I agree with Wayne that a noise blanker is responsible for what you are 
seeing. FWIW, what these two blankers are CALLED in their setup menu 
(long push of NB) is VERY confusing. Fact is, that they are BOTH working 
in an IF, one in the first IF and the other in the second. FAR better to 
call them IF1 and IF2. NOW it becomes clear which is post-xtal filter.


How we talk about something makes it either easier or more difficult to 
understand. That's why I strongly object to use of the word "balun," 
which is used to describe almost a dozen VERY different THINGS, and 
multiple meanings of the word "ground," all of them very different from 
each other. Another is the phrase "ground loop." All three uses often 
cause people to do really dumb things to solve a problem because the 
words don't describe what is really going on!

Re: [Elecraft] [EXTERNAL] Re: K2 audio problem

[Pawlak, Daniel L]

Don,
   Thanks for the advice. I did the alignment with Spectrogram. A few of the 
filters were off, and I corrected them. However, it didn't make much difference 
in improving SSB intelligibility. I then realized that the KDSP2 might be 
introducing artifacts to the audio.  I turned the denoiser off, and the audio 
was much better, but the noise was unbearable. I was gong to play with the 
various settings, when I remembered there were many differing opinions on how 
to set them up properly, and I think the conclusion was that the factory 
settings should be used. Did I recall correctly? If that's the case, can you 
share them with me? I might have mucked them up a long time ago.

Dan,

Align the IF filters.  I have no idea what may have made them change,
unless you tried to do a Master Reset which would change the filter
settings back to factory defaults, which only work well in a few K2s.

It is best if you use an audio spectrum analyzer running on your
computer to see where the filter passband is located in the audio spectrum.

Information on how to set up Spectrogram can be found on Tom Hammond's
(N0SS, now SK) website which has been preserved at
https://urldefense.proofpoint.com/v2/url?u=http-3A__www.mmccs.com_mmarc_n0ss_k2-5Ffilters-5Fusing-5Fgram-5Fv5r17.pdf=DwICaQ=YC-d702opsuYKpiO2Bmlzg=kP1njbluGgLcMdyEofM_F-lOGeRxHPEzfZ061VLXuAc=Sf-V4Vad14JSlM60ZznWp6L217ZRrXQqyxHStbeBmgY=3poR3hBdK3n1-SXX_YitFbw26l5srWNxRxpeNqfoCwE=.

If you need a copy of Spectrogram, go to my website 
https://urldefense.proofpoint.com/v2/url?u=http-3A__www.w3fpr.com=DwICaQ=YC-d702opsuYKpiO2Bmlzg=kP1njbluGgLcMdyEofM_F-lOGeRxHPEzfZ061VLXuAc=Sf-V4Vad14JSlM60ZznWp6L217ZRrXQqyxHStbeBmgY=lXG8j1NvNQy33wPnljdeJS8T7K4Aape696X1oRpqDfY=
 and
scroll near the bottom of the opening page.  There you will find links
to Spectrogram version 5.17 and version 16.  These files are local to my
website.

If you did a Master Reset, also refer to the K2 dial Calibration article
on my website.  You will have to do a CAL PLL in addition to the filter
alignment (CAL FIL).

Advice to all - do not do a K2 Master Reset unless you first record ALL
your menu settings, including the Filter settings.  The first few pages
of the K2 A to B upgrade instructions has instructions for recording all
you menu settings.  Restore them after a Master Reset.

Re: [Elecraft] Horrible APRS QRM on 2 Meters

[Wayne Burdick]

Another thought: The K3 has two noise blankers. The hardware blanker does see a 
broad input frequency range (so it can suppress very fast-rise-time noise 
pulses), and as with similar blankers, you have to keep the NB threshold high 
enough to not cause intermod. 

Try using just the DSP blanker, which is post-crystal-filter. Or a touch of 
each. This can be very effective on disparate noise sources.

Re: [Elecraft] Horrible APRS QRM on 2 Meters

[Wayne Burdick]

Dick,

Just to make sure I understand: are you using the K3 as an IF? If so, what band 
-- 10 meters?

It makes no sense that the K3 would have difficulty with out of band signals in 
the manner you describe. It has far better dynamic range on all bands, 
including 10 meters, than the TS-590.

[Elecraft] Horrible APRS QRM on 2 Meters

[Richard Beerman]

Wonder if anyone else has encountered this on 2 Meters? I am using a 12 ele 
K1FO yagi - about q12 dB gain on 2. That enters the shack where it is connected 
to a Downeast Microwave 50 Watt transverter with about 17 dB gain on receive. 
The output of the transverter is connected to transverter input on my old K-3. 
For the longest time, I was receiving loud QRM from what I initially thought 
were power line noise bursts. But, I became suspicious because these bursts 
were about a second or so in duration consistently. During this time, I was 
testing my setup for meteor scatter using the MSK 144 software found in the 
current WSJT-X suite. These loud bursts created huge red images on the monitor 
watching in 144.150 MHz, the MSK144 calling frequency.

I got suspicious that these signals were not simple electrical pole shorting 
noise. So, I connected a whip to my old TS-790S rig and tuned it to 144.390 
MHz, the North American APRS frequency.  WALA, the signals on my monitor 
connected to a K-3 tuned to 144.150 MHz corresponded perfectly to the WPRS 
signals on 144.390 MHz, some 240 kHz away! The preamp on the K-3 was off. There 
were no other receiving preamps in line at the time. Later, I turned on an 
external 2 Meter preamp and all that happened was that the APRS signals were 
larger at 144.150 MHz. 

It appears that the front end of my K-3 simply folds up in the presence of 
strong signals that are WAY off the receiving frequency. I can tell you that 
connecting the same antenna/transverter to a Kenwood TS 590SG, there were no 
traces of the APRS signals. And connecting the TS-790S to the K1FO likewise 
produced no APRS QRM at 144.150. To me, with the presence of a number of strong 
APRS signals on 144.390 makes this K-3 extremely unusable on 2 Meters. I was 
running the K-3 noise blanker to handle the rest of the noise here but 
likewise, I also had noise blankers running on the two Kenwood radios as well. 

Any suggestions are welcome.  Dick  W5AK

[Elecraft] K2 Alignment and Test, Part II 4 MHz Oscillator Calibration

[AE0MM via Elecraft]

Making my way through the Rev I K2 manual, I've reached page 63, Alignment and 
Test, Part II. The fourth step, connect the frequency prob to TP3 and select 
CAL FCTR, my display reads 439 +/- 2; when selecting BAND- the display reads 
12086.32 steady. BAND+ and the display is back at 439 +/- 2. Digging through 
Appendix E, Troubleshooting, I can't find any steps related to this issue.

Any suggestions for troubleshooting?

Re: [Elecraft] Survey and summary: Elecraft K3/K3S panadapter solutions

[Don Wilhelm]

Dave and all,

The answer to your assumptions depends on *your* definition of I and Q 
signals, and also your ability to separate analog I/Q concepts and 
digital I/Q concepts.


I believe the K3/K3S, KX3 and KX2 already qualify as SDR transceivers - 
but they do the DSP signal processing inside the box without any 
dependency on an external computer.  Some seem to think that to be an 
SDR, you must connect with a computer - I do not share those thoughts, 
an SDR is all about mathematical processing - study a bit on DSP, that 
is "what it is all about".


I and Q signals can be defined as 2 identical signals but 90 degrees out 
of phase - period (full stop there, anything more is what adds 
confusion).  One can do "magic" with those two signals, and create 
filters, demodulate, modulate - all by manipulating the signals in the 
digital world.  It can also be done in the analog world (examples, Rick 
Campbell's phasing receivers, and the old phasing SSB exciters)


The K3/K3S does have I/Q signals, but they are digital and are at 15kHz, 
not audio, so one cannot feed them to a computer soundcard.
The KX3 has I/Q signals (and I/Q outputs) because the I/Q signals are at 
baseband (audio frequency spectrum).  The onboard computer (MCU) inside 
the radios do the processing rather than depending on a computer 
soundcard and the computer MCU for the processing.  The KX2 is similar, 
but has no I/Q outputs.


While some want to add their favorite computer software application to 
do I/Q processing separate from that done by the K3/K3S or KX3 or KX2.


The current fact is that the K3 I/Q signals exist, but they are only in 
the digital world.  The P3 does extract them, but for purposes of the 
P3, they remain in the digital world.
Getting those signals into the analog world will take some work and 
design effort.  It is more complex than a digital to analog converter.

That is not the case for the receiver in the K3 or K3S, so adding it there

Re: [Elecraft] [K3] SWR - Numerical Indication

[Mel Farrer via Elecraft]

Dick, 
While Bob is correct, the bottom line is not SWR but the R and j numbers.  
There are numerous values that will give you a 1.1:1, but only 50+j0 will be 
the true match of 1.0:1.  So,unless you do not have the equipment to measure 
the polar values, be thankful you have 1.1:1.

Yes, the K3S SWR display can show a 1.0:1 value.  But in my case,  it 
does not exactly agree with another instrument in the feed line system. 
     As to why you are showing two different values, as minute as they 
are I might add, you are measuring 2 different places in the feed line. 
   In my thinking, it is physically impossible to put two  SWR bridges 
in the same place electrically.

In theory the SWR on a given line should be the same at all places, but 
maybe not since there is loss of some minute value in the line.      
Since you are measuring on antennas, common mode current, may be the 
contributing cause.  Difference in measurement calibration, may be a 
factor as well.

VSWR bridges are calibrated with some specific value of load. Ideally, 
it is 50 ohm non-reactive, but it could be 49 ohms or 51 ohms or some 
other value.   Just because a load says "50 ohms" on the label is no 
real indication that is actually fact.    To that end, I have 3 dummy 
loads which are "50 ohm" loads according to the label but none are not 
true 50 ohm loads.    I do have a Celwave load that says 50.5 ohms on 
the label and measures 50.5 ohms per my General Radio bridge.    The 
others are +/- something, but good enough to evaluate a ham transmitter 
or amplifier.

Frankly, a difference between 1.1:1 and 1.0:1 won't make any realistic 
difference in any form or fashion other than to appease the operator.

Re: [Elecraft] Survey and summary: Elecraft K3/K3S panadapter solutions

[Dave Fugleberg]

 As I understand it, the KX3, and the P3, both contain a software defined
receiver, so the I/Q signals are already present.

That is not the case for the receiver in the K3 or K3S, so adding it there
would involve adding a SDR.

Re: [Elecraft] [K3] SWR - Numerical Indication

[Bob McGraw K4TAX]

Yes, the K3S SWR display can show a 1.0:1 value.  But in my case,  it 
does not exactly agree with another instrument in the feed line system. 
    As to why you are showing two different values, as minute as they 
are I might add, you are measuring 2 different places in the feed line. 
  In my thinking, it is physically impossible to put two  SWR bridges 
in the same place electrically.


In theory the SWR on a given line should be the same at all places, but 
maybe not since there is loss of some minute value in the line.      
Since you are measuring on antennas, common mode current, may be the 
contributing cause.  Difference in measurement calibration, may be a 
factor as well.


VSWR bridges are calibrated with some specific value of load. Ideally, 
it is 50 ohm non-reactive, but it could be 49 ohms or 51 ohms or some 
other value.   Just because a load says "50 ohms" on the label is no 
real indication that is actually fact.    To that end, I have 3 dummy 
loads which are "50 ohm" loads according to the label but none are not 
true 50 ohm loads.    I do have a Celwave load that says 50.5 ohms on 
the label and measures 50.5 ohms per my General Radio bridge.    The 
others are +/- something, but good enough to evaluate a ham transmitter 
or amplifier.


Frankly, a difference between 1.1:1 and 1.0:1 won't make any realistic 
difference in any form or fashion other than to appease the operator.

Can the K3(S) Numerical Display show 1.0:1 SWR?  If so, is there a likely
reason why K3EZ will show 1.0:1 while my K3 will only go as far down as
1.1:1?

I am not saying that at all.  The BNC connector shell connects to the

I am only saying that it may not have an RF low impedance path to the

Re: [Elecraft] Connecting a long wire antenna to the K2 with the KAT2 tuner

[Don Wilhelm]

Mark,

Yes, that GND terminal connects to the enclosure.  It is used for an AC 
Safety ground and provides some measure of protection from lightning.
If you connect it to a shack ground rod, that rod must be connected to 
the utility entry ground rod by a heavy (#4 or #6) wire on the outside 
of the building.
If you cannot connect it to the Utility Entry Ground, it is my opinion 
that the K2 (and other shack gear) is better of left not connected to 
ground.

The principles of how antennas work. RF current flows on BOTH the center 
conductor and shell of that BNC connector. It's a simple series circuit. 
The wire you CALL the antenna provides only half of that circuit -- a 
counterpoise, the other half of the antenna, provides a return path. We 
could, of course, connect it to a ground rod, but that causes the earth, 
which is a (very) big resistor, to be the return path, so it can burn 
(much) of the TX power. Far better to use a length of copper wire (a 
quarter wave is ideal) to carry that return current.


A connection to mother earth is an important part of lightning 
protection. It does NOT improve the operation of transmitting antennas. 
It IS important for many receiving antennas.

Re: [Elecraft] Connecting a long wire antenna to the K2 with the KAT2 tuner

[Don Wilhelm]

Mark,

While that might work, remember that the counterpoise(s) are a part of 
the antenna, and not a "ground".  It is better to use a BNC to binding 
post adapter and connect the counterpoise to the black binding post - no 
dependency on conductivity through the enclosure.
The BNC jack shells do not have a dependable low resistance path to the 
GND post.

Re: [Elecraft] "The Elecraft Story" - other tech books

[wb4jfi]

A good book about early microcomputing is "Fire In The Valley" by Paul 
Freiberger and Michael Swaine, originally published by Osborne/McGraw-Hill. 
Copyright 1984, It is pretty accurate up to that point.


I think that I still have a few issues of "The People's Computer Company" 
and all of the "Mark-8 Newsletter" that I need to scan in someday.  Along 
with a working IMSAI, and other old stuff.

somewhat lightweight, all of Malcom Gladwell's books are fun reads.

Re: [Elecraft] "The Elecraft Story" - other tech books

[rich hurd WC3T]

Well, I replied to Pete in a valiant effort to keep this on topic, but for
the curiosity value:

Re "The Soul of the New Machine,"  my dad knew Tom West and many other of
the engineers in the Eagle group.  He worked at RCA in Westboro and they
often went out for drinks after work together.  Blew me away when he told
me that after I told him I got the book.  :)

Wayne. 

In what “Time Frame” might it exist??
6 months, 12 months??  Never??

And while this question has also been raised; is there a possibility of mouse

Pete,

Careful, that is darn near an antique book, but I too still reference
today, kidder did an excellent
job of capturing the ethos of that team and effort.

Hi again,

Oops I accidentally sent the message without the context quote.

Get a good dummy load and you will get the indication "1.0 - 1". I have both
the K3 (souped up to near K3S) and the K3S and they both do it. You are not
confusing this with with 1.1, are you?

[Elecraft] Connecting a long wire antenna to the K2 with the KAT2 tuner

[Mark Petrovic]

Hi.  I suspect this is obvious to most readers, but to use a long wire
antenna with the K2 with the KAT2 option, one connects the antenna to the
ANT1 center conductor, and the counterpoises to the GND terminal?

Thanks.

Thanks, Mike - I fell prey to the old fallacy - "if I haven't seen it, 
it must not exist."  That said, I'd love to see something more 
up-to-date. It has always intrigued me that the KPA-1500 took so long to 
actually enter the market, having seen a prototype at Dayton about 10 
years (or so) ago. And of course, we're all waiting for the K4.


I still view Tracy Kidder's "The Soul of a New Machine" as the best 
example ever of close-up technological narrative.

Re: [Elecraft] Elecraft SW (and wsjt-x) on Ubuntu 18.04 anyone?

[Hisashi T Fujinaka]

Ah, curl. I also found a web page that documented (mostly) what I needed
to do to get k3util working on 64-bit Ubuntu (the gtk line is a bit
off).

http://sy-edm.com/stories/elecraft-k-software-in-linux.html

Turns out most of my issues are due to the serial line and the Remoterig
RRC-1258 MKII. I'm not sure how to to get the Remoterig and the computer
to share the serial line to the K3S. Still fiddling with it.

choice, there is no "install" as such.  Well, the last time I looked!

Re WSJT-X.  Should be easy, just pull the appropriate (32/64 bit) .deb
from:-

http://physics.princeton.edu/pulsar/K1JT/wsjtx.html   (Scroll down)

And install it that way, the system will/should pull any needed
dependencies (Qt5 etc) you may not yet have.

Unless you want to build from source, then follow the usual links to
source forge, but expect to have to also install several lib
dependencies, even then you'll probably need to sign up to the
developers mail list to get it to build correctly on your system. 
(Devil in the detail etc.)


I'm running the Elecraft tools on Mint 17 and 18, and WSJT-X on Mint
18.  (All 32 bit) Ubuntu derivatives of course.

The latest WSJTX tools wont run on Mint 17, as QT5 does not support
Ubuntu 14.04, that Mint 17 is based on.

You can also find the official 32 bit Windows version there too, if
anyone needs.

Anyone have any luck?

So far KPA1500Util works great. I think I may have figured out how to
get k3util working. Now I'm trying to get wsjt-x working.

The other option is to install Windows but Linux is my day job and most
of my computers run Linux/NetBSD/MacOS.

So I guess the question really is whether anyone has wsjt-x working on
Ubuntu 18.04 with their K3(S).

Thanks.

Pete,

In 2011 Wayne wrote up a nice history.  An Elecraft wikipedia page points
to it, and I put it on a web page here:

[Elecraft] [K3] SWR - Numerical Indication

[Dick Dickinson]

I've noticed that I'm not showing a reading of less than 1.1:1 SWR on my
antennas per K3 SWR Numerical Readout.  K3EZ will record 1.0:1 SWR in band
sweeps.

Can the K3(S) Numerical Display show 1.0:1 SWR?  If so, is there a likely
reason why K3EZ will show 1.0:1 while my K3 will only go as far down as
1.1:1?

[Elecraft] KDVR3 "AF play" stucked

[C G]

After recording for in excess of 90 seconds in my KDVR3/K3s, when I held "AF 
play" I repetedly got a message "end" that I could not get rid off for a while, 
even by turning the VFO B knob. Found no clue both in the manual nor the KE7X 
handbook.

Finally after pushing a lot of DVR-related commands, it unlocked. Cannot figure 
out how this happened exactly.

Anyone an idea?

Is this a bug?

73,
Christian
