K3 strange power surging behavior

NZ0T
My K3 SN 1502 with MCU 4.83 is exhibiting a strange surge in transmit power level.   When the rig is keyed in CW with the power set all the way up power output surges from a high of around 140 (!) watts down to 60 watts and back in a rapid fashion.  It is at it's worst on 30 meters shows at least a high power spike on all bands except 160 and 80 before it settles down to around 100 watts.  If I turn the power down the cycling is much less severe but there is still a leading spike of around 140 watts.  I have tried reloading the firmware with no luck.  I have checked all my jumpers and connections and they are fine and the rig does this even straight into a dummy load.  My power supply is an Astron RS-35M in great shape.

I should mention that we suffered a lightning strike last Labor Day weekend that took out my Ten Tec tuner, W2 wattmeter and a few other things but the K3 was not affected at all and I hope this problem is not some delayed thing from that strike!

An ideas?  The rig is almost six years old - maybe I need to open it up and make sure screws are all tight?

Bill,

I cannot assure you that this is not some delayed effect of the
lightning strike,
However, try doing the TX Gain Calibration before anything else. You may
want to run it 2 or 3 times if it does not help initially.

If that does not correct it, you will have to contact support for
further assistance.

Re: K3 strange power surging behavior

Raymond Bass
I've been thinking about getting the K3, P3 and the amp but with all these problems I keep seeing I hesitate to purchase. I talked to a few owner that love the k3 so perhaps this is only a small group that has problems or do a lot of owners have these problems? I ned to know more before I shell out a lot of hard to dollars.  Any suggestion fellows?

Re: K3 strange power surging behavior

David Bunte
Ray -

One of the great things about this list is that when a person does have a
problem with an Elecraft product, there are a large number of users willing
to help resolve such issues.  Also, please remember, that for "most" of us,
if our rig is working as we want it to, we are not likely to say anything.

I believe that problems which may show up here, represent a small
percentage of users... and, in many cases it appears to me that the problem
is not with the rig itself, but perhaps a faulty cable, or a parameter that
needs to be adjusted.

I am by no means an expert, but I have had my K3 for a little over three
years now with NO problems at all, and I know a number of other folks whose
experience is more like mine, than like those with problems.  I do have one
friend with a K3 that frustrated him at first because it worked one day,
and not the next.  It turned out that there was NOTHING at all that was
wrong with the rig, but as he was getting used to it, he often pushed
buttons without paying attention to what he was doing, and without
following the manual.  He is 92 years old, and does sometimes get in a
hurry.  In each such case, I was able to put the parameters back where they
needed to be, or tell him on the phone how to do that.  It has now been
several months since he experienced any such problems, and the rig performs
perfectly.

I think if you "pull the trigger" on the K-Line you will be very well
served.  My K3, P3 and KPA500 are, by far, the best I have owned in 57
years.  I know there are a number of fine radios out there.  I was able to
borrow a K3 from a friend, and that clinched it for me.  I have not wished
for anything else since I put the K3 on the air.

I don't weigh in on this list very often, because I am usually just working
DX and chewing the rag with great satisfaction.

What ever you decide, I wish you the best.

Re: K3 strange power surging behavior

Scott Manthe-2
In reply to this post by Raymond Bass
There are more than 8,000 K3s out there. What percentage do you think
are exhibiting problems? The great thing about owning a K3 is this
forum. If you have a problem, there is a community of owners, including
numerous representatives from the company that makes the rig, there to
help you. I'm still looking for the Yaesu or Icom forum in which company
representatives are there to help you and solicit recommendations for
new features. If you've heard of such a forum, let me know.

There is a reason that significant numbers of world class contesters and
DXers own K3s, and I assure you it's not because of reliability issues.
My suggestion would be for you to understand that in a forum like this,
people talk about issues they are having. That's kind of the point. The
difference in owning a K3 or something else is that, because of this
forum, if you have an issue, you might very well find yourself asking
the person who designed your rig if there's a way to fix it. I can't
think of a better reason to spend your hard earned dollars with Elecraft.

Scott, N9AA

Not only that, but the two OWNERS of the company read this list every
day, and chime in with advice when needed. I've seen one of them, N6KR,
who's the principal design engineer, work one on one with DX trips to
solve issues, and I've had more than a few one on one engineering
conversations with him at hamfests and online. Heck -- we can't even
correspond with low level flunkies at the JA companies (or Ten Tec), let
alone the guys who own the place! And both owners are active hams, I've
worked both of them on the air.

How about this for support?  There will be a bunch of K3s in the
international WRTC competition in New England next weekend, and Elecraft
is sending at least one of their best engineers (who was a competitor at
WRTC in Russia 4 years ago) to support those radios. I know because he's
my neighbor, K6XX.

I've been an Elecraft owner since 2004, and bought two K3s in 2008. I'm
very pleased with their support. EVERY radio has issues -- with
Elecraft, there are much fewer of them, and you can get them fixed!

How many K3s are there in a 'bunch', Jim?  The implication would appear
to suggest that there are likely to be problems requiring a best
Elecraft engineer to fix them.

And then there's the factory support.  I've worked for small specialist
UK based broadcast electronics company and also was a project manager
for a large Japanese company. At both companies we were dealing direct
with the end user.  The support from the factory is second to none.  
Many UK retailers could look to Elecraft to see how to do it...

Hi Ray
I could conclude that in USA are killing universities judging by the
news I see on TV, but reality is different, there are hundreds of
millions of people living normal healthy lives and peace. This mailing
list accumulates questions and issues, then probably you inbox will be
flooded of questions and issues of less than 0.1% of happy users of
great K3.

I'm another user with K3/P3 working perfectly since 2010 !

Re: K3 strange power surging behavior

NZ0T
I should add that after my OP I got the ERROR TXG which indicates a problem with bandpass filters.  I have emailed support about this.  I will try the TX calibration tonight after work.

For the poster expressing concern about the reliability of the K3 - I built my K3 in August 2008 and it has seen heavy use since.  This is the first significant problem I have had in nearly six years.

Ray,

Count the number of problems you see posted here (or in the archives) in
a month or even a year.  Try not to count those that are requests for
"how do I do ..." assistance.  I think you should also discount the "my
shack was hit with a lightning surge" reports as well, but that is up to
you.

Then consider how many K3s are out there - over 8000 K3s, about 4000
KX3s, I don't know how many P3s and KPA500s and KAT500s.

I think you will find the percentage of actual failures is quite a small
percentage.

For many Elecraft owners, this reflector is the first resource when
'something strange' is encountered.  There are a large number of owners
who are willing to assist others with their 'problems'.
The second resource is Elecraft support, where quick responsiveness is
the norm - many have mentioned the high level of support available from
Elecraft.

In reply to this post by Don Wilhelm-4
Hi,
 I think when reading about "all" the problems, you need to keep in mind that the vast majority of Elecraft owners do NOT experience problems.  Those of us that are not having a problem do not get on the list to mention we are not having problems.

If memory servers me correctly, this "problem" was caused by a nearby lightning strike, so no matter what equipment a person might be running, there would be problems!

I own a couple of K3's, P3, KAT500 tuner, KPA500 amp and am extremely pleased in their performance, using them on an almost daily basis.

I have no vested interest in Elecraft, but truly believe there is no better product on the market.

There are nearly 8,000 K3's out there. And yes, issues come up. But they are not systemic. The K3 is a very flexible radio and can be configured to work to suit the owner/operator. I believe you will be very pleased with it if you choose to buy one.

All current HF rigs work quite well and each has it's strengths and weaknesses. But I feel the K3 shines above the others in many ways.

First it is modular. The basic radio is really quite nice and you can do most HF operations with only the basic 10 or 100 watts plus the ATU. This combo is priced near the high end of basic level radios but is a lot of performance for the money. Many users stop here and never need more.

But you can add just about any feature others have as you need/want them.  You can add everything and still be under the price of some of the other brands deluxe offerings.

And your radio need never be out of date. The very first K3 can be updated to the latest firmware/hardware at any time (usually by the owner). And as features are added or bugs arise, they are quick to make updates available and easy to install.

And the company support is second to none.

And there is this reflector with many users who have been "there" before. It's almost impossible to ask a question that someone hasn't asked before or a problem that hasn't already been solved.

A K3 isn't just a radio, it's an "experience".

I have the full "monte" and love it!

I have to agree. Remember, we generally only hear about the failures -
not the multitude of successes.

For the most part the questions asked on the reflector are good and the
replies could be of value to the reflector users if:

1. the replies are on topic
2. the replies are not too lengthy (containing too much theory)
3. the replies are made on the reflector and not sent via email
4. the replies are not made in a hateful manner

My friend and I had similar power surge issue with our brand new K3. Having thoroughly made trouble shooting, we found the cause mostly coming from outside K3 or some glitch on constructing K3. I would recommend to carefully check your entire system including coaxial cable to your antenna system as well as inside K3 especially KPA3 to antenna connector.

Last time around, four years ago in Russia, something like 60% of the
radios were K3s.

Geez -- some guys will read something negative into the most positive of
comments.

That's the implication because we as a society have an amazing ability
to spin something like this in the worst possible way.

I can think of a few dozen other reasons that aren't as dire.

It's one of the reasons that most amateur radio companies don't have a
forum like this, and the owners and employees don't speak publicly.  If
you don't say something, no one can take it and spin it out of control.

I don't know how many K3s will be there. At one time it represented something like 50% of the total. At 9 pounds, it's pretty easy to take a K3 anywhere.

K6XX is going because he's one of the world's top DXers. He just happens to work for Elecraft.

And Bob is officially representing us there to answer questions from both the
WRTC K3 users and potential K3 buyers. We want the other 50% to be future K3
owners too! :-)

Re: K3 strange power surging behavior FIXED!

NZ0T
I had an email from support at about 9:30 Central.  Asked me to tighten the screws on the bottom panel that go to the LPA.    Then perform the TX gain calibration.  The rig worked perfectly after I tightened the screws but did the calibration to be safe and passed with flying colors.

Great service and support as always!
