Not Ubuntu, but its parent Debian.  Right now Debian 10 (Buster) is
quite stable and nearly boring to a fault!

Re:-

If your radio computers must be connected to the internet, as mine are for DX clusters, Club Log, firmware updates, etc., etc., then this may not be a good idea, since older systems are targets for malware. When MS stops supplying security patches, the situation will become even worse.

Victor 4X6GP 

------------------------------------------------------------------------

ALL systems are targets for malware, and crypto currency mining, be
aware of that.

As for security, well, Windows 7 is OK "Now", but after Feb' next year,
as has happened within days of Win2k and XP being cast adrift, some
"new" (previously known to hackers, but unreported to MS) vulnerability
will be leveraged against Win7.?? Win 10 (& perhaps 8.x) will be
patched, but 7, ?

Depends on what % of the web is still populated by W7 I guess, MS have
pushed out one or two updates to XP long after they otherwise cast it,
purely due to the severity of the issue, and the damage even a small %
of such population could cause.?? The recent RDP issue I think being one
of them.

So long as your border gateway device is secure, and correctly
configured (UPnP disabled) updated and so on, you could survive running
Windows 9x, so long as you never "went anywhere bad" on the 'net, and
that's the problem.

You have in practice, little control where your browser goes.? OK, you
my point it at an otherwise trustworthy site (QRZ, QSL, clublog and so
on.)? But they have adverts on there that are served up by external sites.

Worse, many are animated to catch your eye, and also respond to the
mouse cursor moving across them.? ANYTHING that moves on screen is
running code, and THAT IS where the issue is.? That code can do anything
it wants, as well as what you see it doing.? Someone will probably know
you moved (even unconsciously) your mouse pointer over their add.

Some third party tools ("Ublock Origin" etc) can block many, but not all
of such things.? But many genuine sites that rely on the ad's to provide
revenue to cover running costs, may then block your access to the site
you want.

~ ~ ~

Re your border gateway devices...?? Be prepared for some firmware
updates in the near future.? One of the popular embedded OS's used
"VxWorks" has been found to have (at least) 11 critical vulnerabilities,
and this stuff runs in billions of devices world wide, designed to be
interconnected via the web too.

See:- https://www.grc.com/sn/sn-725-notes.pdf? Then scroll down to page
9 or 10 (depending on your reader)

Note too:? New problems for exposed NAS devices, that many people are
unknowingly showing to the world!

Using the K3s utility, the macros fire off 100% reliably so it's the pod switch buttons I guess. Double triggering, not triggering, sending the wrong buttons macro. It's getting worse. Looks like the hardware is not up to the task.
I wonder if Elecraft has improved the quality of performance on this item. I have had two bad ones so far and this one is probably out of warranty. I guess it's worth sending it in for repair?

Mine is also on internal power. The interesting thing is that it is so intermittent. Probably messes up about 2% of the time.

Rig:? K3S (100W with internal ATU), s/n 11064, P3, KPA500, KAT500, into SteppIR 3-el with 30/40 loop or wire dipoles/inverted-V's.

Problem:? My K3S 100 watt internal amplifier unit (K3S/100) has become intermittent.? 

It first happened yesterday while I was running 100W on FT-8.? [I have done this hundreds of times, sometimes for lengthy periods, over the past 18 months with no problems.]
 Suddenly, my power output dropped to zero, and my received signals audio and P3 display also suddenly went quiet. ? 

After some fiddling around, I figured out that if I reduced the K3S power to 10-12 watts, both transmit and receive came on again ? leading me to conclude that it must be my 100W amp unit that had dropped out.? 

I rebooted the rig and the 100W internal amp unit kicked back on. ?So I was hoping I had just triggered a protective circuit which had reset. ? The rig worked fine at 100W for a subsequent hour-long multi-band CWOPs CWT CW session at 100W.? Then, however, a few minutes into the next CWT session hours later, the same thing happened again. ?Power output suddenly dropped from 100W to 0, and received audio and a P-3 screen filled with many medium to strong CWOPs signals simultaneously went quiet.? 

I reduced the power on the K3S down to 10W, and both transmit and receive worked again, but only at low power.
Please pass along any helpful suggestions, and thanks!

Yes I have been using Ubuntu for years. I used to have probllems with it
 Every once in awhile something would break after an update.  But since
I upgraded to version 16.04 LTS (Long Term Support version introduced in
2016) it has been stable. 

At first I just used it for email and surfing the Internet - all my
iimportant software was on a separate Windows computer.  As time goes by
there are more and ore applications available for Linux and now I even
run some sophisticated engineering software on that computer. 

The main problem I have had is that installing drivers can be a pain  I
bought a certain printer model specifically because they claimed they
had a driver for Linux  Turned out yes they had a driver but it didn't
work.  (I should have Googled it before I bought it to find that out.) 
I had to use the printer on a Windows machine instead.

I use Mint - it is wonderful. Keep it completely updated for about 20 
seconds a week - and never requires a reboot. Too bad more software is 
not available for Linux.

Rich,

Try removing and reseating the amplifier module several times.
Some people suggest Deoxit, but the regular version of Deoxit is not 
designed for gold plated contacts, and I don't know if these are or not. 
Use caution.

I'd blame FT8, but some guys don't have a sense of humor.

Is there an ATU involved? If so , the TX signal and RX signal are then common to the path through the ATU.  

I don't think the RX signal goes through the 100W PA. 

Also consider the antenna port switching. That is common to both RX and TX signal paths.

This was, for me, a comedy of errors. It's the first time I've 
been able to contact any relay from the New Hampshire QTH. I was 
running my KX3 6454 at 15W into a 2 element wire beam at 20' 
pointed WSW. Steve, WM6P managed to pick me up, and after 5 or 6 
round trips had mannaged to finally copy my call. Eric, WB9JNZ 
heard my call from Steve and said, "It must be Bill from 
California." Well is was down hill from there. I tried to tell 
Steve that I was in New Hampshire, but the only result was for 
Steve to say, "Will the November Hotel station come again."

Well, I just listened to the net after that and heard about 
70-80% of the stations. My noise was below S0 and some of the 
stations came through clearly without any bars of the KX3's S 
meter. Eric was the strongest station I heard at about S4 with 
perfect copy.

I also remember hearing Jim, NC0JW, my usual relay station 
weakly but clearly.

Thanks so much for the numerous responses.  A month ago a bought a 13" Dell
with "factory loaded" UBUNTU and have been very pleased with its
performance.  I'm very new to UBUNTU but have run Puppy in the past and
have been very pleased with it.  Two more questions if I may...  Is UBUNTU
compatible with the Elecraft maintenance software?  And, any thoughts about
CQRLOG logging program?   Thanks & 73...  Steve (ARS: WB4SED)   //

Rig: K3S (100W with internal ATU), s/n 11064, P3, KPA500, KAT500, into SteppIR 3-el with 30/40 loop or wire dipoles/inverted-V's. 

Problem: My K3S 100 watt internal amplifier unit (K3S/100) has become intermittent. 

It first happened yesterday while I was running 100W on FT-8. [I have done this hundreds of times, sometimes for lengthy periods, over the past 18 months with no problems.] 
Suddenly, my power output dropped to zero, and my received signals audio and P3 display also suddenly went quiet. 

After some fiddling around, I figured out that if I reduced the K3S power to 10-12 watts, both transmit and receive came on again ? leading me to conclude that it must be my 100W amp unit that had dropped out. 

I rebooted the rig and the 100W internal amp unit kicked back on. So I was hoping I had just triggered a protective circuit which had reset. The rig worked fine at 100W for a subsequent hour-long multi-band CWOPs CWT CW session at 100W. Then, however, a few minutes into the next CWT session hours later, the same thing happened again. Power output suddenly dropped from 100W to 0, and received audio and a P-3 screen filled with many medium to strong CWOPs signals simultaneously went quiet. 

I reduced the power on the K3S down to 10W, and both transmit and receive worked again, but only at low power. 
Please pass along any helpful suggestions, and thanks!

I?ve got my KX2 working with WSJT-X FT8 and am just inserting a
KXPA100/KXAT100 into the system. WSJT-X seems unhappy with CAT control - the
KXUSB cable used to connect my PC to the ACC jack on KX2 but that?s now
occupied by the KXPACBL/KX2ACBL cable combination that runs from the KXPA100
Control jack to the ACC jack. There is a RS232 jack on the KXPA100 to
connect to a PC for use of the KXPA100 Utility.

Is there a way to sort this out?

Bret,

Use the same jack on the KXPA100 as you use for the KX3 Utility.  It 
will operate the KXPA100 Utility, the KX2 Utility and any software that 
needs to connect to the KX2.

Totally agreed.  Issues with Win 10 are, in my IT experience, usually user created problems.  Yes port assignments can change, even by replugging a usb port.  To me this is of little bother, unless I was removing, then would need remote access to correct which isn't that difficult.

Victor 4X6GP

------------------------------------------------------------------------

ALL systems are targets for malware, and crypto currency mining, be
aware of that.

As for security, well, Windows 7 is OK "Now", but after Feb' next year,
as has happened within days of Win2k and XP being cast adrift, some
"new" (previously known to hackers, but unreported to MS) vulnerability
will be leveraged against Win7.   Win 10 (& perhaps 8.x) will be
patched, but 7, ?

Depends on what % of the web is still populated by W7 I guess, MS have
pushed out one or two updates to XP long after they otherwise cast it,
purely due to the severity of the issue, and the damage even a small %
of such population could cause.   The recent RDP issue I think being one
of them.

So long as your border gateway device is secure, and correctly
configured (UPnP disabled) updated and so on, you could survive running
Windows 9x, so long as you never "went anywhere bad" on the 'net, and
that's the problem.

You have in practice, little control where your browser goes.  OK, you
my point it at an otherwise trustworthy site (QRZ, QSL, clublog and so
on.)  But they have adverts on there that are served up by external sites.

Worse, many are animated to catch your eye, and also respond to the
mouse cursor moving across them.  ANYTHING that moves on screen is
running code, and THAT IS where the issue is.  That code can do anything
it wants, as well as what you see it doing.  Someone will probably know
you moved (even unconsciously) your mouse pointer over their add.

Some third party tools ("Ublock Origin" etc) can block many, but not all
of such things.  But many genuine sites that rely on the ad's to provide
revenue to cover running costs, may then block your access to the site
you want.

~ ~ ~

Re your border gateway devices...   Be prepared for some firmware
updates in the near future.  One of the popular embedded OS's used
"VxWorks" has been found to have (at least) 11 critical vulnerabilities,
and this stuff runs in billions of devices world wide, designed to be
interconnected via the web too.

See:- https://www.grc.com/sn/sn-725-notes.pdf  Then scroll down to page
9 or 10 (depending on your reader)

Note too:  New problems for exposed NAS devices, that many people are
unknowingly showing to the world!

The KPOD is subject to spills etc. Just like a keyboard. Spills onto the pad can create issues.  Amazing no one has mentioned this potential cause.

Using the K3s utility, the macros fire off 100% reliably so it's the pod switch buttons I guess. Double triggering, not triggering, sending the wrong buttons macro. It's getting worse. Looks like the hardware is not up to the task.
I wonder if Elecraft has improved the quality of performance on this item. I have had two bad ones so far and this one is probably out of warranty. I guess it's worth sending it in for repair?

I?ve never spilled. That would be an obvious caveat. But actually these buttons feel like the sealed surface mount kind.

Using the K3s utility, the macros fire off 100% reliably so it's the pod switch buttons I guess. Double triggering, not triggering, sending the wrong buttons macro. It's getting worse. Looks like the hardware is not up to the task.
I wonder if Elecraft has improved the quality of performance on this item. I have had two bad ones so far and this one is probably out of warranty. I guess it's worth sending it in for repair?

Mine is also on internal power. The interesting thing is that it is so intermittent. Probably messes up about 2% of the time.

I wonder how the K Pod is powered. Is it possible that an external supply

My new K Pod works fine on K3 s/n 0063 from internal power.

Hi.

You can "fix" regular USB<>Serial devices, to always show up at the same
COM port, when the system (re)starts, or you (re)plug something.???
Plenty of instructions on the interweb, including this which I had a
part in, that seems to work with Windows 10 & earlier.

http://www.w1hkj.com/doku/doku.php?id=howto:taming_the_wild_comport_in_windows

For Linux users, you can use "udev rules" to do the same (and more.)

I have no idea re MAC's, but you could ask about the issue on any of the
*BSD mailing lists.

HI,

Amongst my old PCs I have one (AMD A4-3330) that I have installed Ubuntu
18.04.2 LTS on.  I?m very new to Linux but I am very impressed as to how
well it works.



Following on from the thread ?Has anyone tried Ubuntu? What applications do
Linux users use with their K3 for both logging and panadapter?  I have an
SDRplay that I use with Log40M and HDSDR in Windows that could be deployed
to a Linux system if it is suitable.

Many Thanks Clive G8POC

Clive,

I?m experimenting with CQRlog on Ubuntu 18.04.  I?m to the point of rig control, CW via WinKeyer & general logging.  My rig is KX3.  The system works well.  

I?m in certain as to how much further I?ll go as my DXLABS set up on W10 functions very well. Also, I?ve not found a good contest logging program for Linux.

As far as I know, Macs don't have this problem. Those trying to 
solve it in Linux might try to understand how Apple addresses 
it. With some luck, the Apple approach is in the open source 
part of MacOS, making it easy to study. Windows users might 
approach Microsoft saying that other OSs have solved the 
problem, why does your OS still have it?

I believe this problem has been solved in Windows 10.
I've not had a problem with com ports changing with Windows 10 updates.
The problem has been with audio settings changing. The setting its self doesn't change, but the audio level at that setting changes.  When upgrading to version 1903 I had to increase the PWR (really an audio output) setting in FT8 and increase the line setting on the K3S to get 4 bars solid with the fifth bar flickering.
I think it was Don, W3FPR that mentioned some time ago that the com port assignment problem had been resolved in Windows 10. Of course I could be mistaken. If I am, someone will correct me.

That is good to hear.

Yes, with a caveat.  If your Ubuntu installation is 64 bit, a.k.a.
amd64, then some additional legwork is required to get the 32 bit
utilities running.  I have documented that process here:

https://www.n0nb.us/blog/2016/07/running-electraft-utilities-on-linux-amd64-and-multiarch/

Some of the particulars may be outdated, but as I recall the packages
were still current for Debian 10, a.k.a. Buster.

> And, any thoughts about CQRLOG logging program?

I have been using it for years.  It integrates well with Fldigi, WSJT-X,
eQSL, and Trusted QSL.  However, the current released version does have
a problem with wsjtx.  I have documented that in this Debian bug report:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932776

which references this thread in the CQRlog forum:

Yes.  I've documented that here:

https://www.n0nb.us/blog/2018/12/running-n1mm-logger-with-wine-on-debian-buster/

As for things like running another program with it like Fldigi or
WSJT-X, I've not tried that.  Ideally, it would be nice if the
communication between N1MM+ in Wine and any of the other programs
running as native Linux apps would work, but I've not tried this as of
yet.

Bob, K4TAX

I am beginning, rather belatedly, to understand the source of the many 
users reporting low Tx audio levels with the 64-bit MS Windows version 
of WSJT-X. I stated above that "Pwr" slider in WSJT-X directly controls 
the Windows audio mixer control for the chosen audio output device. That 
is no longer the case for the 64-bit version of WSJT-X on... Windows 
(built with Qt v5.12.4), instead the "Pwr" control is adjusting a 
digital attenuator before the mixer control.

There is no fix available from the Qt team because this change was 
deliberate, the problem they were solving is that the level on a Qt 
audio output stream is supposed to be separately and individually 
adjustable, that's fine if there is only one output stream to the audio 
device but if there are multiple streams then using the per-process 
mixer level is not going to work since it will adjust the level of every 
stream from that process.

To get back to the required level you must set the mixer control for the 
WSJT-X application to exactly the level of the master volume for the 
output device, do not just set it to maximum as that will potentially 
push the master level to above 0dB if your soundcard has an amplifier 
stage. To adjust the mixer level you must first initiate a transmission, 
a short "Tune" is sufficient to reveal the mixer control for the WSJT-X 
application.

I will write up a procedure, tomorrow when I am less tired, that 
explains how to do the one time setup for the audio level with the 
64-bit Windows version of WSJT-X.

I have seen it in the past on my Win 7 computers.??I also have my computers (Win 7 and 10) set so updates are only installed when I shut down, or if I ask for them before that.? I never get interrupted for updates.? The setting for that is in Windows Updates somewhere.? I'm not near my computers right now to check.Mark,KE6BB

Steve and all,

I used cqrlog for a couple years and it's impressive.  For sake of 
simplicity, however, I went back to the trio of xlog & xdx with hamlib 
support.  I made a minor modification xdx so that when I select a new 
(for me) dx, I can then paste the call into xlog.

As to Elecraft software, no, it is not compatible with modern versions 
of linux without some effort.  For some odd reason, Elecraft only makes 
32-bit binaries available.  You can load those libraries onto Ubuntu, 
but it's a lot of bloat. I chose to use unofficial 64-bit versions which 
work fine so far.

73,
Mike ab3ap

Wow - yeah!

Running FT8 30W my KXPA100 is psuging 55C and dropped to 35C with a 3" USB
fan placed on top of the fins. When the shack gets cold this Winter, I may
take the fan off again ;-)

Just curious on my part, with my K3S I ran FT-8 for about an hour making 
1 contact after another on 20M.? Power output was set to100 watts 
although the external powers meters (2 different ones) show a bit more 
than 100 watts.??? Started with PA temperature at 36?C and never saw it 
go over 50?C.?? The fan is on automatic so it normally is off but does 
step up in speed as the PA temp climbs. Still with that duty cycle 50?C, 
I believe is quite safe as 84?C is the cut-off limit for the PA.

Subject: [Elecraft] KPA500 PA current
Message-ID: <1564787023745-0.post@n2.nabble.com>

HI,

I'm new here and new to Elecraft. I have to KPA/KAT500 combo and love it! I
do have a question about PA current though...

On all bands except 20, when running full power out, my HV sits around 64v
and PA current is stable between 10 and 12A. FAn takes it's time coming on
and amp just loafs along. On 20, however, even at lower power output levels,
the PA current is high and the fan comes on and steps up quickly! At full
500W out on 20, HV is 62v and current runs as high as 16A! Even at 300w out
the current runs around 13A, higher than any other band at full 500w out.

Question is, is this just how it is or do I have something amiss on 20m?
Antenna is doublet 60' in the air and this antenna is the one I use on 80,
40 and 20, so don't think I can blame the antenna. Tuner loafs along during
all this, and SWR is no worse than 4:1 on any of these three bands.

Harry:

Are these values on a dummy load or feeding the KAT500 or antenna direct?

I just quickly checked my KPA500 into a dummy load at 500 watts output.? 
The currents run from 14.0A on 20M to a low of 11.5A depending on 
band.?? This is done with 500 watts output as shown on my Bird 43 and 
Bird 50.5 ohm load in TUNE mode which I have set for 20 watts tune power 
on all bands from my K3S.?? The HV runs 60.0 volts or a bit higher under 
load and 74.5 volts at no load. The amp is sourced from 240VAC.

With the amp feeding the KAT500 and a 1.5:1 or better resolved match on 
the antenna system, the currents run from a high of 16.4 amps to 11.7 
amps.? Again depending on band and SWR values.

Yes the amp is more efficient on some bands, and the load impedance will 
affect the PA current.? As to fans, I run mine in NOR and let the amp 
take care of itself.? Fans do ramp up when running FT-8 at 500 watts.

"On 20, however, even at lower power output levels, the PA current is high and the fan comes on and steps up quickly!"

As Bob has said, KPA500 PA current (also PA dissipation and PA efficiency) are strongly dependent of the load presented by the antenna system.   To understand what is going on you will need to know the complex load presented to the KPA500.  SWR is insufficient to characterize the load.   Avoid any load with R significantly less than 50 ohm even if the SWR looks ok.

Some of my test data is shown here - https://tinyurl.com/y37szlko

Harry,

What is your current draw when connected to a 50 ohm dummy load.
Connect the load to the KPA500 directly (not through the KAT500).

That will tell you whether the KPA500 is OK - and if so, you should 
investigate your antenna impedances - measure with an antenna analyzer.
SWR is not sufficiently informative, you need to know the resistive and 
reactive components of the load to determine whether the KAT500 is 
capable of matching it.
The KAT500 has a nominal matching capability of up to a 10:1 SWR, but at 
very low impedance loads, that can break down.

Tell us a bit more about the antenna. How is it fed? Is it properly choked to eliminate RF shield current (this is current flowing on the outside of the shield. It is a bit early to remember the proper term?)?
And, do you have chokes on the coax at the KAT500 or KPA500?

I think we need a bit more info to determine what is going on here. RF return currents flowing back into the station and combining at the KAT500 connector could account for something like this. 
Note that I don?t discount that the 20m LPF is noticeably less efficient than those on the other bands. Each KPA is unique in this sense - we tune the LPFs for best efficiency for each band. I suspect your KPA is just fine, but the more info we get from you, the more we can tell what is going on.

In any case, welcome to Elecraft products! We work hard to bring delight to your radio experience.

The data show that my KPA500 is significantly less efficient on 20 m than on the other bands tested.  Is this a characteristic of all KPA500 and, if so, why would that be the case?

I have to argue with my friend Jim on this one. The coax itself can be an antenna, and can pick up RF along its path from the antenna to the radio. The best example is a vertical antenna which will use any metal it can find for return currents, which includes the coax after the antenna-mounted choke. This current will combine with the internal shield current at the first place they are connected (which very well may be the SO239 on the back of the ATU). A choke at this point will protect against the problem. This may not be common-mode currents, which is one of the reasons I hesitated in calling it that in my previous email.

Perhaps the best way to make sure there is no current flowing on the outside of coax shield would be to add ferrites along the entire path, a solution that is way to expensive to be practical.

Andy;

This is the effect of not being able to obtain perfect components. It is easy to forget that the toroid cores used for the inductors vary, as do the windings and capacitors. There will be variances because of this which will be different from KPA to KPA. They are set up for best case operation, but then as components age things will change. As it is, the design is outstanding. With efficiencies greater than 50%, the designers did a super job!

Jack,

I understand that there will be variation between different KPA500.   However, 2 owners have reported that 20 m stands out as being less efficient than other bands.  I was asking if that is typical of all KPA500.   I don't really expect to get an answer though as I doubt many owners have test data as comprehensive as mine.

I just did a spot check on 20 m and, despite my line voltage being down to 118.1 V with the high air conditioning load in the area,  I saw 60% efficiency with load R 51 X 0.4:

PA voltage=58.9
PA current=13.8
PA input=812
RF out=490
PA diss=322
PA effic=60

Of course this is not typical of normal operating conditions.

73,
Andy, k3wyc

Yes, it can, and it is good practice to break up feedlines to high 
dipoles to prevent their interaction with adjacent vertical antennas; a 
choke acts as an egg insulator.? I first published this recommendation 
about ten years ago. It is also good practice on long runs from 
receiving antennas to prevent noise and TX RF from coupling to the 
inside of the coax by a limitation of the shield quantified as its 
transfer impedance. This is especially important with the relatively 
thin shields of CATV coax we commonly use for RX antennas, which are 
especially poor shields below VHF. But, again, these chokes should be 
along the line outside the shack.

But NOT on a feedline in the shack! Think about it -- coax feedlines 
should be bonded to the premises ground system at the point of entry.


> The best example is a vertical antenna which will use any metal it can find for return currents, which includes the coax after the antenna-mounted choke.
An antenna should NEVER depend on the feedline to carry return current, 
and an effective choke prevents this. Further, a path for return current 
should be provided by some sort of counterpoise, the most effective of 
which is a radial system. Also, you're describing a type of vertical fed 
from the base. There are many vertical antennas that approximate center 
feed.? They are discussed in these slides for another talk I've given at 
Pacificon, Visalia, and some ham clubs. 
http://k9yc.com/VerticalHeight.pdf and in this pdf, which ran in The Jug 
several years ago. http://k9yc.com/AntennaPlanning.pdf
> This current will combine with the internal shield current at the first place they are connected (which very well may be the SO239 on the back of the ATU).

If that's the first point of connection, you've got a VERY unsafe 
station with respect to lightning!? RUN, do not walk, to buy N0AX's 
recent ARRL book on Grounding and Bonding, to which I contributed 
extensively. Or study these slides for a talk I've given at Visalia, 
Pacificon, and several local clubs. You'll find it referenced in Ward's 
book.

> A choke at this point will protect against the problem.

The only thing chokes do in the shack is reduce RF current from coupling 
to or from poorly designed equipment by a mechanism called "The Pin One 
Problem" by the audio professional who first described it, Neil Muncy, 
ex-W3WJE (SK) in 1994.? I've seen it in virtually every piece of ham 
gear where I've looked for it, including all the Elecraft products I've 
examined, even the KRC2 band decoder.

Is the K-Pod's data cable a standard data cable?  I'd like to use one that
is a bit longer than the stock cable so am wondering if I can just
substitute a standard one.

Jim,

Refer to the K-Pod manual.

You must cut one of the wires to use with the K-Pod.

Most likely source of this will be Elecraft. Those who bought these replaced the 2.7 KHz standard filter. You?re more likely to find spare 2.7KHz filters.

So the K4HD will have an SSB and a CW Crystal filter in each of the two

my K3 and my K3s can I use those pairs in the new K4HD ?

I believe a similar question was answered a month or so ago. I think the answer was ?Yes?. K3 filters will work in a K4HD.

Subject: [Elecraft] Fan for KXPA100
Message-ID: <201908050333.x753XfLh027727@mail42c28.carrierzone.com>

I mounted my KXPA100 in my truck under the back seat for mobile 
operation.  Ford made a nice lockable compartment accessed by tilting 
up the seat and the amp just fits but the seat bottom rests on the 
top of the heat sink fins.  As we were traveling thru hot weather, I 
was concerned there would be enough air flow so I attached two 1-1/2 
inch square fans on the connector end of the amp to force some air 
thru the fins.  I used the spare power-pole connector for 12v power 
which runs when voltage is applied to the amp.  I also cut several 
3/4 inch holes in the sheet metal seat base for air flow to/from the truck cab.

It survived running 80w on 6m-SSB so guess its enough (I did not monitor temp).

I have the amp connected to the KX3 for remote control (nice when mobile).

Adding a fan to solid state amps is good insurance (esp. when running digital).

Wow - yeah!

Running FT8 30W my KXPA100 is psuging 55C and dropped to 35C with a 3" USB
fan placed on top of the fins. When the shack gets cold this Winter, I may
take the fan off again ;-)

Bret,

I?ve just submitted a review of the AX1 to Practical Wireless magazine, which should appear be in the October issue, published end of September.

I found it worked well on the tripod. The key to getting the most out of it is to let the counterpoise wire fall to the ground about 3 ft or so from the radiator. As a very short base loaded antenna, I don?t think an extra foot or so of height will make a lot of difference. Your extra counterpoise wires is probably the best thing to do. More details in the article

Many USB>Serial cables contain counterfeit chips.  The legitimate makers 
fought back by installing driver instructions that disable the 
counterfeit.  Maybe your update finally caught up.  The Elecraft cables 
are legitimate.  Don't buy cheap knock-offs from the Internet.

Neil,

Does 60 meters work, but not 40 meters?

The only things that could 40 meters to fail after installing the K60XV are:

1) C6 is not the correct 4.7 pF value - it will be marked either 4.7 or 479.

2) Relay K1 not working properly, check the orientation and soldering.
3) P2 and/or RF J15 not installed properly.

73,
Don W3FPR

This is an update for the group re. my KPA500.Several weeks ago I reported that all of a sudden my KPA500 dropped to 0 watts out when fed with my K3. SWR was 1:1. When the amp was placed in bypass my K3 showed normal output. When placed in operate SWR showed 99:1 and K3 dropped to 0 watts out.After speaking with tech support I obtained a RSA and sent in back for repair.Elecraft reported problems with the TR circuit and performed the following:Updated the TR circuit and rebiased PA module to 0.8 AThey replaced C9 for QSK upgrade in the I/O ModuleReplaced C20, R35 and R31 for QSK upgrade in the Front Panel ModuleReplaced Q5, D7, R3, R9, and R24 for transmit/receive MOD in the Low Pass Filter and replaced C43 and C44 in the 12 meter low pass filter.After 8 hours of burn in and thorough testing, Elecraft returned the KPA500 back to me and only charged for one hour of labor and return shipping. Wow!!!Am I a happy camper/customer... you bet. When Ten Tec disappeared for awhile I reluctantly switched to Elecraft, but have never looked back.?What a wonderful company with outstanding customer support. I look forward to adding a K4 within the next year...Don, W4CBSSent from my Sprint Samsung Galaxy Note9.

Don -

I have nearly the same exact problem with a KPA500 that is only 2 weeks old.  It lets the signal pass thru on Standby, even showing proper signal levels.  But in Operate mode, it's unresponsive and the SWR skyrockets to 99:1.

I ran tests suggested by Support, but no joy.  I will be shipping it back to Elecraft tomorrow.

Coincidentally, the "front end" of my 2 y/o IC7300 died at the same time, yielding zero receive (everything else is fine).

Lyn, W?LEN

Subject: [Elecraft] KPA500 no output

This is an update for the group re. my KPA500.Several weeks ago I reported that all of a sudden my KPA500 dropped to 0 watts out when fed with my K3. SWR was 1:1. When the amp was placed in bypass my K3 showed normal output. When placed in operate SWR showed 99:1 and K3 dropped to 0 watts out.After speaking with tech support I obtained a RSA and sent in back for repair.Elecraft reported problems with the TR circuit and performed the following:Updated the TR circuit and rebiased PA module to 0.8 AThey replaced C9 for QSK upgrade in the I/O ModuleReplaced C20, R35 and R31 for QSK upgrade in the Front Panel ModuleReplaced Q5, D7, R3, R9, and R24 for transmit/receive MOD in the Low Pass Filter and replaced C43 and C44 in the 12 meter low pass filter.After 8 hours of burn in and thorough testing, Elecraft returned the KPA500 back to me and only charged for one hour of labor and return shipping. Wow!!!Am I a happy camper/customer... you bet. When Ten Tec disappeared for awhile I reluctantly switched to Elecraft, but have never looked back. What a wonderful company with outstanding customer support. I look forward to adding a K4 within the next year...Don, W4CBSSent from my Sprint Samsung Galaxy Note9.

Subject: [Elecraft] K3 Amplifier Drive Inconsistency
Message-ID: <CAFyNi84ZDRSTR9UXuY6D+x0bTJhSC8zrAQexzo=ogT6sf4JEzw@mail.gmail.com>

I need help solving an amplifier drive inconsistency problem when I operate
using digital modes on 50 MHz.  I noticed during a recent contest that the
K3 will sometimes key the amplifier but provide zero drive. I'm using K3 SN
669 on 50 MHz FT8, FT4 and MSK 144 and driving a KPA1500 to about 750 watts.

After several consecutive transmissions I notice that the amplifier
responds briefly to being keyed but the power drops to zero. It's keyed up
but has no output.  The K3's output (drive) is set at 17 watts but there is
no output on the RF meter when this happens. The K3's red TX indicator is
on. This problem also occurs when driving a KPA500, though less often

I can correct this problem temporarily by switching the amplifier to
standby, which allows the K3 to  change to "barefoot" output then switch
the amplifier back to "operate" which changes drive power back to it's
preset level.  That's usually good for a dozen or so transmit cycles before
the problem reappears.

This problem does not occur when driving other amplifiers; nor does it
occur when using CW or SSB modes. It seems to have something to do with the
K3/KPA1500 command interface controlling the output power of the K3.

Any ideas?

Hi Bill, 


I've never experienced your reported amplifier drive problem with 
my K3 s/n #6100 driving 20 watts into my Lunar Link LA-62 
1500 watt output 6 meter amplifier. Perhaps it unique to the 
K3 - KPA1500 combination.

Folks,
     When I go to the Elecraft site and search on KDVR3, I see the digital recorder board come up for $169.  If I search on E850246 (which is the DVR board assy number), I am shown a K3DVR PCB for $365. If this is not a mistake, what?s the difference between these two boards?

Last night I noticed I had little to no output from my KX3/KXPA100 combo
especially on 40. I did a little experimenting and discovered that 3 turns
of the transmit audio line through an unknown mix clamp on ferrite fixed
the problem. Without it I was mildly affected on 20 and not at all on 15.
With that choke in place I was stable on 40 and all other bands I tried. I
am currently portable for work (in North Dakota) and am using a mobile
antenna clamped to the top of a 6 ft tall wooden fence. Without the choke
the ALC would go up when keyed, then drop off to near nothing. I know AFSK
is becoming a more preferred method of generating RTTY, but I have never
had this issue with FSK. So I learned a lesson about the little USB
soundcard I use for portable ops.

Jim,

That sounds like RF getting into the audio.  Try moving the ferrites to 
the antenna feedpoint to choke off the RF on the coax shield.  Yes, the 
coax from a vertical needs a current choke.  In fact, you may need a 2nd 
choke at the shack entry point as well.  The coax will try to be an 
additional radial and that means it will have RF current on it - if not 
from the antenna itself, the radiation from the radiator may couple with 
the coax shield and cause RF on the shield (that is why the additional 
choke at the shack entry).

The KX3 has one characteristic that may cause confusion.  If the signal 
to the mic input is too large, the KX3 will shut down the audio gain 
giving the impression that there is not enough audio when in fact there 
is too much signal at the input.

73,
Don W3FPR

Thanks for the suggestion. The antenna is less than 25 feet from the rig.
The RF getting into the audio could be coming from the coax or the antenna,
no way to say which. There is 5-6 turns of coax, 6 inches in diameter, a
couple of feet from the rig where it comes into the apartment.  Beads on
the coax might do the trick, but I am not near my parts boxes, they are
about a 12 hour each way drive away. And I am in very rural North Dakota,
would have to order something mail order and wait till pony express gets it
here. So I will stick with what works. I am in a tiny apartment with just a
little patch of weeds with a little grass on it and can't get the antenna
any further away. I had the same problem when I tried a short dipole with a
fair balun (elecraft of course) at the feed point. And, as I said, I now
have zero problems. Well, other than a crappy antenna setup.

That mobile whip is only half of an antenna. When used on a vehicle, the 
metallic parts of the vehicle provide the other half, a path for return 
current, which is called a counterpoise. If you provide no counterpoise, 
return current will flow on the outside of the coax down into your shack.

The solution to your problem is to 1) provide that counterpoise, 
possibly in the form of one or more resonant radials (more is better); 
AND 2) put a proper ferrite choke at the antenna feedpoint so that the 
coax doesn't carry return current. See http://k9yc.com/2018Cookbook.pdf 
for detailed advice on chokes.

I would like to use JS8CALL on my Raspberry Pi 3B+ , so do I need to use my SignaLink as well?? Has anyone on this group used a Pi3 with JS8CALL connected to their KX3??Getting the KX3 connected to the Pi seems problematic; I have all the connectors from Elecraft, the program is loaded on the Pi and seems to operate properly, but doesn't seem to work with the KX3. I will need to get a GPS HAT for the Pi and I'm considering the PI HAT from North West Radio that includes a built in GPS with antenna.?Thank you in advance for any input ...

Bob, K4TAX


          An article by two well-known radio amateurs, ?Tuning
          Electrically Short Antennas for Field Operation,? appeared in
          Microwave Journal. Authored by QEX Editor Kai Siwiak, KE4PT,
          and award-winning researcher Ulrich Rohde, N1UL, the article
          points out that both Amateur Radio and military applications
          exist for 20-W battery-powered radios equipped with whip
          antennas. ?In general, the whip antenna which makes the radio
          portable is not optimized for signal propagation: A whip
          antenna has no ground return or proper counterpoise,? the
          article notes. ?While some users drag a wire of up to 8 meters
          behind, this is not an ideal solution.? As the article
          explains, electrically short antennas ? typically 0.1 ? or
          shorter ? look like a capacitor, with a typical capacitance of
          25 pF per meter of length. ?At 2 MHz, where the wavelength is
          150 meters, an inductor of 84 ?H is required for resonance,?
          the article says. But just getting a good VSWR is not all
          there is to it. Rohde told ARRL that loading coil placement in
          a short vertical antenna is critical, and ?the greater the
          elevation of the coil, the better the radiation. He said that
          ?center loading? ? he considers the ?best compromise? to be
          more on the order of two-thirds? loading ? can dramatically
          affect both the antenna?s transmitting and receiving
          performance, as opposed to base loading, as found with popular
          so-called screwdriver antennas. Radials of some sort also are
          essential. As the article points out. ?With center loading,
          both the radiation resistance and integrated surface are
          larger, which are better for radiation.? Inductors are the
          lossy components of an antenna tuner, while capacitors ?are
          infinitely better.? The authors conclude that, for optimal
          operation, antenna radials should be 0.25 ?, with one
          sufficient for tuning, and up to four producing a symmetrical
          azimuth. ?Connecting the HF radio ground to a large metallic
          object is a good choice,? the article said. Ulrich told ARRL
          that optimizing an antenna in the manner the article describes
          will produce ?significantly better? signal reception, although
          a short antenna will also have a narrower bandwidth. The
          objective should not be to get a good VSWR but to keep in mind
          that there?s a difference between resonance and radiation.
          ?These requirements for optimum antenna performance make HF
          manpack radios somewhat complicated and unattractive,? the
          authors concede.. ?Nonetheless, the well-matched and radiating
          antenna provides the most success, and some of these highly
          portable radios provide vital communications in disaster areas
          ? recently in Puerto Rico and South Florida.?

You should buy yourself a copy of the ARRL Antenna Book and learn about 
how to build your own antennas.

That tube contains a lot of little ferrite beads that act as a common 
mode choke. This form of choke was developed many years ago by W2DU (now 
SK). If you haven't already fried it by running 500W you probably will 
eventually.

If your QTH allows more than one antenna, I strongly recommend the use 
of resonant fan dipoles fed with coax. They are very easy to build. If 
you do that, you can build your own common mode choke that is far 
superior to the one you bought with the antenna. 80 and 40 M makes a 
good combination for a fan, and the 40M element will work on 15M. If 
you're limited to 100 ft or so, consider one of the loaded 2-band 
dipoles built by Hypower Antenna Company (a ham in his basement), or buy 
the loading coils and build your own. I used one of his 80/40 loaded 
dipoles in Chicago. It also worked on 30 and 17. A 20M dipole is only 33 
ft long, so it's pretty easy to rig almost anywhere. I wouldn't worry 
about 15, 12, or 10M for the next 4-5 years, because they're nearly dead 
as we approach the bottom of the current solar cycle.

There are several "how to" tutorials on my website, k9yc.com/publish.htm 
, including one that describes how to build fan dipoles from inexpensive 
and readily available parts. My guidelines for chokes is at

It is possible that the ferrites are heating. If that is the case, you could test it by transmitting a steady carrier for a minute while watching the SWR. If it?s heating, there should be a gradual rise.
Twin lead will change characteristics significantly when it gets wet. So will ladder line, although not as much. So if this happens when it rains, that?s the issue.
There is also the possibility that there is a badly corroded connection inside the balun which opens when something expands due to heat. I once had this problem with what seemed to me to be a very well-constructed bead balun. The connection to the coax connector was the culprit. It was hard to find because it was intermittent.
If you replace the twinlead with ladder line, it will need to be slightly longer because the ladder line has a greater velocity factor than the twinlead. The Vf of twinlead is about 78% and of ladder line 91% so it will be longer by a factor of 1.17.

It comes to mind I have an Elecraft T1 ATU I might try attaching directly to
the base of the AX1 rather than relying on the KX2 ATU 25-40ft from the
antenna. I try to operate closer but sometimes have to run that RG58 to
clear obstructions. Thoughts?

"It is possible that the ferrites are heating. If that is the case, you could test it by transmitting a steady carrier for a minute while watching the SWR. If it?s heating, there should be a gradual rise."

I have data for SWR runaway events that I believe were caused by heating of the ferrite cores in a common mode choke.  The SWR change for these events was not gradual.  It was closer to exponential.  Once runaway starts SWR reaches the point that it trips something in just a few seconds.   The ferrite choke was in easy reach (outside but only 5 feet above ground) and nearly burned my fingers.  Made me think about oil immersion for cooling but have not tried that.  Instead I set a lower max power for that antenna.

KPA500 can be protected from these events by setting KAT500 key interrupt threshold to a value lower than the SWR that trips the KPA500.  My series of runaway events, and my attempts to protect against them,  exposed a defect in the KAT500 utility so installation of the latest version may be required.

Data for one event:

"SWR runaway and choke cores too hot to touch several minutes later.
470 W 160 m FT8 with multiple transmissions before onset.

I did a lot of testing with a tuner followed by a high-quality DX 
Engineering balun in a system with high, reactive SWR. I did not push it 
far enough to destroy the balun, but I did note a gradual increase in 
SWR. And yes, the rate of increase sped up as it got hotter. So I 
suggest testing just long enough to see the process start!

In your data, the SWR decreases and then increases. I started with the 
tuner set to provide an SWR to the transmitter of 1:1 so it could only 
increase.

Incidentally, I found that the balun ran much cooler if the reactive 
component of the line's impedance was canceled out by a balanced pair of 
(in this case) capacitors.

Subject: [Elecraft] K3 & P3 For SALE $1950!

 I have an Elecraft K3/100 HF radio at 100Watts SN000348 with the matching P3 Pan adapter! The K3 has the following options: KAT3A ATU, KTCX03,KBPF3A,KIO3,KXV3 and the following Inrad filters KFL3A-400, KFL3A-2.1K and KFL3A-2.8K  These are from a non smoking home and they also have the matching Side KX extended end panels to protect the front and back of the radio. (included are the factory end panels). The radio works all modes and decodes CW and other digital modes. The Pan Adaptor has the VGA board option so you can put this display on a TV or large computer screen. This package will also include the cables and manuals for both. I prefer local pick up as I don't want to damage these in shipping.  $1950 for all!  If I need to ship these then another $50 to cover costs.  73 Scott AK6Q

Wayne (or anyone),

 

I have a rather specific question.  When I operate locally with a K4, I need
an RS-232 connection to the local computer/accessories but when I'm remote,
I will only need the K4's ethernet connection.  Can the K4 have BOTH enabled
simultaneously?  In the K3S, it is one or the other (USB or RS-232).

 

Thanks,

Bob K5WA

"In the K3S, it is one or the other (USB or RS-232)."

That limitation is surprising to me.  My Kenwood TS-590S allows simultaneous use of USB CAT and COM CAT.  My current station architecture would have been much more difficult to implement without that capability.

Yes. The K4 can be controlled over all of its I/O ports simultaneously: Ethernet, USB (with two virtual serial ports), and separate RS232 (DE9 connector). We use an internal server architecture so all remote clients have independent access.

Bret,

Yes, the T1 mounted at the antenna will reduce the potential loss in the 
coax.

Will you notice the difference?  Maybe or maybe not.

I think a T1 at the base would make a noticeable difference if the coax were more than a few feet long and the whip's resonance well removed from the target operating frequency. Short whips can be extremely narrow-banded.

If that turns out not to be supported, there are ethernet<->serial
adapters that are used to provide remote console ports on web servers.
I think Black Box, Raritan, and others make them.

Michael,

I have good luck using my KX3 with a Raspberry Pi 3B+ and also the new Raspberry Pi 4 for both JS8Call and WSJT-X. I use an inexpensive USB audio adapter/sound card and standard stereo 1/8" (3.5mm) male to male cables connected between the MIC and PHONES jacks on the KX3 and the sound card. To listen to the receive audio and monitor transmit audio, I split the PHONES output using an 1/8-inch "Y cable" and feed one side to the sound card and the other side to a powered speaker. For CAT control and PTT via CAT I use the standard Elecraft USB serial cable from the ACC1 jack to a Raspberry Pi USB port.

In Settings on the Radio tab, under CAT Control, I choose the K3/KX3 or KX3 as the rig and /dev/ttyUSB0 as the serial port. You'll also want to match the radio serial port settings, typically, 38400, 8, 1 and none. On the Audio tab, under Soundcard, I select Default:CARD=device for both Input and Output.

This method may result in some low-level 60 and 120 Hz audible ground loop hum when AC powered, particularly with the powered speaker connected, but the transmit signal, at least in my case, is clean. You can certainly use a SignaLink or equivalent unit for better isolation and level control, but I've found that the little USB audio adapter/sound card works fine and is a really compact solution for portable operation!

I would like to use JS8CALL on my Raspberry Pi 3B+ , so do I need to use my SignaLink as well?? Has anyone on this group used a Pi3 with JS8CALL connected to their KX3??Getting the KX3 connected to the Pi seems problematic; I have all the connectors from Elecraft, the program is loaded on the Pi and seems to operate properly, but doesn't seem to work with the KX3. I will need to get a GPS HAT for the Pi and I'm considering the PI HAT from North West Radio that includes a built in GPS with antenna.?Thank you in advance for any input ...

Michael,

I have had no issues using the Raspberry Pi without a GPS time reference. As long as you have an internet connection when the RPi is powered up, the internal clock should be close enough to use for hours. In the field I use my iPhone as a WiFi hotspot for an internet connection to the RPi.

I am wondering if there is a command sequence string that will play a

Thanks very much for pointing me to the right place, Mike.  I also received
an off-list reply from Dennis, saying the same thing.  I recalled seeing
those, but didn't know what I was looking at, I guess.  Now I don't have to
lean forward to push the button.  I'm calling it "ergonomic conservation".
That sounds better than "being lazy":-).

Thanks again!

Subject: [Elecraft] KPA1500 Remote Software Setup
Message-ID: <3a150c62-33f1-a40b-9fdf-a97c4900c28f@bellsouth.net>

I am trying to set up the KPA1500 Remote Software to access my KPA1500 
from a distant location over the internet. Some questions:

Will I be successful using a reserved IP rather than a static IP?

The laptop I plan to use as a server is on the same LAN as the KPA1500. 
When I click the Host Remote tab on the KPA1500 Remote software and 
enter the amplifier's IP clicking the test button finds the KPA1500. The 
Server Setup box is pre-filled with Port 4626. The instructions 
downloaded from Elecraft say " If connection (Connect Remote ) is from 
outside the LAN, TCP port (4526) must be opened and forwarded." What are 
the internal and external ports that need to be forwarded? Is it the 
public IP of the router to which they need to be forwarded? Are the 
Username and Password prefilled as admin what I will need to connect 
from the computer attempting to control the amp over the internet?

On the Connect Remote tab the Host/IP is the public IP of the laptop on 
the LAN with the KPA1500? User and Password are those entered in the 
Host Remote tab?

Sounds like an idea worth trying ? I have always wondered about the coax loss between my KX3/KX2 and my portable antenna no matter which one it is (i.e. AX-1, Wire and counterpoise wires, Buddipole, etc.).

But, really glad I did not sell the T1 on several occasions of thinking about selling it.  I have not used my T1 since I sold my KX1 almost three years ago.

Rather little of this discussion makes sense to me.

Let's look at this realistically:

1.? The antenna tuner in the KX2 is rated to be good up to 10:1 SWR.? 
Let's assume it's good to 15:1.

2.? Let's assume you're using a decent cable for portable operation like 
RG-8X.

3.? Let's assume that the length of your coax when operating portable is 
not much more than 30 feet long.

4.? Let's assume under the current solar flux conditions you're spending 
most of your time on 20m or lower in frequency.

30 feet of RG-8X has a loss of 0.4 db or less for that length at those 
frequencies, and per the charts in the link below the additional loss 
due to a 15:1 SWR is no more than 2 dB.

http://www.astrosurf.com/luxorion/qsl-transmission-line2.htm

Maybe it's just me, but I don't think that justifies dragging along a 
remote tuner.? You could recover a heck of a lot more dB by simply 
bringing a somewhat larger portable antenna.

Dave?? AB7E

You need to take into account the radio finals. When the SWR is high, My
KX3 cuts back because it gets too much reflected power. I expect the KX3,
and in fact any other radio or amplifier is similar. 15:1 is about half the
power coming back.

Probably. I use neither one. I use a standard, dynamic IP address with a
remoterig ddns server to keep it up to date. Works fine, with no need to
reserve an IP or get a static address.

On the router that controls the LAN on which the KPA1500 resides, forward
port 4626 to 4626 on the server that is running KPA1500 Remote. (You said
4526 in one place above; I think that was a typo.) Specify the local IP
address of that server, typically 192.168.x.y.

no - see above

The connection parameters on the control side need to match those on the
server (amp) side. You can use the default "admin" or specify your own
username and password. Also specify any port number, so long as it matches
on the control side, amp side, and amp side router port forwarding table. I
use the default 4626.

You specify the external IP address of the LAN on which the server resides.
If it's static, it won't change. I don't know how "reserved" works. As
mentioned above, I use the remoterig ddns server to maintain a dynamic
external IP address, so the string I use looks like this:
      xyzzyyyy.ddns.remoterig.com
where "xyzzyyyy" is the coded 8-character string that RemoteRig gave me
when I set up to use its ddns server. If you don't use RemoteRig boxes, you
might prefer to use a public ddns server or, as you suggest above, a
reserved or static IP address.

Yes, they must match.

I haven't been following this thread closely but I think Dave makes good 
points.? As to the final fold-back, if I waded through this correctly, I 
understand that the OP has the built-in tuner in his KX2.? That solves that issue.

BTW, SWR = 15:1 is a return loss of about 1.1 dB, not 3 dB.

Yeah, i didn't catch that he was going to use the internal tuner and just
forgo the external one at the other end of the coax.

In that case, I agree with Dave.

Doesn't much matter.? You're still talking a 3 dB difference at most (50 
feet vs 30 feet), and while I will be the first to argue the benefit of 
every single dB for normal station operation (see 
http://www.ab7e.com/weak_signal/mdd.html), I don't understand the angxt 
over that 3 dB for portable operation.? If that's actually a concern, 
bring a better antenna.

Some points?

??dragging along a remote tuner?

Surely you are kidding or you get the award for hyperbole of the day.  The T1 fits in my shirt pocket!  It is zero effort to bring ? no ?dragging? required.

And, I operate with 50 feet of coax because carrying multiple different lengths of coax on various trips where I operate portable does get into dragging.  There have been some situations where 50 feet has not been enough such as in one national park where the convenient picnic table was quite a distance from the nearest convenient tree.

Scroll down to the original post.? We were talking about a KX2 with an 
internal antenna tuner.? Presumably the tuner works as it should to 
present the proper load to the finals.

The SWR could easily exceed 15:1, depending on the operating frequency (short loaded whips can be very narrow banded) and other factors that apply to portable operation such as radial configuration, ground characteristics, and antenna height. 

Even 2 dB matters when you're using QRP.

Then you'd be using the T1 to partially drop the SWR on the coax, but it 
still wouldn't be anything close to 1:1 unless the T1 has a much broader 
range than the tuner in the KX2.? You'd still have some additional coax 
loss due to SWR (but less loss, of course) and you'd still need the 
tuner in the KX2 to get a match that wasn't a problem for the KX2.

I have to wonder how much loss there is in two tuners each trying to 
match a really bad load, and it still seems to me that the better 
approach if you're worried about every dB is to use a better antenna.? 
Using a really short whip like the AX1 with 50 feet of coax and two 
tuners seems like a poor choice of tradeoffs.

73,
Dave?? AB7E

Why not?  K3(s), KX3, and KX2 all support 60M band. 

And,K4 has continuous coverage from 100KHz to 54 MHz.

Hi Wayne:
will I be able to totally eliminate the use of the RemoteRig boxes with the
K4 when operating remotely? Will I need specific software for remote
operation for win10 PCs? Will I be able to control and monitor the KPA1500
directly through the K4?

Dave And All,

 

Hmmm!  I don't quite understand that statement.  Why would you worry about
every dB at your home station but not necessarily be concerned on a portable
setup???  I guess maybe you are saying that, when operating portable, just
get the best antenna possible as opposed to a lesser one.  Well, that's
ideally true, but "you do with what you got"!  Whatever antenna you might
have for portable use, you want to squeeze every dB you can out of it!  I
tend to think it could be even more important when operating portable since
you already apt to be weaker, and that last dB may be the one that gets you
heard!  Home station operators might  actually ignore such issues since they
may already be more than loud enough to be heard.  QRP/portable operators
tend to not have that luxury.

Doesn't much matter.? You're still talking a 3 dB difference at most (50 

feet vs 30 feet), and while I will be the first to argue the benefit of 

every single dB for normal station operation (see 

http://www.ab7e.com/weak_signal/mdd.html), I don't understand the angxt 

over that 3 dB for portable operation.? If that's actually a concern, 

bring a better antenna.

I suspect that Wayne and Eric would take a big exception to the use of the Elecraft name in their obvious knock-off product.

I could never get used to the KX3 KXPD3 paddle, so I bought an AME Porta Paddle (much better for me). I am offering my KXPD3 for sale, complete with original data sheet, both hex wrenches, and the 2 extra springs (firm is installed). All is in the original zip bag. The wire mod has been installed (errant dit issue).
It?s a good little paddle, just not for me.

Sent to you for $85. Paypal ok.

Interested? Email me.

Thanks and 73?

Jim,

Excellent and comprehensive info on your website! Everyone should take a look at it.

In my setup, the power supplies for the KX3, Raspberry Pi and powered speakers are the typical 2-wire, no ground, switching supply in a plastic case, so ground potential is established through the audio interconnect. The rig and computer connect only through the USB ports for the USB serial adapter and the USB audio interface. After a little experimentation, I realized The ?hum? I was hearing was RF getting into the powered speakers on transmit with the antenna I close proximity to the KX3. Moving the antenna away from the rig resolved the issue.

This is a little off-topic, but may be of interest to the audio geeks on the list...
I worked in TV engineering here in Nashville for many years, and we dealt with a lot of music recorded in big studios, and thus long cable runs and a lot of channels of audio. It was all analog in the early days and several audio engineering luminaries helped me immensely. One was Allen Burdick of Benchmark Media Systems. His ?Clean Audio Installation Guide? is still indispensable:

Deane Jensen of Jensen Transformers fame and his prot?g?, Bill Whitlock, were two others:

And a local genius, Dave Harrison, who designed an built the legendary Harrison Consoles that we used extensively:

Power line hum and buzz can be prevented by 1) getting power for all
interconnected equipment from the same AC outlet, or from outlets whose
Green Wires are bonded together, AND 2) bonding from chassis to chassis
of all interconnected equipment, AND 3) proper bonding of all grounds in
the home, including ground from that interconnected equipment in the
shack. All three are necessary. There's a tutorial on this at

Well, I actually have three reasons why I think the root of this 
discussion has been misguided:

1.? Typical portable operation is for casual fun while camping or just 
enjoying the outdoors.? Squeezing out every last dB doesn't quite fit 
that scenario.

2.? If you are trying to squeeze out every last dB for whatever reason, 
using an AX1 with 50 feet of coax and an extra tuner isn't the way to do 
it.? There are better choices for the same size and weight budget.

3.? And if you are using the AX1 with its very high Q, there are lots of 
other variables (length of counterpoise, terrain, height above ground, 
proximity to other detuning influences, etc) that will have far more 
impact on transmitted signal strength than a couple of extra dB loss due 
to SWR on the coax.? Wayne made pretty much the same comment in the 
context of SWR, but the same holds for signal strength.

Use whatever you want.? It makes no difference to me other than the 
misconceptions that come with it.? I've done a LOT of portable operation 
over the years, and my first priority has always been to put up the best 
antenna I could within whatever constraints I had at the time.? I don't 
own an AX1 but it appears to be a fine antenna for its intended purpose, 
which was essentially a backpacker antenna usable even for pedestrian 
mobile.?? However, if I was on a camping trip (tent, cooler, etc) and 
wanted to get out better, I can think of better options.? I do own a KX2 
and I use it with a homebrew 20m vertical that I can easily carry in one 
hand for miles (five 4' sections of lightweight tubing, one of which is 
for elevating the radials) and set up in fewer minutes than I have fingers.

73,
Dave?? AB7E

I have available, a small quantity of a very useful, but slightly different  BNC "T" connectors.
Just picture a normal BNC "T", but with the male end swapped with the one of the female ends.

What makes this useful is that with the male end plugged into your K2/K3, a right female points up for your loaded whip, AND the other female, straight across from the radio's connector can have a  BNC to two pole banana adapter for easy connection of a counter-poise or ground wire.

I can supply these at $10, shipped anywhere is the US.

Is there an issue with the KPA500 being OFF with power up -> booting of the K3?  Does it need to be actually powered up, i.e. and in operational state?  OR is just having it in the ?sleeping? state (REAR switch ON, FRONT PANEL SW-OFF) OK?

I know about KAT500 and AUX-BUSS stopping K3 bootup, and have an ?automatic? solution that works great.

Thanks. I knew Allen Burdick, who died quite a few years ago. Bill 
Whitlock and I still serve on the AES Standards Committee, and are 
principal authors of AES Standards on EMC, and I've been Vice-Chair of 
the EMC Working Group for about 15 years. The first draft of four of 
those Standards started out with Neil Muncy and me around my kitchen 
table. Bill and I have taught EMC workshops together. Bill is far more 
than Deane's protege -- a fine engineer in own right. Deane was a fine 
engineer, and published some important work before he died.? Bill, Neil 
Muncy, and I were elected Fellows of the AES, partly on the basis of our 
EMC work.

I retired about ten years ago from a career that started in broadcasting 
and ended in pro audio. When Neil Muncy died, I was asked to take over 
the EMC workshops that he had taught for many years at conventions for 
sound contractors, and continued that until about four years ago. Slides 
and a White Paper are on the pro audio section of that publications page.

Ben,
You no longer have to worry about the KAT500 stopping the K3 power on. That was fixed in a 4.xx firmware update eons ago. If you have a 5.xx firmware version in your K3 you have nothing to worry about.
As far as I know there never was an issue with the KPA500. I never had any issues with my KPA500 and after loading the updated firmware no issue with my KAT500 either.

73,
Mark, WB9CIF

I believe it is made in California - but I don't know about the whip.
Wayne will correct me if I am wrong on that.

It doesn't seem obvious at all to me that it's a knockoff.? There are 
only 2 units available and he's asking way too high a price for a knockoff.

Message-ID: <2176b09e-601e-2433-bbae-20c8888917a1@comcast.net>

Recently bought a used K3s with the 2-meter option factory installed, 
which I have no plans to use. According to Elecraft, this is compatible 
with K3's above serial number 3000, and all K3s'. The K3s went to 
Elecraft in Jul 19 and got a complete checkup, including the 2-meter 
module. I tested it with a dummy load and it appears to work. This will 
include all the parts I removed from the K3s, as well as a KFL3B-FM 13 
KHz filter. The price has been adjusted a little lower in the event you 
need to order some additional parts. PayPal preferred. $375, including 
USPS shipping. John, N0TA

Check your cables. It may be that you are using a straight-through cable with the power pins connected between the K3 and the KPA. These two pins (pin 8 on both sides) must not be connected.

KAT500 sleeping (12v supply connected, power button "off") is fine.

The problem occurs when the KAT500 has no 12V power; it pulls down the AUXBUS pin. 

K3 MCU firmware was changed to display a reminder if the AUXBUS is held low for too long during startup.

>From K3 firmware release notes:

MCU 4.93 / DSP 2.83, 10-16-2014

* KAT500 POWER-ON REMINDER ON K3 DISPLAY: If a powered-off KAT500 is pulling the auxBus signal low when the K3 is first turned on, "TURN ON KAT500" is displayed. Previously this condition would lock up the K3 without explanation

Subject: [Elecraft] KPA500 - KAT500 stopping K3 boot

Is there an issue with the KPA500 being OFF with power up -> booting of the K3?  Does it need to be actually powered up, i.e. and in operational state?  OR is just having it in the ?sleeping? state (REAR switch ON, FRONT PANEL SW-OFF) OK?

I know about KAT500 and AUX-BUSS stopping K3 bootup, and have an ?automatic? solution that works great.

While running FT8 on my KX2/KXPA100, the TX red LED will sometimes stay on
and the FT8 waterfall shows blank (like when TXing). ALC is stuck on 1 Bar
when I've got it set 4-5 Bars. If I click Tune in WSJT-X once or twice I see
the 4-5 Bars ALC and then all returns to normal.

Is TX being "Stuck On" my KX2 or WSJT-X acting up? Using Win 10 and a

Hi

I had the same problem. I turned down the volume slider on the computer a little and the LED went out and the KX2 was in receive mode again.
I don't know why. Vox was turned off.

This was one of the problems I was having. Mostly on 40. I ended up putting
3 turns of the transmit audio line through a random snap on ferrite I
happened to have in the bag. The hangup stopped and alc settled down to a
stable value instead of jumping around.

I have followed the calibration procedure in the manual (WWV as I don?t have a frequency generator).  On 50 MHz, I am spot on.  However, on 2 meters, I am off by 1 KHz.

I have recently replaced the TCXO, so I don?t believe that is the cause. 

Any suggestions as to how I can get 2 meters to agree?

The problem here just came about on this temporary lication (temporary work
area), I have not had the problem before. There is not much space in the
yard area at the little apartment that I am living in for the summer. And I
just had this random bead laying in the bag with other odds and ends. I am
glad it was there though as it has kept me on the air.

Without a calibrated signal generator (or generator and calibrated
counter), how are you measuring this?

> Any suggestions as to how I can get 2 meters to agree?

To agree with what, and how do you know it's right?

It would help if you explained more precisely what you did.  I'm
guessing you used 15 MHz WWV, but then what are you doing on 50 and 144
MHz to measure?  Did you measure 28 MHz?  What are you measuring
against?  How is that calibrated, and how do you know it is correct?

(Also, I am unclear on how the 144 Mhz option works, but that's
important to understand.)

Thanks to all who sent advice ...? Don (as usual) steered me in the
right direction.

I need to replace the K1 relay as I accidentally touched it when
removing the RF Board C6 capacitor for the K60XV installation. Didn't
think much at the time, but definitely bit me in the tail here.

 From my take, the radio is in transmit mode, the ALC is showing 1 bar 
and stuck in transmit.? This to me says there is noise coming out of the 
computer, even though WSJT-X is given the receive command.?? Somewhere 
in this post I read that the OP reducing the computer slider eliminated 
the issue.?? This again says there is / was noise coming out of the 
computer causing the VOX in the interface, not the radio as the VOX was 
off, to be tripped by the computer noise.

There are multiple places where the audio level from the computer to the 
radio can and must be adjusted correctly.? From experience, none of the 
level adjustments should be at or near maximum and same for the minimum 
audio level adjustments.? Strive for a mid range value of all 
adjustments.??? The PWR slider on the WSJT-X screen is one of the 3 or 4 
audio level adjustments.

As to Elecraft ALC, it is clearly different in behavior and indication 
with regard to "other" radios. ? Do Not apply "other" radio methods for 
the Elecraft radios. ? ? For Elecraft radios, the ALC indicator, to 
which the first 4 bars are actually AUDIO LEVEL indication, thus are not 
indicating ALC action.? The ALC takes place at or after the 5th bar.?? 
For that reason, one should adjust the audio levels such that there are 
4 bars on solid and the 5th bar flickering on and off.? With the 5th bar 
flickering, set the power output using the PWR control on the radio {not 
on WSJT-X} and do not adjust any audio level.

In the case of the K3S and maybe other radios, I find when using the 
TUNE function from WSJT-X of 1500 Hz there seems to be a beat between 
the tone and the display scan rate.? This produces a wildly fluctuation 
in level appearance.? Change the TUNE tone to some value slightly higher 
or lower and the issue will be resolved.

While I had quite a few Mix31 beads on antenna coax and the various other
power, CAT and audio cables connecting my rig, it seems adding a few more
helped. I think it was a ferrite bead on the special cable set that connects
the KXPA100 and KX2 that did the trick. RF leaking in somehow!

While my base shack is all bonded to my AC panel ground, I'm running
"portable" with KX2/KPA100 on my deck and portable antennas in my back yard
while we're renovating. So I don't have a good bonding/ground configuration.
Virtually none!

Bret,

That sounds like noise, hum or buzz is getting into the audio cable 
between your soundcard and the KX2.  Try to find a metal connection on 
you soundcard and run a heavy guage wire between that point and the 
chassis of the KX2.  Run another between the soundcard and the computer. 
  Often that bonding will help by routing the noise along the bonding 
wire instead of the shield of the audio cable.

Also check for the possibility of RF feedback - if it works OK with a 
dummy load, the apply RF common mode chokes to the coax.

Mix #31 is useful on the HF bands ONLY if multiple turns are wound 
through the core.? Only passing the cable through a bead is useful only 
on 2M. Study k9yc.com/RFI-Ham.pdf? and http://k9yc.com/2018Cookbook.pdf

Every chassis in an interconnected system must be bonded together, even 
if there is no connection to the earth.? How are you powering the 
KX2/KPA100?? Battery? AC power supply and extension cord?

What is your antenna?? Is it some form of end-fed wire, vertical or 
random orientation? If so, you need some form of counterpoise to carry 
the antenna's return current. If you don't provide one, return current 
will flow on the coax to the radio and the other equipment connected to 
it, where it can cause mischief. And you need a common mode choke at the 
feedpoint (the far end of the coax) as described in the two links above.

Hi Don,

No metal on those USD Audio Adaptors, unfortunately. I tried some Audio
Isolator Transformers but those just gave PTT ERR on my KX2.

I see some USB and Ethernet Laptop Ground devices that the EMF-sensitive
people seem to use - I don't know if they work at all.

Bret,

There is no way that Audio Isolation transformers (by themselves) could 
produce an ERR PTT unless you have VOX turned ON and the transformers 
are making the hum worse.

ERR PTT means that there is a key (or PTT) closure during the power on 
sequence.  Look for the source.

I assume you have set PTT via CAT Command (or something similar) and 
have turned off VOX in the KX2.

Hanging in transmit can be caused by using two sources to turn on 
transmit.  Make sure there is nothing plugged into the KEY jack and the 
KXPD2 paddles are not closed - turn VOX to OFF and use PTT via CAT 
Command from the software for the most reliable PTT operation.

I apologize if this isn't applicable here. I don't have the KX2, so this 
may be useless. However, I had the same issue going on with FT8 and 
other digital modes with my KX3 (basically, anything the computer keyed. 
Mic keying worked correctly, however). Nothing seemed to fix it, even 
changing between computers, different sets of Elecraft cables, etc. With 
the KX3, I opened it up and pulled both ends of the ribbon cable between 
the top and bottom halves of the radio. When put back together, 
everything worked like I champ. I can't say why it worked, but it fixed 
my problem. Again, I don't know if the KX2 has this open half design 
like the KX3 since I don't have one. But, I thought I would throw this 
out in case it does.

Message-ID: <CADisrHk3bdyR9W+iGwb77W448qAdY8cpxtGvcWu4R3kcp5F0wQ@mail.gmail.com>

I would like to trade my ACOM1010 for an Elecraft KXPA w/ATU. The ACOM is
in essentially perfect condition; and currently wired for 120V. It would
sell used for more or less the same price as the KXPA w/ATU. If I'm buying
a used linear I'd sure rather arrange a trade (plus or minus) with someone
on this list than take my chances with eBay or other platforms. And of
course, if someone has a KXPA that they just don't have any use for, I'll
be more than glad to help them with it ;-).  I love my KX3, but I'm finding
that when operating portable, too often 10-15W is just not making the trip
these days; and the ACOM requires me to take a generator along. I would
also be glad to just sell the ACOM if you're interested but don't have a
KXPA to trade.

Thanks,

Message-ID: <3A84C0D8-D723-4044-8661-F3F3D4C56705@mac.com>

I am selling my Astron RS-50M Linear Power Supply but prefer to sell locally (Greater Seattle Area) rather than box up and ship it so prefer some kind of local pickup (or, delivery if not too far out of my way).

It is in perfect condition except for the meter back lights are burned out.  I have owned a number of these Astrons and for some reason this always happens.  My other Astron supply does not have lights in the meters either however I never do look at those meters so for me it was no big deal ? lights aren?t needed anyway to read the meter.   No dents or scratches on the cabinet that I know of ? in fact, I don?t think it has ever been moved once I put it in place about 8 years ago.

I also built a nice wooden table that the power supply sits upon.  It is designed to allow airflow underneath from underneath.  The table is sized to provide a height of the power supply underneath my table I use for operating.  This table is offered as a free gift to the buyer if they want it.

This power supply retails for something above $300 depending on where you buy it.  I am offering it at $150.  No dents or scratches on the panel that I know of.

If interested, let me know by e-mail.

My other Astron supply does not have lights in the meters either however I never do look at those meters so for me it was no big deal ? lights aren?t needed anyway to read the meter.   No dents or scratches on the cabinet that I know of ? in fact, I don?t think it has ever been moved once I put it in place about 8 years ago.

I have a pair of weighted knobs for a K3. One for VFO A & one for VFO B.  I believe these are CQDX.RU knobs.  They are steel, coated (black), with silver inserts.  The VFO A knob has a finger dimple.  Photos upon request.  $140 + shipping.  I take PayPal.

Low batteries can also prevent accurate ATU operation, in my experience.  The ATU will do the best it can but can?t find a good match.  Fresh batteries or a switch to external power will help.

Subject: [Elecraft] Dedicated FTx Rig
Message-ID: <c007255d-25fa-a80d-e901-dc22512102f5@cis-broadband.com>


I'm certain this is not an original idea, but I wonder if somebody will 
ever come out with a dedicated all-in-one notebook-sized portable rig 
for the FT-type digital modes.? I'm pretty new to FT8/4 but I find it 
interesting that when I'm operating it all I ever do with my K3 is turn 
it on and make band changes since everything else is done on my 
computer.? I wouldn't even need to do that much on the K3 if WSJT-X had 
a button to make band changes.

Possibly such a unit might look like:

1.? 12 volt operation (10 watts output) for portable use

2.? large enough screen to be practical

3.? running modified (mouseless) version of WSJT-X? to allow up/down 
arrow keys for:

 ? ? a.? band selection
 ??? b.? frequency change in 2 KHz increments
 ??? c.? mode selection
 ??? d.? contact selection from activity window
 ??? e.? TX1-TX6 sequence override
 ??? f.?? transmit enable/disable

4.? a button to momentarily press for log, press/hold to autolog

5.? USB port to run modified WSJT-X from flash drive for easy upgrade 
and log transfer

6.? internal antenna tuner (could be manual)

7.? etc.

Rigs dedicated to specific modes have never been very popular, but I 
suspect that FTx might change that and I suspect an integrated low power 
SDR version could end up being fairly inexpensive.? A side advantage is 
that audio levels would be preset in hardware and we'd see less 
overdrive situations.? ;)

Anybody know if there is already something like this out there?? I can 
find small inexpensive transceivers designed for FT8, but they still 
require a separate computer.

Just some ramblings on a rainy day ...

73,
Dave?? AB7E

WSJT-X does, in fact, provide a way to do band changes without touching the
radio.
There's a pull down menu on the main window just to the left of the
frequency.  Click the little down arrow on that box, select the band, and
the radio will follow. The Frequencies tab under Files..Settings menu must
be configured with the  frequencies you plan to use on each band.

Regarding the idea of a dedicated, all-in-one rig for FT modes, I suspect
the reason that such single-purpose radios have never caught on is that
radio and computer technology often evolve at different rates. For
instance, you might wind up in a couple years with a box that contains a
perfectly good radio, but is stuck with a computer that's not suitable for
digital mode flavor of the month.  Keeping them separate is far more
flexible,at the expense of some integration and configuration work.

Maybe there's a market for such a device...maybe not. I can't imagine there
would be enough demand to justify it, but then again, maybe that's why I'm
not in the ham radio manufacturing business :)

Subject: [Elecraft] Want to move to a KXPA100 w/ATU;
	ACOM 1010 for sale or trade
Message-ID: <CADisrHkr+GF4_Rur8xyfDkhh57sVtHe7c1H_biEPuOLiY5ad-Q@mail.gmail.com>

I'm offering for trade or sale an ACOM 1010 in perfect condition. My
portable operating has changed since I acquired the KX3 and I'd like to
acquire a KXPA100 w/ATU to go with the KX3 for portable use. I have an ACOM
1010 that is wired for 120V and will output 200-250W with the 15W input
from a KX3; or 600W from a 60W input. As much as I love the ACOM, my budget
won't let me have both linears. I'm offering the ACOM for $1200 plus
shipping and insurance. Or, if you'd like to up your QRO performance with a
solid, resilient, single-tube linear; and have a KXPA100 to offer in trade,
I'm open to offers.

I live in San Diego County, so if you're in SOCAL or southern AZ we can
probably save something on shipping. Shipping and insurance to the midwest
US is roughly $120.

Thanks,

Neither a low battery condition nor a bad feedline or connector will have
any bearing on the ATU.MD menu option.

You?d probably end up with a computer anyway (except perhaps for portable operations) to do all the functions other than the ones that WSJT handles. For example, I check propagation, point my antenna, receive cluster and RBN spots, maintain a log of tens of thousands of QSOs in various modes and keep track of award progress, upload QSO data to Clublog in real time, upload to LOTW after each session and update my log with results, receive WhatsApp messages, and more.
If you had an onboard computer, you would still end up dumping data to an external one on a regular basis anyway. I think the division of labor between a rig and external computer is just about right.
Now if you are backpacking and just making a few QSOs for fun, that?s another story.

Sorry, try again.  

There was a fellow on the Facebook KX2 group who described an WSJT setup consisting of a KX2, RPi3 and an iPad. Pretty slick and light weight and with a little repackaging could be an all-in-one.

Another way to connect the two worlds of computers and radio would be to 
add the radio to the computer as a card on the motherboard.? Or plug it 
into a USB port on a laptop like a flash drive.? It is not quite a 
dedicated machine to do one thing but you will be able to upgrade the 
two parts separately.? You have the advantage of the power of the 
computer you choose while the radio does not need to be that complex.

Good Evening,

 ?? The fire danger has been very low this year.? I don't think we ever 
entered a true dry season.? Today it rained like it was the middle of 
November.? In about two weeks the tree which supports my main antenna 
has to come down.? I told them to drop it early in the week so I can 
have time to restring it.? There aren't any other trees as tall as this 
one but I think the next one to the East should be OK.? It was close 
enough to this one so its branches have been suppressed along the West 
side.? That will make it much easier to shoot a line from the roof.? 
Propagation tomorrow will be pretty close to what is has been lately.? 
We have been brushed by a little solar wind with another stream due on 
the 11th.? I expect that to keep QSB fluttering away.

Please join us on:

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 ? 7047 kHz at 0000z Monday (5 PM PDT Sunday)

"Now if you are backpacking and just making a few QSOs for fun, that?s 
another story."

That was my hypothetical intent.  For vacation and portable operation, 
I'd probably be using a non-directive antenna, I'd settle for whatever 
propagation there was, I'd be making FAR less than tens of thousands of 
QSOs, and I already suggested transferring logs to my desktop computer 
via a USB flash drive.

The idea would be to avoid dragging along a computer and hassle with all 
the cabling.  There all kinds of folks here on this reflector using 
KX2's and KX3's interfaced with laptops and iPads for portable 
operation.  That just seems like a sloppy way to do it when a rather 
simple all-in-one unit with a much simpler radio could handle the same 
task less expensively.

SDR radios don't require the entanglement of cables and can be quite
portable. I have two - the mcHF and the older Apache Labs Anan-10e. Only
one ethernet cable connects them to a small laptop for any/all modes.
6-160m with the Anan; 10-80 with the mcHF.

Hopefully the KX4 will have this efficiency and easy-of-connectivity as
well.

I see a wonderful building project here. Lets start out with a 
Raspberry Pi -- for me the latest version with plenty of compute 
power for FT8 It draws about 2-3A @ 12V. Add in a HDMI display 
(from Adafruit) at about 0.8A @ 12V, some kind of sound card (if 
the display doesn't have sound), and a USB keyboard. (I would go 
with a separate keyboard for its typing advantages. YMMV) We now 
have a functioning computer.

The next question is what we do about a radio and here comes the 
camel's nose into the tent. The simplest solution is a 
single-mode, single-band dedicated radio. One of my favorite 
radios is the Small Wonders Labs PSK-20. (Unfortunately the kit 
is SK.) It tuned the PSK subband at 14.070 and nothing else. It 
had no UI, everything was done on the computer. It should be 
simple to retune it for 14.074 and run FT8.

But suppose we want more than that. There are any number of QRP 
radio kits around that might do. Or even a KX2. But the KX2 
wouldn't be enough for my friend Jim, K6EI who likes to go into 
the woods of Washington state and run QRP 160M. He'd need at 
least a KX3.

Regardless of what radio is chosen, it would be easy to leave 
enough space around the computer board to allow for future 
computer upgrades. (I assume the computer will become obsolete 
faster than the radio.)

Have fun building.

Michael,

Can we assume that this is a K3 or K3S?
If so, turn to the Calibration Procedures in the manual and do the 
Reference Oscillator calibration.  Use Method 2 (Zero Beating).

Since your radio seems to be WAY off, set CONFIG:REF CAL to 49,380 kHz 
first.

I have a pair of weighted knobs for a K3. One for VFO A & one for VFO B.  I
believe these are CQDX.RU knobs.  They are steel, coated (black), with
silver inserts.  The VFO A knob has a finger dimple.  Photos upon request.
$140 + shipping.  I take PayPal.

Low batteries can also prevent accurate ATU operation, in my experience.
The ATU will do the best it can but can?t find a good match.  Fresh
batteries or a switch to external power will help.

Subject: [Elecraft] Dedicated FTx Rig
Message-ID: <c007255d-25fa-a80d-e901-dc22512102f5 at cis-broadband.com>
Content-Type: text/plain; charset=utf-8; format=flowed


I'm certain this is not an original idea, but I wonder if somebody will 
ever come out with a dedicated all-in-one notebook-sized portable rig 
for the FT-type digital modes.? I'm pretty new to FT8/4 but I find it 
interesting that when I'm operating it all I ever do with my K3 is turn 
it on and make band changes since everything else is done on my 
computer.? I wouldn't even need to do that much on the K3 if WSJT-X had 
a button to make band changes.

Possibly such a unit might look like:

1.? 12 volt operation (10 watts output) for portable use

2.? large enough screen to be practical

3.? running modified (mouseless) version of WSJT-X? to allow up/down 
arrow keys for:

 ? ? a.? band selection
 ??? b.? frequency change in 2 KHz increments
 ??? c.? mode selection
 ??? d.? contact selection from activity window
 ??? e.? TX1-TX6 sequence override
 ??? f.?? transmit enable/disable

4.? a button to momentarily press for log, press/hold to autolog

5.? USB port to run modified WSJT-X from flash drive for easy upgrade 
and log transfer

6.? internal antenna tuner (could be manual)

7.? etc.

Rigs dedicated to specific modes have never been very popular, but I 
suspect that FTx might change that and I suspect an integrated low power 
SDR version could end up being fairly inexpensive.? A side advantage is 
that audio levels would be preset in hardware and we'd see less 
overdrive situations.? ;)

Anybody know if there is already something like this out there?? I can 
find small inexpensive transceivers designed for FT8, but they still 
require a separate computer.

Just some ramblings on a rainy day ...

73,
Dave?? AB7E

WSJT-X does, in fact, provide a way to do band changes without touching the
radio.
There's a pull down menu on the main window just to the left of the
frequency.  Click the little down arrow on that box, select the band, and
the radio will follow. The Frequencies tab under Files..Settings menu must
be configured with the  frequencies you plan to use on each band.

Regarding the idea of a dedicated, all-in-one rig for FT modes, I suspect
the reason that such single-purpose radios have never caught on is that
radio and computer technology often evolve at different rates. For
instance, you might wind up in a couple years with a box that contains a
perfectly good radio, but is stuck with a computer that's not suitable for
digital mode flavor of the month.  Keeping them separate is far more
flexible,at the expense of some integration and configuration work.

Maybe there's a market for such a device...maybe not. I can't imagine there
would be enough demand to justify it, but then again, maybe that's why I'm
not in the ham radio manufacturing business :)

	<CADisrHkr+GF4_Rur8xyfDkhh57sVtHe7c1H_biEPuOLiY5ad-Q at mail.gmail.com>
Content-Type: text/plain; charset="UTF-8"

I'm offering for trade or sale an ACOM 1010 in perfect condition. My
portable operating has changed since I acquired the KX3 and I'd like to
acquire a KXPA100 w/ATU to go with the KX3 for portable use. I have an ACOM
1010 that is wired for 120V and will output 200-250W with the 15W input
from a KX3; or 600W from a 60W input. As much as I love the ACOM, my budget
won't let me have both linears. I'm offering the ACOM for $1200 plus
shipping and insurance. Or, if you'd like to up your QRO performance with a
solid, resilient, single-tube linear; and have a KXPA100 to offer in trade,
I'm open to offers.

I live in San Diego County, so if you're in SOCAL or southern AZ we can
probably save something on shipping. Shipping and insurance to the midwest
US is roughly $120.

Thanks,

Neither a low battery condition nor a bad feedline or connector will have
any bearing on the ATU.MD menu option.

You?d probably end up with a computer anyway (except perhaps for portable
operations) to do all the functions other than the ones that WSJT handles.
For example, I check propagation, point my antenna, receive cluster and RBN
spots, maintain a log of tens of thousands of QSOs in various modes and keep
track of award progress, upload QSO data to Clublog in real time, upload to
LOTW after each session and update my log with results, receive WhatsApp
messages, and more.
If you had an onboard computer, you would still end up dumping data to an
external one on a regular basis anyway. I think the division of labor
between a rig and external computer is just about right.
Now if you are backpacking and just making a few QSOs for fun, that?s
another story.

Sorry, try again.  

There was a fellow on the Facebook KX2 group who described an WSJT setup
consisting of a KX2, RPi3 and an iPad. Pretty slick and light weight and
with a little repackaging could be an all-in-one.

Another way to connect the two worlds of computers and radio would be to 
add the radio to the computer as a card on the motherboard.? Or plug it 
into a USB port on a laptop like a flash drive.? It is not quite a 
dedicated machine to do one thing but you will be able to upgrade the 
two parts separately.? You have the advantage of the power of the 
computer you choose while the radio does not need to be that complex.

Good Evening,

 ?? The fire danger has been very low this year.? I don't think we ever 
entered a true dry season.? Today it rained like it was the middle of 
November.? In about two weeks the tree which supports my main antenna 
has to come down.? I told them to drop it early in the week so I can 
have time to restring it.? There aren't any other trees as tall as this 
one but I think the next one to the East should be OK.? It was close 
enough to this one so its branches have been suppressed along the West 
side.? That will make it much easier to shoot a line from the roof.? 
Propagation tomorrow will be pretty close to what is has been lately.? 
We have been brushed by a little solar wind with another stream due on 
the 11th.? I expect that to keep QSB fluttering away.

Please join us on:

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
 ? 7047 kHz at 0000z Monday (5 PM PDT Sunday)

 ?? 73,
 ????? Kevin. KD5ONS

"Now if you are backpacking and just making a few QSOs for fun, that?s 
another story."

That was my hypothetical intent.  For vacation and portable operation, 
I'd probably be using a non-directive antenna, I'd settle for whatever 
propagation there was, I'd be making FAR less than tens of thousands of 
QSOs, and I already suggested transferring logs to my desktop computer 
via a USB flash drive.

The idea would be to avoid dragging along a computer and hassle with all 
the cabling.  There all kinds of folks here on this reflector using 
KX2's and KX3's interfaced with laptops and iPads for portable 
operation.  That just seems like a sloppy way to do it when a rather 
simple all-in-one unit with a much simpler radio could handle the same 
task less expensively.

For example, I check propagation, point my antenna, receive cluster and RBN
spots, maintain a log of tens of thousands of QSOs in various modes and keep
track of award progress, upload QSO data to Clublog in real time, upload to
LOTW after each session and update my log with results, receive WhatsApp
messages, and more.

SDR radios don't require the entanglement of cables and can be quite
portable. I have two - the mcHF and the older Apache Labs Anan-10e. Only
one ethernet cable connects them to a small laptop for any/all modes.
6-160m with the Anan; 10-80 with the mcHF.

Hopefully the KX4 will have this efficiency and easy-of-connectivity as
well.

I see a wonderful building project here. Lets start out with a 
Raspberry Pi -- for me the latest version with plenty of compute 
power for FT8 It draws about 2-3A @ 12V. Add in a HDMI display 
(from Adafruit) at about 0.8A @ 12V, some kind of sound card (if 
the display doesn't have sound), and a USB keyboard. (I would go 
with a separate keyboard for its typing advantages. YMMV) We now 
have a functioning computer.

The next question is what we do about a radio and here comes the 
camel's nose into the tent. The simplest solution is a 
single-mode, single-band dedicated radio. One of my favorite 
radios is the Small Wonders Labs PSK-20. (Unfortunately the kit 
is SK.) It tuned the PSK subband at 14.070 and nothing else. It 
had no UI, everything was done on the computer. It should be 
simple to retune it for 14.074 and run FT8.

But suppose we want more than that. There are any number of QRP 
radio kits around that might do. Or even a KX2. But the KX2 
wouldn't be enough for my friend Jim, K6EI who likes to go into 
the woods of Washington state and run QRP 160M. He'd need at 
least a KX3.

Regardless of what radio is chosen, it would be easy to leave 
enough space around the computer board to allow for future 
computer upgrades. (I assume the computer will become obsolete 
faster than the radio.)

Have fun building.

For Sale is a brand-new MH4 mic, still wrapped and in the box.  If you have
the old MH2, you might want to upgrade to the MH4 as the MH2 is no longer
available and not supplied with the K3s.  Buy mine for $45, which includes
free Priority 2-day shipping.

It is still not tuning, and it just says 25.4:1.

Did you try an external power supply?  Did you check the BNC connection to
the ATU?

I would plug ?elecraft atu 25.4:1? into my favorite search engine and start
a decision tree.

In my experience 25.4:1 denotes an open or possibly shorted antenna connection or a failed SWR measurement circuit. What happens if you bypass the ATU and transmit (or tune) into a known load?  Do you get an expected SWR?

25.4:1 = No antenna found. Switch ports if you have the amp or check ALL connections in the antenna circuit. 

What have you ?CHANGED??

 Arron,

Take a look at this URL:   http://elecraft.365791.n2.nabble.com/KX3-tuner-getting-stuck-at-25-4-1-SWR-td7629357.html. Your solution to this problem may be as easy as this.

Aaron,

That SWR normally indicates an open or shorted antenna connection.  It 
is the maximum value the KX3 can display.
What happens if you tune into a dummy load with a known good coax jumper 
connecting the KX3 to the dummy load?

Don W3FPR

Our normal net control Eric WB9JNZ was unable to participate today as well as keeper of the list and relay station John N6JW. The propagation gods were not kind to us today and without Eric and John we able to stumble through the net and collect 15 check ins.  QSB and surprising short skip (at least here in Colorado) on 20 meters were our challenges today.  Our relay stations once again saved the day.  Thanks to those relay station noted below.

The Elecraft SSB Net meets on Sunday at 1800 UTC on or about 14.3035 MHz.   With propagation at a low point we employ several relay stations located around the continental USA to assist with check ins.  As conditions permit we take questions and comments after check ins.

Our regular net control Eric WB9JNZ Chicago, IL should be back behind the mic next week.  Make it a point to join us next week and see what conditions materialize.

First off, since when does WSJT-X not have a band change function?

Your idea is fun to think about, but you can get darn close with a 
Raspberry Pi hooked up to your K3 or KX3 or whatever, remote controlled 
from your smart phone via VNC.

Yeah, I had never noticed that button over to the far left.? My mistake.

And I've received probably a dozen similar suggestions on how to 
accomplish the same thing with multiple pieces of gear, which wasn't my 
thought at all.? I'm sorry I brought it up.

If someone needs a PSK 20 or 80 Jon, N8UL at CHARTER.NET told me last night he has both unbuilt kits.  He may be willing to part with them.  We were discussing the unbuilt kits we have stuck away in drawers and cupboards.

For Sale is my low-mileage K3s in excellent working and cosmetic condition.  No scratches.  This is my back-up K3s and it has spent most of its short life under a gray Rose Kopp custom felt radio cover.  I purchased this new (factory assembled) in late 2015 and all upgrades, including insertion and calibration of all ten filters, were factory installed, including the KPOD Power Mod.  This K3s is fully loaded (except no 2M) and contains the following:



?       KPA-3 100W upgrade



?       KAT3A ATU



?       KTCXO3-1 XCO



?       KBPF3A General Coverage Rx Module



?       KDVR3 Digital Voice Recorder



?       KRX3A 2nd Receiver



?       Filters ? 2.8KHz, 1500Hz, 700Hz, 400Hz, 200Hz ? identical filters in main and sub-receiver ? the 700Hz and 200Hz pairs are factory-matched 5-pole, while the rest are 8-pole filters



Comes with original manual and box.  Supplied MH2 hand mic is also included.   $3,295, plus shipping.

Skip,

They can create a bend in the shaft if the K3 is dropped to the desktop, 
such as when the bail is retracted.
I would advise anyone NOT to ship the K3 with those knobs mounted.

My experience is with the K2.  There were several that were shipped to 
me for repair with the knob installed - many of those had bent encoder 
shafts.  I was usually able to straighten the shaft, but that is a chore 
in trial and error.

73,

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

Let me add to this post....  Elecraft quality, products and engineering are fabulous.  Yes, I have been drinking the cool-aid for a decade.  Love the entire deal.  Tired of much of the other manufacturers over the years. Have had issues only resolved by selling.  YMMV.  Mine doesn't.

Now for Eric and Wayne to keep providing us new products!

Subject: [Elecraft] Fixing a Winlink express, no audio input from K3S problem
Message-ID: <02a601d551ee$6b3a8040$41af80c0$@verizon.net>

I have Winlink Express running quite happily on a laptop, talking to a K3S thru the K3S?s USB cable.  I configured Winlink Express on an older desktop, and it did not play with the same K3S - although the Winlink Express can (e.g., using VARA) transmit a signal; it ?hears? nothing.  The USB Codec Microphone, which is how the K3S?s audio shows up on the PC, has sound - I can ?listen? to it using the Windows ability to listen to a sound input device. But, none of the Winlink Express modems running on the desktop can hear any audio.

 

Oddly, FLDIGI works just fine on the laptop and the desktop.

 

Finally, after some more poking around, I got it to work.  The magic was to change the ?Allow apps to access your microphone? setting in the Sound settings page to On.  This setting appears in the ?Microphone privacy settings? and I completely ignored it for more than a couple days!

 

 

Go to Settings/Sound.

Message-ID: <CADENs28DsaJ8DwrzCiUCwq6T1p7Oiqtw4Gr3cRHDVTquXkGEpw@mail.gmail.com>

For some reason, I could not reply to the mail list.

The ATU on my KX3 is not tuning. When I hit the tune button I hear the
relays and the display shows an SWR of 25.4-1
Here is what I have done so far.
Under the menu, the ATU MD is set to Auto
I hooked the KX3 to a dummy load with a good piece of coax and it still
showed SWR of 25.4-1.
I opened the KX3 up, removed the batteries, removed the 2-meter
transverter, and removed the ATU. The cable from J1 to the BNC was well
connected at both ends.  Upon inspection, I could find no loose cables or
parts in the rest of the KX3.
I reassembled everything and I am still getting an SWR of 25.4-1 with the
dummy load.

Subject: [Elecraft] K3 - MixW interfacing
Message-ID: <CAFaaW6tQr4NLxg2Su3xDZH5nz5R9r+rWqkxs0inSZW_v3zohGg@mail.gmail.com>

So after having built a KX1 15 yrs ago, and 5 yrs ago acquiring a KX-3,
I've finally gotten a [used] K3.

I use MixW for logging (I no longer use it for digital modes, and haven't
upgraded it for years). I had interfaced my old ICOM 746PRO  and it worked
perfectly, entering the frequency into the log.  Now I can't get the K3 to
do it.

I'm using a Dell laptop running Windows XP. I've tried interfacing radio
and computer with a serial cable (yes, the old laptop actually has a serial
interface) and also with a serial to USB converter, with no joy.

A bit of Googling told me that folks have gotten the interface to work by
selecting Kenwood as the radio (in MixW) and then selecting Elecraft K2 as
the model. Still no luck. The latest is that in the Freq column, MixW
displays
-13677 and that doesn't change when I turn the big knob on the K3.

Any suggestions?

and 8 data bits, 1 stop bit?

The only time I have seen this SWR on my KX3 is when the internal batteries (eneloop) were partially discharged and the voltage was 8.5 vdc (tuning caused the voltage to drop to 8.2 vdc).  I noticed this when testing beta firmware for Elecraft to assess ATU behavior using different voltages  Have you tried connecting your KX3 to an external power supply that delivers 13.4 vdc and at least 2a? If this does not address the issue contact Elecraft support.

Aaron,

Your tests leave a couple questions - I could assume, but I would rather 
not - unsaid things often reveal problems.

Are you powering the KX3 from an external supply having at least a 13.8 
volt output?

After you connected the dummy load, did you do an ATU TUNE?

Is there any chance you could have had a static surge on the antenna 
coax that could have zapped the wattmeter diodes?

Email support at elecraft.com to see if they can give you some points to 
measure.

73,
Don W3FPR

I am using "Kenwood", then "All Kenwoods" as the radio, in Mix 3.x.

If that does not work, then you have a serial port issue with Windows... 
  I am using a "real" serial port.

Do you have any software on the laptop that communicates with the K3?  Download and install the K3 Utility from the Elecraft website to test the connection. You'll want it anyway for firmware updates and calibrations.

Thanks, Jim

Yes - and after posting my request, I fiddled around a bit more I actually
stumbled into getting it work with the plain old serial interface.  I've
written down the settings that seem to work for me:

Kenwood
Elecraft K2
Com1  38400
PTT Via CAT Command
AFSK in place of FSK
Data 8 bits
Parity None
Stop bits 1
RTS Always ON
DTR Always ON

Now that it's working I won't touch a thing!!

First depends on the version of FLFIGI.?? I use v4.0.5

With that I choose K3/KX3 Beta as the radio from the HamLib. 38400 baud, 
1 stop.?? I do not have DTR or DTS checked.? With my configuration I end 
up with COM 5.

All works great with these values.

Hi Folks,

In his posts here and in two or three that I have had with him off line, I think Aaron needs to have a chat with Elecraft support, as Grant suggested. He has taken all the steps suggested (and just now suggested again), with no joy. Maybe the KX3 needs to take a trip to CA.

Subject: [Elecraft] Loaded K3s - Price Reduced
Message-ID: <5169AE8BB5CC4CFAAA850A905D6FD769@DESKTOPFSUHCE9>

For Sale is my low-mileage K3s in excellent working and cosmetic condition.  No scratches.  This is my back-up K3s and it has spent most of its short life under a gray custom radio cover.  I purchased this new (factory assembled) in late 2015 and all upgrades, including insertion and calibration of all ten filters, were factory installed, including the KPOD Power Mod.  This K3s is fully loaded (has all options except no 2M) and contains the following:
  a..   KPA-3 100W PA upgrade 
  b..   KAT3A ATU 
  c..   KTCXO3-1 XCO 
  d..   KBPF3A General Coverage Rx Module 
  e..   KDVR3 Digital Voice Recorder 
  f..   KRX3A 2nd Receiver 
  g..   Filters ? 2.8KHz, 1500Hz, 700Hz, 400Hz, 200Hz ? identical filters in main and sub-receiver ? the 200Hz pair is factory-matched 5-pole, while all the rest are 8-pole filters (the 700 Hz filters are special order INRAD matched filters).
Comes with original manual and box.  No key, mic, plugs, or antennas supplied.   $2,895, plus shipping.

Message-ID: <CAFaaW6tOB-3aQmpz6hWbb8_HFQCsijmeY7=br=+3=k0XotWyBA@mail.gmail.com>

So a couple of days ago I posted tale of woe, trying to get my newly
acquired K3 to work with MixW - well, thanks to a few off line e-mails and
some stumbling around, I got that working. Ditto, got N1MM+ working great.

Next - how to get the K3 to play with my SteppIR vertical antenna
controller. Worked fine with my ICOM 746PRO, where I had both MixW and
SteppIR autotracking working fine with the radio.

So:  My computer is a Windows XP thing that I bought specifically because
it has an actual RS232 (9 pin) serial interface, so no need to struggle
with a serial to USB adapter.  I made up a Y cable to interconnect K3,
SteppIR controller and computer. Lots of Googling told me that the
connections to SteppIR controller should be only DTR and Gnd, so I made
sure that was how it was wired. Other posts point out that the CONFIG
AutoInf should be set to Auto1 (one post said it should be set to Norm, so
I tried it both ways). I even tried setting K3, SteppIR and computer to a
slower data rate (9600) in case the 38k rate was too fast. No joy. Did the
obvious newbie stuff like turning things on and off, plugging and
unplugging cables - still NG.

As I said, my logging program and N1MM are working just fine (one at a
time, of course), and I could live without having the SteppIR do
autotracking as I change bands/frequencies, but dagnabbit!!! it's the
principle of the thing!  I ought to be able to have everything working.

Any suggestions would be appreciated.

Does SteppIR support your outdated OS?  Talk to them to determine if there's an OS issue?

Actually, the preferred method is to use a regular "Y" cable and a cable for the SteppIR's "S26" cable schematic intended specifically for the K3.  It can be found in the Steppir groups.IO file section, or I can send it to you.

The StepIR controller learns the frequency the radio is using by 
reading the RS-232 interface between the computer and the radio. 
It does not need to send data on that interface, so don't 
connect the transmit data line to protect the devices. RS-232 
interfaces can have only one device capable of transmitting. Two 
devices transmitting can damage the devices.

My StepIR controller won't work with the 38.4K data rate so I 
run my computer, the K3, and the P3 at 19.2K. Since I have the 
upgraded card in my K3 that supports CAT and sound over the same 
USB interface, I have to set the speed on the P3, the computer, 
and the StepIR controller to 19.2K.

You will also need a program running on your computer which 
regularly polls the radio for frequency information. Most 
logging programs will do this, but you can set the K3 to 
automatically send that information at regular intervals if such 
a program isn't running. The manual warns that some programs 
can't handle the frequency information if they didn't ask for 
it, but none of the Mac programs I run have that problem.

I use the N6TV Serial Box to connect all the pieces together, 
but a Y cable which doesn't connect out output data line from 
the StepIR controller should also work. Joe, W4TV sent you a 
diagram for such a cable.

Joe,  you're right of course - and thank you. I have no clue why I typed
DTR!  Google sources did indeed say RXD (received data, pin 2) and that is
in fact how I wired the cable.  I guess I was looking at my hand drawn
schematic notes and my eyes got a little dyslexic.

Also, thanks to you and others for mentioning that pins 7 and 9 need to be
shorted (as shown in the schematic you sent).  I did that, and - voila!

Everything's working now - SteppIR, MixW, N1MM+.  (the latter programs one
at a time, or course).

Thanks, everyone.

Subject: [Elecraft] New K2 Build w/ Options
Message-ID: <1565888443325-0.post@n2.nabble.com>

Good afternoon. 

I just received a new K2 kit from Elecraft (#7899). It includes all
available options for the K2/100 (amp, audio filter, 60m, SSB, etc.).

I understand adding these components after the K2 is built will require a
bit of rework to be completed. Is this true if you are building the entire
kit, with accessories, from scratch? I noticed the rework boards are no
longer available and I want to be sure I eliminate as much rework as
possible (if possible).

In other words, are there any accessories / addons I should be installing at
the time of the K2 build -- or do I complete the base K2 first before moving
on.

Thanks!

James - W0CD

James,

The amount of "rework" is minimal.  There are ways to avoid doing as 
much component removal and changes, but I would not recommend that you 
do it on your initial kit build.

If you were to build a 2nd K2 (after installing the various options 
once), then I can see you reviewing the installation steps for the 
options and doing those things as you build the K2, but for the first 
time, build the base K2, do the alignment and test, and then add the 
options.

To help set your mind at ease, the components that you will need to 
remove for each of the options is as follows:
KPA100 -- none
K160RX -- none
KXV60  -- remove two capacitors
KAF2  -- remove two wires on the back of the control board
KNB2  -- change 3 resistors
KSB2  -- remove one capacitor

So IMHO, the "rework" is minimal.  Most of the work for installation of 
the options is adds to the RF Board.  For older K2s (below SN 3000), 
there is a bit more rework, but not for yours.

The hardest part of removing components from the boards is removing the 
solder from the holes.  You can even waste the component to be removed 
and pull the leads out one at a time.  Clean up the solder pads with 
solder wick, and if solder remains in the holes, heat the pad and push 
the solder out with a wooden toothpick so you can insert the new 
component or header.

When I built mine, I built the option kits first, which got me familiar 
the assembly manuals, then I built the main kit, including the various 
connectors for the options, some of which needed temporary jumpers, 
where I used pushon jumper thingies.? It also involved a lot of 
perusing, and cross-referencing, the manuals. Once the main radio was 
finished and tested, then I added (plugged in) the option boards, one at 
a time, testing everything as I went. It all worked spendidly.

The only parts that I needed to add to the main radio at the time I 
built it were the connectors for the options, which were included in the 
options kits,? and some temporary jumpers.

I have a new to me K2 SN in the 1200's that appears to have a flaky RF Gain
control.  The lightest of touch on the knob triggers what I think is AGC.
The receiver goes silent for a few seconds, longer with slow AGC.  Is it
the pot or is there something else I should be looking at?

If I need to replace the RF Gain pot, what other updates should I do while
I've got the panel off?

Thanks.

Glenn,

It does sound like the RF Gain pot has become scratchy - replace it, 
don't even bother with temporary fixes like cleaning stuff.

With that serial number, replace both the RF Gain pot and the AF Gain 
pot.  While you have the front panel board removed from the metalwork, I 
would recommend that you do the entire Alternate AF Gain Wiring Mod.  It 
involves all three boards, but no parts - only trace cuts and added wire.

The first thing you should check is dust on the control variable 
resistor. Using a different variable resistor will give you a quick answer.

I put my KAT500 on the bottom because it made cable management easier.? There are no coax cables hanging over the back of the KPA500 so no strain on the cables/jacks.? A secondary benefit is that the KPA500 vents are unobstructed so no spacing is required.??Ken?WA2LBI?LG G6?------ Original message------From: Kevin, N4TTDate: Thu, Aug 15, 2019 16:22To: Elecraft Reflector Reflector;Cc: Subject:Re: [Elecraft] Foot Extensions fro KAT500/KPA500Thanks Ed and Bill.

All the pots in the K2 are sealed - no way for either dust or cleaning 
fluids to get into the pot workings.

To substitute a different variable resistor, one would have to remove 
the pot from the board - may as well just change it.  Order a new one 
from Elecraft.

The SteppIR "S26" cable will result in a doubly loaded "serial in"
line (two drivers connected to the K2/K3/K3S RxD line resulting in
no data to the K2/K3/K3s) when used with a standard "all 9" DB9 Y
cable.

The schematic for the SteppIR "Y" cable that I provided to K2HYD is
also available in the SteppIR groups.io files section and works
directly with SteppIR controllers and the K2, K3, K3S without any
other cables.

BTW, your "FT947" cable is labeled incorrectly - it is FT847.

Aaron,

I sent you an off-list email.  There is no K2AKIT.  The K2PAKIT has 
replacement transistors for the base K2.  There are other transistors in 
that kit - 2 PN2222A transistors for use at Q11 and Q13, and a 1.5 ohm 
1/2 watt resistor for those K2s that still have a 1/4 watt resistor at 
R50.  There is also new mounting standoffs for Q7 and Q8 if needed.

I have two RemoteRigs from a SK estate that I'm selling to benefit W3LF's widow. The first one is the basic pair, with power supply, unterminated power cable, ethernet cable, and may have been partially hooked up at some point, or not. It's $350 plus $10 towards domestic shipping. The second pair appears brand new, never installed, and includes the wi-fi board with antenna, plus the other items that come with the rigs. It's $400 plus $10 towards domestic shipping. Both are in the original boxes and in excellent to new condition.

These do not have the Elecraft specific cables.

Please reply off-list if you are interested. I have pictures.

there any reason why I can't use a low profile IC socket for this part?
The reason I am building this one is to replace the old one in my K2.  The
old one died and I suspect it is the IC Max1406.

Dave,

With that IC running at the slow rate of 4800 baud, there should be no 
problem with using a socket for it.

If you also have the switch for the KBT2 option installed, there will be 
a tighter fit, but it should clear with a low profile socket.

It is also very easy to make plug-in equivalents of the rework modules. In
fact that?s where they started. And as said here, they will just contain
jumpers or a couple of components.

I was on a SOTA activation I wanted to record the summit reference number
in one of the message buttons. I would push the message button and then 1
it would go into record mode. I would hit the left paddle and a dit would
happen but when I would hit the right paddle I would get a dah-dit. This
would only happen in record mode. It was fine when not recording.

Good Evening,

needed to find a tool so went to the shed where they're stored.? Then my 
eyes wandered to the shelves of books. Three bankers boxes of my Analog 
collection came in the house with me.? I began reading science fiction 
from the 70s and 80s.? Today I worked my way through a story by George 
R. R. Martin from back when he wrote SF.? Haviland Tuf is an interesting 
character who learns ecosystem engineering.? If only Hollywood was 
interested in making movies instead of special effects.

 ?? The solar flux index remains below 70.? SpaceWeather.com has not 
mentioned any solar streams hitting the earth so I don't expect much 
difference in propagation from last week.? We must be getting close to 
the bottom of this cycle.? Maybe next year will see some improvement.

 ?? The large tree holding the center of my inverted V is due to be cut 
on Tuesday.? I'll drop the antenna and roll it up on Monday.? Hopefully 
the tree will fall well and not land on anything important.? Then I'll 
shoot a line through the next tree to the east and raise it up again.? 
As long as it is down I will inspect the connections and fix anything 
which needs it.? I should be able to raise it as high as it was before 
though there are more branches to avoid.? As long as I am at it I think 
I will build a spare cut for twenty meters and raise it too.

Subject: [Elecraft] K2 Front Panel Resistance Check Readings :(
Message-ID: <1566150514912-0.post@n2.nabble.com>

I'm running into a problem with the resistance checks for the K2 Front Panel
Board. Specifically, I'm getting 0 reading from J1(1) - J1(7) and J1(12) -
J1(14).

My readings:

PIN // Expected // Actual

U1(1)  //  25k-35k  //  29.4k (GOOD)
U1(2)  //  25k-35k  //  29.5k (GOOD)
U1(3)  //  40k-60k  //  50.4k (GOOD)
U1(4)  //  >50k  //  12.8M (GOOD)
U1(5)  //  15k-40k  //  24.6k (GOOD)
U1(6-11)  //  0  //  0 (GOOD)
U1(12)  //  9k-11k  //  9.8k (GOOD)
U1(13-40)  //  >50k  //  >50k (GOOD)

J1(1)  //  >1M  //  0 (*BAD*)
J1(2)  //  >1M  //  0 (*BAD*)
J1(3)  //  >1M  //  0 (*BAD*)
J1(4)  //  >1M  //  0 (*BAD*)
J1(5)  //  >1M  //  0 (*BAD*)
J1(6)  //  >50k  //  0 (*BAD*)
J1(7)  //  >1M  //  0 (*BAD*)
J1(8)  //  0  //  0 (GOOD)
J1(9)  //  >50k  //  26.9M (GOOD)
J1(10)  //  >50k  //  9.4M (GOOD)
J1(11)  //  >50k  //  22.5M (GOOD)
J1(12)  //  >50k  //  0 (*BAD*)
J1(13)  //  >50k  //  0 (*BAD*)
J1(14)  //  >50k  //  0 (*BAD*)
J1(15)  //  10k-60k  //  71.6k (*HIGH*)
J1(16)  //  25k-35k  //  28.5k (GOOD)
J1(17)  //  25k-35k  //  28.3k (GOOD)
J1(18)  //  15k-40k  //  23.7k (GOOD)
J1(19)  //  1.5k-3.5k  //  2.5k (GOOD)
J1(20)  //  0  //  0 (GOOD)

I did not install the SSB option yet as indicated in the manual.

For each J1 pin reading zero, I did conduct a continuity check between the
pin and other parts on the board based on the diagram in Appendix B. All
were successful. (Most were done between J1 pins and the empty rows holes to
the right of the NB button).

I feel like I'm missing something very simple. Look at the diagram, PINS 1-7
seem to work with voice functions (SSB). Should I expect to get values here
if the option isn't installed?

Thanks from a first timer...

W0CD
James

Just got a shiny new KXPA100.  

I?m using ?tight? integration with my KX3.  The one downside I?ve observed is that when PA Mode is On, the cursor display on the PX3 gets jerky and doesn?t follow well.  It isn?t terrible, just jerky.  I assume this is the result of the KXPA adding data load through the PX3.

Can anyone confirm for me if this is normal behavior, or if I should be looking elsewhere?

Thanks ..

James,

I would not worry about the reading at J1 pin 15, but the others 
indicate a problem.

I do not know of your soldering skills, but it would seem that your 
solder is bleeding over enough to contact the ground plane that 
surrounds the connector and other solder pads on the board.

If you have a solder blob on any of the pins, that could be the problem. 
  Use solder wick to remove excess solder on the entire front panel 
board and reflow the solder using only a minimal amount of solder.
See the soldering tutorial on the Elecraft website to tell you what a 
good solder connection looks like.

Grant,

Don?t know if it?s normal behavior but my setup is exactly like yours and the behavior is the same. Especially noticeable at a high tuning rate. I bought the KXPA100 from an individual but it had never been used, essentially new.

Don ?

Thanks.  That answers my question.  You?re right, it?s close enough if you?re tuning slowly, but if you try to tune quickly the PX3 cursor doesn?t follow so well.

Grant,

Something else I've noticed since getting the KXPA100 is the Select knob on
the PX3 gets flaky if it's turned too fast. It seems to work fine if you
turn it slowly. For instance when setting the Ref Level if the Select
control is turned very fast the display just jitters and doesn't change the
level. But when turned at a very slow rate the level changes appropriately.
I didn't notice this behavior before I put the KXPA in line.

You might try that and let me know what happens.

Thanks,
Don, K5DW

I fiddled with it a bit, and really didn?t notice any major changes in how the PX3 controls function.  Not that there aren?t any.

The simple solution is to simply set PA Mode: Off when generally tuning around.

Don,

Thanks. I see quite a few others on this board have had the same problems in
the past. I'm wondering if my multimeter is reading 0 ohms due to infinite
resistance. I'll take a look at my soldering and see what I find. I didn't
notice much during my previous look last night.

For reference:

Just out of curiosity, is the serial speed set to 38400?  Running slower would make a difference.

If the reading is actually zero - like when the leads are touched to 
each other, then that is zero ohms, an indication of a short.
OTOH, if the reading is blank or whatever your ohmmeter reads when the 
leads are attached to nothing, then that is an indication of infinite 
resistance or something very high - and that qualifies as greater then 
(> symbol) 100k ohms.

Should have searched on Nabble first.  Finally found some discussion of this PX3 cursor lag issue when running a KXPA100 back in 2017.

Elecraft apparently recognized it as a bug, and talked about a fix, but I guess nothing has been forthcoming.

Technician, know your tools! and know what the readings are telling you.

What are you seeing on your DMM display?  Many DMMs show a blank display 
for an infinite resistance, while others show a "+" and others show
"OL".

Look at your DMM display when the leads are separated.  That is infinite 
resistance.
If the display actually shows "0", (same as with the leads shorted 
together) then that is a short circuit (zero ohms) that needs to be 
investigated.

Good Evening,

 ?? Conditions lately have not been great.? QSB is constant which is an 
oxymoron.? The noise level is not very high but neither are the signal 
levels so it's a wash.? The sun continues its inactivity.

I was not able to get to last week's net report so we'll start with that.


 ? On 14050.5 kHz at 2200z?? August 11, 2019

K6XK - Roy - IA???? We exchanged information on our respective J-38s.

K4TO - Dave - KY? Was doing alright with a decent signal too.


 ? On 7047.5 kHz at 0000z??? August 12, 2019

K6PJV - Dale - CA? Told me he would be celebrating his mother's 100th 
birthday this week

W6JHB - Jim - CA?? Jim also told me he would be gone this week.


 ? On 14050.5 kHz at 2200z??? August 18, 2019

NO8V - John - MI?? Reported normal August weather for lower Michigan: 
hot and muggy.

AB9V - Mike - IN

K6XK - Roy - IA????? Reported perfect weather - 72 degrees in Iowa in 
August is pretty nice.

K0DTJ - Brian - CA?? Brian also said he would be gone next week


 ? On 7047.5 kHz at 0000z??? August 19, 2019

K0DTJ - Brian - CA??? Fog rolled in and the temperature dropped

WM5F - Dwight - ID


Now back to reading my cases of Analog SF from the 50s, 60s, 70s, and 
80s.? Spider Robinson, Joe Delaney, Jerry Pournelle, Joe Haldeman, 
Harlan Ellison, Isaac Azimov, P. J. Plauger, Tak Hallus, Roger Zelazny, 
and many, many more.? I don't think I have read these after I first got 
them.? Fun.

Until next week stay well,

 ?? 73,

Message-ID: <1566210185983-0.post@n2.nabble.com>

I'm using a KX2/KXPA100 at 40W on a Win10 laptop with WSJT-X 2.1.0 for FT8.
Antenna is a G5RV at 40ft with base ATU 150ft away. I've been advised
elsewhere that "Fake It" is a better choice than "Rig" for Split Mode:  "it
depends on what filter the radio has. Most are 2.4Khz (300-2700). If so you
would most likely need to be between around 600 to 2300. It also depends on
the skirts of the filter on where power will drop off and you can maybe have
harmonics. If you want to limit your transmit audio to 1500-2000 you may not
be able to find a clear place to transmit. If you have CAT control then fake
it automatically will adjust your transmit audio frequency to be in the
sweet spot of the filter."

I understand the KX2 filter is DSP Filtering?: ?50-4000 Hz, so am not sure
about using "Fake It" or "Rig" and would appreciate comment. Thanks!

Message-ID: <CAJ-xeHn+1kSLC-msgPEFb_PZyyc8sdWLXqb6cNR8UOHmO6n0DA@mail.gmail.com>

The long quote is not describing the difference between "Rig" and "Fake
It". It is describing the difference between "Rig" or "Fake It" (either
one) and "None". It is the difference between having some method to QSY the
radio between RX and TX (either "Rig" or "Fake It" can do that), and not
QSYing the radio between RX and TX.

The difference between "Rig" and "Fake It" is simply in how the radio is
QSYed. "Rig" uses the radio's Split capability to switch frequencies
between RX and TX. "Fake It" actually QSYs the main VFO between RX and TX.

The reason "Fake It" is suggested is due to the way WSJT-X verifies whether
the QSY has taken place. With some radios and some rig control methods,
WSJT-X takes so long to turn split on and off and verify split status that
it turns out that simply QSYing the main VFO is faster.

Try them both, and take special note of how long it takes from the
beginning of a transmit cycle until the rig actually starts transmitting.
If "Split" takes noticeably longer than "Fake It", then use "Fake It".

I'd suggest using RIG for SPLIT mode. This takes care of any issues of concern

Not sure about a review at DXE, but categorically anything cooked up by 
the late Jack Smith K8ZOA is an exceptional performer.? The CLifton 
ports that DXE has done have been well implemented so you can expect 
good results.

I've used the original Clifton version of the board in a number of 
projects and it's excellent.? The huge reverse isolation ensures that 
the LO of the SDR does not feed back into the rig.

Message-ID: <DD7F32C2-C428-4F40-86DE-80EB47B7DD90@gmail.com>

So it's normal, I guess, that every new user of a product ?rediscovers" some of its unique characteristics.  

I rediscovered the issue of the effects of the KXPA100 on PX3 cursor behavior, making it twitchy and jumpy.  Since there has been previous discussion of a fix that Elecraft chimed in on, but there?s been no fix, I assume it may be a hardware/processing limitation, either of the KX3 or PX3.

To ameliorate the issue, I?ve added PA Mode ON/OFF functions as macros in the PX3 (since it isn?t an issue when the PX3 doesn?t come along on an outing).  Saves digging into KX3 menus to change the PA status and is certainly quicker.

PA Mode ON:  MN146;MP001;MN255;PC080;
PA Mode OFF:  MN146;MP000;MN255;PC010;

(I change power settings as well, YMMV).

Still ? it would be nice if there were a way to solve the underlying problem without waiting for the KX4 :-)

Clark,

I have installed the original Z10000 buffer amp in several K2s.  They 
work very well.  The DXE version is prebuilt, and should simplify 
installation.
I see 3 reviews on the DXE website (but none for the K2), and they all 
show it as excellent and easy to install.

Don...

I got one of the original Clifton Lab boards and installed it in my K2 
[after you had serviced the unit]. Installation required a choice of 
pick off points: right after the first mixer, and somewhere else a bit 
more isolated [don't have the instructions before me]. I chose the 
first. It works very well although the LO leakage is significant and 
results in a pretty big birdie on the pan display. This is not really a 
problem. That said, do you have any experience with this item using the 
more isolated pick off? If so, does the isolated pick off eliminate the 
birdie from the display? Thanks for your comments.

Elecraft's website:
https://elecraft.com/products/copy-of-kx2-f_kx2-transceiver-assembled if you
are unfamiliar with the KX2.  I didn't get to use it too much but the KX2 is
so sweet and very easy to operate if you've had Elecraft equipment prior to
owning the KX2.  Even if you've never owned Elecraft equipment before, you
will learn this full featured QRP rig quickly and have a ball with it.  Talk
about a full station in your pocket; this is it!  This one has the internal
ATU, attached paddle, MH3 microphone and lots of extras I acquired which all
neatly fit in the carrying case.   With it comes a Buddipole Deluxe:

	WSJT-X
Message-ID: <000401d5571d$5daacb40$190061c0$@garlic.com>

Here is a use case question.. 

The radio is connected to a single antenna.

VFO A is tuned to 14.074 MHz and VFO B is tuned to 14.080.  

An audio data stream from the VFO A frequency is "connected" to an instance
of WSJT-X decoding FT8. 

A second, independent audio stream from the VFO B frequency is concurrently
"connected" to a second instance of WSJT-X decoding FT4.  

Both instances of WSJT-X decode their respective audio streams,
concurrently.

Starting a QSO in either instance of WSJT-X switches the transmitter to the
appropriate VFO for the duration of the QSO.

The audio stream for the instance of WSJT-X not in the QSO is interrupted
while the transmitter is operating.

 

Can a K4 support this use case or is a K4D required?

Can this use case be supported if each instance of WSJT-X is in a different
band?

I'm no expert by any stretch of the imagination, but it doesn't sound to 
me like that would be effective with any single rig, K4 or otherwise.

First off, as best I can tell you need to assign different rigs to the 
multiple instances of WSJT-X if run on the same computer.? I don't 
believe you can assign the same rig to two different instances unless 
you use two separate computers, and then you have the nasty problem of 
feuding CAT signals.? Please correct me if you have found that statement 
to be erroneous.

Secondly, you can't simultaneously transmit on both frequencies (unless 
you use Fox/Hound mode, which is an entirely different matter) and you 
can't receive on one frequency while transmitting on the other so you 
end up staggering your QSOs with no gain in effectiveness ... other than 
maybe quicker band switching than doing it manually.

It seems to me that to gain any benefit without using Fox/Hound you need 
two separate transmitters, of course fed through a passive combiner if 
using the same antenna.

Or what am I misunderstanding?

Dave, 

Will be interesting to hear official answer from Elecraft.

A competitor?s radio does exactly what Logan outlined. You would bring up two instances of WSJT-X. Only one can transmit at a time.

I think you need a K4D with the second ADC.  You?d have VFO A in left ear, VFO C in right ear. Two instances (installed in two separate folders) WSJT, one listening to left channel, other listening to right channel. 

But you have to keep up with which is transmitting. Once you start a ASO on VFO A you don?t touch VFO C. 

What?s to gain in this scenario?

Message-ID: <A6B11A9E-7DE0-4CA2-90E0-E1DA7FE7AA92@aol.com>

I will be using my new KX3 in place of my ailing K3S while the latter is en route to Elecraft for repairs.

In addition to running the KX3 barefoot, I would like to run it into my KPA500/KAT500.  Is there a good method, plug and play or otherwise, for (a) hooking the KX3 up to the amp while the K3S is away, and (b) sharing the amp between the two rigs once the K3S gets back from Watsonville?

I don?t think you need the second ADC since the two frequencies are only 6 kHz away from each other. Otherwise if you used two different ADCs you would then need two antennas.

Robert,

Yes, the alternate connection point will reduce the K2 LO strength.
Be aware that there are other causes for that center spike on the 
display, including soundcard and cabling inadequacies.  If those are the 
real issue for you, the LP-Pan forum is the best place for advice.

First there is a cable set from Elecraft that includes a cable with an RCA jack to provide the key-out line to the Amp key-line. And then route the RF via that appropriate cable and you are set. If you previously ?taught? your KAT500 about your antenna(s), you are set. You should get between 300 and 350 Watts out, depending on band. I had trouble getting reliable operation of KAT500 with only the KX3 output.  But once the K3S tuned up everything, KX3 worked well. 

If you don?t have the cable set, there is a ?key out? signal on the Acc2(3/32 jack on lower side closest to rear of side panel). Make your own adapter.

Subject: [Elecraft] K4 Use Case Question - Support for multiple
 instances of WSJT-X
In-Reply-To: <000401d5571d$5daacb40$190061c0$@garlic.com>

This will work with either a K4 or a K4D. The VFOs can be on the same or different bands. 

If the two receivers were on different bands, and you only had one antenna, you'd want to make VFO A the higher-frequency band. This is because with a single antenna, both receivers would be sharing the transmit signal path, which includes low-pass filters.

Suppose VFO A is on 20 meters and VFO B is on 40 meters. Both are subject to the 20 meter low-pass filter, so both will have full sensitivity. Now you want to work a station heard on 40 meters (VFO B/sub). Since you need the 40 meter low-pass filter for transmit, you'd the controlling computer would need to swap VFOs (or you could do this manually by tapping A/B). 

* * *

Notes:

- If you had a separate receiving antenna usable on multiple bands, then the low-pass filter constraint goes away; either VFO could be on any band. You'd still need to swap VFOs to transmit on the VFO B band, then swap back.

- If you had a K4D, then each receiver would have its own set of bandpass filters, which may be helpful in high-signal conditions. They could also use different antennas. 

- It may even be possible to run WSJT on the K4 itself, though I can't put a date on this. Some porting required :)

With the KX3 now aging from its 2012 debut, has anyone heard what might be on the
planning board for a KX4 ?   Inquiring minds . . . . .

If you are a KX3 user, what would you like to see?

Cheers,

I think you?re going to have to wait a bit for this one. The KX2 kinda slipped in there with a lot of bang fit the buck. And in a real small package.

Even a basic K4 can have the two receivers as far apart as you'd like, including on two different bands. 

The K4D (or a K4 with the KRX4 option added later on) gives you a second set of band-pass filters and the ability to use two different antennas.

Subject: [Elecraft] K3S, no line output on 1/8" jack
Message-ID: <CAPonRZ--tuRGUNsgZvGaNP=Si-taHomSra3rj6EffwBi4-WdtA@mail.gmail.com>

Hi,

I've been using my K3S for a few years now, and recently tried to record a
friends signal using the Line Out stereo 1/8" jack on the back of the rig.
However, there is no line level audio output on that jack.  Like many, I
use the USB interface for audio in/out when working digital modes, and
wonder if there is some conflict between USB audio and being able to get
Line Out audio on that back panel jack.

Any thoughts?

73, Bob, WB4SON

Yep. If you were looking for a sequel to the KX3, the answer appears
to have been:
smaller
lighter
capable of usage in an HT manner
lithium batteries
...and delivered as the KX2 :)

My KX3 is such a kickass radio, Its slow for me to think of upgrades not 
already done.
For some reason KX4 sounds wonderful. Maybe full vhf/uhf? Some of that K4 
tech?

I think I already want one!

With the KX3 now aging from its 2012 debut, has anyone heard what might be 
on the
planning board for a KX4 ?   Inquiring minds . . . . .

If you are a KX3 user, what would you like to see?

I would like to see a built-in sound card for digital modes.  As far as I know there is no small, portable rig that has this feature.  I do expect that a KX4 is either on the drawing boards or at least has been discussed by the Elecraft brain trust (aka Eric & Wayne).  73 de Carl

Subject: [Elecraft] K4 Use Case Question - Support for multiple
 instances of WSJT-X

Other than being able to monitor two different bands (or two different 
sections on the same band) I'm not sure what the benefit here is, but I 
wonder if I could accomplish the same thing with my K3.

1.? Run two instances of WSJT-X
2.? Use two different USB sound card dongles, each port assigned to one 
of the WSJT-X instances
3.? Use left ear/right ear audio output from the two K3 VFOs, left ear 
to one USB sound card and right ear to the other
4.? Use "Fake it" instead of "Rig" split control

I don't see that there's any gain in contact efficiency here, though.? 
The transmissions for two different QSOs would have to alternate, and 
the odds of getting out of sync with the guy on the other end would be 
significant.? If you were actually making a lot contacts from both VFOs 
this way you'd be disrupting a lot of sequences, and if everyone else 
was doing this it would be total chaos.

So I'll ask again ... what am I missing here?

73,
Dave? AB7E

Now you want to work a station heard on 40 meters (VFO B/sub). Since you need the 40 meter low-pass filter for transmit, you'd the controlling computer would need to swap VFOs (or you could do this manually by tapping A/B).

An upgrade to the kxbc3 to Li-ion or Li-poly would be great, but otherwise
my kx3 is pretty darn awesome.

This was my only disappointment with the KX3. They couldn?t find a low-noise USB chip, but the rat?s nest of cables still drives me nuts. I?ve probably spent as much on cables and USB audio devices and hubs as I would have spent on a more expensive KX3 with built-in USB.

What does the built in sound card buy you?? You don't save on cabling 
and USB sound card dongles for the computer are small, cheap, and work 
fine for digital modes.

Thanks for the explanation. The band pass filters add an interesting consideration to multi-band use.

Now you want to work a station heard on 40 meters (VFO B/sub). Since you need the 40 meter low-pass filter for transmit, you'd the controlling computer would need to swap VFOs (or you could do this manually by tapping A/B).

This was my only disappointment with the KX3. They couldn?t find a low-noise

The built-in sound card idea has been suggested, but I'd think you'd also need an accurate clock for the FT modes... perhaps via a GPS receiver.
Yes, the KX2 is smaller, lighter, etc... but the KX3 is not particularly large or heavy. ?So, maybe a KX4 would be about the same size as the KX3... or possibly a bit larger to accommodate some neat extra features. ?Nevertheless, I still like my KX3.

First, I don't intend to transmit on both VFO's at the same time.  I only have one transmitter.  But I do like having the ability to do an instant QSY.  Here are a couple of examples of how I use this capability. 

?Multi-tasking?.  You are chasing a goal: states, grid squares, thirteen colonies, Rt 66, etc. There is lots of activity on FT4 and FT8 and you don?t want to miss that tough one to find just because it was on the mode you weren?t using. So you switch back and forth as needed. 

?Picture in Picture?. There?s a DXpedition using FT4 on a non-standard frequency but the band isn?t open yet. So, you want to continue working states while you watch for the DXpedition.   This works particularly well with the digital modes because the decoding not only gives you call sign and location, but you can see how others are doing.  One DXpedition that I watched was running Fox/Hound and I could see lots of stations calling but there were no exchanges. 

I'm sure there are examples that others can suggest.

I think you need a K4D with the second ADC.  You?d have VFO A in left ear, VFO C in right ear. Two instances (installed in two separate folders) WSJT, one listening to left channel, other listening to right channel. 

But you have to keep up with which is transmitting. Once you start a ASO on VFO A you don?t touch VFO C. 

What?s to gain in this scenario?

Subject: [Elecraft] KPA500 Coax size requirements
Message-ID: <CAOWp2qZjxbTR13uyuVyuN3KKoHsh2ZSQbZL4VF9PkgoOZjnN2w@mail.gmail.com>

Hello friends,

I am contemplating buying a KPA500 amplifier/tuner Combo, and driving it
from my Elecraft K2/100 rig. I hope I would be able to do that!

 From what I have read on eHam Reviews, it appears that I can run the
amp/tuner combo on 117v. from the convenient wall socket. Is that correct,
as well?

I cannot find any mention of the coax requirements, from the radio/combo
out to our 80-meter wire loop antenna. Right now, using only my K2/100 I am
able to use  8X coax.

Will I still be able to use that coax cable with up to 500 Watts output?

What other considerations do I need to make?

Thanks in advance,

Carter Craigie, N3AO

Carter -

I run my KPA500 from the 120v outlet in my shack. I have done so for years
with no problems. I use LMR400 coax, but I know several folks who use RG8-X
with the KPA500, even on very long runs and some with amps putting out 1000
to 1500 watts. The better your antenna the less of a problem with that. If,
however, your antenna has a very high SWR without the use of the KAT500
tuner, then the tuner will make the rig happy, but there will still be SWR
loss on the coax, and it will be greater with RG8-X than with a larger and
lower loss coax.

Best of luck.

Carter:

The KAT500 can be {should be} powered from the radio 12V supply. ? I 
don't suggest a separate wall wart.

The KPA500 can be powered from either 120VAC or 240VAC, your choice.? It 
should drive on all bands with 20 to 30 watts output from the K2 to 
reach full 500 watts output from the amp.

As to coax, yes RG-8X is OK up to 30 MHz as long as the SWR is low.? The 
Belden Power rating is 1000 watts up to 10 MHz, 370 watts at 50 MHz.?? 
Loss is 0.9dB / 100 ft @ 10 MHz and 2.1 dB / 100 ft at 50 MHz.?? These 
power ratings are matched conditions.

What is the SWR on your wire loop on the feed line for all bands??? Per 
Belden, the UL voltage rating is 300 V RMS.? Thus 500 watts at 50 ohms, 
i.e. 1:1 SWR, is 158 volts.? However, 500 watts into 500 ohms, i.e. 10:1 
SWR, is 500 volts.? So to answer your question, YES and NO, depending on 
SWR on the coax between the tuner output and the loop antenna feed point.

In general, R-8X is OK at 500 watts below 30 MHz.?? From experience, it 
will get "warm" to the touch.? "Warm" is created by loss which is then 
heat generated from RF.? And that is RF which is not getting to the 
antenna.

Personally I'd opt for a balanced open wire feed to the loop and a very 
good 1:1 balun rated for legal limit or more at the KAT500 tuner output.

?The KAT500 can be {should be} powered from the radio 12V supply.?



Interested why this is true.  Can the KAT500 tell the difference between Elecraft 12V and Generic 12V?  Seems odd.



I ran two KAT500s on generic 12V from a DIN rail power supply for 5 years.  Necessary because the tuners and the amps were remoted in a closet 20 feet from the operating desk.  No problems.

Carter:

The KAT500 can be {should be} powered from the radio 12V supply.   I
don't suggest a separate wall wart.

The KPA500 can be powered from either 120VAC or 240VAC, your choice.  It
should drive on all bands with 20 to 30 watts output from the K2 to
reach full 500 watts output from the amp.

As to coax, yes RG-8X is OK up to 30 MHz as long as the SWR is low.  The
Belden Power rating is 1000 watts up to 10 MHz, 370 watts at 50 MHz.
Loss is 0.9dB / 100 ft @ 10 MHz and 2.1 dB / 100 ft at 50 MHz.   These
power ratings are matched conditions.

What is the SWR on your wire loop on the feed line for all bands?   Per
Belden, the UL voltage rating is 300 V RMS.  Thus 500 watts at 50 ohms,
i.e. 1:1 SWR, is 158 volts.  However, 500 watts into 500 ohms, i.e. 10:1
SWR, is 500 volts.  So to answer your question, YES and NO, depending on
SWR on the coax between the tuner output and the loop antenna feed point.

In general, R-8X is OK at 500 watts below 30 MHz.   From experience, it
will get "warm" to the touch.  "Warm" is created by loss which is then
heat generated from RF.  And that is RF which is not getting to the
antenna.

Personally I'd opt for a balanced open wire feed to the loop and a very
good 1:1 balun rated for legal limit or more at the KAT500 tuner output.

I think the issue is to be sure the tuner powers up with or after the K3.
But, mine turns on first and then the K3 later with no issues. I have pretuned it and run it on manual if that makes any difference.

I am pretty sure this dates back (literally years) to when the KAT500 first came out.
There was an issue if the KAT500 was not powered up before the K3, the K3 had problems during power on.
If the KAT500 was on a separate power supply many powered on the KAT500 before powering on the K3.
It was later discovered that the KAT500 only needed power to the coax power connector on the rear of the KAT500. The KAT500 did not actually need to be powered on. To this end it was advised that the K3 and KAT500 be powered from the same power supply.
All this went away in a K3 firmware update (version 4.9x. I don't remember which one) and has not been a problem since.
Since then the K3 and KAT500 can be powered from separate power supplies and the power supply connected to the KAT500 does not need to be on prior to powering on the K3.

Because in the manual, page 4, item 2 states "Connect to the station 11 
to 15 VDC power supply with the white striped lead to the positive 
terminal."

I view it best to always follow the manufactures instructions and not 
re-engineer the product or rewrite the manual.

Yes Bob the manual says that, but that statement in the manual was not revised after the 4.9x firmware update.
If you look at the manual revisions, that wording has been in the manual since the problem was initially discovered and before the 4.9x firmware update.

Yes Bob the manual says that, but that statement in the manual was not revised after the 4.9x firmware update.
If you look at the manual revisions, that wording has been in the manual since the problem was initially discovered and before the 4.9x firmware update.

Because in the manual, page 4, item 2 states "Connect to the station 11 to 15 VDC power supply with the white striped lead to the positive terminal."

I view it best to always follow the manufactures instructions and not re-engineer the product or rewrite the manual.

And since I have my KAT500 and KPA500 and K3S all on the desk within 
easy reach and view, and all interfaced with the ACC buss, thus keeping 
leads short and using one common supply makes lots of sense to me, and 
many less issues to deal with.

I've told many folks,? with the system as configured, I have a 500 watt 
transceiver and an antenna system that is effectively flat from 160M 
through 6M.?? All I do is change RX frequency on the K3S and every thing 
else follows.? No RF required to switch things to the correct 
configuration for band, frequency and antenna.

As to manual revisions, I see mine is C5, March 31, 2015.?? My KAT500 is 
s/n 1807 purchased? 7/21/18.?? I haven't kept up with paper revisions.?? 
However I have firmware 1.075 in the KAT500 and 5.67 in my K3S.? Looks 
like all of that is up to date.

LinOut is also on the USB cable. It would show as Audio CODEC on computer sound input devices. 

Usually, USB IN/OUT use will disable if the 1/8 jacks are used (according to manual).

RG-8X will be fine.  LMR-240 is also a good choice, a little less loss.

I picked up an 8-pack of these suction cup window candle holders from Amazon
for $7.99
https://www.amazon.com/Holiday-Joy-Strongest-Christmas-Celebration/dp/B01G6ED64K/ref=pd_lpo_sbs_201_t_0?_encoding=UTF8&psc=1&refRID=8QNVHSVD55PT9X9D610K

Three fit on the base tube of the AX1 antenna, clamp it tightly without
crushing, and hold the antenna to the outside of a hotel window with the
Elecraft tripod base and coax attached, as well as two counterpoise tossed
left and right.

Good to operate with KX2/3 or WSPRlite as I?m doing now. This particular
hotel has windows with metal trim and the antenna touches the trim to muck
up TX. Next trip I?ll have some silicone rubber tubing to insulate such
contact. Uber-light with AX1, 3 suction cups, tripod mount and 2
counterpoise, 10ft RG174 coax with Mix31 ferrite bead, WSPRlite, USB cable
and wall wart to AC mains. Fits in a baggie in a sneaker in my luggage.

See me on 20m WSPR at 200mW in FN20 through 8/22/19 in the AM if you can...

The part of operating the KX3 I like the least is switching 
between SSB and digital. I have to change the mic and headphones 
out and connect the sound card. On my K3, I just change the mode 
switch. Having an internal sound card would probably eliminate 
this hassle.

I like the KX2 form factor. For this kind of radio, small is 
good. It would be nice to support all the bands the KX3 supports 
-- 160, 6, and 2 meters. 160M support could be through a small 
external box, since pedestrian mobile on 160 doesn't seem 
likely. For ARES/RACES use, 70 cm would be needed.

The 110 Volt AC will be fine and draw 9 amps key down ? within a 15 amp
circuit breaker with plenty for more uses.  If VSWR is ok then RG-8X is
fine.  I have used LMR-240 as well but is intended for higher frequencies
up to UHF.

Have fun out there!

It is a shame to see folks go cheap on the cable. My rule of thumb is 
1dB or less between the rig and the antenna at the highest frequency of 
operation.

Warm coax is lost rf which we have paid heavily to generate.

Take a look at this coax loss calculator. It will tell you how much loss
there is in the coax, including extra loss due to SWR. You will have to
determine how much loss you can tolerate.

Losses in COAX is KEY DOWN CONDITIONS. 

ONE DB loss is the LEAST DETECTABLE amount a human can detect. Hardly if not impossible to notice.

The KPA500 runs on 120V or 240V.? The KAT500 runs on 11-15VDC. My two 
K3s (original model) run on a 100Ah Bionenne LiFePO4 battery, which 
stays above 13V for 90% of its charge capacity; the IMD (clicks, 
splatter) of a K3 increases with lower DC voltage, and lead acid 
batteries stay below 12V for most of their discharge curve.

The rest of the 12V gear in my shack, in addition shack lighting, runs 
on a 100Ah sealed lead acid battery. Both batteries are float-charged 
using Genasun charge regulators from spare Thinkpad power supplies. The 
Genasuns are MPPT chargers, so they step down the 20V from the power 
supplies to the battery voltage.

Has nothing to do with the amp -- study the ARRL Handbook and Antenna 
Book to learn these fundamentals. As others have mentioned, the major 
reason for using bigger coax is reduced loss, whether mismatched or not.

Someone suggested open wire or two-wire line with a balun at the tuner. 
That can transmit OK, but unless you're lucky enough to live in the 
middle of nowhere, that's a recipe for lots of receive noise. You can't 
work what you can't hear. The quietest antennas are resonant and 
reasonably well matched to the coax that feeds them, and with a serious 
common mode choke at the feedpoint (that is, up in the air).? Lots of 
specific advice atk9yc.com/publish.htm. Look for the HF choke cookbook, 
the RFI tutorial, and how to chase receive noise.

Not true. One dB IS approximately the smallest change in LOUDNESS that 
most listeners can hear, but what matters in radio is signal to noise 
ratio, and 1 dB can be the difference between making an not making a 
QSO. More important, losses throughout the signal chain add up. Losses 
also increase with mismatch.

> Hardly if not impossible to notice.

We notice these small things when signals are on the edge of being able 
to copy or not. Like when the DX station is trying to pull your weak 
signal out his noise.

Carter;

Welcome to the world of higher power. The information you have received from others is very good. There is one other thing to watch for, it is something that most hams who upgrade to higher power experience. When we operate at low power, there are a lot of things we can get away with such as relatively poor connectors, cheap coax and the like. When we add power, things change, and many of these things start having problems. Things like arcing across connectors (watch the elbows), whether at the antenna or along the path, heating of components (low-power baluns are especially bad), and many other things can give you fits. These will be noticed as faults, either in the ATU or the KPA, and make you wonder what is going on. 

The answer is to use good quality components in your antenna path from the ATU all the way to, and including the antenna. That will make the system, including the KAT and the KPA much happier, and with it, your use of it. 

As for the KPA500, it can indeed run at 120V quite well. Both of mine (which includes the first prototype) have run that way for many years. Both the KPA and the KAT monitor their environment extensively, and will report issues if they see any problems with the antenna system, usually in the form of high reflected power. Many hams use the units daily. We believe you will enjoy them as well!

If you have any questions, just ask!

Subject: [Elecraft] KX4 Features ??
Message-ID: <280920F7-4568-4082-823B-45D5C9110954@me.com>

I currently often use my KX2 with a QRPworks SideKar Plus and type on a 2.4 GHz qwerty keyboard.  My wishlist would include the ability to either plug in a USB keyboard or use a Bluetooth qwerty keyboard for text input directly to the radio.  Also, i would love a more versatile radio display which would be at least have the additional capability of displaying a single long horizontal scrolling [high resolution] line of text across the full width of the bottom edge of the radio display (instead of sequestering the VFO B display to reveal a whole seven characters of scrolling text)

I can think of a slew of other features; but bundling the functionality of the SideKar into the radio would be a wonderful thing

Cheers  es 73  de KX2CW  ..
~joan

P.S: i enjoy not dragging along a laptop for radio camping (although this habit currently limits me to the current suite of text modes bundled into the Elecraft firmware, i.e. PSK, FSK [RiTTY], and CW).  I wonder what other modes might be feasible to bundle into the radio?s own firmware.

That's not a universally true statement.

Several years ago I was trying to decide which antenna to buy, and my 
choice came down to two antennas that were 2 db apart.? I created some 
audio files by recording typical band noise and then overlaying them 
with recorded CW messages at various strengths.? The difference between 
1 dB above the noise level and 2 dB above the noise level can make the 
difference between no copy and copy.? The files and testing methodology 
can be found here:

http://www.ab7e.com/weak_signal/mdd.html

If you're ragchewing it doesn't matter, but if you're trying to make a 
contact and your signal is at the level of the mud it does.

Dave? AB7E

Speculation mode engaged.

For one thing, if a USB Hub functionality was also built in, you then
only need one physical USB connection between radio and computer, and
you could have full Rig Control, + USB Audio I/O, a well as the usual
KX3 utility functionality (firmware updates etc.)

Ideally, a galvanically isolated USB link to/from the outside world,
preventing ground loops.? Such devices are available, such as (but not
only) :- https://www.analog.com/en/products/ltm2884.html? (Not the
smallest of implementations, just referenced as an example of available
functionality, available now.)

No noisy micro SMPS needed either, as the rig already has it's own
internal power for the internal side, and the PC would power (via the
cable) the "external" side.

>From what I recall of the KX3 schematic, the Audio codec chip has plenty
of unused spare audio I/O lines, so at the very least, analogue Audio
I/O could (in principle) be possible with minimal changes to the
physical design (but not firmware I suspect.)? Easy for me to say that,
I don't have to do it.? But that alone would make an excellent rig even
better.

Many, many thanks to ALL of the Elecrafters who responded to my question

While it?s important to use quality components with high power for safety, its also important to use quality components especially to minimize losses with low power. Just sayin?

Yep. Our QRP operation for FD uses big coax.

Message-ID: <BYAPR16MB2968A706A39FC1BBBA80418C8CAA0@BYAPR16MB2968.namprd16.prod.outlook.com>

" All I do is change RX frequency on the K3S and every thing else follows.  No RF required to switch things to the correct configuration for band, frequency and antenna."

I think that having the KAT500 follow the K3 RX frequency is a really poor system design.  The tuner, and the tuner's frequency dependent antenna selection, should follow the transceiver transmit frequency.  Why does it matter? Well one day you will transmit with a large difference between TX and RX frequencies into the wrong antenna and with the wrong tuning solution.  This will fault the KAT500 and/or the KPA500 and could possibly cause damage.

It actually works a lot better if the KAT500 and KPA500 follow the rig TX frequency and are properly configured before the transmission starts.

Yes, I don't like the way the KAT500 follows RIT changes. Sometimes I 
cross a stored band slice boundary, the relays click and I know that if I 
transmit I'll be using the wrong tuning solution. I reported this as a bug 
back in 2014 [1] but I doubt it will ever get fixed.

Train the tuner at closer frequency intervals on the band and antenna.  I use 25kHz on 160M & 80M across the entire band.  Then 50kHz on all other bands.

Subject: [Elecraft] How much power can a KPA500 handle in bypass?
Message-ID: <037f01d55897$ea028f80$be07ae80$@videotron.ca>

HI,
I am setting up a multi-radio to  one antenna switch and to get the maximum
flexibility I would like to pass all of them through a KPA500 / KAT500
combination. So several radios connected to a switch, the output of the
switch to the input of the KPA500 and from there out to the KAT500.
All of the radios are under 100W but one is 200W.  Will this be an issue
with the KPA500 in bypass?
A related question, what if I accidently put the 200W in in operate?  Just
covering all my bases here.
Thanks, Tom

Well, if you overdrive it in operate mode it just drops out to standby. So
no problem there (I wouldn't make a habit of it though). As far as 200
watts in standby I will have to defer to the group.

According to the KPA500 Owner's Manual you can input 200 W in standby (page 16).

"A related question, what if I accidentally put the 200W in in operate? Just covering all my bases here."

Put some money away for the repair bill.  I think the theory is that that KPA500 will switch in 3 dB attenuation then fault and drop to bypass but I have seen a least one report of a KPA500 damaged with 100 W drive.  It's not worth the risk.

Design your station so the KPA500 cannot be keyed if transceiver power setting is more than about 40 W.  At that power input the 3 dB attenuator should protect the KPA500.

I just tried an experiment with a K3S and KPA1500, which uses the same
AUXBUS frequency mechanism as the KAT500. The KPA1500 has an LCD display of
the XCVR frequency, as sent by the K3S/K3 over AUXBUS. It comes in multiples
of 8 kHz.

 

I set VFOA to 14015 and VFO B to 14074.

 

When I turn on the transceiver (not in split), the KPA1500 reports the XCVR
frequency as 14008.

 

I then pressed (a "hold") the K3S SPLIT button, and the rig's LCD shows an
arrow to the VFO B frequency as the transmit VFO.  The KPA1500 reported that
the XCVR frequency changed to 14072.

 

Then I engaged XIT and dialed in 9.99 kHz.  When I turn XIT on and off, the
KPA1500 display alternates between 14072 and 14080.

 

The KAT500 owner's manual on page 16 says that the KAT500 can follow changes
in the K3's VFO frequency during receive. That means that you don't have to
transmit to get frequency information from the K3S/K3 to the KAT500/KPA1500,
the frequency information comes from the K3/K3s when it is receiving.  The
K3S/K3 can send the VFO frequency as it changes, by moving the transmit VFO
frequency with a knob (the VFO B knob when in split).  The frequency is sent
shortly after VFO encoder motion ceases. You need to turn on this capability
by a K3 menu, CONFIG:KAT3 and tap the 1 button to toggle between KAT500N and
KAT500Y.

 

Give it a try yourself. The KAT500 has a serial command "F;" that returns
the KAT500's last-known frequency, which comes from either AUXBUS or the
frequency count of the last transmission.

 

You can use the F setter from a computer program to set the KAT500's
frequency if you prefer. You should send the desired TX frequency.

Dick,

 

I can find no Elecraft specification for the data sent on AUXBUX but the
discussions on the reflector seem to consistently indicate the AUX BUS
frequency is the RX frequency not the TX frequency.  Can you please point me
to any Elecraft documentation that says the AUXBUS carries the TX frequency.

" All I do is change RX frequency on the K3S and every thing else follows.

I think that having the KAT500 follow the K3 RX frequency is a really poor
system design.  The tuner, and the tuner's frequency dependent antenna
selection, should follow the transceiver transmit frequency.  Why does it
matter? Well one day you will transmit with a large difference between TX
and RX frequencies into the wrong antenna and with the wrong tuning
solution.  This will fault the KAT500 and/or the KPA500 and could possibly
cause damage.

It actually works a lot better if the KAT500 and KPA500 follow the rig TX
frequency and are properly configured before the transmission starts.

Yeah, the group. We could take a vote. Or just ask Elecraft directly. This seems more of a tech support question to me.

The current version of the KAT500 manual is Rev C6 (3/8/17) and directs users
to connect the power cable to "the station 11 to 15 VDC power supply".  This
is another reason why we should use the most current manuals and update them
with firmware changes.  Elecraft is one of the few in this business who
allow adding notes to their PDF manuals.  Thank-you Elecraft!

BTW, more often than not what you read at e-ham is not correct.  It's often
someone's opinion which is not based on science or fact.  I would never
trust anything there without confirming the assertion with several other
sources.  Also, when others pile on with "Yes, that's correct." I will still
seek other sources.  98% of the time, you'll find the correct information in
this group.  Thank-you group!

The K4 will work with all K3 accessories:

   - MH4 microphone
   - SP3 (but we'll also be offering an SP4)
   - KPA500
   - KAT500
   - KPA1500
   - Kpod (connects to a USB port on the K4)

The K4HD uses the same style of crystal filters used in the K3, so it may be possible to reuse some of them. 

Transmit waveform monitoring is built-in for the K4 itself, and for any external amplifier that has a TX monitor output (like the KPA1500). 

Amps that don't have a TX monitor output will require an external signal tap. We may offer one, but I can't put a date on that yet.

Yes, I've found it there Bill, but not when I'm in the boonies with no cell
reception.  I always have one, usually more, computers with me.

Yes and the most issues I encounter in assisting other hams is that they 
DO NOT read the manuals.?? They take the approach "aw heck, I know how 
that works".?? Well that is just downright wrong.?? Look at the 
questions asked and issues presented and just how many of those are or 
can be answered by inducing the idea of RTFM.

Just because the firmware was updated and it is no longer required to 
have a correct power up sequence as stated in the outdated manual, I 
don't view this certainly doesn't make it wrong operationally.?? The 
later firmware just provided an option on power up sequence.

While on my soapbox, don't you just love it when someone asked a 
question or poses a problem, a solution is given, and they are never 
heard from again?? No thanks, no sharing the solution with others. ?? 
All take and no give.?? Seemingly the nature of society in general today.

It is really rather pathetic.

I believe accidentally hitting the KPA500 with 200 w while in operate
stands a real chance of damaging the KPA500. I have a broken KPA500 in the
shack that was damaged with a 100 watt rig (not sure if 100 watts was being
sent). Paper troubleshooting here on the list seems to indicate one of the
PIN switching diodes broke. History of the conversation should be in the
list archives.

Bill's (NR4C) feedback was the key, thank you!

My K3s was configured as LIN OUT=PHONES.  With that setting installing the
headphones would disable the Line Out jack on the back (perhaps thinking it
might be attached to some external audio processor).  Changing to LINE
OUT=nor 010 keeps the Line Out jack operational independent of the use of
the front panel PHONES jack.

I guess the behavior in LIN OUT=PHONES mode is not described explicitly on
page 22, 61, or 79/80 of the manual, which discusses the Line Out jack.  I
was impressed with all the extra hardware used for the Line Out jack (extra
24-bit DAC, audio amp, transformer, etc.).  Maybe a brief note on these
pages might help some future user.

Thanks again Bill!

73, Bob, WB4SON

Does anyone know what the CAT commands that allow you to switch from VFO A
to VFO B?

I have the phone section of a band set to VFO A,  and the CW section of that
band in VFO B.   I have the filters and mode set for each section of the
band.

Opps, sorry.  I was looking at the K3 table.

For the KX3 it would be SWT24;

I have my FTdx101D set to 50 watts max output. Been guilty of forgetting to turn it back to 20 watts a couple of times. So far been lucky. It seems to have survived 50 watts but it sure set the alarm off.

If setup according to the KAT500 manual (and using the appropriate cables), the 
KAT does follow the K3(S) TX frequency.

The tuner, and the tuner's frequency dependent antenna selection, should follow the transceiver transmit frequency.  Why does it matter? Well one day you will transmit with a large difference between TX and RX frequencies into the wrong antenna and with the wrong tuning solution.  This will fault the KAT500 and/or the KPA500 and could possibly cause damage.

"If setup according to the KAT500 manual (and using the appropriate cables), the KAT does follow the K3(S) TX frequency."

Thanks Wes, and to Dick for his earlier comments.   I'll assume from now on that anyone saying the KAT500 and KPA500 follow the RX frequency of a K3(S), when TX freq not equal to RX freq,  does not have the appropriate firmware or hardware configuration.

The documentation could be a lot clearer though.  For a rig that has two VFO and the ability to offset TX freq from RX freq by use of split, and/or RIT,  and/or XIT, saying the KAT500 will "follow changes in the K3?s VFO frequency during receive"  seems to be a somewhat inadequate description.

Well I must admit I learned something new and I was not correct in 
stating the KAT500 followed the RX frequency.?? I normally never have 
the RX and TX more than 1 kHz or less apart and rarely use RIT.?? Hence, 
when I change the RX I'm also changing the TX and the KAT500 follows.

I did confirm that VFO A was the RX VFO and activated SPLIT where VFO B 
was the TX VFO. ? With a frequency separation of 300 kHz on 80M between 
VFO A and VFO B, yes the KAT500 did change to follow VFO B.

Thanks guys.

I agree, Andy.? The manual should probably clearer about that.? Setting it up in 
the K3 when no KAT3 is installed is a little weird too, but it works out.

To check this out I used the KAT utility to watch the frequency that the KAT500 
was following. You do have to understand that the readout doesn't update until 
you stop turning the knob and it has only 8 kHz resolution.

My MFJ-223 VNA took a dive (cause unknown). The SWR readings are very high regardless of load. 

Has anyone found a schematic for this thing? The manual also mentions an MCU reset switch, but I'm guessing that's outdated. No such switch.

Message-ID: <B9C29CFC-2308-4CF4-A603-DDB4F9A24BCD@gmail.com>

My KX3, SN 3271, is completely dead on receive.  The transmitter, side tone and monitor control are working as ever.  Everything on the front screen seems the same as ever.  I don?t get any S meter reading when I inject the 50 microvolt 7040 KHz signal from my XG1.  Not sure if it is staying in the transmit mode with a transceiver switching problem, or just a problem with the receiver circuitry.  I can transmit with the KX3, and receive with my Collins 75A4.  I get 100 watts key down from my KXPA Amp.  I would like to use the fine receiver in my KX3, and would appreciate any comments.  While I only operate on CW, I listen to AM and SSB signals.  I can?t even here anything when tuned to a strong local AM station, using a wide filter.
Besides the KXBC3, my KX3 is equipped with the internal tuner.  
Extra Credit for answering the following; If I am not going to use internal batteries anymore, is there any problem with removing the cell holders and cable.  Can I also remove the KXBC3 board for possible resale?  Would I need to order a battery retainer if I am not using internal batteries? 
	
Thanks and 73,

I already did what they said they would do: open it up and look for any
parts that had come loose and resolder them. They don't build it and can't
do much in the way of troubleshooting. It's also out of warranty.l

I have no experience with that one, but a common failure of other small two
port VNAs is ESD blowing the RF switches at the ports. That is a one port
VNA, so I don't know if it even has switches.

What can it hurt to replace whatever part is closest to the connector?

I have a MiniVNA Tiny two port VNA and it works well, although dynamic
range could be better.

I have an MFJ 226 and it seems fine. But a friend had that one too and opted to get a Rig Expert analyzer to replace it because he liked it better. 
Might be a chance to try one if your MFJ is dead.

There is some pretty hilarious irony in that recommendation from MFJ.

That being said, is there any possibility to swap out the battery pack?? 
If it just gave up the ghost on it's own (i.e., you didn't accidentally 
blow the front end or something), that would be my first suspect for 
something that might just suddenly fail on it's own.

Dave?? AB7E

I recently installed the KAT2 tuner in my K2. I no longer need my T1.  The
T1 is lightly used.  Cosmetically and electrically I would rate it as a 10.
All documentation is with it. There is a new 9V battery in it, but I don't
think I can ship it per postal regulations.

$135 will get it shipped to you. No pay pal.  Check or money order is fine.

My direct email is MYCALL at ARRL  dot NET .  Actually all lower case.

Message-ID: <003901d559be$ff1ce640$fd56b2c0$@comcast.net>

I received a report of what seemed to be hot switching artifacts when
running QSK with my SPE 2K amp.  The K3S was set for the default TX Delay
but the friend who reported the issue later found an email from Wayne
indicating there was some issue with the default TX Delay of 8ms actually
being more like 5ms which would explain the issue.

 

I've not seen anything more about this and wonder if I've missed something
or Elecraft still working on it?

 

In the interim I've increased the value from 8ms to 11ms which should put it
in line with the actual 8ms default.

Message-ID: <CACp8OCj6T_2PFTQprdir53-A6EyO7qYmM+H148e0_yqF0vFtxQ@mail.gmail.com>

Hi everyone. I've decided to part with my KX3 -- in large part because the
City of New Orleans isn't especially amenable (elevation wise) for HF
operation, and my historic district makes erecting adequate antennas very
difficult. My radio was factory-built and includes many of the most
significant available options, including:

Internal 20-watt antenna tuner
Internal NiMH Charger with Real-Time Clock
Dual-Passband Roofing filter

It's been seldom-used (transmitting only on 10 meters as I still haven't
upgraded to General), and always indoors (no SOTA or similar ventures).

The radio also is mounted with the very slick, protective "ear" handles,
plus I'm including a Nifty! Ham Accessories Plexiglass stand that elevates
the radio and makes desktop operation considerably more comfortable.

Price: $1,000 + actual insured Priority or UPS shipping, via PayPal.

Please PM or email me for more information, and to see photos and the
original Elecraft invoice.

Thanks so much in advance, and best from NOLA,

Andy

I was recently considering a project which required to update my K2 with what is perhaps the last possible option ? the K60XV.

However, I was not able to find this product on the re-vamped Elecraft site. I did, however, find the newer K2 back panel that supports the jacks for the K60XV.

Did Elecraft discontinue this kit? Or can it still be special ordered?

I know there were some complications with firmware revisions in ordering the K60XV. My K2 is mostly up to date - I only need the firmware update for the KPA100, I think.

Bill,

As far as I know, there is no reason for the K60XV to have been 
discontinued.  Call the sales office to see if it can still be ordered.
You will need firmware version 2.04 to support the K60XV.  You can 
easily check your firmware revision level by holding any button in while 
powering on the K2 - the level for the MCU and the KIOC will be briefly 
displayed.

Don,

Actually, based on the shipping status (as of July 19th, 2019) K60XV
is marked as discontinued.

Don,

I was just told they were discontinued a couple of weeks ago. Not 
exactly sure why, but I assume one of the parts is no longer available. 
It is no longer on the order page.

 I am selling my K2 ser #7875 which has the SSB and KAF2 filter installed.
It has been fully tested by Elecraft and the test report will be included.
Reason for selling is wife will not allow any antennas. Price is 750.00
including shipping to any US address.

Get a loop antenna, stretch some strings across it, hang a feather in the middle and call it a Dreamcatcher.  Which it is!

Take up Summits on the Air and invite the wife to hike with you and watch you put up a temporary antenna attached to the K2 on a peak with a great view.

Everyone happy!

Sell the wife! Mine was reluctant at first, but I told her, what didn't you get... I had radio equipment on my apartment kitchen table when we were dating, I had been in the hobby since early teens and if  you think I am giving up this hobby, not going to happen!  She has slowly relented over the last 46 years.

Not much of a secondary market for wives.

Nice small portable rig calls for portable ops.

Just sayin'

OK Guys, let's tone it down.  These posts are bordering on inappropriate.

Message-ID: <CADENs29KUs05D6gHwv93ELbi+DvHt1BKDgzZd9ZafGY9TY7Atg@mail.gmail.com>

I was looking to purchase the K60XV 60 Meter option for my K2 this past
week and was informed by Elecraft Customer Support that it had been
discontinued, and I should ask around on this mail list to see if anyone
has one that they are willing to sell.
I am going to try to get the upgrades that I need while they are still
selling them.

I second the mag loop antenna or hidden antenna idea like they use in The Villages

https://www.k4vrc.com/uploads/1/0/1/5/10156032/present-tvarc_antenna_guide.pdf

and portable operation when the wife has other activities with her lady friends..... if Ham Radio is the hobby that puts a smile on your face (and in your heart) there are ?ways? to enjoy it.   If you give up this easily Ham Radio isn?t high on your list and I understand. I had radio before my wife came into the picture and she still complains about my wires in the back yard occasionally but I could complain about her buying scrap booking supplies but never using them or garage saleing buying more stuff that the grandkids don?t need or want ..... there are trade offs.  It has worked for 45 years. Just my not so humble opinion.

I haven?t tested it, but I recall that the delay is shortened if you use QRQ mode. With the K3S synthesizer, you really don?t need QRQ mode for reasonable hand sending speeds, so turn it off in the menu.

Thanks Vic.  I put in a query to Elecraft support about it and am awaiting their reply.

I may have accidentally put the K3S into QRQ mode but my 35 wpm sending hardly qualifies as that.

There used to be a problem with the K3 before the updated synthesizer came out; at just around 30 wpm the keying would start to sound erratic. But with the new synthesizer installed in a K3, or a K3S, there?s no problem at any speed I can send at, even with QRQ mode off.

Subject: [Elecraft] KPA-1500 Power Output Variation
Message-ID: <ed13ee39-ba13-7629-c5af-a9bbd0afd157@cox.net>

I'm using my K-3 with the KPA-1500 and have a problem with extreme 
changes in power output with a given drive level on 40m CW.? This 
happens to a lesser extent on other bands with different antennas.? My 
40m antenna is tuned to 7.025 where SWR is 1.1:1.? On 7.000 it is 1.4:1 
and at 7.050 it's 1.3:1. Within that range of frequencies the output 
_without_ the tuner at a given drive level (30w) varies from 1300w to 
well over 1700w.? Using careful _tuner_ settings it's only slightly 
better.? I have to reduce drive to 24 or 25w to get below 1500w, 
depending on the temperature of the amplifier (power output varies a lot 
with temperature changes).? Higher temp = lower output.

I have tried to compensate in the segments where output is excessive by 
using manual settings via the Utility.? This has helped slightly, but 
still isn't adequate.? I've resisted using ALC because of concern for 
generating distortion.? Having to ride the drive level from the K-3 is a 
PIA, especially during contests.

It seems to me a good answer would be to have higher input attenuation 
so drive requirement would be higher, maybe around 70+ watts.? I'd 
expect changing drive level by the same number of watts (5 or 6) would 
not affect output as much.? I'd also assume the power output would not 
vary nearly so much with a given drive level.

Is this a possible solution?? I've also understood that most 
transmitters (even the K-3) have cleaner output near highest rated output.

Help!

Seeing a 1.1:1.0 SWR at the amplifier doesn't necessarily mean your antenna is working as you expect.  Without getting into details, I am sure others will chime in, your antenna setup is highly suspicious given what you have briefly reported.  You didn't indicate antenna type, feedline, feedline distance, etc.  You might find reading an antenna handbook very informative.  You can also YouTube or do on line searches to learn about antenna matching.  As a KPA1500 owner, my antenna setup doesn't give me anything close to what you are experiencing.  Are you using the built in tuner?  Have you used an antenna analyzer to determine the antenna's characteristics on the frequencies you included in your questioning?

Antenna is 2 el. delta.? Uses 1/4 wave 70 ohm matching section. 
Described in ON4UN's Low Band DXing.? Used for 38 years with various 
tube amplifiers and no tuners.? All coax has been replaced as recently 
as 10 years ago.? SWR measurements always similar.? Power output with 
tube amps does not vary visibly on a Bird WM.? Same situation currently 
with a tube amp substituted.? Feedline from matching section about 50 
ft.? I know how to match antennas.:-) I have seen the usual reactance 
measurement on each side of design frequency of 7.025.? The built in 
tuner is the one I was referencing.? The KPA-1500 comes with one.

Jim,

It would be informative to know where you are observing the power variation.
In the feedline after the KAT1500 with your Bird WM or on the KPA1500 
panel display (or the KPA1500 Utility)?

I just did some experiments with my K3/KPA1500 combo into a dummy load.
I used my LP-700 for power measurements. Drive from K3 was set to 30W
(28 on K3 indication).

I started at 35C with PO at 1362 watts. At 70C, the PO dropped to 1277
watts...about a 6% decrease. K3 output remained steady at 30W.

What we need is someone with a separate tuner that can set up loads
greater and lesser than 50 Ohms and with Xc and Xl components. We may
find greater output with loads less than 50 Ohms and/or loads with Xl
rather than Xc. This is one of the disadvantages of having a fixed output
network. With the old AL-1200, I could just tune for max smoke and set
the drive accordingly!

Jim I don't have a KPA1500, but do have a KPA500. I'm not particularly surprised 
at your observations based on mine with the '500.

After a recent thread about amplifier efficiency I ran some tests on mine, using 
a well characterized dummy load and an LP-100A wattmeter, at rated output.? 
Although I only tested at the bottom of each band, I observed a variation in 
efficiency of a bit under 55% at 21 MHz to 75% at 3.5 MHz.? The gain varied from 
12.7 dB to 15.8 dB over the HF range (excluding 50 MHz)? Additionally, I see 
power jitter of several watts. In past two-tone IMD testing I've seen the 
spectrum break up due to (according to headquarters) the K3 ALC loop hunting.? 
As you no doubt have noticed adjusting output power by tweaking the input power 
isn't a smooth operation either. In short, this combination is anything but stable.

I believe that additional attenuation might be helpful if you can implement it 
without upsetting the RX path, although on most bands 2 or 3 dB extra 
attenuation wouldn't matter.

Thank you, Jim.  That is more helpful.  I use a remote tuner rather than using the built in for matching.  Thus my situation would not match yours.  I use a 350 loop on 40 meters, thus I would not be helpful in your situation.  Using a tube amp is much different in matching versus the solid state amplifier as I remember when I last used a tube amp.  I believe your specifics will now lead to a better answer to your situation.

Antenna is 2 el. delta.? Uses 1/4 wave 70 ohm matching section. 
Described in ON4UN's Low Band DXing.? Used for 38 years with various tube amplifiers and no tuners.? All coax has been replaced as recently as 10 years ago.? SWR measurements always similar.? Power output with tube amps does not vary visibly on a Bird WM.? Same situation currently with a tube amp substituted.? Feedline from matching section about 50 ft.? I know how to match antennas.:-) I have seen the usual reactance measurement on each side of design frequency of 7.025.? The built in tuner is the one I was referencing.? The KPA-1500 comes with one.

"I believe that additional attenuation might be helpful if you can implement it without upsetting the RX path, although on most bands 2 or 3 dB extra attenuation wouldn't matter."

Both the KPA500 and KPA1500 have built in drive attenuators (3 dB for KAT500, KPA1500 unknown) but there seems to be no serial command to activate them (only control is internal for over-drive protection).   It would seem to be a fairly simple firmware change to allow the user to activate the attenuator but that would remove a layer of protection from accidental over-drive.

Anyone willing to make a (minor?) hardware mod could activate the built in drive attenuator without impacting the RX signal path.

Like Wes, I'm not surprised he KPA1500 is sensitive to load.  I am surprised that sensitivity is still seen when the load is matched by the internal tuner.

Don,

I'm seeing the power changes on the front panel of the amp, on the 
Utility, and on the Bird external to the amplifier.? The Bird 2500w slug 
is about 40 years old, so it probably needs recalibrating.? Still, I can 
see the relative differences at all 3 spots.? There is no fault in the 
amp when it hits the high power level around 1700w.

My attenuator idea was to put it at the input of the transmit section of 
the amp, out of the receive line..... in the same place as the built in 
attenuator.? It still seems to me it would help for reasons I mentioned 
before.? With low drive levels the output is most sensitive to 
relatively small changes in drive.? I think the idea of running the K-3 
closer to rated output is still desirable.

Thanks, guys, for all the input.

Jim;

It would be interesting to see the source of the variance. You might insert the Bird between the transceiver and the KPA to see if there is any variance there.

The amplifier has fixed gain - it has no ability to vary its gain during transmission other than a protective pad that is inserted when problems are detected. The power is not
changing enough for that to be indicated, which makes me wonder just where the actual variance comes from.

73!

Jack,

Thanks for the idea.? I've not checked power in the drive line from the 
K-3.? However, when running the K-3 barefoot with the amp on or off at 
any power level I see none of these power changes in the K-3 output.

Other than my previous comment about drive levels, I have to wonder if 
it has to do with tuner firmware in the KPA-1500.? If nobody else is 
seeing a similar problem, there must be something before or after the 
amp that creates the problem.

The internal attenuator is only rated for short term usage in cases of over drive or high reflected power.  Any hw modification forcing it on will risk damage to the input attenuator components.

Eric,

If the attenuator had more attenuation that caused the drive to be 
closer to the K-3 output I would think this would reduce the sensitivity 
of the drive level with respect to change in power output.? 6w change in 
drive (from a larger input attenuator) from 80w would result in less 
output change (with the smaller attenuator) than with 6w change from 
30w. Is this right?

Jack,

When I change to the tube amp I use all the same cables and connectors 
for RF.? None of the problem occurs.? I have tried substituting cables.? 
I have not substituted the feedline of the 40m antenna, though.

Jim

Don?t know what happened to the list.  Keyboard models change so frequently it probably got to be a mess to keep up with it.

This Logitech is a Bluetooth keyboard.  Last I saw something about it, bluetooth wouldn?t work because it needed a PC BIOS to make the connection.

I use an Anker 2.4GHz wireless keyboard that works fine.  It comes with the wireless/USB adapter that stores in the keyboard battery compartment.  There are several types of these around.

I've had my KPA1500 for only a few months, and 99% of my operation has 
been on 6M. I also have an LP100A inline, calibrated at their factory. 
On 6M, with the tuner bypassed, The LP100A regularly reads about 100W 
(0.3 dB) lower than KPA1500 on keydown transmissions, and the LP100A 
reads about 1.8:1 SWR. The KPA1500 indicates 1.3:1 - 1.1:1 SWR 
(depending on the weather). If I engage the tuner, output power as read 
by the LP100A drops by 100W or so, indicating loss on the order of 0.3 
dB in the tuner.

How could this be? Simple. There are a relay, two UHF connector 
junctions, and 6-8 ft of RG400 (0.2 dB @ 50 MHz) between the LP100A and 
the output of the KPA1500. The connectors each contribute a bit of 
mismatch at 50 MHz, and the length of coax is transforming the load that 
the amp sees, so the LP100A and the KPA1500 are measuring both power and 
VSWR at different points.

Power accuracy of the LP100A is 5% (0.21 dB) worst case, 3% (0.13 dB) 
typical, and the power reading compensates for mismatch. It can read 
average, peak, and peak hold.

The point of all this is that, when you're trying to see small 
differences, there are a lot of little things that can add errors or 
make you think something is wrong when there isn't. :)

I got 2.4ghz Amazon Basics keyboard for it. I tried a wired keyboard, and
while it was a nice keyboard, RF kept getting into the keyboard buffer no
matter what I did. I tried toroids, chokes, you name it. It'd start shoving
spurious noise into the character stream, keeping it from finishing in PSK
or CW mode. When I switched to a 2.4ghz model, it works perfectly. Don't

Why worry about it?  No one on the other end would be able to tell one bit
of difference.  I see power drop -- maybe 5 - 10 percent -- as the KPA1500
heats up...likely normal.   The small bit of reflected power may also have
some minor effect on the wattmeter readings you see as well.  73, Greg-N4CC

That's not the point at all.? It's about having to ride the drive level 
control on the K-3 constantly, especially in a contest, to avoid sudden 
output of 1700w.

If you are into it, and want to avoid a full fledged keyboard, I have 
added an external keypad to my P3, and have 64 macros I can fire at a 
single button press...

Eric,

I have taken, perhaps obsessive, precautions to ensure that my KPA500 is not damaged by operator error.   I don't expect to ever trip the attenuator in my station.  However, I don't see anything in the documentation that imposes a limit on the amount of time that the KPA500 could be driven with power that trips the attenuator.

As an example - assume 30 W gives 500 W out and the antenna load is well matched.  Now I increase drive to 60 W.  The attenuator trips and the KPA500 is back to 30 W drive and a well matched load.  What causes the firmware to progress to a hard fault to protect the attenuator resistor?

Thanks and 73,
Andy, k3wyc

The internal attenuator is only rated for short term usage in cases of over drive or high reflected power.  Any hw modification forcing it on will risk damage to the input attenuator components.

Good Evening,

 ?? I got to watch a logger fall a very large tree exactly where he said 
it would land.? He laid it down between two long rows of trees with only 
a few live limbs broken.? After he left I got out my long tape and a 
shorter one just in case.? Laying down made it much easier to measure.? 
At 120 feet I wasn't sure which was one tree and which trunk was from 
another.? The stump measures 44 inches in diameter.? I limbed it up to 
about 80 feet before I tried bucking it.? Lower than that will take 
multiple cuts from my 20 inch saw to free each round.

 ?? My antenna tree had 60 very good years before it died a sudden 
death.? Each growth ring was between 1/4 and 3/8 of an inch in width 
until its last few years.? I have yet to find any damage consistent with 
its passing.? Now I have one very large chunk of wood blocking the deer 
paths.? If it is all seasoned it would heat the house for a full 
winter.? It's been dead for over two years but the lower part may still 
be a bit too green to burn.? Luckily there are plenty of other trees 
ready to go.

 ?? It took a few hours of placing and replacing a line but finally I 
got one which worked.? I checked the old antenna and found it intact so 
I raised it back into place.? One leg got tangled so I had to pull it, 
unwrap it, and the put it back into position.? While taking down both 
antennas I found better routes and replaced each of three legs higher 
than they were before.? The fourth leg went back to pretty much the same 
place as before. Scanning 80, 40, and 20 meters gathered a few calls 
around the US, a few in Canada, and few in Eastern Europe.


Please join us on:

Here?s a way to get a worst case estimate of the effect of SWR on power output. Assume the amplifier has constant VOLTAGE gain and an output impedance much smaller than 50 Ohms. A 1.3:1 SWR means the load impedance could be as low as 39 Ohms or as high as 65 Ohms. Let?s say the SWR is 1:1 at the frequency at which the drive is set for 1500 W output. Then you tune to where the SWR is 1.3:1. At that SWR, the output could be anything from 1150 to 1950 W. The range may be less, as the amplifier output impedance may not be all that low compared to 50 Ohms. In any case, this shows that the power output of a solid state amplifier may be very sensitive to load SWR.

This is why the KPA1500 ATU really needs to be able to keep the SWR low. The recently improved autotune firmware does this very well, if you ?train? it across the band. It is also why it?s important to use the ATU, even if the antenna SWR is ?only?, say, 1.5:1. 

I keep hoping Elecraft will come up with a way to automatically adjust drive power to maintain constant output. That would also compensate for change in temperature.

This happens to a lesser extent on other bands with different antennas.  My 40m antenna is tuned to 7.025 where SWR is 1.1:1.  On 7.000 it is 1.4:1 and at 7.050 it's 1.3:1. Within that range of frequencies the output _without_ the tuner at a given drive level (30w) varies from 1300w to well over 1700w.  Using careful _tuner_ settings it's only slightly better.  I have to reduce drive to 24 or 25w to get below 1500w, depending on the temperature of the amplifier (power output varies a lot with temperature changes).  Higher temp = lower output.

Has anyone actually used, observed, and measured the effect of the ALC 
feature of the amp in combination with the K3/K3S with regard to output 
power variation.

I do use the method and setup as suggested in the manual for both the 
KPA500 and K3S with no known ill effects. ? The amp drives to rated 
output with 20 watts on all bands. ? I find it never need more drive 
that this for 160M - 6M. ?? Output power variation with temperature is 
less than 10%? as measured over the range of? 23?C to 60?C.? Fan control 
is automatic and steps up and down as needed.

I do view if one hasn't used it, observed it or measured it, then "old 
opinions" of ALC implementation are not valid for comment.

As I've read earlier, likely an issue with the T/R switching diodes in 
the amp.?? Contact Tech Support at Elecraft.

Message-ID: <CAGK9h=Na60VS0-gC15of_wx3o9xz+vjhVRB_E6ds9fLd9Ux56A@mail.gmail.com>

Greetings, all.

I have a K3 with the KSYN3A synthesizers, K3EXREF external reference
option, and the K144XV internal 2-meter transverter. The K144XV also has
the internal PLL lock option board installed.

With this setup, I am trying to solve two problems: (1) knowing my 2-meter
frequency exactly, and (2) the 2-meter transverter drifts a lot when it
gets warm in MSK144 and FTx operation even though I'm running it at about 3
watts output.

The reference oscillator input SMA connector is connected to a surplus
Spectracom GPS-locked reference. All signs indicate that the K3EXREF is
working properly. In the REF CAL menu, the asterisk between the REF and CAL
is blinking at a 1-Hz rate. The radio seems to be right on frequency based
on some checks on the HF bands with known-frequency signals.

The transverter is configured as XV1. Its offset is configured for 3.8 kHz,
which is (approximately) the offset printed on the transverter for 144 MHz.
When I set the XV1 OFS to REFLOCK (using the 0 button on the keypad), the
XV1 OFS changes to 0.05 and the radio goes way off frequency from where it
should be. So it does not seem that the reference oscillator is locking the
K144XV's LO properly--although it's also possible that it's locked, but has
the incorrect offset. I can't tell because the menus don't have a display
option for the K144XV reference lock status.

I am sure that the cables are connected correctly based on the installation
documentation.

I've had spotty results with Elecraft support (not exactly poor, but
consistently slow and weak), so I wanted to reach out here to see if anyone
has experienced this issue and may be able to shed some light on what I am
seeing. Thanks in advance.

I agree with Bob.  This exact problem occurred with my KPA500 last year and
it was the switching diodes.  Support offered to send the parts for me to
replace but I opted to send the amp in for repair.  Support was a pleasure
to deal with.

Not necessary to guess - Page 17 of the KPA-1500 manual discusses ALC.? 
"ALC is a useful safety mechanism, but do not use ALC as the principle 
[sic] power control. ...Elecraft recommends using the K3 or K3s 
PWR-SET-PER-BAND function to set proper drive levels, not ALC.

Thanks for the suggestions to help with my ailing KX3.
I have tried them, and also a factory reset.  No joy.
Looks like the rig is not going into the receive mode.  The fact that injecting an S9 signal at 7040 KHz does not indicate on the S Meter makes me think the KX3  is staying in the transmit mode.
Looks like a trip to the Mothership is in the rigs future.

I don?t get any S meter reading when I inject the 50 microvolt 7040 KHz signal from my XG1.  Not sure if it is staying in the transmit mode with a transceiver switching problem, or just a problem with the receiver circuitry.

I recently got the KPA 1500 amp and guess I have some observations an
possible upgrades that maybe considered.
1.	I use my K3 and amp on all bands 160 thru 6 and have the internal 2
meter xfter using with a HB PQL LDMOS amp I built.  It uses RCA phone for
its PTT and the KPA 1500 is using the enhanced  cable. When I go from 6 to 2
meters the amp clicks and the freq indicates 5 MHz in the display.  If the
amp was in oper mode on 6 it then keys on when I tx on 2 meters.  Seems to
me it should recognize that it is on 2 and best case boot itself into
neutral.  
2.	I also would think a 1/2 speed of speed 1 would be a nicer starting
point.  I can handle 1 & 2 speeds but not totally used to it as the last amp
was quieter than this one. 
3.	On ssb and had TX Test mode selected so as not to TX.  When I hit
the paddle the amp goes TX mode and actually put out a little RF on the
LP100 meter.  Should not key amp in my thinking.
		
Hopefully I have entered this all correctly and am not booted off.  Thanks
for  any answers and thoughts.

I have K3 radios which have been updated with most K3S add-on's, including KIO3B, but I am not currently usingthe USB capability.? I use RS232 instead.
What am I missing that is worth making the change to USB?? I have the cables to do it, but the current configuration surely works.
I have a passing interest in digital modes FT4/FT8, but I have not gotten that function connected properly.
Would changing to USB eliminate any need for Line IN/OUT connections to solve the digi problem?
The current cabling is a mess.
I love these radios!

I'm not much of a phone op but my kx3 will not allow CMP setting in ssb
mode. When I tap the CMP button it says n/a. What do I have set incorrectly?

Thanks,

Good question.  Could you be HOLDING the button instead of just tapping it?  A HOLD (long press) on the button will take you to Pitch, which does return N/A.

Steve,

The USB connection will allow you to eliminate your external soundcard 
and the cables to the LINE IN/OUT jacks.
It will also eliminate any need for a USB to SERIAL adapter if you are 
currently using one.

You will need to use the CBLP3Y cable between the K3 and P3 instead of 
the RS-232 cables you are currently using - you said you have the 
cables, but just checking to be sure you have that "Y" cable.

So you end up with only the USB cable, and the "Y" cable between the K3 
and P3.

Your internal soundcard will identify as USB Audio CODEC, and the 
internal USB to serial adapter will be assigned a COM port number by 
your computer (much the same as a USB to Serial adapter would be).

73,
Don W3FPR

In-Reply-To: <CAGK9h=Na60VS0-gC15of_wx3o9xz+vjhVRB_E6ds9fLd9Ux56A@mail.gmail.com>
Message-ID: <CE64471D19DE47CD9CF55A1F2442AB02@N7IRDell9020>

Have you performed the modification to the KREF3 that increases its output level to compensate for the increased load of the K144RFLK board?

Search on the Elecraft web site for:  ?Elecraft KREF3 Output Level Modification? (pdf) 
Order KREF3MDKT (51 Ohm SMD 0603 size and 75 ohm 1/4 watt leaded resistors) 
https://ftp.elecraft.com/K3/Mod%20Notes%20Alerts/E740278%20KREF3%20Output%20Level%20Modification.pdf

Installing this modification solved a similar problem I was having with the K144XV, K144RFLK and K3EXREF when using them in a K3 that has a second receiver.  I have no drift now when running full power from the K144XV in MSK144 and FT8 to drive my old Mirage amplifier.

Another issue to be aware of is incorrect cable diagrams associated with the K144RFLK in some of the early documentation for installation of the KSYN3A synthesizers.  However, the radio will usually not work at all if the incorrect cable diagram is followed.  The correct diagram is contained in the following document.
https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740257%20KSYN3A%20Installation%20Rev%20A6.pdf

--------------------------------------------

Greetings, all. 

I have a K3 with the KSYN3A synthesizers, K3EXREF external reference option, and the K144XV internal 2-meter transverter. The K144XV also has the internal PLL lock option board installed.

With this setup, I am trying to solve two problems: (1) knowing my 2-meter frequency exactly, and (2) the 2-meter transverter drifts a lot when it gets warm in MSK144 and FTx operation even though I'm running it at about 3 watts output. 

The reference oscillator input SMA connector is connected to a surplus Spectracom GPS-locked reference. All signs indicate that the K3EXREF is working properly. In the REF CAL menu, the asterisk between the REF and CAL is blinking at a 1-Hz rate. The radio seems to be right on frequency based on some checks on the HF bands with known-frequency signals. 

The transverter is configured as XV1. Its offset is configured for 3.8 kHz, which is (approximately) the offset printed on the transverter for 144 MHz. When I set the XV1 OFS to REFLOCK (using the 0 button on the keypad), the XV1 OFS changes to 0.05 and the radio goes way off frequency from where it should be. So it does not seem that the reference oscillator is locking the K144XV's LO properly--although it's also possible that it's locked, but has the incorrect offset. I can't tell because the menus don't have a display option for the K144XV reference lock status. 

I am sure that the cables are connected correctly based on the installation documentation. 

I've had spotty results with Elecraft support (not exactly poor, but consistently slow and weak), so I wanted to reach out here to see if anyone has experienced this issue and may be able to shed some light on what I am seeing. Thanks in advance.

Actually, on the note of Bluetooth, and given the security issues announced
at Usenix Security conference in Santa Clara a week back....if Bluetooth is
supported, ensuring minimum entropy >1 byte would be a Good Thing.

Anyone?

That?s a real shame to hear.  I?ve been pretty happy with a K2 I bought
a few months ago as my first HF rig.  I recently came across one of the
6M transverters recently, which I felt was a good find.  Now, I realise
that having the KX60V might be nice to have.

If anyone has one sitting around the?re willing to sell, I?m game.

Message-ID: <52461013-d9ca-466d-6a11-4d48a2b3b532@ca.rr.com>

Hi All,

I have some work colleagues who need to test some HF components with a 
few hundred watts of CW power, perhaps a little more depending on what 
they find. I think this would mostly be in the 7 to 11 MHz range and 
perhaps at the 2nd and third harmonics of this range. Will my KPA500 
work for this? How about the KPA1500? What about the rest of the 1.8 to 
30 MHz range? Are there any excluded ranges in the coverage of these two 
amplifiers?

Thanks,

Mike W4EF......

As an owner of a KX2... IF there is something needed at all, then yes,
it would be the 70cm/2M option.
So far, the KX2 and any Anytone 878 do the job in combination.

The question is what is no longer obtainable to cause this. The K60XV as 
a unit isn't a complicated item. Component, metalwork?

Mike,

An email to support at elecraft.com will likely get you the best answer. 
It all depends on the filters in each amplifier.

I do know the bottom adjust trimmer capacitors are no longer available.
I cannot speak for any of the other components.

Mike
When you get a reply, please share.  I use a KPA500 with a KAT500 on Mars freq from 2-3.5 Mhz, 4-7.5 mhz
and 8.5 to 14Mhz. I have never noticed any problems but I have never checked anything other
does it work and stay within its operational numbers.

Another issue I wonder if someone has found an elegant solution to connect
or devices to the ACC connector as with the enhanced cable to the KPA 1500 I
need access to other ports.  We need a splitter/breakout device.

Bummer here. You snooze, you loose on as the K2 parts get harder to find.
My unit #6011 lacks the amp, NR module, and the KX60V. Hope to get a 160
antenna up this fall after adding the 160m module.

The K2, for me, is most enjoyable to use as well.

Greetings,

When I listen to my KX2 and KX3 using the Kenwood HS-5 headphones, I hear a square wave-like buzz bilaterally. Active signals can push the buzz into the background, but the buzz is annoying when there is no signal. Listening to the KX radios on another set of headphones does not produce the same buzz.

Using the HS-5  'phones on my K2 or TS-2000 results in very pleasant audio.

Anybody have any thoughts why this might be happening?

I built the N0SS amp keying circuit and just use my KPA500 and get around 350 out if needed.  Not to handy thou if you want to do some operating from a picnic table and battery power.  I too would like to get the amp as well and use the rig at field Day.

Bummer here. You snooze, you loose on as the K2 parts get harder to find.
My unit #6011 lacks the amp, NR module, and the KX60V. Hope to get a 160 antenna up this fall after adding the 160m module.

The K2, for me, is most enjoyable to use as well.

I have an early K3/100 [#642] and a P3.? On 60 m [5358.5] CW, I can see 
my signal when I key, at about -90 dBm on both the spectrum display and 
the waterfall.? This seems to occur only on 60 m, on other bands the P3 
display "mutes" on key-down. I just noticed it, don't know if it's 
always been that way or not.? Any ideas if this is a problem?

Here?s been a lot of discussion from time to time about compact lightweight speakers for portable operation with the KX3, and probably the KX2 also.

I?ve tried several things recommended here, and they?ve mostly all ended up in a storage bin in the garage awaiting their fate in a trash compactor ? sound awful, too flimsy, quit or broken after a week, whatever.  And I reverted to my old ?portable? Sony SRS-X33 that weights about 1.5 lbs.

I recently discovered the SoundMatters FOXL Dash 7.  Weighs less than 8 oz, 12 hour internal battery life, stereo, and sounds good.  Takes up no noticeable space in my (Rose Kopp) KX3 go bag.  This speaker was introduced around 2015, but is still available from the vendor (priced high) or from various eBay sellers for $90-95.  I bought mine from the manufacturer for $90, but they?ve since deleted that offer.  You can see mine in the top pic of my QRZ page.

Just an FYI ? in case you?re still hunting for something useful that won?t hurt your ears.  Pricey compared to some, but I?ve concluded you get what you pay for.

I brought along a NanoVNA this trip and used it to array the two counterpoise
attached to my AX1 antenna - adjustments of counterpoise brought SWR down
from 9+ to <2. SNRs in the low ?teens with a 200mW WSPRlite vs upper 20s -
*inside* a hotel room with sealed windows.

As Wayne said, the AX1 is particular wrt configuration. When it?s good, it?s
very, very good, but when it?s bad, it?s terrible. The NanoVNA is pretty
cheap/light kit to add if you?re not bringing an ATU-enabled rig.

This feature is already built in to the K3 / KPA500 or KPA1500 combo, but
not well known.

   1. While on 2m, go to the CONFIG:DIGOUT1 menu of the K3, set set DIGOUT1
   ON.  This drives ACC Pin 11 low when you are on 2m.
   2. This setting is per band and per antenna, so make sure DIGOUT1 is set
   to OFF on all other bands / antennas.
   3. Go to the KPA1500 menu TECH MODE and make it ENBALED
   4. Go to the KPA1500 menu TX INHIBIT and set it to ENABLED.  Pin 11 on
   the amplifier end is the Inhibit pin.

Per the KPA1500 manual, "When enabled and the INHIBIT line is pulled down,
the PA stage is bypassed. The MODE LED will remain in OPER.".

I just tested this an it works perfectly.  If DIGOUT1 is ON, and TX INHIBIT
ENABLED in the amp., the amp. does not KEY even though it remains in OPER
mode.  As soon as you set DIGOUT1 OFF (which will happen automatically on
other a bands), the amp. is keyed normally.  Please try this.

3.      On ssb and had TX Test mode selected so as not to TX.  When I hit

TX TEST mode has always closed the relay and keying lines even though the
rig is putting out no RF.  This is a safe way to test your keying relay
connections and amp. keying light, and perhaps it also protects the
receiver from getting a bunch of internal noise from inside the radio, so
that is working as designed.  Any RF you see could be caused by some static
when the amp relay is keyed, nothing more.  The K3 puts out no power when
in TX TEST mode, even if you have CW in SSB enabled and tap the key (which
you probably did at some point by going to CONFIG: CW WGHT and tapping [1]
to enabled it, which is useful in VHF bands it seems.  You can disable the
feature if you don't want RF to come out or don't want the relay to close
while you're in SSB mode and accidentally tap the paddle.

Hi Randy,

Yes, that's exactly what I designed the Y-BOX <https://bit.ly/Y-BOX> to
do, and it is still in production.

In addition to an Elecraft amplifier, lots of folks want to connect other
devices to the K3 ACC port at the same time, such as automatic band
decoders and antenna switches, FSK digital keyers, SO2R boxes, RemoteRig
boxes, etc.  You can try to use 15-pin Y-cables with all wires connected,
but they create a lot of clutter behind the radio, and proper Y-cables are
hard to find (most are made for VGA monitors, so they omit the VGA +5V
line, Pin 9, but that is one of the critical Elecraft Band Data pins).

The "breakout box" feature of the Y-BOX makes it easy to connect other
devices to the AUX port pins using simple RCA connectors, such as some FSK
Keyers (Mortty or WinKey v3), the SteppIR Tuning Relay Interrupt cable, or
a second footswitch.

The Y-BOX Version 2 ads a dedicated "AMP AUX" connector, with only selected
pins wired, wired exclusively for the Elecraft KPA500 / KAT500 / KPA1500.
The Elecraft KPAK3AUX cable set is *not* needed if you use the Y-BOX,
though it will work fine too.  But connect any stock $10 - $12 15-pin cable
to that port, and it works the same, plus it provides one more feature not
supported by the Elecraft AUX cable.  (Reminder:  VGA monitor cables must
*never* be used, with or without the Y-BOX, because they short too many
pins together.)

The Y-BOX v2 adds two internal jumpers.  One jumper allows you to power on
or off an attached KPA500 or KPA1500 using a K3 macro.  This feature is not
supported by the Elecraft cables unless you modify them. This uses DIGOUT1
Pin 11 on the K3 side and PWR ON Pin 8 on the amplifier side.

The other Y-BOX jumper can be used to open the keying line in the 15-pin
cable (Pin 10), which is what you must do when using any of the SteppIR or
N8LP Tuning Relay Interrupt safety devices to prevent high power from
damaging the antenna while it is tuning.  Normally you would have to attach
the male/male "tuning relay interrupt" adapter supplied with the KPAK3AUX
cable set to the back of the K3 to open the keying line in the 15-pin AUX
cable, otherwise the tuning relay interrupt won't work and you can damage
the antenna.  Using a Y-BOX and a simple stereo cable, the Tuning Relay
Interrupt is inserted in series with the keying line in the AUX cable, so
you only need one 15-pin cable to the amplifier.  Separate RCA phono
"Relay" between the amp, SteppIR Controller, and radio is not needed.

FYI, I can provide another box called The Serial Box <https://bit.ly/S-BOX>
(S-BOX and S-BOX-USB) which provides rig control and simultaneous amplifier
frequency tracking, plus computer-generated CW / PTT keying for a KX2 or
KX3 using a single USB cable (equivalent to setting CONFIG:PTT-KEY to
RTS-DTR in the K3, which is not an option on the KX2 or KX3).   It also
works with most non-Elecraft rigs and amplifiers, SteppIR controllers,
Kessler AT Autotuner, etc.

Finally, connecting a KPA500 or KPA1500 to a FlexRadio is now fully
supported via the S-BOX-USB V2, though I haven't updated my web site with
the details yet.

Obviously, a lot of us are dumping our K3's (plural) & K3S' (also plural) as their prices have fallen through the floor with the introduction of the K4.
(Can't say I'm thrilled about THAT, but it IS inevitable as new models are introduced.)

However, a lot of the 'for sale' listings cleverly try to sneak the "S" onto the model number, or imply that it is a K3S when the radio really is NOT a K3S.
Bear in mind, if your radio does not show K3S on the front panel, it is a K3, albeit upgraded, but  NOT a K3S.

The new synthesizer boards will improve performance, but there are some subtle differences between a K3 and a K3S that no amount of updating with new boards or mods can change. 

While the K3 concept of buying a newer "upgraded" synthesizer board for example,  rather than a new radio sounds like a great idea which will surely change the performance, I feel it is NOT a feasible solution, as it generates a worthless board that is only good as a pistol target.
My particular course of action was to sell my K3 after I had taken out what ever options I could add to a new K3S.  
That way, I get the latest production changes (note, there ARE a number of them pertinent ONLY to the K3S) and,  no junk boards are generated. 

Too bad I can't do the same thing with the K4.

One thought, have you run the Elecraft TX GAIN Calibration procedure
recently?  It's built in to the K3 Utility.

Unfortunately, the Utility sets the TX gain at a midpoint frequency on
every band, frequencies I rarely use, and I was observing first dit "power
spikes" in the output of the KPA1500 when driven by a K3.

To eliminate these power spikes (thanks to Rene at Elecraft for this tip),
with the amp. in STBY and the tuner enabled for best match on your favorite
frequency (or if connected to a dummy load), set the drive power to exactly
50W and press and hold the XMIT button (TUNE), then once the display
stabilizes, tap it again (just takes a few seconds).  This re-calibrates
the TX GAIN on that frequency, instead of the one used by the Utility.  At
any other power setting other than 50W, the TUNE button doesn't change
anything, so change the power level back after you are done.

You could do this once on you favorite areas of the CW bands, then use the
K3 Utility to Save that configuration, then repeat the procedure on the
phone segments, and use the K3 Utility to Restore whatever configuration
you need that weekend (but this may not work so well for mixed mode
contests).

So try the simple 50W calibration test on 40m to see if it makes any
improvement.

As for KPA1500 output power variation with temperature, it is annoying, and
it seems to vary from KPA1500 to KPA1500, perhaps depending on how many
other devices or heat sources are located near the ventilation holes.  The
best option when operating a contest seems to be to set the KPA1500 minimum
fan speed to 1, so that amplifier doesn't heat up too quickly, maintaining
a more stable (but not perfectly stable) power output level.

I just tested this an it works perfectly.  If DIGOUT1 is ON, and TX INHIBIT ENABLED in the amp., the amp. does not KEY even though it remains in OPER mode.  As soon as you set DIGOUT1 OFF (which will happen automatically on other a bands), the amp. is keyed normally.  Please try this.

 

3.      On ssb and had TX Test mode selected so as not to TX.  When I hit
the paddle the amp goes TX mode and actually put out a little RF on the
LP100 meter.  Should not key amp in my thinking.

 

TX TEST mode has always closed the relay and keying lines even though the rig is putting out no RF.  This is a safe way to test your keying relay connections and amp. keying light, and perhaps it also protects the receiver from getting a bunch of internal noise from inside the radio, so that is working as designed.  Any RF you see could be caused by some static when the amp relay is keyed, nothing more.  The K3 puts out no power when in TX TEST mode, even if you have CW in SSB enabled and tap the key (which you probably did at some point by going to CONFIG: CW WGHT and tapping [1] to enabled it, which is useful in VHF bands it seems.  You can disable the feature if you don't want RF to come out or don't want the relay to close while you're in SSB mode and accidentally tap the paddle.

Actually, it does.? I reported on this in a message to the reflector titled "TX 
Test Mode Garbage"? dated 7-25-2017

As a follow up Wayne wrote:

Hi Wes,

TX TEST mode activates the entire TX strip because it turns on PTT to test the keying of downstream devices. This was requested by our original field testers. The only thing that isn?t turned on is the carrier. It could be that in SSB modes there?s noise in the voice passband, producing the result you observed.

I can clarify this in an errata item for the owner?s manual.

It may also be possible for me to disable the TX AF path via a DSP command, and I?ve added that to the firmware task list.

Thanks for the input--

Wayne"


Unfortunately, as I responded, I first observed it in CW mode, and I had at the 
time, confirmation from three other guys who observed a similar situation.

I think users of the AX1 would be better off thinking of IT as the 
counterpoise, and making the most out of what they normally consider to 
be the counterpoise wire.

Look at it this way.? Unless you have a lot of current on the shield of 
the coax (in which case IT is doing a lot of radiating), roughly equal 
currents are going to try to go both ways from the feedpoint ... into 
the AX1 and into the "counterpoise" wire.? The AX1 is typically 
physically shorter and it certainly has more loss, and since the 
radiated field is a function of net current and length, in most cases 
the counterpoise wire is at least trying to do the most radiating.? I 
say "in most cases" because the typical position of the counterpoise 
wire puts it along the ground or near some other RF-sucking structure.

In my opinion, probably the best way to use the AX1 is to put the 
counterpoise wire as straight, high, and in the clear as possible and 
let the AX1 act like the shortened other half of the circuit (i.e., the 
counterpoise).? If that isn't possible, make the counterpoise wire as 
straight and vertical as possible ... climb a tree and let the wire hang 
down.? ;)

If I had a good EZNEC model of the AX1 I'm pretty sure I could prove 
that assertion, but for those who have an AX1 I'd bet some field 
strength experiments would bear me out.

I'm not saying that the AX1 isn't a worthwhile investment, and I'm not 
saying it doesn't radiate.? I just think there are some misconceptions 
on what it's actually doing and how to best make use of it.

It?s designed for /PM and stealth ops. In many other situations, of course, a longer/higher antenna will be more efficient.

I need some help on this. I am using the KX3/PX3 as a 10meter IF for my 10.368MHz EME rig. I am also using it with the? QRA64 EME communications program. I'd like to have an audio output I can use from one unit or the other that is not AGC controlled to use for monitoring the sun or moon noise as I operate. Any suggestions?

Certainly true, and it's great for that, but a lot of the posts here 
have been about people using it for more than that ... like camping and 
restrictive locations.? I'm just saying those folks could get more out 
of it by treating it differently, and it would serve a very useful 
purpose in that function if they did.

Dear Charlie,

be noted that even if the radio shows K3S on the front panel it does not
have to be the K3S inside.

There is possible to buy K3S "facelift" kit on eBay which allows to your K3
looks like K3S...:)
(...they say "K3S esthetic upgrade kit")
https://www.ebay.com/itm/Elecraft-K3S-Esthetic-Upgrade-Kit/273980434356?hash=item3fca81a7b4:g:mKkAAOSwnh5cVLdO

I am staying glued to my old K3 (fully upgraded to almost K3S level but with
genuine old look, hi) in shack. No K4HD planned as I do not see any benefit
in term of RF parameters...

I wish Elecraft the best of luck with the K4, and I am sure they will 
sell a lot of them. I am keeping my loaded and upgraded K3, serial 
number 0007. I am sure the K4HD would provide slightly better 
performance and probably an improvement in usability, but my K3 is 
already more than good enough for an old guy who is not "performing" so 
well himself anymore.

N.S.

I typically run my KPA500 fan on #1 when operating FT-8.? It will ramp 
up to #3 when the temp reaches 60?C? and during extended exchanges, but 
quickly ramps back down to #2.?? I don't find this at all 
objectionable.? ? I've never seen the TEMP above 60?C or so. ? ?? And at 
#1 the fan is hardly noticed. For SSB and CW I run the fan on NORMAL.??? 
My station is on one level, side by side in a bookshelf arrangement.?? 
Thus it is close by my listening position.????? The computer and desk is 
to the right, only 2 ft from the radio.?? Just my findings and observation.

I'd say from your QRZ picture, the amp being in the corner of the room 
allow the corner to act like a large horn.? That does one no favors for 
the sonics.

Don't sell the K3 short.  The basic K3 is still one of the finest radios 
ever made and the difference between it and newer radios is hardly 
noticeable to the human ear.

I suspect in a strong signal Field-Day or contest environment,  the K3S will
still outperform all versions of the K4 except the high-end K4HD.

I try to be objective about my Amateur Radio purchases, but don't always
succeed.  

When I was thinking about upgrading from my K3 to a K3S, I got a quote from
Elecraft for the upgrade, then I made a list of the K3S improvements and
calculated my incremental cost for the upgrade, assuming a sale of my used
K3.

For me, the cost/benefit ratio was just too high, so I stayed with the K3,
which is the best performing transceiver I've ever owned.  It's still a joy
to operate every day.

When the K4 is in full production and shipping, I'll make these same
calculations again.   With used K3 prices lower now, the cost/benefit ratio
will likely be even higher - but the K4 feature set may tip the scale in its
favor.

OK, back to working what DX there is with my trusty K3 ...

- 73 and good DX de Mike, K6MKF, NCDXC Secretary

Subject: [Elecraft] AX1 Loaded Whip Antenna
Message-ID: <32c7a23a-5b2a-9f07-e0e1-35a52aec64d3@verizon.net>

I ran some comparison tests on 20M with the AX1 against my Buddi Stick 
vertical when I first got it. I found the best performance was with the 
AX1 on a table top tripod on a picnic table with 2 resonant radials. The 
AX1 was about 1 S-unit down compared to the bigger antenna over a 22 
mile ocean path. During these times of low critical frequency short 
paths are dead and the lower radiation angle of the vertical is often 
better than a low dipole/Inv-V.

I find the AX1 most convenient for quick deployments.

The high-value, low-temperature-coefficient trimmer capacitors leveraged in the design are no longer available. Unfortunately we don't have staff available to redesign the board to do it in another way, and demand is low.

The transverter interface by itself could live on a smaller board. Schematics are available if someone would like to home-roll a replacement. We could supply small quantities of the programmed PIC16C621 that runs the module (cost TBD).

Concerning the output variation, I?ve noticed that when I change bands while the amplifier is hot, the output on the new band starts out high, then gradually drops. This would seem to indicate that the LPF is heating, and that the loss in the filter is several hundred Watts. That?s no big deal if the filters are properly cooled, as they apparently are, but still requires manually riding the power control.

I think you'll find that for a short vertical radiator and a single counterpoise wire the maximum radiation is in the direction of the wire. EZNEC confirms this and I've tested it with a friend the length of California on 40 m where with the counterpoise pointed away from him I could barely copy him, flipping the wire 180? brought his signal up significantly. He saw the same thing on his end.

Not trying to start a disagreement here, but I don?t see the point.

If you want to run a wire antenna, then, good gracious, run a wire antenna.  They work pretty well portable.  I carry two in my bag.  But I fail to see the rationale of using the AX1 as a ?counterpoise?.

It seems like the K3S has been grouped together with the K3. The K4  
will be a different animal. Like K3ICH, I have three K3S's and with  
any software I have to select K3 as the rig. The K3 has been out of  
production for years. I have seen a number of K3 ads listing the radio  
as K3S, here is one current eBay example of this false advertising  
(watch for word wrap):

Bear in mind, if your radio does not show K3S on the front panel, it  
is a K3, albeit upgraded, but  NOT a K3S.

The new synthesizer boards will improve performance, but there are  
some subtle differences between a K3 and a K3S that no amount of  
updating with new boards or mods can change.

While the K3 concept of buying a newer "upgraded" synthesizer board  
for example,  rather than a new radio sounds like a great idea which  
will surely change the performance, I feel it is NOT a feasible

My particular course of action was to sell my K3 after I had taken out  
what ever options I could add to a new K3S.
That way, I get the latest production changes (note, there ARE a  
number of them pertinent ONLY to the K3S) and,  no junk boards are  
generated.

Too bad I can't do the same thing with the K4.

Dave's observation is about how the antenna actually works, as 
determined by Mother Nature, and, depending how the antenna is rigged, 
he's probably right. Antennas work by carrying RF current, any end fed 
radiator needs a counterpoise, which, because it's carrying the same RF 
current as the end fed radiator, CAN ALSO RADIATE. Indeed, this antenna, 
depending on how it's deployed, can be thought of as an off-center fed 
dipole.

Back when I lived in Chicago, I had another "ad hoc" antenna that was 
effective on 80 and 160M. My shack was on the second floor, the antenna 
was a loaded resonant dipole tuned to 80 and 40 that sort of worked on 
30 and 15, and was fed by vintage 75 ohm Belden "kilowatt twin lead." To 
use it on 160M, I ran two wires down to both sides of a wrought iron 
fence that ran around my front yard (both sides because it was broken by 
a gate). The wire and the fence functioned as a counterpoise, and the 
vertical wires radiated (and modified the resonance). As it turned out, 
that antenna loaded that way worked better on 80 than it did loaded as 
dipole, simply because the dipole wasn't very high (35-40 ft). I'm 
reminded that my buddy KK9H used the air conditioning ducts in his home 
as a counterpoise on 160M. We've worked several times since I moved to W6.

There are photos and a description of my Chicago antenna weedpatch 
(won't dignify it by calling it an antenna farm) in

The point you're missing is that the AX1 wants (needs) a wire 
counterpoise to work very well at all, and since it's that counterpoise 
wire that is doing most of the actual radiating you're better off trying 
to optimize what you do with it.? I don't see how that is so difficult 
to understand, especially since there have been several testimonials 
here that say the same thing ... the AX1 works much better when you keep 
the wire "counterpoise" (actually the primary radiator) as straight and 
in the clear as possible.

To each his own. I own two 2008-vintage K3s, each with second RX, 
several roofing filters, 100W amp and tuner. I also own a single-RX K3, 
bought used from a list member, with no tuner, and the same selection of 
roofers. All three have the new synth board, and the first two have the 
new transverter interface (to get the improved preamp), the spare has 
the old one. I view the new I/O board more of a convenience by the 
integration of the USB interface, and I didn't go for it.

I consider these radios 90% of a K3S from a performance point of view. 
Indeed, when the K3S was introduced, I was able upgrade simply by buying 
those boards, without having to buy a new radio (as you would with any 
other manufacturer. That's one of the great things about Elecraft's way 
of doing things! And if I decided to sell them (not likely), I would 
describe them just as I have here -- 2008 vintage K3s with selected 
upgrades.

John -

It is interesting that the seller of the K3 from that estate does
acknowledge that it is not 'really' a K3S, but justifies listing it as one
because of unspecified upgrades. It sure is important to pay attention to
details.

An upgraded K3 (synth, other)  is far better than a mere 90% of an S.  Where?s the 10% as far as actual performance (not just a dB or two here and there) is concerned?

Of course, you could (it was originally talked about but never offered as an ?official? upgrade, but you can order it as a part now) buy a K3S 4-layer RF board, re-kit your K3 and put it in.  But, honestly, the difference between the radios is in the margin.  If it had been THAT much better it would have been the K4 and the new one would have been a K5.

I have more than a little sellers's remorse over parting with my updated K3, but I?ll get over it ? maybe this Winter.  Although even that likely may not be a better radio than a K3 with the critical updates, at least until the hybrid ?H? update is released.

It is always important with an Elecraft radio to pay attention to the 
details - Serial number,options installed (including filters), and 
upgrades installed are always the minimum essentials.

I don?t think I?m missing anything.  You?re basically arguing for an elevated counterpoise.  Of course the AX1 needs a counterpoise.  And I run an elevated counterpoise on most of my portable vertical antennas. 

My 31? portable wire works better than an AX1 most of the time.  It?s not always convenient or possible to put a wire in a tree.  And a wire counterpoise for your AX1, 3-5? off the ground, straight as an arrow, won?t radiate much anyway (although it can help adjust the native imdedance of the AX1/counterpoise system).  When I walk to the dock, I take the AX1 and the recommended counterpoise.  The counterpoise goes over the end of the dock ? no trees down there :-)

I?m not saying that an elevated counterpoise won?t work with the AX1, just that I?m having trouble getting my head around considering the wire as the main radiator, and the AX1 as a counterpoise???

Of all things this weekend I picked up a late model K3/10 (7928) bare bones except it has both receivers which I thought unusual.  It has the 2.7, 500 and250 filters in the main receiver and only the 2.7 in the sub.  Both Synthesizers are of the older version.

It is easy to cancel the radiation from the 'counterpoise' - use 2 equal 
length wires running in opposite directions from the base.  The 
horizontal radiation from each will cancel, and all you have left is the 
loaded vertical radiator to radiate with vertical polarization.

If they are on the ground, the cancellation may not be as uniform.
For further information read the section on verticals in any Antenna 
Handbook - even my Antenna Handbook from the late 1950s cover it.

When I walk to the dock, I take the AX1 and the recommended counterpoise.  The counterpoise goes over the end of the dock ? no trees down there :-)

Yes, of course.  I know how things work. And I agree with Don?s comment that came in in another email while I was typing. That does NOT mean the vertical element is the ?counterpoise" to a long elevated wire (or more than one) a few feet off the ground.  Yes those wires may radiate, but probably not where you want them to, unless you want to talk straight up.

Like I?ve argued, if you want a wire to radiate, put in in the air.  And if you do that, there?s no point in having the AX1 in the system.  That?s all.

Over and out, SK :-)

I'll try not to beat this into the ground here, but I think the physics 
here is important.

As K9YC said in his reply to you, equal currents go in both directions 
from the feedpoint ... to the AX1 and to the counterpoise wire.? That's 
simply physics, and it's true unless currents on the shield of the coax 
cause imbalance ... in which case the coax is doing a bunch of radiating.

Now then, what is important is what happens to those equal currents.? It 
doesn't matter if one side of the feedpoint is the AX1 or if it is the 
"counterpoise" wire ... they are both simply loads as far as the 
feedpoint is concerned.? Read that again ... it is THE critical concept.

Current generates a radiated field.? That is simple physics. Resistive 
loss dissipates energy instead of radiating it.? That is also basic 
physics.? To a lesser extent, current distributed over a longer length 
is a more effective radiator than a shorter length even disregarding 
impedance concerns.? Consequently, a short, lossy "load" is going to 
radiate less RF than a longer, less lossy "load".? Straighter is better 
than snaky.? All of that is fact.

Unless you have a very short counterpoise wire it is going to try to do 
a better job of radiating RF than the AX1 if you give it a chance.? Keep 
it as straight as possible and keep it clear of ground and other RF 
dissipating structures.

That doesn't mean that the AX1 isn't serving a very useful purpose. It 
is.? It is allowing you to feed current into the "counterpoise" wire 
with a reasonable feedpoint impedance.? That's critical.? But it doesn't 
mean that the AX1 is doing the bulk of the radiating unless you aren't 
using a counterpoise at all.

Hope this helps.? 73,
Dave?? AB7E

I just redid my Transmitter Alignment on my K1, using a wattmeter, which I
didn't have when I originally built it.  I have removed the Antenna Tuner -
now on to redoing my TX Offset - to do that do I leave the Antenna Tuner off
and proceed, or do I reinstall the Antenna Tuner and then proceed with the
TX Offset Alignment?  (As described on page 47 of the manual - the part
where you install a jumper between the OFS pads, turn the AGC OFF, set power
to 1.o watts and Adjust C13.)

 

Any help is much appreciated - I've determined I'm not transmitting on the
same frequency on which I'm receiving and am thus attempting to get the TX
Offset properly set.

I'm generally walking when I use the AX1 (pedestrian mobile, or /PM). It isn't possible to elevate the radial under these circumstances; it drags on the ground. The whip is the radiator.

What makes you think the wire isn't doing the bulk of the radiating just 
because it drags across the ground?? Actual RF ground is usually some 
distance below the surface, sometimes several feet.

There is a way to prove me wrong on all of this.? Connect two AX1's to a 
Tee connector coming directly out of the rig.? Position them vertically 
so that they act like a vertical dipole.?? Use the rig's antenna tuner 
to make sure full power is getting to the combination.? Have somebody 
measure the signal strength at different positions around a circle some 
distance from the rig/antenna.

Now replace the lower AX1 with the recommended 13' piece of wire, again 
using the antenna tuner to hopefully feed the same amount of power to 
the AX1. ? Take the same signal strength measurements ... again around 
the circle in order to try to take into account any directionality of 
the wire if it isn't mostly vertical.

If the AX1 by itself was doing most of the radiating the 2nd AX1 would 
be a better counterpoise than the wire.? That's not debatable.

73,
Dave?? AB7E

Tom,

You can reach the trimmer with the band board and tuner in place.  Just 
put the OFS jumper in place and follow the instructions in your original 
manual.  The newer K1s have a switch on the bottom instead of the OFS pads.

Guys - lots of very good info here, but we are beating this into the ground. 

Lets end thread thread for now in the interest of maintaining a reasonable list SNR. ;-)

Go out and operate, experiment with antennas, including the AX1, and see what has been discussed in this thread is best for you in your operating situations.  And of course, have fun!

Message-ID: <53fd78a0-1069-3fc1-27f5-bc5bbafa64a5@verizon.net>

I have K3S #11832 factory assembled/tested.
Came home, worked well for several month plus and now this...
On start, I get error message PA1. When checking the <CONFIG: PA TEMP> 
it indicates 57C upon a cold start. When trying to calibrate the PA 
temp, the available adjustment range varies between 57C to 97C which 
doesn't seem right by any understanding. The front panel temp is around 
25C which I take to be correct. Also, I cannot get the cooling fans to 
run with any setting of CONFIG switches or radio conditions. I've read 
every manual that I have but cannot find anything that points me in the 
right direction. Any and all suggestions much appreciated. Thanks.

Message-ID: <20190828164038.iuql2bsxtf4g4khm@n0nb.us>

I received a note this morning advising that I should check my ALC as he
is seeing some energy on USB when I check into a 75m voice net on LSB.
I am using an MC-50 microphone and am running the mic gain at 35 and the
compression at 11.  My thinking was that generating opposite sideband
energy would be quite difficult with the K3's DSP.  Am I wrong?

I'll try working with him some morning and back down the mic gain a bit
and see what that does for him.

Nate,

One thing is that you have a LOT of compression. That may be causing his 
receiving to show excess energy, maybe even lapping over into the 
opposite sideband.

First set the compression to zero, then either connect a dummy load or 
use TX TEST and adjust the mic gain for 5 to 7 bars on the ALC meter - 
the 7 bars should be seen only on peaks.

After that, you can increase the compression, but I would limit it to 6 
dB for normal operation.

Don W3FPR

Although the manual doesn't say so, according to an ARRL review, the K3S is 
specified to have undesired sideband suppression of >50 dB.? ARRL claims an 
optimistic >70 dB.

So if you are extremely strong at the other guy's place, he might easily hear an 
opposite sideband, even though your radio is operating correctly.? Ask him what 
the ratio is.

I don't know about others, but when I got my K3 I did a lot of testing 
into a dummy load using my previous rig with a short piece of wire for 
an antenna to monitor my K3 audio.? I found anything above about 25 for 
mic gain was objectionable, at least to me.

I find the AX1 most convenient for quick deployments.

Hi Fred, 


The ALC level you recommended is the recommended level for digital modes such as FT8 where no ALC is the standard practice. 
Elecraft's recommended for the K3 or K3S ALC level when operating in voice modes is 5-7 bars. 


The exact quote from page 30 of the latest K3S manual 
https://ftp.elecraft.com/K3S/Manuals%20Downloads/K3S%20Owner's%20man%20A1.pdf 


Optionally select TX TEST mode (pg. 13) or set power to zero. This will not affect your CMP/ALC bar graph readings. 


Set CMP to 0 


Hold METER to select CMP/ALC metering 


While speaking into the microphone in a normal voice, adjust MIC for a peak ALC meter indication of about 5-7 bars (see below). 


Adjust CMP for the desired speech compression level while speaking.The CMP scale shows approximate compression level.

Numerical readouts for Mic Gain and Comp are pretty meaningless, because 
the output of good mics varies widely from one model to another, how 
close the mic is to the mouth, how loud we talk. The right way to set 
(and understand) these controls is to look at indicated ALC and CMP on 
the bar graph display while transmitting. Both adjustments should be 
made AFTER setting TXEQ. I have long advocated 10 dB of indicated CMP on 
voice peaks.

It is well known that IMD in the K3 and K3S increases when operating 
from low DC supply voltage. It also increases when the output stage is 
operating near its limit, and when the antenna is not well matched to 
the output stage. If the 100W amp is present, it does not engage until 
output power is set above about 15W, so IMD is also higher when running 
12-15W. The increased IMD of the 100W state can be clearly seen in this 
set of data.  DC voltage was in the range of 12.5V for these 
measurements. http://k9yc.com/P3_Spectrum_Measurements.pdf

Pink noise is widely used by audio professionals because its spectral 
distribution more closely corresponds to music and speech than does 
white noise. For that reason, pink noise is the best test signal for the 
evaluation of speech processing systems (like CMP and peak limiting).

Wes,
     You make a very good point. The unwanted sideband will not be 0; 
there will be some "residue" that can be heard if the signal is strong 
enough. And, a lot has to do with the measurement method at the 
receiver.

     Years ago, I was running DSBSC using a Globe DSB-100. I was told 
that my carrier was way down but my unwanted sideband was only 20 db 
down. That was interesting as I made no effort to suppress my unwanted 
sideband. The problem was the method that was used to make the 
measurements and the strength of my signal. So, determining the ratio of 
the two sidebands might be difficult, but it may be the correct 
approach, However, it will require being able to "see" both sidebands on 
an equal basis.

73,
Barry

What has any of that to do with opposite sideband rejection?

Wes? N7WS

BTW, The HPA kicks in at 12 W.

I agree with  Jim and what I tell hams every day since I seem to talk to a
bunch of them on the phone.

Do NOT use the settings other tell you, set up the radio by using the
Meters in the radio, in this case the ALC. That is the reason it is on the
radio.

The more ALC you have, the  more the radio is already shutting down down
your audio gain and hence the reason it is called Automatic Limiting
Control.

I am not a big fan of compression and in today's world there really is no
requirement to have it on.  Ask anyone who has been DXPedition end of a
DXPedition and they will tell you to turn it off as it is actually harder
to understand you.

It 'might' look like you have more power out, but it is not really in a
good way.

This is also a good time to review page 28 on "Voice Modes" and follow the
steps the way the Engineers who designed this want you to set up your
radio.  They are pretty smart people.  :)

I hope that helps, Mike va3mw

Barry,

With my SDR-IQ looking at the K3S i-f output I can see the other guy's 
signature.? I suppose a P3 does the same.? It's pretty amazing to see some of 
the lousy signals when we have such improved technology.

This is NOT true if compression is well adjusted -- 10 dB of well 
adjusted compression increases talk power by 10 dB, and setting TXEQ to 
remove speech content below 400 Hz helps by another 3 dB. It is the 
abuse of compression that reduces intelligibility. Compression has been 
universally used in all broadcasting modes for at least 60 years, and 
for at least 40 years, for gain reductions of 30 dB or more! The joke 
among FM broadcast engineers in the '70s was "If the meter in the 
modulation monitor moves, the program director will say we're not loud 
enough!"

Yes, I know what the manual says.? However the IMD on my K3 goes up when 
I set the mic gain to flicker bar 7 on voice peaks so I run it with 
almost no ALC.? I also set the TX EQ using the "K9YC Method," and 
regularly get unsolicited "great audio" comments so I'm a fairly happy ham.

I'm not on SSB often, but when I do get on such as NAQP SSB, I'm always 
a bit surprised at how many signals have all the sideband energy crammed 
right up against the suppressed carrier.? Not too many fill up their 
BW.? For those of us with compromised hearing, it makes copy difficult 
... one of the several reasons I don't get on phone very often.? All 
that low frequency energy contributes almost nothing to intelligibility.

Yes. I regularly see signals from SSB ragchewers with splatter in the 
suppressed sideband only 10-15 dB below signal in the intentional 
sideband. The data in the link I posted was with a P3 on my second K3, 
with the K3 being measured into a dummy load.

I've alerted guys on 6M about this, suggesting they turn down drive to 
their amplifier, and they said they didn't have an amplifier. When I 
asked what rig, it was one of the low-cost do-everything rigs from one 
of the big JA mfrs. When I posted this at the time, W4TV described the 
mechanism (I think I remember that it was a shortcominBefore Elecraft 
rigs took over Field Day, These cheap rigs (and even some much more 
expensive ones) have long been considered the scourge of Field Day.

It seems like often Jim and I disagree on things, but this time I'm in total 
agreement with him.

About a year after my speech processor paper was published in Ham Radio Magazine 
(http://k6mhe.com/n7ws/S_PROC.pdf) I worked a guy in the PNW, on ten meters. He 
was running a homebrew 2 watt radio and using a copy of my processor.? He was 
delighted with it and the fact that we were talking.? Frankly, it was the first 
time I'd heard one from the other end.? So he wanted to experiment.? He was 
about S2 but perfectly Q5.? When he turned the processor off he was gone. Not a 
peep.? It was amazing. Frankly, I was impressed.? I knew the theory but to see 
it in action was eyeopening.

I ordered mine.

Looking at the instructions,  "If you?re using the ATU in a KX2 or KX3,
note that tapping ATU TUNE a
second time within 5 seconds may find a better match."

I never knew this.

I see note to attach the radials to the transceiver near the antenna jack. If
using a short coax to mount the antenna on THE Elecraft tripod base, is
connecting radials to that base preferred or is connecting them to the
transceiver still advised? I use the Elecraft AX1 radial and a separate
radial cut for 20m now, connected to the antenna base rather than KX2
chassis. I'll probably make another 40m radial and mark it to roll for 20m.

Message-ID: <BYAPR16MB29683EBADC3CCE9BE2E1092C8CA30@BYAPR16MB2968.namprd16.prod.outlook.com>

"The more ALC you have, the more the radio is already shutting down down your audio gain and hence the reason it is called Automatic Limiting Control."

Can you please cite any modern rig, preferably with reference to the schematics, for which ALC is applied to the audio signal?    For the rigs I have studied ALC gain is applied somewhere in the Transmit IF, long after the modulation is applied.

Can you please provide any reference that defines ALC as Automatic Limiting Control?

Either would work, especially since you need an ATU to match on 40 and 30 meters anyway.

The ATU requirement is clearly spelled out in the product info -- hope no one missed this :)  Short whips can be very narrow banded.

When I installed the upgrades in my K3, I kept the old boards. I've come up with two uses for them.

  * Give them to people who post that they want them. (One Synth board give away).
  * Use them to practice surface mount rework. You can even test the reworked board.

I think I better take a mea culpa on this one.  One reply in a private
email asked if I was using and amp and whether I was driving it too
hard.  Well, some mornings this week I have depending on static levels
and I operated the KS QSO Party this past weekend and ran 100W.  I
normally run the amp (ALS-600) with the power setting at 70W.

This is probably just a, "D'oh!" moment.  Yes, the K3 was still set for
100W.

Incidentally,  My COMP runs about 2-3 bars on voice peaks and the ALC
meter is in the 5-7 bars range on peaks as well.

It's a PEBCAK3 issue.  ;-)

Hi Fred  (Skip)

Sadly, many of those are splattering so wide that you can hear them on the
opposite sideband.  Unfortunately, a report of great audio does not mean
great IMD performance.

Don't take this the wrong way, I am not saying you have bad IMD it just
that you can't relate the 2 has being an indicator.

With a good radio and a good waterfall you can see it plain as day.  There
are a few locals (aka here in ve3 land) that I 'watch' routinely with their
top end Yaesu's (5000's) and they sound awesome, but they have the absolute
worst splatter you have ever seen.    One guy on 80M was absolutely
understandable when I listened to him on USB.

Nate, glad you got it figured out.   I'm sure we have all been there (me
included).

73 all, Mike va3mw

We've made great technical strides in receivers.??? Transmitters, well 
they are best described still as "out house" technology. Nothing has 
changed of significance in 25+ years.? In looking at my P3 and SSB 
signals on the bands, there are lots and lots of really bad signals.?? 
Yet I? most often hear "great signal" given as a report.

I find a lot of the opposite sideband splatter is originated from 
mis-tuned amplifiers or amplifiers which are driven too hard.?? If it 
isn't "linear" it is a splatter generator.??? And linear means just 
that, linear.? For an amp to be linear, it must amplify all signal 
levels the same amount.? Most amplifiers begin to show some degree of 
signal compression at the upper power rating limits. Pushing one past 
these limits even the slightest amount, generate significant amounts of 
opposite sideband splatter.

So very true.? I'm about as far removed from being an AM/audiophile type 
of ham as you could imagine, but I've heard guys getting "great audio" 
reports when they sounded like trash with lots of clipping. It's really 
sad, and I tend to err on the conservative side because I'd rather give 
up a bit of "punch" than be one of them.

Hi,

I am coming back after some time to ask if you already found the time to
make pics of your collection.

Specially I am looking for Safari-4 and Koala pics as I am compiling the all
Elecraft line-up from the first product until the K4HD...hi.

Subject: [Elecraft] KPA-1500 on digital modes
Message-ID: <dc344b06-b6de-ce06-615e-0b4b9f9c6776@comcast.net>

Elecraft's published specs rate the KPA-1500 for 1500 watts output on 
all modes.? In prepping for this weekend's contest, I've been running it 
at closer to 700 watts, because I've found that even just running on CW, 
with its much lower duty cycle, my amp reaches 70C quickly.? I don't do 
that much digital contesting, though, so I'm wondering whether 1500 
watts output is on digital modes is realistic or a recipe for trouble.

I have measured the TX IMD performance of my and 2 other K3S transceivers. In my opinion it is not possible to have anything other than mediocre TX IMD performance from a K3S or a K3 at ANY power level. I am so disappointed with this aspect of the K3S. The  mass market and cheap IC-7300 is better, especially on 6m. In all other respects I am very impressed with the K3S.


The transverter output on 10m when set to 0.5mW has incredibly good IMD performance so the problem is with the 2 PA modules. I have contacted Elecraft and so far they have not offered me a satisfactory solution. I think that I am going to go to the inconvenience of using an external PA on 6m.


The K3S has excellent TX composite noise all ruined by poor TX IMD. I can easily see 19th and 21st order IMD components on 6m in the 90dB dynamic range of my E4406A spectrum analyser - this rather negates the advantage to my neighbours when I'm on SSB. For CW and Digimodes then the K3S is superb. If I was contemplating the purchase of a K4 I would be asking Elecraft about TX IMD from the hopefully new and improved TX amplifier chain.


Not a happy message but it's the truth. Yes I have the latest FW, yes I have tried to reduce the gain from the driver using the settings in the FW yes I maintain the correct voltage on the PA, yes I have late (not the latest) revisions of the driver and final PA. I am using the 2 tone facility so there is no question of external or maladjusted audio non linearity. The fact is that it is poor. I also know what I'm doing.


Poor show Elecraft!

Hi Fred  (Skip)

Sadly, many of those are splattering so wide that you can hear them on the
opposite sideband.  Unfortunately, a report of great audio does not mean
great IMD performance.

Don't take this the wrong way, I am not saying you have bad IMD it just
that you can't relate the 2 has being an indicator.

With a good radio and a good waterfall you can see it plain as day.  There
are a few locals (aka here in ve3 land) that I 'watch' routinely with their
top end Yaesu's (5000's) and they sound awesome, but they have the absolute
worst splatter you have ever seen.    One guy on 80M was absolutely
understandable when I listened to him on USB.

Nate, glad you got it figured out.   I'm sure we have all been there (me
included).

73 all, Mike va3mw

This thread instigated some experiments here.? In analyzing TX IMD in both my K3 
and K3S, I've made probably hundreds of two-tone measurements using the built-in 
two-tone generator.? But in all of these measurements I never questioned what 
the audio level was, since it's not adjustable, except for balancing the levels 
of the tones. So I set up a measurement and went to transmit and then using the 
K3 utility used the get "BG" command to read the ALC bar graph.? The answer was 
zero bars.? I found this interesting.

To explore further, as a proxy audio signal generator, I opened WSJT-X, FT-8 
mode and used the "Test" button to generate an audio tone.? I used both the K3S 
internal sound card and the built-in card in a Lenovo Think Pad as a double 
check against generator distortion.? I saw similar results with both.

And what are those results you ask.

Using a spectrum analyzer and looking at the K3S output on 14 MHz in this case, 
using a low tone (500+ Hz) I noted that at any audio level that drove the ALC 
indicator to four bars (even flickering), there was low level garbage that 
appeared in the TX passband.? It took reducing the level to three bars to clean 
it up and in my radio there are either three bars or none, no one or two, when 
reducing the gain.? The "BG" command confirmed this.? Above four bars, things 
only got worse. Understand this was low-level stuff down in the weeds and not 
the dreaded audio harmonics that WSJT-X "split" is supposed to prevent.

I've never been one of those handwringers worrying about using ALC, as I believe 
just like AGC in receivers that we all use, properly designed it should work 
well for its intended purpose. Now, I'm not so sure, perhaps I've been wrong or 
I'm saved by the "properly designed" clause.

Pete,

I don't run my amp at full legal limit on digital modes, but typically set the input power for about 1000 watts output. One of the interesting characteristics of the amp is increased efficiency as power increases. At 600 watts efficiency is only 38%, whereas at 1000 efficiency increases to 50% and at 1500 watts to 60%.

You seem to be assuming that the KPA1500 will run hotter at 1,500 W output than it does at 700 W output.   I have no data for the KPA1500 but my data for the KPA500 show peak heating is at about 250 W RF output.   If the KPA1500 is similar then 700 W RF output will be close to worst case heating.

If you want to reduce heating then ensuring the load is as well matched as possible may be more productive than running at reduced power output.

It's interesting that the heat that has to be dissipated is pretty close
to 1000 watts in all these scenarios! Running the amp at less than full
power buys you nothing.

Pete,
For FT4/FT8 or any other digital mode TX Equalization is set flat automatically when you select DATA mode.

If you run in data mode, the TX and RX equalizers are taken out of the loop.  No need to reset them.

Pete,

If you are using DATA A mode, that is done for you automatically.
OTOH, if you are "doing it the hard way" and using USB, then the answer 
is yes, and also set compression to zero.

Hi Pete, 


Are you sure that your minimizing SSB voice frequencies above 2000 Hz? 
I hope that's a typo, because its fundamentally incorrect. 


Its perfectly okay to use SSB mode with FT8 and other digital modes, 
but you MUST set TX equalization to flat and CMP to fully 
counterclockwise. The MIC level must be set so with the fifth ALC 
bar just flickering, this assures that ALC is off.

No, that was indeed a typo.? The way it is normally set for SSB 
emphasizes the highs. Trouble is, I don't operate phone enough to catch 
things like that hi.

"Am I right to assume that I should set it back to flat when doing FT4/8?"

If you do FT4 and FT8 right, as in using WSJT-X "split mode", the signal modulation frequency cannot be outside the range 1,500 to 2,000 Hz.  Why would it be desirable to have a flat TX equalizer response?

Flat is certainly desirable for RX and for some rigs Flat is not the same a None.

Andy,
     First, I suggest that you use data A mode. This will automatically 
set the equalizer and audio compressor correctly making it so that you 
don't need to play with adjustments, except level.

     Second, the tones used CAN be much lower than 1500 Hz. I have worked 
station that were down to 200 Hz. And the the tones can go as high as 
the sending stations transmitter will allow, typically less than 2.7-2.8 
KHz. This assume that that you have tuned your radio the the FT8/FT4 
frequencies correctly.

Equalizers introduce phase shift.? Even the very best ones do that.?? 
Thus for a phase shift audio signal, either transmitted or received, use 
of any EQ can and will introduce phase shift in the audio path.?? It is 
not at all advisable to have this occur with digital signals.

It is highly advise about to use SPLIT function with WSJT-X, FT-4 and 
FT-8 modes.? If your radio is old and slow and does not quickly switch 
between VFO A and VFO B, the Fake It is suggested.

The transmitted signal frequency is the suppressed carrier frequency plus the modulation frequency.  The presence of a signal at 200 Hz, or 4,000 Hz, in your receive waterfall  is not in conflict with the transmitter modulation frequency being in the range 1,500 to 2,000 Hz.

If you have an open mind you may learn something from this paper -

Conrad and I have corresponded about this in the past.

He is absolutely correct in worrying about the IMD performance of the K4.? I 
bought my K3S after being disappointed with the K3 TX IMD and thinking that the 
FETs would be better.? How wrong I was.? IMD was no improvement and reliability 
was awful.? At 50 VDC, they no doubt would be better but as long as Elecraft 
clings to "12-volt" radios, I'm afraid this will persist.

I can easily see 19th and 21st order IMD components on 6m in the 90dB dynamic range of my E4406A spectrum analyser - this rather negates the advantage to my neighbours when I'm on SSB. For CW and Digimodes then the K3S is superb. If I was contemplating the purchase of a K4 I would be asking Elecraft about TX IMD from the hopefully new and improved TX amplifier chain.

Yes I have the latest FW, yes I have tried to reduce the gain from the driver using the settings in the FW yes I maintain the correct voltage on the PA, yes I have late (not the latest) revisions of the driver and final PA. I am using the 2 tone facility so there is no question of external or maladjusted audio non linearity. The fact is that it is poor. I also know what I'm doing.

This was discussed here not long ago, and it is normal for any linear 
amplifier.? It needs to be biased up to be linear, and that bias energy 
ends up as heat even if you don't use it.

I worked as a component engineer at Collins Radio in Cedar Rapids when I 
first got out of college.? One of the low level RF stages (or IF stage, 
I don't remember for sure) in several of their receivers used a 
stud-mounted RF power transistor biased up hard enough to discolor them.

There is a big difference between "energy on opposite sideband" and hearing
the opposite sideband.  If you switch to the opposite sideband and can
clearly copy the intelligence, then the issue is sideband suppression.  If
you hear unintelligible audio from the offending signal, that is splatter
with many possible causes, one of which is IMD in the exciter, amplifier, or
both.

ALC is frequently abused with the offending op receiving great audio
reports.  I find many who never monitor ALC while operating SSB. Few ops
give accurate audio quality reports today, much less pay attention to TX
bandwidth when providing reports in spite of the proliferation of SDR's and
panadapters.  Most don't know the difference between RFI in the TX audio
chain and an over-driven signal.  We need to mentor our brethren to help
guide them in the right direction. 

While some might consider this nitpicking, ours is a service based on
science and facts.  However, science and facts are too often ignored.  I use
screen captures from my P3 when pointing out broad signals.  Half of the
offending ops don't have an e-mail on QRZ.com.  Half of those who do are
surprised to learn of their transmitter bandwidth "abuse."  A significant
portion of those don't care and are offended.  Fortunately, that is rarely
the case here.

73, Bill, K8TE

"Sadly, many of those are splattering so wide that you can hear them on the 
opposite sideband.  Unfortunately, a report of great audio does not mean 
great IMD performance."

They bias the LDMOS devices at 1 amp each. That is minimal in overall heat when you are pulling over 40 amps at high power.

"They bias the LDMOS devices at 1 amp each. That is minimal in overall heat when you are pulling over 40 amps at high power. "

You beat me to it.  My KPA500,  keyed but with no RF input, showed 0.5 A at 76.7 V.  That's only 38 W which is a small part of the 400 W plus PA dissipation seen in some operating conditions.

All my measurements of PA dissipation take PA DC input and subtract RF output so my data include dissipation in the LPF.  It would be interesting to separate  the dissipation in the finals from the dissipation in the LPF but I don't know how to do that without modifying the amplifier.

Pete,

Digital A is the correct K3 setting for all digital modes except RTTY. 
The equalizer is disabled in Digital A. The computer should feed the 
Line Input.

Both the KPA500 and KPA1500 are least efficient on 6M, which means that 
they produce the greatest heat on that band. My KPA1500 arrived July 6, 
right in the middle of E-skip season on 6M. I ran it as close as 
possible to 1500W, always using WSTT-X for either FT8 or MSK144. It got 
hot enough for the fans to get loud after 10-15 minutes, and eventually 
they get SCREAMING LOUD. But the amp continues to be happy. When it 
isn't, it will back off power a dB or two.

I haven't used it much on HF yet, but those who have report that it's 
reasonably quiet in heavy duty CW or SSB contesting use.

Has anyone collected IMD data on the different version of KPA3A amps??? 
I seem to recall measuring IMD when I first got my K3S, s/n 10163.?? 
Since that time I' have experienced 2 failures of the KPA3A in my 
radio.?? Elecraft replaced the last one with a newer "more stable" 
version.?? I do run my radio with 14.2 volts at the radio in transmit at 
100 watts output CW key closed.?? In RX the voltage is 14.5.??? The 0.3 
volt difference is the IR drop in the DC power cable and connector.

Guess I need to measure that one.? But hey, it too pretty and very

My KPA500 runs from a low of 35% to a high of 55% depending on power.?? 
Lower power is least efficient.?? Thus I always run close or at maximum 
rated power.??? Also the load impedance will affect efficiency.

I don't believe this is a class C amp.  We should discuss the relevance of different classes of operation of amps, and let's be honest... it will be most efficient at max output regardless of class  I believe.

I just did a quick check:

At 1500 watts eff is 56% and pwr diss is 1179 watts
    1000              44                  1273
     500              30                  1120

My Expert 1.3K-FA had 3 voltage levels:

48 volts for full power (1300 watts)
38           800 watts
32           450

I no longer have the amp so I can't check the eff at those
voltages and power levels.

Dear OMs and YLs,
     Remember that a small reduction in power, current or voltage for most
electronic components gives a manifold increase in reliability.   Not only
is it better for other users but I will bet the KPA1500 is a lot happier
(more reliable) for a 20% drop in output power which is memory serves me
right is about 1 dB drop in signal strength.

They bias the LDMOS devices at 1 amp each. That is minimal in overall heat
when you are pulling over 40 amps at high power.

Message-ID: <201908292155.x7TLtTb5024195@mail46c28.carrierzone.com>

I assume the measurements with bare K3/K3S were using 100w internal 
amp.  I wonder how the 10w version of these radios Tx IMD perform?

On 6m, I run with the KXPA100 at 11w output (K3 at very low output) 
to drive a 1000w Harris surplus TV linear (which is rated to 1600w 
continuous duty).  1000w limit is due to the 50v-50A PS input 
limit.  On 2m+ I use the 1mw transverter interface output at 28-MHz 
on my K3.  My  2m 1500w and 23cm 600w LDMOS operate on 50v and I load 
to 1-dB output compression point: 2m at 1200w, 23cm at 560w.

Any IMD analysis on the KXPA100?

I have measured the TX IMD performance of my and 2 other K3S

than mediocre TX IMD performance from a K3S or a K3 at ANY power 
level. I am so disappointed with this aspect of the K3S. The  mass 
market and cheap IC-7300 is better, especially on 6m. In all other

Good Afternoon,

 ?? It got hot this week.? As the temperature rose to the mid 90s the 
humidity dropped from its summer normal of ~ 50% down to 20%. At the 
same time the wind rose from 5 mph to 25 mph.? I had never seen the fire 
danger sign increase by two steps in one day until this week.? Luckily 
the weather has turned for the Labor Day weekend.? A slow rain started 
an hour ago so the forest is a little safer.? The wind has also lessened 
in intensity, now all those folks going to the beach can have open 
fires.? But for Smokey the Bear's sake please be careful.

 ?? I got busy so this report is late.? The same rain which has lowered 
the fire danger has also forced me inside so I can write. With all the 
list discussion of antennas I will relate my tale of moving the same 
antenna from one tree to the next.? Previously the enclosed angle of the 
V was less than 150 degrees.? I was able to raise the center by a few 
feet and each end by about twenty feet. Now the interior angle is about 
165 to 170 degrees.? Since propagation has been changing very slowly 
lately I can assume with some confidence that my flatter antenna 
radiates more strongly to the NE and SW.? Before, with the lower angled 
V, I had a more circular radiation pattern.? Now it is more consistent 
with that of a dipole.? On 40 meters this difference was less 
pronounced. But, then, the antenna is not 1 wavelength above the ground 
at that frequency.? I expect the wet trees from the current rain will 
change things for this weekend's nets.

Subject: [Elecraft] A few thoughts on the AXE1 extender
Message-ID: <D2EECB55-2552-4194-8F02-FFDA92BEF7AA@elecraft.com>

It's a poorly kept secret that the AXE1 40 meter extender for the AX1 whip is now available...info at:

    https://elecraft.com/products/axe1_40-meter-antenna-extender

I've been using a prototype AXE1 all summer, so I thought I'd share my experience. 

The AX1 (with or without the extender) is intended for a few specific scenarios:

   - pedestrian mobile

   - "stealth"

   - backup for full-size antennas

   - emergency 

Thankfully, I haven't had cause to use the AX1 in an emergency. (It may be just a matter of time. My 15 year old son and I do some pretty extreme/remote hiking.) But I have used it in the other three cases. 

My favorite place to take the AX1+AXE1 is Bedwell-Bayfront Park, on the west side of San Francisco Bay. The park is surrounded on three sides by wetlands and former salt ponds. It's a great place for weekend birdwatchers. During the week, I'm often one of few visitors. 

The AXE1 comes with a 33' counterpoise wire. This is absolutely required for transmit purposes (as is an ATU, given the narrowband nature of all short whips). Despite the length, I've had no trouble using the whip while walking, i.e. pedestrian mobile. The wire glides along the dirt trail and slips through vegetation. The whip and counterpoise together only add a few ounces to the weight of the KX2, so extended hand-held operation is possible.

As for "stealth" operation, the definition is subjective. I define it as "operating a ham radio station in public without anyone having a clue." There are times when this is useful. At the beach, you can sit in a low chair, with your radial buried in the sand so no one trips over it.

Finally, the AXE1 is a great backup antenna. Since all three pieces (AX1, AXE1, and whip) are only 6" long, it can fit just about anywhere and be called into service if, for example, your primary antenna becomes enamored of its tree. This happened to me the other day right before a local 40 meter SSB net started up. I was able to check in with the AXE1, and was heard in three states, running only 5 watts. 

Yes...you'll get out farther with a longer and higher antenna, but that isn't always an option.

40 meter operation with a short antenna and QRP is definitely for the adventurous. But every QSO, even with someone across the bay, brings back memories of when I was first licensed. When QSOs were magical.

This reminds me of one of the first CQP county expeditions I was 
involved in. Out plan was to use the Icom 706MII in the car on 
SSB as the main radio with the Little Tarheel screwdriver 
antenna mounted on the liftgate. The it proved too hard to tune 
the antenna with the Icom, so I switched to the backup K3/10 
which made tuning the antenna easy.

I was running 10 watts. (Having started the contest at 100W, we 
couldn't enter as QRP.) Late in the evening, I tried to make 
contacts on 80M, where the Tarheel is more of a preselector than 
an antenna. I made a few QSOs, and every station said, "You're 
way down in the noise, but we'll try to make it work." Many 
thanks to them for trying.

My lovely wife took pity on me and a new 100W board arrived soon after.

Yes. It has been mentioned on this list that the KPA500 is designed to be most efficient at 500 Watts and running at lower power does not mean saving the amp.

I?m finding it very useful to use a miniVNA to arrange 2 counterpoise wires
for 20m for low SWR *before* engaging the ATU on my KX2. A random toss of
wires might yield SWR > 9 and better arrangement < 2 SWR. I?ll try the same
for 40m but may have trouble getting those wires to fit inside a hotel room!
When the window doesn?t open I use the AX1 inside suction-cupped to the
window. I can stick it outside if the window opens but counterpoise wires
dangling straight down seems suboptimal.

Kenwood have delivered a very credible IMD performance from the new TS-890S and, indeed, even the TS-590s (especially the SG) are considerably better than the Elecraft offerings. All are 12 V radios, of course.  I use a TS-890S with a KPA1500 and, while the combination is poorer in IMD terms than my 50-yo Collins S-line, it's a great deal better than many contemporary offerings.  I don't anticipate parting with the TS-890S any time soon but, all things being equal, regard a K4 with good pre-distortion implementation as a deal maker in the not too distant future.  Indeed, I might have waited for a K4 this time around, barring the shenanigans surrounding the K4 forum discussion and announcement.

Conrad and I have corresponded about this in the past.

He is absolutely correct in worrying about the IMD performance of the K4.? I bought my K3S after being disappointed with the K3 TX IMD and thinking that the FETs would be better.? How wrong I was.? IMD was no improvement and reliability was awful.? At 50 VDC, they no doubt would be better but as long as Elecraft clings to "12-volt" radios, I'm afraid this will persist.

In my opinion it is not possible to have anything other than mediocre TX IMD performance from a K3S or a K3 at ANY power level. I am so disappointed with this aspect of the K3S. The  mass market and cheap IC-7300 is better, especially on 6m. In all other respects I am very impressed with the K3S.

I can easily see 19th and 21st order IMD components on 6m in the 90dB dynamic range of my E4406A spectrum analyser - this rather negates the advantage to my neighbours when I'm on SSB. For CW and Digimodes then the K3S is superb. If I was contemplating the purchase of a K4 I would be asking Elecraft about TX IMD from the hopefully new and improved TX amplifier chain.

Yes I have the latest FW, yes I have tried to reduce the gain from the driver using the settings in the FW yes I maintain the correct voltage on the PA, yes I have late (not the latest) revisions of the driver and final PA. I am using the 2 tone facility so there is no question of external or maladjusted audio non linearity. The fact is that it is poor. I also know what I'm doing.

K3 ? 630M band

My first K3 a few years ago S/N number in the 1300 hundreds (Kit )has preformed

Like no other Ham xcver I had ever owned. My second K3 wasfactory built.

Both have been upgraded with mod?s to bring them up to K3sstatus.

Holding an experimental Licenses I have been operating the olderK3 on the 630M

?Band for many years, the0 dbm output is enough to drive my 630M pwr amp to 100W.

For the past two weeks I have been experimenting with a newantenna for 630 meters.

The folded unipole is a winner and with a small footprint.

There is more info on my web-site.

Subject: [Elecraft] KPA-1500 Power Output Variation
Message-ID: <6a1a2a7e-dad4-d66a-0ec3-9aa79eb457b7@cox.net>

Some asked that I post results for the variable power output problem.? I 
now have a pretty good idea why output varies from 1350w to over 1700w 
at a given temperature with a fixed drive level between 7.000 and 
7.050.? The problem occurs only on 40m.? The antenna SWR varies from 1.4 
on 7.000 to 1.3 at 7.050, and 1.1 in the middle around 7.025 or 7.030.

Eventually, using the Utility, I discovered I could get very constant 
output by eliminating all tuner memories, then picking single Xl or Xc 
values _every 10 KHz_.? Values ranged from Xl = 480 at 7.000 to Xc = 121 
at 7.050, with other values in between.? That seems to be a big 
variation.? In any case, the values produced the right results when 
changed _every 10 KHz_.

Percentage change in SWR value over this relatively narrow frequency 
range is high compared to my other antennas.? I assumed memorizing those 
reactance values would solve the problem, but the tuner will only 
remember values within 20 KHz bins.? In other words, it would memorize 
only every other value.? That doesn't help.

On 160 and 80m the bins are 10 KHz wide.? On most other bands they are 
20 KHz wide, and on 10m they are 100 KHz wide.? I think narrow 
bandwidths of 40m antennas is common, so I'm hoping to see a change in 
the tuner's 40m tuner bin width to 10 KHz.

All resistances check out fine but the Frequency Counter test reads ~450kz

Any ideas?

Order a replacement J310 FET from Elecraft and replace Q19 - that should 
provide proper operation.

There was a time when Elecraft ordered a batch of J310s that turned out 
to be marginal in the PLL Reference Oscillator.  Those have since been 
replaced with NOS stock which work well.

In other words, order from Elecraft and not other sources.  The 
thru-hole J310 has been discontinued by the manufacturer.  The part is 
being produced only in the SMD version.

Evaluate the AGC calibration (and anything else) only after replacing 
Q19.  The frequency of operation is not dependable without Q19 working 
properly.

Message-ID: <29aab861-f70f-e1b6-a3f3-a7336b32d31b@roadrunner.com>

It occurred to me that the KPA1500's built in tuner might be of
some help.

Here's my reasoning. If we decrease the drive power to lessen
the output power but keep the same voltage, the amplifier wants
to see a higher load impedance.

Here are the results of some quick tests:

Base line is the amp set for 1000 watts output and eff is 44%

I the set the tuner so the amp "sees" a load of 60 Ohms (actually)
58 Ohms with the values of L and C available. Eff went up to 53%!

I then set the tuner to present a 70 Ohm load (actually 68 Ohms).
Eff went up to 59%!

This was into a dummy load. I realize that, if you're using the tuner
to match an antenna, this could be very complicated.

If Elecraft could figure some way to give us a choice of voltages
for differing power levels, this problem would go away.

73, Roger

I think I've discovered a fly in my ointment! The efficiency
that the amp displays is based on it's determination of the
output power. If the amp is looking into a higher Z load,
the indicated power is greater than normal resulting in a
higher efficiency reading.

Oh well, back to the drawing board!

"If we decrease the drive power to lessen the output power but keep the same voltage, the amplifier wants to see a higher load impedance."

Is the PA Voltage of the KPA1500 regulated?  The KPA500 PA voltage can vary about 20 V (80 V unloaded to 60 V at max PA current).

Message-ID: <02c301d56009$3e50ea00$baf2be00$@videotron.ca>

Hello,
There is a new version of Win4K3Suite available, version 2.012. This release
includes the latest EiBi shortwave database, has improved transverter
support, and now allows use of sound card based Panadapters with the
Elecraft KX2 (requires modification of the radio).

Win4K3Suite is a full featured control program for the K3/S, KX3 and KX2.
It has a built in Panadapter that works with LPPAN and a sound card, as well
as the SDRPlay RSP's. It supports the KAT500, KPA500/1500 and the KXPA100 on
most of the above radios.  A unique feature is that is has 6 built in
Virtual Radios, each of which works just like an Elecraft radio.  This
allows sharing of a single COM port with up to 6 applications.  It also has
a built in HRDLogbook server and the EiBi Shortwave database which is now up
to date.

Subject: [Elecraft] Passing Band Data from [KX3/KXPA100] to [KAT500/KPA500]
Message-ID: <95288E6B-06AA-420A-AC3C-BE6DAF639880@sfu.ca>

Hi All:

I have the setup as described in the subject line.  My KXPA100 is interfaced to my KX3 using the short Elecraft CAT5 cable.  I have recently added a KPA500/KAT500 combo.

I noted from the manuals that the [KX3/KXPA100] must really be treated as a generic external transceiver, and the two ?blocks" [KX3/KXPA100] and [KAT500/KPA500] do not communicate digitally, but are interfaced using a simple PTT line.

This is fine, and what I expected when buying the combo.  

It would be nice, however, if it is possible, to allow the band and other data sent by the KX3 to the KXPA100 to be extended to the other block, the [KAT500/KPA500].

It is this aspect that I am currently investigating.  I have the connector pinout for both ?blocks? and note that the [KX3/KXPA100] block utilizes serial transfer of data between them, where the second block [KAT500/KPA500] utilize essentially BCD for band data and an ?AUXBUS? signal that I have not yet found out much about.

As an experienced hardware/firmware/software person I am thinking that it might be possible to extend communications between the two blocks (and all four devices) using an interface such as a microcontroller of some sort.  

My questions:
Are my assumptions regarding the lack of connectivity between the two blocks correct?  [I think so, based on interconnection details in the manuals]
Has somebody built such an interface already?
Is there information available on message passing and protocols between the K3 and [KAT500/KPA500]?  The K3 is used as the reference, as the KAT500/KPA500 are designed to tightly integrate with it.
Same protocol question for the KX3/KXPA100.

Essentially, what I would be looking to do is to use a microcontroller to emulate a K3 in order to talk coherently to the [KAT500/KPA500] block.  Then the other side of this interface would talk [KX3/KXPA100].

My apologies if this a RTFM question or documented somewhere, but if so, I could not find it!

Kevin VE7ZD

"where the second block [KAT500/KPA500] utilize essentially BCD for band data and an ?AUXBUS? signal that I have not yet found out much about."

You can fully control the KAT500 and KPA500 using their serial interfaces without needing AUXBUS and without using the 4 discrete band interface.    I'm doing exactly that with my Kenwood TS-590/KAT500/KPA500 controller.

Start by reading KAT500 Serial Command Reference.pdf and KPA500 Programmers Ref.pdf.

I  have no knowledge of what data is available from the KX3/KXPA100 but if you need help with KAT500/KPA500 control I'll be happy to share what I know.

Oh pshaw.? That is quite a stretch, and I do not see it, myself. Other 
than the basic shape (a rectangular box)? and handle brackets (which I 
think are optional on a KS3,)? it does not look like a KX3 (not to me, 
anyway.)? Besides, several other QRP rigs have that same basic shape.?? 
The screen bears no meaningful resemblance, and it consumes most of the 
front panel.? You are working to hard? for some reason.

Just MY take.?? Your mileage may differ.??? K8JHR

This is nothing unique to the KPA1500: ALL class AB amplifiers behave 
this way. Even an "ideal" class AB amplifier has a maximum dissipation 
at around half of full output.

One thing running at lower output probably will buy you is lower IMD.

Totally aside from the power meter issue, what you are doing with the 
ATU is like loading a tube amplifier more lightly with the PI network. 
Lighter loading will improve efficiency, but may result in more 
distortion. One reason solid state amplifiers are generally less 
efficient than tube amplifiers is that transistors (including FET's) 
become extremely nonlinear when they are driven close to saturation. 
That is, when the voltage across the device is near zero at the bottom 
of the cycle. As a result, solid state amplifiers have to be loaded more 
"heavily", to keep the transistors far from saturation. This, of course, 
results in more dissipation.

I haven't tried it, but it's possible the KPA1500 could be loaded more 
lightly by manually adjusting the ATU values to improve efficiency on CW 
or RTTY, where linearity isn't a big issue. That might reduce PA 
temperature a little, though I'm not sure it would be worth the trouble. 
Given how sensitive the KPA1500 is to small changes in SWR, though, 
setting this up across a band would be a tedious process.

The rather large variations in PA current I see at 1500 W output at a 
moderate SWR, like 1.3:1, is probably due to the same effect. (A 1.3:1 
SWR could be a load impedance of anything from 39 to 65 Ohms.)

Hi Andy:

Thanks for the suggestion.  Using the computer would let me control the KAT500 and KPA500 for sure, but what I am looking for is seamless band tracking and antenna output tracking between the rig (in this case KX3 and KXPA100) and the [KAT500/KPA500] block.

If I can interface the [KX3/KXPA100] combo to the antenna/tuner, then there would be full, seamless integration as there is with the K3.  That?s the goal.

73,

Kevin VE7ZD

"If I can interface the [KX3/KXPA100] combo to the antenna/tuner, then there would be full, seamless integration as there is with the K3.  That?s the goal."

 I believe I have achieved a level of integration of KAT500/KPA500 with my TS-590S that exceeds the integration available with the K3.  My controller is hosted by an Arduino Mega 2560.  No PC involved.

Whether you could do what I have done depends on what data is available from the KX3.  The basic functionality of my controller relies on reception of Kenwood format IF, FA, and FB.  The controller uses these parameters to compute appropriate KPA500 ^BN; commands and appropriate KAT500 F; commands. That is all that is needed to set the KAT500 and KPA500 to the correct frequency.    Enhanced control features require a more extensive data set.

Using the K3 Utility be sure the filters and modes are correctly 
selected.? For AM you will need either the 6 kHz or 13 kHz active and 
set one of those for AM mode for TX and RX.

In general, RF power gain stages (the tubes or transistors) are designed 
to work at some designed power level and impedance. Pi and Pi-L networks 
in tube amps provide both harmonic filtering and impedance matching. In 
most solid state amps, the output network provides only filtering, and 
are designed to work into 50 ohms.

K6XX, one of the Elecraft engineers who works on their power amps, gave 
a talk to our contest club stressing the importance of providing a 
matched load to the output devices, and to the output itself. He 
observed distortion increases significantly when that condition is 
satisfied, whether it is an antenna tuner for a solid state output stage 
or the Pi or Pi-L in a tube amp.

I don't know, but you could ask K4XU, who designed the Ten Tec power 
amps and later the RF circuitry in Alpha amps. He told me the 87A was 
his design (although he made it clear that he did NOT work on the 
control circuitry).

Just a reminder to Canadians running the KPA1500 or any other full power
amp in the contest this weekend.

Max RF out is limited to 750 watts (not our usual 2250w PEP for SSB).  Only
CW and SSB get to go above 750 watts.

Kevin,

While that may be an interesting exercise, it only takes one dit for the 
KPA/KAT500 to sense the frequency and react accordingly.
The only thing missing is the ability to track the VFO frequency during 
receive.

73,
Don W3FPR

Good Evening,

 ?? The bear berries are getting ripe.? That means the grouse will soon 
be out.? The hot weather in the middle of the week excited the spiders 
into a frenzy of orb spinning.? Always around face level.? Once you 
clear a trail you may have twenty minutes before there is a new one.? 
The last of the huckleberries are tart and refreshing.? I shake the bush 
to remove the overripe specimens and store the others in my mouth.

 ?? Conditions are a bit more noisy due to the gust of solar wind 
earlier in the week.? But as long as it is not really noisy the extra 
ions help.? High temperatures also kept me from bucking that large log.? 
This will help my sending.? Using a chainsaw detracts from my fine motor 
control.? It takes a couple days for the buzzing to stop.

Please join us on:

Well, it IS some significant competition, especially since the "PX3" is built-in eh?

Oh pshaw.  That is quite a stretch, and I do not see it, myself. Other than the basic shape (a rectangular box)  and handle brackets (which I think are optional on a KS3,)  it does not look like a KX3 (not to me,
anyway.)  Besides, several other QRP rigs have that same basic shape. The screen bears no meaningful resemblance, and it consumes most of the front panel.  You are working to hard  for some reason.

Just MY take.   Your mileage may differ.    K8JHR
