 sized footprint. Probably after the KPA500 ships
later this year.

For what it's worth the Band Decoding in the K3 is compatible with Yaesu
band decoders. If LDG is compatible with the band decoder of Yaesu then an
appropriate cable from the tuner to the DB15 connector on the K3 should
work. Such a cable is available from Array Solutions.

I think you have probably just listed the reason LDG isn't supporting
Elecraft - they can't handle it.

Ron group,

version without latching relays) with my (then) basic cw K2it worked pretty

little better and is much handier (no jumper
Sorry, I failed to notice that your inquiry was about using a Z-11 with a
K1.but I think my commects about using the LDG with a K2 will still apply
to the K1.

Has anyone used the Z-11 with their K1?
I'm finially getting off my tail and ordering stuff to upgrade my K2 to a B
version and adding the 160m, and Noise Blanketer options before anything
else happens. lol. I'd like comments on how well the auto tuner works, what
you think of it, bla bla. I've got the T-1 which I just love, think it
Jerry:
The K2 autotuner seems to work FB for me. I don't think you can go
wrong getting one. It's a lot more convenient than having a separate
tuner. Just push the tune button and away you go. And it seems to
tune just about anything.

In defense of the KAT100 Tunerwhich I do not believe was being
attackedbut, in its defense.
I have come back to the fact that the LC or CL antenna tuner is a very good
tuner concept. See recent articles in QST. The LC tuner is quite the tuner
once you understand what it is doing
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.

operating and when I am ready all of the assemblies of the
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
John W2XS, I have been wondering about a balanced L
network auto tuner for some time now. No one is
making one that I know of at this time. Like you, I

produce a kit for it.
And Don K7FJ, I would be very interested in following

There is acompany out of Germany that has made such a device for

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*
