[Elecraft] Ax1 fun

[Edouard Lafargue]

Brought my KX3 on a day hike in Donner Pass (California) today, and fired
it up on a small peak (George R. Stewart Peak) with the AX1 whip and its
counterpoise.

Within 10 minutes, got QSOs over ssb with the state of New York, Florida
and... Bonaire. Pretty cool on a short whip, 10 watts and a bit of luck!

Great job, Elecraft :-)

Re: [Elecraft] New KX3 Beta Firmware, rev. 2.70: Various improvements

  Oh yes, I had forgotten bias as well - ptt/bias/updown should definitely
be mode-dependent so that we can disable all those in DATA mode.

  Excellent news, Wayne!

  If only you could consider making the "Mic Btn" settings mode-dependent,
my life would be complete (or thereabouts). Right now this is the #1
setting I need to change all the time: when using the Mic on SSB I have to
enable "Ptt", and when switching to DATA to connect my audio card for
digital modes I need to set it to "Off" because the audio card jack I use
keys PTT... :)

Re: [Elecraft] KX3 SDR MAC

[Edouard Lafargue]

  Hi Fred,

   I realize I'm pretty late in the thread but... if you are willing to
experiment, you can check out my blog post here:
http://www.aerodynes.fr/2014/01/08/kx3-gnuradio-spectrum-visualisations/

This uses GNURadio to do really nice looking IQ spectrum visualizations
with the KX3. Runs great on the Mac but requires quite a lot of hands-on
action :)

There is also my own KX3 utility for the mac at wizkers.io/wizkersradio
which you should check out - it is open source too :)

[Elecraft] KX2 battery in PX3

[Edouard Lafargue]

  With all the discussion on KX2 IQ output going on, I don't want to muddle
things up even further, but as Mark KE6BB was reminding me earlier, there
is a nice way you can power the PX3 using a standard KX2 battery that I
demonstrated a couple of weeks back:


https://www.dropbox.com/s/39wjrgp1bad3xg5/KX2%20Battery%20in%20PX3.jpg.jpg?dl=0

   I did this some time ago and it works great - it looks like Elecraft
made provisions for such a battery in the design of the PX3 PCB. You need
to open the PX3 to recharge the battery, but it actually lasts for quite a
while, I haven't made precise measurements yet though.

my 2 cents,

Ed, W6ELA

[Elecraft] Wizkers:Radio update: KX2/KX3/K3 rig controller for Mac, Windows, Linux, Android and Chromebooks

[Edouard Lafargue]

Hi everyone,

   Just a quick note on the latest release of Wizkers:Radio which went live
earlier this week.

   For Elecraft users, this latest version introduces pixel-perfect fonts
for the LCD screen, which in my humble opinion look absolutely great. I can
say that since I am not the author, we owe those to Richar, OK3AR, many
thanks to him for this!

 This might sound like a gimmick, but when using Wizkers:Radio over a
VNC link to remotely control an Elecraft rig, it is actually quite nice to
have a realistic rendering of the rig front panel.

More details below:

Re: [Elecraft] Strong Rd feedback in mh3

[Edouard Lafargue]

  Thanks everyone! Good advice. Now that I have better Internet access
again (btw I meant "RF" not "Rd" in the subject line, of course), I
discovered this article on ... elecraft.com :
http://www.elecraft.com/Apps/eliminating_tx_rf_feedback_probl.htm   :-)

   I will experiment with less random lengths for my random wires, and
better counterpoises, and a small balun if necessary.

[Elecraft] Strong Rd feedback in mh3

[Edouard Lafargue]

I was operating portable today, with a long wire in a tree  and
counterpoise on the ground, and no matter what I did, every time I pushed
the mic button, I got super strong RF feedback in audio monitoring,
apparently picked up by the MH3 cable - things got slightly better if I
tried to bunch/coil the MH3 cable. Is this common?

I only managed to work one station in Indiana in the time I tried, most of
the time what I heard in my headphones while transmitting was
unintelligible garble, so it is no surprise others didn't hear me, I
guess...

My KX3 has got an internal ATU and it managed to match the long wire
perfectly at each frequency I tried to operate...

Any advice?

[Elecraft] Wizkers:Radio update for the XG3 and community forum

[Edouard Lafargue]

Hi everyone!

   Just a quick heads up: I have just released Wizkers:Radio 0.1.6, which
adds support for frequency sweeps on the XG3, a feature that was missing
and several of you asked me for. Now you have it :) Looking forward to
hearing feedback from testers.

Speaking of which: I don't want to hijack the Elecraft reflector with
discussions related to this rig controller, and I have just launched a
community forum for Wizkers:Radio at http://forum.wizkers.io/, so feel free
to register there and join the conversation.

[Elecraft] Updated KX3 rig controller

[Edouard Lafargue]

 Hi everyone,

Just a quick word to let you know that the update to Wizkers:Radio in the
Play store (https://goo.gl/ngcRXe) and the Chrome store (
https://goo.gl/SzpjII) just went live.

Two major new features in this version:

- Enhanced KX3 settings. Including an experimental KX3 memory viewer,
pending a complete editor in the next revision. This is, as far as I know,
the very first non-windows KX3 memory viewer. It is just a viewer at this
stage, and I am doing more tests before turning it into a full blown editor
soon.

- XML-RPC option in "Data Outputs": in plain english, this means that you
can now use Wizkers:Radio as a drop-in replacement for flrig !

As always, looking forward to your comments. I would be especially
interested to hear whether you can read your KX3 memories with the viewer.
The more people test, the more robust the editor will be once I make it
read-write.

I will release walk-through videos of the app over the next few days,
nothing like a simple video to help new users.

[Elecraft] Wizkers:Radio KX3/KXPA100/PX3 utility and rig controller

[Edouard Lafargue]

   Just a heads up, I have just released a new rig controller that
primarily works with the Elecraft KX line KX3, KXPA100 and PX3. If you were
already familiar with Wizkers, this is a Ham-focused version with and
extended KXPA100 monitor.

Wizkers:Radio is a universal Chrome packaged app which runs on pretty much
any computer as long as you can install Chrome on it. An Android version is
also coming up.

Wizkers:Radio supports a lot of unique capabilities such as a graph of most
radio and amplifier parameters, PX3 screenshots, a quick "memory card"
system for each KX3 band as well as support for the PKX3 PSK-D and FSK-D
modes.

And one last thing: Wizkers:Radio is fully open source, head over to
wizkers.io to learn more about the underlying framework!

Download/install link including screenshots:
https://chrome.google.com/webstore/detail/wizkersradio/fcgffipkclebcbafpgmaonlchdocnchb

Comments and suggestions are most welcome!

Re: [Elecraft] [PX3] Reversed IQ on 2m?

[Edouard Lafargue]

... and answering my own question: I just discovered you can invert
transverter bands in the PX3 settings... so it is merely a matter of
inverting the transverter bands that need it.

Sorry for the disruption - hope this will help others who run into the
issue!

  On the latest KX3/PX3 firmware, I just noticed that the IQ signal seems
to be reversed on the PX3 on 2m only - the symptom being that the higher
frequencies are displayed on the left of the screen, and the lower
frequencies on the right... Other bands behave correctly.

   I usually only direct tune on 2m, so I didn't notice this earlier. I did
a quick search on the mailing list archives and didn't find any reference
to this issue...

   Is this a known problem ?

   Precisely... this is exactly what I do on my system: I read the KX3
display on the serial port and use the SWR reading that it displays while
in tuning mode for tuning the loop automatically. If the K2 has got a
serial port, it will work too.

Why make things complicated !

Re: [Elecraft] [K2/KX3] Tuning a magloop

[Edouard Lafargue]

 No, it does not use a bridge at all, actually - no need on a KX3,
makes everything more complicated :-) . I usually use a 2W tuning power
only on the AlexLoop. So far no issues.

Re: [Elecraft] [K2/KX3] Tuning a magloop

[Edouard Lafargue]

Hi Gary,

   I need to set aside some time to finalize it, but I have designed a
fully automatic AlexLoop tuner that is designed to work with the KX3: you
just need to tune to the frequency you want to use, then press the "tune"
button on the KX3 (long press on XMIT), and the Alexloop will find the
correct tune in about 20 seconds worst case. It uses a tiny stepper motor
as you described.

   I have demonstrated a proof of concept for it at the Palo Alto Amateur
Radio Association, and I hope to have instructions ready by the end of the
year. The idea is to release complete instructions for whoever wants to
build one themselves, and maybe also offer it as a partly soldered kit for
people who do not want to bother with SMD soldering. Contact me direct if
you are interested!

Re: [Elecraft] KX3 programming question

[Edouard Lafargue]

   Jindra,

   Very happy to see yet another chrome packaged app coming up! You can
check how it is done on my existing KX3 rig controller (Chrome packaged app
too ) at http://wizkers.io/ or https://goo.gl/DgLqXH . No need to reinvent
the wheel, it's all already implemented, and all open source (AGPL)  ;-)

The code you probably want to see is there:
https://github.com/wizkers/wizkers/blob/release/server/www/js/app/instruments/elecraft/display_live.js
where I manage a proper transmission buffer that makes sure you will
transmit and receive everything with no loss. Be careful that since Wizkers
is open source under the AGPL, your own app will automatically become open
source if you reuse any of this code... Do you have a link for your app?

If you like this existing project, you are more than welcome to
contribute! Wizkers already supports cool features like rigctld support,
Piglet support, etc...

[Elecraft] Wizkers 0.10.0 released, with Piglet support!

[Edouard Lafargue]

Hi everyone,

   Just a quick note to let you know that Wizkers 0.10.0 is now released
and available in the Chrome app store, always free as in $0, and always
free as in open source at github.com/wizkers .

For current users, Wizkers will automatically update, no need to do
anything in particular. For new users, you can visit https://goo.gl/DgLqXH
to install it (yes, this is a normal link, nothing to worry about, this is
the Google URL shortener).

New in this version for KX3 users:

- Piglets are now supported! Just use "TCP/IP" in the serial connection
dialog, enter the IP/Port of your Piglet, and make sure the Piglet/Radio
are both setup for 38400 baud. That's it.
- You can now configure all the macros in the data terminal mode
(Settings menu).

As a reminder: Wizkers can be installed from https://goo.gl/DgLqXH and
the complete documentation is online (and up to date) at
wizkers.github.io/wizkers-doc/ins/elecraft-kx3/ .

Though you can already use Wizkers on two computers for remote rig
operations (http://wizkers.github.io/wizkers-doc/ins/elecraft-remote-kx3/)
, the next version will hopefully make it even easier.

Enjoy, and as always, your feedback and encouragement is always very
appreciated!

[Elecraft] KX3 SWR display when used with KXPA100

[Edouard Lafargue]

  A quick question:

 I use a KX3 + KXPA100 as my QTH setup.

 I recently did work on my QTH antenna, and the SWR indicator on my KX3 now
jumps around a lot when transmitting on digital modes, with peaks up to
2/3. As does the power output. Audio levels are good though, same as usual.
And when looking at the KXAP100 SWR LED indicator, it stays at "1" and does
not fluctuate at all. The antenna is well tuned for 20m and the ATU is able
to take SWR to 1.1 or 1.0 on that band.

  I am a bit confused: shouldn't the KX3 and KXPA100 SWR indicators show
the same values? Does the KX3 SWR indicator only indicate the link between
the KX3 and the amplifier? In which case it should remain at a steady "1"
all the time, nothing has changed on my KX3-KXPA100 link... Can someone
shed some light on this behaviour to understand what's going on?

Re: [Elecraft] KX3 SWR display when used with KXPA100

[Edouard Lafargue]

  And as a quick follow-up: when my KXPA100 is off - and my understanding
is that when it is off, it is bypassed with a relay - then I get a very
high SWR on my KX3, whereas if I connect my antenna to the KX3 directly,
then I have a great tuning...

Re: [Elecraft] [KX3] Miniature self-supporting HF antennas

[Edouard Lafargue]

 To add to the small self-supporting thread - loads of great
contributions there, thanks everyone - : I travel a lot for business, and
often carry my KX3 + Alexloop which is pretty much the only kind of antenna
that I know I'll be able to use in urban areas. This setup works really
well: on my last trip to France, I was able to do lots of digital QSOs all
over Europe, as well as several countries on phone on 20m. And I also had a
couple of QSOs on 40m with French hams who could hear me fairly well in a
large part of the country - not everywhere though, 5W on a 1m diameter
magloop on 7MHz only takes you so far.

I am in Dallas TX right now, and I spent time on 20m phone last night:
59 reports from Georgia and Montreal, CA, with a long QSO with two very
friendly hams from Canada. We even had two guys from Reunion Island join us
- one of them could not hear me, the other said he could, then band
conditions changed and everyone drowned into band noise before I could
complete the QSO... that's the life of a QRP operator.

When I know I can operate outside, a Sotabeams fiberglass pole with
thin wire and a 9:1 Unun (http://www.aerodynes.fr/2014/05/18/peanut-balun/)
do a nice job, but they are impractical in cities, of course.

Only circumstantial evidence, I know, and anyone can do a QRP phone QSO
around the globe if conditions are just right, but still, I have tried
quite a few 'hotel room' setups, and right now, Alexloop/KX3 is really my
favorite. Now, if only more North American hotels allowed their guests to
open their windows...

 My two last points:  1) I'm tempted to build an autotuner for the
AlexLoop, I have a couple of ideas on how to do this very simply, stay
tuned (pun intended). 2) Even on a Magloop, the PX3 is useful, and I would
like to make the PX3 battery operated as well. There is definitely room in
the box, and looking at the PCB, there is a connector inside just for that
purpose, right Wayne ?

 Hi all,

 Have you found the perfect above-the-treeline backpacking antenna for
 use with your KX3 or other small rig? I've used everything from a 10-meter
 coat hanger whip, to a yagi that breaks down into two dozen pieces, to a
 dipole held up at the center by a willing (and tall) campmate. The variety
 (and price range) of such antennas is staggering.

 I've had pretty amazing results using short, base-loaded antennas on the
 higher bands--especially when conditions were good. My personal best is JA
 from W6 on 15-meter SSB, running 3 watts to a Maldol 48 whip. These
 antennas collapse and break down into just two pieces, taking very little
 space in my lightweight go-bag. This leaves room for a couple of 25' wires,
 adapters, and weights for times when there are trees available.

 But the search for the ideal miniature HF antenna continues: something
 both very compact *and* highly efficient. Ideally it would break down to a
 length of 8 or less, do an excellent job on 20 meters and up, and earn a
 passing grade on 30 and/or 40 meters.

 One other key factor, at least with the KX3/KX1/K1 genre, is to take
 maximal advantage of the rig's internal ATU. A wide-range ATU (such as the
 KXAT3) can turn a narrow-banded antenna into one that covers a full band or
 even multiple bands, within limits. One general approach is to coarse-tune
 the antenna's own inductance, then let the ATU do cleanup.

 Is the best antenna for backpacking a very small magnetic loop? A cleverly
 designed, center-loaded telescoping whip? A length of #30 wire lofted by a
 small helium balloon? (Or, more intriguingly, some combination of these?)

 I'd be interested in hearing about your antenna theories and field
 experiences, backed up by entertaining fish stories, if they aren't
 embellished to an embarrassing degree. If your supporting documentation is
 too voluminous for the forum (attached photos, etc.), feel free to email me
 directly.

 If anything substantive or surprising emerges, I'll do a followup posting.

Joshua,

Very easy to do :-) I developed software to do just this, called Wizkers (
http://wizkers.io/) . it can be downloaded from the Chrome app store and
installs in a matter of seconds. Works on any computer ( and no, no need
for an Internetb connection once it is installed...)

Once Wizkers is running, it will give you a rig sharing interface so that
you can have multiple programs use the rig. I do this with RUMLog, fldigi
and jt65 at the same time, works great...

Contact me direct if you need help!

Ed, w6ela

PS: wizkers is open source, so it is also free, which doesn't hurt either.

Re: [Elecraft] Portable power - goal zero?

[Edouard Lafargue]

  Mark,

  I use a Sherpa100. Good pack, but the output voltage goes under 12V way
before the pack is empty, so the KX3 will not let you use full power after
a while. The KXPA100 is not as picky, so you can easily run a KXPA100 at
50W on the Sherpa100 until the end of the pack's power. It's a pretty good
solution imho!

   I have not tried to use the Laptop 19V output with a regulator, that
would be another approach. But on a portable power pack, you probably don't
want a linear convertor, and a switched buck convertor will introduce noise
unless you're not very careful when you design it...

   In my experience, the Sherpa100 is a fine solution. If you already have
one, just get a cigarette lighter to anderson adapter and try it out!

 Hello everyone,

 I have some questions related to running the KX-3 in the field on portable
 power.  I read through a number of threads on this site and if I understand
 correctly the KX-3 generally favors a high voltage feed.

 I am wondering if anyone is using Goal Zero system for their portable
 operation.  http://www.goalzero.com/

 Goal Zero makes excellent systems (use them for backpacking) and it’s
 basically plug and play.  The only done side I can see to their solution is
 the 12V regulated output.  I would appreciate any feedback from the field.

 Thanks,

Re: [Elecraft] DATA A mode and WSJT-X

[Edouard Lafargue]

  Thanks everyone for your super valuable input!  Flatten it was. Very
strange how much difference checking this box makes when just moving from
USB to DATA without touching anything else! I'll dig deeper in the
documentation to understand what's behind this setting, thanks for pointing
it out to me. And you are right, I need to set soundcard input super low
and AF fairly low to get a nice clean signal on WSJT.

   I'll be careful not to get hooked too much on J65 - I do like the
ragchew aspect of PSK31, and JT modes will definitely not let me do this,
that will help. But just monitoring is great fun.

   BTW: I am improving hamlib emulation in Wizkers so that I can have both
fldigi and WSJT (and others) share the radio, it's working pretty well now!
Stay tuned for a new release soon, which will also include super detailed
KXPA100 monitoring...

Enjoy your week-end!

 WSJT-X works very well with K3 and KX3 set for Digital A. As others have
 noted, we need to set the bandwidth per mode. I don't know how to interpret
 the image you posted -- there's too little time on the waterfall, and no
 amplitude display.

 This almost looks like the sort of problem that could be from a miswired
 cable, or from not having equipment bonded together properly. You should be
 using the Line Input of the K3. When the Line Input is selected, the Mic
 Gain knob acts as Line Input Gain.

 See http://k9yc.com/GroundingAndAudio.pdf for detailed advice on
 Grounding, Bonding and Audio Interfacing.

Re: [Elecraft] DATA A mode and WSJT-X

[Edouard Lafargue]

  Oh yes, I kind of forgot the most obvious :) It is KX3, running on a beta
firmware (2.33, not sure it is released yet).

  The only difference between the two sections of the screenshot are USB
and DATA A mode, nothing else changed. Very strange. The Flatten checkbox
is checked, I will try with the checkbox unchecked tomorrow morning and
report.

  On other programs like fldigi, the only difference between USB and DATA A
(both with widest possible filter bandwidth) is a cutoff at 500Hz on DATA A
whereas USB goes a bit lower.

  Thanks for all your feedback so far!

 I've used JT65 on my K3 many times, with DATA A as the mode.  I can

 The spectrum you posted was a surprise.  You should be seeing tones
 between 1270 and 1953 Hz, and they would show as discrete blips. The
 spectrum shown is not at all like that.

 I'd be scratching my head too, Ed.  It may be something simple, and

 consider this as well.  It's a little perplexing.

 Which Elecraft transceiver are you using?  Both the K3 and KX3 support

Re: [Elecraft] PX3 makes tuning in a PSK31 signal more accurately

[Edouard Lafargue]

  My 2 cents on CWT tuning: I find it usually takes two times to get it to
decode reliably: first time gets close, then pressing CWT a second time a
second later gets it right. Works best if no other PSK signal is around,
otherwise it gets confused...

Re: [Elecraft] KXPA100 Loosing Communications/ Turns PA Mode Off

  Are you using a rig controller? In my experience, depending on how
'chatty' your rig controller is,
it can interfere with the KX3/KXPA100 init routine. It is certainly the
case with mine (wizkers.io), since it
not only talks to the KX3 but also the KXPA100, every second.

 I am not sure where the glitch is occurring. I have the standard cable set

Re: [Elecraft] New KX3 rig controller

That's correct, Jeff, some USB devices are OK like sound cards.
Unfortunately, USB serial devices are not permitted, so rig control will be
tricky. There are workarounds like the Pignology, or more recently
Bluetooth LE with which Apple decided to be more open for some reason. On
Android, on the other hand, as long as your device supports USB in OTG
mode, all is fine.

[Elecraft] New KX3 rig controller

[Edouard Lafargue]

Hi everyone,

   Quick intro on the list, since I only very recently joined: Ed, W6ELA. I
have been a Ham for now a bit more than a year, and enjoying this hobby
tremendously. I do a lot of programming and electronics in my spare time as
well, and I am a long time Open Source guy.

   Related to the latter point, I have just launched Wizkers, a new Rig
Controller open source project that supports the KX3, KXPA100 and PX3, and
runs on any computer that supports Google Chrome. Mac, Windows, Linux, it
doesn't matter, it works on every OS :) Even works on any Chromebook if you
have one around.

   I made a short presentation about it at the Palo Alto amateur radio club
last Friday, and got very good feedback, so I thought I would share with
the Elecraft community as a whole.

   If you want to check it out, head over to http://www.wizkers.io/ for
more details. You will find the link to the Google Chrome store at the
bottom of the page. The overall scope of Wizkers goes far beyond Ham radio,
but as Hams, you can focus on the rig control capabilities...

   This rig controller offers unique features such as a advanced KXPA100
monitoring and charting, a very realistic and fully working KX3 panel,
direct VFO input, and an audio waterfall. And it is compatible with fldigi
too!

As an aside: besides working on any Chrome browser, you can also
install this on a BeagleBone and use this as a remote rig controller. I
have not implemented remote audio yet, but it is on the roadmap at some
point. If you have good programming skills in C++ and Javascript and would
like to contribute, you are most welcome! Get in touch with me :)

I am very much looking forward to hearing back from this group on what
you all think of it!

73
Ed, W6ELA

PS: Yes, it is an Open Source project, which means it is free - as in
freedom - as much as it is free - as in free beer.

Re: [Elecraft] K3/0 all in one box?

[Edouard Lafargue]

(First post on this reflector!)

   Well, an ethernet link can go up to 10Gbit on modern ethernet links, so
sending an 8MHz signal with a decent sampling rate and resolution is
definitely possible, but only on a local network... As an extreme, the
Arecibo radiotelescope uses RF over fiber all over the place, given its
dimensions, and they are more often than not in the GHz range!

On the other hand, if you look at tools like websdr (
websdr.ewi.utwente.nl:8901), or the Open Source project ShinySDR (
https://github.com/kpreid/shinysdr) they simply do the FFT in the backend,
and just stream the image of the waterfall which for all practical purposes
works quite well - at least that would address the remote P3/PX3 part to
a large extent. You would be able to visualize a very wide waterfall
remotely using a very reasonable bandwidth. So yes, a remote panadapter is
quite feasible...

My 2 cents, and hoping this brings value to the conversation :) (2 cents at
least)

Ed, W6ELA

 Jeff,

 I am not certain how you could send the 8 MHz IF signal over an Ethernet
 link.
 It may be possible to use some derivative of that signal - such as
 hardware using the output of the SVGA option to send the digitized result
 (SVGA signaling) of the IF passband to the control location, but to
 directly have the 8 MHz IF output replicated at the control site is much
 more complex and may be out of bounds for the FCC rules for amateur radio
 (8 MHz is not within the amateur radio spectrum allocation).
