Re: [Elecraft] PX3 kit tips?

[Julia Tuttle]

Hi folks,

My PX3 is up and running! The manual was a delight to follow, and
everything went together swimmingly. Thanks for all the tips -- I had
everything small neatly laid out in an egg carton, and assembling this was
probably the most peaceful hour of my day.

Here is a lousy phone picture of the finished product:
https://photos.app.goo.gl/NsXTLNo2zZPcuM4p9

One question: I performed the sideband nulling procedure, and found that my
ideal phase values were similar to the factory ones, but that my ideal
amplitude values were consistently about 25 lower than the factory ones. Is
this indicative of an issue with my equipment, build, or calibration? Or is
it within the expected range of calibration values?

Thanks and 73,

Julie

Re: [Elecraft] PX3 kit tips?

[Jim Finan]

Do a complete inventory of all parts before you begin. It isn’t unusual for a 
small piece or two to go astray.

Simply call Elecraft and they’ll send it to you. Though it may be a little 
slower than in the past with the challenges of late.

Most important- have fun!

Re: [Elecraft] PX3 kit tips?

[Bill Frantz]

Remember to take it slow and easy. Read each instruction and 
make sure you understand it. Then do it, check it off on the 
assembly manual, and go to the next one.


It is generally a good idea to inventory the parts so you 
understand which screw goes where. The small parts can be 
organized in an egg carton or a ice cube tray.


Try to get into the zen of it.

Nothing to it, you will be done in no time.  The right size screwdriver helps.  
Also try not to get fingerprints on the screen side of the lens.  Taking the 
lens off to clean them is a bit annoying.

Re: [Elecraft] PX3 Fuse Issue

[Alan Bloom]

The PX3 should draw no more than about 200 mA from the 12V supply.

When power is first applied, there will be some inrush current due to 
the filter capacitors but I'm surprised that's enough to blow a 1A fuse.


Is it a fast-blow type fuse?  Perhaps a slow-blow type would solve the 
problem.

[Elecraft] PX3 keyboard fix

[KG7WGX]

I bought a GMYLE Mini USB keyboard a while ago and tested it with the PX3 and
it worked.Then I put it aside and concentrated on my Morse speed and
learning to use a bug.Today it didn't show the "K" when I connected it. 
However, it did connect if the USB plug was pulled out around 1/16".I
applied a narrow band of heat-shrink to the USB plug and now I get a firm
connection, but the plug cannot be inserted far enough to disconnect.I don't
know if this was "tolerance stacking" and a special case or if it might
apply to other USB keyboards.If you are having intermittent connection
problems with a USB keyboard, you could try this before buying a different
keyboard.

Re: [Elecraft] PX3 signal artifact - still seeking a solution

[Philip Alley via Elecraft]

Jim,

This sounds a lot like a problem I was experiencing with my KX3 while operating 
FT8.  I was getting pulsating noise on the signal sent to the KX3 from my 
MacBook Pro laptop.  I tried all the suggestions including bonding the computer 
and putting ferrites on all signal and power leads with no improvement.  I 
finally noticed that Elecraft KXUSB cable connected from PX3 to the laptop for 
rig control has an LED which blinks at a rate (almost exactly once per second) 
with corresponds to the noise heard.  

On the MacBook Pro I was using a port adapter which allows connecting a HDMI 
cable, a USB cable and an apple Lightning power cable to one of the 4 USB-C 
(Lightning) ports on the laptop.  By simply moving the power cable from the 
adapter to a separate port the noise completely disappeared.  Since you mention 
that your foul signal disappears when you disconnect the USB cable from your 
laptop I suspect you may be suffering the same problem.  In my case, apparently 
when the LED pulses some of the power supply noise is coupled into the USB port 
and contaminates the signals.  I was worried about transmit signals and did not 
see if any artifacts were showing on the PX during receive.

Re: [Elecraft] PX3 signal artifact - still seeking a solution

[Howard Hoyt]

Hi Grant,

The shield only shields electrostatic fields and does not shield the 
magnetic field from the inner conductors.  If the garbage is on the USB 
signal lines and common mode (likely), the ferrite will still be 
effective.  If the RFI is transverse (or differential) mode, then the 
external fields from those signal conductors will largely cancel and 
ferrite will have little or no effect.


BTW, Pro Audio Engineering is a first-line Fair-Rite dealer and we have 
good stock on many mix 31 parts at good prices in small quantities.


Cheers & 73,
Howie / WA4PSC
www.proaudioeng.com


If the cable is shielded, and the garbage is on the PC's USB signal lines, 
an external ferrite won?t do any good.  I don?t know if the cable is 
shielded or not, but if it is, then the garbage may not be on the shield 
? and perhaps the USB isolator might be worth a try.  Maybe.  
I don?t know anything about that device ?

Hi Grant,

See my earlier post in this thread and the reference cited -- the 
problem is that the noise is NOT differential mode (inside the cable), 
it's common mode, and often on the shield, due to its improper 
termination inside the box.

Re: [Elecraft] PX3 signal artifact - still seeking a solution

[Grant Youngman]

If the cable is shielded, and the garbage is on the PC's USB signal lines, an 
external ferrite won’t do any good.  I don’t know if the cable is shielded or 
not, but if it is, then the garbage may not be on the shield … and perhaps the 
USB isolator might be worth a try.  Maybe.  I don’t know anything about that 
device …

Re: [Elecraft] PX3 signal artifact - still seeking a solution

[David Herring]

Jim,

Having percolated on this for a while longer, another thought comes to mind. 
You mentioned that you tried a ferrite snap-on on the USB cable. In order to 
really be effective, the USB cable would best be tightly wrapped around the 
sides of the snap-on in something of a serpentine or sequential fashion, not 
just randomly coiled up like a garden hose. I don’t know the specifics of how 
you did it, but I mention this in case you did the garden hose method 
originally…in that instance it would be a worthy exercise to rework your choke, 
wrapping it properly and seeing if that then makes a difference. 

Also, it’s not unheard of to need multiple snap-ons with multiple turns each to 
get enough impedance to choke out the unwanted signal.  Especially if you can’t 
get 6 to 8 passes through the center of a single snap-on.

Oh, and once you get the snap-on wound, it’s highly recommended to cinch down a 
zip tie around the circumference to ensure that both ends of the ferrite 
material inside are making good contact with each other. If there’s the 
slightest gap, the thing won’t work worth squat.

Hope that helps, and that at least one of these suggestions you’ve been getting 
on the reflector solves your artifact issue. ;-) 

73,
David - N5DCH

Do artifacts disappear when you have USB cable connected to the laptop but
disconnected from PX3?
Perhaps the USB cable acts like an antenna. 

For RFI transmitted via USB cable, try USB isolator. E.g.,

Re: [Elecraft] PX3 signal artifact - still seeking a solution

[David Herring]

Jim,

There is grounding, bonding and choking.  You’ve tried grounding and choking, 
it may be time to try bonding. 

Try bonding the PC to the rig with the shortest run practical of either large 
copper wire or braid. See if that has an effect on the artifact. 

Also, did the choking reduce the strength of the artifact at all? 

I have learned a lot from and thus recommend the papers on grounding, bonding 
and choking from Jim Brown, K9YC. http://k9yc.com/publish.htm

How close is the PX3 to your PS? I know my unit has spikes from the PS 
placement. Try separating or running off of a battery, if available.

[Elecraft] PX3 displaying artifacts...

[Robin via Elecraft]

I have tried this with two KX3’s with the same result. 

 

When connecting a PX3 to a KX3 and there is no antenna, the flat signal on the 
PX3 has some artifacts. The highest being where the KX3 unit is placed and then 
2 to 3 on each side symmetrically of decreasing amplitude. This means that when 
you scroll the VFO for a signal it appears as if you are always on a signal!

Usinbg the same PX3 on another KX3 I get the same.

 

Unless KX3 rigs are sensitive to some local noise (compared with a K3 where 
there are no artifacts on a P3) then it may be the PX3 itself, but what is the 
adjustment to cancel this? Any clues or suggestions would be appreciated.

Re: [Elecraft] PX3 Display During Transmit

[Grant Youngman]

Sorry.  Was in the middle of something, and had a brain f*rt.  

Anyway, no, works the same — the spectrum continues to be displayed (frozen) in 
the bandwidth window with the cursor.  It does not disappear.

I’m on the latest firmware.   If there’s a menu function that would affect that 
(can’t imagine why), I’m unaware of it.

Re: [Elecraft] PX3 Display During Transmit

[AL7CR]

On the PX3 a solid green band displays the current bandwidth of the RX filter.  
While receiving the spectrum is displayed over this block.  When I go to TX the 
spectrum on top of the green filter display disappears and only the green 
filter block is displayed.  The spectrum outside of the filter block is frozen 
and displays as normal.  When I return to RX the spectrum displays over the 
green filter block again.

I can not imagine how the KX3 / PX3 connections could have anything to do with 
this behavior.  Could it possibly be a bug introduced with the latest firmware 
or perhaps due to some combination of menu settings?

Re: [Elecraft] PX3 Display During Transmit

[Grant Youngman]

Not sure what you mean by “current filter display” — on the PX3 (?).  The PX3 
works exactly like the P3 — during transmit, the PX3 display freezes in place.  
Nothing is covered by a solid color. I’ve never seen it do what I think you are 
describing.

Have no idea why that might be happening.  Have you checked the connections 
between the KX3/PX3?

[Elecraft] PX3 Display During Transmit

[AL7CR]

On my P3 connected to my K3S when I transmit the display is frozen and shows 
the last spectrum.

I just noticed that on my PX3 connected to my KX3 that during transmit the 
current filter display covers the spectrum with a solid color.  

This does not matter much but I prefer how the P3 operates.  I did not see 
anything about this in the manual.  Is there a way to get it to operate like

[Elecraft] PX3-KX3 display question

[Daniel M. Kruss]

My KX3-PX3_KXPA100 system works perfectly, however I cannot understand the PX3 
display.  On either USB or LSB there is a significant, narrow signal spike 
which tracks the KX3 frequency.  On either USB or LSB it is at the edge of the 
cursor where the carrier (suppressed) would be.  There is no tone as I tune 
across it and it does not interfere with operation.  The waterfall does show a 
narrow trail.  If I change the XFIL from FL1 to FL2 then the spike moves to the 
center of the new, narrower passband. On CW it is in the middle of the passband.

Is this spike normal or am I setting something incorrectly?  I can send photos, 
if needed.

Thanks,

Dan  K9GDQ

To all interested:
Plain old white tooth-polishing paste, mixed with a small amount of
dihydrous monoxide, and patiently rubbed into scratches with a decent
moistened chamois, has worked for me on bezels of many kinds, even some auto
windows and paint*. Auto polish and clear auto windshield scratch-filler may
work with, eg, irreplaceable antique bezels.
Hth, and ymmv, naturally. Practice on similar scrap materials first.

candy-apple red lacquer on a '32 Ford roadster or 3-window coupe show car

I'll second Grant on Novus. I bought their 7100 kit from Amazon, and a set
of graduated polishing papers for really fine polishing.

The Novus 7100 kit is about $22 at Amazon:
https://www.amazon.com/gp/product/B002UCYRZU/
The Zona 37-948 3M Wet/Dry Polishing Paper is about $14 at Amazon:

Re: [Elecraft] PX3 acrylic scratch removal

[Grant Youngman]

The “standard” that many other radio restorers use, and I use,  is Novus 
Plastic Polish.  It comes as a set of two abrasive level liquids and a fine 
polish.  On some tough problems I've successfully used a product called 
Micro-mesh … which is a set of cloth/paper abrasives in increasingly fine 
grits.  Usually use Novus, though, unless it's a really deep scratch.

Novus is sold on-line by Walmart, tubesandmore.com, and other places.  The 
other obvious option is just to purchase a new acrylic face from Elecraft if 
it’s a major deep scratch.

[Elecraft] PX3 acrylic scratch removal

[Andy Durbin]

"Can anyone recommend a safe polish or other to aid in buffing out a minor 
surface scratch on the plastic (Perspex/acrylic?) screen cover"

Meguiar's Mirror Glaze MGH-17.

I have used it on aircraft and other transparencies.  Deep scratches may 
require work with increasingly fine abrasives.  MGH-17 will remove the marks 
left by 1200 grit.

I've used Polywatch for similar things in the past, but not on a PX3. 
So check product details first, and maybe others here know of better.

Are you sure this might not be an issue with electrical noise sourced from your

[Elecraft] PX3 display artifact caused by Elecraft USB cable

[James Smallwood via Elecraft]

Hello - I recently purchased a PX3 to support my QRP contesting efforts and am 
really glad I did. It really helps streamline S during contests.


However, when I plug a brand new Elecraft-provided USB cable for connecting the 
PX3/KX3 into my two-year old HP Pavilion PC, a 3-4db artifact appears on the 
PX3 display. No audio is associated with this artifact but it's distracting 
when viewing the PX3 display.


I'm certain the cable is the source of the issue because once the USB cable is 
unplugged the artifact disappears.



Can anyone suggest a resolution, or is this a known issue?



Thanks for taking time to consider this.

[Elecraft] PX3 for locating ft8 interference?

[Tox]

I've been using a kx3 to play with ft8. Finding intermittent severe
QRM is rendering it deaf to due desense. (Signals that are coming in
at -5 disappear from the waterfall when the source fires.)

The waterfall in WSJT-X is only really useful for a few kHz of view,
and I suspect that if the interference is notchable, it is outside
that passband.

Would the PX3 still give a full 200kHz of view to help with (maybe)
adding a notch useful for being able to then hear ft8?

I do have RTL-SDR, and Kerberos SDR, but haven't set them up for fear
of blowing out the front end when transmitting, haven't found an
equivalent to the MFJ autosensing TR switch that is solid state and
can withstand 100w of transmit.

Thanks in advance,
Scott

Re: [Elecraft] [PX3] Waterfall

[Ingo Meyer, DK3RED]

Hello Grant,



The waterfall height range adjustment is from 20-139, with 100 as the default.  
With height set to 139, slightly more than 1/2 the display is waterfall — maybe 
60%

At that height it takes about 10-11 seconds for a signal to move to the bottom 
of the display


Thank you for the detailed information.

There was only one answer direct and no one via the mailing list.

> There is a menu selection for it called Waterfall Height.

This statement surprises me, because the manual says for the menue "Waterfall" the default 
is "100" to change the height of the waterfall window when the display is in waterfall mode.


Does that mean 100% of the half display height?

And there was no answer to my second question:

[Elecraft] [PX3] Waterfall

[Ingo Meyer, DK3RED]

Dear Elecrafters,


I intend to buy a PX3. But I still have a few technical questions.

The manual says  "[DISP] toggles between the spectrum, and combination spectrum/waterfall 
display modes." Is it possible to increase the height of the waterfall to 100%, so the 
spectrum height is zero?


If the waterfall is increased to 100% height (if possible), how long does it take for a 
signal on the waterfall to reach the bottom from the top?

Re: [Elecraft] PX3 Keyboards

[Gwen Patton]

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

This is the one I got:  https://www.amazon.com/gp/product/B0787G1YFG

Re: [Elecraft] PX3 Keyboards

Don’t know what happened to the list.  Keyboard models change so frequently it 
probably got to be a mess to keep up with it.

This Logitech is a Bluetooth keyboard.  Last I saw something about it, 
bluetooth wouldn’t work because it needed a PC BIOS to make the connection.

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

[Elecraft] PX3 Cursor with KXPA100

[Grant Youngman]

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

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

To ameliorate the issue, I’ve added PA Mode ON/OFF functions as macros in the 
PX3 (since it isn’t an issue when the PX3 doesn’t come along on an outing).  
Saves digging into KX3 menus to change the PA status and is certainly quicker.

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

(I change power settings as well, YMMV).

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

Push on each one of the plugs in both the PX3 and the radio.  This can be
caused by a poor connection.

What is your CW offset set to? Perhaps that is a cursor showing the CW 
offset?

Re: [Elecraft] PX3 problems

[Bill Frantz]

An update:

I got the PX3 utility communicating with the PX3 after rebooting 
my Mac (which didn't help), and swapping the USB<--->RS232 cable 
between the two USB ports on the Mac, which fixed the problem.


I have put screen shots from the PX3 on my DropBox 
 
showing normal operation and both the vertical and horizontal smearing.


It seems I can fix the vertical smearing by holding the AVERAGE 
button and then exiting.


If no one has any ideas, I'll bug support.

Vertical smearing. It acts as if once a signal is displayed on

if I change bands on the KX3.


Horizontal smearing. It acts as if the signals on the

wider. This widening makes a CW signal about 3 times wider. 
This issue comes and goes with no obvious cause/relation to 
other things.

Remove the screws and clean the plexi. Nothing untoward will happen.

Subject: [Elecraft] PX3 LCD cover cleaning

I've got dust under the plexiglass LCD cover on my PX3. Since the 4 screws
hold the circuit board to the front of the PX3, I'm wondering if taking
those off to remove the PX3 plexiglass will cause the board to fall off the
back of the front into the box? I can't remember if the side jacks will hold
the board in place or not. I know it's a trivial process to open it up, but
I'd prefer not to just to wipe some dust off the back of the plexiglass.

I've built a KX3, a KPA500 and most of a K3 and am worried about the PX3
main board falling off the front of the enclosure...

[Elecraft] PX3 - USB thumb drive issues

[Mike Parkes]

I am having problems getting the PX3 to work with a thumb drive for
screenshot captures. I had one smaller thumb drive (32MB?) that the PX3
would mount but wouldn't save screenshots too. So I figured maybe the thumb
drive was bad and bought another one. This one locks up the PX3 or causes
the px3 to run extremely slow. This is a brand new thumb drive 128 GB size.
Is it the size that is choking the px3? Should I buy a smaller one, is
there a recommended size? The PX3 manual states nothing about what the
thumb drive requirements are to get it to work.
Thanks, 73's Mike AB7RU

Ok, try holding the menu/labels button at the lower right of the px3 to
change the bottom labels selection. It cycles through options, too. You
should get an option with no bottom labels and no text box.

Tried gain several times without success…I can’t seem to replicate the full

[Elecraft] PX3 display

Howdy Gang.

Recently picked up a nice PX3 to use with my KX3 and have been playing with the 
menu options but can’t seem to find the one I want.

I’d like to make the upper frequency portion of the display full screen….I 
don’t need the bottom waterfall.

Is this possible?

Seems like largest screen I can get is about 1/2 size.

Am I missing a menu option?

Appreciate any info/assistance.

I use my PX3 on a sailboat in a go-kit and frequently sit out in the
cockpit with the PX3-KX3 and a Raspberry PI 7" touch screen (and RPI of
course).  I do have to turn-up the PX3 LCD brightness pretty high though.
But the PX3 can get bright enough for me.  It does consume more power of
course.

The top right reads "3.800.000"

Re: [Elecraft] PX3 Span Function (WU6R - Mark)

[Brian Waterworth]

Page 25 of the PX3 manual says:

The frequency span shown on the display in fixedtune mode is limited to ±
50 kHz (100 kHz total). If you enter fixed-tune mode with a wider span set,
the span will be reduced automatically to ± 50 kHz.

:-)

Fixed tune mode was a welcome addition a couple of years ago to the PX3.

regards,

[Elecraft] PX3 Span Function (WU6R - Mark)

[Mark Wheeler via Elecraft]

Page 13 of the PX3 manual says the available span range is 2 kHz to 200 kHz, but I am not able to set my span beyond 100 kHz.  


As an example, the top left of the PX3 display reads "3.700.000",
The middle (VFO A) frequency reads "3.747.000", and
The top right reads "3.800.000"

Per the manual, I should be able to get a 200 kHz separation between the top 
left and right frequencies, but I am unable to do so by changing the span 
settings.

Does anyone know what I may be doing wrong?  

73,
Mark

Re: [Elecraft] PX3 Select knob not changing KX3 freq

[Grant Youngman]

It’s not quite clear what you’re trying to do.  

The SELECT knob on the PX3 is not just an auxiliary tuning control.  So if 
you’re twirling the knob and expect the frequency to change, it won’t. You can 
turn on say Marker A, and use the SELECT knob to move the marker.  That by 
itself won’t do anything but move the marker.  But then, if you PRESS the knob, 
the frequency will change to match the marker.

But it is not just a tuning control …

[Elecraft] PX3 Select knob not changing KX3 freq

[Mike Parkes]

I just finished putting together a new PX3 from kit, and have it connected
to the KX3. Everything seems to be working, signals from the KX3 are
showing up, and changing the KX3 vfo changes the displayed freq on the PX3.
However, the SELECT knob on the PX3 is *not *changing the displayed freq on
either device. Thanks for any help!

$100!  Good luck.

Hi John,

Reliability of the PX3 front panel circuit board and LCD is extremely high
(ditto with the P3). We do get an occasional request for LCD replacement,
usually after the PX3 has been operated portable and sustained damage in
transport.

The bezel (~$21 replacement cost) usually takes the brunt of the damage.
If a new LCD is required, it's ~$100. Replacement instructions can be
found in the PX3 Owners Manual.

I don’t think we’ve ever had to replace an entire PX3 front panel module.
We could repair it in virtually any scenario short of grizzly attack.

I called them and we did some troubleshooting of the issue.

I'm sending it back to them today. It's most likely a bad screen that will

[Elecraft] PX3 Opposite Sideband Nulling Why?

[Mal Speer]

What is the purpose of opposite sideband nulling with the PX3?
I was able to do every band except 50Mhz.
On 50 I was not able to get any change at all. The other bands nulled fine.
Is there a factory setting I can use on 50Mhz?
Tnx,
Mal WA2TWA

Re: [Elecraft] PX3 computer interface to KX3

But it doesn’t the P3 talks to the K3 at 38,400.  Weird things can happen when 
mixing nauseates. Why ask for trouble. 

BTW: My K3S came defaulted to 38,400. 

I think the 4800 on the K3 was a carryover from K2 days.

 the PX3 can get the frequency data when plugged into the same jack.
 
 I have the same problem with both wsjt-x and RUMlogNG, so I don't think

Bingo! It had been reset from 38400 to 9600. I have no idea how 
or when. Thanks for the clue.

(BTW, did I say that I hate RS232. With all the parameters that 
can go wrong, and many strange voltage conventions, it seems to 
be an interface designed to cause problems.)

[Elecraft] PX3 computer interface to KX3

[Bill Frantz]

I'm sitting in New Hampshire and I find I can't get my computer 
to talk to the KX3 when it goes through the PX3 using the 
ACC1-PC jack. The computer can talk to the KX3 when plugged in 
directly to ACC1 jack on the KX3, and the PX3 can get the 
frequency data when plugged into the same jack.


I have the same problem with both wsjt-x and RUMlogNG, so I 
don't think the problem is in the computer software. The USB 
<--> RS232 seems to be working, so I suspect the PX3.


Does anyone have any suggestions for something to fix to get 
both the computer and the PX3 to talk to the KX3? (I'm low on 
test equipment here, but I do have a DVM.)


Thanks - Bill AE6JV

[Elecraft] PX3 reset....

[Tom Francis, W1TEF]

Greetings,

Apparently I can't read owner manuals correctly.  I'm trying to reset my 
PX3 to

factory specs and I don't seem to be accomplishing that.

I'm probably missing something, but could somebody tell me what I need 
to do.


(I need to do this because I've hopeless messed up the display and I 
can't seem

to get it back to where I want it - resetting it is the best option).

Thanks in advance.

Tom, W1TEF
Lexington County, SC

Re: [Elecraft] PX3 Green Cursor Bar Color Inverting

[Alan]

The cursors look different depending on mode (CW, SSB, various digital, 
etc.)  And the mode setting is stored per band.  So probably it's just 
that different bands are set for different modes.
