Hello,
There is a new version of Win4K3Suite available, version 2.018. This release
improves the entity lookup from ClubLog as well as other minor items.  You
must download this before the end of February.

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

Subject: [Elecraft] K3S relay noise when using Rx ANT IN port
Message-ID: <1580595677249-0.post@n2.nabble.com>


My K3S is configured to use the RX ANT IN port for a separate Rx antenna.
However, on SSB transmissions I can hear an internal relay operating in
synchronism with peaks in transmit power.? I assume this is a relay in the
receiver input protection circuit?

Is operation of the?relay in this manner normal? Apart from finding the
noise rather irritating I am concerned about the reliability of the relay
when it is called upon to operate so many times during a QSO.

The Tx and Rx antennas are about 10 metres apart and I am transmitting 100
Watts.

Thanks for your help,

Ray

That is indeed the protective relay on the RX Ant port. You should find a
way to protect the RX Ant port from your TX signal.

There are many products in the market for his purpose. Not sure of the best
choice on your side of the Atlantic.

Ray,

Your transmit signal is getting into your RX antenna with more energy 
than is safe for the K3S.  10 meters is not much separation unless the 
antennas are oriented so one is not in the null pattern of the other.

Using antennas that are of opposite polarization (such as a horizontal 
dipole and a vertical) may be OK for a 10 meter separation, maybe not.

There are protective devices available that will disconnect the RX 
antenna when the K3S is transmitting, and use of one of those may be the 
quickest and easiest solution.

I use a surplus coax relay, one with BNC connectors, and it is triggered 
from the KEY OUT function on the transceiver along with the 12V 
source.?? Be sure and use a diode across the relay coil to prevent back 
EMF.?? The relay switches the RX ANT port to a 50 load, being a resistor 
mounted in a BNC connector on the N.O contact port.? The common relay 
port goes to the radio? RX ANT IN and the N.C. relay port goes to the 
transceiver RX antenna. It only clicks when the PTT is active and 
released.??? As to CW, well that's another issue where the relay needs 
to be held in during transmission or you'll hear it with every CW element.

I personally would be concerned about using solid state switching 
devices in as much as a junction when saturated may be prone to produce 
harmonic related energy.?? However, there are circuits which use PIN 
diodes or JFETS, designed correctly, would likely be clean.

I would cease operating with the RX antenna connected immediately  
before you damage your transceiver. 10m antenna separation is very  
close. I has a similar situation at my P40A station so I shorted the  
RX coax with a relay during transmit.

I had similar issue. i used a 3.5mm to 2.5mm audio cable (each end three
segment), from a Yaesu SCU-39 cable kit I was not using which looked perfect
for the job. 

However it turned out the centre segment was not wired, with same results as
above. Initially I thought my line-in was possibly not stereo on rear of my
Dell PC as it is a combo pink/blue mic/line in jack.

Found a stereo 3.5mm cable and luckily a 2.5/2.5mm adaptor for one end.
Looking much better, the display better than any of several others I have
tried incl non free.

I have found the Omni-rig cat control a little buggy sometimes, losing mode
control, and freq readout offset.
Re; setup and restart seems to get it back good.

Early days, and I think i just need more practice. I am using a realtek
sound card at the moment set 192KHz, and have ordered an ASUS Xonar U7 and
an stereo isolation lit with audio lines.

I would like a PX3 , however not at current pricing, and looking at a used
unit if some one is selling.

Gordon,

I am a brand new owner of a KX2, specifically purchased for POTA activations where I cannot just drive up and unload the ?big? rig (which happens to be a fairly small but heavy  FT-857D setup). I?ve had the KX2 with me on a recent trip to Florida and I activated three parks on SSB/PSK31. I used a SOTABEAMS 6m telescopic mast with a SOTABEAMS Bandhopper Midi. The ATU in the KX2 had no problems at all tuning the antenna. It?s a great POTA setup. Let me know when you?ll be out activating, I?ll be listening for you.

Message-ID: <CADkB6UocfRqJNqq9dBNppMQV7OYX_YLxRzxHZhJj1P0HeOxqEA@mail.gmail.com>

Hoping someone has a suggestion for how I can work around some local QRM.

I have a kx3 with filters installed
I have wsjtx running.
I've recently added a px3 to see if it would help provide insight.

I find intermittent broadband noise that desenses my receiver on multiple
bands. 1) It appears to either be On or Off, no visible fading.
(Transitions are <<1 second). Sometimes a little flickering but usually
extends for minutes to hours.
2) When on, signals in waterfall completely disappear or are reduced to
just a couple nearby (loud) stations
3) when on, it wipes out at least one whole band (usually 20m, sometimes
40m as well).
4) when on, the full 200khz slice in px3 goes green snow
5) still happens if I throw breaker in my subpanel and am running off of
batteries
6) with 30 min of fiddling, haven't been able to see it in a kiwisdr node
less than a mile away
7) pskreporter still shows me to be getting out (to the extent I can)

Broadband, no visible peaks, so not sure I could triangulate it by
wardriving with a Kerberos.

Any suggestions?

Is there a way/practice to maybe leverage the filters to increase rejection
of the interference?

Thanks in advance,
Scott

I am running WSJT-X in FT8 mode on my K3S using the onboard sound card and USB cable and VOX for keying. My computer is a Mac running Catalina. The K3S manual recommends setting the drive at 4 or 5 bars to avoid distortion by the ALC.. When I use the audio output slider set the drive level, the display jumps from no bars to 6 bars, and vice versa, and nothing on between.  I have also tried using the MIC level and the POWER slider in FT8 with the same results.  The software id decoding fine. Can anyon suggest what the problem might be?

An absolutely classic problem, I am the first to respond I am assuming only because the Super Bowl is on!

I call this the "gain chain" problem.  It depends a bit on how you are set up but try the following.  Go into the menu on the K3S and turn down the LIN OUT value.  I have mine set at 2 I believe.  Once you do this you should be able to more finely control the drive level.

This is likely to fix your problem at once.

Go into the TX TEST mode and see if the issue still exist. If not, it?s an RFI issue. If not, back the MIC (Line gain) down to zero and start up watching the ALC  scale. The computer level may be overdriving the radio. If so back the PWR slider on WSJT down.

YES,

I am using a KX3.?? I use the "bar" on the right and set 20db of 
attenuation in the audio drive "chain".
Mike gain is now set at aprox 40, rather than 3-4 (one step makes a BIG 
step)...
I can set "ALC" correctly.

Playing with my v5.24 HRD, it all works well with the KX3 under the K3
profile, apart from activating the ATU which doesnt work with ATU or Tune
buttons.

Has anyone modified the program cat control to do this if they could share
please, thankyou.

Good Evening,

 ?? Twenty meters had a little noise and mild QRN.? I had to move the 
net after a loud CQ started up on net frequency.? Guess they could not 
hear me.? Forty meters lasted longer than normal.? With the extra 
daylight I was able to work into Southern California. After I closed 
with W8OV I heard someone calling him.? I waited and then worked KO6WL 
at ESP levels.? It took a number of repetitions but I got the call one 
part at a time.? Even without an active sun signals were fair.? From now 
until the time change forty meters should work well for us with the 
longer days.

 ? On 14050.5 kHz before 2200z:

W0CZ - Ken - ND

NO8V - John - MI


 ? On 14050.75 kHz after 2200z due to QRM:

K6XK - Roy - IA

K4JPN - Steve - GA


 ? On 7047.75 kHz at 0000z:

KG7V - Marv - WA

W0CZ - Ken - ND

K6XK - Roy - IA

K0DTJ - Brian - CA

KL7CW - Rick - AK

W8OV - Dave - TX

KO6WL - Howard - CA


I was able to work a few of you before each net which helped.? I did 
catch an F at the end of the first call up on 40 meters.? I tried 
calling WM5F, Dwight in Idaho, but the window had closed.

Happy Ground Hog's Day!

First cut the output from the computer by 1/3 to 1/2.  Now this will allow finer adjustment with the K3 controls.

All resolved below, so please disregard sorry... I feel a bit lazy

for not trying a bit harder before my previous post. Of course adding a 
custom SWT44

cat command to macros and adding the button in layout turned out 
reasonably simple.

I switched to using HRD dde control with HDSDR instead of omni-rig cat 
control.

Lee,

In addition to the MIC Gain and the WSJT POWER slider (misnamed because 
it is just another audio level control, you also have to deal with the 
computer soundcard audio level.  It should be set for Line Level instead 
of speaker if that is possible, and that is one of the 3 audio controls 
that you have to manipulate.

Go to my website www.w3fpr.com and scroll the left column to the last 
article and click to see the article dealing with this problem.

Well, it sounds like it is something outside your QTH. Unless you have some
solar charge controllers for off grid power, or some other possible noise
maker. Maybe go mobile in the neighborhood when the noise seems to be on
for a while. If you have a directional antenna you might be able to get a
vector that way.

Scott,

It would appear as though you are receiving noise from somewhere.  Your 
steps have eliminated your house, but your neighbors may be the source.

I don't have an easy answer, but I don't think it is in your KX3.  To 
test, does it occur if you connect a dummy load?  If not, it is coming 
in on your antenna.

Filters and NR and NB are not likely to tackle it adequately.  You will 
have to locate the source and send a notice to the FCC for action.  You 
can use the KX3 portable with a short antenna to try to localize the source.

Sounds like the interference from "grow lights" that have been reported 
in the past.  Are any of your neighbors starting gardening plants or 
growing pot under UV Grow Lights?

Don W3FPR

It is much like what I recall when the hydroponics shop was still in
business a couple blocks away. But in that case the source was never on
less than 15 min at a shot.

Part of what is maddening about current is that duration is completely
random, seeing blips during ft8 turnarounds, followed by blocks of 30 min
solid hash, 5 min free, completely unpredictable. I can get ft8 cycles to
complete *just enough* to not rage quit and shut the radio off.

And 15/30 seem less affected than 20/40, which is Confusing. Since the
whole band goes I wouldn't expect it to follow that sort of harmonic
behavior.



What would a 20m spark gap transmitter look like on modern gear?

Hm. And as soon as I send that I check, and 15/30m has 15dB of odd surging
over a 1-2Hz cycle. Maybe it really it taking everything out

Yeah, all bands.  Then suddenly clears, signals sprout all over the
waterfall and are promptly silenced once more.

In any case, doesn't sound like there's any particular Elecraft filtering
wizardry I can engage.

Given that they've repeatedly slipped K4 dates, now wondering if I should
cancel my K4D.

Thanks for the feedback, everyone.

Dany,

it looks like the RX-FES (KD9SV) and AS-RXFEP (Array Solution) protection
units combined together... isn't it ? :)

Are you using it in SO2R or Multi-Multi config?

A possibility is an ionospheric sounder ...

In the past there were many hundreds of 'em operated by "everyone".

Used to be plagued by one a few miles north of Denver.  Another was located
behind the NBS in Boulder.

Give Google a peek ....

I'm somewhat surprised Elecraft don't just flip that relay into the
"protect" position whenever the radio Transmits.

Or at least have a menu option for that relay's behaviour, that defaults
to the "Safe" situation (RX made "Safe" during TX.)? But if you really
do need to, able to be set so the RX automatically protects itself when
it thinks it is needed, as at present.

But that would preclude allowing receive on the SubRX while transmitting 
- in other words SOTR operation.

We have a KPA500 in our station setup of HU1DL.

After some days of operation (and changing of bands, filters, antennas),
the T/R pin diodes are blown (D8/ D9).

- amplificaton of the RF-input signal works well

- receive level/ noise level in standby is normal

- receive level/ noise level in operate mode in attenuated

Now we are looking for a replacement.

- which type (hope we can buy pin diodes in San Salvador)

- howto change D8/D9 in the KPA500

We also send an email to ELECRAFt support, waiting for response.

When I get my K4 (hopefully May . . .), I currently plan to send in my K3S for repair. I have already talked with support.
The symptoms are:
1) In transmit mode, no power when raising the power above 11 watts. This happens about 90% of the time. So the 100w amp is not totally gone.
2) In receive mode, sound drops considerably when raising the power above 11 watts. This is, of course, coincident with the 100w amp failing.
I haven?t found anything that causes the amp to come and go. Seems random. In can be OK while sending and the suddenly fail.
Also, the transmit calibration fails.

Anyone have this problem? Is there a ?fix? without sending in the rig?

Carl,

Unless you are OK with operating at the 11 watt level and below, I would 
ask for an RSA and send in the K3S as soon as you get it.  Turn around 
times on repairs are typically 2 to 3 weeks depending on the backlog.

The K4 is not likely to ship until late April or early May, and I don't 
know how far down on the order list you may be - I surmise there are a 
LOT of pre-orders.

I know this doesn't have the non-gold pin problem but I would remove and replace 
the KPAIO3A and KPA just to scrub the pins and to make sure everything is seated 
properly.

Thanks Kevin! 

 I tried to answer.  But the signal was buried pretty deep.   I think we are just too close to one another. 

It also seems like the QRM starts up as soon as the net begins, that didn't help.  

 I like trying to pull you out of the noise with APF on the KX3.   Pretty cool feature for CW.

Again tanks for the try!  I did hear part of it!

Good Evening,

    Twenty meters had a little noise and mild QRN.  I had to move the net after a loud CQ started up on net frequency.  Guess they could not hear me.  Forty meters lasted longer than normal.  With the extra daylight I was able to work into Southern California. After I closed with W8OV I heard someone calling him.  I waited and then worked KO6WL at ESP levels.  It took a number of repetitions but I got the call one part at a time.  Even without an active sun signals were fair.  From now until the time change forty meters should work well for us with the longer days.

   On 14050.5 kHz before 2200z:

W0CZ - Ken - ND

NO8V - John - MI


   On 14050.75 kHz after 2200z due to QRM:

K6XK - Roy - IA

K4JPN - Steve - GA


   On 7047.75 kHz at 0000z:

KG7V - Marv - WA

W0CZ - Ken - ND

K6XK - Roy - IA

K0DTJ - Brian - CA

KL7CW - Rick - AK

W8OV - Dave - TX

KO6WL - Howard - CA


I was able to work a few of you before each net which helped.  I did catch an F at the end of the first call up on 40 meters.  I tried calling WM5F, Dwight in Idaho, but the window had closed.

Happy Ground Hog's Day!

David,

the problem is that original KD9SV FES unit is not protecting your radio
against the another RF power sources (SO2R or MM site operation)... FES unit
is disconnecting ext. RX antenna and grounding the input RX port just when
the unit is activated by own radio PTT signal.

In that case the limiters like FEP seems to be much better and it will do
the job perfectly.

Martin, OK1RR has new design of the FEP RF diode limiter for homebrew, just
the article is in Czech language:
https://www.okdxf.eu/index.php/technika/272-ochrana-vstupnich-obvodu-prijimace

Do not worry to ask him for help. I am using his design as an upgrade of his
preview KD9SV saver project and it works perfectly as everything designed by
him.

An interesting thing on EA4TX TRX-FEL design is that it can protect also all
the main TRX ports on the radio (not only ext. RX antenna port) in SO2R and
MM operation.

Subject: [Elecraft] KX3 I/Q output and band width
Message-ID: <363e07da-9c82-5f3c-2b28-f2a0eaeffb62@gmx.net>

Hello,
for a long time I just haven't looked into the details, but now I did
and I'am confused.
When I plug it into a soundcard it appears to show the current station
in the center of the display, to my understanding the center of the
display is the half of the sampling frequency of the sound card.
This ist at least confirmed in the manual pg. 26 (Rev C5).

When I sample the I/Q signal by myself, the same signal appears at the
lower end of my spectrum.
Now it looks like I'm not getting the full bandwidth sampled? With fs of
44.1kHz I can only see 22kHz of bandwidth after FFT.

So, according to many articles I read about FFT, the resulting bandwidth
is always fs/2. So how can we see 44kHz of spectrum on a 44kHz sound
card? I'm confused...

You actually have 22 kHz of in-phase signal and 22 kHz of quadrature signal
on the stereo output. You can combine those to get 44 kHz of bandwidth.

Dear Gang:
I know one could take the PTT signal from the now-discontinued K60XV board, and it is provided on the K2/100 lid, but are there any other option boards that one can use to provide an external PTT signal?
If not, is anyone making the N0SS ptt out boards?? I'm trying to avoid the perfboard route.

Eric,

Send an email to FAR Circuits to see if they have the N0SS Amp Keying 
Circuit for the K2 available.

If you must go the perfboard route, it is not difficult if you follow 
the board layout shown on Tom Hammond's (SK) website 
http://www.mmccs.com/mmarc/n0ss/index_k2.html.  Most of the connections 
can be made using bent over component leads if you follow Tom's board 
layout.

There are few other viable alternatives to sourcing the output from the 
8R signal line.

Don W3FPR

Message-ID: <CAHt1TPW23fEtzWNE--ai12sMzBTRCFGGa5crO7kq+08g=2xu0w@mail.gmail.com>

I had issues with RF feedback on the MH3 during the UKAC SSB 2m contest
last night. It seemed intermittent. Result was terrible noise in Monitor
output (my headphones) and to the other station, so it affects the audio
input. With experiments at the time and this morning:


   - Occurs when RF power is increased above 0 and when Mic Gain is
   increased. I could operate with Mic Gain set low, obviously at reduced
   power out. (Indicative of a feedback loop)
   - Occurs with a dummy load. (Also when I moved the antenna away last
   night). So is the loop internal or is it so sensitive the small leak from a
   dummy load is enough?
   - Does not occur if I feed a stage Mic In through a field mixer (kit I
   have to hand). The field mixer claims an output impedance of 150R and is
   running at mic level to match the MH3 allowing same gain setup in the KX3.
   Mic Bias is turned off in this case.
   - Does not occur on HF into the dummy load.
   - Manifests as buzzing on 2m FM
   - May result in phantom button presses on the KX3 Mic (I didn't think I
   knocked the dial)

As an aside - one station last night was loud enough to activate the "RX"
indicator which I take to be input overload. S meter was well over S9 but
not at the top. I didn't see anyone else at the site, unless they were
hiding the the woodland carpark but I saw no light there or on the summit
behind me. I hit ATT, should have swung the beam to try to null them. But I
guess the ATT and even maybe the input protection is after the 2m module's
input?

My thought is I need to inspect the wiring in the mic. Or could there be
anything else I need to check?

Thanks

Walter,
thanks for the pointer. Will give it a try. Not sure how to combine the
two, lets see.

Even with monitor running into headphones?

I was running the contest with monitor off at first, but I turned monitor
on only in response to my contact telling me my audio was garbled. That
said, I initially wondered if the garble was due to frequency drift not
feedback. Though if it was a monitor problem it would also manifest on HF
and through the vocal mic?

I can try though. I know the headphones leak, closed as they are, as I've
picked up notification beeps when using the field recorder and monitoring
on headphones while recording my voice.

If it is intermittent, then check for the KPA3A not being seated all the 
way down (pull Fan panel, 4 screws and inspect).
Or it could be the relay on the KPAIO3A riser board. To confirm; click 
above and below 12W a bunch of times, if occasionally the RX comes and 
goes, it is that relay.
Components on the KPA3A can make the RX poor, but usually when they 
fail, they are not intermittent.
If you send it in, I will make sure it has the current Revisions of the 
LPA and KPA. There are new ones since your rig was here in Jan 2017.

Message-ID: <CAHXZNSLoaFbiM=wsMa2i3WhhmCp33XqKq6t42WpWGMLWLpz3+g@mail.gmail.com>

I have a barely used Elecraft K1 for sale (S/N-01351), bought the kit back
in 2002, I just needed something to keep me busy, so I bought it and built
it.I love the receiver on this baby, and used it for a lot of weak signal
stuff, I have replaced it with a K3, so I'm looking at selling it.
It's a 4 band unit, not a 2x2 swap, 15,20,30, and 40 meters, has the Noise
Blanker, ATU-4-bands, back light LCD, and the KC6AUP 3d printed folding
stand installed. Basically everything except the internal battery kit.
I have the original assembly manual with my build notes in it, with my
adjustment notes made during the build, as well as the other manuals that
came with the kit.

I'm asking $500, and will take Paypal, we can work out how you want to do
the shipping.

Hi Gary,

Here is the one I use: 
http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=107&products_id=234

It feeds my K3 and I also use the other port to calibrate the oscillator 
for the main MCU on all the K2's I service.

He also sells the Mini version with one output, I have the Mini on the 
K3 and the dual output version on my workbench.

I've done some further tests and proven the problem is with the MH3. So
I'll have to take that apart and look for the problem.
The radio is fine with little earbuds/mic plugged in via splitter cable.
Swap out the mic on the earbuds with the MH3 and leave all the rest the
same and it goes wrong.

 Thanks

Does anyone have any recommendations for a particular 10 MHz GPS disciplined oscillator that would work well as an external reference for a K3S?  I might also use a GPSDO as an external time base for my frequency counter.  Either recommendations or products one should avoid would be most appreciated.  Feel free to reply off list.

The metal shield cover on the 2m module was not flat but slightly raised at
the edge. I have pressed this back on and the problem seems cleared. So I
guess it was contacting or coming close to the circuit board on the control
module, perhaps that giving the feedback loop for RF. Question is - could
any damage have done if it had contacted the vias/pads on the board there?

I used this one from Geppetto Electronics when I last ran temperature
compensation on my KX3:
https://www.tindie.com/products/nsayer/gps-disciplined-ocxo/. One advantage
is that it also produces NMEA output along with PPS, so one could build a
GPS-based NTP server at some point in the future. It also uses a OCXO
instead of a TCXO, so temperature changes should be less of a factor in its
accuracy (though I'm not sure that matters much for normal ham radio use).

I have a Bodnar dual output GPSDO although I don't use it on my K3S.? Be advised 
that the software is very clunky and while you can get two different frequencies 
out, there are limitations on what they can be.

Frankly, I don't know why you would want something like this for the K3(S).? The 
high stability TCXO is fine if you leave the radio powered continuously as I do, 
otherwise, it's quite good after about a 20 minute warmup.? Use your counter to 
measure the TCXO directly and adjust the ref cal parameter manually.

Yes. Headphone to mic distance gets short and feedback can happen from leakage.

I use the Dual Output part from Leo Bodnar so I can set one at 10MHz, 
and the other on a different frequency for use with my VNA.

Additionally, I use Bodnar's NTP Server to serve extremely accurate time 
to everything that I own with an electronically settable clock, 
including my K3s (indirectly).

There are better units available... maybe... but NOT at a cost I am 
willing to pay.

I am VERY happy with my Bodnar stuff.

I bought the BG7TBL one for about $160. I worked perfectly right out of the box.

Dave Van Wallaghen is who I was referred to by Elecraft for a thorny 
problem with my K2. A number of knowledgeable people had looked at the 
problem and given up. Not only did Dave spend a long time with me on 
email exchanges, trying to help me fix the problem on my own, but once 
he got the radio in his hands, he figured out what was wrong and fixed 
it within a fairly short period of time. His bill was eminently 
reasonable. I highly recommend him and his work product to anyone having 
an Elecraft problem.

I highly recommend him.

If a build-from-kit solution would work for you, I can recommend two kits
from
qrp-labs.com <http://qrp-labs.com/>  .  This is the ProgRock
"triple programmable crystal" kit, which can be GPS-disciplined by the
QLG-1 GPS receiver.   I've built these (and other) kits from QRP Labs: high
quality, excellent build instructions, and very economical.  If a sine wave
is desired for your application, you could add an appropriate (probably 30
meter)
LPF kit.

That didn't fix it. Found this lunchtime with a real antenna:

   - Worked OK with case open, testing the idea it was coupling from the 2m
   module itself.
   - Worked on other mic (SoundMagic earbuds and mic)
   - Touching the case with metal made interesting noises on receive.
   - HF (20m) seemed OK, if I take the response "America only please" as
   indicative the other station heard me and my signal was good enough for him
   to tell I was not in America.

I'm not sure how that could happen since the encoder is attached to the front panel with a nut. The nut and the VFO knob would have to both be missing for that to happen.?I just wonder if since I have to take the whole front panel off to replace, should I just order replacements?Does anyone know if the encoders can be replaced if I remove the knob and nut without taking the front panel off?If I get some time this week I'll open up the K3 and take a look.73,Gary K9GS-------- Original message --------From: Victor Rosenthal <k2vco.vic at gmail.com> Date: 1/26/20? 11:56 PM?

I haven't had any failures, but a while ago I ordered some spare 
encoders and pots for my K3, just in case they aren't available in the 
future.

The encoder itself, if you want to re-solder it, is
Bourns Inc.
ENS1D-B28-L00100L

cost is about $58 in DigiKey and $45 in Mouser

Subject: [Elecraft] K2 60 Meter Channels?
Message-ID: <C1EC20DB-8724-48D5-ACD1-8781F8E73B23@gmail.com>

Hi all,
Haven?t used the 60 meter band for over a year in my 2003 K2 and when I went to the band this weekend, it just tunes, no VFO stepping thru the channels anymore?
Looked at the 60M board manual but no luck getting it back to normal.

Can someone point me in the right direction to get the channelization back?
That D19 menu diode option is on.

Thanks for any help!
Ken, W2GIW

Subject: [Elecraft] QRO - KPA500 Failure
Message-ID: <CAF6ucvTjBMHQ_Yu=hR5koaaoBWrA1PDgAisffO5Q5bTruPAYqw@mail.gmail.com>

Was running about 150W on 18 MHz this afternoon. My KPA 500 made a loud
pop. No more output. Any pointers of where to start looking?

*Details:*
KPA500 (use with KAT500 and Icom 7610)
Antenna on this band is a SteppIR
Amp has been running FB
KPA Utility 1.13.7.16
240V supply
A single loud pop was heard.
Mode remained in OPER
No fault light displayed, nor can I find one in the Fault Table

*After the failure:*

*In STBY:*
Radio and antennas work fine. SWR shown to exciter is low, as expected.
Exciter power is displayed on KPA500 power meter.
HV = 78.2
Works correctly on all bands

*In OPER:*
HV = 78.2 key up
On key down (input of 15W) the asterisk briefly displays, then display
changes to 18.1, back to HV display on key up.
Zero output, SWR shown to exciter is very high (over 3 to 1)
No power shown on output meter.
Fails *on all bands* with high SWR to the exciter.
No fault indication.

*Other data:*
Here's the last three entries from the fault table:
00000000  00  PWR ON  --  0007  Power was turned on
00000039  09  REFL HI  80  00F0  Excessive reflected power (high SWR)
00000000  00  PWR ON  --  Power was turned on
.............

Apparently only faults get logged, subsequent power cycles have not changed
the table.

I power cycled the amp, including removing the mains power. - no change.
I reloaded the last configuration - no change.
I removed the cover and looked for any visible damage or bad odors. Nothing
stands out.

Amp is about 4 years old and was a kit model. Before I start to disassemble
if anyone can offer a likely culprit I'm all ears.

Thanks,

Jim/KK1W

Download the K2 manual (unless you have a recent printed copy) and look 
at Channel Hopping on page 103.

Amps making noises like that usually mean you have to take the covers off.

They are easy enough to repair if you are so inclined.  If not, then you
will need to contact Elecraft support and odds are you will have to send it
home for a Spa day.

Since the SWR is still nominal into the amp (as shown on your radio), 
it's not likely the tuned input circuits (which is confirmed from no 
output on all bands).

This points to the high power module.? Running low output power from it, 
is far less efficient than pushing it hard (compare wattages consumed to 
RF watts output delivered at different output levels); which may have 
stressed the finals.? Ideally you run the previous stages at 
low-moderate power for lower IMD, then punch it up with the amp.

The "HIGH SWR" fault you saw is then very likely the final signing QRT 
SK.? You can confirm that with Elecraft wizards.

That module isn't hard to swap out, but it would be best (slightly more 
costly) for the entire amp to visit it's parents, so that other updates 
that may not have been done, can be done. Many of them, really matter.

While also not cheap in shipping and insurance (ask me how I know?) that 
is often the better choice.

Rick, NK7I

I'm not sure who asked the question first, but check your email from
Elecraft support about shipping. I was told Elecraft self-insures, so my
shipping of my KPA1500 amp from Portland, OR to the mothership was
around $20.

They self-insure OUTbound from Elecraft; it falls on the shipper to 
insure, not the recipient.

I had to send in the RF deck (only) of the KPA1500 for factory upgrades 
and I asked for Elecraft to cover shipping.? I waited a few days.

An hour after I got back from shipping it UPS from Idaho (the insurance 
was a killer, total bill ~$180), they approved paying for it.? DOH!

Ask, then be more patient than me.? The worst answer is 'no' and that 
only costs you time to find out.

Elecraft self-insures on outbound shipments (i.e., shipments from Elecraft
to customer).  That means they accept the responsibility of carrier loss or
damage because their history of loss/damage has been low.

The fact that they self-insure doesn't cover shipments to them unless the
company is paying for the shipping, as is the case with a warranty return,
I believe.  Their shipping instructions for repair returns out of warranty
recommend the customer insure the shipment.

I received about a 25% discount from UPS when I shipped my KPA1500 a couple
of months ago due to my membership in a professional society.  You might
check for similar discounts if you have any similar memberships.

"On key down (input of 15W) the asterisk briefly displays, then display changes to 18.1, back to HV display on key up."

Are you saying the "HV" text in the display goes away or that it reads HV 18.1?

Normally the HV display continues to read the PA supply voltage regardless of whether the amp is keyed or not.  It would normally just change from approx 80 V to approx 60 V when keyed.  At face value the results seem to indicate a high voltage supply failure or a fault in the PA that is sucking a very high current.

What is the PA current during the brief period the KPA500 remains keyed?

What are PA voltage and current when keyed if the 60 V line is disconnected from the PA module?

Of course the safe plan would be to send it back but those are some of the test I would try if it were mine.

Jennings RJ1A-26S
Gigavac GH1 with 26V coil

Thank you for your forbearance.   I would suggest answers off the list and

I'm not sure who asked the question first, but check your email from
Elecraft support about shipping. I was told Elecraft self-insures, so my
shipping of my KPA1500 amp from Portland, OR to the mothership was around
$20.

I've never seen much if any advantage in running a linear below its 
rated output.? I know the regulation state never run more power than 
needed for adequate communications or terms like that. ?? The difference 
between 500 watts and 100 watts is 6.9 dB or about 1 S unit.

In fact, most all of the time, running at less than rated output is less 
efficient.?? It saves nothing.?? Same for tube amps where I hear hams 
say they are running at reduced power to "save the tubes".?? Nope, not 
the case.

(RF output / DC input) * 100 = % efficiency???????? DC input watts? = DC 
volts x DC amps

Do the math and you'll see what I mean.

A quick run of the numbers with my KPA500 into a dummy load. Output 
measured with a Bird 43.? DC values taken from the KPA500 display

450 W out, 819 W input, 64 volts @ 12.8 amps for 55% efficiency Drive 
pwr = 16.5W? 14.3 dB gain? ?? 819 - 450 = 369 watts = heating factor = 0.88

210 W out, 576 W input, 67 volts @ 8.6 amps for 37% efficiency Drive pwr 
= 7.0 W? 14.7 dB gain ??? 576 - 210 = 366 watts = heating factor = 1.74

100 W out, 393 W input, 69 volts @ 5.7 amps for 25% efficiency???? Drive 
pwr = 3.2 W? 14.9 dB gain ? 393 - 100 = 293 watts = heating factor = 2.93

As a follow up to my previous message I measured PA voltage and current for OPER mode not keyed and OPER mode keyed with no RF drive input.

PAI  not keyed  .0,  keyed  .2
PAV   not keyed  80.9, keyed  77.8

Hi reflected power fault can't happen with no drive so won't influence the results.

When I blew the final on my KPA500 Elecraft diagnosed the problem.  I had to
make a few meter readings and they figured out the problem.  They gave me
the option of removing the transformer for shipping (most of the amp
weight). They gave me instructions to remove and reassemble when it
returned.  Saved a lot on shipping.

Good luck

Basically, based on Bob's measurements, the power dissipated is fairly 
independent of drive level. So, running at reduced power really isn't 
stressing anything any more that full output. (Unlike an "ideal" class B 
amplifier.)

"Basically, based on Bob's measurements, the power dissipated is fairly independent of drive level. So, running at reduced power really isn't stressing anything any more that full output."

I have done quite extensive testing of my KPA500 and provided links to my results.  My KPA500 PA dissipation is strongly dependent on the PA load but, for any given load, the peak dissipation is at out half power output.

I thought I'd mention a tip I've done to filter out fine dust from being 
pulled into the KPA1500 power supply.? My unit runs 24/7 and I was 
surprised how rapidly the fan grid on top of the power supply gathered a 
circular collection of dust, even though the floor is tiled.

I picked up a package of washable foam filter material at the home 
store.? It is normally used as a replacement air conditioner filter.??? 
Here are a few shots.?? Looks like it's time to wash it again...

Probably because the folder you?re choosing for firmware files cannot be written to without admin privileges. Most folders under Program Files require admin permission for write. It?s intended for programs, not user data.

Click the default button on the KX3 Utility Firmware tab, and the utility should then be able to write into that folder.

Or choose a different folder under your user folder...

Hi,

I got bored today, and graphed the input power vs. the output power of 
my KPA500 across 160 through 10 meters.  I put the results on my web 
site at:

I run my KPA500 output just below the level I feel I can get away with...without lighting up the neighborhood. About 350 watts :)

Putting my brand new KPA-500 through its paces and I?m noticing a significant difference between the peak power displayed on the amp, and the peak power displayed on a Telepost LP-700 station monitor.  With the amp peaking at 500 watts, the LP-700 will often show peaks in the 600+ watt range. The trapezoidal display on the LP-700 does not show any non-linearity during such operations.

Is this then simply a difference in how the power is metered?

It's heat that stresses the transistors, not efficiency.
The numbers show more dissipation with increasing power level.

Just FYI,

as Pablo, EA4TX confirmed the relay used for T/R switching to bypassing FEL
while radio is transmitting has operating time in between 5-7ms and
releasing time even 7-10ms if parallel diode is used.

So it is not usable on CW ...if your K3 will start transmitting first
element previously then FEL limiter is bypassed the RF power from K3 can
damage the limiter. 
If your K3 will be back in RX mode again faster then FEL released to
protection path then your K3 is not protected during that period...

Different metering systems will have different attack and release times.  Most won?t be able to  follow the voice envelope accurately.   

It is best to use steady state carrier when measuring power.   500 watts of carrier is the same as 500 watts PEP. 

If your transceiver drives the amp to 500 watts output with 20 watts, then the correct drive power for SSB is also 20 watts.  The K3S feature of PWR PER BAND is excellent in this regard.

"It's heat that stresses the transistors, not efficiency. The numbers show more dissipation with increasing power level."

Which number show that?  My test data for the KPA500 are very clear.  Peak PA dissipation for any given load is at about half power output.

There may be reasons for running at less than the amplifier max such  
as the US 200 watt 30m band limitation.  I have no RF engineering  
knowledge but after looking at your data I see less heat with lower  
output wattage which seems to me like it would be less stress on finals.

With a switchmode power supply, it would seem to be simple
to provide one or more lower voltage outputs to keep efficiency
up at lower powers (maintain same load Z).

John,

You are correct.  I am seeing a lot of confusion and erroneous 
conclusions based on the terms 'efficiency', 'dissipation' coupled with 
'power output'.
As an example, consider that a PA running at 50% efficient at 500 watts 
will dissipate 500 watts of heat and 500 watts of power out.  Input DC 
power will be 1000 watts.
Now back the power down to 250 watts - yes, the efficiency will be less, 
say 33%.  That is 250 watts of power output, but 67% of the total power 
into the amp would be lost as heat - 417 watts of heat.  Input power is 
less too at 667 watts.

That drop in efficiency at lower than max design power is true for any 
amp designed for their maximum rated power output (as most are).

The only ones who should be concerned are those who are monitoring their 
draw from the AC line and their resulting utility bill.

73,
Don W3FPR

I had one off-line request for my test data so I'll share a link:

https://www.dropbox.com/s/uf258k1nw8o7xw3/Evaluation%20KPA500%20PA%20Dissipation%20rev%20ad4.pdf?dl=0

I have previously shared other links to reports that are based on the same raw data set.

Please note that the plots in this report contain no data for efficiency but efficiency can be derived from the plotted data.

Efficiency is the ratio of RF output to PA DC input power.   You can derive DC input power from the plotted data by adding RF output to PA dissipation.  In the raw data set I have PA voltage, PA current, and RF output.  I calculate PA DC input power then subtract RF output to give PA dissipation.

This is a draft report and may contain errors.  Comments on test method or results are welcome.  My QRZ address is valid.

output mod).  I'll be ordering the N0SS board when I get back North next
month.

Is there an "original" document that went along with the N0SS circuit, which
might
suggest where/how to mount the board, and where to pick up the K2's 8R
signal?

Thanks!

Bruce,

As original as it gets is Tom's own documentation.  BTW, the board 
header goes in K2 RF Board J13 which has power for the circuit as well 
as the 8R signal.  Solder the header into J13 and mount the output javk 
on the rear panel - populate the board and plug it in.

Go to Tom's website preserved at http://www.mmccs.com/mmarc/n0ss/. 
Scroll down to Elecraft K2 - Related Files.  On that page you will find
the K2 (BASIC) External T-R Relay Driver.  Click on that link to open 
the .pdf document.  The parts list Mouser numbers may have changed, but 
otherwise the parts list is complete.

Subject: Testing IMD3 (dB) K3S (#10490)

 

Hi 

 

Can anyone roughly confirm IMD3 K3S ? 

 

10W/100W module recently exchanged under Elecraft swap program Rev A (2019).

Testing: Using K3S internal 2 Tone and -60dB power attenuator (50Ohms) , HP
8591E Spectrum Analyzer (Span 10kHz)

 

72W (Tune, LP100A)out into 50Ohm: 

IMD3 (#10490) -->about on 160m 34 dB, 80m 32dB, 40m 34 dB, 20m  26dB, 17m 30
dB, 10m 30dB, 6m 26dB

Yes, all was aligned (TX Gain test) and showing 100 to 90W full power on all
bands.

The driving signal to 10W PA (one tone) looked better than 50dBc.

 

I think these IMD3 values are not very impressive. A power amp. would
typically further degrade the overall results.

So K3S is rather good for CW but not really good as SSB preference? (I have
now also a FTDX101MP)

 

Comparing with K3 (#7848) upgraded myself to "S", but still maintaining the
old 10/100W modules.

80m and 20m were better by about 6dB!?

 

The two tones (IMD3 Test Tones) however were in both cases never absolutely
identical in amplitude (ca. +/-1dB) on the analyzer.

 

Any comments?

 

Tnx, Cu, vy 73 de Andy

In practice, no, because the K3 and K3S IMD is significantly lower at 
the power levels needed to drive an amp. My 87As need 45-55W, my KPA1500 
30-50W, and KPA500 25-30W, in all cased depending on the band. IMD is 
also minimized by running the radio near the top of its design range 
13.8V nominal, 15V max).

When they were introduced, the K3 and K3S both pushed the state of the 
art for CW bandwidth with low phase noise and a carefully shaped keying 
waveform (that others took years to copy). My measurements of the TX 
bandwidth of my K3 and several other rigs I was able to borrow are here.

http://k9yc.com/P3_Spectrum_Measurements.pdf

It's also important to realize that IMD increases CW bandwidth too, 
because CW is actually 100% square wave amplitude modulation of the 
carrier. Compare slide #9 with #14 - 16, for example. Those little humps 
that look like sidebands are IMD, and are heard as clicks. Compare slide 
#17 (100W SSB) with those that follow. Pink noise is used as a test 
signal because it's spectrum and dynamics far more closely resemble 
speech that white noise.

Andy,

I'm sorry that your testing showed low TX IMD. Typically all HF bands are in the low 30s (i.e., -30 dBc or better, using the ARRL method, with Vsupply = 14 V). This is similar to that of other transceivers using the same MOSFET PA design. 6 meters is tested at a lower power level per the current specifications (I believe it's 1 dB below 100 W).

If yours is worse than the low 30s on one HF band, 20 m in your case, there are a few possibilities. It could be that the 20 meter LPF is not optimized, or that the voltage regulator supplying 5 V to the bias circuitry is off by some amount relative to the normal value. 

If you sent the radio in at the time of the module swap, our techs should have caught this in final test. If you did the swap yourself, then one of the above issues may apply.

Either way, I've asked customer support to contact you, and we'll be happy to cover the cost of any replacement parts on the radio or the modules.

73,
Wayne

General discussions indicate a higher supply voltage, approaching 14.0 
to 14.3 at the radio during transmit, does produce lower IMD products.?? 
On the opposite side, lower voltage has been shown to produce higher IMD 
products.

The KPA3A is a Rev E in my radio.??? The supply voltage as shown on the 
radio during 100 watts transmit is 13.9 with 14.3 at the supply. ? I've 
not measured the IMD.

Mitch
Did you receive any answers to your question in this post.  

I currently control my KPA500 KAT500 combo using a Win  7 machine and the
server in the Elecraft remote s/w.  I connect to both from my control
location using shack PC and the client side of the software.  I want to
eliminate the PC at the remote end and use a 2 port ethernet to serial
server from Startech that i have purchased.

I am trying to figure out how to set this configuration up.  I assume I use
the server host option in the Elecraft software but not sure.

Did you receive any answers to your questions?

FYI:

I asked one of our U.S. military KX2 customers (a special forces commander) to describe how they use the rig. Here's the verbatim quote:

* * *

"We use the KX2 to enable us to communicate in emergency situations where military-issue gear is unsuitable, impractical, or has failed.  Its form-factor is ideally suited for increasing the redundancy of our communications without any noticeable increase in weight or bulk.  In addition, and perhaps most importantly, it is used to interface with civilian radio operators when we are assisting with civil emergencies, such as those that are caused by hurricanes or earthquakes.  Unfortunately, we have been called to assist with both of these scenarios lately, and the ability to interface via HF using a tough, portable radio has been instrumental in passing critical information in environments where cell phone and internet networks were non-existent."

* * *

I'm hoping he'll release additional details in the future, but he's asked that we not discuss his actual deployments, names, unit, etc. He did say that many units have been outfitted with KX2s for the reasons above.

If you have a specific question or reason to contact him, I'll be happy to forward the email. He seems to come up for air every week or two, between ops.

Pedro,

If it were a K2, I could tell you that the diodes in the wattmeter have 
been damaged and need to be replaced.  Those symptoms are almost the same.

The K3 controls power in a similar manner, and I would suggest you start 
with the wattmeter - I believe it is on the KAT3 board in the K3.

Wayne,

This information is extremely interesting and more than a little unexpected.  I am fascinated by the capability of the KX2 (mine is 2.5 years old), but its internals have very little isolation and protection from adverse ambient conditions...an essemtial requirement for most gear in military service.

1.  Is the KX2 supplied by Elecraft identical to those supplied to amateurs?  It would be interesting to know if and what its military users have fashioned some protection from the elements.  At the least, the aftermarket Kx22 heat sink, SideKX left side panel, and SideKX cover would seem appropriate.

2.  Is the KX2 being supplied by external DC power?  I'd predict short life for the speaker connections with frequent removal of the bottom cover for KXBT2 replacement.

3.  The stock KX2 (unfortunately) provides no transmit coverage outside the ham bands except 5.06 to 5.45 MHz for 60m.  Is a special firmware load being used to permit general coverage transmit?

4.  Federal agencies (including CAP, but not MARS) normally use radio equipment compliant with standards established by the National Telecommunications and Information Administration (NTIA) which manages the use of all federal spectrum.  Agencies self-evaluate equipment specs using information supplied by the equipment manufacturer.  The CAP currently shows at

  https://www.gocivilairpatrol.com/programs/emergency-services/radio/communications/radios-radio-network

a broad spectrum of ham and commercial gear in which only the FT-817 with TXCO-9 meets NTIA specs.  They evaluated the K2, K3S, and KX3.  I suspect the military users of the KX2 have not formally evaluated its NTIA compliance.

US military agencies have sometimes adopted commercial radio gear with no changes.  In 1965 the Collins KWM-2A MF/HF SSB/CW transceiver was adopted as the RT-718/FRC-93 ...and it had very little protection from adverse environmental conditions.

I have some comments. 

My TX IMD is even worse and I was not very happy with the advice I got from Elecraft.  I was advised to use the radio in test mode and use an external amplifier.

Periodically I have a complain about it. My 10W PA is also poor even after the FW upgrade that allows additional attenuation to the drive. There are a few of us who discuss this off reflector and it is by no means uncommon.

On a more positive note I must say that the transverter port output is exceptionally good. Its really impressive.

As for the PA IMD, good luck, you will need it.

Regards

Subject: Testing IMD3 (dB) K3S (#10490)

 

Hi 

 

Can anyone roughly confirm IMD3 K3S ? 

 

10W/100W module recently exchanged under Elecraft swap program Rev A (2019).

Testing: Using K3S internal 2 Tone and -60dB power attenuator (50Ohms) , HP 8591E Spectrum Analyzer (Span 10kHz)

 

72W (Tune, LP100A)out into 50Ohm: 

IMD3 (#10490) -->about on 160m 34 dB, 80m 32dB, 40m 34 dB, 20m  26dB, 17m 30 dB, 10m 30dB, 6m 26dB

Yes, all was aligned (TX Gain test) and showing 100 to 90W full power on all bands.

The driving signal to 10W PA (one tone) looked better than 50dBc.

 

I think these IMD3 values are not very impressive. A power amp. would typically further degrade the overall results.

So K3S is rather good for CW but not really good as SSB preference? (I have now also a FTDX101MP)

 

Comparing with K3 (#7848) upgraded myself to "S", but still maintaining the old 10/100W modules.

80m and 20m were better by about 6dB!?

 

The two tones (IMD3 Test Tones) however were in both cases never absolutely identical in amplitude (ca. +/-1dB) on the analyzer.

 

Any comments?

 

Tnx, Cu, vy 73 de Andy

I know for the KX3 that it can be ?unlocked? to be used outside the ham
bands.  I would assume the KX2 has the same facility. For my KX3 I needed
to show my operating authority as an Army MARS operator.

Yes. They may be using aftermarket accessories -- not sure.

I believe they use it with both internal and external battery.

Just the MARS enable.

I believe the KX2 was approved for COTS (common-off-the-shelf) military purchase.

The point we were trying to make is that the KX2 fills a functional need that is not presently filled by other gear, with or without compliance to specific standards. They needed a 1-pound radio that covered all modes and all bands. Someone showed them a KX2 and demonstrated that it did the job.

If the KX2 were EMI-hardened and ruggedized and waterproofed to the degree that some manpack radios are, it would simply be another large, heavy, overpriced piece of military gear. As it stands, it does the job they need it to, just has it does for thousands of hams using it for SOTA, hiking, backpacking, etc. To roughly paraphrase, it was a tenth the weight, a tenth the size, and a tenth the price. 

With all that going for it, they could afford to lose a few. But the rigs have proven  very reliable. (Wish we could post the entire, colorful history of what their rigs have been through. It was scary! Amazing that the soldiers survived, much less the radios.)

Hi from HB9CVQ Andy

My K3S / K3 voltage under load (72W) was 13.1V DC.

As a former DoD contractor:? Both the FAR and DFARS have specific 
sections defining the requirements for the DoD to purchase Commercial 
Off-The-Shelf [COTS] hardware and software products.? Much of those 
sections is devoted to who owns the patents/copyrights and distribution 
rights.? It's nearly always up to the Program staff and Contracting 
Officer regarding technical specifications, however the competition 
rules still apply if there is more than one available product that meets 
the specifications. A program can purchase "samples" for evaluation from 
any mfr and I'd guess that the KX2 has little or no competition.

Products that are for general military needs [e.g. ruggedized vehicles, 
flight and space qualified devices, etc.] are almost always purchased 
via contract, often as Task Orders on IDIQ [indefinite delivery 
indefinite quantity], multi-vendor contracts.

Personally, I think it's cool!? In the 60's in SE Asia, our "portable" 
A/G radios were 35 lb back packs [AN/PRC-10's] and the dry cell 
batteries would last a few hours ... unless you transmitted.? Can't 
imagine how a KX2 would have changed things on mission for us. [:=)

Normally, I would think maybe a transient power issue, due to ALC overshoot
or poor 110/220 volt mains regulation. I don't think the latter would be the
case with a KPA500.

The LP-700 is very fast, and will respond to very short transients of power.
You can slow the meter response down using the Peak Resp(onse) setting in
SETUP if you like. I assume that you have the K3 power set to just enough to
drive the amp to 500 watts. I like to use a small amount of CMP (6-10 dB) to
set a stable upper limit, and then set drive to just at the threshold of
ALC.

Good Evening,

 ?? We had a burst of solar wind this week.? That should help the 
ionosphere.? The auroral oval was strong this morning, it is less so 
now.? I expect some QSB for tomorrow due to the wind but it shouldn't be 
deep.

 ?? There are a few flowers at lower elevations.? I uncovered some 
daffodil shoots while moving wood.? That one tree has heated the house 
all winter and should last another month.? I have some packages held up 
in shipping somewhere between the Mississippi and the Rockies.? Stuck 
for three days.? It must be quite a storm.


Please join us tomorrow on:

14050 kHz at 2200z Sunday? (2 PM PST Sunday)
 ?7047 kHz at 0000z Monday? (4 PM PST Sunday)

73,

 ?? Kevin. KD5ONS

You know not even the coastal villages was safe from
them big clams. You know them big clams had an inland
range of about 15 miles. Think of that. I mean our
early pioneers and the settlers built little houses
all up and down the coast you know. A little inland
and stuff like that And they didn't have houses like
we got now, with bathrooms and stuff. They built little
privies out back. And late at night, maybe a kid would
have to go, and he'd go stomping out there in the
moonlight. And all they'd hear for miles around...
/[loud clap/belch]/....one less kid for America. One more

13.1 V is too low for reasonable IMD with *any* 12V "100W" PA.
Get the power supply up to 14.0-14.5V. If you can't get at
least 14.0 V at full output, do not try to run more than 60W.

Note: this is into a *non reactive* 50 Ohm load.  If the load
differs from 50 +/- j0 Ohms, IMD is likely to be worse due to
the mismatched load.

Joe makes a very good point. Even with 14.5 V and a perfect 50 Ohm load, 
12 V PA's have marginal IMD at 100 W. If there is a moderate mismatch, 
like 1.2:1, it can be much worse. Given that? ATU's don't consistently 
get the SWR below that, IMD is often likely to be pretty bad. (It would 
be very interesting to see some test results with 1.2:1 at various phase 
angles.)

Fortunately, a lot of amplifiers, including all the solid state ones, 
require much less drive power. Unfortunately, some of the solid state 
amplifiers are also likely to generate more IMD if they aren't perfectly 
matched. (And they're not that great when they are matched.) Reducing 
power a bit should help. Running an amplifier capable of 2.5 kW at 1.5 
kW would probably keep the IMD pretty low, even with a moderate 
mismatch. It would also be very expensive.

Thank you very much Don;

I have been testing and when do a tune the power is always 100 w although I have it set to 15 w in the TUN PWR menu., always 100 w.

In normal operation, cw or ssb, I can choose the power between 0 and 100 w without problem.

I will start checking the wattmeter.

Thank you very much for your help.

Pedro,

If it were a K2, I could tell you that the diodes in the wattmeter have 
been damaged and need to be replaced.  Those symptoms are almost the same.

The K3 controls power in a similar manner, and I would suggest you start 
with the wattmeter - I believe it is on the KAT3 board in the K3.

I periodically (year or two) see power overshoots on my K3/KPA500, and
running TX CAL a couple of times fixes it.

Pedro,

If it is not present with a long keydown in CW, and only in TUNE, the 
wattmeter is NOT the problem.
Check your K3 menu for the setting of TUN PWR.
What does ATU TUNE do?

I saw the subject and thought "who would sell a K2?" They would have to 
pry it out of my... etc.

Not a whole lot new, but interesting, especially an actual lab version of the K4/0.

I wonder if the coronavirus mess is going to have any impact on supply chain and delivery schedules?

Yes, it can work, but you will be better served by using the super 
flexible Heil cable available from Heil Sound and perhaps other sources.

Greetings

I am looking for a battery pack for for my KX3 station with a KXPA100 
amp and accessories. I also have a BiPAP (CPAP) machine. It has a 
12V/6.67 amp power supply. When boon docking, the battery pack has to 
support needs to support a day of haming and the BiPAP for about 8 hrs 
each night.

IIRC: I had found a couple of companies that manufactured power pacs in 
different chemistries, voltages and sizes. They also had good 
descriptions of the advantages and disadvantages of the various Li 
chemistries. I have lost track of them through various computers.

I looking for a reputable company that can build me a battery pac that 
has good safety features and of suitable size. I am not necessarily 
looking for the cheapest battery pac--safety, reliability? and 
appropriate storage capacity are primary concern. Cost is factor as 
well, but I am wary of bargain basement specials.

Thank you, Al ve7ear

Yes, very true.  Only a few have actually contributed test data.  All the rest is assumption and speculation.

I'd like to sell my trusty KX1, sn01151 in order to upgrade to a 2 or 3.

This unit has four bands, 80, 40,30, and 20.  Autotuner, and paddles.  Works
great and used on SOTA activations.  

I don't know how much these older units are going for, so make me an offer.

I just can't resist writing this.? If you're tired of praise for 
Elecraft, please delete.

I bought myself a KPA-1500 for Christmas, 2018.? It worked just fine, 
though with a couple of quirks.? In particular, I had two quite 
dissimilar antennas for 40M, and while working Assisted S&P with 
occasional large QSYs the amp would sometimes throw a high reflected 
power fault.

This fall, I wrote to Elecraft Support about this, and found myself in 
very detailed correspondence with Dick Dievendorff and Bob Wolpert. 
Dick's the firmware author, and he produced at least two beta versions. 
The latest one, which is now the production version, completely solved 
the problem - now when I move 60 KHz and change antennas, the amp 
gracefully retunes itself and settles in for the fun part.

It's like having a 1500-watt transceiver

LiFePO4, the best balance of power per unit volume/weight and safety.
They probably have one to meet your requirements off the shelf, but they 
are capable of producing pretty much any custom battery you require.

Sizing would depend strongly on number of nights and transmitting
time, but the bioenno lfp, a cigarette lighter adapter for your model
bipap, a powerpole to 12v socket adapter,would cover things pretty
well.

If you want to fly with it, consider getting two separate 96Wh
batteries to avoid FAA hassles.

I have a 12V 20 Ah (240 Wh) LiFePO4 and it will run my heated CPAP machine
(likely a different model) for two nights in a tent (about 50 Degrees F).
The FAA will allow two spare batteries up to 160 Wh each most of the time.

I think, unless you can charge the battery before using it for the radio,
you should have a different battery for the CPAP and the radio, maybe two
or three and rotate them, rather than trying to use it for both, running it
down with the radio and not having enough for the night to run the CPAP
machine.

I'd also suggest you get a 12V Watt Hour meter and see how much the two
devices actually use with your specific conditions. I bought ones like
these and added my own Powerpole connectors:

https://www.amazon.com/dp/B01LVTST80

You usage will not be the same as someone else's and the CPAP usage
depended on the ambient temperature. I did not use an amp with my KX3, so
even a 3.8 Ah battery lasted hours.

Andy,
    Yes, you are right and this applies to both KPA 500 and KPA 1500.    The
conditions for maximum efficiency are not necessarily those for minimum
dissipation or reduced stress.    I would like to know if running 2/3, 1/2
or even 1/4 maximum power output increases reliability and MTBF.    It would
be a considerable surprise to me if this were not the case and it would be
good to know the numbers.    Improvement in MTBF can be several fold for
some devices for a reduction in voltage, current or power of as little as
10%.    Good design practice normally means that this is part of the
engineering design process.   The proof of derating is looked for in design
reviews.   Too many hams run their amplifiers flat out for very little
benefit.   Signal cleanliness is still another issue; higher voltage but
lower power seems to help here.

     Using FT8 or WSPR on dead band (160M in daytime or 12M), I sometimes
run 20 Watts plus.   This can be stressful on the K3 especially for WSPR.
I crank the K3 down to a watt or so and drive the KPA 1500.    Yes, my total
energy consumption is no doubt up but stress on either K3 or KPA is minimal.
This however is not my concern, I would like to know if running the KPA at
lower power increases reliability.   In EI we can run 1500 Watts for
contests  but outside of contests can only run 400W max.

                              73 Doug EI2CN

"I am seeing a lot of confusion and erroneous conclusions based on the terms
'efficiency', 'dissipation' coupled with 'power output'."

Yes, very true.  Only a few have actually contributed test data.  All the
rest is assumption and speculation.

Doug,

"I would like to know if running 2/3, 1/2 or even 1/4 maximum power output increases reliability and MTBF."

I have no experience of amplifier design but I would expect reliability of the finals to depend on temperature.   Finals temperature will depend on the power dissipated in the finals (PA dissipation) and the effectiveness of the cooling design.

To understands finals dissipation one would need to produce one's own test data or rely on the work of others.   My test data for the KPA500 shows PA dissipation peaks at about half power output.  So far no one has disputed the validity of my test data.

It is my understanding that running an amplifier at reduced power only reduces PA dissipation if the finals voltage is adjusted give a good load match for that reduced power condition.  The KPA500 has no provision for adjusting PA voltage for the reduced power case.   For reduced power the PA voltage is actually higher than for full power because the high voltage supply is not regulated.

As I said, I have no experience in amplifier design and would appreciate comments from those who do.

How you use your CPAP will have the biggest impact on your decision.  Heat
and moisture adds a significant impact on the size of the battery.  I would
also suggest two separate packs.  This will guarantee you always have what
you need for your CPAP and may even have a back up.  There are some nice
LiFe systems out there that have a solar controller built in which will
allow you to run a small solar panel to charge it while using the radio.

Hello Andy,

     I do not have the numbers and also would like them.     I understand
that efficiency decreases as one derates from the maximum of 1500W output.
It surprises me that the power dissipated would peak at half power output or
750 Watts.   This may be so.    If so then almost certainly the Mean Time
Between Failures or MTBF is worsened.     I am not in a position to
determine any of this but maybe some guidance from Elecraft itself would be
helpful for both KPA 500 and 1500.

One point to consider is the output network that is used to match the output device impedance to 50 ohms.  It is a fixed value or ratio.   Thus if designed for rated power then at 1/2 or 1/4 power the value would not seem to provide a proper match for effective transfer of energy.  This can attribute to overall efficiency.

Several others have posted test data for the KPA500 here recently. As I 
recall, it shows that dissipated power is fairly constant from about 50 
percent to full output, at about 500 W, dropping a bit at lower power.

If it were an ideal class B amplifier, which no solid state RF amplifier 
even approaches, the efficiency at full output would be 78.5 percent.? 
It would then dissipate only 141 W at full output, and maximum 
dissipation would be at some lower output power level. This is probably 
what folks are thinking of when they assume maximum dissipation occurs 
at less than full output. REAL RF amplifiers don't behave that way, as 
the test results show.

"I understand that efficiency decreases as one derates from the maximum of 1500W output.It surprises me that the power dissipated would peak at half power output or 750 Watts."

I have no test data for the KPA1500 and will not speculate on the shape of the PA dissipation curves.  All I have is data for one KPA500.  For that one KPA500, and under the conditions tested,  it's clear that PA dissipation is greater at half power than at full power.

It would be easy to get a pair of data points for the KPA1500.

Connect the amplifier to a known good 50 ohm load.
Drive the amplifier to steady state 1500 W output
Record PA current and voltage
Drive the amplifier to steady state 750 W output
Record the PA current and voltage

Repeat on multiple bands if desired and report the results here.

Subject: [Elecraft] K3: Unexpected AGC action
Message-ID: <33bd2b5e-41df-e3c6-ae69-b0b2193a0e69@nk7z.net>

Hi,

I have a K3, and am seeing what looks to be some sort of unknown, and 
unexpected AGC action when I have AGC off, on both the K3, and within 
Windows.

I am trying to triage this to the radio, the computer, or WSJT-X.

Here are the test conditions:

WSJT-X used as the software for testing.  K3 is feeding audio directly 
to the computer via a USB cable, Windows 10.  I believe I have AGC off 
in Windows...

Here is what makes me question the AGC:

1.  K3 bandwidth set to 4KHz.
2.  WSJT-X showing 0-4000 Hz in waterfall.
3.  If I reduce bandwidth using the control on the K3 I see:
        a.  A reduction in the level shown by WSJTX input meter.
        b.  An INCREASE in noise on the waterfall.

This is totally unexpected to me...  I would expect to see the waterfall 
stay the same brightness, and the waterfall width reduce, while the 
input meter drops.  Why the brightness change?  Is this happening within 
WSJT-X?

"This is probably what folks are thinking of when they assume maximum dissipation occurs at less than full output."

A possible source of error in my data is that the dummy load is cool at the start of the power ramp and hot by the time peak power is reached.  I recorded LP-100A data during each test run and can see some change in the load characteristics.  I did not attempt to compensate for this when plotting the data.  I simply reported values of R and X that were about average for each test run.

One way to find out if the change in load is significant would be to start the power ramp at maximum power rather than minimum power.

Some time after I ran those tests I expanded the capability of my Arduino station controller to add a page that displays  PA voltage, PA current, PA DC input, PA dissipation, RF Output, and efficiency.   A snapshot of the displayed data can be sent to the controller's logger output.

I just ran a test which had a brief transmission close to full power and another brief transmission at half power.  This test was performed at 14.01 MHz using a dummy load.  Here are the data:

26:36:36.672  KPA Mon frozen
PA voltage=60.6
PA current=14.1
PA input=854
RF out=495
PA diss=359
PA effic=57

26:37:32.437  KPA Mon frozen
PA voltage=64.6
PA current=10.0
PA input=646
RF out=250
PA diss=396
PA effic=38

Dummy load heating would not have been significant factor in this test but the results still show higher PA dissipation at 250 W out than at 495 W out.

It's really simple to produce a similar data set and there are lots of KPA500 owners here.   If you think my data are invalid please share your test data.  I don't mind being wrong as long as I learn something new.

I would like to see the KPA-1500 have a "Medium Power" setting with optimized bias for that power level so the amp could be operated at 750-watts output and good efficiency.? While the KPA-1500 can operate FT and RTTY contests at 1,500 watts, I believe the amp operated at 750-watts with an optimized bias setting for that power level?would generate less heat and less fan noise, both of which would be very desirable when full power isn't required.? ?

I'd sure appreciate Elecraft adding a half-power setting with optimized bias at that power level.? While the KPA-1500 can be run at half-power now, the efficiency isn't very good.

Unless one is concerned about power consumption, the efficiency factor should be really of no concern.   Total heat output will always be greater at maximum output and less at lower power.  Nice for warming the shack on a Winter day.

Yes, I was wondering why this was so interesting.

Thank you Andy,
Bob, if maximum power dissipation occurs at 50% max output power then the greatest amount of heat should be generated for the shack at half max output power.  Power dissipation is in the form of heat not RF.   The subject is interesting for a number of reasons perhaps most importantly to me is that of reliability.  I believe the chance of failure is reduced as one lowers dissipation while staying within all other component ratings.

Unless one is concerned about power consumption, the efficiency factor should be really of no concern.   Total heat output will always be greater at maximum output and less at lower power.  Nice for warming the shack on a Winter day.

Oh but contraire.?? I agree that lower dissipation typically reduces 
MTBF.?? Therefore, never plug in your KPA500, leave it in the box and it 
should last a very long time.

Sorry folks, I just couldn't resist.


I did not do extensive measurements, but the ones I did show the following:

450 watts out, 819 watts in, for a delta of 369 watts, I presume for 
heat or 55% efficiency

210 watts out, 576 watts in, for a delta of 366 watts, I presume for 
heat or 37% efficiency? {I do work 30M that has a power limit of 200 watts}

Note the difference in heat dissipation between 450 watts out and 210 
watts out is only 33 watts but is 240 watts difference in RF output.? 
Based on these numbers, there is not a lot of difference in heat to be 
dissipated in the upper half of the power rating.

100 watts out, 393 watts in, for a delta of 293 watts, I presume for 
heat or 25% efficiency.

UPDATE:

Jack/W6FB contacted me directly shortly after posting. I sent him my fault
log to analyze and a detailed description of my equipment setup. Best guess
is a cable or antenna failure causing high SWR sometime in the recent past
that stressed the finals. They gave up the ghost when I was running 17m FT8.
I'm leaning toward a bad patch cable I found between the KPA500 and KAT500 a
few months previous to the failure. A cheap cable that became very costly!

His guess was right on, when I was pulling the power transformer out of the
amp to make it easier to ship I found the ceramic part of a VRF2933 MOSFET
rattling around in the cabinet. The problem is now obvious :(

The amp left today to Elecraft for repair. I'll let the group know the
results once it gets there.

Thanks everyone for your constructive comments and to Jack for reaching out
and helping me find the problem.

Bionenne Power is a great source for batteries to do radio. You'll need 
to find out the power requirements for you CPAP machine (voltage, 
current, and duty cycle) to choose a battery pack for it.

I hate texting.  So inefficient.  Take out the phone, put the reading glasses
on, yada yada.
Wonder if anyone has found a decent SMS to Morse app for Android?  I've
looked in the google ply store and see one called SMS-Morse, but I haven't
tried it yet.  Didn't really see any others that might fit the bill. 
Anyone?

I am looking for thoughts and suggestions to diagnosis what I am seeing.
When the amp is changed from STBY to OPER the receive signal drops by
multiple db and the general background seems to increase significantly. The
tuner seems to work the same with or without the amp. When I transmit it
appears I am getting full power output. I am driving the KPA-500 with a K3.

 

Thanks in advance

If there is a relay in the rx signal path, check the contacts. I had that happen with my Alpha recently. Of all the possibilities that was the easiest thing to fix. Thankfully that was the problem :-).

Bill,

No relays in the T/R switching path for the KPA500 - all solid state 
switching.

It could be D36 & 37 on the RF board. Earlier ones (1st few thousand) 
had weak components. But any of them can fail and usually there is 
runaway power out.
If that is not it, look for burned components under the KANT3 board 
around T4 or on the underside near D36 & 37 look for burnt traces.
If it is older than about #5500, it could be front panel tin pin 
oxidation, replaced them with gold.

If you notice a drop in signal strength when simply switching the amplifier
from "Standby" to "Operate", it means that the T/R diodes are biased for
transmit (not receive).  Check R7 the 51 ohm SMD resistor on the daughter
board as the most likely failure.  It has happened to me and several others
on the reflector.

I  checked the operating specs on two of my QRO amps.  Not a KPA500.

2m-1500w PA using a MRF1K50 in class AB:
945w  1398w dc  67% eff  453w disp
1511w  1888w dc 80% eff 377w disp

2m-1200w PA using a MRFE6VP61K25H in class AB:
566w  1200w dc 47% eff 634w disp
1133w 1542w dc 73% eff 409w disp

less heat dissipated when running full power RF ouput.
Both are W6PQL amps.

That's very high efficiency for a solid-state amplifier. Are they 
operating in class C? Are there any IMD specs at those output levels?

Hello Ed, I don't think that you are in class AB with 80% efficiency, in fact you cannot be.  Class B can theoretically achieve 78.5% but this is seldom achieved in practice, especially on VHF. Most likely there is a problem with instrumentation.

here is one i found and modified.
it selects Data a mode and sets filters regardless of present mode.
the one i found assumed it was always in data a mode but i use FSK for rtty
this made it work for me all the time.

Message-ID: <CAAa9j81f_ra9MbHfkGLQrunuePipBxphEJr1em7ivmSbq+1o4A@mail.gmail.com>

I am seeking information on how to configure the Elecraft remote software
for the KPA500 to work with a remote Startech 2 port serial server.   I
have been trying various combination of IP addresses and ports using a wifi
hotspot that is outside my home network .  Emulating what will eventually
be the setup when I move the KPA to my remote site.

I want to turn off the PC at my remote site to save power!

Can anyone help.  ?

I admit using FT8 :-)
FT8_ON: MD2;MN053;UP;UP;MN255;PC050;
Selects USB, switches the MIC input to Line-in, reduces power

FT8_OFF:MD2;MN053;DN;DN;MN255;PC100;

Btw, Dave, how did you manage to send commands to the K3? Does the P3
relay those commands over?

I use a Genovation Keypad, as described at:

https://www.nk7z.net/adding-external-keypad-k3/

As an example of just how versatile this is-- I tune in a DX station on 
the K3, then hit the SPOT button for a CW station to preset things.  I 
then press a single button on the Genovation, and the following happens:

1.  The P3 bandwidth is set to 6 KHz.
2.  The DX station is moved to the left side of the P3 screen.
2.  The 6 KHz above the DX station shows the pile up spread out.
3.  VFO B knob becomes the transmitter tuning control.

This allows me to find a hole in a pileup using the transmit cursor on 
the P3, tune to it, using the VFO B knob, and then I hit the "ID" macro 
button on the Genovation, this sends my call in the current mode.

This makes busting a CW or SSB pileup really fast and simple.  I hit a 
single button on the Genovation, (presets everything), move to a clear 
frequency using teh VFO B knob, then start hitting a second button, 
(sends my ID or launches a memory of my voice), till I get the station...

The Genovation is a 64 external keypad that plugs directly into the P3 
where the keyboard should go, no adapters, it just plugs into the P3.

This gives me 64 macro launching buttons, external to the K3/P3 
combination.  It is slick as hell to use...

I have macros for bandwidth control, mode setting, RTTY setup for the 
K3, (DATA A vs AFSK A), at single button press, Power control, memory 
launching, etc...

I have a spread sheet of all the above macros, and a few more at the URL 
above as well.

All the software that is needed save the Genovation itself, is available 
on my site.  Genovation has given me permission to distribute a modified 
version of their Genovation control software which runs in the 
Genovation keypad, and allows it to talk to teh P3 keyboard input.

You can get the Genovation via Amazon for around a hundred bucks...

Subject: [Elecraft] KXAT2 Memory Failure/Malfunction?
Message-ID: <C4A96ED4-FE9E-4195-AAC0-4AC44C5AE398@icloud.com>

Have owned KX2 #3007 for a little over a year.  I recently had to replace my at-home antenna because of weather (wind) damage.   I initially tuned the new antenna every 20 kHz through the 80/40/20m bands, and had no issues with matching on frequencies between tune points on first use (1.0-1.3 SWR)  Since then, the ATU needs to be re-tuned each use as the SWR on power-up is usually 25 or greater on the last used frequency.  Note that the antenna is disconnected when not in use.  Any ideas?

Keeping Watch-

I use an audio spectrum display - Spectrogram - to fine tune a barely there weak signal. Set tuning rate to 1 Hz - the APF peak is less than 10 Hz. Set the frequency cursor in Spectrogram to your pitch frequency. Set the DSP bandwidth wide so the NR works effectively ~ 700 Hz. Use NR mode ~m5-3 so the APF has some unprocessed signal to work on. It takes practice but works.

Duane,

important is to set fine tuning (1Hz) when using the APF as the only precise
tune on spot will effectively pulling out this weak sig from the noise. I do
not understand why the K3/K3S never got as same feature as KX3 > switching
to fine tuning automatically when APF is ON...

Also try to reduce RF gain (do not keep it at max) in order to reduce noise.

I have seen that when you need receive very weak signals, signals improve a
lot with AGC THR set at 15 (usually for a more silent reception I use THR
7).

The bias would do nothing for low power.
Low power can be implemented in two ways, with different taps at final
transformer (KX3), and with different supply voltage (Expert amps).  The
first one is hard at a KW level. The second one requires  power supply with
different voltages. If the power supply can deliver only one voltage, not
much can be done.

"What is happening. ?   How can I clear this from happening?"

Do you have anything connected to the KPA500 "RS-232 PC" serial port?? When my KPA500 went into loader mode I traced the problem (with help from Jack)?to corrupted RS-232 data that was being interpreted?as the KPA500 loader command. 

>From the Programmers Ref doc -?

"D? - download firmware
The D command is used to download firmware to the KPA500. This command is for Elecraft internal use
only. Accidentally issuing a D command may require a rear panel power off for recovery."

My notes say:

"D results in KPA500 displaying MCU LOAD. ? Recovery from accidental D requires rear power off, rear power on, then front panel power press."

In my case the corrupted data came from my Arduino based controller but I assume RFI could also cause the problem.

Yes I have a StarTech Ethernet to Serial port server attached to the RS232
jack.  I have been trying to get it to work with the amp so that I can get
rid of the PC at my remote.  Thanks for the solution.

Maybe there is something wrong with the server if data possibly corrupted . 
Have not been able to get the server working remotely with the amp

This would appear to be related to something connected to the amp either 
by the RS-232 port or the AUX port.?? To verify if it is internal, 
disconnect one or the other or both.??? Troubleshoot by progressive 
isolation, otherwise, one step at a time.?? Be suspicious of anything 
which is or may be communicating with the amp.?? If nothing is 
connected, an if the problem appears, it would likely be internal to the 
amp.? If it does not re-appear then it is something external.

While it is nice to have our stations fully automated and controllable, 
my motto is;? "more crap = more problems".?? I suppose it is just how 
much crap one is willing to endure.?? I prefer to keep my life simple 
and minimize issues.?? Which says less crap = less problems.?? Mine is 
connected to my K3S via the AUX communications port.?? I've found that 
to be 100% reliable.? I also have a RS-232 to USB converter connected to 
the RS-232 {PC} port with no issues.

Adrian,

if I remember it well there is ATU BYP or AUTO available in the menu only. 

With difficult loads you can tap ATU TUNE a second time within 5 seconds to
search for a lower SWR but manual tune function as it is available in K3 is
not implemented in KX3.

Modes L1-L8, C1-C8, and Ct are used to test the KXAT3?s relays and L-network
if I remember it well...

I have seen this also, and agree with Andy?s assessment. A program that polls the ports to find its target can also cause this issue.
Even though the KPA is displaying the MCU LOAD message, as long as no firmware data has been sent to the KPA500 and the firmware is actually not corrupt, you should be able to recover back to an operating state by powering the KPA off, then back on using the rear panel switch. 

I also have to mention that the KPA500 does a firmware check on power-on (when you push the front-panel power button). If that fails you will also get the MCU LOAD message. In this situation you will need to apply a fresh firmware update to the KPA to get it going. In your case the state was entered accidentally, which allows the power cycle to get you going again.

Good luck with the remote serial port. And be sure to describe what you do to get it going. There are several of us interested!

73!

It's probably worth emphasizing that the KPA500 is only vulnerable to a spurious "D" command when it is in "powered but off" state.   Perhaps the problem can be avoided by changing the sequence of remote station power up so KPA500 is only powered when the server is stable.  It may also help to limit the amount of time the KPA500 is in "powered but off" state.

Seeing what the server is sending may be useful.  I found my Rigol DS1054Z scope to be very helpful during my controller development.  When investigating my spurious loader issue I was able to capture the offending RS-232 data and see how it could be decoded as "D" even though "D" had not been sent by my code and was not present in the TTL signal.

This radio has very little time in use outside and is in great shape!  Price
is somewhat negotiable as similar listings have had some variance in prices.

 

Thanks in advance for your interest!

Here?s one way. 

You can send a string, say a letter ?T? (etc.) in CW mode with tone output only by embedding ?<? (RF off) and ?>? (RF on) characters in a KYtext command. 

For example:

KYW<T>;

The ?W? forces the K3 to complete the message send before moving on to other commands in the macro.

Hi Wayne,

Thank you for the suggestion!!

The software I use to send macros, (MixW), uses "<", and ">" to start 
and terminate a macro...

So no go...  Any other way to suppress xmit send a character, then 
re-enable xmit?

You could set power to zero, send the character(s), then restore power.

Hi Wayne,

Does the "W" suffix apply for all macro commands, or just the KY macro 
command?

Subject: [Elecraft] PS - reference level remembered by band?
Message-ID: <CAP6Pu4EoD3uGcKC3ZHab4+fDDzoo9zW--jB+XQAsZ+Eg1UZ-wA@mail.gmail.com>

I'd thought the P3 remembered different REF LEVELS by band.  But today the
same level is applied to all bands.

Is there a setting I should look for so REF LVL is remembered on a by-band
basis?

tnx,

Bill, K2PO

Good to know I wasn't the only one wanting to do this.  In my case I wanted to make my TS-590S beep if power was manually set above my controller's programmed band max power limit.  I force the power setting back to max and beep.  It was hard to find a way to make the TS-590S beep but I eventually found a CAT command that would beep but change nothing, AN999;.

If a rig has high and low tones for signalling to the operator it's unfortunate that there is not a CAT command dedicated to sounding those beeps.  Perhaps something to consider for the K4?

Message-ID: <4d3d0022-da4c-4ded-8261-a0f86d5f8984@www.fastmail.com>

Hi all,
I'm wondering what software solutions are available to provide an SDR band display, which incorporates Point-and-Click functionality that controls both the SDR and the K3 frequency?

In other words, identifying a signal on an SDR display and the action of clicking on that signal moves both the SDR and the K3 frequency to it.

I'm hoping there is one single software solution that incorporates both features requiring only one single USB interconnect into the PC.

Thanks
Duane

I use HDSDR which includes OmniRig to control my RSP-1A and my K3S.? It 
does provide point and click.? And best of all, it's FREE!

Here is a link to the correct drivers and such.

I was on the 20m frequency and listening and heard some traffic at 14050, but it too fast for me to copy. I had to leave to pick up my son from the airport before the 40m session began, so I missed that one. (I need a mobile rig in the 4Runner ? on the list.)

I started learning Morse a couple months ago and am progressing through the first CWOps class. I will begin the second class in April. I want to listen in on the Elecraft net and hope to join in the fun as my proficiency develops.

My solution might be unobtainium these days, but I use an SDR-IQ from RF Space 
and SpectraVue software. The SDR-IQ is no longer produced but they show up used 
from time to time. (I bought my third one a month ago)

Duane,

I've been using Win4k3suite along with a SDRplay RSP1A.? It works well.

I've been fighting getting the P3 for years. After trying to get SDR based
pan adapters to work reliably (I like the mouse point and tune feature) I've
decided I want to buy a toaster. 

Just plug it in and it works. 

A fully loaded 200watt P3 with video card..etc is hard to swallow when I can
buy a new HF rig with the Pan adapter built in for less. 

Are there plans to have a sale or bigger discount?

My time frame for purchase is March. I'll probably be going to the
Charlotte, NC Hamfest for the purchase unless I'm on call that week. 

Thanks in advance.

Yes, but the P3 plays so well with the K3 or K3S.? I know it is an 
investment, but I spent the bucks for the K3S, the P2, the KPA500 and 
the KAT500.?? There IS NOTHING finer and of better performance.?? The 
system integrates so well and smoothly it is thought of as one has a 500 
watt transceiver covering 160M through 6M.

I added my Down East Microwave transverter from my old EME station and 
now have 2M capability.? This required only 3 cables between my K3S and 
DEM 144-28 transverter.???? Again, just punch in the frequency and 
listen and talk.?? And the P3 shows what I want to see on the band and 
allows me to see a signal and its artifacts.?? You'd be surprised at the 
signals which have excessive opposite sideband noise and CW signals with 
clicks.

I have and have used a RSP1a with HDSDR software for point and click.? 
Nice, a challenge to configure, but does work nice.? The downside it 
requires a separate computer to support the operation.?? The upside it 
the software is FREE and the RSP1a receiver sells in the area of $150 or 
so.

Howdy Gang.

As the time for the Dayton Hamfest draws near I?d like to start the rumor/speculation/not-based-on-any-facts-at-all, sheer pipe dream for the announcement of a new Elecraft rig. 

It will be called the KX4?basically a KX3 on steroids with a 5? color TFT touch display that will cover 160-440 all-mode and will be the Elecraft answer to the Icom IC705.

Believe the KX3 is getting a bit long in the tooth so a new KX4 should be just around the corner.

Forgive me Wayne for letting the cat out of the bag (GRIN).

I?m a seer without peer (grin).

Hey, we can all wish, can?t we?

Been in the same situation, finally had luck and could buy a used P3 for
a reasonable price. Not fully loaded, but I can second it was worth the
investment. I played with different panadapters and SDR-software in the
past and have given up on this. The integration/configuration is not a
dream. Keeping the config stable with "plug'n'pray" USB-Soundcards isn't
fun.
The only thing I would like to see in the P3 is a smaller size given the
box is mostly empty.
73 good luck

That was my experience as well.  I initially had the LP Pan but later switched to the P3 panadapter.

The P3 in my experience is far easier to use under practical operating conditions.  You can widen or shorten the span to zoom in on a narrow part of the band, or zoom out to see across the band.  You can easily adjust to put the noise floor at the bottom of the screen and adjust the height of signals so it all becomes more easy to follow.    All of this can be done quickly with one hand.

I like my toaster and I don't regret buying it.

Given that the K4 has yet to be shipped, I?d expect that Elecraft is focused on getting the K4 finalized first.  Presumably along with the production headaches, there is also documentation, support infrastructure including customer support training, and web-based support tools.   With the actual release of the K4, there is also the question of variants being made available including the kit version.  I?m presuming that the ?behind the curtain? activities take up a significant amount of management time/effort that has nothing to do with ?playing radio'.  

Consequently, i wouldn?t expect any new product announcements this year other than updating the K4 product status and making a solid push in marketing/sales.  

That said, one can certainly hope for a KX4 that would address satellite operating interests, but my expectation is that such product development won?t be announced before 2021. By then Elecraft would be in position to decide what to incorporate from the K4 design effort  into a KX3 replacement along with having a better understanding of supply chain issues that will impact product production.  The delay in K4 release is due in part to logistics/production issues.

I can only imagine that Eric and Wayne whose passion for product development are being somewhat frustrated/challenged by the reality of bringing their creations to life.  Generals win wars with strategy, but it is the logistics that make it possible to implement in reality.

And don't forget that the P3 is actually an almost complete receiver 
(minus audio).? It just 'happens' to listen to the IF of the K3.

You can easily adjust to put the noise floor at the bottom of the screen and adjust the height of signals so it all becomes more easy to follow.    All of this can be done quickly with one hand.

Hi Joe

I think many of us will be happy to wait for the X-rated version and just get the K4.

That aside and as much as I would love the next iteration of the KX3, think its pretty awesome radio as it stands and mine has seen much use and many miles.

Everyone's setup and goals are different, but I can add my perspective on
this topic having owned an LP-PAN2 for years.  Plus I bought and owned a P3
with the VGA addon for comparison with the way I operate from my home
station with my K3S.  I also have tried both the RSP1a and the RSPduo with
the LP-PAN2.  Having spent time and money on all these solutions to compare
them, it was a simple decision to return to the LP-PAN2 using the ASUS
Xonar U7 to preset the I/Q output of the LP-PAN2 on screen for use on the
desktop.  Again, everyone has different requirements, so my conclusions
won't match with what other ops want from a setup. Here is what I'll
discuss.  1. P3, 2. SDRPlay SDR/RSP1/RSpduo etc.. connected to the IF
output of the K3/S, 3. LP-PAN2 with an ASUS Xonar U7.  The cliff notes
version here concludes that for NG7M, option 3 is clearly the hands down
winner for performance and desktop software integration.  Again, other
operators will disagree... I get it, everyone has different needs,
expectations, budget and patience required to understand and setup each of
these solutions.

1. The P3 with the VGA add-on daughter card: My most recent purchase out of
all these solutions was the P3 with the VGA addon board.  For an external
toaster setup, you can't go wrong here, it worked great but based on my in
the shack operating, contests and DX'ing, I never used it or even looked at
it while I had the LP-PAN2 setup running in parallel. But for plug and play
for someone that doesn't want to mess with software etc... it might be the
best solution.  It was simply clunky for me to look at the P3 display or
look at the separate dedicated monitor for the VGA output.  Plus no easy
point and click operating.  No integration at the desktop software level
using N1MM's spectrum display or a windowed output of the VGA adapter. (yes
I'm aware of VGA capture devices that could be used, but they bring a new
set of complexity to the table)  It was an interesting exercise.  I sold
the P3 after a few months.  It was just taking up space and most of the
time I never turned it on while operating in the shack, however it did look
nice sitting there when I looked at it while not operating. :)  Have I
missed the P3 based on the way I operate.  No... not at all.  All the while
I was using my LP-PAN setup side by side and I used the Spectrum display in
Win4K3Suite and while contesting fed the UDP feed from Win4K3Suite's
spectrum into the native N1MM spectrum... integrated spots and signal
detection for search and pounce... non of this possible with the P3.  So if
you want a turn-key setup and you want to look at a separate monitor with a
separate keyboard and mouse to poke around with the P3 output, it might
work great and it would work great for a DX pile up and just tuning around
and seeing what is going on, on the band.  It's the easiest setup hands
down and you can take the P3 remote very easily etc...  the P3 was simply
not for me and the way I operate.  Plus this is the most expensive solution
out of the setups I have tried.  If you don't want to mess with and tweak
an I/Q based sound card setup or external USB SDR setup, you might as well
stop reading and get out your credit card and buy this solution.  The P3
will always hold a pretty good resale value.  I easily sold mine for what I
paid for it a few months later and it's likely getting used now rather than
collecting dust in my shack.

2. SDRPlay SDR, i.e. an RSP1/a or one of the other flavors like the RSPduo
connected directly to the IF out of the K3/S.  This is an easy setup for
sure and I used it with Win4K3Suite's direct support of this solution.
Super easy setup and you get the native output of the Win4K3Suite spectrum
display which you can feed to N1MM's native spectrum display.  Why didn't I
stick with this solution?  #1 I had already see the superior performance of
the LP-PAN2 with a high end sound card prior to trying this solution.  I
couldn't handle the dynamic range blocking issues and the pumping spectrum
display in contests with strong adjacent signals.  The performance paled
into comparison with the LP-PAN2 and a Xonar U7 sound care.  For a
description and comparison of the dynamic range blocking performance of
the USB dongle SDR's in comparison to an LP-PAN2 pan adapter with a USB
soundcard setup, take a look at N8LP's measurements here:
http://www.telepostinc.com/dongle_comp.html    (likely needs some updates
on the cost comparison here) And yes!  Larry N8LP is bias here because he
sells the LP-PAN2 solution, but my experience and findings match the
numbers he shows... ~80dB of dynamic range with an RSP1 for example as
compared to 119dB with an LP-PAN2 Asus Xonar sound card setup.  ~85-85dB to
~119dB is huge and it shows when you have tried both solutions.  Plus the
SDRPlay SDR's use 14 bit DAC's as compared to a Xonar 7's 24 bit DAC. If
you want to investigate the difference here as it relates to SNR, wikipedia
has a good article: https://en.wikipedia.org/wiki/Audio_bit_depth  And yes,
there is a big difference between 14bits and 24bits, but bit depth doesn't
impact frequency response.  For me, the dynamic range performance with the
SDRPlay solution was a deal breaker.  I sold the RSP1 after a few weeks. (I
also own a newer RSPduo I tinker with but do not use for HF spectrum
display output while operating)  My conclusion, if you want a quick and
dirty spectrum display on the desktop in a window and integration with
N1MM's native spectrum display etc... this is a great option using
Win4K3Suite.  You sacrifice dynamic range blocking in a big way with this
setup.  The cost is ~$125 for an RSP1a and $65 for Win4K3Suite.  Yes I get
it... there are other free solutions for on screen output of the RSP1a.
But for integration in N1MM's spectrum via the UDP feed Win4K3Suite
provides and all the other feature / virtual K3 CAT port management
Win4K3Suite provides, it's a no brainer for me.  Less than ~$200 for this
solution if you are willing to sacrifice dynamic range blocking.  I have a
detailed YouTube video that shows the virtual CAT feed features of the
Win4K3Suite software, but I digress:
https://www.youtube.com/watch?v=zbf7BPfcj4U  Once you have tried option 3
below and have the patience to set it up... you will see why option 3 is
the clear winner for my style of operating in the shack. (your different
opinion is valid etc... it's all about your style and appetite  for eeking
out the best performance)

3. N8LP's LP-PAN2 connected to the K3/S IF output with I/Q output of the
LP-PAN2 feed to a high end USB sound card like an Asus U5/U7.  Okay, first
off... let's point out that Larry N8LP stopped selling the LP-PAN2 in Oct
of 2019 but is still fully supported.  This sad news, because I think the
issue here is that most guys are NOT willing to pay the price to setup this
solution and get it working right.  No pain, no gain is my conjecture
here.  This hardware setup with my K3S in conjunction with Win4K3Suite's
spectrum display and UDP spectrum feed support into N1MM is the clear
winner for me.  Hands down.  If are willing to do some research and take
your time with the setup here, you will be rewarded with superior
performance over the above solutions... including better performance than
what you get with the P3.  So until something better comes out with the K4
(yes I have a K4HD on order by the way), this is the clear winner for me on
performance and desktop software flexibility. The K4 and eventual desktop
software integration may convince me to stop using my LP-PAN2, but that is
down the road for now.  And before someone accuses me of being a fan boy of
Win4K3Suite let me say yes!  I'm a fan boy of Win4K3Suite and I have tried
the alternatives like NaP3... I used NaP3 a lot before Win4K3Suite came
out, but the CAT sharing in Win4K3Suite and the reliability of Win4K3Suite
is a hands down winner in my opinion compared to NaP3 and LP-Bridge for CAT
feed sharing.  That is a whole other topic.  If you are sticking with your
K3/S and not making the move to a K4 any time soon and you want the best
performance of an on screen / flexible spectrum display solution that
integrates with N1MM and or any other software supporting the UDP protocol
used by N1MM (including the need to feed your spectrum display output over
the internet), then this is the best setup I would recommend if you are
willing to read some documentation and get things setup / hooked up with
the LP-PAN2, USB Asus U7 and Win4K3Suite. (if you can't bare the $65 price
for Win4K3Suite, then use LP-Bridge and NaP3 or some other free-b software
for the spectrum output using I/Q output of the LP-PAN2 and sound card
integration.)  If you want performance and desktop flexibility and you are
sticking with your K3/S, find a used LP-PAN2 and hold on to it for the time
being.  I can already hear the whiners getting ready to start typing a
response... it's a no pain, no gain preposition here.  Do the research if
you are looking for the best desktop software integration and dynamic range
blocking performance of your direct IF output spectrum of your K3/S, then
my opinion and recommendation is clear... you buy three things, a used
LP-PAN2, an Asus U7 or U5 (I have only used the U7) and Win4K3Suite and
don't look back. And  you take the time to set it up right and understand
how the pieces fit together.  It's not my problem if you can't do the
research and understand the setup. And this setup should be usable right
out of the box when the K4 ships and will bridge the gap until native
spectrum data output on the K4 network interface is fully supported by N1MM
/ other desktop spectrum software.

Whew! Did anyone read all of this NG7M soap box drivel? :)  Max NG7M

Rick and all,

The P3 can listen to the IF of most any receiver, not just the K3.  Its 
input is tunable from 455kHz up to 21 MHz.

My neighbor K6XX put hand tools inside his on his journey to compete in

Consider that the P3 also has an IF output, so you can run the P3 along 
with the LP-Pan, SDRs, etc.  For those who want mouse QSY as well as the 
P3 display, that can be 'the best of both worlds'.

Hi,
I used the P3 as the reference standard in developing Win4K3, Win4Icom and
Win4Yaesu.
Useful tool but would be much better with a HDMI output.

FWIW: In General Eisenhower's memoirs of WW2 in Europe, "Crusade in 
Europe", a factoid is mentioned that it took ~700 tons of supplies each 
day to support a combat Division. The logistics to bring off D-Day were 
phenomenal.

Subject: [Elecraft] TCP Port for KPA500 and KAT500
Message-ID: <1581968245249-0.post@n2.nabble.com>

This may be a dumb question but here goes....

In the Elecraft remote software for the KPA500 and the KAT500 the TCP port
for the KPA500  is 4626 and 4627 for the KAT500.  Are these ports somehow 
"hard coded"  in the communications software for the two units?...OR can one
assign any port.  

I am thinking about the port forwarding that must be done in my remote
router as I am working on the installation of an Ethernet to Serial Port
server at my remote site.  Should I use the elecraft  port number in the
remote router to direct packets from the control end to the IP of the Port
Server at the remote to which the amp is connected....and vice versa to
establish the return path from the amp  to the router and control software 
at the Control end.

I hope someone can understand this better then the way I have described it.

There must be an interface box in between the network and the KPA500 and KAT500, since neither support network communications, only serial.

You might want to describe what you are doing and what devices you are using.

The interface is a StarTech NETRS2322P two port  Ethernet to Serial Port
server which will eventually go at my remote to replace the PC there that
currently runs the Host software for the KPA and KAT.  

TCP Port forwarding must be done in both routers to open the full duplex
path between the Control PC and the remote serial server.

What I am asking is:  should I use the TCP Port numbers that Elecraft uses
in their remote control software.?

Tom, aside from having to have an adapter tht would add in the audio, 
would one lose quality with a vga? to hdmi adapter. Never hooked up to

There is an RS-232 "dongle" that ships with every K3S. It has an RJ-45 
plug on one end and an RS-232 DE9 connector on the other end.
If you plug it in, change the switch on the KIO3B board (inside the K3S) 
to RS-232 and change the RS232 menu entry to 28400 baud, you can use 
that connection just like on the K3 - note that you will also use that 
same connection for firmware downloads and other K3 Utility operations 
(i.e. the USB connection will not be usable).

Sorry for the finger slip - thanks Ed - the baud rate is 38400.? You 
will not find 28400 listed, so it should be obvious.

Don W3FPR

-----------------------------------------------------------------------------------
There is an RS-232 "dongle" that ships with every K3S. It has an RJ-45 
plug on one end and an RS-232 DE9 connector on the other end.
If you plug it in, change the switch on the KIO3B board (inside the K3S) 
to RS-232 and change the RS232 menu entry to 28400 baud, you can use 
that connection just like on the K3 - note that you will also use that 
same connection for firmware downloads and other K3 Utility operations 
(i.e. the USB connection will not be usable).

It?s 38400 baud, not 24800.

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.

I live about 1.6 miles from some tall antenna towers broadcasting digital TV (KBCB) at 208 kW ERP on channel 19 (500 - 506 MHz) and on FM (KWPZ-FM) at 63 kW ERP on 106.5MHz - according to FCC info on KBCB and KWPZ-FM. Ever since I moved to this QTH a few months ago, I am unable to use my K3: solid S9+ noise on all bands using a makeshift dipole strung up on some trees outside my house. I?ve tried to locate the source of the RFI within my home but so far have been unable to locate any RFI emanating from within my home. Could it be that the TV/FM stations antenna towers, which are within direct line of sight from my house, might be responsible for the RFI?

One thing to try is an old-fashioned lowpass filter, such as used to be 
common as a measure against TVI. If the problem is caused by the TV/FM 
signals, this should help.

The K3's t/r switch can be overwhelmed by massive signals. I had such a 
problem with a 50 kW AM BC station that's visible from my antenna. I 
solved it by switching from vertical to horizontal polarization, but a 
high-pass filter also worked.

Have you tried pulling your main AC breaker and running your K3 on a car battery? ?That way, you are sure that nothing in your house (switching power supplies, poor mechanical joints, etc.) is creating the noise. ?


I was able to convince my nearest neighbors to shut down their AC panels also after my house seemed "clean". ?


I finally found 2 bad crimped power line connections down the street from my and a home made fence charge at a goat farm about 300yds behind my house through the woods. ?Another ham and the local power company came and helped. ?The power company did their work and it cleared up several S units, but something was still there. ?Riding around with a scanner tuned to 1800kHz (AM mode) with no antenna connected yielded the goat fence. ?The power company came out with a listening device to verify my findings. ?I offered to buy the farmer a fence charger from the hardware store, but he went ahead and did it on his own - it really helped having the power company there!!

I still have a neighbor with a noisy plasma TV - an MFJ-1026 with a longwire out the window nulls it out quite well when the TV in on. ?Eventually the TV will die (I'm hoping).

Good luck!

Good link! I could absolutely do that if I wasn?t working full time and earning a masters. I?d not get the keyboard functionality with a DIY card. 

I?m just not wanting to pay full retail for a legacy option (although I?m excited to get my P3 and VGA card). 

I?ll be picking up my P3 this week. 

 

I need to get over my key fright and get on the air a bit. Maybe Sunday  afternoon.

The SVGA option for the P3 is not a normal computer type VGA card.  You 
need the option designed to use the signals in the P3.

Amazon will be happy to supply you a doodle cable that converts the VGA to
HDMI.
If you have noticed that the newer idiot surround sound boxes won't play
your LP's or CD's you can get doodle cables for that problem too.

Always a problem when new standards change everything. Some one always has
a workaround.

None of these things hurts the pocketbook.

P3SVGA Video/FFT option in NOT a "VGA card" This is one of the 
most common misunderstandings about Elecraft products, partially a 
result of an uninformative Elecraft web site, poor marketing and a poor 
choice of part number that reinforces the widespread misunderstanding 
about the functionality of the P3SVGA option. 



The P3SVGA 2048 point FFT processor provides much higher frequency 
resolution per dot on a larger screen. The P3 built-in display has a 
480x272 resolution while the P3SVGA resolution is 1440x900.

The videos are excellent.  Ben Eater is one of the better teachers of digital electronics (especially to a philistine such as myself) on Youtube.  I built his 8-bit computer project almost two years ago and I am in the process of building the 6502 computer project (yes, my own Apple-1).

Even though you may not plan on building your own VGA (which Ben refers to as the world?s worst VGA) you should watch the videos to understand how Ben teaches an how VGA signals work.

Concur that a standard computer VGA card will not work here.  On the other had if you are referring to a pre-owned Elecraft SVGA option card that you buy used on the market I don't think that will be a problem, I am not aware of later generation cards and most of the feature upgrades are in firmware anyway.  If that is what you are thinking you might want to make sure by calling Elecraft.

The SVGA option works with almost any monitor for sale today that has a standard VGA plug connection.

While you are at it I would speak positively about the tx monitor option.  I have found that really useful to quickly verify my transmitter is operating properly and the microphone settings are ideally configured.   

I use my K3/P3 combination a lot in Field Day.  Things can go wrong in this setting, including disrupted antenna feed lines and antenna malfunctions.  In addition with multiple operators using the equipment you don't' know if someone has altered settings in some manner.  With the TX  monitor equipment you visually see what you are doing with every transmission.  You catch something going wrong immediately and can move to correct it.    You also know if no one is responding to you it is more likely due to band conditions or who is out there rather than your equipment.

The SVGA option for the P3 is not a normal computer type VGA card.  You need the option designed to use the signals in the P3.

P3SVGA Video/FFT option in NOT a "VGA card" This is one of the most common misunderstandings about Elecraft products, partially a result of an uninformative Elecraft web site, poor marketing and a poor choice of part number that reinforces the widespread misunderstanding about the functionality of the P3SVGA option. 

The P3SVGA 2048 point FFT processor provides much higher frequency resolution per dot on a larger screen. The P3 built-in display has a
480x272 resolution while the P3SVGA resolution is 1440x900. 

N6TV's web site is far more informative than any P3SVGA performance related information available on the Elecraft web site. See slides 11 and 12:

I can?t help with whether the ports are hard coded or not ? but I can give you a neat solution.

You can  use a low cost raspberry Pi with a couple of USB to Serial adaptors to link to the KPA500 and KAT500

The free software ser2net will give you a direct interface from the TCP/IP to the serial ports.

Configuration is pretty easy and basically two lines like 
4626:telnet:600:/dev/ttyUSB0:19200 8DATABITS NONE 1STOPBIT banner
4627:telnet:600:/dev/ttyUSB1:19200 8DATABITS NONE 1STOPBIT banner

You can connect to the TCP/IP side of the Raspberry Pi through WiFi or Ethernet from your main router, but  you would have to open those ports inside the router.

I run my KX3 remotely like that without problems ( higher baud rates work well for me )

I suspect the addresses in the remote software are fixed, or at least that is their default. With that in mind, if you want to use the remote software, then you probably should set up the ethernet serial adapter to use those specific ports. I?m not really familiar with how the remote software is set up, but I am sure we can ask.

Hope this helps?

HI Andreas

Sorry to hear about your noise.

I doubt your noise is related to digital TV as that is a long way away in
the frequency world.  It is pretty common to assume that it is not on your
own property.  I saw one guy who said the same thing and then found out a
year later it was his new dryer that was noisy even when they were not
using it.

I would not be surprised that most of your HF noise is within your own
property unless you did some significant research by  holding an AM radio
near each and every power cube or charger for phones, etc.  There are not
too many that are quiet.

I use my KX2 to find most of my HF noise issues and I must have tossed out
15 bad chargers.  The ones I could not just toss away, I had to add Mix 31
chokes to.

When you moved into your new house did you replace all the light bulbs with
LED bulbs?  They can be noisy.

If you haven't taken the time to do an indepth study on your own house, you
should.  You might be surprised.  I would plan an all day exercise when
everyone is out of the house.

Had a similar issue moving to a new QTH. It turned out to be a bad
transformer in the neighborhood. You could call in an RFI complaint once
you rule out your own QTH and asked them to sniff around.

You can also sniff around with a 2 or 6 meter SSB rig if you have one.

House we just moved into, we did new under-the-counter lighting.  Once I
got the ham shack started, I saw s9 noise on 160 and 80. Turn them off, and
it becomes quiet.

Other led panel lights produce no noise whatsoever.

But now that that is identified, I will be tracking down some other noise,
likely in the neighborhood.

Have you inquired at a local ham radio club for help with your RFI/EMI 
issues for assistance in finding the problem?

I doubt? transmitters 1.6 miles away would create problems for you.

Yes, I did run the K3 off of a battery and pulled the main AC breaker. Didn?t make any difference. Thus my suspicion that the RFI is related to the 208 kW ERP TV station (and/or 63 kW EPR FM station) which are within 1.6 miles and in direct line of sight.

Another ham and the local power company came and helped.  The power company did their work and it cleared up several S units, but something was still there.  Riding around with a scanner tuned to 1800kHz (AM mode) with no antenna connected yielded the goat fence.  The power company came out with a listening device to verify my findings.  I offered to buy the farmer a fence charger from the hardware store, but he went ahead and did it on his own - it really helped having the power company there!!

One of the first things to try is to operate the station receiver from a 
battery, disconnect everything including the external ground,? but the 
antenna.? Then drop the mains breaker to the property.? If the noise 
changes, then some or part of it is on your property.? If the noise does 
not change then it is most likely not on your property.? Don't forget 
about any UPS that you may have on the property.?? It must be turned off 
as well.? Our fiber internet service has a battery back-up at the 
demarcation. You may need to unplug that unit as well.

If it is not on your property, I suggest a portable AM radio tuned to 
1700 or such if there is not local station on the frequency.? Most of 
those radios have a rod antenna that is bi-directional.? Use it as a 
null device as the null will be much more pronounced than trying to peak 
the noise.?? Headphones or earbuds will help. ?? You'll need a local / 
sub division map. Mark the axis of the radio on the map,?? then move 
over 100 to 300 yards to the side and do the same.? Usually 3 or 4 sites 
will have the lines intersect.??? You can then move to that location.? 
Worst case, should you have 2 or more noise sources which are then a 
real challenge to chase.

If it is on your property, then drop every individual breaker, bring the 
mains back on and observe.? Then add one breaker and observe.? Add the 
next breaker and observe.?? Finally you will find the 2 or 3 that 
contributes greatly to the noise.? Then you can check the devices on 
each one.?? Don't forget about the doorbell transformer.? Those go bad, 
make noise, yet the doorbell will still work.

Once the location is known, then contact the property owner or the local 
utility.? You may have to be persistent with the local utility, move up 
the chain of command,? but diplomacy along every step goes a long way to 
getting something done.

It is also worthwhile to note the day and the times the observations 
were made.? It could be related to something only furing the day or only 
at night or maybe on each Wednesday and Friday? etc.

I doubt it is anything from the TV stations.

Does the noise appear on one band or several bands?? Is it tune-able 
thus limited to one broad frequency or just total broadband noise?

You will need to know the frequency of both transmitters and then 
perform an IM study.? The sum of those two frequencies is doubtful but 
the difference could be fall in the ham band(s).? You can contact the FM 
station and the TV station engineering department and inquire as to when 
they have transmitter maintenance scheduled.? What ever day or hour of 
the night that might be, you need to be listening. ? If it doesn't go 
away, it isn't them.?? If it does, that doesn't assure they are at 
fault.? I've seen chain link fences make a nice diode junction and it 
radiates like crazy.

Here is a link that will simplify the calculations.

With a K3 with upgraded IO, I am getting distorted recording audio using
the USB CODEC. This used to work. I don't know what changes were made to
screw it up. In my SO2R setup, the other radio records perfectly. I can't
find any menu entry differences.

It?s a whole different audio chain. 
Now the ADC is in the radio, not the computer.

Bill,

 

When Ken mentions his SO2R setup, that means two radios (inferring both are
K3) and he is saying his other radio is working perfectly so he understands
that the rig has an audio codec built into both his K3 rigs (probably why he
got the upgraded I/O board). One has a distortion problem.

 

Ken,

 

Have you tried uninstalling the CODEC showing in Device Manager and just
reinstalling it?  Also, maybe the CODEC properties got scrabbled somehow and
each CODEC has different properties?  Just guessing from memory since I
don't have a rig here to look at.  Everything is at the station.

 

Good luck tracking it down. 

 

Bob K5WA

We bought a new Keurig coffee maker which does a pot or also the pods. It puts a huge noise out to the ham frequencies. Have to turn it off to get on 80M

Hi ,
I have a K3S and P3 with VGA card to run another display and was expecting to see a duplicate of the P3 screen in larger format. It?s true I can see the waterfall and data decode, but not seeing the tx signal status. If this is its limit, I?d probably say the vga card is unnecessary. 
Running a low cost sdr and the software to drive the K3 from the PC works well though. 
Vy pleased with the K3S, but a tad disappointed with the P3 TBF.

Yes, I did run the K3 off of a battery and pulled the main AC breaker. Didn?t make any difference. Thus my suspicion that the RFI is related to the 208 kW ERP TV station (and/or 63 kW EPR FM station) which are within 1.6 miles and in direct line of sight.

John

This solution is interesting to me since I already have the two USB-Serial
cables in use with the remote PC.
That PC hosts the Elecraft remote software.  Only problem is I know next to
nothing about Linux.  I have a spare PC that I could convert to LINUX
but I need to start from scratch!

Thanks for your suggestion and I will consider it .  I am going to try and
make the Serial server work first and have to take it to the remote site as
soon as
weather permits!

I recently had an intermittent high noise level on 6 m band and there seemed to be a correlation with activity at my neighbors house.  I ran a PC application that showed my transceiver's S meter and remoted my PC desktop to my Android phone with TeamViewer.

Next time my neighbor was working in his garage, and the noise was present, I went over and explained my noise problem.  I asked him him to shut off his garage lights one group at a time while we monitored the noise level on my Android phone.  The noise was traced to one group of florescent lights and was completely gone when that light group was disconnected.

I think it was a big advantage to be able to show him there was a direct correlation between my noise level and his lighting.   He agreed to keep that light group disconnected and said he would replace them later.   Just a few days after resolving the noise problem I worked Alaska to complete 6 m WAS.

Andreas,
You might want to go to the station and talk the the Chief Engineer. If he 
is the nice-guygal type CE he will help you (Not al CEs are the nice kind 
but most are).

I'd suggest that he/she cycle the two transmitters on/off while you are at 
your station. He/She won't do that during the early news but might at 2 or 3 
AM. It is worth a try.


Long ago - I had the opposite issue when ham transmitters interfered with TV 
receivers. Some people call the TV station to resolve the issue. Most of the 
time it came down to who was going to buy the filter. At any given time we 
probably had 10 filters on the shelf.

One point - TV (especially UHF) antennas tend to fairly high gain. The 
pattern tends to be omnidirectional horizontally. The gain is in the 
vertical plane. Much of the transmitted power is well above 10? (probably 
much higher). The FM antenna gain depends on the size transmitter. Usually 
they tend to use lower gain than TV antennas.

In a spectrum analyzer - the digital TV looks like high power noise. The 
signal should square corners on both ends of the occupied spectrum.

I live about 1.6 miles from some tall antenna towers broadcasting digital TV 
(KBCB) at 208 kW ERP on channel 19 (500 - 506 MHz) and on FM (KWPZ-FM) at 63 
kW ERP on 106.5MHz - according to FCC info on KBCB and KWPZ-FM. Ever since I 
moved to this QTH a few months ago, I am unable to use my K3: solid S9+ 
noise on all bands using a makeshift dipole strung up on some trees outside 
my house. I?ve tried to locate the source of the RFI within my home but so 
far have been unable to locate any RFI emanating from within my home. Could 
it be that the TV/FM stations antenna towers, which are within direct line 
of sight from my house, might be responsible for the RFI?

Andreas, TV transmitters at 500 MHz +- are really not noise disrupters in our amateur HF world. In fact, in our AREDN mesh work in LA, we?ve found that Ubiquiti sector antennas at 3 GHz and 5 GHz producing just milliwatts of power play nicely next to commercial TV transmitters generating 1.5-million watts at 500 MHz. So it?s something else.
A few years ago, I was on a similar RF noise hunt in my systems which reside in central LA, an RF noisy place. Some things I learned:
1) Pay close attention to how your power supply is connected. Use shielded twisted pair wiring from your power supply to your radio, and do not use red-black zip line. Unless twisted, that untwisted cable becomes an excellent antenna delivering noise to your system. In fact, pay attention to all cables. Make sure they are shielded. 
2) Hunt for noise makers. At that time I made the really dumb mistake of having two touch lamps near my radios ? ya know, ya hit the base to raise or lower brightness. Those things will make noise for miles. Away they went.
3) Older plasma flat screens (pre-LCD) are noise makers. Most light dimmers. Someone even had a coffee maker with a loose heating coil connection that was through the roof with noise.
4) In my hunt for noise makers, I used an aircraft band hand-held receiver (that?s AM), squelch off, and just walk around touching the antenna to things.. Eye opening. Ya know what my biggest noise maker was near my radios?! My D-Link switch which lives under the desk not 3 feet from my HF radio. Further all of those CAT6 cables were great little antennas just spreading that noise all over. Solution: feed the switch highly filtered power and change all cables to CAT7 which is heavily shielded CAT6. Made a big difference.
5) Ferrite beads, clamp-ons. Get a bunch. Put them on every cable. Double up on the coax. Keep standing waves away. You want to discourage RF from traveling in places where it should not go. Ferrites are wonderful. Get 'em on Amazon.
6) Grounding. There are several well-known AC filtering devices that can add an extra ground to your AC mains coming into your radios.
7) Switching power supplies. Those wall-worts. Noisy beasts. Best to use a centralized, filtered 12V DC system that eliminates those wall worts altogether. One of the worst noise makers near my radios was a lovely, beautiful LG display which could not be plugged into my highly filtered and shielded 12V DC system because they run own 24V. Switched it out with a nice Samsung which runs on 12V and it runs totally quiet.
Good luck. The hunt may take a while But these steps took my urban noise from S7 to S1. Was worth the time.

FWIW: We recently gave up the grinder, we found that the very fine

whole beans in our grinder.

Maybe in 1960, but no way in 2020. Besides, it is quite unlikely that 
these stations are causing your problem, but as has been observed, a 
simple LPF inserted in the antenna will prevent those TX from hitting 
your RX.

George is right on about antenna directivity and the spectrum analyzer 
display.

As I observed earlier, the FAR more likely source(s) of your noise are 
dozens of switch-mode power supplies in your home and the homes of each 
of your neighbors, other equipment that includes power control 
electronics, and equipment that includes microprocessors.

This link can query the FCC website to see technical details for any 
broadcast station in the US. https://www.fcc.gov/media/radio/am-query

Hello Everyone,

I'm getting the following error codes on 80 meters, 160 and 40 are working.

I suspected the 80m antenna so I tried using a dummy load and I get the 
same error codes.  Reducing the input power does not help.

I've reloaded firmware 2.38.

Anyone run into this problem?

Presuming that is a known 'good' dummy load for that power level, have 
you run the output calibration of the driver radio (K3/S also presumed) 
as a starting point?

If that has been done (successfully, multiple times), check to make SURE 
that the radio (driver) antenna tuner is BYPASSED (not presenting an odd 
load into the amp).

Watch CAREFULLY that the driver output is constant (no dirty control, no 
spike etc.).

Then it's time to be concerned about the 80M tuned input circuit failing 
on the KPA1500 and call Elecraft for specific tests.? When the amp sees 
 >=19 watts input, it wigs out, badly.? (But the extreme outputs ARE 
impressive; it's nice to have overhead at legal limit).

GL, please let us know how it was resolved,
Rick NK7I

Sounds like an issue with the power detection circuit on the filter board. I had the 3 watt resistor unsolder itself from the board (it is mounted upside down so gravity helped). I had all kinds of weird power reading issues that were impossible for the input power and current draw.

I suggest calling Elecraft before doing anything else as you can cause more damage continuing the transmit. Elecraft was excellent in diagnosing my problem and sent me the necessary parts to repair it in the field (I did work in electronics, so familiar with surface mount work)

Subject: Re: [Elecraft] KPA1500

Presuming that is a known 'good' dummy load for that power level, have you run the output calibration of the driver radio (K3/S also presumed) as a starting point?

If that has been done (successfully, multiple times), check to make SURE that the radio (driver) antenna tuner is BYPASSED (not presenting an odd load into the amp).

Watch CAREFULLY that the driver output is constant (no dirty control, no spike etc.).

Then it's time to be concerned about the 80M tuned input circuit failing on the KPA1500 and call Elecraft for specific tests.  When the amp sees
 >=19 watts input, it wigs out, badly.  (But the extreme outputs ARE impressive; it's nice to have overhead at legal limit).

GL, please let us know how it was resolved, Rick NK7I

Subject: [Elecraft] P3 Goodness and questions
Message-ID: <034901d5e7fe$73b181a0$5b1484e0$@carolinaheli.com>

I recently obtained a P3 and I'm and exceedingly happy! Now that I own it I
feel bad that I wasted a few years trying other solutions that introduced
noise and undue complexity into my station. 

Just a few notes and questions because the manual is helpful but I don't
fully understand what I'm reading yet. 

 

1.	When using QSY the P3 unit often slides. How do most of you prevent
the unit from sliding?
2.	The signal/noise floor jumps a lot and I'm not sure if that's due to
local interference or something in my setup. Based on reading I likely need
to noise troubleshoot/filter my station. I don't see an AGC setting for the
P3. Any suggestions?
3.	What serial number requires the mod? My serial is 3251
4.	I need a serial port screw stud - can I buy that from Elecraft when
I purchase a cable + vga card?
5.	Is there a quick setup cheat-sheet anyone has for the P3?

 

Thanks in advance

Message-ID: <0DC1A712-ACD5-4164-8B7F-6122A2FD59E5@newgas.net>

Setting up the KX3 Pre-Amp for FT8/JS8Call when receiving ?
I use my KX3 mainly for JS8Call and FT8 on 20 and 40m.    Because I live in London, I have a poor antenna and quite a lot of QRM around me.

I had thought that my KX3 might be a bit deaf on receive as my 10W signal can be heard by many stations which I can?t hear.  Before making and erecting a new antenna, I thought I would re-check all the settings I use  ? Attenuator OFF, RF Gain set to 0 etc.

I then started to think about the receive pre-amp which is normally OFF.  Setting ti to 10 db Gain and turning it on, did seem to improve things.

I was wondering how with Digimodes to work out the best level for Pre-Amp gain.   The traditional "listening for signals in noise" doesn?t really work as the detection levels are below hearing.  Any good suggestions for setting this optimally when you have a short and poor antenna ?

Do you have neighbors? Did you pull their breakers at the same time?

Do you have a UPS? They continue to run without power, so both they and 
any connected equipment can create noise.

Did you take the time to study the link I posted?

I once had a noise issue and I used my KX3 roving about the neighborhood to find it.  Actually, I found a number of loud noise sources doing that as I moved around.  It seems that if the noise level is fairly constant as you move around the area but will within the same general distance from the TV/FM station antennas you could isolate the source as those antennas or something else.

Andreas:? The probability that your noise is due to the TV or FM station 
is extremely low [like really zero]. Meadow Lakes CA is the "TV/FM 
capital" for the southern Central Valley [Fresno], and my 2m HT goes 
full bars about 2 miles from the complex on both FM and AM [aeronautical 
band].? When at the repeater site next to a 300 KW digital TV station, 
my comrade's HT won't break my squelch.? It is just front end overload 
from way out of band, there is no discernible noise.

The number of noise makers we normally see in urban/suburban areas is 
almost countably infinite.? In addition to the 24/7 constant hash from 
SMPS, I have a variety of intermittant noise sources that come and go 
with periods ranging from a few seconds [probably the A/C motor starting 
at the gym behind us] to an hour or so. One is a sequence of 
synchronized carriers on the waterfall about 7 kHz apart that last for a 
few seconds and then burst into roman candles that fog up the WF and 
then fade in 2 or 3 seconds. Neighbor 4 doors down the street just 
installed rooftop solar which I can now see on the P3 on 160 and 80. [:=(

K9YC's RFI notes pretty much cover searching for and fixing RFI.

It's really important to make sure you're listening to the right source. 
One way to do that is to listen to the audio from your home receiver (AM 
mode, AGC off, RF gain backed down to avoid overload) while you are 
searching. There will be a pattern of fluctuations. When they match, you 
have the right source. You can relay the home receiver by phone, 
VHF/UHF, etc.

Not so fast. The K3's T/R switch can be overwhelmed by very strong 
signals. The result is intermod junk all over the bands. This happened 
to me with a 50 kW AM BC signal at about 1000 kHz that is line-of-sight 
to my antenna. I don't see why a super-strong VHF signal couldn't have 
the same effect.

AM BC signals are far more likely to cause issues because 1) they are 
much closer in frequency (as a percentage) than VHF/UHF, so 2) our 
antennas tend to be far less efficient receiving them, and 3) feedline 
loss is high at VHF/UHF, due both to normal increase in loss with 
frequency and because the feedline is poorly matched to the RX at 
VHF/UHF. Also, AM BC transmitters often combine in non-linear junctions 
to produce IMD that ON_FREQUENCY in our bands. I first experienced this 
more than 60 years ago, when local 5kW stations on 930 kHz and 1470 kHz 
put a monster product on 3870 kHz, wiping out the WV AM net on 3890.

The IM often occurs in the TX output stage; because FM and TV TX 
antennas are often in close proximity to other BC and 2-way TX sites, it 
is common for these TX to include a device called a "circulator" that 
prevents signal from another TX to backfeed into their own output stage, 
where rectification can occur, but it is far less common for AM stations 
to include comparable networks. In addition, of course, rectification 
can occur almost anywhere.

I built a special clamp that goes over the top of my K3 and 
keeps the P3 on top from sliding backwards out of aluminum bar. 
Tightening the screws on the both ends clamp it to the K3 so it 
doesn't slide. It also comes off easily for getting into the K3 
and doesn't mar the K3 case.

My P3 sits beside my K3S and both use the elevation bail to raise the front of the radio and P3 along with my KPA500.  I don?t find that any of the 3 pieces move when operating.

Many years ago I took a piece of oak the same length as the combined width of my K3 and P3.About 1" thick by 3" wide.On the 3" face I created a groove running the entire length set back about an inch from one edge.The dimensions of the groove are such that the rubber feet on the bails on the radio and P3 are a snug fit.I added some self adhesive feet to the bottom of the wood piece.Keeps the K3 and P3 in perfect alignment with each other.I rounded the edges and finished the wood with polyurethane.?Looks really nice and I could probably make another in less time than it took me to write this email.73,Gary K9GS

Subject: [Elecraft] A question about HDSDR controlling SDR & K3 at same time
Message-ID: <4eef20e3-e141-4d62-86a8-75a3cc00550c@www.fastmail.com>

So last week with your help I got HDSDR setup to control both a RFSPACE-IQ (for panadapter) and the K3 at the same time.

There is one behavior I haven't been able to figure out.

I have HDSDR and the K3 both setup to output a CW sidetone at 600hz.

In CW mode - HDSDR displays a close-up of a given signal on the lower-right.
And at dead-center its spot on - and producing the 600z tone.
But its then not quite spot on - on the K3

I've tried offsetting the side-tone frequency on HDSDR - thinking I just needed to shift it so that when the K3 is spot on - the signal will show up in dead center on the HDSDR signal window.

But that doesn't seem to work.  It still retains the exact same frequency offset between HDSDR and the K3

Has anyone seen this?
And can suggest a fix?

Thanks
Duane

You will need to correct the frequency errors using HDSDR calibration mode. There is a setting for each mode.  It is in the Setup menu under input calibration.

Thank you Bob!
Yes I see it - its the "RF Front End + Calibration dialog box".
And the "LO Freq Cal"

I've got it setup correctly now
Thanks!

Depending on the stability of the oscillator in the SDR, the numbers you 
have now may be good, or may change.?? I have an early RSP1a and it 
moves around a good bit.?? I don't rely on it for any degree of 
accuracy.? I think it is more temperature related than anything.

I have used a rubberized mat material designed for lining kitchen shelves to keep keyer paddles in place. That may work for a P3 as well. Something like ?gorilla grip?. There are a number of choices.

Yes. My K3s are tilted with the standard bale, and I've used velcro tabs 
applied to the top of the K3s and the P3 feet. Not elegant, but it works 
fine.

Elecraft is a small company, like most amateur companies.  :)

It may take a day or so, but they will get back to you.  There are likely
other customers in front of you.

Yes, I do have three neighbors: two are about 550 ft away and one is 700 ft away. I have not asked them yet to pull their breakers. I thought the distance was far enough to eliminate RFI from household appliances, plasma TVs, etc. Also, the RFI is 24x7 so if it were caused by my neighbors? plasma TVs, there shouldn?t be any RFI at, say, 3AM in the morning. There are no electric fences in our area. I do have a UPS. I eliminated that as the source also.

RF overload can do a lot of things.
Try above and below 12W (8W on 6m) to see if the KPA3 is swamped.
Or an antenna on the RX port (If KXV3 equipped).
Also RF overload can excite any loose connections at the tower site, 
rusty metal, fence joints etc.
You are just going to have to sniff around with a portable setup.

Message-ID: <0805F438-3D4F-4B80-A3A8-6594E9F1B1EF@comcast.net>

I am running my K3 Mini to my K3S via wireless.  I am running into a strange issue.  Every time I go into CW mode I am getting a ringing noise. I can get rid of the noise by changing the RF Gain.  The thing I am wondering about is I am not hearing any CW signals on 20m, 40m or 80m.  I am just wondering if there is something I have set wrong.  I am also wondering if the RF Gain is set properly.  I know this question is a little vague but I am in the last stages of getting this remote setup working well.   Any suggestions would be greatly appreciated.  Thanks in advance.

I've had several of the inexpensive Keurig Pod type, and have never had an issue on any band.

Kitchen is right next door to the shack, and the pot is on all day.

I still love the coffee maker and would buy it again. I just turn it off after the pot or pod is brewed.

I have 24xx K3. It did need the mod. Actually put in when I had a LP 
pan-adapter before the P3.
The mod is changing one resistor. R8 from 1k to 13k. I used a 1/4 watt only 
because I do not stock 1/8 watt.

On the Elecraft web site K3IOBUFFKT - IF Output Buffer Gain Modification is 
the kit for $5.
https://elecraft.com/pages/k3-enhancements-and-mods-and-tech-alerts

The instructions are 
https://ftp.elecraft.com/K3/Mod%20Notes%20Alerts/IF_Output_Buffer_Gain_Mod_Rev_A.pdf
The mod sheet says all K3 shipped after September 2009 have this mod.

Hopes that helps a bit

Subject: [Elecraft] P3 Goodness and questions

I recently obtained a P3 and I'm and exceedingly happy! Now that I own it I
feel bad that I wasted a few years trying other solutions that introduced
noise and undue complexity into my station.

Just a few notes and questions because the manual is helpful but I don't
fully understand what I'm reading yet.



1. When using QSY the P3 unit often slides. How do most of you prevent
the unit from sliding?
2. The signal/noise floor jumps a lot and I'm not sure if that's due to
local interference or something in my setup. Based on reading I likely need
to noise troubleshoot/filter my station. I don't see an AGC setting for the
P3. Any suggestions?
3. What serial number requires the mod? My serial is 3251
4. I need a serial port screw stud - can I buy that from Elecraft when
I purchase a cable + vga card?
5. Is there a quick setup cheat-sheet anyone has for the P3?



Thanks in advance

I am experimenting with an excel spreadsheet as a way to log the stations checking in to the net. I am hoping that I can post them to the forum without problems. I will try to do this for this week's net. 
Thank you to the relay stations as conditions were up and down during the net. The net meets at 18:00Z. on Sundays on a frequency of 14.303.5 and all are welcome to participate in the net.

Andreas,

For at least ten years, almost anything we buy that plugs into the wall 
has an SMPS that generates noise as long as it's connected. This 
includes everything from computers to TVs to home entertainment systems 
to battery chargers to the inverters for solar systems. My closest 
neighbors are at distances about like yours, and I get noise from them. 
Some of it cycles on and off, some is constant. There's power line 
noise, which can be constant or not.

Like the technically illiterate folks who live near me who believe that 
cell towers cause cancer and who campaign against the addition of cell 
sites that can provide us service, you've made up your mind without 
knowledge of the underlying science.

I've sent you a link to a tutorial that provide detailed advice about 
figuring out what kind of noise source(s) you have, how to track them 
down, and how to kill them. I repeat my advice to study it.

What matters is distance to antennas, not the shack. The nature of 
electrical wiring in your home also matters, because it's that wiring 
that radiates any noise produced.

(Sorry about the previous blank message -- this is now the ONLY
mailgroup I'm subscribed to that refuses HTML-formatted mail, which is
the default setting for my mail client).

It's amazing the things that can cause issues.  From my experience:


1) An automatic porch light sensor, the kind that screws in the light
socket and then you screw the porch light bulb into it.  It was putting
out broadband hash across several bands, but only at night, when the
light was on.


2) A Mr. Coffee coffee maker that had a little LED clock in the base, so
you could set it to auto-brew in the morning.  That little clock also
put out broadband hash, whose tone tended to vary somewhat depending on
what was currently on the display.  I had to find it using a portable
radio and finding that the kitchen outlets were 'singing' with the
signal.


3) A doorbell transformer, that was mounted on the side of a light
junction box in the basement, located above a false ceiling panel.  The
really annoying aspect was that the transformer didn't seem to be on any
branch circuit.  I finally discovered that the previous home owner had
jumpered a couple of branch circuits in the breaker panel (?!), so
turning off only one of the breakers didn't kill power to some outlets. 
This circuit was shared with the kitchen dishwasher, etc. outlets, and
apparently they had had breaker trips from the overloaded circuit, so
they just jumpered another breaker in parallel.  After running
additional circuits to put the dishwasher and garbage disposal, etc. on
separate circuits (and removing the offending jumpers in the breaker
box), I was finally able to isolate the doorbell transformer, which was
subsequently replaced.


It's been a while since I've done a 'whole house down' survey, and my
noise floor has crept up again.  In particular, I have a broadband noise
that is 20 over S9 that wipes out the top half of 80 meters and all of
60 meters.  I suspect it is my neighbor's U-Verse system twisted copper
pair uplink which operates on those frequencies.




"The second band is used in upstream and start at 3.75 MHz and end at
5.2 MHz " -- https://adslm.dohrenburg.net/uverse/


It's a never-ending challenge...


Good luck, and 73,

This is the newest one that brews a carafe of 10 cups or does a pod into your mug. I too have had others without any noise, but this new one puts a huge sine wave of noise on the panadapter. I have put ferrite on the line cord which don't affect it. I just turn the thing off after brewing...or wait about 5 minutes and the noise goes away.

Which ferrite? There are dozens of different types. Did you just clamp 
one on, or did you wind multiple turns through it as shown in these links?
http://k9yc.com/KillingReceiveNoise.pdf and
http://k9yc.com/KillingRXNoiseVisalia.pdf

If you don't use the "right" ferrite and if you don't wind the "right" 
number of turns for the band(s) where you hear the noise, the ferrite 
WON'T do anything.

That's about what I paid for mine, without the hat. Got my hat with a P3 and a tour. A $900 hat instead of a $1200 hat.  Bargain.

I don't know the mx. I get it though, it's worked on switching supplies and I wind multiple turns. They did a great job on a treadmill. A different mix may be better because it seems like a lower frequency.

Seems like a good reason not to buy one.  Which reminds me, do they have a Part 15 label attached?   Not that they actually meet Part 15 requirements.

Well, Jim - 

If you're going to quote someone, bear in mind that editing what they said
out of context might change the meaning of what they said (you've probably
heard of the C.O.M.A. process used in Bible study).

I said two things:

1) I've had several of the inexpensive Keurig Pod type, and have never had
an issue on any band.

and ...

2) Kitchen is right next door to the shack, and the pot is on all day.

#1 is a response to the RFI issue, but ...

#2 is an indicator that I need to have coffee nearby both for myself and for
others who may be visiting my shack. Stop over the next time you're in
Chicago.

73
Lyn, W0LEN

PS - FWIW, the nearest point of the antenna is probably 50 feet from the
coffee pot.  In Chicagoland, all wiring must be in conduits, and both the
kitchen and the shack are on their own circuits.  In fact, the only 'home
grown' RFI I am aware of is 1 out of 4 identical HP 24" LED monitors that
puts out a steady carrier on 30 meters.

What matters is distance to antennas, not the shack. The nature of 
electrical wiring in your home also matters, because it's that wiring 
that radiates any noise produced.

There's a paragraph of slightly raised writing on the bottom...really hard to read, but if I get a chance to turn it over again, I'll check. It's set up for morning right now.

Is there a way to limit the audio output on the K3s to prevent sudden loud
signals from causing hearing damage? This happens in CW contest operation
and I've adjusted the AGC to minimal threshold and slope without any
significant effect. Are there any other adjustments in the unit itself? Has
anyone used an external device between the K3s and headphones to accomplish
this? If so, what device was helpful?

Thank you very much Keith and Don. Until today I haven?t had time to review
the possible failures.
I have checked and the D37 is failing so I am going to replace both D36 and
D37, what kind of diodes should I buy to replace them?
I have also checked the rest of possible and failures and everything seems
ok.

After about 100k QSO this is second fault, firts changed the pin in the back
panel about the 12 V error problem.

K3, great rig.

It could be D36 & 37 on the RF board. Earlier ones (1st few thousand) 
had weak components. But any of them can fail and usually there is 
runaway power out.
If that is not it, look for burned components under the KANT3 board 
around T4 or on the underside near D36 & 37 look for burnt traces.
If it is older than about #5500, it could be front panel tin pin 
oxidation, replaced them with gold.

I use Excel a lot!  But, I would never consider using it as any kind of
logger.

A very popular on-line program for net logging is NetLogger:

https://www.netlogger.org/

I recommend you check it out.  Several groups I frequent use it.  One cool
feature is it's on-line so one net session can have multiple users.

Scott, N3FJP, of Amateur Contact Logger fame, has a net logger:

http://www.n3fjp.com/otherprograms.html

That may suit your purposes better, especially if you don't want the on-line
capability of NetLogger.

For #1 there are a couple of things a) in menu set one of the function 
buttons to "knob tap" and "knob hold" the select knob takes more 
pressure so using one of the function buttons is much less force. b) I 
have my K3s and P3 mounted to a single board, I put the bails down and 
then built a couple of simple clamps to clamp the bails to the board, 
makes the K3s/P3 combo a single unit not only keeps the P3 fixed but 
also simplifies cabling so they act as one unit when needing to move 
around. Kinda like having a large K4 :)

#2 go into the menu and turn the Noise Blanker on "NB En", you may have 
to experiment with the NB Level (I set mine on 5) depending on your own 
conditions.

Having lived in Chicago for 42 years and maintained an engineering 
consulting practice there for 30 years, and as a former member of IBEW 
134, I'm well aware of the conduit requirement. :) Indeed, I had a lot 
of conduit installed in the 2-flat I bought on the North Side in 1986. 
Which is also why I added the phrase "the nature of electrical wiring in 
your home also matters." The large sound systems I designed and 
specified used miles of conduit for both power and signal wiring. When I 
moved to W6 in 2006, I had the outbuilding that would become my shack 
and consulting office wired with EMT before I moved in.

Several other points here. First, RFI is generally NOT conducted on 
wiring from one piece of equipment to another, it is radiated by wiring 
from one piece of equipment to another. And it is often present on, and 
radiated by, the equipment ground conductor (the green wire). Properly 
installed conduit (continuous and bonded at every junction and at both 
ends) provides shielding, and prevents radiation.

Second, when I operated in Chicago, my noise level was fairly high, with 
contributions from my own home, my tenant who lived below me, the homes 
that surrounded mine, Newark's corporate office building at the end of 
my block, whatever was on power lines, and trains on the Northwestern 
track across the street. With that noise level, usually in the range of 
S6 to S8, it would be pretty hard to notice yet another noise source 50 
ft  from my antennas.

Thanks for that, Jim.

We are actually 38 miles due West of the Willis (Sears) tower in Central
Kane County.  There is virtually no industrial noise source nearby, but we
do occasionally get interference from medical apparatus.

With my 360 ft. EDZ (cut for 3.5 MHz) strung E-W at about 30 feet, I
normally have a background noise level in the S1 - S2 level, depending on
band and time of day.  I have a backup antenna in the attic (modified G5RV)
that does not fare quite as well, but is still useable.

Approximately 10 mi SW of us is a different sort of problem.  A commercial
shortwave station has been built and is operating on an experimental basis.
Their plan is to transmit market data over the pole to High Speed Traders in
Europe (milliseconds faster than cable).  They are currently licensed on
frequencies on both sides of our 40 meter band, and between our 30 and 20
meter bands.  They are using a 25 KW transmitter into an 18 db gain curtain,
with an EIRP of 808 KW.  We are located on the edge of their 38? beamwidth.
To date I have only seen them in the region just below 40 meters.  To say
they are noticeable would be an understatement.

There are quite a number of similar stations across the country, so I'm sure
others in the group have encountered them as well.

Having lived in Chicago for 42 years and maintained an engineering 
consulting practice there for 30 years, and as a former member of IBEW 
134, I'm well aware of the conduit requirement. :) Indeed, I had a lot 
of conduit installed in the 2-flat I bought on the North Side in 1986. 
Which is also why I added the phrase "the nature of electrical wiring in 
your home also matters." The large sound systems I designed and 
specified used miles of conduit for both power and signal wiring. When I 
moved to W6 in 2006, I had the outbuilding that would become my shack 
and consulting office wired with EMT before I moved in.

Several other points here. First, RFI is generally NOT conducted on 
wiring from one piece of equipment to another, it is radiated by wiring 
from one piece of equipment to another. And it is often present on, and 
radiated by, the equipment ground conductor (the green wire). Properly 
installed conduit (continuous and bonded at every junction and at both 
ends) provides shielding, and prevents radiation.

Second, when I operated in Chicago, my noise level was fairly high, with 
contributions from my own home, my tenant who lived below me, the homes 
that surrounded mine, Newark's corporate office building at the end of 
my block, whatever was on power lines, and trains on the Northwestern 
track across the street. With that noise level, usually in the range of 
S6 to S8, it would be pretty hard to notice yet another noise source 50 
ft  from my antennas.

Is the sub receiver for the K3S still available?  I cannot find it on the Elecraft website. Does anyone have one they would be willing to part with?

This is a great example a situation that demands a rig as good as a K3S! 
And probably the highest cost version of a K4.

Thanks for the spot, I was elsewhere on the bands and hadn't paid 
attention to 20M (I'm prepping for the VP8PJ team tomorrow).

Logged in under 2 minutes from the listening start; Yay Elecraft (K3, 
P3, KAT500 and KPA500) with some help from SteppIR (DB36/80 at 60').

Another band slot filled, life is good.

I thought the distance was far enough to eliminate RFI from household appliances, plasma TVs, etc. Also, the RFI is 24x7 so if it were caused by my neighbors? plasma TVs, there shouldn?t be any RFI at, say, 3AM in the morning. There are no electric fences in our area. I do have a UPS. I eliminated that as the source also.

Norman;

Elecraft has 200Hz, 250Hz, 400Hz and 500Hz filters. You can order them at the web site at the URL: https://elecraft.com/pages/k-line-transceiver-k3-k3s <https://elecraft.com/pages/k-line-transceiver-k3-k3s>
or call the main number at 831-763-4211 Monday through Friday to order. The order folks do not usually monitor this list, so it is best to contact them using the ways I mentioned.
Glad you are enjoying your K3!

73!
Jack, W6FB

I?ve never found the K3 NR very useful. But this morning, I was trying to hear VP8PJ on CW through a humongous wideband radar (or something) signal that was running over S9. The IF NB didn?t do anything against it, and the DSP NB just helped a little. I found that opening up the bandwidth to about 2.2 kHz and setting the NR to F1-3 knocked the radar down enough that I could copy him!
Unfortunately, it didn?t make him able to hear me over the loud US pileup, but I was surprised that the NR was so effective in this situation.

Eric and I are putting together a second SSB Elecraft net at 1845Z each
Sunday to follow the 20 meter net.  We will meet on 7.282.

As the propagation cycle changes, some areas were unable to participate on
20 meters.   The 20 meter net will continue as always at 1800Z.

Alternate net controls will be welcome to assist with this new effort.

Dear Members of the Elecraft SSB net and others who would like to join the net. The net meets on Sundays at 18:00 Z on a frequency of 14.303.5. Also, when Daylight savings time occurs, this will mean that the net will be one hour later if your location changes time. 

I would also like to mention that we are going to try a net on 40 meters starting next Sunday at 18:45 Z. It will be hosted by Steve WM6P who is located in Georgia. We would like to try 7.282 this coming Sunday. We may have to adjust the frequency depending on occupancy of this frequency. This is experimental at this time and we will see how it works out. I will be out of town and am not able to do the 20m net this next Sunday Feb 29th but we will have stations that can log you into the net. 

Also, I am experimenting with using Excel to log the stations and post to the reflector. I have not found a way to copy and past from Excel to the email that I use without it messing up the formatting or bouncing back as too large of a file. I am going to get some help with this in a couple of weeks. Please bear with me until I figure out how to work with this.

I just noticed that I listed the next SSB net as Feb 29th which is Saturday. It should be Sunday March 1.

Hello all:

I am wondering if this new model for Keurig has an SCR chopper to regulate temp in the heater coils?  Something changed...if I had one, I would take it into the lab to figure outn what went wrong.  Have full FCC EMI test capability--could find out if they are failing in a snap!  But, don't have one...sigh....

Is there a way to limit the audio output on the K3s to prevent sudden loud
signals from causing hearing damage? This happens in CW contest operation
and I've adjusted the AGC to minimal threshold and slope without any
significant effect. Are there any other adjustments in the unit itself? Has
anyone used an external device between the K3s and headphones to accomplish
this? If so, what device was helpful?

Thank you very much Keith and Don. Until today I haven?t had time to review
the possible failures.
I have checked and the D37 is failing so I am going to replace both D36 and
D37, what kind of diodes should I buy to replace them?
I have also checked the rest of possible and failures and everything seems
ok.

After about 100k QSO this is second fault, firts changed the pin in the back
panel about the 12 V error problem.

K3, great rig.

Asunto: Re: [Elecraft] K3 always 100 W

It could be D36 & 37 on the RF board. Earlier ones (1st few thousand) 
had weak components. But any of them can fail and usually there is 
runaway power out.
If that is not it, look for burned components under the KANT3 board 
around T4 or on the underside near D36 & 37 look for burnt traces.
If it is older than about #5500, it could be front panel tin pin 
oxidation, replaced them with gold.

I use Excel a lot!  But, I would never consider using it as any kind of
logger.

A very popular on-line program for net logging is NetLogger:

https://www.netlogger.org/

I recommend you check it out.  Several groups I frequent use it.  One cool
feature is it's on-line so one net session can have multiple users.

Scott, N3FJP, of Amateur Contact Logger fame, has a net logger:

http://www.n3fjp.com/otherprograms.html

That may suit your purposes better, especially if you don't want the on-line
capability of NetLogger.

Jerry

For #1 there are a couple of things a) in menu set one of the function 
buttons to "knob tap" and "knob hold" the select knob takes more 
pressure so using one of the function buttons is much less force. b) I 
have my K3s and P3 mounted to a single board, I put the bails down and 
then built a couple of simple clamps to clamp the bails to the board, 
makes the K3s/P3 combo a single unit not only keeps the P3 fixed but 
also simplifies cabling so they act as one unit when needing to move 
around. Kinda like having a large K4 :)

#2 go into the menu and turn the Noise Blanker on "NB En", you may have 
to experiment with the NB Level (I set mine on 5) depending on your own 
conditions.

Having lived in Chicago for 42 years and maintained an engineering 
consulting practice there for 30 years, and as a former member of IBEW 
134, I'm well aware of the conduit requirement. :) Indeed, I had a lot 
of conduit installed in the 2-flat I bought on the North Side in 1986. 
Which is also why I added the phrase "the nature of electrical wiring in 
your home also matters." The large sound systems I designed and 
specified used miles of conduit for both power and signal wiring. When I 
moved to W6 in 2006, I had the outbuilding that would become my shack 
and consulting office wired with EMT before I moved in.

Several other points here. First, RFI is generally NOT conducted on 
wiring from one piece of equipment to another, it is radiated by wiring 
from one piece of equipment to another. And it is often present on, and 
radiated by, the equipment ground conductor (the green wire). Properly 
installed conduit (continuous and bonded at every junction and at both 
ends) provides shielding, and prevents radiation.

Second, when I operated in Chicago, my noise level was fairly high, with 
contributions from my own home, my tenant who lived below me, the homes 
that surrounded mine, Newark's corporate office building at the end of 
my block, whatever was on power lines, and trains on the Northwestern 
track across the street. With that noise level, usually in the range of 
S6 to S8, it would be pretty hard to notice yet another noise source 50 
ft  from my antennas.

Thanks for that, Jim.

We are actually 38 miles due West of the Willis (Sears) tower in Central
Kane County.  There is virtually no industrial noise source nearby, but we
do occasionally get interference from medical apparatus.

With my 360 ft. EDZ (cut for 3.5 MHz) strung E-W at about 30 feet, I
normally have a background noise level in the S1 - S2 level, depending on
band and time of day.  I have a backup antenna in the attic (modified G5RV)
that does not fare quite as well, but is still useable.

Approximately 10 mi SW of us is a different sort of problem.  A commercial
shortwave station has been built and is operating on an experimental basis.
Their plan is to transmit market data over the pole to High Speed Traders in
Europe (milliseconds faster than cable).  They are currently licensed on
frequencies on both sides of our 40 meter band, and between our 30 and 20
meter bands.  They are using a 25 KW transmitter into an 18 db gain curtain,
with an EIRP of 808 KW.  We are located on the edge of their 38? beamwidth.
To date I have only seen them in the region just below 40 meters.  To say
they are noticeable would be an understatement.

There are quite a number of similar stations across the country, so I'm sure
others in the group have encountered them as well.

Is the sub receiver for the K3S still available?  I cannot find it on the Elecraft website. Does anyone have one they would be willing to part with?

This is a great example a situation that demands a rig as good as a K3S! 
And probably the highest cost version of a K4.

Thanks for the spot, I was elsewhere on the bands and hadn't paid 
attention to 20M (I'm prepping for the VP8PJ team tomorrow).

Logged in under 2 minutes from the listening start; Yay Elecraft (K3, 
P3, KAT500 and KPA500) with some help from SteppIR (DB36/80 at 60').

Another band slot filled, life is good.

I thought the distance was far enough to eliminate RFI from household appliances, plasma TVs, etc. Also, the RFI is 24x7 so if it were caused by my neighbors? plasma TVs, there shouldn?t be any RFI at, say, 3AM in the morning. There are no electric fences in our area. I do have a UPS. I eliminated that as the source also.

The thing I am wondering about is I am not hearing any CW signals on 20m, 40m or 80m.  I am just wondering if there is something I have set wrong.  I am also wondering if the RF Gain is set properly.  I know this question is a little vague but I am in the last stages of getting this remote setup working well.   Any suggestions would be greatly appreciated.  Thanks in advance.

Good Evening,

 ?? Twenty meters was very noisy with deep QSB.? Forty meters was much 
quieter with less QSB.? 0000z is about two hours before local sunset.? 
The band seems to work pretty well about then.


 ? On 14050.6 kHz at 2200z:

W0CZ - Ken - ND

K4JPN - Steve - GA

K6XK - Roy - IA


 ? On 7047.5 kHz at 0000z:

KL7CW - Rick - AK

K6PJV - Dale - CA

WM5F - Dwight - ID

K0DTJ - Brian - CA

W8OV - Dave - TX

NB5Q - Thomas - NM

KG7V - Marv - WA

W0CZ - Ken - ND


Winter is still in most peoples' forecast.? During the both nets I was 
getting snow and then sunshine.? The snow may have been causing the 
noise.? It was windy but too moist for static buildup.? In New Mexico my 
antenna could bite during a dust storm.? I learned to put the plugs into 
a quart jar until the storm passed.

 ?? Until next week 73,

 ?????? Kevin.? KD5ONS

Vic,

The NR algorithm always works better with a wider bandwidth.  It is simply building a  not-too-narrow filter around what it perceives to be the signal.  

Glad you found it helpful!

This is a test to determine if pasting from Excel will provide a readable
format.  I created this message using the "Post New Message" capability at
the Elecraft Nabble page.  I copied from an Excel worksheet I created this
morning by copying and pasting from an RBN result.  Per Nabble's
instructions, I checked the "Message is in HTML Format" box.  If it works,
this could be useful for the proposed Elecraft Net logged in Excel, or
perhaps other programs.73, Bill, K8TEde	dx	freq	cq/dx	snr	speed	timeEA5WU

Subject: [Elecraft] kx3/wsjtx, multiple notches?
Message-ID: <CADkB6UppgqGoF0=5vR14+=sV4A1Acvg6XD6n-2L2ai6=6EMABA@mail.gmail.com>

Hello,

Between the kxpa100 and getting a fan dipole just above roofline, I'm
finally able to make ft8 contacts fairly consistently in North America
when my local broadband noise source isn't operating.

There are times though when one of a couple adjacent stations a mile
or two from me either swing their beam over my dipole, or crank the
knob, and desense my kx3 pretty solidly.

I'm slowly learning how to tune the skirts and wield the notch, so can
sometimes work the one edge of the ft8 range, but there are also times
both of them are active at the same time, and trying to grab a 400kc
slice in between them to work hasn't panned out so far.

Is there a way, either in-radio, or with wsjtx, to do *two*
controllable notch filters, so the world doesn't disappear into the
shadow of +18s?

Thanks,

Scott

Instead of a notch, I?d try low-cut and high-cut to narrow in on the signal.

I have a K3S with a P3 panadapter and Microbit Remote setup with a K3 Mini that needs a new home.  Having to move into a smaller shack area. I am open to trading for Elecraft equipment.  Namely a 100 watt amp for my KX3, as a partially trade.  I would like to get $3000 for everything.  I can send pictures and full specs to interested people.  Thanks for the bandwidth.

I've got big antennas and am surrounded by big signals when I work FT8, 
but I get by just fine.  Those strong signals are causing AGC in the rig 
to reduce RF gain. What we need to do is drive the computer audio system 
harder from the radio so that weaker signals are still within range of 
the A/D converter in the computer's sound card. The fundamental settings:

1) Full RX bandwidth, let WSJT-X separate the signsls
2) Reduce RF gain (or use ATTEN) to prevent overload
3) Set audio level feeding the computer so that, when those strong 
signals are present, the green bar on the left reads about 75-80 dB but 
doesn't turn red (which indicates digital clip).

Yes, I know that #3 is not what the instructions say. But I have a LOT 
of weak signal QSOs on 160M and 6M because set up that way.

Note that K1JT strongly advises to set wide bandwidth and let WSJT-X do 
the filtering in the digital domain. All it takes to make that work is 
to use the audio drive the way I've described.

Think about it this way. The A/D in the sound card is good for about 90 
dB of dynamic range. The green bar tells us how far the signal level is 
from the BOTTOM of that range. Let's say that a strong signal is 50 dB 
over S9, and it takes over the AGC in your KX3. If the audio drive TO 
the computer sets the green bar to 30 dB, it would take a 20 dB over S9 
signal to be within range of the A/D.

But if we set the green bar to 80 dB, S9 is still 30 dB above the bottom 
of the A/D, and at 6 dB per S-unit, we can decode signals down to S4 (or 
to S4 if you call an S-unit 5 dB).

Message-ID: <82aeb422-f8f4-04ad-3ed3-ffa741bd9d1e@bell.net>

I bought a used KX3 recently and want to clean the front panel, knobs 
and bezel.

Is it safe to remove the 5 screws holding the bezel or will the display 
get dislodged?

You can download the Kit Assembly Manual from the Elecraft website. It will provide a lot of good info on how the radio goes together.

Message-ID: <202002250054.01P0s2jW013575@mail46c28.carrierzone.com>

First off all the e-mail in the digest I received at 8:27am on 
Monday, Feb. 24 were posted on Saturday, Feb.22.  Is it normal for 
the digest to wait 48-hours before posting.  My email is set for 
auto-checking every 30-minutes.

Kevin's CW Net announcement was only 24-hours late by the time I read it.

Not to the topic 80 & 40m SSB Nets:

I tuned in 14.303.5 Sunday at 1800 utc (9am AKST) and band was dead - 
nada - no WWV on 15-MHz; not even digital stuff on 14.070.  So 
obviously did not hear the 20m net.  Made me wonder if triband yagi was broke?

Local Alaskan hams have been saying 80m is good at mid-day and not at 
night!  Very different than what I used to know.  Used to be 40m 
daytime/80m nighttime prop.

So maybe 40m might have some propagation > 800 miles???  Seattle is 
only 1400 miles away.

I only have a inverted-V and 100w for 40m but may listen March 1st.

Howdy Ed,

 ?? Rick, KL7CW was my first check in on the 40 meter net yesterday.? I 
live well south of Seattle.? At 0000z the band was open to AK, ND, TX, 
NM, ID, WA, and CA.? 20 m at 2200z was broken.? Lots of noise with not 
many signals.? I think 40 meters will work well until the time change.? 
I did hear a few folks talking about 160 meters opening before sunset so 
the bands are not what one would think.

 ?? GL,

 ????? Kevin.? KD5ONS

Sorry, was this just about a way to display what was logged, in which case PDF would be good, or was it about a way to provide a plain text version of what was logged?

Frank's request prompted me to look through a box labeled "Elecraft
Cables".  I found two, brand new and still in plastic bags, KXUSB cables.
I don't really know how I came to have those. Unfortunately, there were no
KXSER cables.  But if anyone wants one of the others, I will put a very
reasonable price on them.  Or, if anyone knows why I should have them, let
me know  :-).  I have both the K3s/KPA500/KAT500 and KX3/KXPA100 stations
operating and don't seem to need them.

73,

Dave, K4TO

Message-ID: <0a8601d5ebea$e2654560$a72fd020$@LNAINC.com>

I have KPA500 s/n 3835 which I purchased along with a KAT500, factory
assembled, last Summer.

 

It soon died and was subsequently returned to Elecraft at the beginning of
August for service, and several parts were replaced.  One part was missing.

 

The unit was received back from Elecraft at the end of August and has worked
flawlessly since that time.  They extended the warranty to cover the initial
defects (thank you, Elecraft!).

 

Today, after operating a few hours, I stepped out of the shack for a couple
hours and returned to find the unit was shut off.  Everything else in the
shack was still on and operating (computers, exciter rig, etc.).  It was
impossible to power on, so I removed the fuse block and checked.  Both fuses
check OK with DMM (I am operating on 115 VAC so fuses are 12a).  There is
power thru the power cable.

 

I can't access any fault information since I cannot power it up.  I don't
seem to have a schematic nor can I find one online to check for other fuses,
etc.  (Anybody have one, or a link?)

 

Suggestions?  If possible I would like to avoid the lengthy shipping /
service delay and $100+ cost of UPS to return it yet again.  Of course I am
hoping it is something that can be field serviced.

 

Elecraft Service has been notified, but it is still early in 6-land.

 

Thanks!

Unfortunately, it is very hard for computers to extract the information in a PDF. The text can be pulled out, but the columns and other data organization are lost. I?ve worked on search engines for years, and parsing PDF is a mess. Turning a PDF back into structured text is like turning hamburger back into a cow.

If you expect to use the data for anything in the future, save it in a data format. CSV is good, XML (ADIF) is good, JSON can be good, whatever.

Extracting a log from a PDF would likely require reading the document and typing in the data. If you want a visual record that cannot be changed, PDF is a good choice.

If you don't know whether you worked them, you didn't.

Subject: [Elecraft] S6 noise floor?
Message-ID: <015a01d5eca6$ade59c10$09b0d430$@carolinaheli.com>

Aside from installing ferrite on all cables (not sure why this isn't
integrated somehow if it's that large of an issue) would having the shack
walls lined with a grounded screen help reduce/eliminate radio noise? 

Is the cost/effort worth it?

My wife and I are planning to build a house in a few years and I'm planning
out my station.

Based on the noise issues I have and have researched it sounds like I need a
shielded room where all cables in/out are wrapped in ferrite and power is
routed through a 1:1 transformer OR true sine wave UPS. 

Then I still have to deal with computer equipment noise and anything else to
get a clean signal where the ground noise is low.

Hi Jerry

Maybe.  You will have to do every piece of copper cable since everyone one
of these have the ability to be an antenna.  Any switching power supply in
your shack would also require choking.

I just spent an entire day on Saturday looking for noise up into VHF.  It
was the wall wart for an outside web cam.

I've invested a lot in my hobby.  A few hundred dollars on chokes have made
it more enjoyable.

Wow,  DXing is so different than contesting where there is a penalty  
for logging a bad QSO.

What KPA1500 setup advice did K6KR give you that was so helpful?

For this to work, you would have to also put your antenna inside this  
RF proof room but then you might not work many stations.

You may want to consider exporting excel to CSV then opening in notepad,
copy/paste from that.
It's more readable/useable in a text based environment that doesn't support
HTML cells. 
Just a thought.

Hello,

Between the kxpa100 and getting a fan dipole just above roofline, I'm
finally able to make ft8 contacts fairly consistently in North America when
my local broadband noise source isn't operating.

There are times though when one of a couple adjacent stations a mile or two
from me either swing their beam over my dipole, or crank the knob, and
desense my kx3 pretty solidly.

I'm slowly learning how to tune the skirts and wield the notch, so can
sometimes work the one edge of the ft8 range, but there are also times both
of them are active at the same time, and trying to grab a 400kc slice in
between them to work hasn't panned out so far.

Is there a way, either in-radio, or with wsjtx, to do *two* controllable
notch filters, so the world doesn't disappear into the shadow of +18s?

Thanks,

Scott

Instead of a notch, I?d try low-cut and high-cut to narrow in on the signal.

I have a K3S with a P3 panadapter and Microbit Remote setup with a K3 Mini
that needs a new home.  Having to move into a smaller shack area. I am open
to trading for Elecraft equipment.  Namely a 100 watt amp for my KX3, as a
partially trade.  I would like to get $3000 for everything.  I can send
pictures and full specs to interested people.  Thanks for the bandwidth.

I've got big antennas and am surrounded by big signals when I work FT8, 
but I get by just fine.  Those strong signals are causing AGC in the rig 
to reduce RF gain. What we need to do is drive the computer audio system 
harder from the radio so that weaker signals are still within range of 
the A/D converter in the computer's sound card. The fundamental settings:

1) Full RX bandwidth, let WSJT-X separate the signsls
2) Reduce RF gain (or use ATTEN) to prevent overload
3) Set audio level feeding the computer so that, when those strong 
signals are present, the green bar on the left reads about 75-80 dB but 
doesn't turn red (which indicates digital clip).

Yes, I know that #3 is not what the instructions say. But I have a LOT 
of weak signal QSOs on 160M and 6M because set up that way.

Note that K1JT strongly advises to set wide bandwidth and let WSJT-X do 
the filtering in the digital domain. All it takes to make that work is 
to use the audio drive the way I've described.

Think about it this way. The A/D in the sound card is good for about 90 
dB of dynamic range. The green bar tells us how far the signal level is 
from the BOTTOM of that range. Let's say that a strong signal is 50 dB 
over S9, and it takes over the AGC in your KX3. If the audio drive TO 
the computer sets the green bar to 30 dB, it would take a 20 dB over S9 
signal to be within range of the A/D.

But if we set the green bar to 80 dB, S9 is still 30 dB above the bottom 
of the A/D, and at 6 dB per S-unit, we can decode signals down to S4 (or 
to S4 if you call an S-unit 5 dB).

I use Excel to log two different nets, and routinely export the logs as PDF

It works very well.

You can download the Kit Assembly Manual from the Elecraft website. It will
provide a lot of good info on how the radio goes together.

First off all the e-mail in the digest I received at 8:27am on 
Monday, Feb. 24 were posted on Saturday, Feb.22.  Is it normal for 
the digest to wait 48-hours before posting.  My email is set for 
auto-checking every 30-minutes.

Kevin's CW Net announcement was only 24-hours late by the time I read it.

Not to the topic 80 & 40m SSB Nets:

I tuned in 14.303.5 Sunday at 1800 utc (9am AKST) and band was dead - 
nada - no WWV on 15-MHz; not even digital stuff on 14.070.  So 
obviously did not hear the 20m net.  Made me wonder if triband yagi was
broke?

Local Alaskan hams have been saying 80m is good at mid-day and not at 
night!  Very different than what I used to know.  Used to be 40m 
daytime/80m nighttime prop.

So maybe 40m might have some propagation > 800 miles???  Seattle is 
only 1400 miles away.

I only have a inverted-V and 100w for 40m but may listen March 1st.

Howdy Ed,

 ?? Rick, KL7CW was my first check in on the 40 meter net yesterday.? I 
live well south of Seattle.? At 0000z the band was open to AK, ND, TX, 
NM, ID, WA, and CA.? 20 m at 2200z was broken.? Lots of noise with not 
many signals.? I think 40 meters will work well until the time change.? 
I did hear a few folks talking about 160 meters opening before sunset so 
the bands are not what one would think.

 ?? GL,

 ????? Kevin.? KD5ONS

Sorry, was this just about a way to display what was logged, in which case
PDF would be good, or was it about a way to provide a plain text version of
what was logged?

Frank's request prompted me to look through a box labeled "Elecraft
Cables".  I found two, brand new and still in plastic bags, KXUSB cables.
I don't really know how I came to have those. Unfortunately, there were no
KXSER cables.  But if anyone wants one of the others, I will put a very
reasonable price on them.  Or, if anyone knows why I should have them, let
me know  :-).  I have both the K3s/KPA500/KAT500 and KX3/KXPA100 stations
operating and don't seem to need them.

73,

Dave, K4TO

Content-Type: text/plain;	charset="us-ascii"

I have KPA500 s/n 3835 which I purchased along with a KAT500, factory
assembled, last Summer.

 

It soon died and was subsequently returned to Elecraft at the beginning of
August for service, and several parts were replaced.  One part was missing.

 

The unit was received back from Elecraft at the end of August and has worked
flawlessly since that time.  They extended the warranty to cover the initial
defects (thank you, Elecraft!).

 

Today, after operating a few hours, I stepped out of the shack for a couple
hours and returned to find the unit was shut off.  Everything else in the
shack was still on and operating (computers, exciter rig, etc.).  It was
impossible to power on, so I removed the fuse block and checked.  Both fuses
check OK with DMM (I am operating on 115 VAC so fuses are 12a).  There is
power thru the power cable.

 

I can't access any fault information since I cannot power it up.  I don't
seem to have a schematic nor can I find one online to check for other fuses,
etc.  (Anybody have one, or a link?)

 

Suggestions?  If possible I would like to avoid the lengthy shipping /
service delay and $100+ cost of UPS to return it yet again.  Of course I am
hoping it is something that can be field serviced.

 

Elecraft Service has been notified, but it is still early in 6-land.

 

Thanks!

Unfortunately, it is very hard for computers to extract the information in a
PDF. The text can be pulled out, but the columns and other data organization
are lost. I?ve worked on search engines for years, and parsing PDF is a
mess. Turning a PDF back into structured text is like turning hamburger back
into a cow.

If you expect to use the data for anything in the future, save it in a data
format. CSV is good, XML (ADIF) is good, JSON can be good, whatever.

Extracting a log from a PDF would likely require reading the document and
typing in the data. If you want a visual record that cannot be changed, PDF
is a good choice.

I'm not entirely sure I've worked VP8PJ yet--they are in the noise on my
modest antennas--but if I did, it was some KPA1500 setup advice a while back
from?Dick Dievendorff, K6KR,? another Elecraft guy who doesn't get enough
praise.? Thanks, Dick.? My K3/KPA1500 is a joy to use on CW pileups.

If you don't know whether you worked them, you didn't.

You may want to consider exporting excel to CSV then opening in notepad,
copy/paste from that.
It's more readable/useable in a text based environment that doesn't support
HTML cells. 
Just a thought.

This is a test to determine if pasting from Excel will provide a readable
format.  I created this message using the "Post New Message" capability at
the Elecraft Nabble page.  I copied from an Excel worksheet I created this
morning by copying and pasting from an RBN result.  Per Nabble's
instructions, I checked the "Message is in HTML Format" box.  If it works,
this could be useful for the proposed Elecraft Net logged in Excel, or
perhaps other programs.73, Bill, K8TEde	dx	freq	cq/dx	snr

Message-ID:

Content-Type: text/plain; charset="UTF-8"

Hello,

Between the kxpa100 and getting a fan dipole just above roofline, I'm
finally able to make ft8 contacts fairly consistently in North America when
my local broadband noise source isn't operating.

There are times though when one of a couple adjacent stations a mile or two
from me either swing their beam over my dipole, or crank the knob, and
desense my kx3 pretty solidly.

I'm slowly learning how to tune the skirts and wield the notch, so can
sometimes work the one edge of the ft8 range, but there are also times both
of them are active at the same time, and trying to grab a 400kc slice in
between them to work hasn't panned out so far.

Is there a way, either in-radio, or with wsjtx, to do *two* controllable
notch filters, so the world doesn't disappear into the shadow of +18s?

Thanks,

Scott

Instead of a notch, I?d try low-cut and high-cut to narrow in on the signal.

I have a K3S with a P3 panadapter and Microbit Remote setup with a K3 Mini
that needs a new home.  Having to move into a smaller shack area. I am open
to trading for Elecraft equipment.  Namely a 100 watt amp for my KX3, as a
partially trade.  I would like to get $3000 for everything.  I can send
pictures and full specs to interested people.  Thanks for the bandwidth.

I've got big antennas and am surrounded by big signals when I work FT8, 
but I get by just fine.  Those strong signals are causing AGC in the rig 
to reduce RF gain. What we need to do is drive the computer audio system 
harder from the radio so that weaker signals are still within range of 
the A/D converter in the computer's sound card. The fundamental settings:

1) Full RX bandwidth, let WSJT-X separate the signsls
2) Reduce RF gain (or use ATTEN) to prevent overload
3) Set audio level feeding the computer so that, when those strong 
signals are present, the green bar on the left reads about 75-80 dB but 
doesn't turn red (which indicates digital clip).

Yes, I know that #3 is not what the instructions say. But I have a LOT 
of weak signal QSOs on 160M and 6M because set up that way.

Note that K1JT strongly advises to set wide bandwidth and let WSJT-X do 
the filtering in the digital domain. All it takes to make that work is 
to use the audio drive the way I've described.

Think about it this way. The A/D in the sound card is good for about 90 
dB of dynamic range. The green bar tells us how far the signal level is 
from the BOTTOM of that range. Let's say that a strong signal is 50 dB 
over S9, and it takes over the AGC in your KX3. If the audio drive TO 
the computer sets the green bar to 30 dB, it would take a 20 dB over S9 
signal to be within range of the A/D.

But if we set the green bar to 80 dB, S9 is still 30 dB above the bottom 
of the A/D, and at 6 dB per S-unit, we can decode signals down to S4 (or 
to S4 if you call an S-unit 5 dB).

I use Excel to log two different nets, and routinely export the logs as PDF
files.

It works very well.

You can download the Kit Assembly Manual from the Elecraft website. It will
provide a lot of good info on how the radio goes together.

First off all the e-mail in the digest I received at 8:27am on 
Monday, Feb. 24 were posted on Saturday, Feb.22.  Is it normal for 
the digest to wait 48-hours before posting.  My email is set for 
auto-checking every 30-minutes.

Kevin's CW Net announcement was only 24-hours late by the time I read it.

Not to the topic 80 & 40m SSB Nets:

I tuned in 14.303.5 Sunday at 1800 utc (9am AKST) and band was dead - 
nada - no WWV on 15-MHz; not even digital stuff on 14.070.  So 
obviously did not hear the 20m net.  Made me wonder if triband yagi was
broke?

Local Alaskan hams have been saying 80m is good at mid-day and not at 
night!  Very different than what I used to know.  Used to be 40m 
daytime/80m nighttime prop.

So maybe 40m might have some propagation > 800 miles???  Seattle is 
only 1400 miles away.

I only have a inverted-V and 100w for 40m but may listen March 1st.

Howdy Ed,

 ?? Rick, KL7CW was my first check in on the 40 meter net yesterday.? I 
live well south of Seattle.? At 0000z the band was open to AK, ND, TX, 
NM, ID, WA, and CA.? 20 m at 2200z was broken.? Lots of noise with not 
many signals.? I think 40 meters will work well until the time change.? 
I did hear a few folks talking about 160 meters opening before sunset so 
the bands are not what one would think.

 ?? GL,

 ????? Kevin.? KD5ONS

Frank's request prompted me to look through a box labeled "Elecraft
Cables".  I found two, brand new and still in plastic bags, KXUSB cables.
I don't really know how I came to have those. Unfortunately, there were no
KXSER cables.  But if anyone wants one of the others, I will put a very
reasonable price on them.  Or, if anyone knows why I should have them, let
me know  :-).  I have both the K3s/KPA500/KAT500 and KX3/KXPA100 stations
operating and don't seem to need them.

73,

Dave, K4TO

Content-Type: text/plain;	charset="us-ascii"

I have KPA500 s/n 3835 which I purchased along with a KAT500, factory
assembled, last Summer.

 

It soon died and was subsequently returned to Elecraft at the beginning of
August for service, and several parts were replaced.  One part was missing.

 

The unit was received back from Elecraft at the end of August and has worked
flawlessly since that time.  They extended the warranty to cover the initial
defects (thank you, Elecraft!).

 

Today, after operating a few hours, I stepped out of the shack for a couple
hours and returned to find the unit was shut off.  Everything else in the
shack was still on and operating (computers, exciter rig, etc.).  It was
impossible to power on, so I removed the fuse block and checked.  Both fuses
check OK with DMM (I am operating on 115 VAC so fuses are 12a).  There is
power thru the power cable.

 

I can't access any fault information since I cannot power it up.  I don't
seem to have a schematic nor can I find one online to check for other fuses,
etc.  (Anybody have one, or a link?)

 

Suggestions?  If possible I would like to avoid the lengthy shipping /
service delay and $100+ cost of UPS to return it yet again.  Of course I am
hoping it is something that can be field serviced.

 

Elecraft Service has been notified, but it is still early in 6-land.

 

Thanks!

Unfortunately, it is very hard for computers to extract the information in a
PDF. The text can be pulled out, but the columns and other data organization
are lost. I?ve worked on search engines for years, and parsing PDF is a
mess. Turning a PDF back into structured text is like turning hamburger back
into a cow.

If you expect to use the data for anything in the future, save it in a data
format. CSV is good, XML (ADIF) is good, JSON can be good, whatever.

Extracting a log from a PDF would likely require reading the document and
typing in the data. If you want a visual record that cannot be changed, PDF
is a good choice.

If you don't know whether you worked them, you didn't.

Hi,
Start with Jim's, (K9YC), pages, at:

http://www.k9yc.com/publish.htm

Read most of them, (the titles will direct you), then you will have a 
far better idea of how to reduce RFI without a shielded room...

After that look at:

https://www.nk7z.net/rfi-now-house-cleaning/

I cleaned up my shack, with very good results...

They updated the online log yesterday. 

I got them on 4 bands so far. New country and all new band slots for me. 

I heard ?someone? on 7009.88 CW last night that was spotted as VP8PJ but it was AH0U.

VP8PJ is active for another week. People should check the online log to ensure you are in it. 

BTW my KPA1500 has Ben working flawlessly since it went back for updates.

Yes, but .pdf preserves the author's content and formatting and is 
viewable by anyone using Adobe Reader (free).
LibreOffice will reliably export a .doc or .xml file as a .pdf document. 
  I don't know about Microsoft Office since I don't use it.

In my day job, I do Electronic Data Interchange (EDI) work.  Most of it
involves PDFs of the standards that the trading partner uses,  and more
often than I would like, I see the PDFs containing sample data (which in an
ideal world are actual text data, because we have to send them through a
process called "translation" that takes ASCII and little else as input.)

Adobe Reader - at least the version I have - has a menu option under File
which is "Save as Other..."  and the only option is Text.   And it does!
It saves the PDF as a text document.   What a Godsend.   I do not know when
this started, but there's a special place in heaven for the person who came
up with this function to Adobe Reader.

I would say it differently. I would say PDF is where text goes to be read. I decline to download any text file that?s not PDF. Too risky. It's amazing to me how many people will send out a file in a proprietary format like Microsoft Word and expect all the recipients to be able to read it.

If you do not have Microsoft Word, then you should download and install 
LibreOffice.  It is a full Office suite that is quite similar to 
Microsoft Office.  And it is free to use.  It will read any file 
produced by MS Office, and it also exports to .pdf format.

In addition to Libre Office, there still is Open Office (now supported by The Apache Software Foundation).It appears that at some point the original Open Office morphed into Libre Office... and AFAIK, all the generated files from each application are compatible with each other, and will permit you to export a new file in Word (or other MS App) format. ?

At that point, you have to hope that the original developer of that now broker app will have updated it to run on the new OS.
I had that situation with EchoMac... a compatible version of EchoLink.

I know all about the alternatives to Microsoft word. I actually have Microsoft word. The point is that PDF is the most accessible format that we all have in common. Why use some more proprietary or exotic format to transmit something that does not need the features of these programs you suggest. If I only need them to read the message, I'd rather use what I have and avoid the complexities of downloading new software. I think it is correct to say that any word processing software can create a PDF document for simple text. Why must a user be forced download a new program when a little bit of an attention to detail can create a document everyone can read?

During my employed life, I worked on classified projects for the 
military and we often worked in SCIF's [shielded rooms] to keep the 
computer emissions confined.? Double doors with phosphor bronze fingers 
on each, copper shielding in the walls, floor, and ceiling, etc.? 
Generally speaking, a test radio was pretty much silent inside on any 
frequency.

However, all of the noise I see on my P3 and hear comes in on the

hiss.? I doubt shielding your shack will be worth the cost and effort.? 
You can't beat K9YC's dissertation on chokes [

WILL have a profound effect on common mode noise.

As others have noted, ferrites will help attenuate RFI ** IF ** you own the
offending source and can choke it for radiation or choke your own wiring
against common-mode pickup. 

However, I find that RFI generators over which I have no control are the
predominant sources at my QTH after all the local offenders are quenched,
e.g. arcs on tie wires or transformer connections in the electricity
distribution wiring in my neighborhood and beyond, and RF egress from
defected coax sheaths in the cable distribution network.

Interestingly, the local power company RFI hunter told me that he works hand
in glove with the cable companies because the cable customers report TV,
internet and telephone interference that is traced to power line arc
generators making ingress to the cable network - both utilities find the
weak points in their respective systems.

Mike, K8CN

You can also just highlight the text you want in the PDF document and 
copy/paste it into another document.

The only time you can't extract text from a PDF is if the PDF was made 
from a scanned image.? (Actually, you can buy software that can read 
text from an image, but I don't know how accurate it is.)

Of course not. RFI is received by ANTENNAS, not wiring in the station. 
The things that ARE important are 1) proper bonding of all equipment in 
the station; 2) bonding of the station to all grounds in the home; 3) 
elimination of all noise sources in your home, and 4) application of 
effective ferrite chokes to those sources you can't elimnate.

Yes. That's my method. I usually work in a old versions of Word and 
Quattro Pro, then use Libre Office to generate the pdf. The thing to 
watch out for is that Libre Office can make changes in formatting, 
fonts, etc. that need to be corrected, so I always check the pdf before 
putting it on my website.

I echo the recommendation for OpenOffice.? I also own MS Office 2010 but 
OpenOffice is actually more up to date, and as you say, it's free.? As 
an example, I recently had a need to be able to use hyperbolic sine 
functions on complex numbers for some transmission line calculations.? 
Excel didn't add that capability until after 2010, while Open Office 
Calc has them.? MS Office 2010 will be the last version I ever buy, or 
"lease" now that it is cloud based.

I was surprised that I could understand some (maybe 20%) of the German

It helped that a lot of the words were ones like "Elecraft", "DX",

Hi Jerry.

The first thing to check, is if the "noise" is from your own stuff, or
outside you immediate control.

You can do that easily, by running the rig from batteries (internal or
external) and turning the house off at the main incoming switch.

If the noise level drop's significantly, then you're in with a fighting
chance of tracking down the source(s).?? Go arround unplugging/turning
off "Everything" you can find.

Note the noise level, then turn one at a time back on, and see what is
the main source.

Don't forget anything that is not on a plug-lead.

If there is no change when you turn your house off, then it's something
outside.? A screened room won't help, as of course your antennas need to
be out in the open.

You might want to take a radio and antenna /P to wherever you are
thinking of building a new house, and do a background RFI survey, before
you commit yourself..

73.

Dave G0WBX.

I am trying to run my Flex6600/ KPA500/KAT500 remotely.

Does anyone know if it is possible to hook up a PC & a Flex to a KAT500 at
the same time?

I have the KPA500/KAT500/Flex working together. I also have the KPA500
Remote S/W working on a PC. But I would like to also monitor/control the
KAT500 at the same time.

As best I can tell you can only connect a single KXUSB cable to the KAT.

Any suggestions?

Thanks,

Subject: [Elecraft] Flex6600 + KPA500 + KAT500
Message-ID: <1582778800750-0.post@n2.nabble.com>

I am trying to run my Flex6600/ KPA500/KAT500 remotely.

Does anyone know if it is possible to hook up a PC & a Flex to a KAT500 at
the same time?

I have the KPA500/KAT500/Flex working together. I also have the KPA500
Remote S/W working on a PC. But I would like to also monitor/control the
KAT500 at the same time.

As best I can tell you can only connect a single KXUSB cable to the KAT.

Any suggestions?

Thanks,
Mick

I'm not sure about how much the Flex demands the CPU, but I have the 
KAT500 Utility and the KPA Utility running while a third port manages 
the K3 (via HRD).? (A 4 port real RS-232 board in the computer, USB 
doesn't always play well in QRO environments; the 4th port manages 
keying CW and FSK while AFSK is still an option.)

These apps give me insight (SWR, power out etc) and control (standby, 
operate. switch antennas) over the transmitting and antenna elements 
(well, add PSTRotator for rotor and SteppIR control).

The key here is to make sure that it all runs on one computer successfully.

Since my station all runs on one computer at the same time, when I 
remote the computer, I remote the station (TeamViewer).? I add in Skype 
for audio (CW and phone).

So yes, it should be possible for you.? One bonus is that you're running 
your station (remotely or not) and no one has to know where you are and 
your log is accurate since it's based on the station location, not yours.

I?m running a K3 system (K3-KAT500-KPA500) and a Flex System (Flex-6700 and PGXL) remotely from my ham shack in SE Georgia.  It is certainly possible to run both ?flavors? of equipment at the same time remotely.

You apparently have the KPA500 and Flex running remotely to your satisfaction.  The question is how to configure the KAT500.  

I have my KAT500 interconnected with the K3 and KPA500 through the ?Control? 15-pin  connectors as ?normal? to feed band data to one another.    Presumably you?d have your KAT500/KPA500 connected to the Flex using BCD through the control connectors so that the Flex and Elecraft gear talk to each other.  Take a look at the Flex document, ?USB Cables Interface for the Flex-6000? that goes into detail on how to use the Flex USB interface to connect to other devices of various types (CAT, Bit, BCD, LDPA , DSTAR).  The cable I use for BCD connections with my Flex can be found at Amazon:

https://www.amazon.com/gp/product/B00HKK4SCO/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 <https://www.amazon.com/gp/product/B00HKK4SCO/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1>

You?ll need to wire the non-USB end for (which comes with breakaway PCB Board Header Connectors) for the proper connection to the 15-pin remote connector side of the KPA500/KAT500  .In my case, I originally used this cable to communicate with the Antenna Genius BCD connector.  

In summary, the serial interface of the KAT500 provides the ability to manage/control the KAT500.  You can run the KAT500 utility on a PC in the shack and remorely access it, or setup a serial-to-ethernet interface to allow remote serial connection to the KAT500 by a PC that is at your location to control it with the KAT500 utility.  The ?control  connection?  (BCD) provides the ability of the KAT500 to communicate Band Settings with other equipment (KPA500, K3, Flex, etc.).  As noted, you will need to get the appropriate cable that allows the Flex to feed/receive BCD data through a USB connection on the back of the Flex to the KAT500/KPA500.

You may also want to post a query to the Flex Community about interfacing the Flex to Elecraft gear to see what others may suggest as well.   

Hope this answers your question,

Mick, I have a KPA/KAT500 combo connected to my 6600. Both the KPA and KAT are connected to ?serial? ports (USB to serial adapters) on the shack computer that runs 24/7. None are connected to the Flex. Elecraft?s excellent remote software is running on the shack computer in Host mode. This has to be started manually, but could be auto started, I?ve just not done so. I can access my shack computer remotely to (re)start the hosting if the computer reboots for any reason. 

From the laptop, I can connect to the shack hosted software and have full control over both the KPA and the KAT. A quick bump of RF, like the Flex tune mode instantly tunes the KAT, selects an antenna based on the RF. Putting the KPA in Operate mode automatically selects the proper band on the next burst of RF. 

I use this whether on my local LAN but not in the shack, or hundreds (thousands) of miles away. I?m very pleased with the KPA/KAT functionality for the Flex. 


tnx

Another idea is to run a Raspberry Pi on the network running Node Red software.  The nice thing about Node Red is I can monitor and control equipment through any web browser and not have the bandwidth overhead of a remote desktop solution. This is key if anyone is doing this over cellular and is in poor coverage area or does not have unlimited data.

In Node Red I created ?flows? which allow me to monitor and control:
KPA1500
rotor (Via PSTRotator AZ IP server)
DLI Web Switch Pro to turn equipment and relays on and off.
Flex 6700 to monitor radio info 

You could have Node Red talk to the KPA500/KAT500 via serial connection and it should support any of the functions listed in the KPA500 programmers reference manual.

I think there is one person on the Flex Community that has written a Node Red flow for the KPA500/KAT500.

Here?s some pics of my Node Red setup. One shows it split screen on my iPad with the Flex IOS software. I only have the controls on screen for functions I wanted readily available. I am planning to add ability to retune the KPA1500 tuner as well. Right now I only use the tuner on 80 meters.

A note of caution interchanging documents.
For plain text sharing and editing documents is fine in a varietyof word processing apps. However when it becomes a table, and more so withembedded graphics then the file conversions between different word processorsis non-reciprocal.If you set up a document eg in MS Word, post it to anotherword processor. Add and remove a space to force a new save and send it backthen whilst it looks fine the two files are different.

It can be a time bomb.

We used to prepare documents, text and formulae in tables inMS Word which colleagues would edit in whatever system they had.? After a few rounds the table format wouldcrash rendering the document useless.
After some 'fun' we repeatably demonstrated the problem. Itwas not necessarily the very last format conversion that caused the problem,omitting an earlier change made 'this' change work as expected.? The faulty document looked OK but failed thenext, or next but one, change of platform.

YES!  This is the kind of stuff that can get screwed up in file 
interchange. That said, I use tables in Word to insert graphics and 
photos. They are simple tables, typically one or two rows by two 
columns, with the graphic/photo on one side and the text on the other, 
and this formatting tends to hold up OK going from Word to Libre Office 
where I generate the pdf.

There are several dozen docs on my website done this way.

No. Scanning proceeds from the VFO A frequency to the VFO B frequency, and is actually implemented only on the main receiver. This applies to the K3/K3S/KX2/KX3.

The K4 will likely have additional scanning options, e.g. scanning separately on the two receivers.

Howdy Gang.

In view of receiving my K4 sometime in the coming months (I hope?grin), I find that my KX3 system is now excess to my needs.

So, I am offering for sale the following package of equipment?all items are in excellent or better condition physically and operationally.

KX3-F			s/n 9057

KAT3
KXFL3
KXBC3 
KX32 Ultimate Headsink
KX3S Power Supply

PX3-F			s/n 0920

KXPA100-K		s/n 1620	

Nifty stands for the KX3 and PX3

KX3 and PX3 have the Gemsproducts end panels and covers.

Includes original manuals, all cables.

Will ship for $2500 CONUS.

This is the finest QRP/100W station I?ve owned in 58 years on the air?I can only hope the new K4 is as good.

Have a FB weekend and enjoy.

One key spec we haven?t heard anything about yet is the transmit bandwidth capability of the K4 on AM.  I certainly hope the design options substantially exceed the rather poor and restricted transmit bandwidth of the K3, and that there aren?t any unnecessary artificial ?political? restrictions.  It would seem that the K4, like the Flex radios for example, should be capable of providing outstanding, clean, AM transmit performance with adjustable transmit audio bandwidth to suit conditions, etc.

My P3 has started to exhibit some strange behavior since I installed the SVGA and TXMon options.  Every time I turn the VFO A the P3 acts like it is being overloaded and the display shows interference.  I have never noticed this before.  Has anyone seen this behavior before?  I am running a K3S with the P3.

Robin,

I certainly have not seen that behavior, but recommend you go over the 
P3SVGA and P3TXMON option instructions.
Are all cables fully plugged in, and are the cables dressed inside like 
what is shown in the diagrams?  You may have to devise some kind of 
'clip or support' to keep the cables in place.  If I recall, I used a 
length of wire to wrap around the cables for the P3SVGA to keep them in 
place.  I do not have the P3TXMON option installed.

73,
Don W3FPR

Howdy Gang.

In my earlier for sale listing I forgot to mention that the KXPA100 in the system has the KXAT 100W tuner built-in.

Regret the oversight.

Hi Grant,

The K4 will allow independent setting of TX bandwidth for voice and audio data modes up to something in excess of 4 kHz. SSB, ESSB, AM, and audio data will each have their own setting.

As with the K3S, it'll be up to the user to judge whether the use of wider bandwidths is acceptable under the given operating conditions. This subject will be discussed in the owner's manual.

I believe the theoretical limit is in the 5.something range, and we'll certainly test this.

I must respectfully disagree.

Often, PDF is read-only.  Sometimes you can break that, sometimes you can't.

You need a PDF reader.  I suspect we all have them, but you can't open 
it in most word processors.

Rich Text Format (.rtf) is pretty much universal, can be opened (and 
edited) by every word processor I'm aware of, and because it does not 
have a macro facility, it doesn't carry malware.

Several of us K3S users have noticed a brief intermittent popup on USB when on 80M LSB. It seems to have something to do with transmit ALC settings, but can't get rid of it.
It also happens most with higher in frequency voice syllables.
One operator switched from his KS3 to a 7300 and the USB was clean.
Any ideas?

Subject: [Elecraft] MMTTY issue
Message-ID: <mailman.641.1582943025.13233.elecraft@mailman.qth.net>

I am running to 2 K3 radios  for SO2R and having an issue with MMTTY Mark settings (running the programs with N1MM+).   On one K3, I have the MMTTY Mark setting for 2125 and in the Engine window I am receiving the signal just fine, but on the 2nd MMTTY, there is so signal on the Engine window when I set the Mark for 2125.  I have to go down to the Mark setting of 915 to receive the signal (as I go down from the Mark settings of 2125 to 915 the signal comes from the left side until centered).

My setup:

1. I am running 2 external soundcards (Xonar) and have changed them back and forth between the 2 radios and get the same problem no matter which soundcard I use.
2. Have same problem no matter which filter I use (2.7 ? 2.1 ? 400)
3. DSP off
4. Filter controls are set identical
5. Data mode on both K3 are set to 45 baud AFSK.
6. MMTTY settings are identical  in their configuration.
7. N1MM+ configured to AFSK when MMTTY are launched.

All works fine in receive and transmitting when making contacts, just have the issue with setting the Mark being different on the MMTTYs.  

Just wondering if their might be a K3 Config difference between the 2 I might be missing.

Any comments as to why I might be having to set the Mark different on MMTTY (2125 versus 915) to receive the signal to decode for the 2 K3 radios.

Thanks ? David - ND4Y

When in the Data mode you are using, press the SPOT/Pitch button (lower-left of the keypad) and hold. It should show the Mark freq. adjust to suit.

For the radio setting I use AFSK A at 45BPS setting for MMTTY. Only use 
the signle USB cable between the radio and computer. ? No other hardware 
or interface.

I don't use N1MM.

Jim

if all you're using Open/Libre Office for is creating PDFs, you may want
to look at the PDF printer driver from Software995.com.??? Its free
(with ads) but if you want to pay the $9.95, its yours for life.??? I
use it for all my work, and I create a LOT of PDFs as records of
transactions in my bookkeeping role.

I am in the process of getting a Genovation KeyPad working with the 
P3/SVGA but also want to have the keyboard available as I like to run 
RTTY and CW without the computer.? So I have a few questions:

1) Has anyone found a USB switch that would allow selectable use of a 
keyboard or the genovation with the P3/SVGA.? There are multiple USB 
switches for sharing peripherals between computers but I have found 
nothing that serves as manual USB hub equivalent.? The P3 cannot work 
with a USB hub so need something like the old RS232 switch box.? Right 
now I just plug and unplug but laziness is the mother of invention so 
looking for a simpler approach.

2) What methods are people using to load macros into the P3/SVGA.? The 
only approach I am a aware of is through manual keyboard entry which is 
error prone.? I believe that once the macros are stored in the P3/SVGA 
that they are saved with the configuration but there is no ability to 
edit the 50 macro locations.? Back on 6/11/2018 Paul had stated "...The 
next BETA release of P3/SVGA firmware will include the ability to 
export/import macros from/to the SVGA just like the PX3." but I am 
unable to find any BETA releases since that time. ? The P3 Utility is 
limited to only 16 Macros so that doesn't handle the problem. The 
capability that the PX3 has for exporting/importing/editing of macros 
would be extremely helpful.

3) Using the the P3 MENU -> SVGA menu->? SVGA Usav you can save the SVGA 
state via USB stick which creates a file "SVGASET.sav" file name.? I am 
able to open this file with a Notepad++ and see that it does contain 
macro information but I cannot find any information on the file format.? 
File contains a lot of NUL characters and appears to have 3 sections.? 
Has anyone decoded this format and knows how to safely edit?? The PX3 
Programmers Manual shows the format for the PX3 files and it appears 
that the macro section may be the same but looking for more definitive 
information.

Hi Dave,

Using the setup described at:

https://www.nk7z.net/adding-external-keypad-k3/

I have been unable to swap to a KBD from the Genovation.  I direct swap 
fails, so prior to purchasing a switch, do a manual replace to insure it 
works for you...

Macro Loading is by hand, using that God awful editor that lives in the P3.

I was thinking of writing an editor for the file the P3 generates, but 
as it is Elecraft hardware, (and I, not having the specs for it), have 
decided to not do that, so I don't break the hardware inadvertently.

I seem to remember a Macro Editor for the P3 being promised as well, but 
for the life of me, I can't find the reference to it now...

You are correct, it is a PITA to enter 48 macros by hand...

But, hacing the radio macro set available at a sngle button press has 
been a Godsend for pile up operations...  I have a macro spread sheet 
there, that has a "Split + 5", macro, so when I hear VP8PJ, I SPOT it, 
then hit the "SPLIT + 5" button, that moves the DX station to the left 
side of the P3, opens the bandwidth of the P3 up to 6 KHz., and makes 
VFO B the transmit VFO, leaving the DX station on the left side.  Makes 
it a snap to find a hole and work them.  Using that method, iot took me 
three button presses, and a few tuning adjustments to get them on 40...

I can tell you from experience, that using the Genovation, and it's 48 
macro launch buttons makes using the radio a breeze.  I had occasion to 
use a friends K3, without a Genovation, and it felt crippling...

Please let me know what you find for Macro Editors, or external 
keyboards, I'll add it to the web page on the Genovation...

73, and thanks,
Dave (NK7Z)

Both Libre Office and Open Office are free complete suites for Word 
Processing, spreadsheet, presentations, and database uses.  What is 
more, they are multi-platform.  Quite comparable to MS Office and have a 
similar look and feel.

They can be set to save in MS Office formats, but those are not the 
default file types.  I use Libre Office for all my documents and 
spreadsheets as well as exporting as .pdf files.  Don't have MS Office 
on any of my computers, except for the one my wife uses - she won't 
switch, yet!

Good Evening,

 ?? I have used one tree to heat my house this heating season from 
October through February.? It won't last through March.? I cut up a few 
piles of bark yesterday.? At two inches thick they make good kindling.? 
After I picked them up the Veerys fluffed up the newly opened area.? The 
robins came next to check for worms with their hop and listen 
technique.? Two hairy woodpeckers banged away on the fresh log 
surfaces.? When they were done they both landed on the side of tree and 
hung motionless for about twenty minutes.? I think they ate too much.

 ?? Propagation remains much the same: QSB, space noise, and weak 
signals.? That has never stopped us before.? I have hope the sun will 
become active again one day.? It might not be soon but it will happen.? 
0000z for 40 meters has been working very well. 2200z for the 20 meter 
net not so much.? However, things will change as soon as we move into 
Daylight Savings time.


Please join us tomorrow on:

14050 kHz at 2200z Sunday? (2 PM PST Sunday)
 ?7047 kHz at 0000z Monday? (4 PM PST Sunday)
