Gerald,

Repair implies a failure has occurred.  Most radios these days, and  
certainly Elecraft, are highly reliable rigs short of receiving some sort  
of abuse.  Sure, failures do sometime occur, but fairly rare.  There are  
countless thousands of Elecraft and other radios on the air after years of  
use with no problems.  Many being carried to mountain tops (SOTA) and back  
frequently.  I bought a TenTec Triton IV in 1978 (?) when they first came  
out - the first solid state full CW QSK rig ... and quite a few rigs  
since.  Haven't had one failure on any of them in those 40 years.  I don't  
think you have much to worry about.

[Elecraft] Field repairs to K3s

[Gerald Capodieci]

Where do I look to see how to troubleshoot a K3s at the shack and just
order the new parts.

I'm looking to buy a radio that does not need to be sent back to the
manufacturer for basic repairs. I'd also like to buy a radio from a USA or
North American company for support.

Actually, you said below, "I evaluate IMD blah blah..."


FWIW, I really don't care about IMD as a number. What I'm concerned with is 
clicks, splatter, and phase noise from another station that's loud covering a 
weaker station I want to work.


Since the numbers are more-or-less specified by Elecraft I'll go by them.  I say 
more-or-less because they don't actually have a firm specs.


While it might be "well known" that IMD decreases at lower power, it isn't 
necessarily true. 


Right -- it depends on the transmitter design and implementation. K6XX's work 
shows that to be true of the K3, and my measurements (done on 20M as I recall) 
confirmed it.  I also recall that you noted increased IMD around 15W, which is 
likely the result of the K3 firmware causing the power amp to be turned off 
and the QRP output stage to be driving the load at it's full rated power. 
Under that condition it is consistent with my (and K6XX's) observations that 
IMD is often lower at reduced power output.


You recall incorrectly.  First, I've never stated that and second, the HPA 
engages at 12 W.  I have however, stated in strong terms several times in this 
and other forums that a K3 should never be operated above 10W on the LPA.  I and 
others have asked for a firmware change that would insure this.


What is really not well known is that in the K3(S) IMD is highly frequency 
sensitive. 


That's news to me.


Well even experts can learn something new now and again.


The 3rd order IMD in my K3S at 10W output varies 18 dB with respect to 
frequency.


Again, the power amp is not engaged and you're running on the driver. But that 
much variation also implies a problem. Have you sent the rig back to Elecraft?


Just four times.  (Actually, three times and I changed the HPA once.)


Furthermore, my K3S on 10, 17, 20, 30 and 40-meters has higher IMD at 20W 
than at 100W.


Interesting.


Yep.  Which is why I state that I can't with reasonable confidence measure 
KPA500 IMD.

[Elecraft] Ham radio as a side dish

[Wayne Burdick]

Many of us combine our affinity for radio with other activities we’re equally 
passionate about — perhaps more. An obvious example (one that renders this post 
marginally non-OT) is hiking / camping; for some of us, it’s a natural 
environment for small radios and big ambitions. 

What are your ham-activated avocations? Do they come with as-yet-unsolved 
problems in the field of radio ergonomics? 

Where is the boundary between communications media and the things you most 
enjoy talking about?

[Elecraft] No Tune Power Output While Split in Data Mode

[Bill Mader]

This didn't seem logical or possible to me.  So I tried it and discovered
the problem occurred on 6m, but not on 80m with my K3 and firmware 5.64.
Interesting.  This K3 (S/N 08343) has a recent EE INIT and re-load of
firmware and configuration after experiencing a power overshoot issue (now
solved).

[Elecraft] K2 Build: Options Advice

[Dauer, Edward]

I see no disadvantage.  

I have built three, each of which has all of options you are considering.  As 
David says there are some parts that need to be unsoldered, and a couple where 
the through-holes need to be cleaned up for inserting something else.  
Nonetheless, when I built mine even though I ordered the options at the same 
time as the base kit, I finished the base kit completely first, then went back 
in to add the options.  Two reasons -- first, if there were to be a problem 
somewhere I wanted to be able to analyze it in the least complicated way.  So, 
K2 first, test, then each option and its test.  Second -- it's a kit.  That's 
part of the fun.

The disadvantage is that you will need to unsolder some components.  In 
most cases, I think you can destroy the through holes, but there is at 
least one case where you have to insert a new value in the old hole.

There used to be a, third party, product, called UnPCBs, which provide a 
minimal dummy version of most of the modules, but the sales of the K2 
dropped to a level where it wasn't worth another production run for the 
PCBs for this.

Re: [Elecraft] Too Much Power

[Jack Brindle]

I’ve seen Bill’s setup. 50 watts with a decent gain antenna (i.e. beam) is 
equivalent to 800 watts with Bill’s antenna and QTH. He really has done an 
outstanding job with the resources he has to work with.
Also remember, we are talking about a 4 to 5 db difference in power here. And 
when you have pretty large mountains blocking your path to JA and EU, that 4db 
of power can make a huge difference.
QTH and the antenna system really make a huge difference!

[Elecraft] Too Much Power

[Richard]

“I have a couple of FT8 contacts in my log -- with a DU and a JA -- reporting

Why do you think you need 800 watts in a weak signal mode? Do you have any idea 
what that does to other operators? I’ve made several 10,000+ mile contacts with 
50 watts, as have others who are following the “rules.”

Re: [Elecraft] Does KPA1500 have these KPA500 characteristics?

[Bill Frantz]

In casual conversation, I had an Elecraft developer suggest that 
to minimize IMD, you don't want to drive an amplifier with the 
K3 output power near the top of the QRP amp range (just below 12 
or 13 watts). I generally stay below 10 watts, but would like to 
have the 100W amplifier automatically engaged if that will 
reduce IMD.


Note: I am sometimes driving my Expert 1.3K amp to 100 watts 
output on FT8 just to save the batteries powering my K3. It also 
makes it easy to QRO, and I have a couple of FT8 contacts in my 
log -- with a DU and a JA -- reporting me at -24 dB where I was 
operating at 800 watts. YMMV.

That's to be expected of any class AB power amplifier.  The dissipation may 
actually be lowest when it is driven into saturation, not recommended for any 
mode except CW.  And even on CW, it could generate key clicks.

Re: [Elecraft] PX3 Screen Issue [clarification on repair/replacement]

[Wayne Burdick]

John_N1JM, wrote:

Hi John,

Reliability of the PX3 front panel circuit board and LCD is extremely high 
(ditto with the P3). We do get an occasional request for LCD replacement, 
usually after the PX3 has been operated portable and sustained damage in 
transport. 

The bezel (~$21 replacement cost) usually takes the brunt of the damage. If a 
new LCD is required, it's ~$100. Replacement instructions can be found in the 
PX3 Owners Manual. 

I don’t think we’ve ever had to replace an entire PX3 front panel module. We 
could repair it in virtually any scenario short of grizzly attack.

Re: [Elecraft] K3 - USB

[N2TK, Tony]

Hi Fred,
That is exactly what happens when I plug in or remove the USB cable. Narrowed 
down the problem to the KIO3B Main Board. Ordered a replacement board.

Watch Control Panel --> Device Mangler --> Ports while you plug in the USB 
cable to the PC.  You should see a new COM port come up.  That's the port you 
use to talk to the radio.  It's faintly possible you are missing or have an old 
driver, but Windows almost always installs the correct driver transparently 
when you plug in the cable.  Unplugging the cable will cause that port to 
disappear.

Swapped the KIO3B Digital I/O board between the two rigs. I can't transfer
the problem.

The only thing plugged into both rigs is the Powerpole and USB cable.

I am using the same USB cable to go between both rigs.

In Win 10 >Device Manager > Universal serial bus controller, I see added
"Generic USB Hub" when I plug in the USB cable.

  


What could I be missing or check?

Tnx for any feedback

[Elecraft] Tuneup, Rescue, Build your K2 and others

[Alan D. Wilcox]

Hello,

Does your K2 need repair? Tuneup?
Want to sell it, but it needs some attention before offering it for sale? 

In addition to tuning your rig, I can also rescue a building project you might 
have started some time ago.

See what my clients have said about my construction and service work at 
http://www.eham.net/reviews/detail/6768 

Photos of the popular "Twins" -- the KPA100 and KAT100 in EC2 enclosure --  are

Re: [Elecraft] K2 - Issue after installing K60XV

[Neil Zampella]

Well .. I checked the D19 setting, and it was set to 'Y',  did the 40/80 
alignment went OK, then to verify, did the complete VCO voltage checks 
as listed in the K2 manual on p64.   All were fine.


So far so good.  Continued on with the 40/60 alignment tuning as listed 
in the K60XV instructions, and could not get the power showing under 
TUNE higher than 0.1.


OK .. figured lets bypass the K60XV, so I unplugged the board, found the 
4.7 pF capacitor and inserted in pins 1 & 3 of J15, added a jumper 
between pins 3 & 5 on J13.   Left D19 as set per the K60XV 
troubleshooting instructions on page 60.   Then tried to check the 40 
meter power.


Same results.   So I put everything back together.  Removed the 
capacitor & jumpter, reinstalled the K60XV,  put the KPA100 back on, and 
went back to the shack.


Figured I had better hook everything up (K2 & KAT100) and make sure the 
other bands can tune.   Powered it up, and it was sitting on 40m.  Said 
what the heck, and pushed TUNE .. 2.0 watts showed up on the LCD display 
... THUD.


Could it have been as simple as not properly aligning the pins of P1 and 
J13 ???    Even P2 and J15??   The board was recognized when I initially 
installed it,  so I'm at a loss, but happy to see 40 & 60 working.


Thanks for all the advice.

Neil Z, KN3ILZ

Neil,

Did you set the secondary menu D19 parameter to "Y"?

If you have the KAT2 installed, be certain the change KAT2 R6 to 470 
ohms, there is a resistor provided in the K60XV kit for that.

Hi all ..

has anyone seen this type of issue with their K2.   Before installing 
the K60XV, I had no problems seeing 10 w on 40 meters.   After 
installing the K60XV, I can't get above 1 watt on 40 meters OR 60 
meters.


Did I screw something up, or is there some menu setting I missed when 
I did the installation?

That's to be expected of any class AB power amplifier.  The dissipation 
may actually be lowest when it is driven into saturation, not 
recommended for any mode except CW.  And even on CW, it could generate 
key clicks.

[Elecraft] KX3 in International carry-on luggage?

[j...@kk9a.com]

There are airline regulations regarding batteries so you should check to
make sure that your battery sizes are acceptable.  Bringing a transceiver
though security is usually a piece of cake. I have TSA Precheck which I
think makes things easier in US airports but I rarely have had to take my
K3S out of my carry-on luggage anywhere.

Re: [Elecraft] KX3 in International carry-on luggage?

[Carl Jón Denbow]

I don’t think the battery would be a problem with carry on.  I’ve traveled with 
all sorts of iPhone backup batteries, with a larger capacity and physically 
bigger than the KX2 or KX3 batteries, and never had a problem.

[Elecraft] Does KPA1500 have these KPA500 characteristics?

[ANDY DURBIN]

"The KPA500 actually runs cooler at just-below-fault power output than it does 
at either 500 or even 400 watts output."


I ran a quick test to see if I saw the similar results with my KPA500. The 
quality of the data is limited by the low resolution of power returned by the 
^WS command but it shows that PA heating is 350 +/- 25 W for all output power 
levels between 150 W and 500 W. Below 150 W the PA heating falls off with power 
output. The cluster of points close to 500 W lies at about 330 W heating which 
does support the idea that PA heating will be less at max power output. I did 
not extend the test beyond 500 W output.


I may try the test again with a better controlled drive ramp rate but the 
quality will still be limited by the resolution of power returned by ^WS. To 
get better results I'll need to expand my logger capabilities to include 
sampling of my LP-100A power data.


73,

Andy, k3wyc

[Elecraft] KX3 in International carry-on luggage?

[John Perlick]

I have traveled to Europe/Caribbean a few times with my KX3.  I just packed it 
in my (carry-on) suitcase or in my backpack and never had a problem. I didn't 
pack it with batteries, because I could always just plug in a universal 
adapter.  You might choose not to bring batteries if you can get a good AC 
power adapter--just bring the appropriate plug adapters.

Also, I learned the hard way, the antenna is more important than the  radio!  I 
used an end-fedz which worked great only after I strung it out away from the 
hotel building--all the steel in the building just ruined the signal.  Get it 
high and as far away from other structures as possible.  Let the internal

Re: [Elecraft] KX3 in International carry-on luggage?

[Mike Markowski]

Somewhat along those lines, at work our Keysight tech rep (formerly 
Agilent, formerly HP) was driving to a customer location and had a 
backseat full of electronic lab measurement equipment.  He said the LO 
in something set off a police radar-detector detector, and radar 
detectors are illegal in the state he was in.  After being pulled over 
he was certain the cop would see a back seat full of cables, high tech 
gadgets, and think he was up to no good.  He told the cop he didn't have 
a radar detector and they could go through the equipment to find the one 
that set off his detector.  The cop looked at all the gear and just said 
to keep driving.  :-)

Re: [Elecraft] KX3 in International carry-on luggage?

[allen Montoye]

I took my Kx2 on 6 flights this year. Two international. Only twice did a tsa 
official even open the waterproof box it was in.  And that was a newbie who 
just stared at it for a while until her supervisor took a quick look at it and 
said “okay” it was fine to carry on.  The airlines publish on their websites 
the specs on the size of lithium batteries that can be carried on. The specs 
are given in Watts. The 2600 ma elecraft  batteries are well below that.

Re: [Elecraft] KX3 in International carry-on luggage?

[Ka7phr]

I just carried mine as well as the px3 all the way to India and back in carry 
on with no issues.

It's a pain in the ass to have to unpack and repack my carry on every time I 
went through security but they were more concerned with liquids than any of my 
electronics.
Which were
Kx3
Px3
Yaesu ft2
Icom 51
Goal zero Sherpa 100
iPad
Microsoft surface
Dell thing
Garmin rhino
Electric shaver

Subject: [Elecraft] KX3 in International carry-on luggage?

Waiting for my KX3 to arrive.  I will be doing some international travel in
the summer.  Just wondering if anyone has carried the KX3 in carry on
luggage or a backpack.  Do security officials get upset with the battery?

Re: [Elecraft] K3 - USB

[Don Wilhelm]

Tony,

The computer must also enumerate a COM port that is associated with the 
adapter in the K3(S).


If it goes not, go to the FTDI website and download the drivers.

Swapped the KIO3B Digital I/O board between the two rigs. I can't transfer
the problem.

The only thing plugged into both rigs is the Powerpole and USB cable.

I am using the same USB cable to go between both rigs.

In Win 10 >Device Manager > Universal serial bus controller, I see added
"Generic USB Hub" when I plug in the USB cable.

  


What could I be missing or check?

Tnx for any feedback

N2TK, Tony

[Elecraft] KPA1500 Remote Program

[N2TK, Tony]

Any word on the KPA1500 Remote Program? Once the program is available I can
move the KPA1500 alongside my KPA500 on a shelf in the basement.

73,

N2TK, Tony

[Elecraft] Fwd: KPA1500 Order from 10/16

[Tom Schaefer]

I received a call from Elecraft today confirming my address and the amp would 
be shipped out today. Tracking info says that UPS picked it up and it is 
supposed to be here in Florida on June 1st. This was ordered on October 16th, 
2017.

I’m just guessing but I suspect this pleasant surprise is a combination of 
ramped-up production plus somewhat of an order lull after the orders of the 
first week were placed in August.

Regards,

Tom NY4I
