Re: [Elecraft] 270 foot (ish) Doublet & K3 ATU

[Rick Bates]

I'll restate:  The length of coax should be as short as feasible because the 
losses from mismatch (SWR) are highest when compared to window or ladder line.

The shortest distance from my rig to the choke is about ten feet unless I bring 
the window line inside (too problematic) or put the rig in the window next to 
the choke (won't happen).  That is what I use, ten feet of coax; the shortest 
possible piece, for me.  Ideally it should be much shorter. 

I most carefully explained (rather than presuming an understanding and trying 
to be more clear) in the last note that adding 30' of window line resulted in 
different tuner values, but no change in the band segments where I could 
operate at reasonably low SWR ergo no significant (cumulative) change at the 
rig (I was still band segment limited, same places).  On some (20M and up) 
bands, retuning was not required; it's simply two 'long wire' antennas in 
phase. 

Empirical evidence is neither right or wrong.  It may bring more questions than 
answers, but it can't lie.  The tuner likely compensated for the slight change 
in the feed, the antenna elements were unchanged and the end result was no 
effective change. 

Changing the coax portion length of the feed changes everything dramatically; 
the tuner values, the losses, lowering the SWR to give me ability anywhere 
160-10.  But I don't want the line losses above 40 M; it gets worse quickly 
above that.  I only add that section in when home, I'm DXing and QRO. 

In this case, my findings may go against standard beliefs, but stands as 
evidence nonetheless. 

When I move the shack upstairs and replace the window line (the single strand 
solid copper elements make me nervous) I'll be sure to have an analyzer to make 
more careful measurements.  In the meantime, my 'wrong' system is working.  

Why wrong?  No part of the system (antenna or feed) is ham band resonant, which 
is why:

It's natively high in SWR;
A tuner is required;
It works on all bands (the KAT3 tuner loves it, the KAT500 under QRO, not so 
much on 160/80);
Any system change may give unexpected results. 

It's at a point where it works on all bands about as well one can expect for a 
simple wire dipole; more so considering the lack of height.  Over 200 countries 
later, I have to say it's working. 

However, I miss my tower and beams...  They're more effective and easier.  Next 
house I'll get them back. 

I hope this answered your questions and concerns.

[Elecraft] K2/100: Power Control Defective

[Richard]

A fellow ham is having the following problem withhis K2:

A year ago, we installed the KPA100 which worked fine until recently.

Suddenly, the TX Power Control failed and the K2 will deliver either 
9-15 W or - with the 100W PA switched on - up to 150 W into a dummy load.


I suspect there is an issue with the TX-ALC, but no defective diode was 
found.


I personally don't own a K2 but is there a TX gain calibration procedure 
similar to the K3?


Suggestions welcome - thanks in advance.

Re: [Elecraft] K2 #6951 "It's Alive!"

[ke9uw]

I took about 10 years to finish mine. I started it, put it aside and then saw
lots of mods and so forth, so I noted them and fit them into the
instructions. When I finally got back to it, I didn't have to unsolder
anything to fit the mods in. I did have to toss a firmware chip that had
never been installed in favor of a newer one that I ordered also.
It all worked when done! All the options installed but the 2M and the 100
watts.

Re: [Elecraft] KX3 and KAT500

[Dick Dievendorff]

Phil:

The KAT500 is not a QRP antenna tuner. The SWR bridge's voltage divider is
designed for the 500 to 1500 watt range.  At QRP levels the SWR bridge
voltages (and voltage differences) become quite small.   As reflected power
drops near zero, it becomes difficult to measure small SWR differences. It's
very difficult to find a minimum SWR when the ADC jitter exceeds the change
due to a different tuner setting.

We have a couple of antenna tuners designed for lower power: The KAT100,
KAT3 and KXAT100 are all 110-watt tuners. The T1 and KXAT3 are 20-watt
tuners.

But the KAT500 should be able to select from pre-tuned solutions (what I
have called a "memory recall tune") at any transmit level that is high
enough for the frequency counter to work.  5 watts should be plenty.

A "full search" tune is problematic at low power levels, particularly as
exciters fold back (reduce output power) when asked to deliver their maximum
specified output power into a varying SWR load during tuning. 

10 watts from a K3/100 is not difficult.  10 watts from a KX3 into a varying
SWR load is more difficult.

You're correct to bypass the KXAT3 when using an external tuner.

Subject: [Elecraft] KX3 and KAT500

I have been experimenting with my KAT500 and the KX3.  Although I do have a
K3 and KPA500 configured with the KAT500 using the switched arrangement
described by the KE7X KX3 book, the K3 is powered off and the KPA500 is in
standby mode during these experiments.

Although the KAT500 user manual says that to start a tune cycle, at least 10
watts needs to be provided.  So, my KX3 is right on the border line and from
my experience in this setup, it DOES NOT initiate a tune cycle in the
KAT500.

Has anyone else been successful in initiating tune cycles for the KAT500 at
10 watts from the KX3.  My method is to VFO to the desired frequency, make
sure that the KAT500 is switched to the right antenna, and then key down for
tuning.  Note: I do not make use of the KX3 built in tuner (I am assuming
that I should not given I have a low SWR to the KAT500).


Also, given that my KAT500 is totally programmed across the bands for my two
antennas, will the KX3 provide enough power (at 10 watts or under) to
initiate the memory lookup for a tuned segment (I have programmed each 20
KHz segment on 80 and higher frequency bands using my K3).  Is 5 watts
supposed to be sufficient for locating the proper memory stored tuned LC
parameters?  I have not found this to be so (but, here I am not positive of
the starting conditions and may need to do this test over, it was getting
late last night).

Thanks for any help you can be.

Re: [Elecraft] It's the 21st Century Guys! PS2 is DEAD

[Joe Subich, W4TV]

My apologies to Eric posting on a closed topic.

However, the thesis that started this is wrong.  PS/2 is but one
implementation of I2C bus technology and the I2C bus is still very
much alive in many control systems.  A great many of the general
purpose micro controllers contain dedicated I2C ports and for that
reason support for PS/2 is essentially "free".

Re: [Elecraft] Fwd: KX3 kit: No CE badge for self-built KX3s?

[David Cutter]

I'm being picky, but strictly speaking kits are not required to have a CE 
mark which has EMC as a part of it requirement, not the other way around. 
However, stating the obvious, that doesn't absolve a user of from creating 
EMC issues with other equipment outside his premises.

Re: [Elecraft] uhf connectors

[kd7gc]

For what ever it might be worth, I use 7/16 DIN connectors instead of either
UHF or type N connectors.  Once I have connected a jumper to the back of a
rig, I then use only 7/16 DINs all the way to my SteppIr.  My DB36 also uses
a 7/16 DIN as I use a custom balun from Array Solutions.  I had Jay make my
balun with a female 7/16 DIN, just as I had him build my PMII couplers with
male and female 7/16 DINs.

Re: [Elecraft] K2 #6951 "It's Alive!"

[David Pratt]

Chuck  -  It's good to know that the K2 can take anyway between one week and 
ten years to build.  I am sure it was worth waiting for and you will get lots 
of enjoyment with it. Of all the Elecraft kits I have built the K2 gave me the 
greatest pleasure and satisfaction.  Incidentally, there is not a 2m option for 
the K2 unless you mean the 5Mhz/Xverter interface.

Re: [Elecraft] Fwd: KX3 kit: No CE badge for self-built KX3s?

[John, 9H5G]

Being picky then I cannot see how you can infer what you have written from 
the regulation.
 "For the purposes of point (c) of the first subparagraph, kits of components 
to be assembled by radio amateurs and equipment made available on the market 
and modified by and for the use of radio amateurs are not regarded as equipment 
made available on the market."  
 My original text stated clearly that "Kits are not subject to the EMC 
requirements" which is what the document is about. 

A responsible ham will of course act responsibly in all manner of ways 
including EMC but that is not what the OP asked. 

We're not all lawyers here. We take the written word in good faith ham-to-ham. 
This is not a place to be picky - rather, it is a place where we accept the 
inferred meaning from others in good faith. Far, far, far too many threads have 
been closed as they have degraded into 'pickiness'.

Hello John,

thanks for this hint!

You are right: Article 2 paragraph 2 states this out. So my self-built
KX3 is legal to use since it is handled like any other homebrew gear...

Re: [Elecraft] Fwd: KX3 kit: No CE badge for self-built KX3s?

[David Woolley (E.L)]

Although Elecraft may get away with it, a lot of equipment that is CE 
marked has final assembly stages that have to be done after unpacking 
the box.   I don't think the  EEC exemption was designed to cover the 
final assembly of dedicated sub-assemblies, but rather assembly from 
commodity parts.

That may be David but its much more EMC friendly which was your original
tack.

As to your comments on 'intent' thats hardly a topic for here. Best talk to
the European authorities on that one.

But this isn't a general topic forum. It is an Elecraft forum.  And guess what.
Elecraft is the owner/moderator.  People aren't here to chit chat about whatever
is on their mind, unless it relates specifically to Elecraft equipment.

[Elecraft] Weighted Knob - K2 - For Sale

[richardscott w]

I bought the updated K2 Knob from the 73CNC guys at Dayton, so I have
the prior model (without the ball bearing dimple) available for sale.
Its in perfect condition, and is a very nice enhancement over the
stock tuning knob. I can send a picture upon request.

A K2 knob can work great as a VFO B knob on the K3.  You have to ream it out a

Re: [Elecraft] [K3] Hum JT65/JT9 and Vox. Resolved.

[Larry Lopez]

So I decide to give up and set the audio level right.
So I get the free for private use sound card oscilloscope
http://www.zeitnitz.de/Christian/scope_en.

I picked this one because it was first when I goggled "sound card
oscilloscope".

Very nice.

But gee, there are 2 channels for the mike and a balance control.
One channel has "the signal" one channel has "chaff".

So I set the balance control to kill the "chaff".
I then raise the volume in the K3 line out until it flat tops
and I back it off by 2.

next step, get it to sample at 48000.

obsessive, I am.

Re: [Elecraft] [K3] Hum JT65/JT9 and Vox. Resolved.

[Rick Bates]

The gain of the sound card  (the volume) can be changed by the driver so even 
if the K3 output doesn't change, the levels can still change. 

I leave the software (driver) maxed out and the K3 Lin Out at 1 (almost off), 
but this risks swamping the card AGC so I use the K3 filters to limit what the 
sound card gets.

Re: [Elecraft] KX3 supplemental heat sink offering

[fredem]

This morning two matters were brought to my attention, that require your
input to give me direction:
1. The matter of Cooler KX color in summer deployments especially in very
warm areas like Texas, Florida, the Mediterranean countries. I have already
manufactured prototypes of a Cooler KX-T for tropical, desert, and any other
high heat environs. The question that was asked this morning was whether I
would consider offering the heat exchanger in White Powder coated finish. It
depends on your response whether this could fly. Who would order a white
heat exchanger? as an alternative, would a flat plate machined to fit the
mounting holes be of interest? This could be coated white. In addition to
shading the heat exchanger, it would change your open fins into a ducted
design further improving the heat removal by slow low pressure convection.
It would be removable for show and tell.
2. I was asked to see if there was interest in having me provide custom cut
GapPad heat transfer pads for those of you who dislike heat transfer grease
as much as I do.
You may discuss this on the forum and also email me directly. Thanks, Fred,
VE7FMN

Re: [Elecraft] It's the 21st Century Guys! PS2 is DEAD

I'd prefer that, as well.  I might have an old 19" FP monitor around 
here somewhere that will still accept a SVGA connection.


If I were to buy a new monitor for that purpose, it would certainly have 
HDMI support, and it wouldn't cost that much, either.


All three computers in the house, including the one in the shack, use 
HDMI cables, as does the satellite receiver/DVR box and the DVD player, 
connected to the big-screen TV.

these days.  I have not bought the P3 SVGA option for this very reason.  
Actually, there is another possibly more important reason -- I have no use for 
a larger display screen on my ham shack desk.  But, the lack of either DVI or

[Elecraft] Combiner for 2x KPA500?

[Jim Miller]

I saw someone joking about such a thing but how difficult would it be to
implement?

I'm tapped out on antennas in my restricted location so if I wanted more
reach, more power would be required. I am working a bit more on optimizing
my receive antennas for low bands.

I'm sure I'd lose some automation unless Elecraft provided some firmware
mods to let two amps track the K3.

I'd use it on resonant antennas so the KAT500 wouldn't really be needed.

Thoughts?

[Elecraft] FS: Small monitor used with a P3

[Tim Cook]

I have a small external monitor that I used with my Elecraft P3. I sold the 
K3/P3 combo and was going to keep the monitor for future use but decided to 
sell it. It is less than 2 months old.
It worked great for my particular installation, I had limited space and didn't 
have room for a full size ext. monitor. This fit the bill just right. Here are 
some specs.
10.4 inch TFT LCD Monitor
AV1/AV2/VGA/Audio/Touch screen
Resolution: 800x600, 1024x768, 1600x1200 RGB
12vdc (cord not supplied) or 120vac with supplied adapter
Has a remote to control inputs, menu, vol, modes
VGA input, USB input (comes with both cables)
I paid $150 for it, I will ship and insure it for $110 in the US.
Paypal or Postal Money Order.
Thanks

Re: [Elecraft] KPA500 Combiner

Don't forget that not only do you need a combiner on the output,
but also a splitter for the input.

A couple of dB here and there and you soon lose most of that gain you got.

Better yet, look at the SPE 1.3K-FA.

Re: [Elecraft] Need Audio for SignaLonk from Sub-Rx on my K3

[Don Wilhelm]

Bob,

You cannot tell the K3 to change it.

The Signalink is a mono soundcard and only listens to the left channel - 
which is the connection to the tip of the jack.  Even if the Signalink 
cable has a stereo plug, there is nothing connected to the ring.


If you need to listen to the SubRX audio, you will have to use a 
soundcard that is stereo.
If you use the internal computer soundcard, be sure to turn off Windows 
sounds.


If you want to use the Signalink, you would have to make an adapter for 
the Signalink audio input so that the audio is taken from either the tip 
(normal) or the ring connection (SubRX) - a manual switch would be in 
order to select either one.

to the Sub-Rx because I shut off the mast mounted Gaasfet and although
the sub-RX audio dropped way off, the JT65 program showed a steady,

So how do I tell the K3 to put the audio from the Sub Rx and not the
main Rx?

Bob,

Before attempting to use the EMU-0404, check your application.  If it 
cannot select between the left and right channel inputs, then you may as 
well continue using the Signalink and switch the channels manually as I 
suggested in my prior email.

I do realize the Sub-Rx audio is split when listening thru the headsets.

Re: [Elecraft] CW on SSB

[Don Wilhelm]

The real answer here is that the K3 always indicates the carrier frequency.
There is no shift on SSB.
When changing from SSB to CW, the receive frequency is shifted by the 
amount of the sidetone pitch.
The result is that the CW signal is now at an audio frequency of zero, 
which neither your ears nor the K3 audio stages can detect.


The K3 does have a CW in SSB menu setting that modifies that behavior 
and will allow one to send CW while in SSB mode.

Is there something that I'm doing wrong to not be able to copy them on CW?

Re: [Elecraft] Help With K2 SSB Audio

Larry,

One thing to try is to tuck the ribbon cable and speaker cable to the 
KPA100 up into the space between the top of the Control Board and the 
KPA100.  Remove the right side panel to easily do that.  The object is 
to route those wires as far away from the KSB2 board as possible.

Hi All,
I am looking for some suggestions on troubleshooting an SSB audio problem with 
my K2 (Ser # 495). With about an hour to go before the end of the W1AW/1 CT

first I blamed it on the fact that the calling station was well off my transmit 
frequency. When a second caller also mentioned bad audio. I asked him to tell 
me more. He thought it sounded like a bad mic or something, so I swapped out my 
Heil Gold Line mic for my Heil headset. No difference. Then I went to the 
Kenwood hand mic that I use for casual operating. Again, no difference. Since 
he also seemed to be a bit off my frequency, I tried tuning him in with RIT. I 
realized I could not tune him in for clear received audio, either. So clearly 
my K2 has developed a problem.
I imagine it is something in the KSB2 SSB adapter. Any suggestions as to what 
might go suddenly wrong with the adapter? Or other suggestions as to the source 
of the problem?

Good method, BUT -- better to drop the level by half the voltage from 
the "flat top" point. That's because the distortion of many (most?) 
computer sound cards drops by 10 dB or more at half their maximum output 
voltage.

[Elecraft] I survived Dayton 2014!

[Slava Baytalskiy]

Hi everyone!
Got back from Dayton today.
First time there. What an event!
I just wanted to mention the following:
no other HF radio-selling booth was as busy as the folks at Elecraft! Not by a 
long shot!
Made me very proud to own one. I saw the jealous looks every time a K3/KX3 was 
mentioned during Rob Sherwood's presentation (Contest University).
I did order my KPA500/KAT500/W2 kits so my K-Line is pretty much completed 
(once i receive/assemble them all).
Got a lot of valuable info from Wayne. Met Lisa and Eric. What an amazing 
bunch...

Anyways, thanks for making these awesome products!!!

Re: [Elecraft] I got big heavy knobs...

[Don Wilhelm]

David,

The bearings in the encoder should be able to handle the added weight of 
the knob.
However, there is one caviat - some users of that knob want to mount it 
with no drag on the knob so they can "spin" it.  That means that there 
is no contact with the felt washer, and the weight of the knob is like a 
heavy lever placed on the end of the encoder shaft which would have a 
tendency to bend the shaft.


If the knob is mounted so there is adequate contact with the felt 
washer, the knob will be supported and should not cause any problem.


Bottom line, position the knob so there is normal drag produced by the 
felt washer.

Is this a valid worry?  If you are using these knobs, how long have you
had them on?

Re: [Elecraft] K2/100: Power Control Defective

[Don Wilhelm]

Richard,

The K2 (and K3 and KX3) control power using a closed loop system. That 
means there must be some means of measuring the actual power output 
right at the antenna - that measurement is compared with the power 
requested by the power knob in the MCU, and the drive is adjusted as 
required to make the actual power output match that requested.


Now consider what would happen if the wattmeter at the output of the 
KPA100 were not functioning properly - there would be low or zero power 
reported to the MCU and the MCU in turn would try to increase the power 
to bring it up.  Of course, even at maximum power, the MCU would still 
think there is no power being produced.


Bottom line - there is something wrong with the wattmeter in the KPA100.
The first suspects are diodes D16 and D17.
Secondary suspects are U5 (not likely, but possible) and U6.  U6 does 
sometimes fail for reasons unknown, but do check D16 and D17 carefully 
(or simply replace them) because that is the most common cause of 
wattmeter failure.

A fellow ham is having the following problem withhis K2:

A year ago, we installed the KPA100 which worked fine until recently.

Suddenly, the TX Power Control failed and the K2 will deliver either 
9-15 W or - with the 100W PA switched on - up to 150 W into a dummy load.


I suspect there is an issue with the TX-ALC, but no defective diode 
was found.


I personally don't own a K2 but is there a TX gain calibration 
procedure similar to the K3?


Suggestions welcome - thanks in advance.

Re: [Elecraft] I got big heavy knobs...

[Slava Baytalskiy]

Thats exactly how i did it. I'm actually using both felt washers on the VFO A 
and one on VFO B.
I have the regular (all black) knob set from 73cnc.com (couldn't wait till 
Dayton to get the deluxe).
But they are great.
Did you know these guys picked up the K8RA's keys business?
I just got my P4 iambic from them on Saturday at Dayton.

Re: [Elecraft] K2 #6951 "It's Alive!"

[Don Wilhelm]

Chuck,

WHAT!  K2 SN 6951 was kitted much less than 10 years ago, and had 
already been updated with ALL the Elecraft mods.


Also, what 2 meter option for the K2?  The K2 does not have a 2 meter 
option.  If you want 2 meters, one must use the XV144 transceiver.


I hope you did not replicate mods that were already installed on the board!

OTOH, if you were updating a much earlier kit (original serial number 
less than 3000) and you purchased the upgrade kit with new boards, then 
all may be OK (those upgrades were issued a new serial number) - all you 
needed to do is build the K2 using the newer manual.

never been installed in favor of a newer one that I ordered also.
It all worked when done! All the options installed but the 2M and the 100
watts.

[Elecraft] Question about the KX3

[Joshua Gould]

So I'm thinking about ordering a KX3, and adding on the antenna tuner.  I
see that the microphone is listed as an accessory.  Is the microphone
included in the kit, or is it an "optional" item?

The more I learn about Elecraft, the more I am leaning toward the purchase
of a rig in a kit that I can build...

Re: [Elecraft] Question about the KX3

[Matt Zilmer]

Hi Joshua,

I recommend the ATU.  Very handy for wire and vertical antennas in the
field, and for non-resonant antennas at your home QTH.

The MH3 (shown as H3 on the KX3 page) is an accessory, but not
included.  You would have to order it separately, as with the ATU.

Many KX3 ops prefer the kit.  Building the kit shows you how the KX3
fits together and there is an excellent theory of operations section
in the owner's manual that you should read.  It's a good idea to know
your equipment inside-out, imho.

I own and operate an early KX3, and its performance constantly
surprises me, especially in field conditions.  I use the KX3 (mostly)
away from the home QTH.  However, it is a full-featured and very
capable base station rig as well.

See http://www.sherweng.com/table.html for the KX3's receiver ratings.

Re: [Elecraft] Question about the KX3

[Don Wilhelm]

Joshua,

In keeping with the Elecraft philosophy of not requiring the customer to 
purchase any more than is desired, the KX3 microphone is an "optional" item.


Certainly a microphone could be provided with every KX3 if the price 
were 'bumped up' by the cost of the microphone.  But that is not "the 
Elecraft way" - if the customer does not want the Elecraft microphone, 
he does not have to pay for it - that fact requires that it be an option.


You will find the KX3 easy to build from the kit - just follow the 
instructions in order.  If there is something you do not understand, ask 
on this reflector and you will likely receive a prompt answer. For those 
questions not easily answered by other owners on the reflector, an email 
to kx3supp...@elecraft.com should provide you with an "official" 
response that will answer your question.

Hi Alan,
What is a good source of the 7/16 DIN connectors in the US?
